It is of importance to capture the extreme value distribution of dynamic stochastic response of structures for reliability evaluation of engineering structures.

1引言 在工程实践中，结构的参数或激励往往具有很强的随机性，因而导致结构动力响应是一个随机过程，这使得有效地把握结构的动力反应特别是非线性动力反应和结构动力可靠度迄今为止仍是相当困难的课题t'，'〕。

In this technique, K-L transformation was used to remove spectral statistic correlation on the spectral direction. Then SNMAW prediction tree technique was used to remove spatial correlation and spectral structure correlation. With the limit of a certain max error, this technique can get a higher compression ratio. 6. We proposed a lossy compression technique based on wavelet transformation with sharing significance map.

该方法在谱维方向进行K-L变换，有效地去除谱间统计冗余，而变换后的图象仍存在空间相关性和谱间结构相关性，再利用改进的预测树方法方法进行无损压缩，在最大误差很小的限制下，得到较高的压缩效率。

In recent years,with the development of high technology,the systematical plan of high-precision stereotactic surgery and the highfield MRI have been gradually applied in clinical trial.What\'s more,the target localization becomes more precise with the constant development of radio-frequency technique.Therefore,Psychosurgery has become an effective method of treatment for the intractable psychopathy,with an obviously improving curative effect and less harm caused by the surgery to the patients.

近年来，随着科技的发展，高精度立体定向手术计划系统和高磁场MRI逐步应用于临床，射频技术也不断提高，对靶点的定位更加准确，手术疗效明显提高，手术对患者造成的损害越来越小，该手术方法已成为难治性精神病的一种有效治疗手段，但远期疗效仍有待于进一步观察，且近年来各种争议越来越大，值得临床进一步研究。

The steady factors of the emulsion in water were studied ,and find that its stability is hardly influenced because of different quantity scores (1 000-5 000 mg/L)of the salt and different rigidness (0-500 mg/L)water.When the quantity of the Metolachlor increased by 40%, the stability of EW is still kept in good .

并通过对异丙甲草胺水乳剂稳定性影响因素的研究，发现不同含盐量(1 000~5 000 mg/L)和不同硬度(0~500 mg/L)的水对制剂的稳定性几乎无影响，有效成分含量增至40%时，制剂仍表现出较好的稳定性。

Subject always to the goods being in sound condition at the time of attachment, this insurance covers, except as provided in Clause 4,5,6, and 7 below, loss of, deterioration of, or damage to the subject-matter insured which shall arise during the currency of this insurance.

本保险承保除了下述第4，5，6和7条规定者外的，在本保险有效期间发生的保险标的的灭失、腐坏变质或损害，但仍须受货物在本保险责任开始当时处于良好状态的限制。

The result is that the quantity of THMs is reduced availably, however a little TOX is still produced which required further study.

研究结果表明，二氧化氯能有效地降低THMs的生成量，但仍有一定量的TOX的产生，有待进一步的研究。

The relevant coefficients of temperature,humidity and rainfall against water consumption are evaluated;and the ARX models for water demand forecast...

此外，在多步长的预测中，考虑气象因子后的预测模型精度仍具有明显的优势，是对用水量自回归时间序列预测方法的有效完善。

Research of microenvironment werefocused on the neurotrophic factors. Many studies have been done to use nerve conduits filled with exogenetic NTFs with the intention of promote axonal regeneration to the greatest extent efficiently. However concentration of exogenetic NTFs and the means of releasing NTFs still need to be studied.

对于后者，研究主要集中在神经营养因子(neurotrophic factors，NTFs)，众多学者尝试将外源性NTFs引入神经导管，以期尽可能有效地促进轴突再生，但外源性NTFs导入的浓度和释放的途径仍需进一步研究，同时最有益于神经再生所必须的营养因子的数量和种类也待进一步明确。

It is beneficial for us to draw lessons of Muckraking in the constructing of new system of news/mass communication fit for China's modernization.

借鉴黑幕揭发运动的经验教训，对于构想和设计中国新闻/大众传播新体制，使之有效担当转型期的社会守望者和社会雷达的角色，在这场运动百年之后仍有不可忽视的价值。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
