采样离散 meaning in English

sample variance

In the present digital era , with the advance of microcomputer technology , the discrete - time variable structure control research on the sampled systems become a hot - spot
伴随着数字时代的到来和计算机技术的发展，基于采样离散模型上的离散系统的变结构控制成为目前研究的热点。
In order to study usefully , both the image motion and the sampling discrete are simulated and the result shows that when the width of target strip is a constant ( 2a ) , the increasing amount of image motion is linear relation to the mtf decreased amount
为了使这种研究更具实际意义，接下来又仿真了像移和采样离散化共同作用下的成像，这实质是ccd探测器的动态成像过程。结论是：当目标条带的宽度一定时(仿真中取2a ) ，像移量的增加幅度与mtf的下降幅度为线性关系。
