在...的控制下

The bulky ortho-brominated aryl groups are implanted to create nonplanarity around amino center. Thus, the effective conjugation length to the protonation site is shortened and the energy gap between neutral and protonated forms is narrowed. The protonation can only occur at the nitrogen atom of the benzothiazole and the temperature variation disturbs the equilibrium between the neutral and monocation and the reverible thermochromic effect can thus be achieved.

在邻位的位置引入立体阻碍大的溴原子，进而控制质子化过程的酸碱平衡只发生在 benzothiazole 上的氮原子上，企图达到只有中性分子，与单阳离子两种稳定的形式存在，经由外界的刺激下，例如温度或酸的量的改变，促使逆反应的发生，而达到热致变色的效果。

A recovery system of manufacturing/remanufacturing for multiple products was investigated. Backlogging was granted with dynamic demands and returned rates. An optimal model was established by minimum total costs in a finite planning horizon, which was resolved by the Pontryagin's maximum principle.

针对多产品的生产／再生产混合系统的逆向物流库存控制问题，在假定允许缺货、需求和回收均为动态的情况下，建立有限时间域内总成本最小的优化模型。

If push comes to shove, buy-out funds could inject some of their "dry powder" to pay down debt—providing the conflicts of interest between new and old investors could be managed.

如果由单个偿付变成了多家挤兑，在可以控制好新老投资者的利息偿付冲突的情况下，收购基金可以注入一些他们的"干粉"(筹集到但是还没有用的钱)现金支付债务。

Basing on the variation principle of solid-fluid coupled problem,on the situation of the tank being full filled,the essential method and principle have been found by using the numerical approximation of finite element method.

在罐车满载的情况下，根据固液耦合问题的广义变分原理，使用有限元的近似数值计算方法，找到解决满载罐车液固耦合振动问题的基本方法和原理，建立铁路罐车的固液耦合问题的动力学控制方程，并通过算例验证液体对罐车耦合振动的影响，得到在工程上所需要的分析结果。

In Germany two-thirds of the Masons are members of the old Prussian Grand Lodges under the protectorship of a member of the Royal Dynasty, which implies a severe control of all lodge activity in conformity with the aims of the Government.

在德国三分之二的共济会成员旧的普鲁士大旅馆protectorship下一个成员王朝，这意味著严重的控制提出的所有活动符合目标的政府。

This paper takes one low-speed-circumgyrate rocket with a empennage asa research object, set up a relevant reference frame, analyse the strength andmoment on the amended rocket, ratiocinate the sports equation with 6 DOF; analyse the factors which cause terminal windage between pratical trajectoryand fiducial trajectory, take certain rocket for example, make use of theemluator on the influence of estimating precision caused by measuredinformation, find the speed, the trajectory obliquity, the trajectory setoverand the coordinate are the sensitive factor arosing terminal windage of thetrajectory; introduce the developing status of detecting technique, and basedon the actuality, choose the radar in the ground as measure equipment; simplydesign and analyse the setting and inflame control of the impulse engine onthe amended rocket; design the amend method and validate its feasibility takingthe use of emluator.

本文以某型低速旋转尾翼火箭弹为研究对象，建立了相应的坐标系，详细的分析了作用在弹道修正弹上的力和力矩，由动量定理和动量矩定理推导出了在一般形式下的弹道修正弹的空间六自由度的运动方程；对引起弹道落点偏差的因素进行了分析，以某口径火箭弹为例仿真了可测信息量对估算精度的影响，发现速度大小、弹道倾角、弹道偏角和位置坐标是引起落点偏差的主要因素；对弹道探测技术发展现状作综合性阐述，并基于现状，选用地面火控雷达作为测量装置；对弹道修正弹上脉冲推力器的安装和点火控制方法进行了简要的设计与分析；设计了弹道修正弹指令修正的修正方法，通过数字仿真验证了方法的可行性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
