On the basis of the kinetic equation of substrate reaction in the presence of urea or guanidine hydrochloride, all microscopic kinetic constants for the free enzyme and enzyme-substrate binary and ternary complexes have been determined. The results of the present studies indicate that:①In the presence of urea or guanidine hydrochloride, enzyme-substrate complexes lose their activity less rapidly than the free enzyme. Therefore, both substrates, NADPH and 7, 8-dihydrofolate, protect dihydrofolate reductase against inactivation.②The denaturation of dihydrofolate reductase by urea follows single-phase kinetics, and changes in enzyme activity and tertiary structure proceed simultaneously in the unfolding process, so it may be an"all or none"process.③The GdnHCl-induced unfolding of the dihydrofolate shows a biphasic transition, while the change in the enzyme activity is a single exponential process. The rate constant of inactivation is consistent with that of the fast conformational change. Therefore, the kinetic intermediate of protein unfolding should be a partially folded and inactive form.

我们根据在脲或盐酸胍存在下的底物反应动力学方程求得游离酶和酶底物二元、三元复合物的微观动力学常数，结果表明：①酶-底物二元、三元复合物的失活速度明显慢于游离酶，说明两个底物二氢叶酸和NADPH对酶的失活都具有一定程度的保护作用；②在脲作用下，酶的失活和构象变化均为单指数项过程，而且酶的活力丧失和三级结构变化是同时发生的，说明二氢叶酸还原酶的脲变性可能是一个"全或无"的两态过程；③在盐酸胍作用下，酶的构象变化为两相过程，而失活则是单指数项过程，酶分子构象变化的快相速度常数与失活速度常数基本一致，因此我们认为二氢叶酸还原酶的盐酸胍变性过程中存在一个没有活力、但仍具备一定空间结构的变性中间体。

Chu presented a Multicast Watermark Protocol, however, did not provide the schemes by which the fingerprint can be coded, so from the theoretical point of view, there does not exist the foundation for leaker identification and being collusion free, Furthermore, from the practical point of view, MWP cannot identify the leaker and be collusion free in the case of smaller amount of raw data.

Chu提出了一个多播水印协议MWP ，但没有研究如何进行指纹编码，因此在识别泄漏者、抵御合谋攻击方面缺乏理论依据，并且从实践的角度看，在原始数据量较小的情况下，MWP不能识别泄漏者，也不能抵御合谋攻击。

According to the effect of relative permittivity εr on the pulse propagation velocity in lossy dielectric space and the effect on the turnround time of signal between the antenna and the buried objects, it is presented that lossy dielectric space can be transformed into free space and the simulation results abtained from free space can also be amended to lossy dielectric space.

对探地雷达的微波全息成像法进行了分析研究，根据有耗介质空间中的εr 对脉冲传播速度的影响，以及对脉冲在收发天线与目标之间的往返时间的影响指出：可将有耗介质空间转化到自由空间，再将自由空间中的计算结果修正到有耗介质空间。

In order to further support the export of domestically made cigarettes, and meanwhile continue strengthening the administration of taxation on exported cigarettes, the State Taxation Administration has, upon deliberation, decided to increase the outer-port customs (that is, the representative office in Shanghai Waigaoqiao Port) under Shanghai Customs and Haicang Representative Office under Amoy Customs as the ports for export of duty-free cigarettes, meanwhile, for the exported cigarettes, if the customs declaration form on the exported goods supplied to Shanghai Ocean Ship Chandler Company within the plan of duty-free exported cigarettes is affixed with a seal of "being inspected by Shanghai Customs", they are permitted to be exempted from duty and be written off after verification.

为进一步支持国产卷烟出口，同时继续加强出口卷烟的税收管理，经研究，总局决定增列上海海关所属外港海关（即上海外高桥港口办事处）、厦门海关所属海沧办事处为免税卷烟出口口岸；同时准予对在免税出口卷烟计划内供应给上海远洋船舶供应公司的出口货物报关单上加盖"上海海关"验讫章的出口卷烟，予以免税核销。

Free from worries is inspected is the company that home has the first times advertisement cooperates with PPG, both sides signed relevant contract in June 2004, the incoming telegram after PPG looks a man in advertisement in white be opposite before setting board of the shirt deduce, originality of this one advertisement also inspects a design by free from worries, free from worries is inspected still was in charge of PPG a TV advertising pat produce a film to make.

旷视是国内第一家与PPG进行广告合作的公司，双方于2004年6月签订了相关合同，PPG后来电视广告中一位男士在白色背景板前对衬衫的演绎，这一广告创意也是由旷视设计的，旷视还负责了PPG第一则电视广告的拍摄制作。

With the appearance of a free span pipeline, its loading types and stress state will be changed. Especially when ocean currents pass through it, a periodical vortex shedding is often produced and induces vibration of the free span pipeline. This type of vibration contributes a lot to the fatigue failure of a free span pipeline.

管跨段的出现改变了海底管线所承受的载荷形式和应力状态，尤其是在海流作用下流经管跨时，常伴随着周期性的涡旋发放，引发管跨段的周期性振动，成为管跨段发生疲劳失效的主要因素之一。
