Einstein's Painful RomanceWalter SullivanThe story of an anguished love affair between Albert Einstein and the woman who would later become his first wife has emerged in newly disclosed correspondence between them.新近披露的艾伯特·爱因斯坦与意中人(此人后来成为他的元配)之间的来往信件,向人们展示了这对情侣饱含辛酸的爱情经历。

Many of the letters describe the love between the young scientist and his future wife, Mileva Maric; the pain associated with his mother's vehement disapproval of the relationship; and their excitement over the impending birth of a child.有许多信件都叙述了这位年轻科学家和他未婚妻米莱娃·玛丽克之间的爱情,叙述了因为爱因斯坦的母亲拼命反对这门亲事而引起他俩的痛苦心情,还叙述了他俩为孩子的即将出世油然而生的兴奋心情。

The fate of the child, a girl, however, remains a mystery. She was born before the couple married in 1903 and there apparently is no record of what became of her.然而,这个女孩后来的命运如何依然是个谜。

她是在这对夫妇于1903年结婚前生下的,而且对她后来的情况显然没有记载。

Rats and Men"Insoluble" ProblemsProfessor N. R. F. Maier of the University of Michigan performed a series of experiments several years ago in which "neurosis" is induced in rats. The rats are first trained to jump off the edge of a platform at one of two doors.If the rat jumps to the right, the door holds fast, and it bumps its nose and falls into a net; if it jumps to the left, the door opens, and the rat finds a dish of food. When the rats are well trained to this reaction, the situation is changed. The food is put behind the other door, so that in order to get their reward they now have to jump to the right instead of to the left. (Other changes, such as marking the two doors in different ways, may also be introduced by the experimenter.)If the rat fails to figure out the new system, so that each time it jumps it never knows whether it is going to get food or bump its nose, it finally gives up and refuses to jump at all. At this stage, Dr. Maier says, "Many rats prefer to starve rather than make a choice."密执安大学的N.R.F. 麦耶教授几年前做过一系列可以诱导鼠产生“神经官能症”的实验。

Unit 2 Energy in Transition能源转型The era of cheap and convenient sources of energy is coming to an end.A transition to more expensive but less polluting sources must now be managed.能源资源价格低廉、使用便捷的时代已经过去了,目前应向尽管价格较高、但污染较小的资源转变。

John P. HoldrenUnderstanding this transition requires a look at the two-sided connection between energy and human well-being. Energy contributes positively to well-being by providing such consumer services as heating and lighting as well as serving as a necessary input to economic production. But the costs of energy -including not only the money and other resources devoted to obtaining and exploiting it but also environmental and sociopolitical impacts -detract from well-being.1.要了解这一转变,首先需要考察一下能源和人类幸福的双重关系。

能源为人类提供了诸如取暖、照明等消费服务的同时,也为经济生产活动提供必要投入,从这个意义上讲,能源为人类幸福做出了积极贡献。

然而,人类为利用能源所付出的代价却削弱了能源为其带来的利益,这种代价不仅包括为获取和利用能源所投入的资金和其他资源,而且包含了能源开发和利用所产生的环境影响和社会政治影响。

These diplomas won’t look any different from those awarded their luckier classmates.Their validity will be questioned only when their employers discover that these graduates are semiliterate.今年,将有成千上万的18岁学生毕业并被授于毫无意义的文凭。

这些文凭对每个人都是一样的,没有一点差别,而不管学生的成绩如何.但当雇主发现他们没有实际能力时,文凭的有效性就会被质疑。

Eventually a fortunate few will find their way into educational repair shops-adult-literacy programs, such as the one where I teach basic grammar and writing. There, high school graduates and high school dropouts pursuing graduate-equivalency certificates will learn the skills they should have learned in school . They will also discover they have been cheated by our educational system.即使少数幸运的人找到了成人进修的地方,像我教语法和写作的地方。

ABSTRACT
With the goal of developing microfluidic platforms for sensing applications, flash-free micropatterns were embossed in polypropylene surfaces with ultrasonic heating for a biosensing application.The embossed features were designed to act as reservoirs, valves, and reaction chambers to allow, in combination with a compact sensing platform, the monitoring of analyte levels using a standard PC-CD player. To generate the compact sensor, as an example, we chose the photoluminescence (PL)-based detection of lactate and glucose using an OLED-based sensing platform. Once embossed, the surface energy of the plastic substrate was chemically modified to make it hydrophilic. Reagents, placed in separate reservoirs, were directed through burst valves towards a reaction chamber via CD rotation. Lactate or glucose were monitored by measuring the effect of the related dissolved oxygen level on the PL decay time of an oxygen-sensitive dye, following analyte oxidation catalyzed by a suitable specific oxidase enzyme. The results demonstrate the potential of integrating OLEDs as excitation sources in PL-based sensors with microfluidic CD- based platforms, including for simultaneous multiple analyses.

