通过透镜

Another method, called microlensing--in which a planet's gravity momentarily brightens a background star by bending its passing light--is particularly good for detecting planets more distant from their stars and in principle could spot lightweights with masses down to that of Earth.

另一种方法即所谓的透镜--其中一颗行星的引力通过弯曲经过的光线瞬间增亮背后的恒星—-对于探测距离恒星更遥远的行星是特别好的，并且在原则上可以透过降落到地球上的物质发现轻量级的行星。

A tube containing a convex achromatic lens at one end and a ''.'slit'.'' at the other with the ''.'slit'.'' at the focus of the lens; light rays leave the ''.'slit'.'' as a ''.

Based on these and followed by proper reservoir classification and characteristics analysis,this paper established the methods for reservoir description of subtle pool with complex fault blocks,by which the main trap within the belt could be divided into fault block trap,structural trap and subtle trap which includes sand lens trap,lithologic updip thinning out trap,structural-lithologic trap and fault lithologic trap. For self-confined fault controlling oil flow,its height of oil column can be estimated by utilizing R.R.

在此基础上，通过油藏的具体分类和特征分析，建立了复杂断块隐蔽油藏的储集层和油藏描述方法；将东营凹陷中央隆起带中的主要油气藏划分为断块圈闭、构造圈闭和隐蔽圈闭，其中隐蔽圈闭包括砂岩透镜体圈闭、岩性上倾尖灭圈闭、构造-岩性圈闭、断层-岩性圈闭四类；提出在控油断层自密封的情况下，油藏高度可采用R.R。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
