In this paper, the basic theory and work principle of cellular automata were introduced concisely. The influence of strain-rate and temperature on the number of nucleation and the mean size of R-grain, as well as the influence of cooling on ultimate microstructure of blade after forging finished off were considered. The microstructure evolution was simulated successful based on the DEFORM-3D. The simulated results agree well with growth kinetics of dynamic recrystallization of classical theory and physical experiment.

As I mentioned earlier, the yearend prices of our major investees were much higher relative to their intrinsic values than theretofore. While those prices may not yet cause nosebleeds, they are clearly vulnerable to a general market decline. A drop in their prices would not disturb us at all - it might in fact work to our eventual benefit - but it would cause at least a one-year reduction in Berkshire's net worth. We think such a reduction is almost certain in at least one of the next three years.

就像是我上次所提到的，相较于过去，我们这些被投资公司的股价已高于其实质价值，虽然目前以这种价位不会造成我们流鼻血，但难免会受到大盘波动的影响，当然股价下挫一点都不会造成我们的困扰，甚至反而对我们有利，但不可避免地可能会造成伯克希尔年度净值的减少，只要在未来的两，三年间，我们的投资组合市值平均每年减少 10%，就有可能会发生这种状况。

For Berkshire's shareholders, myself included, the cost of this thumb-sucking has been huge. o Our consistently-conservative financial policies may appear to have been a mistake, but in my view were not. In retrospect, it is clear that significantly higher, though still conventional, leverage ratios at Berkshire would have produced considerably better returns on equity than the 23.8% we have actually averaged. Even in 1965, perhaps we could have judged there to be a 99% probability that higher leverage would lead to nothing but good. Correspondingly, we might have seen only a 1% chance that some shock factor, external or internal, would cause a conventional debt ratio to produce a result falling somewhere between temporary anguish and default.

另外我们一贯保守财务政策可能也是一种错误，不过就我个人的看法却不认为如此，回想起来，很明显的我们只要能够再多用一点财务杠杆操作(虽然较之他人还是很保守)，就可以得到远比现在每年平均 23.8%还要高的投资报酬率，即使是在 1965 年我们也可以百分之九十九地确定高一点的财务杠杆绝对只有好处没有坏处，但同时我们可能也会有百分之一的机会，不管是从内部或是外部所引发令人异想不到的因素，使得我们负债比率提高到介于一时冲高到负债倒闭之间。

Finally, we measured the performance of our algorithm using 50-200 torii with 800 triangles. The average collision detection time is around 1.3-14 milliseconds. In the experiments, our approach had shown to be efficient for collision detection in physics simulation and applied to real-time applications.

最后，我们利用50~200个由800个三角形构成的圆环测试执行效能，平均所花费的碰撞侦测时间约为0.85~9毫秒，实验结果，证实我们的方法能有效率地应用於物理模拟或即时系统之中

Each medicine used in the study totally has obivious effect on lens sodium-pump. Either on the molecular and cellular level or on the histological and organic level , they all have their distinctive demonstration. 1.Ouabain、Digoxine、DMSO decrease the expression of αsubunit of sodium pump on mRNA level , the cell morphology and ultramicroscopic structure demonstrated destructive effect,it indicates the cause of cataract of the medicines.2.D-thyroxine、Amphotericin B、Vitamin E increase the expression of αsubunit of sodium pump on mRNA level ,from the demonstration of the cell morphology and ultramicroscopic structure ,it indicates the medicines have protective or anti-distructive effect on lens.3.The medicines have isoform-specific action on lens sodium-pump,it indicates exploitting isoform-specific medicine has a promising clinical application.4. Lens sodium-pumps are inhibited probably lead to cataract, so in clinical medication, especially to the cardiovascular doctor, while he is using the sodium-pump inhibitors, he should pay more attention to adjust the dosage and duration of the drug therapy. 5. To creat the animal model of cataract through inhibiting lens sodium-pump, whether it can be a kind of classical method or not, it is worthy of further research.

本研究所选用的药物对晶状体钠泵均有明显的影响作用，在分子水平、细胞水平、组织器官水平均有特异的表现：1、哇巴因、地高辛、二甲基亚砜三种药物可降低晶状体钠泵α亚单位在 mRNA水平的表达，在细胞形态和超微结构上表现为损伤效应，提示了其潜在的导致白内障的可能。2、D甲状腺素、两性霉素B、维生素 E三种药物可升高晶状体钠泵α亚单位在 mRNA水平的表达，从细胞形态和超微结构上的表现，提示了其对晶状体有保护作用或抗损伤效应。3、药物作用于晶状体钠泵具有重整异构特异性，提示了开发出特异的具有重整异构作用的药物是极有临床应用前景的。4晶状体钠泵抑制后可能导致白内障的发生，故临床用药，尤其是心内科医生在使用这些钠泵抑制剂时应注意调整用药剂量及药物疗程。5 通过抑制晶状体钠泵来制作白内障动物模型能否成为一种经典的制作方法，还有待于进一步研究。