结婚礼物伊莉莎白∙埃科诺莫我一直有这样的梦想:星光灿烂的晚上,在一家巴黎咖啡馆能有人向我求婚。

那个咖啡馆就像凡高所画的“夜晚的咖啡馆”,我的画室墙上就挂着一幅此画的翻印本。

然而,我男朋友却是在我用“稳得新”擦洗卫生间镜子的时候叫我嫁给他。

我已经上40岁,是该轮到我了。

我已经体面地让开,眼看着孪生妹妹还有小妹在我之前出嫁。

我做过女傧相7次,伴娘3次。

我的淡颜色塔夫绸衣服比寄物店都多。

我的未婚夫乔治和我都是希腊裔美国人,但是我们想办一个简朴、大方的婚礼。

不需要很多伴娘伴郎。

也不放映幻灯,展示求婚的细节,那太傻了。

这会是一次很温馨的聚会,请的人不多也不铺张,100个左右的宾客吧。

在我们的家族,那算是小圈子内的聚会。

我为一位偏狂的管弦乐队指挥做公关刚刚结束,因而我有很多时间投入到我这个新的项目上。

乔治是药剂师,每周工作60小时,现在又有一份工作:听我嘀咕婚礼一事。

这毕竟是我表现的时候,得由我说着算。

但是,我投入的时间和精力越多,万事就越和我过不去。

没有请到我想要的洛杉矶希腊乐队。

我到教堂时所戴面纱的针线活也很糟,不是我原来所要求的。

我订的象牙色的丝绸礼服被隔离在新加坡的某个地方。

眼看婚礼也就没有几个礼拜了,我邀请的客人大部分在最后期限之后才回信,让我很是烦恼。

之后,我收到妈妈的电话。

她个头娇小,68岁却依然精力饱满。

几天前还为我即将举行的婚礼感到兴奋不已。

她刚去医院做每年的身体检查。

虽然感觉还不错,但被诊断是胃癌。

接下来的几天,问题不再是“举行什么样的婚礼?”,而是“还办婚礼吗?”我把这看成是我的大喜日子。

我认识到没有妈妈的大喜日子根本就不是日子。

老爸已经在三年前过世,不可能牵着我的手到教堂圣坛完婚,这已经让我觉得凄苦。

但是一想到妈妈那天也不能在教堂就让我觉得无法忍受。

几天后,我从纽约市搬回西雅图,延迟了婚礼。

我从操办婚礼转向指导保健。

我已经挑选好歌曲,准备作为我们夫妻首个舞曲,但现在压力那么大,我已经记不起来是哪首了。

Discussion about the application of the anchor bar on theslope constructionFu Ming Fu , Zhang TianAbstract:There are some advantages in strengthening slope with the anchor bar, such as low project cost, convenient for construction and so on. It not only meets the requirement of the reliability of the construction, but also is economic and reasonable for the construction.Key words: anchor bar; slope; strengthening1.IntroductionAnchor technique uses strata geotechnical’s shear strength around bolt to deliver structures pulling force or keep strata of the excavation own stability. Due to the use of the anchor rod, Anchor strata produce compressive zone and have reinforcement effect to strata, can enhance the strength of strata, improve mechanical properties of strata, make structure and stratum together formed a kind of work together complex. Anchor system can effectively sustain tension and shear, improve shear strength of the potential sliding surface, so it can effectively prevent slope to produce sliding damage.Fig 1 after excavation of the slope2.Project profileThe length of a slope is about 60m, the most slope height is about 23m,the angle up to 50°~ 75°, a five-layer frame structure buildings is far from about 1.5 to 4m at its base edge, its foundation is artificial bored pile and its bearing stratum is in weathered phyllite. Due to the strong weathering of rocks, it was chunky, loosely structured, multi-muddy filling. It has residual slope deposits of silty clay overlying and local folder with a pulpy, low strength. Slope hadcollapsed at various locations, it is vary dangerous to the building, so we need to reinforce the slope, and we use stone concrete retaining wall and bolt to support it.3.Bolt retaining and protecting design3.1Bolt design(1)all formation of anchor use whole length bond-type, the binder materials are ordinary cement mortar, the mortar strength grade is M30, the anchor length L is 10 meters, the slope height h is 9 meters. Anchoring section length is 5m.(2)According to the construction condition and the needs of the process, the layout form of anchor use quincunx, and in order to make the anchoring force in the role of surface rock surface with uniform, the two adjacent line bolts should be staggered arrangement.(3)The anchor’s number according to /3.24 per meter to calculation, the anchor length is L, a tolal of 252. The diameter of drilling holes is φ90,the number of drill according to (L-0.1)m per hole to calculation, M30 grout number according to average 0.052m3per hole to calculation.(4)The two adjacent rows vertical spacing of anchor take 2.55m, horizontal spacing take 2.55m. The dip angle of anchor: with the angle of horizontal line is 20°, and drilling down with this Angle.(5)Anchor use the steel bar, which is HRB400 level, 28mm diameter.3.2Anchor calculation(1)The calculation of lateral geotechnical pressure[1][2]When the supporting structure to leave in rock and earth mass direction migration until to the limit equilibrium state, the geotechnical pressure which is role in supporting structure called active geotechnical pressure. Its calculation method is as follows:For the slope which has no flare structure surface, generally speaking, failure is controled by rock mass strength, the calculation formula is same to the active soil pressure, but cohesive force C take zero, internal friction angle ϕuse eϕ(rock mass equivalent internal friction angle) instead of, according to the standard to selection; rupture angle is 45°+ϕ/2(ϕis rock mass internal friction angle, is estimationed by haircut at the standard of rock mass internal friction angle, reduction factor according to the standard to selection).According to the