逆地

The power electronic technology take the general invertor as representative, widely applies in domains and so on electric car, domestic electric appliances, power equipment, industrial equipment, transportation vehicles.

功率电子技术以通用逆变器为代表，广泛地应用于电动车、家用电器、电力设备、产业设备、交通车辆等领域中。

In actuates the source specially as the equipment in the motor control, can supply the demand through the invertor the voltage and the electric current, but controls the rotational speed and the driving torque freely.

特别在作为设备驱动源的电动机控制中，通过逆变器能够供给需求的电压和电流，可自由地控制转速和驱动转矩。

Conversely, when you play the Law of Diminishing Kicks backwards — when you stop trying to top the last kick and voluntarily turn around to descend through the depths of the nether thrills — something very surprising happens.

相反地，当你顺着边际效益递减规律往后走—当你停止在正常性爱的世界勉励向上一小步，自愿掉转头往逆反的惊悚世界堕落—某些非常惊奇的事情发生了。

This is the so-called Duerlite algorithms: from the bottom row of the matrix A do elementary transformation, the diagonal elements into the bottom left of zero, and then show the effect of these lines is equivalent to transform the left by a unit lower triangular matrix, this series of unit lower triangular matrix inverse is the product of L matrices, it is also a unit lower triangular matrix.

这正是所谓的杜尔里特算法：从下至上地对矩阵A做初等行变换，将对角线左下方的元素变成零，然后再证明这些行变换的效果等同于左乘一系列单位下三角矩阵，这一系列单位下三角矩阵的乘积的逆就是L矩阵，它也是一个单位下三角矩阵。

The accuracy of Helmhotz matrix is raised 10 times than that of spectrum, and the calculation speed is faster than that of the direct solution. In this way, the method can reduce the time of matrix inversion in 3dimensional implicit difference migration and can be used to real data processing.

因此，该方法的提出，在计算精度许可的条件下，最大限度地减少三维隐式差分偏移中矩阵求逆占用的时间，从而使得该方法能真正用于实际地震资料的处理。

As we know,Newton's interpolation polynomial is based on divided differences which can be calculated recursively by the divided-difference scheme while Thiele's interpolating continued fractions are grared towards determining a rational function which can also be calculated recursively by so-called inverse differences.

大家都知道，牛顿的插值多项式是基于均差的，可以递归出均差，而Thiele插值连分式是一个有理插值，也可以递归地计算，即所谓的逆。

The three great revolutionary upsurge as the key link of the basic idea was originally proposed by Hu Sheng. To as a sincere scholar, he advocated a clear-cut ideas and freedom of expression:""......'to me will prosper, against the I perish' is used on only an obscurantist ideology, because the temptation of Cyril and leather under the whip of punishment, not only to talk about freedom of thought, but also not to talk about ideas.""""

作为一位诚挚的学者，他曾旗帜鲜明地主张思想和言论自由：""……'顺我者昌，逆我者亡'用在思想上就只是一种愚民政策，因为在利禄的诱惑与皮鞭的惩罚之下，不但谈不到思想自由，也根本谈不到思想。""""

And these folds could be produced by the orogeny movement acting in the early Paleozoic.

然而这并不表明我们已经完全准确地认识了该构造带，恰恰相反，在一些问题上还存在着许多争论，如对早古生代该地区的构造变动及样式认识不清，对鄂尔多斯西缘逆冲褶皱带缺乏统一的认识等等，这些都直接影响到对该构造带的正确认识，因此对该构造带的研究还有待于进一步的深入。

Experiment results prove such method can effectively improve output current waveform of inverter.

实验证明了该方法能有效地改善逆变器的输出电流波形。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
