The external scale of cobalt sulfide and yttrium oxide-surfide particles in the inner scale were found respectively after corrasion in Pa .!$+ lo-'' Pa Q. Beneath the external scale, a region of internal sulfidation-oxidation of yttrium was also present. The comion pduct in lo-' Pa .!$+ 10-l5 Pa Q was only a very thin surface layer of yttrium oxysulfide and an internal oxidation zone of yttrium.

并有助于降低纯Co的腐蚀速率，10＾02Pa硫压下，合金表面形成的腐蚀产物为多层、以为硫化钴，中间层为由两金属化合物怕成分复杂的混合物层，最内层是由氧和硫引起的Y的内腐蚀区；在10＾－3Pa硫压下，合金没有形成外层硫钴，仅在表面形成较薄的Y的硫氧化物，其下为Y的内氧化区。

说明：猫眼星云是（NGC6543）天空中最著名的行星状星云之一。这张令人印象深刻的广角影像的较亮中心区域中，我们能看到更为熟悉的星云外层轮廓。

The Earth possibly is one by occupies the major part material stably the counter-flow inner layer as well as occupies the few parts the counter-flow outer layer to be composed, the former is constitutes the Earth quite stable movement, the attraction, the magnetic field and so on the macroscopic phenomenon foundation; The latter constitutes the Earth most to be rich in the change the beautiful semblance, such as: Land, islands, volcano, earthquake, plate movement and so on nature environment with each kind of great phenomenon, eliminate this this also are decide the Earth for the perfectly round spheroid basic reason, because the internal heat circular reactions is from starts, the huge energy finally becomes the Earth good fortune a beautiful rich life the star.

地球可能是一个由较稳定占绝大部分物质的对流内层以及占较少部分的对流外层组成，前者是构成地球比较稳定的运动、引力、磁场等宏观现象的基础；后者则构成地球最富于变化的美丽外表，诸如：陆地、岛屿、火山、地震、板块运动等等自然界环境与各种伟大的现象，除此这也是决定地球为浑圆球体的根本原因，因为内热循环反应是从一点开始的，巨大的能量最终把地球造化成一颗美丽的富有生命的星球。

At the dimmest part of a Cepheid's cycle, the ionized gas in the outer layers of the star is opaque, and so is heated by the star's radiation, and due to the increased temperature, begins to expand.

在造父变星的一个光变周期开始时，恒星最暗，此时其外层电离气体是相对不透明的，因此会吸收恒星的辐射而升温，并开始向外膨胀。

After 45 days of having tissued, the record showed that the three parts flake of L.davidiivar Cotton did not have the same differentiation ability in the same matrices.The alive rate in each matrices is: the middle is the best, the outer is the worst and the innner is better.

培养45天时统计了各种基质中的成苗情况，结果表明，在16种基质中，每一种基质都证明了兰州百合内、中、外三层鳞片在同一基质中的分化能力不同，每一种基质中中层鳞片成苗率最高，内层次之，外层最差。
