- The specimen is mounted on a load cell which records the mass loss rate of the specimen during combustion. 这个标本是安装在称重传感器,记录燃烧过程中试样的质量损失率。
- It is found that the material surface becomes smooth following the mass loss in the decontaminating process. 结果表明:伴随着失重,试样表面变得光滑;电化学去污对材料抗腐蚀性能没有影响。
- 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。
