The first thing we need to do is determine the mean ecliptic longitude of the sun for your chosen day. Use this table to get a first approximation.

第一件事，我们需要做的是确定的意思，黄道经度的太阳为你的选择每天使用此表，以获得第一次逼近。

This work resulted, contrary to my own expectation, in the first direct experimental proof…of the Einstein equation and the first direct photo-electric determination of Planck's h.

密立根的诺贝尔获奖演说中的一些内容仍然表明他对其工作真正意义的抗拒："与我的期望截然相反，这项工作第一次直接实验验证了爱因斯坦的光电方程，并第一次直接测量得到了普朗克常数"。

With the acceleration of industrial growth came acute urban crowding and accompanying accompanying social stress -- conditions that began to approach disastrous proportions when, in 1888, the first commercially successful electric traction line was developed.

拥挤和相伴而来的社会压力。当年第一条商业上成功的电气化铁轨被制造出来时， 1888 年第一条商业上成功的电气化铁轨被制造出来时，压力开始接近危机的程度。力开始接近危机的程度。

An electrosurgical cutting blade ( 1 ) comprises a first electrode ( 2 ), a second electrode ( 3 ), and an electrical insulator ( 4 ) separating the first and second electrodes.

The first part is also chapter 1, is the introduction part, carrying on the elucidation for some basic problems.

第一部分也就是第一章，是导论部分，主要就本文的一些基本问题进行了说明。

The model in this paper takes the form as belowThe main contents and results in this paper are as follows:In section 1, we state our main analytical results on equilibria of the above system. First, several sufficient conditions for coexistence of the steady-state are given by the standard fixed-point index theory in cone. Second, the global structure of the coexistence solutions and their local stability are established by using bifurcation theory. Third, the multiplicity, uniqueness and stability of positive steady-state solutions to this system are derived by means of perturbation theory of eigenvalues, standard regularity theory, Sobolev embedding theorem and fixed-point index theory.

本文主要有两章内容：第一章研究了该模型正平衡解的性质，可分为三部分：第一部分运用极值原理、上下解方法和锥映射不动点指标理论得到正平衡解存在的充分条件；第二部分利用分歧理论给出了平衡态系统正分歧解的结构，并讨论了局部分歧解的稳定性；第三部分利用特征值扰动理论、标准椭圆正则化理论、Sobolev嵌入定理及指标理论讨论了正平衡解的多重性、唯一性及稳定性，并讨论了参数对解的影响。

Today is the first time for my son to go to kindergarten, the frist time to leave my family to go to a entirely strange place , I don't know whether he will suit soon ,whether he will loudly cry ,whether he will make the emiction in his trousers, whether he won't go in a few days…… Though he looked forward to there for a long time, he gladly told his father he will go to the kindergarten last night, but I really don't know what he is doing at the right, I'm really afraid of him, though I know this faraway worry no help for him, but he is just very small,if he is a little big ,maybe I can be better.

小楠今天第一天上幼儿园，第一次真正离开亲人，去一个陌生的环境，不知道他会不会很快适应，会不会大哭，会不会尿裤子，会不会以后不想去了。。。。。虽然那里早就是他向往的地方，昨天晚上还兴高采烈的告诉他爸爸，他要上幼儿园了，可是真不知道此时此刻他在干什么，真的很担心，尽管我知道这种遥远的担心根本无济于事，可他毕竟还小，如果再大点，我可能就会好很多。

We all have a friend who knew us when...maybe way back in Miss Meltzer's second grade, when our family lived in that tree-room flat in Brooklyn, when our dad was out of work fo seven months, when our brother Allie got in that fight where they had to call the police, when our sister married the endodontist from Yonkers, and when, the morning after we lost our virginity, she was the first, the only, friend we told.

也许可以追溯到二年级的时候，当时我们家住在纽约市布鲁克林区的一套三室公寓。我父亲失业七个月，我哥阿里参与了一起斗殴事件都惊动了警察局，我姐嫁给了一个扬右克斯市的牙根管医师，当我不再是处女的第一个早晨，她是我透漏秘密的第一个且是仅有的一个朋友。

" Bradford , William :English-born american colonial printer whose press produced the first american Book of Common Prayer (1710), New York City's first newspaper (1725), and numerous other items."

布拉德福，威廉：英裔美籍殖民印刷商，他的出版社发行了第一批美国版本的英国国教祈祷书(1710年)，纽约城的第一张报纸(1725年)及大量的其他印刷制品。

When the first Englishmen went to New England in 1620, their first year was very hard.

当第一批英国人于一六二零年来到新英格兰，他们的第一年很艰苦。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
