两星体

When two Northern farmers claimed that they saw a meteoroid fall from their sky to their farm, Thomas Jefferson remarked

这种理论被两个北部农民的经历很好的反驳了，他们看到流星体从空中坠入他们的农场，然而 Thomas Jefferson 仍评论到

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1 stellar radiation may be represented by some black body equivalent and 2 within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

本文对着当前的发展，综述了照相方法在恒星光度学中的地位。接着用两个简单的假设，即星体幅射的黑体近似和累积亮度范围中的直线近似，把恒星光度学中的基本定义(如有效波长、等光波长和色指数等)和主要问题(如空间红化，亮度效应等)表以公式。

In the case of both the Moon and Mars, it is generally concluded from the appearance of their heavily cratered surfaces that they have been subjected to bombardment by large meteoroids during their geological history.

月球和火星两方面，它通常总结出在它们的地理历史中受大流星体所攻击的深而多坑的表面。

In prophase, it localized on the microtubule organizing-center. In metaphase, it co-localized with α-tublin completely on spindle. In anaphase, it co-localized with α-tublin in aster and mid-zone. In telophase, it co-localized with α-tublin in cytoplasmic bridge connecting the two daughter cells.

在分裂前期，hSMP-1蛋白位于微管组织中心区域；在分裂中期，hSMP-1蛋白与组成纺锤体的微管呈完全共定位；在分裂后期，hSMP-1蛋白与星体和纺锤体中区的微管呈共定位关系；在分裂末期，hSMP-1蛋白则与两个子细胞之间的胞质桥完全共定位。

The accretion of these "planetesimals" is believed to take a few hundred thousand to about twenty million years, with the outermost taking the longest to form.

这些微行星体的增长会用到几百万年到2千万年的时间，而最外面的部分最晚形成。八、&两个关键&和第二减速点。

When in an Election you cannot fit the Moon to two Planets that you have occasion for, at once, join her to some fixed Star that is of the nature of them both.

择时择日时，当你无法让月亮与你希望的两个星体同时有相位时

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
