通过研究带限制的信号分配问题定义了半星色数,并最终解决了手机信号的最优分配问题,找到了半星色数与色数、星色数的密切关系。
The concept of half-star chromatic number is given by studying a singal assignment problem with constraint conditions , and the optimal assignment problem of singal is also solved in this paper . Furthermore , the relations among half-star chromatic number , chromatic number and star chromatic number are discussed .

在从样本星的色指数(B-V),(U-B)和视差得到它们的有效温度和光度之后,我们发现在赫罗图上它们大多数是位于主序带内的。
After deriving their effective temperatures and luminosities from their ( B-V ), ( U-B ) colors and parallaxes we find their positions in the HR diagram to be mostly confined to the main sequence .
