Fig 13FGTo explore the many other features of Registax and view helpful tutorials, go to the Registax homepage at: http://www.astronomie.be/registax/index.htmlhow neximage worksNexImage utilizes a light sensitive imaging sensor to capture streaming video of any solar system object. This video can easily be viewed as hundreds of individual images (frames) that can be digitally stacked to significantly reduce the electric “noise” inherent in video chips and bring out the unseen fine detail (signal) hidden within your image. The NexImage camera takes advantage of the fact that the signal to noise ratio of your stacked composite image is proportional to the square root of the number of frames combined. This means that stacking as few as 16 frames will reduce the grainy noise of the composite image by 4 times. While stacking as many 900 frames will improve the image by 30 times! However, stacking the individual frames is only half the power of the NexImage imager. With the included software package, each individual frame is analyzed for quality to filter out those frames most affected (blurred) by poor atmospheric “seeing”. This form of after-the-fact adaptive optics, leaves only the sharpest, clearest frames to be stacked and aligned into a high quality image. Finally, powerful processing features automatically break the image up into individual unsharp mask layers that can be used to bring out tremendous detail and reveal final images that will rival those taken with astronomical CCD cameras costing thousands of dollars.The BasicsFocusingAs with all astrophotography, sharp focus is essential for high quality results. Although there are many techniques and devices for focusing your telescope, the human eye still remains one of the best detectors of subtle changes in detail. One advantage that video imaging has over imaging with more sophisticated (and expensive) CCD cameras is the speed in which it can display its image. Focusing NexImage is more similar to focusing an eyepiece than a CCD camera. Unlike with long exposure cameras you don’t have to wait many seconds to see the effect of a focus change.8Focusing TipsTo achieve best focus, concentrate on a high contrast feature of the object you are imaging. Focusing on small features such as a moon’s shadow on Jupiter or Cassini’s division in the ring of Saturn will guarantee best focus across the entire image.Once the frames of your video are stacked, the overall brightness of the composite (stacked) image is usually brighter than its individual component frames. For this reason it is best to keep the brightness of the video image seen on the screen dimmer than you would normally desire. It is important thatno part of the image is over-exposed to assure the maximum amount of detail in the final composite image.CollimationNo matter what type of telescope you image with, poor collimation (alignment of the optics) willruin your chances for a good image. Before you begin imaging, always check the collimation of your instrument and make adjustments if necessary. Refer to your telescopes owner’s manual for instruction in collimating the optics.Finding ObjectsAt first it can be difficult to locate individual planets due to their relative brightness. To make it easier to initially find your object in the imaging window, increase the brightness and gain controls onthe Exposure Tool Bar. This will allow you to better see the object as it passes through the imaging window. Once the object is located and centered, you can adjust the setting until the object is at the desired brightness and contrast.how long to take streaming VideoAt first you may think that the more frames you record the better. However there are some limitation to the duration of video and the amount of frames you can acquire. Resolution and file size can both limit the length of time of your video.Since the NexImage will combine as many sharp frames as possible to achieve one high quality image, you don’t want to take so many images that you start to detect the rotation of the planet, especially on Jupiter which makes one complete rotation in under 10 hours!Also each frame of a high resolution video can equal a large file size. Hundreds of frames cantake up much of your hard drive space. Since file sizes of each video taken can be quite large, it is recommended that you save your video data onto a CD-ROM. This way you can have a library of files stored for processing without filling up your hard drive in the process.9AutoguidingYour NexImage 5 can be used as an autoguiding camera when used in junction with an off-axis guider or piggyback guidescope. NexImage is compatible with many autoguiding software such as MetaGuide (/Bliss/MetaGuide), and a guider port interface such as GPUSB from Shoestring Astronomy ().Specifications:Sensor 1 /2.5” format, color CMOS Sensor (Micron MT9P031)Camera Resolution5MP (2592 x 1944)Sensor Size 5.7mm x 4.28mm (7 mm diagonal)Pixel Size 2.2 micron squareSensitivity 1.4 V/ lux-sec (@550nm)USB Cable High-Speed USB 2.0 cable102835 Columbia Street • Torrance, CA 90503 U.S.A.Telephone: 310.328.9560 • Fax: 310.212.5835©2012 CelestronAll rights reserved. • Printed in China • 03-12FCC Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

我去参加中国文化博物馆英语作文
