查询词典 back surface

The dynamic surface controller design method of the nonlinear autopilot for high maneuver missile is developed. Based on the smooth second-order dynamic sliding mode, the designed virtual controls are smooth enough and needn't smooth by integral filters when designing the inner loop controller with back-stepping method. So it overcomes the problem of explosion of terms.

提出了高机动非线性导弹自动驾驶仪的动态面控制器设计方法，该方法基于光滑二阶动态滑模，所设计的虚拟控制足够光滑，在利用反步法设计内环控制器时不需要进行积分滤波克服了反步法所带来的项数膨胀问题。

It should drift back from the boat, floating on the surface, and should terminate in a large, visible float.

它必须能够从船上拽回，能够浮在水面上，尾端固定在一个足够大的可见漂浮物上。

At the same time, the relationship between the magnetic flux leakage signals and the physical characters (including the width、depth and position) of the corrosions are studied. The results identify that, if the floor is saturated, the magnetic flux leakage intensity changes linearly with the changing of the corrosion diameter. When the corrosion is in the surface, the peak value of the signal is higher than it's in the back.

同时对缺陷直径、深度以及处于底板上不同位置所产生的漏磁场信号差异进行研究，结果表明，在磁化饱和条件下，平底孔缺陷漏磁场信号峰峰值与孔深度呈线性关系，相同大小的缺陷处于底板下表面时检测信号强度大于处于底板上表面时。

Studies have shown that the deepest and flattest bass response is typically attained when a subwoofer is placed within a few feet of one of your room's corners ( leave about 3 in the back for cable clearance with any wall or other surface ).

研究表明，深和平坦的低音反应通常实现于当一个低音炮放在房角几英尺范围内时（后部离开约墙面或其他表面3 ，以便留出电缆的位置
