No single star formation mode with a constant star formation rate (ser) and an invariable initial mass function (IMF) can fit the observations of globular clusters.
没有一个单一的恒星形成恒定的恒星形成率(SER)和一个不变的初始质量函数(IMF)的模式适合球状星团的意见。
Since the MASS vector functions are much faster (by a factor of up to about 30) than a repeated call to a standard library function, the resulting performance improvement can be substantial.
因为MASS向量函数要比对一个标准库函数的重复访问快很多(倍数接近30倍),所以最后得到的性能改善效果将会是惊人的。