engineering survey, active rock pressure can calculation as follows:(2)the calculation of anchor tension design value a Q ak N N γ= (1)(2) In the formula: a N is anchor tension design value; ak N is anchor tension standard value; Q γis partial load factor, take 1.3; tk H is the horizontal tension standard value of anchor; αis the dip angle of anchor.Through the calculation, ak N =112.3kN a N =145.99kN(3)the calculation of anchor steel section area(3) In the formula: S A is the steel section area of anchor; ογ is slope engineering importance coefficient(the slope engineering importance coefficient of this project is level 1, take 1.1); 2ξis the tensile working conditions coefficient of anchor bar ( permanent anchor take 0.69, temporary anchor take 0.92); y f is the tensile strength design value of anchor bar(standard value k y f =400a MP , design value y f =360a MP ).According to the calculation, S A ≥0.5883210m -⨯,choose level 3 steel of 1φ28mm,S A =0.6153210m -⨯.(4)The calculation of anchorage body and rock mass anchoring lengthanchoring length should not only meet the requirements which the bond force of formation on mortar and the bond stress of mortar on steel, but also meet the requirements that the Structure design codes the Minimum anchoring length.(4) In the formula: a l is the anchoring length; D is the diameter of anchorage body; rb f is the bond strength eigenvalue of layer and anchorage body, through the experiment or local experience sure, or according to the standard to selection ( this engineering ’s rock mass uniaxial compressive 2222111209tan (45)2090.217175.77/2222e a aE H K kN m ϕγ︒==⨯⨯⨯-=⨯⨯⨯=cos tkak H N α=2a S yNA f ογξ≥1ak a rbN l Df ξπ≥strength is 7.46a MP , belong to soft rock, rock mass structural plane development, rb f take 300a KP );1ξis the bond working conditions coefficient of anchorage body and layer (permanent anchor take 1.00).According to the calculation, a l ≥4.3m, take a l =5.0m.(5)The anchoring length between anchor steel and anchor mortara l ≥ (5) In the formula: a l is the anchoring length between steel and mortar; d is the diameter of anchor bar; n is the number of steel;b f is the bond strength design value between steel and anchor mortar, through the experiment sure, or according to the standard take 2.40; 3ξ is the working conditions coefficient of steel and mortar bond strength(permanent anchor take 0.60). According to the calculation, a l ≥2.1m ,take a l =5.0m.3.3 The construction technology and key points of anchorThe anchor ’s construction technology is as follows: build-up scaffold ——excavate and clear up the slope surface ——measures to fix position ——drill hole ——washing hole ——bolt put in a certain place ——grout ——colligation the end of the anchor ——flushing the slope surface ——pouring frame space ——Spray seed(1)This slope belong to rocky slope, after excavate the slope 10 cm to the underside of the frame space, set bolt and pouring frame space, then spray grass or seeds after borrowed soil 20 cm in the frame space.(2)the slope should be payed attention to clean up, when construction. The anchor should be placed after wash hole, then put pressure (0.4MPa) and grout. After the mortar fully solidification, colligation steel, cast-in-place reinforced concrete frame space, bend the end of the anchor and bind point by point with the skeleton steel.(3)Before drilling, the hole should be measured to fix position and then do mark. Pitch deviation is less than 150mm, hole depth error is less than 50mm. Try not remold the surrounding rock, when drill. Before Put the anchor, it should be attentioned that blow wash clean the water of the hole and rock powder and so on, and rust removal the body of rod. When grouting, builders 3a bN n df ογξπshould attention the grouting pressure and mortar ratio.Fig 2 anchor field construction drawing4.ConclusionIt is economical to reinforcement slope with bolt, and use the normal equipment, It is not only achieve safe and also economy and rational.(1) Today bolt technology is widely used in the project. It is an effective reinforcement measures to constraints sliding soil with the combining of bolt and concrete slope protection.(2) We must be sure to do geological exploration work of the slope to find out the nature of the rock and hydrogeological situation before reinforcing slope by grouting bolt.(3) Due to the factors of engineering geological conditions, grouting pressure and construction technology, we should be given adequate attention to the quality of construction.Reference[1]Technical code for building slope engineering (JGJ 120-99).