我去参加中国文化博物馆英语作文全文共6篇示例，供读者参考篇1My Visit to the Chinese Culture MuseumLast weekend, my mom and dad took me to the Chinese Culture Museum. I was so excited! I love learning about ancient China and all the cool stuff they had back then. The museum is really big with lots of different exhibits. We started in the lobby and got a map to plan our route.The first gallery we went to was all about ancient Chinese writing and books. There were these huge stone tablets with funny looking symbols carved into them. The docent lady told us they were oracle bone inscriptions from over 3,000 years ago! Can you believe people were writing way back then? They used tools to scratch words into bones and shells. It must have taken forever.Then we saw the world's oldest printed book called the Diamond Sutra. It was made from wooden blocks covered in ink in 868 AD. The pages were so delicate. I couldn't believe a book could be that old! I'm extra careful with my library books, but thisone was like a million times older. There were also cool movable type printing blocks from the Song Dynasty. Printing books must have been a huge invention.Next up was the painting and calligraphy section. The Chinese ink paintings were breathtaking with their misty mountains and twisting trees. I tried using the ink stone and brushes to paint some bamboo, but it was really hard to get it right. The calligraphy was like artwork too with all the flowing lines and shapes. Some pieces were gigantic hanging scrolls taller than my dad! I want to learn calligraphy but it looks super difficult.After that was the area on ancient Chinese technology and science. There were replicas of crazy inventions like the seismometer for detecting earthquakes and the first wood and lacquer movable type printing system. The coolest thing was this huge working model of an astronomical clock tower from the 1100s! It had all these little figurines that moved around to show the time, date, and celestial movements. I got to set it in motion and the mechanical dolls spun around. Mind-blowing that they had such advanced tech way back then!The next section covered ancient Chinese culture and beliefs. There were displays on things like Confucianism, Taoism,Buddhism, and folk religions. I thought the Buddha statues looked so calm and peaceful. My favorite was probably the Jade Burial Suit made of thousands of jade pieces sewn together with threads of gold, silver, and silk. It was over 2,000 years old! The docent said it was meant to preserve the body in the afterlife. The craftsmanship was insane. I've never seen so much jade in one place.Then we went upstairs to check out the Chinese arts and crafts. They had glass cases filled with the most ornate pottery, bronze vessels, lacquerware, and porcelain. The ceramics had the most vibrant blues and yellows. Many were shaped like animals like dragons or phoenixes. There were also musical instruments like giant bronze bells and ceramic ocarinas. I got to try playing a sheng mouth organ and made some pretty funky sounds!Towards the end was the exhibit on Chinese clothing and textiles through the ages. There were recreations of lavish dragon robes worn by emperors with intense embroidery. One had over 26,000 seedsparingly sewn into it! I can't imagine how long that took. There was also this huge heavy bride's dress made of colorful rolled satin that must have weighed a ton. I'm glad I just wear a regular dress to weddings.The last stop was the Chinese garden area outside with ancient architecture and landscaping on display. We wandered through the corridors and pavilions surrounded by bamboo forests, rock gardens, and ponds with limestone bridges. There was even a mini version of the Forbidden City! I loved the vibrant painted beams and tiled roofs with figures of creatures. We sat down near a zigzag bridge over a koi pond filled with water lilies and I snapped some pictures. Such a serene atmosphere.By the end of the day, my brain was exploding with new information! I had no clue how advanced and amazing ancient Chinese culture and achievements were. The museum made me appreciate my heritage so much more. All the artifacts and exhibits were meticulously preserved. I felt like I traveled back thousands of years and got to experience it firsthand. I can't wait to go back and explore the other galleries I missed. Maybe next time I'll attend one of the museum's calligraphy or pottery classes!篇2My Visit to the China Cultural MuseumHi everyone! I'm so excited to tell you all about my trip to the China Cultural Museum last weekend. My mom and dad took methere for a fun family outing, and I had the best time learning about our amazing culture. Get ready for an awesome adventure!When we first arrived, I was in awe at how huge the museum was. It's this gigantic red and gold building that looks like a palace from ancient times. My dad said it was designed to look like the Forbidden City in Beijing. As we walked through the entrance, I felt like a little emperor going into my royal home!The first exhibit we saw was all about Chinese festivals and holidays. There were these life-sized displays showing people in bright, colorful costumes celebrating things like Chinese New Year, the Mid-Autumn Festival, and the Dragon Boat Festival. I loved seeing the dragon and lion dances! My favorite was