相对极

Comparison to the well-mixed greenhouse gases, aerosols are highly non-homogeneous in temporal and spatial distribution and have a short lifetime; it is difficult to observe directly. Therefore, more uncertainties about their effects are still existed in the research results.

不同于CO〓等均匀混合的温室气体，由于气溶胶的时空分布极不均匀，而且寿命又很短，观测资料和手段相对贫乏，因此，有关其研究的结果还存在很大的不确定性。

During the 20042005 austral summer season, the absolute gravity and relative gravity were measured at the Great Wall Station. The tide gauge was set up in Zhongshan Station in 2000. The SAR interferometry was applied to build the DEM of ice sheet and to monitor the ice flow in the polar region.

具体介绍了以长城站、中山站和黄河站3个GPS观测站为依托，开展的板块运动、卫星定轨及极区大气环境监测方面的研究；GPS在埃默里冰架、格罗夫山及Dome A考察中的应用研究；长城站的高精度绝对重力及相对重力测量；中山站自动验潮站的建立；及合成孔径雷达干涉测量在南极内陆冰盖的应用研究等。

One end of its metal shell is fusion connected to ceramic stem and another end is connected with the device to be tested.

金属外壳的一端与陶瓷芯柱相熔封，外壳的另一端与待测器件相接，离子收集极与电子发射体组件相对阳极环同轴非对称安装于金属外壳内。

Optical Proximity Effect, as a technical terminology, usually refers to all of the undesired pattern vs. layout distortions caused by mask making, optical lithography and etching.

当集成电路的特征尺寸接近曝光系统的理论分辨率极限时，在硅圆片表面制造出来的图形相对于电路版图会有明显的畸变，这种现象通常称为光刻邻近效应(Optical Proximity Effect，OPE)。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
