您要查找的是不是：
- The Schwarzschild radius of a solar mass black hole is about 3 km. 太阳质量的黑洞的史瓦西半径约为3公里。
- If a star is less massive than about 0.4 Solar mass, its life will be quite uneventful. 一颗小于太阳质量0.;4倍的恒星;它的一生是非常平静的。
- What, then, accounts for brown dwarfs, which tip the scales at merely a few tens of Jupiters (a few hundredths of a solar mass)? 那麽，如何才能解释棕矮星仅有数十颗木星的质量（太阳质量的百分之几）呢？
- Cygnus X-1 must have a mass of about 7 solar masses or else it would not exert enough gravitational pull to cause the wobble in the spectral lines of HDE 226868. 天鹅座X则必须有7个太阳大小的质量，否则它将不会有足够的引力来引起HDE226868谱线的来回波动。
- Observationally, the lightest black hole candidates are about six solar masses. 观测上可能是黑洞的天体，最轻的大约是六倍的太阳质量那麽重。
- Solar masses within a few light weeks. Only a black hole allows the presence of so much mass in such a small region. 个太阳质量,但直径只有数光星期之内的物体,只有黑洞才可能这么重而同时又这么细小。
- Because a collapsing core containing a solar mass of gas is divvied up among 10 or so embryos, the expected result is a handful of stars each with at least a tenth the mass of the sun. 含有一个太阳质量气体的塌缩云核可分割成10个左右的胚胎，可预期的结果是会产生数颗恒星，每颗至少有太阳质量的1/10。
- In addition, nearly every galaxy contains a supermassive black hole at its center, with a mass ranging from millions to billions of solar masses. 另外，几乎每个星系的中心都含有一个超大质量的黑洞，其质量从数百万个到数十亿个太阳质量。
- The first is stellar-mass black holes, having a mass of a few solar masses as the name indicates. They are the end products of stellar evolution for very massive stars. 第一类称为恒星质量黑洞,这类黑洞的质量与太阳质量的量级相若,它们都是巨大恒星演化后的最终物。
- For example, the sizes of black holes can vary immensely from a few to a few billions of solar masses! 不同类型的黑洞,其大小竟然可以由几个太阳质量至几十亿个太阳质量不等!
- Markarian 273 has an intense region of starburst, where 60 solar masses of new stars are born each year. 马卡林273有一片强烈的星暴区，每年有60太阳质量的新恒星诞生。
- A cloud is a mass of vapor in the sky. 云是天空中的水汽团。
- The second category is the supermassive black holes found at the center of galaxies, each millions to billions of solar masses in size. 第二类黑洞称为超级黑洞,它们位于星系中心,这类黑洞的质量由数百万至数十亿太阳质量不等。
- Whereas reionization kept galaxies smaller than a few hundred million solar masses from forming, outflows may have squelched galaxies 10 times larger. 因再游离过程使质量小于几亿个太阳质量的星系无法形成，而喷出物则可能粉碎大上10倍的星系。
- In addition, uncertainties in the distance to the binary system would also influence mass calculations. All of these uncertainties can make a case for Cyg X-1 having only 3 solar masses, which would point to it being a neutron star. 此外，双子系统的距离不确定性同样也会影响质量的计算，所有这些不确定性可能会使大鹅座X－l的质量只有3个太阳那么大，这样它就是一颗中子星。
- But galactic black holes, such as those in NGC6240, are much larger, equal perhaps to millions of solar masses, and are usually at the center of galaxies. 但星系黑洞如NGC6240中的黑洞要大得多，质量相当于几百万个太阳，通常位于星系的中心。
- Medium-size black holes are much less massive than the supermassive black holes, which are up to billions of solar masses and reside in the centers of large galaxies. 中等大小的黑洞比超大黑洞的质量要小很多，超大黑洞的质量可以达到数十亿个太阳系质量，兵存在于更大的星系中。
- The mass rally was a total fiasco. 那次群众集会彻底失败。
- The supergiant star is at least 20 times larger than the Sun, contains 30 solar masses, with luminosity one million times greater and a temperature of 20 000 K. 该巨星至少比太阳大20倍，有30个太阳质量，光度是太阳1百万倍温度2万度。
- Let's collect the sap before its consolidation into a hard mass. 让我们在树液坚固成团之前将之收集起来。
