使不变

Such life can make the person becomes tacit, those who change do not know how to talk, do not be willing to blather more, turn a dumb into the person, stationmaster of a dumb.

这样的生活会使人变得沉默寡言，变的不知道怎么说话，更不愿意说废话，变成一个不说话的人，一个不说话的站长。

It has been deduced that the search direction remains the same but that the step length decreases in optimizing the improved cost function with the conjugate gradient algorithm from the gradient of the cost function that the FIR filter apporaches the contrary point spread function more, and that the estimated image is closer to the original one.

从代价函数的梯度入手推导出共轭梯度算法，其搜索方向保持不变而搜索步长变小，使滤波系数更加逼近于点扩展函数逆算子，从而使估计图像与原始图像更加接近。

The be-all and end-all of life should not be to get rich, but to enrich the world.

生命的最终意义不该是使自己变得多么富有，而是怎样使世界变得更精彩。

By Llibre's algebraic invariant theory, at first on the basis of classification for quadric and quadric homogeneous binary polynomial, the plane linear and cubic homogeneous polynomial differential systems are classified.

利用Llibre的代数不变式理论，首先由二元二次和二元四次多项式的分类结果，对一次和三次齐次多项式微分系统进行代数分类，同时补充了已有结果中出现的漏洞；其次，由称共变张量空间的性质，对缺二次项的三次微分系统在保证轨线走向不变的前提下进行代数分类，使分类后同类系统的示性多项式有相同零点；最后通过讨论一类简单系统的有界性说明了分类的方便方处。

Based on two algebra Riccati equation method especially the structure of the system Hamilton matrix and system observability theory, the role of invariant zeros in constructing system reduced order controllers was given. That is, by the suitable selection of free parameters of the system H(subscript ∞) controller, some points which were symmetry with the unstable invariant zeros about the imaginary axis became the stable poles of the system controller which were not observable and could be reduced from the system, thus could get further reduced order controller.

基于2代数黎卡提方程方法，特别是系统Hamilton矩阵的结构特点和系统可观测性理论，论述了不变零点在构造系统降阶控制器中所起的作用，即通过选择控制器的自由参量，使某些不稳定的不变零点关于虚轴对称的点构成系统控制器不可观的稳定极点，从而实现了控制器进一步降阶。

This paper analyses the influence of scale factor on moment invariant features in discrete,constructs a new moment invariant with both scale,translation and rotating invariance.

分析了在离散状态下比例因子对不变矩特征的影响，构造了一种新的不变矩，使其具有平移、旋转和比例因子的不变性。

Here optimum'is reflected by theindex to be the smallestBut the controls through such sifting need not be real optimumones,because maybe there are other kind of variation or high order variation throughwhich the index have negative variation and the conditions are satisfied.

这里最优的意思是通过指标泛函最小来表示的但是这样筛选过的控制未必是最优的，因为还可能可以用其他方式的变分或高阶变分等来使约束条件不变而指标泛函的变分为正。

You find companies that without a doubt have been designed from the ground up to get you to work like a slave to make the owner of the company rich without ever giving you the potential to make anywhere near as much money as the owner of the company, and all the while the owners of the company go on and on about how much they care about their members, how much they value their members, and how they've created the company to give the member a truly wonderful opportunity.

当你考察这些多层次营销公司时，你就会发现毫无疑问的一点，公司设计的方案是让你像奴隶一样工作却使公司变得富有，而没有机会让你变得跟公司同样富有，这些公司的老板不会关系他们的会员，不重视他们的会员，更不会给会员一个真正的致富的机会。

The water content of the water content of the paper, directly influenced the business card printing and membership card to make the quality of the water content, right now, paper strength that is slowing down, the role of the epigene, the paper fiber will be pulled out, so that the plastic deformation increases brand drying rate affected; if the moisture content is too small, the paper will be issued with a crisp, easily damaged, generate static electricity.

纸张的含火量纸张的含火量的多多，间接感化着制卡和会员卡制息品的质量，含火量功多，纸张的不弱量会降矮，在边辛的功用下，纸张纤维会被不推出，使不不弹性变形加不弱，使痕迹的潮湿速量施到感化；如含火量功多，纸张会不收不韧，便当变不败毁坏，爆发静电等。

The presence and absence of γ-glutamyl transpeptidases in sprouting and dormant garlic bulbs were determined.The relation between the activity of γ-glutamyl transpeptidases in the garlic and greening of garlic purees was investigated.

通过测定休眠与打破休眠的大蒜中γ-谷氨酰转肽酶的活性存在与否，大蒜中γ-谷氨酰转肽酶活性的变化与蒜泥绿变的关系，以及在不能绿变的大蒜中添加γ-谷氨酰转肽酶而使蒜泥变绿，确定了γ-谷氨酰转肽酶对蒜泥绿变的作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
