Simulation results show that it can improve the systems performance with low torque ripple, using the null vector rationally.

仿真结果表明，正确地使用零电压矢量能够有效减少转矩脉动，改善系统性能。

As she is such a numskull anyway; so she got a lot of them out and brought them in last night and put them in my bed to keep warm, but I have noticed them now and then all day, and I don't see that they are any happier there than they were before, only quieter.

昨晚，她从池塘里面捞回很多鱼，还要我把这些鱼弄进屋子，放在床上帮它们取暖。可是，据我观察，它们在床上好象并不比在水中时快乐。它们只是静静地躺在那里，一动也不动。

Simulation and test prove that this method can improve nutation stability caused by gyroscopic effects effectively.

仿真和实验结果表明，采用这种基于转速的增益预调交叉反馈的控制算法，能够有效地抑制磁悬浮飞轮转子陀螺效应所导致的章动失稳，所设计的磁悬浮飞轮原理样机能够稳定运行在其额定转速30000r／min。

In order to improve the amplitudes of the rigid Earth nutation series, it become necessary to revise the IAU 1976 value of the general precession in longitude.

非刚体地球章动的转换函数中所采用的简正模频率和常数都直接或间接地依赖地球动力学扁率值。

The order contact of skeleton is similar to that of common traffic and is suitable to be kept between 1.07 and 1.15. When adopting dynamic stability index to evaluate the high temperature performance of asphalt mixture, it is likely to stretch the work of modified asphalt and there is a discrepancy between the capacity to evaluate different gradation designs and the practical facts. In the late process of creep, stiffness module index can evaluate the high temperature performance of asphalt mixture which is relatively objective. The rutting prediction model based on this is relatively reliable.

采用车辙动稳定度指标评价沥青混合料高温性能时，可能夸大了改性沥青的作用，其对不同级配优劣的鉴别能力与实践事实间也存在一定的差异，而蠕变劲度模量指标能够较为客观地评价沥青混合料的高温稳定性能，且在此基础上建立的车辙预估模型经实践检验具有较高的可靠性。

The material job and main conclusion are as follows:(1) A simple boundary orthogonalization procedure independence grids generation method is put forward on the base of algebraic grid generation method; Data structure and computational model on interface are established aiming at blocks of structured grids.

本文针对粘流场数值模拟技术的研究现状和发展动态作了比较全面的回顾与展望，重点研究了网格生成技术、数值求解技术、湍流模型技术和动边界模拟技术，在此基础上建立了模拟自由面湍流场的数学模型，并成功地应用到二维溢流坝和带闸墩的三维溢流坝过坝水流的数值计算。

They always palpitate in heart, and for the sorrow in their heart they cannot do anything.

偶尔能看见那样不停地寻找和追求的人，因为总想看更多。心中总是产生悸动。

It is obviously clear that we feel our hearts palpitate under the sky of Taipei, untied from the ancient bondage in the bottom of our hearts, and embrace the world in our arms.

我们这一群在民国八十四年前后，不约而同地像顿悟一般，解放了心中那太过古老的束缚，企图找到一个我在我属我动我想拥抱的世界。

Suddenly, he saw a hare from the adjacent grass sprang a panic, the one hit the child on Tanabe's stump, then down there in a motionless.

突然，他看见有一只野兔从旁边的草丛里慌慌张张地窜出来，一头撞在田边的树墩子上，便倒在那儿一动也不动了。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
