The first ppt (0—0:20）Good morning everyone ! My name is Arvin. I come from the university of Science and Technology of China.Today I will discuss how to extract the hdyrogen by a new method.The second ppt （0:20—1:00）At present our environment is suffering from serious pollution, the blue sky has disappeared. We have to face the dreaded PM2.5 almost everyday. Why ? Why our environment become so bad. One of the important reasons is the overuse of fossil fuels, such as coal and oil. These fossil fuels have a great impact on our environment.The third ppt （1:00—1:45）Currently, the more serious problem is that the fossil energy is also vanishing rapidly. For the developing countries like china, the annual demand for energy is very large. However, Coal reserves can be only mined for 152 years and we can only use 40 years of oil. So it is emergency to find a apporpriate alternative.The fourth ppt （1:45—2:35）Hydrogen is a wonderful substitute,because it is a clean energy and also have high calorific value. There are a variety of ways to produce hydrogen. Such as biological、water electrolysis and Chemical methods. However, there methods are too expensive or unfriendly to the environment. So we propose a new method for producing hydrogen, weobtain hydrogen by the reaction of aluminum with water.The fifth ppt （2:35—3:20）If we want to use this way to extract hydrogen, we should solve two challenging problem, on the one hand, there is a native thin oxide layer on the aluminum surface which prevent water from reacting with aluminum. On the other hand, How to save the activated aluminum powder is also a big problem. Due to the activated aluminum powder is easy to be oxidized by air.The sixth ppt （3:20—3:58)In order to activate the aluminum, firstly, we add some additives into the aluminum to make alloys. Then alloy was milling with the salt. Salt can not only activate the aluminum but also protect it from air oxidation. With these methods, the aluminum can react with water at room temperature to release hydrogen.The seventh ppt (3:58—4:58)Next I will introduce some of the factors that affect the hydrogen evolution reaction. The first factor is temperature. From this graph, we can see that the conversion yield enhanced steadily with the increase of reaction time. And the hydrogen generation rate increases sharply when we increase the temperature of water.The Eighth ppt (4:58—5:50)The second factor is salt-to-aluminum mole ratio. This a indicatessalt-to-aluminum mole ratio. The following points can be concluded from this graph. First, the hydrogen evolution rate increases with the increase of the mole ratio, the total reaction time is shorter When the mole ratio is higher. Second, the conversion yield can reach sixty percent when the mole ratio is 1. However, if we raise the mole ratio above 1.5, the reaction efficiency can reach one hundred percent. Third, There is no significant difference betweeen the case with a=4 and a=7.The ninth ppt （5:50—6:48）The final factor is the effect of additives on hydrogen generation rate. From this picture we can see that hydrogen generation rate of alloys are greater than corresponding powders have no additives, The effect of adding Bi on the reaction rate is the most obvious, and the effect is the best. Additives also have the ability to omit delay time.The Tenth ppt （6:48—7:40）I have introduced that there is a dense oxide film on the surface of the aluminum. So we activate the aluminum by mechanical milling of aluminum and salt. Then we studied the effect of the salt-to-aluminum mole ratio on the hydrogen generation rate. And we find that the optimum salt-to-aluminum mole ratio was 4. Finally, we studied the effect of additives on hydrogen generation rate, Adding 7 wt% sillcon, graphite or bismuth additives can greatly increase the rate.The eleventh ppt （7:40—8:50）In the following research, we can use activated aluminum to react with saline Lake brine to extract the lithium. And we can study other more effective methods for activating aluminum powder, and we can use other better methods to produce hydrogen.Thank you ! Have any questions?。
学术交流发言稿英文
Good morning/afternoon/evening. It is my great honor to stand here today and share with you my thoughts and insights on the topic of academic exchange. As we all know, academic exchange plays a crucial role in promoting the development of science, technology, and culture in our world. In this speech, I would like to discuss the significance of academic exchange, the challenges it faces, and the ways to overcome them.Firstly, let's talk about the significance of academic exchange. In today's globalized world, the boundaries between countries and cultures have become increasingly blurred. Academic exchange provides a platform for scholars, researchers, and students to share their knowledge, ideas, and experiences with their counterparts from other countries. This process not only enhances the mutual understanding and friendship between nations but also accelerates the progress of science and technology.Academic exchange contributes to the following aspects:1. Promoting the development of science and technology: Through academic exchange, researchers can learn about the latest achievements and trends in their respective fields, which can inspire them to innovate and develop new theories and technologies.2. Enhancing international cooperation: Academic exchange fosters cooperation between universities and research institutions across the world, leading to joint research projects and the sharing of resources.3. Cultivating global citizens: Students who participate in academic exchange programs can broaden their horizons, learn about different cultures, and develop a global perspective, which is essential for their future careers.However, despite its numerous benefits, academic exchange also faces some challenges. The following are some of the key challenges:1. Language barriers: Language differences can hinder effective communication between participants from different countries. To overcomethis challenge, it is essential to provide language training and translation services.2. Cultural differences: Cultural differences can lead to misunderstandings and conflicts among participants. It is crucial to promote cultural awareness and respect among individuals involved in academic exchange.3. Financial constraints: Many scholars and students may find itdifficult to afford the costs associated with academic exchange programs, such as travel expenses, accommodation, and tuition fees. This barrier needs to be addressed through scholarships, grants, and other funding mechanisms.To ensure the success of academic exchange, the following strategies can be adopted:1. Strengthening language and cultural training: Providing comprehensive language and cultural training can help participants overcome communication barriers and adapt to the new environment.2. Enhancing funding opportunities: Establishing scholarships, grants, and financial aid programs can make academic exchange more accessible to a broader range of individuals.3. Promoting international partnerships: Encouraging universities and research institutions to establish partnerships can facilitate joint research projects and academic exchange programs.4. Utilizing technology: Leveraging technology, such as online collaboration tools and virtual conferences, can make academic exchange more accessible and efficient.In conclusion, academic exchange is a powerful tool for promoting the development of science, technology, and culture. By addressing the challenges and implementing effective strategies, we can create a more inclusive and collaborative global academic community. Let us all work together to harness the potential of academic exchange and contribute to the betterment of our world.Thank you for your attention.。

In LVCSR tasks, we need to process hundreds of hours of data. we explore 3 RBM training algorithms to minimize training time .
Traditional recognition method: combination of Gaussian Mixture Model and Hidden Markov Models (GMM/HMM) .
New recognition method: combination of Deep Belief Networks and Hidden Markov Models (DBN/HMM) . Experiments show that DBN/HMM has lower word error rate than GMM/HMM on various Recognition systems
