变小

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。

On a convex surface, the pressure is less than

在凸面上，底面压力变小，向心力与水的自重方向一致；在凹面上，底面压力变大，向心力与水的自重方向相反。

I've been using this creme for over a month and my skin is firmer and the pores are smaller.

我使用这款产品1月有余了，我的皮肤变的更加紧致且毛孔变小了。

Cupper atom is formed by means of the decomposition of CuBr into Cu;++, and then recombination of Cu;++. Consequently the recombination coefficient is bigger and the delay time of laser pulse gets longer when the working temperature is lower.

由于工作物质铜原子是通过分解CuBr成为铜离子，再由铜离子复合成铜原子，故工作温度较低时，复合系数较大，造成激光脉冲的延时时间变长，而当工作温度较高时，复合系数变小，使激光脉冲提前。

SW620/pRETRO-On-TRAIL cells become round and small,dioptre of ellsbroken cells increase.

用相差显微镜观察细胞形态发现，SW620/pRETRO-On-TRAIL细胞经四环素诱导后，变圆变小，贴壁性差，折光性强，细胞碎片增多。

The distribution ratio of copper between slag and metal went up with the raise of temperature.

铜在渣金间的分配比随着温度的升高而升高，但温度对低浓度下的分配比影响更大一些，在高浓度时其影响变小，分配比的增势明显变缓。

The wind died down at last,and all was quiet.

风终于变小了，一切都变得静悄悄的。

We want to live in the big city again. We could downsize and simplify.

我们现在又想生活在大城市了，在那里我们的生活圈子可以变小并且生活可以变得更简单。

To meet the needs of detection of space faint objects for a telescope with large aperture and short focal,a binding drawtube telescope scheme to detect space object is presented to overcome the shortcomings that focal length grows and field of view shrinks with the increasing of aperture size in traditional telescope for space detection.The software methods are used to stack collected images to restrain background random noises and to improve image Signal to Noise Ratio and the detecting ability of the whole system.

为了满足空间暗弱目标探测对大口径、短焦距望远镜系统的要求，克服普通望远镜随着口径的增加焦距变长、视场变小的不足，提出了将多镜筒捆绑在一起对同一空域进行观测，通过软件的方式对采集的图像进行叠加来抑制背景随机噪声、提高图像的信噪比和系统的整体探测能力的设想。

But there is evidence that the advance to cooking and using knives and forks is leading to crooked teeth and facial dwarfing in humans.

但有证据显示，烹调以及使用刀叉等餐具的进步使人类的牙齿逐渐变得弯曲不整齐并使人的面部变小。

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
