The track estimating theory is applied to the analytical processes of hopping in the several typical environments: hop over planar surface, overleap obstacles and ditches, jump up steps or jump down.

把轨迹预测理论应用于水平地面跳跃、跃过沟渠、跨越障碍物、跃上或跃下台阶等几种典型地形下跳跃过程的分析中。

In particularization KIBS firms, the levels of self-leadership and boundary penetrability are positive related with innovation performance, but just self-leadership degree is related with innovation performance when it happens in standardistion KIBS.

在定制化KIBS企业背景下，结构的自我管理性和边界渗透性对创新绩效具有显著影响，创新组织表现为高度自我管理与边界渗透的结构特征；而在标准化KIBS企业背景下，仅自我管理性水平表现出对创新绩效的显著影响。

Nitrate-N content in 0~60cm soil profile with intercropped faba bean and pea are lower than the monocrops under zero N application and 225kghm^(-2) N application; while that with soybean lower than the monocrop at zero N application, but higher at 225kghm^(-2) N application.

玉米收获期，不施氮条件下3种豆科作物间作0~60cm土壤硝态氮含量均低于单作；225kghm^(-2)氮水平下，蚕豆、豌豆间作0~60cm土壤硝态氮含量低于单作，而间作大豆0~100cm土壤硝态氮含量高于单作。

Surface of plate face was very smooth, unlike rough, pebbly surface of cemented plates, such as U.S.

碳含量被增加到了VC钢的水平以使其容易淬火；加入适量的铜以减少镍的使用量；又加入少量的钼以加强淬火的硬化能力；在无须牺牲VC级别防护性能的情况下，没有采用对浅层装甲使用渗碳（大多数情况下外国的表面硬化处理方式）的工艺。

At the same time, a pitot tube is used to measure the dynamic pressure of smoke, with the mixed velocity of water mist a...

通过改变喷头类型和工作压力，研究了不同工况下雾滴速度和粒径等因素对烟气运动速度的影响规律，定量地表征了细水雾作用下烟气在水平方向和垂直方向上速度增量的变化规律，为细水雾灭火系统的优化设计提供了科学依据。

Therefore we must bring the hand into a horizontal position with its palm down; this is done by pronation.

所以我们必须将手掌向下使手掌处于一个水平位置；只要将手掌向下就行了。

However when the upper arm is raised, the ulna and radius will be removed from their extreme position and relieved of tension, and the hand can assume its horizontal position without extreme pronation.

Self-drive car: Drive along Luosha Road from the urban to Yantian, and then drive to Yanba Expressway and drive off at Kuiyong, pass through the DIEFUSHAN tunnel, turn to the horizontal direction at the new interchange after drive down from the slope, and then, drive towards the direction of Dongshan and Yangmeikeng and arrive at the destination.

自驾车：从市区沿罗沙公路到盐田，然后上盐坝高速到葵涌下，往大鹏方向，穿过迭福山遂道，下了斜坡后在布新立交转向水平方向，然后往东山，杨梅坑方向开，即可找到。

In this paper,the behavioral,physiological, ecological adaption mechanism of H.armigera and H.assulta to their common host plant tobacco were studied comparatively,and the main results were summarized as follows:Electroantennogram response of adult to tobacco volatiles:(1) H.armigera and H.assulta elicited similar EAG responses to the tested 20 tobacco volatiles;both of them elicited significantly more sensitive to green leaf volatiles,aliphatic and aromatic compounds, than to monoterpene,sesquiterpene,heterocyclic compounds under lower concentration; while the similar EAG responses under higher concentration were detected,but most of them were not significantly different with each other.

本文从行为、生理和生态适应三个方面，对棉铃虫和烟夜蛾与烟草间的互作进行了比较研究，主要结果如下：成虫对烟草挥发物的EAG反应：(1)两种夜蛾对测试的20种烟草挥发物均可产生EAG反应；低浓度下对绿叶气味、脂肪族、芳香族化合物的EAG反应显著高于单萜类、倍半萜类和杂环化合物；高浓度下的EAG反应也表现出相似的总体反应趋势，但多数反应值间的差异未达显著水平。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
