所以callee知道传递了多少参数，它也就有能力自己来通过传递一个立即数给RET或RETF指令来移除栈中的参数，这样caller就不必做这个事情了。

Based on the criterion that the volume of estimated parameter's joint confidence region should be minimum, which is a sequential experimental design norm for optimal parameter estimation proposed by Box and Lucas, the observations for the adsorption of n -decane on 5 A molecular sieves were determined sequentially, and it is found that the observations should b.
