黑色物质

A few craters, such as some in the huge Caloris Basin impact feature visible on the upper right, appear unexpectedly to be ringed with a dark material, the nature of which is being researched.

比如，影像右上角可以看到一些陨石坑在巨大卡罗维斯低地的碰撞特征，看上去有黑色物质环绕，形成的原因正在研究中。

The black bone sheep and the sheep in Lanping and Luomuni sheep were chosen as materials for the measurement of TYR activity of blood and melanin content of tissues and organs.

测定了乌骨绵羊、兰坪本地羊和罗姆尼羊血液TYR活性并分析了乌骨绵羊与乌骨鸡组织器官黑色素结构，结果表明：乌骨绵羊TYR活性显著高于兰坪本地绵羊和罗姆尼羊(P.05)；乌骨绵羊黑色素与乌骨鸡黑色素的IR光谱基本一致，黑色物质主要是真黑色素。

There are two types of black materials: one kind of them absorbs visible light through electron transition to form black, such as nigrosine, anthraquinone black, and iron oxide black, the other kind such as carbon black reflects and absorbs visible light several times with its superficial porous effect to form black.

现有黑色材料主要有两大类：一类是通过化学物质的外层电子吸收可见光跃迁来形成黑色，如苯胺黑、蒽醌黑、铁黑等；另一类则是利用材料表面的多孔结构，对光进行多次反射和吸收，形成黑色，如炭黑。

By observing and measuring this light, researchers can figure out the location and even size of the object, whether a star, galaxy, or cloud of gas, responsible for the bending.

谨慎的研究这样的碰撞，科学家现在说他们已经找到第一个黑色物质存在於宇宙中的证据。

According to their simulation, gravity acted on minute density variations in matter, gases, and the mysterious "dark matter" of the universe after the Big Bang in order to form this early stage, of a star-a protostar with a mass of just one percent of our sun.

根据他们的模仿，重力作用在物质、气体和大爆炸之后的神秘的宇宙&黑色物质&的微小浓缩变体，是为了形成星系的最初阶段--一颗原初星仅仅占我们太阳的百分之一。

The other was announcement earlier in the week that scientists found direct evidence for dark matter.

另一个是这周早期宣布的科学家发现的关于黑色物质的直接证据。
