Based on researchful results of two former students, we take the influences of thermochemistry reaction, mutual disturb and unsymmetrical instance into account. Secondly, the paper simulates the transient thermal response of projectile according to the simulation software, and discuss the ablation regulation when the projectile is in different initial velocity, in different shape, in different angle of attack condition and in different material condition. Thirdly, the effect on the aerodynamic characteristic and the outer ballistic characteristic after the ablation of hypersonic projectile has been analyzed.

在前面两位师兄研究成果的基础上，研究了超高速弹箭组合体在考虑热化学反应、存在攻角影响下的的气动加烧蚀数学模型；然后对不同条件下的烧蚀过程进行计算，分析和总结出在不同外形和不同材料条件下弹体和弹翼的烧蚀规律；紧接着分析了在不同的烧蚀情况下，它对飞行中弹箭的气动力和外弹道特性的影响，从而为今后的超高速弹箭设计提供指导和帮助。

In this paper,the truncated error of trapezium methodis analyzed under ideal state of electrical power parameters,a sin function,when sampling digital measurement and the relationship between the error and the amount of sampling points is offered.

对电力参数的理想情况采样数字化测量的典型算法的截断误差进行了分析，给出了误差与采样点数的关系；根据国家关于电能质量和公用电网谐波的标准规定，对非正弦状态下的误差也做出了符合实际的估计；在电网正常情况下截断误差与采样点数的关系与理想波形时相同。

The power of assembling and dismissing the legislative, placed in the executive, gives not the executive a superiority over it, but is a fiduciary trust placed in him, for the safety of the people, in a case where the uncertainty and variableness of human affairs could not bear a steady fixed rule: for it not being possible, that the first framers of the government should, by any foresight, be so much masters of future events, as to be able to prefix so just periods of return and duration to the assemblies of the legislative, in all times to come, that might exactly answer all the exigencies of the commonwealth; the best remedy could be found for this defect, was to trust this to the prudence of one who was always to be present, and whose business it was to watch over the public good.

召集和解散立法机构的权力，虽然交予执行权力，却并未授予执行权力一种高于立法机构的权力，而是一个为了人们的安全而将信任交给他的受托人，在人类事物不确定和易变的情况下，是不适宜一套稳定固化的规则的：因为政府的最初创建者不可能通过任何远见而成为如此多的未来事件的主人，从而能够恰好预定立法机构集会的时间和期限，在所有的时间到来，又正好能够解决共同体的所有紧急情况；对这种缺陷的最好的补救方法，是将这种情况交托给那个常在的人的审慎来决定，并且他的事务就是看管公共利益。

In floating drilling, such an emergency can occur when the wellsite has to be abandonedbecause of threatening weather, On land, shearing may be the last resort in case of a blowout through the drillpipe.

在浮式钻井中，当钻井工地由于恶劣天气被迫放弃时可能发生此类应急情况。在陆地上，在钻杆爆裂的情况下，切变可能是最后的招数了

Under natural environmental condition, the achenes of Arternisia sphaerocephala and Artemisia arenaria were treated with different electric intensity, to probe the variation of achene weight when the mucilaginous layer holds sand particles, the hydration and dehydration of the achenes, and the germination situation of mucilage-intact achenes and mucilage-free achenes.

用不同强度的电场处理沙生植物白沙蒿和沙蒿果实，在自然环境下研究电场作用后粘液物质将沙粒粘附于瘦果周围后瘦果重量的变化情况、果实水合与脱水情况、粘液果实及剔除粘液层的果实萌发情况。

Furthermore, the light and heat stability of carminic acid was studied, and the results showed that carminic acid was stable under the darkness and the scattered rays of indoor, but it was unstable in the sunshine and the incandescent lamp, its aqueous solution was stable even at lower than 90

此外，对胭脂红酸的热、光稳定性进行研究的结果表明：胭脂红酸在遮光和室内散射光的情况下是稳定的，在白炽灯下不稳定，在阳光下极不稳定；在90℃以下胭脂红酸溶液是稳定的。

The removal of these impurities by three kinds of active carbon(coaly activated carbon,fruit hull activated carbon,woodiness activated carbon) are studied under different experimental conditions.The results show that the fruit hull active carbon is not suitable for the removal of the impurity in bittern of salt lake because its removing rate of COD and turbidity is ...

以去除盐湖卤水中COD和浊度为目的，选用煤质活性炭、果壳活性炭、木质活性炭3种不同活性炭进行净化除杂的工艺研究，结果表明：果壳活性炭对COD和浊度的去除率最低，加入量最大，不宜选用；木质活性炭在低温下(≤20℃)脱除COD效果较好，在常温下(28~45℃)去除COD和浊度的效率明显低于煤质活性炭；在震荡速度、吸附时间及吸附剂加入量均相同的情况下，煤质活性炭脱色除杂效果明显优于其余两种活性炭，在盐湖卤水的脱色净化工程中应优先选用。

利用膨胀法在Thermecmastor-Z型热/力模拟试验机上进行实验室实验，测定了研究钢种在不同的中间保温工艺及一定变形工艺条件下的过冷奥氏体连续冷却转变曲线；对每个试样进行了打磨、抛光、腐蚀，在光学显微镜下观察其组织，研究了在不同中间保温工艺下组织的变化情况；利用所建立的CCT曲线研究了一定变形工艺条件及不同保温工艺对其相变行为及组织的影响，对其影响规律进行了分析。

There exists the principal-agent relationship between stockholders and managers,which takes on different patterns under different conditions:under the condition of symmetric information,it displays as order-subordinate rela- tion ship,which need not incite managers while stockholders can pay managers regular fee by contract;under the con- dition of dissymmetric information,it displays as a fellowship,which need incite managers because managers may per- form according to the payment.

股东和经营管理者之间存在委托代理关系，这种委托代理关系在不同情况下具有不同的表现形式：在信息对称条件下，表现为命令和服从关系，此时无需对经营管理者进行激励，股东以&强制合同&的形式支付给经营管理者确定的报酬即可；在信息非对称条件下，委托代理关系表现为合伙关系，对经营管理者的激励相当重要，因为经营管理者会根据激励强度来付出劳动。

The range of bacteria that could be effectively detected corresponded to about 10^4 to 5×10^5 cells/mL. Results obtained, using a medium with toluic acid as the sole carbon source, indicated that in soil either with, or without, the addition of toluene, P. putida D8 could not be recovered, 288 and 72 hours after inoculation, using classical growth-dependent culture techniques.

根据传统之平板培养法，利用toluic acid为唯一碳源之选择培养基，侦测Pseudomonas putida D8在土壤中之消长情形，结果显示在有添加甲苯之状况下到188小时后方才无法测得目标菌株；反之，在没有添加甲苯的情况下，48小时后便已无法测得。
