In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.

When we told them how we plac'd our selves, and the Horses in the Middle, they blam'd us exceedingly, and told us it was fifty to one but we had been all destroy'd; for it was the Sight of the Horses which made the Wolves so furious, Seeing their Prey; and that at other Times they are really afraid of a Gun; but the being excessive Hungry, and raging on that Account, the Eagerness to come at the Horses had made them sensless of Danger; and that if we had not by the continu'd Fire, and at last by the Stratagem of the Train of Powder, master'd them, it had been great Odds but that we had been torn to Pieces; whereas had we been content to have sat still on Horseback, and fir'd as Horsemen, they would not have taken the Horses for so much their own, when Men were on their Backs, as otherwise; and withal they told us, that at last, if we had stood altogether, and left our Horses, they would have been so eager to have devour'd them, that we might have come off safe, especially having our Fire Arms in our Hands, and being so many in Number.

狼主要是想吃马。它们之所以那样奋不顾身冲上来，是由于看到了我们身后的马。一般来说，狼是怕枪的，但当它们饿疯时，就会不顾危险，只想抢马吃了。要不是我们连续开枪，并且最后用点燃火药的办法把他们吓退，我们大概早就给那些饿狼撕成碎片吃掉了。其实，只要我们安安稳稳地坐在马上，像骑兵那样向狼群开枪，它们看到马上有人，就不会把马看作猎物了。最后，他们又说，如果我们大家紧挨在一起，丢开我们的马，狼就一心只想吃马而不会管我们，我们也可平安通过，更何况我们有武器，而且人多势众。对我来说，这次遇险，是我一生中最可怕的一次。当时，我看到三百多个恶魔般的畜牲嚎叫着向我们冲来，张开大嘴恨不得一口把我们吞掉，而我们又无处可躲，无处可退，我以为一定完蛋了。

The following points are emphasized:The operation models of adiabatic and diabatic distillation have been set up and the operation block, thermodynamics model and mathematical model in the simulation have been determined as well;(2)Based on the simulation and exergy analysis with Aspen Plus program, shortcut distillation design—DSTWU model and rigorous distillation design—RADFRAC model, the author has determined the heat duty, exergy losses and the distribution of exergy losses along the adiabatic column, which will help the simulation and optimization of the diabatic distillation;(3)Diabatic distillation under various operation conditions has been simulated by using energy balance method and exergy analysis;(4)How the different mixture and the various degree of separation, number of trays and feed location influence exergy saving in diabatic distillation have also been discussed;(5)On the basis of the total exergy losses along the column, different schema of the heat transfer distribution along the column have been compared and analyzed;they can be classified in three categories: heat duty equipartition approach, empirical approach, separation degree matching approach. In conclusion, different heat transfer distribution along the column will have effect on total exergy losses. In particular, most satisfactory results have been obtained by using separation degree matching approach. In order to diminish the exergy losses, heat transfer distribution should meet the needs of the request of separation degree.And on this premise, the author makes his suggestion in increasing the proportion of heat supplied to the tray with minimum exergy losses and decreasing the proportion of heat supplied to the tray with the maximum exergy losses.

本文对透热精馏过程进行了模拟并对其节能效果的影响因素做了较为全面的分析和深入的研究，主要研究内容如下：(1)建立了常规精馏和透热精馏过程的模拟操作模块、热力学模型以及数学模型；(2)利用化工模拟软件Aspen Plus并分别采用DSTWU简捷模型和RADFRAC严格计算模型对常规精馏进行模拟计算和有效能分析，确定常规精馏塔的公用工程热负荷、有效能损失及有效能损失在塔内的分布，为透热精馏的模拟和优化提供数据参考；(3)对不同物系在不同分离度条件下进行透热精馏的模拟，分别采用能量衡算法和有效能分析法进行计算和分析；(4)探讨了各种因素如物系的选择、不同分离度、塔板数、进料位置对透热精馏节能效果的影响；(5)以全塔总有效能损失为比较基准，对热量在塔内的三种分布方案即热负荷平均分配法、经验法和分离度匹配法进行了对比分析并得出结论：塔内热量的不同分布方案对于全塔总有效能损失会产生影响，其中以分离度匹配法的节能效果最为理想，为减少有效能的损失，应使塔内的热量分布满足各塔板的分离度要求，并在此前提下，尽量减小有效能损失大的塔板的热负荷和增加有效能损失小的塔板的热负荷。