the New Year display with the yummy-looking candies and the red decorations everywhere for good luck.Next up was the art gallery, and let me tell you, it was breathtaking. They had hundreds of ancient paintings, ceramics, calligraphy scrolls, and jade carvings. Some of the porcelain vases were so beautiful and delicate. My mom tried to teach me about the different Chinese dynasties that created each style of art, but there was so much to take in! I just remember the blues and whites were from the Ming period, and the bright greensand yellows were Song dynasty. Maybe I'll be an art expert when I'm older!After the art, we went into the section on philosophy, literature, and inventions. This part had really old books and scrolls under glass cases. My dad said the works dated all the way back to Confucius and the very first Chinese writings! They also showcased the "Four Great Inventions" that came from ancient China - the compass, gunpowder, paper, and printing press. Can you believe people started using paper and compasses thousands of years ago? Mind-blowing!My favorite area was definitely the Chinese mythology room. It was decorated to look like this mystical, foggy mountain scene with stone pathways winding through the middle. Statues of dragons, phoenixes, Buddhas, and immortals lined the trails. I loved reading about the crazy stories of monkey kings,eight-immortal warriors, and the journey to the west. The myths were so imaginative and action-packed! After that room, I really want to be a kung-fu master who can fight demons and monsters.The last section we visited focused on traditional Chinese architecture, furniture, and clothing styles throughout history. They had this gigantic multi-level model of a Forbidden Citypalace that looked like a mini city within itself. My dad pointed out all the symbolic lions, dragons, and phoenix carvings decorating the rooftops and pillars. In another room, they had replicas of thrones, beds, cabinets and pottery from imperial living quarters. We also saw mannequins wearing different types of robes, gowns, and armors from dynasties like the Han, Tang, and Qing. The silk dresses were so fancy and flowy!After hours of exploring, we finally made it to the museum gift shop. I was so tempted by the cool souvenirs like mini terracotta warrior statues, traditional Chinese fans, and candy boxes painted like ancient vases. In the end, I convinced my parents to buy me a traditional Chinese jacket covered in an awesome dragon pattern. I've been wearing it nonstop since our trip! I may have also smuggled out a couple little warrior figurines in my pocket...don't tell mom and dad!That's the full scoop on my amazing China Cultural Museum adventure. I can't wait to go back and see the other exhibits on Chinese opera, cuisine, and ethnic minorities. Learning about my heritage was the best day ever! I'm so proud to be Chinese after experiencing the incredible history, arts, and traditions. I hope you enjoyed hearing about my exciting cultural journey. Thanks for reading!篇3My Trip to the Chinese Culture MuseumWow, I'm so excited to tell you about my amazing field trip to the Chinese Culture Museum! It was the coolest and most fun museum I've ever been to. I learned so many awesome things about the incredible history and traditions of China.We went on a big yellow school bus that took forever to get there. I kept asking "Are we there yet?" but it still took a really long time. When we finally arrived, the museum was this huge building that looked like an ancient Chinese temple with beautiful red pillars and dragon sculptures. I could already tell this place was going to be epic!The first exhibit we saw was all about Chinese jade carvings and art. There were these tiny jade statues that were carved with incredible detail - they had little people, animals, and scenes from stories all carved into the jade stone. Our tour guide said some jade carvings are so tiny they can fit in the eye of a needle! He let us try carving jade with special tools and it was super hard.I have a new respect for jade carvers after that.Next up was the calligraphy room where we learned about the traditional Chinese art of beautiful handwriting. We all got totry using bamboo brushes and ink to write Chinese characters. It took a lot of practice and my handwriting looked like chicken scratches compared to the amazing calligraphers' work that was on display. But it was still really cool to learn this ancient art form.My favorite part was definitely the exhibits on ancient Chinese inventions and technology. Did you know that the Chinese invented the compass, paper making, printing, and even gunpowder?? They had all these old compasses and formulas for making gunpowder on display. I got to try using an abacus, which is an ancient Chinese calculator tool made of beads on rods. It was really hard at first but then I started getting the hang of doing math with it.We also saw awesome exhibits on Chinese clothing, festivals, pottery, and more. They had these giant vases and bowls from thousands of years ago that were so ornate and colorful. I liked the exhibits showing traditional Chinese clothing like the dragon robes that emperors wore. They were made of bright silks with patterns of dragons embroidered on them and looked so