双动

According to perturbation theory and local Born approximation method, we derived the full DSR migration approaches based on the dual-domain propagators.

在前人研究的基础上，本文首先参照摄动理论和局部Born近似方法，系统地推导了基于双域传播算子的DSR全偏移方法。

Potentiodynamic polarization and electrochemical impedance spectroscopy techniques were applied to investigate the corrosion behavior of LY12CZ in 3% NaCl aqueous solution. The effects of stress to anodic polarization behavior, free corrosion potential, breakdown potential, polarization resistance and double-layer capacitance of LY12CZ were summarized.

利用动电位极化和电化学阻抗谱技术对应力加载下的LY12CZ铝合金在3% NaCl水溶液中的腐蚀行为进行了研究，考察了应力作用对LY12CZ在3% NaCl水溶液中的阳极极化行为、自腐蚀电位和破裂电位以及极化电阻和双电层电容大小的影响。

Fog creeping into the cabooses of collier-brigs; fog lying out on the yards, and hovering in the rigging of great ships; fog drooping on the gunwales of barges and small boats. Fog in the eyes and throats of ancient Greenwich pensioners, wheezing by the firesides of their wards; fog in the stem and bowl of the afternoon pipe of the wrathful skipper, down in his close cabin; fog cruelly pinching the toes and fingers of this shivering little prentice boy on deck.

雾悄悄漂进双桅运煤船的厨房；雾笼罩着船厂，盘旋在巨轮的索具上；雾垂降在驳船和小船的船舷上缘；雾漂进古格林威治跟班的眼睛和喉咙，在他们护卫们的炉边窜动着；雾挂在愤怒船长午后烟斗的烟干和烟锅上，漂进他的舱室；雾在甲板上冻得浑身发抖的小男学徒脚趾和手趾缝间肆虐地啃咬着。

CJX2-d The operating mechanism is direct operation type ,the comtact has double comtas;Combinatiom function,exce pt the imstallation side,the rest of the sides can be added with auxiliary comtact group(F4-d) or interlocking mech anism; The head can be equipped with auxiliary contact group (F4-d)or (F4-d2) or air delaying comtact (sk2-2/3d);The coil wiring terminal can be connected with time delayer and so on function modules.

Because it will show double refraction after the sine wave operate on crystal, it will make the latter part of this system, the signal disposal part, give demand with detecting the output wave and deal with it so that the system can meet the demand of the system. The system can be applied to the occasion of automatic control system etc.

利用正弦波通过晶体后能产生双折射现象，使系统的后一部分——信号处理部分通过对其的检测、处理，给出命令信号，进行随动跟踪，然后应用于自控系统等场合。

Chrome is relatively simple to integrate a number of very useful features, such as mouse gestures, IE TAB, download software support, drag open a link, double-click the close tags.

相对简单的Chrome来说，整合了多个非常实用的功能，如鼠标手势，IE TAB，下载软件支持，拖动打开链接，双击关闭标签等。
