Special solutions for the ring circular domain with crack surfaces acted on uniform compressive force, linear compressive force and linear shearing force are deduced in polar coordinate employed the eigenfunction expansion technique in the Hamiltonian system of elastic mechanics. Combined with the general solution for the above problems, the analytical solutions for crack tip fields with surfaces acted on the above three kinds of loads are obtained. These solutions offer theoretical basis to construct analytical elements for plastic analysis of crack.

从弹性力学哈密顿体系理论出发，利用平面弹性力学极坐标系下的本征向量展开求解，推导了环形圆形域裂纹边作用有均布压力、线性压力和均布剪切力情况下的特解，从而得到了裂纹表面作用有以上三种荷载情况下的裂纹尖端场的解析解，为进一步构造进行弹塑性裂纹分析的奇异解析元奠定了理论基础。

The results from the study on the decoloring conditions of strain 3# showed that the pH range for decoloring reaction was 5～11 with 6 ～7 being the optimum, the temperature range was 10～30℃ with 30℃ being efficiency optimal. The decoloring efficiency was higher under the presence of oxygen than that lack of oxygen. Strain 3# could more strongly decolor malachite green under optimum conditions. The decoloring rate was above 50%, 70% and 90% in 4, 12 and 24 h treatment, respectively.

对3#菌株的脱色反应条件进行初步研究表明，3#细菌的脱色反应的pH为5～11，最佳范围pH 6～7；温度10～30℃，最佳温度30℃；有氧气情况下的脱色效果较缺氧情况下好；在最佳条件下该菌对孔雀绿染料的脱色作用较强，处理4、12、24 h后，色度去除率分别达到50%以上、70%以上和90%以上。

With the increase of NaCl concentration and prolonging of stress time,the contents of Na in leaves of the untrasgenic plant was more distinct than the transgenic plant,especially under 0.9%NaCl stressed after 40 days, the contents of Na was 2.0-6.2 times compared with the transgenic plant in the same desposition,therefore,the un-transgenic plant died under this concentration in the end .

随着盐浓度的增加和胁迫时间的延长，对照植株叶片中Na 含量极显著地高于转基因植株，特别是在0.9%盐度下胁迫40d，对照植株的Na 含量极高，是该处理下转基因植株的2.0-6.2倍，因此，该浓度下的对照植株最终死亡。

By calculating the equivalent loading,the process of strength degradation under random loading was transformed into a process under the deterministic loading,and the relationship between reliability andtimes of loading action was obtained.Besides,the time-dependent reliability models under multi-loadings were established by analyzing the relationship between action times of different loadings and time.

该模型通过计算当量载荷，将随机载荷作用下的强度退化过程等效为确定性载荷作用下的退化过程，得到零件可靠度与载荷作用次数的关系，在此基础上，通过分析不同载荷出现次数与时间的关系，得到多个载荷共同作用下零件可靠度随时间的变化规律。

Following such study clue, I gradually introduced the factors that should be taken into account in discretionary disclosure and integrated all the theories in a frame. Firstly, I introduced the concept of "proprietary cost" and analyzed the level and strategies of disclosure which were taken by firms.

本文按照逐步引入影响因素的方法将现有的理论串成一线：首先引入"专有性成本"这一因素，分析了专有性成本理论框架下公司选择性披露水平及决策问题；在此基础上，引入了产品市场竞争因素，分析了不同产品市场竞争环境下公司的选择性披露决策；接着，笔者又将金融市场竞争因素引入，解释了为什么上市公司事实上并非完全遵循产品市场竞争环境下的披露策略，而会出现披露的"羊群行为"。

Sometimes whoever seeks abroad may find Thee sitting careless on a granary floor, Thy hair soft-lifted by the winnowing wind; Or on a half-reap'd furrow sound asleep, Drowsed with the fume of poppies, while thy hook Spares the next swath and all its twined flowers: And sometimes like a gleaner thou dost keep Steady thy laden head across a brook; Or by a cider-press, with patient look, Thou watchest the last oozings, hours by hours.

在田野里也可以把你找到，弥有时随意坐在打麦场上，让发丝随着簸谷的风轻飘；有时候，为罂粟花香所沉迷，你倒卧在收割一半的田垄，让镰刀歇在下一畦的花旁；或者。像拾穗人越过小溪，你昂首背着谷袋，投下倒影，或者就在榨果架下坐几点钟，你耐心地瞧着徐徐滴下的酒浆。
