There are many reports about er applications presently , but the working mode of erf is flow mode or shear mode , the squeeze mode is few . a new type of er actuator - ripple ecectrorheological actuator ( rera ) is developed 目前，国内外有很多关于电流变应用机构的研究见诸报导，但电流变液的流动模式，大都是基于平动式或剪切式，也有少数基于挤压式的论文报导。
Circularly translational - moving polishing ( ctp ) is a new type polishing method with best kinematics conditions of polishing , and can obtain better work efficiency and quality than the traditional cmp method 圆平动研抛( circularlytranslational - movingpolishing , ctp )是一种新型的化学机械抛光方式。 ctp能实现抛光所需要的最佳运动学条件,所以能得到比传统的cmp更好的加工效果。

Due to the short distance among the planes which fly in a group , the conventional low resolution radar can not distinguish them in both distance and azimuth ? if we use the technology of isar to resolve the difference among doppler frequency of the targets and obtain a fine resolution cross - cross image , we may separate them , but a long time of coherent processing is needed < , for the formation targets , it can be approximately divided to rigid body and nonrigid body , so for the formation targets , that can be regarded as rigid which has a relative position and an identical movement , can be approximately considered as a large target , and be compensated by translational phase with the rule of minimum entropy , but for the most those cannot accord with the approximation of rigid , being the doppler - frequency of the aim is linear changed , by the relax method with short data , increases the resolving performance of multiple target to the aim in the frequency domain , since cross - range resolution is based on the accumulative time , so it is greatly improve the resolution to formation targets by the instant cross - range image which produced by radon - wigner transformation 低分辨isan成像及干涉技术应用研究一因此直接无法分辨编队目标的架数，我们借鉴isar的技术，通过较长时间的相干积累，在多普勒频域上对目标进行分辨。而对于编队目标，可分为近似刚性的多目标和非刚性的多目标，所以对于可以近似为刚体的编队目标相对位置固定，运动方式一致，可以近似看作一个大目标，采用最小墒准则对平动相位的进行补偿，但是大多数并不满足刚体近似的编队目标，由于目标在相干积累时间的多普勒频率近似呈线性变化，通过对较短数据利用relax的时频分析方法，提高了频率域上目标分辨的性能。由于横向分辨率取块于横向积累时间，所以利用radnwigner变换得到瞬时的一维横向距离像大大提高了对编队目标的分辨，对仿真和实测数据的大量分析结果表明此方法的有效性和可行。
In addition , research on esprit ( estimation of signal parameter via rotational invariance technique ) super - resolution imaging technology is made to improve image quality , especially in the case of small segment of viewing angle . afterward , a new multi - target isar imaging method for high - speed targets is presented 2 .在方位向的补偿(相位校正)方面,利用多重的离散傅立叶变换( dcft ) ,对目标平动引起的相位线性调频项的调频斜率进行精确估计,并直接构造补偿项对各个距离门进行补偿。