Based on the laser longitudinal mode splitting theory, a novel scheme of dual-frequency laser with large frequency-difference is presented using electrically controlled birefringence of liquid crystal, and the transmitted resonant mode splitting by birefringent of Fabry-Perot etalon has been analyzed theoretically. A new element of liquid crystal Fabry-Perot etalon is designed and fabricated, which serves as aselector and splitter of both laser longitudinal modes and Fabry-Perot etalons transmitted resonant modes. Two different experimental systems of laser-diode end-pumped Nd:YAG laser have been set up using two different LDs, and the transmission of liquid-crystal cell have been measured. When the empty LCFP is inserted in the cavity of high-power LD pumped Nd:YAG laser, the oscillation of a single laser longitudinal mode have been observed, such a result shows that the designed and fabricated LCFP element is capable of selecting single axial mode. While an anti-reflected liquid crystal cell is inserted in the cavity of Nd:YAG laser end-pumped by the high-power LD, it is difficult to confirm weather the laser longitudinal modes have been spitted or not. The subject is summarized in this thesis and the improvement of the project has been presented.

If there have been those who doubted whether a confederated representative democracy were a government competent to the wise and orderly management of the common concerns of a mighty nation, those doubts have been dispelled; if there have been projects of partial confederacies to be erected upon the ruins of the Union, they have been scattered to the winds; if there have been dangerous attachments to one foreign nation and antipathies against another, they have been extinguished.

I have been in all my Circumstances a Memento to those who are touch'd with the general Plague of Mankind, whence, for ought I know, one half of their Miseries flow; I mean, that of not being satisfy'd with the Station wherein God and Nature has plac'd them; for not to look back upon my primitive Condition, and the excellent Advice of my Father, the Opposition to which, was, as I may call it, my ORIGINAL SIN; my subsequent Mistakes of the same kind had been the Means of my coming into this miserable Condition; for had that Providence, which so happily had seated me at the Brasils, as a Planter, bless'd me with confin'd Desires, and I could have been contented to have gone on gradually, I might have been by this Time; I mean, in the Time of my being in this Island, one of the most considerable Planters in the Brasils, nay, I am perswaded, that by the Improvements I had made, in that little Time I liv'd there, and the Encrease I should probably have made, if I had stay'd, I might have been worth an hundred thousand Moydors; and what Business had I to leave a settled Fortune, a well stock'd Plantation, improving and encreasing, to turn Supra-Cargo to Guinea, to fetch Negroes; when Patience and Time would have so encreas'd our Stock at Home, that we could have bought them at our own Door, from those whose Business it was to fetch them; and though it had cost us something more, yet the Difference of that Price was by no Means worth saving, at so great a Hazard.

一般人往往有一种通病，那就是不知足，老是不满于上帝和大自然对他们的安排。现在我认识到，他们的种种苦难，至少有一半是由于不知足这种毛病造成的。患有这种病的人大可以从我的一生经历中得到教训。就拿我自己来说吧，正是由于我不满自己原来的境况，又不听父亲的忠告--我认为，我有悖教训，实为我的&原罪&，再加上我后来又犯了同样的错误，才使自己落到今天这样悲惨的地步。当时，造物主已安排我在巴西做了种植园主。如果我自己不痴心妄想发财，而是满足于逐渐致富，这时候我也许已成了巴西数一数二的种植园主了，而现在我却白白地在这荒岛上流落了这么多年，过着悲惨孤寂的生活。而且，我在巴西经营时间不长；就是在这段短短的时间里，我也获利不少。因此我确信，要是我继续经营下去的话，到现在一定拥有十几万葡萄牙金币的家财了。当时，我的种植园已走上了轨道，并且日益兴旺。可是，我偏偏把这一切丢弃，甘愿去当一名船上的管货员，只是为了到几内亚去贩卖黑奴。现在想来，我为什么要这样做呢？要是我守住家业，只要有耐心，经过一段时间之后，同样可以积聚大笔财富，我不是也可以在自己的家门口，从那些黑奴贩子手里买到黑奴吗？虽说价钱贵一点，但这点差价绝不值得自己去冒这样大的风险！