royal and fancy.I think my favorite thing of all was the Chinese shadow puppetry display. They had this little stage set up with puppets made of leather that cast shadows on the screen. We all got totake turns putting on a shadow puppet show and making the pupp篇4My Visit to the Chinese Culture MuseumWow, I had the coolest experience last weekend! My mom and dad took me to this huge museum all about Chinese culture. At first, I wasn't super excited because I thought it might be kind of boring. But boy was I wrong! The museum was awesome.We started off by watching a movie about the history of China. It went all the way back to ancient times, thousands of years ago. The movie had cool animated parts and everything. I learned that China is one of the oldest civilizations in the world! The people back then were really smart and invented a ton of important things like paper, printing, the compass, and gunpowder. Wild, right?After the movie, we went into the first exhibit hall. It was all about Chinese writing and calligraphy. There were these massive scrolls on the walls with beautiful inky characters. The writing looked like art! I got to try using a calligraphy brush to copy some characters. It was really hard to get them looking nice. I have a new respect for calligraphers!Next up was the exhibit on ancient Chinese inventions and technology. You wouldn't believe all the genius ideas they had way back when. The museum had models of crazy contraptions like wooden rabbits that could spin around and these cool hand warmers that you could carry with you. My favorite was this primitive robot toy from the 3rd century! They even invented things like matches and the fishing reel way before the West did. Mind-blowing.The part I loved most was the Chinese clothing exhibit. They had all these colorful traditional outfits from different regions and time periods behind glass. I loved the dragon robes worn by emperors. They were so ornate and decorated with embroidered designs. The museum let me try on a replica kid-sized outfit. I felt like royalty! The ladies' dresses were gorgeous too, especially the bright red wedding gowns.We spent a long time exploring the Buddhism and Taoism area too. I saw these huge, peaceful-looking Buddha statues and amazing artworks showing deities and mythological creatures. That part was a bit over my head, but visually it was breathtaking. All the murals and paintings were so vibrant and detailed.By the time we got to the sections on literature, music, and Chinese opera, I was getting a little tired. But that stuff was stillreally interesting to learn about. There were displays on classic books and scrolls with some of the most famous poems and stories. We watched a cool performance of traditional Chinese opera singing and music. The costumes and makeup were just wild篇5My Trip to the Chinese Culture MuseumWow, I'm so excited to tell you all about my amazing trip to the Chinese Culture Museum! It was the coolest field trip ever. I had been looking forward to it for weeks and weeks.On the morning of the trip, I woke up super early because I was too pumped up to sleep in. I gobbled down my breakfast rice krispies as fast as I could. Then I brushed my teeth like a million times to make sure my breath wasn't stinky. I wanted to be ready!The big yellow school bus pulled up right on time. I raced to get a window seat in the very back row. Those are the best seats on the bus for sure. My best friend Amy managed to nab the seat next to me. We were both buzzing with energy, chatting about all the awesome things we would see at the museum.After a drive that felt like FOR-EV-ER, we finally made it! The museum was this massive traditional-style building with beauuuutiful gardens all around it. Our teacher gathered our class together. "Remember to stay with your buddies and listen carefully to the museum guides," she instructed sternly. Yeah, yeah, we all nodded impatiently. We just wanted to go inside already!The second we stepped through the doors, my jaw dropped to the floor. The entrance hall was dimly lit but you could see the glow of these ginormous terracotta warrior statues lining the walls. They were so life-like and rad-looking with their fierce expressions. I was in awe!Our group followed the guide into the first main exhibit space. It was all about ancient Chinese history and archaeology. There were shards of primitive pottery, old bronze cookware, and intricate jade carvings. Amy and I had fun trying to decipher the strange symbols and patterns etched into everything.Next up was the folk art and traditions section. I loved examining all the brilliant, vibrant designs on the embroidered silks and colorful masks. The teapot collections were pretty neat too, with some pots being hundreds of years old! We eventriedwriting our names in calligraphy. That brush painting stuff is way trickier than it looks.One of the craziest exhibits showed molded figures doing all kinds of bizarre, acrobatic poses. Our guide explained they were sculptures of moves from the Chinese martial arts and circus arts. Just looking at them made my bones ache! How do people's bodies even bend that way? I tried standing like one of the sculpted acrobats and immediately fell over.We took a break to rest our feet and eat our sack lunches. I