The third point, most difficult of all to understand, is that students of history seem intentionally to refuse to see that this march cannot be ascribed to any one man, that no one foresaw it at any time, that, like the retreat to Fili, the manuvre was, in reality, never conceived of by any one in its entirety, but arose step by step, incident by incident, moment by moment from a countless multitude of the most diverse circumstances, and is only conceived of in its entirety, when it is an accomplished fact, and has become the past.

第三，令人最难以理解的是，研究历史的人故意不愿看见，这次侧翼进举不能归功于任何一个人，在任何时候都没有任何一个人对它有所预见，从菲利的撤退也和它完全一样，在任何时候都没有任何一个人看清楚它的全貌，它是由无数的各种各样的条件一步一步地、一个事件接着一个事件、随着时间的推移逐渐显露出来的，只有当它已经完成和已经成为过去的时候，它的全貌才呈现出来。

安业务定义的时间，其中一个说，观测了一些重复的一种或另一种标准的周期性活动构成一个标准的单位，如第二次，是非常有用的情况下先进的实验和日常事务的生活。

Mumps one pound, that is what I have put down, but I daresay it will be more like thirty shillings -- don't speak -- measles one five, German measles half a guinea, makes two fifteen six -- don't waggle your finger -- whooping-cough, say fifteen shillings -- and so on it went, and it added up differently each time; but at last Wendy just got through, with mumps reduced to twelve six, and the two kinds of measles treated as one.

Then, on the basis of above achieved constituent binary results, thermodynamic properties of 10 ternary liquid alioys (Cd-Bi-Pb, Cd-Pb-Sb, Cd-Pb-Sn, Mg-In-Cd, Zn-In- Cd, Cd-Bi-Sn, In-Bi-Pb, Sn-AgPb,Zn-In.Pb, Al-Cu-Zn), 3 quaternary ones (Cd-Bi-Pb-Sn, Zn-Sn-Cd-Bi, Zn-Sn-Cd-Pb) and 1 quinary. one (Zn-Sn-Pb-Cd-Bi) are predicted. For most of investigated multicomponent systems, the calculated activities are in good with the experimental ones, and in particular for multicompoment immiscible ones, the predicted results are satisfactory and exciting. At the same time, the comparison result between the three equations shows that Wilson equation and T-K-Wilson one are more stable than NRTL one, that maybe is because NRTL equation contains a third parameter, and so ,to some degree, Wilson model and T-K-Wilson model are superior to NRTL model. And also the comparison between local composition models and other models such as Pelton- Flengas?method, Krupkowski formalism, mass action concentration model and Hoch- Arpshofen model shows that local composition models are more convenient and credible.

在此基础之上应用局部组成型模型对10个三元液态合金（包括Cd-Bi-Pb、Cd-Pb-Sb、Cd-Pb-Sn、Mg-In-Cd、Zn-In-Cd、Cd-Bi-Sn、In-Bi-Pb、Sn-Ag-Pb、Zn-In-Pb、Al-Cu-Zn），3个四元液态合金（包括Cd-Bi-Pb-Sn、Zn-Sn-Cd-Bi、Zn-Sn-Cd-Pb）和1个五元液态合金（Zn-Sn-Pb-Cd-Bi）的活度进行了预测，预测效果良好，尤其对Zn-In-Pb系和Zn-Sn-Cd-Pb等多元液-液共存体系热力学性质的预测也取得了令人满意的结果；同时对三个方程的比较分析表明：Wilson方程和T-K-Wilson方程在多元系热力学性质的预测中表现稳定，而NRTL方程由于引入了物理意义不清楚的第三参数，使得其具有不确定性和不稳定性的特点，因此Wilson方程和T-K-Wilson方程较NRTL方程更为优越；此外对局部组成型模型与其它模型（如Pelton-Flengas方程、Krupkowski方程、作用浓度模型和Hoch-Arpshofen模型）的比较表明：局部组成型模型同样是优秀的，甚至在某些方面更为简便和可靠。

I was so amaz'd with the Thing it self, having never felt the like, or discours'd with any one that had, that I was like one dead or stupify'd; and the Motion of the Earth made my Stomach sick like one that was toss'd at Sea; but the Noise of the falling of the Rock awak'd me as it were, and rousing me from the stupify'd Condition I was in, fill'd me with Horror, and I thought of nothing then but the Hill falling upon my Tent and all my houshold Goods, and burying all at once; and this sunk my very Soul within me a second Time.

我以前从未碰到过地震，也没有听到经历过地震的人谈起过，所以我一时吓得目瞪口呆，魂飞魄散。当时，地动山摇，胃里直想吐，就像晕船一样；而那山石崩裂发出震耳欲聋的巨响，把我从呆若木鸡的状态中惊醒过来，我感到胆战心惊。小山若倒下来，压在帐篷上和全部家用物品上，一下子就会把一切都埋起来。一想到这里，我心里就凉了半截。

The solid immersion lens can be used into an optical storage system It provides the high NA of the system and uses the evanescent wave to produce extremely small optical spots Two proposals about a SIL are given out here The first one is that the protecting layer of the recording layer can be used as one part of the hemi spherical SIL So the recording layer is not polluted The second one is that a SIL can be used at same time in a double layers storage The first recording layer is used a...

固体浸没透镜用于光存储光学系统增大了光学头物镜的数值孔径，利用近场倏逝波读写，减小了光斑的直径，提高了存储密度。文中建议：(1)将半球SIL分割成两部分，其中一部分由存储媒质的保护层充当，避免直接污染记录层；(2 )在半球SIL单层读写的基础上，再将第一层记录媒质作为SIL的一部分形成超半球齐明SIL ，以实现双层存储。并对此时的近场进行了解析分折

Going through my past, I could see my perseverance was not inherited from my parents whom obviously different from me on this point, and I remember when I was young I never put my heart into one thing for a long time, today did this, tomorrow that, can't have got one thing satisfied, so I was the useless one in the other's eyes.

回想过去，我知道我那坚定不移的性格并不是从我父母那里继承过来的，他们在这一点上和我是那样的不同。我记得，我小时候，我从没有专心，长时间的关注过一件事，今天做这个。明天是那件。从没有做好国一件事情。因此在他们眼里，我是个没出息的人。

Afterwards, we propose a new constant coefficients measurement method in dynamic equation of robot manipulators, this measurement method includes three groups of experiments: group one, let each joint of robot manipulator keep static to measure the constant coefficients in gravity term of dynamic equation and Coulomb frictional torque, group two: let only one joint of robot manipulator move at a constant velocity to measure the viscous frictional coefficient and constant coefficients in effective inertia of dynamic equation, group three: let only one joint of robot manipulator move at constant acceleration at a time to measure constant coefficients in Coriolis and centrifugal term and coupling inertia of dynamic equation.

让操作器单个关节恒速运动，在对驱动系统中传动机构，减速装置和电感系数综合考虑的基础上，这组实验对粘滞摩擦系数及有效惯量中常数系数进行测量。这种测量方法只要求旋转关节的驱动电机施加恒定电压，回转关节驱动电机施加正弦波电压。3。让操作器单个关节恒加速运动，这组实验测量动力学方程中哥氏力、离心力项和耦合惯量项中的常数系数，这种测量方法只要求单个关节匀加速运动，而其它各关节保持静止，这种测量方法虽然要求关节匀加速运动，但不必进行关节角加速度检测，而只需进行关节角位移和角速度检测即可，输入量直接给定为输入电压。
