平衡法

A modified backward Euler method is developed which enables to increase considerably the accuracy of jump voltage computation as a result of freeing its computing from the influence of the faint asymmetrical initial current in such an inductive circuit as converter and completely eliminate numerical oscillation in converter simulation as often seen in the case of implicit trapezoidal integration method.

本文提出一种变形的后退欧拉法，用该法对换流器这样的纯电感电路进行跃变电压计算，可完全避免初始电流中微弱的不平衡对跃变电压计算的影响，大大提高了跃变电压的计算精度，并彻底消除了隐式梯形积公法用于换流器仿真时所存在的非原型数值振荡。

The tort liability caused by throwing objects from the building when the inflicter is uncertaine is ultimately a problem of how to balance risks and benefits, which is beyond the tort law. So it's a better choice to relieve victims through social security and commercial insurance.

加害人不明的建筑物抛掷物责任，归根结底是一个分散风险与利益平衡的问题，超出了侵权法的调整范畴，对受害人的救济，可通过社会保障和商业保险等立法政策予以调整和实现。

Finally,this paper discusses the problems of neutral point control that exists in the three-level inverter, and adopts two methods to control neutral voltage balance namely judging power direction and detecting instantaneous current value.

最后论文还对多电平逆变器存在的中点电位漂移问题进行了讨论，并采用两种方法来实现中点电压平衡，即判别逆变器功率流向法和检测瞬时电流值方法。

It is pointed out that the adaptive controller based on Lyapunov stability theory completes the integration of the square term caused by the integration of the multiplication term, and the integration of the square term is exactly the source of the slow-drift and its instability.

本文用均值平衡位置内摄动分析法，分析了有正态零均值噪音及有未建模动态时MRAC 的慢漂移。指出用Ляцунов稳定性理论或超稳定性理论设计的自适应控制器中，完成相乘项和平方项的积分，是MRAC慢漂移及慢漂移不稳定的根源。

The key to good tone with a pucker embouchure is the same as with a tongue block - the right balance of tension and relaxation, a nice big resonant cavity in the mouth, good breath control and careful attention to the sound you are producing.

事实上，得到优美音色的关键，无论使用单孔还是舌堵法都是一样的：在紧张和放松之间找到正确的平衡，在口腔中保持良好的共鸣腔，有效控制自己的气息并且注意你吹奏出的声音。

In terms of continuum mechanics and nonequilibrium irreversible thermodynamics theories, compressible Leonov constitutive model is derived to describe large recoverable elastic strain development in non-isothermal flow of compressible viscoelastic melts. It is tempting to specify the model and then compare it to basic rheological tests in the hope that such a model will yield a good description of the nonlinear viscoelasticity of polymer melts.

注射成型是聚合物的主要成型加工方法之一，成型过程中聚合物要经历熔体流动和固化等非等温、非平衡过程，由于聚合物的粘弹性，流动过程中建立的剪切应力、法向应力和大弹性形变在固化过程中不能完全松弛，在制品中形成残余应力和取向，对制品的机械和光学性能有着重要影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
