BP和TP分别是什么的缩写? 它这里说的是 hcl的物理常数,全文如下: molecular weight 36.5 vapor pressure see attached curve normal boiling point -85.1 freeze point -114.2 latent heat of vaporization at bp 105.9 latent heat of fusion at tp 13.05 gas specific heat at 25c 0.202 cal/g-c liquid density at bp 1.191 g/cc critical temperature 51.4c critical pressure 81.5atm critical density 0.42 g/cc threshold limit value 5bppm 其他的我倒是都知道,就是那个bp和tp我不是很确定。查看更多
