逆动

It is to my mind that very consciousness of the production of beauty for beauty's sake which we want to avoid; it is just what is apt to produce affectation and effeminacy amongst the artists and their following.

在解释过我所持的逆潮流而动的悲观主义之后，我还要阐明为什么在我的观念中手工艺从静态的角度上看是必须的，以及为什么其毁灭将会造成生活的贬黜。

E. the method of model reference plus inverse system.

基于动平衡状态的概念，本文还提出了一种将模型参考控制系统中模型输出与对象输出同时偏置，以实现无差控制的方法：模型参考逆系统方法。

In fault-developed block or in complicated overthrust structural area ,the strata being of various interval velocities may be in touch with each other or the same strata appear many times at the faults because of these factors as fault offset and formation fold, etc.

在断裂发育的断块区或复杂的逆掩构造区，由於断层错动及地层褶皱等因素，具有不同速度特徵的地层在断层处相互接触或同一套地层多次重复。

The ability of tracking the reference signal and restraining the parameter perturbation and stochastic disturbance are improved.

这种算法克服了广义预测控制中求解逆矩阵的缺点，提高了系统响应的速度，并且具有较强的跟踪给定信号、抑制系统参数摄动和随机噪声的能力。

In the fourth part the algorithm of SVPWM that is adopted by the system implements the motor speed regulation.

第四部分系统采用SVPWM算法减少了逆变器输出电流的谐波，降低了脉动转矩，提高了电压的利用率。

Afterwards, a novel control strategy is put forward. A Swept-frequency with separate and self-excitation switching is applied in starting circuit, which can look for resonant point automatically.

然后，提出一种新型的逆变控制策略，启动电路采用扫频方式自动找寻负载谐振工作点；工作状态控制采用锁相环技术和重叠角随动控制相结合的方法。

In this thesis, the methods for solving eigenvalue problems and conventional reanalysis methods are studied firstly. Then, a new reanalysis method for real modal reanalysis of structures subjected to topological modification with added degrees of freedom is presented. This method is composed of the single step perturbation method and the Rayleigh-quotient iteration. The numerical examples show that this reanalysis method is very effective and high-quality.

本文首先在对常规的特征值数值求解方法和重分析方法研究的基础上，针对实模态的自由度增加的结构拓扑修改重分析，提出了一种新方法，该方法由于结合了单步摄动法和瑞利商逆迭代法两者的优点，应当是一种比较理想的重分析方法，算例的数值结果也有力的验证了该方法确实是一种高精度、十分有效的实模态重分析方法。

And just as well, the ruined beacon was a day's swim away, even with the tide on his heels.

而且好在即使逆潮而动，游到灯塔废墟也只需要一天。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