scarfed down my sandwich and Doritos in about two seconds. No time for loitering - there was so much other cool stuff left to explore!The clothing gallery was probably my favorite part of the whole museum. They had dresses, robes, and costumes from different dynasties and provinces all displayed on mannequins. The emperor's golden silk robes looked heavy enough to weigh a thousand pounds! My absolute favorite outfit was this bright pink tunic with a floral phoenix design that a young princess once wore. I can't even imagine how uncomfortable and itchy all those fancy getups must have felt.After the textiles, we wandered through rooms dedicated to traditional music, theater, and dance. We watched a short videoshowcasing spectacular acrobatic choreography from the Beijing Opera. I wish I could bend and tumble like those super-human performers! Our guide also taught us a few basic hand gestures used in the performances to symbolize different characters and events.Towards the end, we entered a huge modeled scene depicting an ancient riverside village. All the tiny figures and buildings gave you a glimpse into what daily life was like centuries ago. I spotted teensy oxen pulling carts and women washing clothes in the stream. Amy and I spent forever examining every little detail in the scene. We didn't want to miss anything!After what felt like a billion hours, it was finally time to go. My poor little feet were absolutely killing me from all the walking around. Still, I felt a little sad to leave the museum behind.On the bus ride back to school, I was utterly exhausted but totally overcome with happiness from the amazing experience. I learned so much mindblowing stuff about China's rich history and traditions. Things I never could have fully understood just reading about them in textbooks.I'll never forget the first moment I laid eyes on those terracotta warrior guardians. Their scowling faces wereintimidating yet fascinating. Or examining the ornate embroidery and realizing just how patient and skilled historic artisans had to be to produce such breathtaking needlework. From the tiniest pottery shard to the most lavish imperial robes, everything gave me a new appreciation for my ancestors' incredible talents and customs.This field trip showed me there's a whole universe of wonders waiting to be uncovered from China's past. I can't wait to go back and learn more! Maybe I'll evenbe an archaeologist or museum curator when I grow up. One thing's for sure - this was an adventure I'll always cherish. The Chinese culture is just endlessly fascinating!篇6My Visit to the China Culture MuseumWow! I went to the coolest museum ever - the China Culture Museum! It was so much fun learning about the amazing culture and history of China. I want to tell you all about my exciting adventure.First, we went into this huge room that had tons of really old pottery, jade carvings, and bronze items. My teacher said they were from ancient Chinese dynasties like the Shang, Zhou, andHan. I couldn't believe some of those fragile looking vases and cups were over 2,000 years old! They looked brand new. The jade carvings were my favorite though. There were little jade animals like dragons, horses, and rabbits that were so detailed. I don't know how the artists made such tiny, perfect cuts in the hard jade rock. It's like magic!Next, we saw a big exhibit on Chinese calligraphy. That's the fancy Chinese handwriting that uses brush pens and ink. The calligraphy was so beautiful, like little dancing people on the paper. We got to try writing with the brush pens too. It was really hard to make the strokes look good. My letters came out all blobby. The museum teacher said I need more practice. Calligraphy is tricky!After that, we went upstairs to this enormous room filled with ancient weapons and armor from Chinese warriors. There were crazy looking swords, spears, crossbows, and these armored shirts made from small wooden pieces laced together. Everything looked so heavy and dangerous! We learned that Chinese soldiers used those weapons to defend against enemy attacks. I tried lifting one of the swords and could barely move it an inch. I don't know how those warriors fought battles carrying all that heavy gear. They must have been super strong!The best part was the section on Chinese music and dance. We saw these beautiful old instruments like the guzheng, pipa, and erhus. The guzheng looked like a really long zither with lots of strings stretched across its surface. The pipa was thispear-shaped stringed instrument that was played with finger picks. And the erhus were these tiny two-string fiddles that made such a cool, haunting sound. We watched a video of performers playing those instruments and saw them do ribbon dances and martial arts moves on stage. It was mesmerizing! I want to learn to play the pipa when I'm older.We also got to dress up in Chinese opera costumes and try on these crazy opera masks. The masks had giant eyes and exaggerated expressions like sadness, anger。

日本研究：蛋白质血管内皮生长因子是脑出血诱因 ．治疗脑梗塞时，利用药物溶解血栓是首选的治疗方法，但是发病３小时以上用该疗法可能导致脑出血。日本研究人员日前发现，一 血管内皮生长因子（ＶＥＧＦ）的蛋白质是导致脑出血的诱因，并且开发出了抑制这种蛋白质功能的方法，从而使脑梗塞发病后允许 －溶解疗法的时间大幅延长。
，一成果由新渴大脑研究所教授下烟亨良率领的研究小组获得，也是世界上首次弄清血栓溶解疗法导致脑出血的机制。相关论文已经 了英国《脑血流与代谢杂志》（Ｊｏｕｒｎａｌ ｏｆＣｅｒｅｂｒａｌ Ｂｌｏｏｄ Ｆｌｏｗ．＆Ｍｅｔａｂｏｌｉｓｍ）上。
