前后移动

After analyzing and processing the grating reticle image collected by CCD, the mapping coefficient can be accurately calculated from grid size to pixels. Comparing the fore-and-aft two grating reticle images after the worktable moved. Adopting phase difference ratio arithmetic based on Lissajous figures,the phase difference of two images will be figured out. The displacement of the worktable can be further calculated by the mapping coefficient.

A method for identifying the damage, using the influence line curvature of deflection differential values at a point before and after the damage is proposed, that is, when the moving load is in the area without the damage, the influence line curvature is zero, however when the moving load is in the area with the damage, the influence line curvature evidently increases and has the relationship with the positions of the damage points and the rigidity of the beam before and after the damage.

提出利用损伤前、后某一点的挠度差值影响线曲率来识别损伤的方法，即当移动荷载位于无损区域时，挠度差值影响线曲率为0，当移动荷载位于有损区域时，挠度差值影响线曲率明显增大，且与损伤点的位置、损伤前后的刚度有关。

Taking two sequential time satellite images and dividing them into 32 × 32 pels subset, and obtaining the optimization matching region by using of cross-correlation analysis, the cloud cluster motion vectors were estimated according to the location and time interval of the images fitting region.

选取连续两个时次的卫星云图，采用交叉相关法计算获取两幅云图的最佳匹配区域，根据前后云图匹配区域的位置和时间间隔，确定每个图像子集的移动矢量，并进行相应的客观分析；随后，基于检验后的云图移动矢量集，利用后向轨迹方法对云图作短时外推预测。

The pattern of lunar cycle can be classified into three strategies:(1) Planulation of S. hystrix and P. damicornis showed clear lunar periodicity and the peak of larval release shifted with different months. The peak of planulation occurred around the full moon in winter then shifted gradually to the first quarter moon phase in summer. The phase shift of larval release may be related to the seasonal variation of seawater temperature and the sudden temperature drops caused by upwelling.(2) Planulation of S. pistillata showed clear lunar periodicity and the peak of larval release occurred around the full moon.

在月周期方面可分成三种生殖策略：(1)尖枝列孔珊瑚与细枝鹿角珊瑚释放幼生不但有明显的月周期，而且释放幼生的高峰会随著月份而移动，由冬季至夏季期间，高峰从满月前后转变至上弦月前后；再由夏季至冬季期间，高峰从上弦月前后转变至满月前后，而此变动形成一个完整的年周期，原因可能与海水温度影响配子发育和胚胎速度与夏季期间涌升流所造成的降温有关。

Constitution:the button-sewing machine comprises:a fixing means 构件 for fixing a buttonand an article being sewn;a moving means for moving the fixing means to stitch the button to the article being sewn with seams of a specified sewing pattern; a fixed blade; a moving blade for drawing a thread and then moving to cut the thread by the cooperation with the fixed blade;and a button,wherein the machine has a control means for controlling a fabric transferring means to move the button to a preset position before cutting the thread.

一种钉扣机，设置有布料保持件的可动、固定切换机构，该切换机构在钉扣缝制时可在以下两种状态之间进行切换：将布料保持件固定保持在规定位置上从而停止该布料保持件在左右方向上的移动的状态、或者解除对布料保持件的位置固定从而使该布料保持件通过可动台与纽扣保持件一起在前后方向、左右方向上移动的状态，在该切换机构上安装有可在左右方向上的一定范围内调整布料保持件的固定保持位置的位置调整机构，由此可使整体结构简单，可实现小型化、轻量化及低成本化，且即使在将柔软的布料作为缝制对象时也不会出现缝制褶皱等，另外，无论线的种类和粗细如何，都可进行缝制品质高的钉扣。

In the computer chassis before and after the panels are left in USB interface, we should, if possible, mobile hard drive inserted into the chassis back panel USB port, after all, the back panel of the USB ports are integrated directly into the computer motherboard, this USB port are generally considered safe grounding design, we found the body of the static it becomes hard to move a threat to the safety of the hard disk USB interface.

在电脑机箱前后面板中都留有USB接口的情况下，我们应该尽量将移动硬盘插入到机箱背面板上的USB端口中，毕竟背面板上的的USB端口通常直接集成在计算机主板中，这种USB端口一般都有安全接地的设计考虑，所以我们人体身上的静电就不大容易威胁到移动硬盘USB接口的安全。
