Magnetotelluric field finite difference migration tomography Found on the researches of Zhdanov etc. in MT finite difference migration tomography, we analyze and summarize both fruits and limitation of foregone peoples' achievements. So more precise finite difference extrapolation equation can be deduced, and it can be easily applied into the migration tomography. New equation reserved the derivative terms of wave number both at vertical and horizontal direction, so that more exquisite geoelectric diversification can still be accommodated, that is the very requirement of practical data interpolation.

大地电磁有限差分偏移成像技术：在Zhdanov等人建立的有限差分偏移成像研究的基础上，总结分析了前人在 MT成像技术方面的研究成果和存在问题；推导更精确的有限差分波场延拓方程，采用改进的有限差分法进行大地电磁场偏移成像，差分延拓方程保留波数对水平方向和垂直方向的一阶导数项而提高求解精度，可适应电性纵横方向变化剧烈的地电构造，使成像分辨率得到增强。

In the simplest type of splitting, somewhat misleadingly called the "normal" Zeeman effect, because it was the first to be explained within the classical theory, a single line splits into three lines when observed in a direction perpendicular to the magnetic field.

最简单的分裂类型，从垂直于磁场的方向观察，一个光谱线分裂成三个光谱线，这种类型多少有点误导地被成为&一般&塞曼效应，因为它在经典理论中第一次解释了这种现象。

After transverse Zeeman effect is introduced to reduce the mode coupling, the laser could produce two orthogonal linear polarized components with 5MHz beat frequency. The effect of the magnetic field's direction to generation of the dualfrequency and the polarization property of the laser is investigated Based on theoretical study and experimental investigation to the beat frequency tuning character, a novel method for stabilizing the laser beat frequency is brought forward.

现代机械工业的发展使得机床、三坐标测量机等的运行速度已提高至1m/s，为适应这种发展趋势，本文研究了高频差（5MHz）激光干涉仪的光源、稳频和外差信号的处理等基本问题，建立了测量速度可达1m/s的高测速激光干涉仪，并对其在加工中心主轴热漂移测量系统和加工中心误差实时测量系统中的应用进行了研究。

Come on, he said, storming off across the field in the direction of Roca Negra.

来吧。他朝着罗卡尼格拉的方向咆哮到。

The tectonic stress field is strike-slip motion, and the direction of maximal stress is controlled by the subduction of the Indian plate, Pacific plate and Philippine Sea plate.

4现代构造应力场以水平向构造应力场作用下的走滑运动为主，最大主应力方向受印度板块和太平洋板块、菲律宾海板块的俯冲挤压方向影响。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
