8-2同余式 8.2.1有理整数环中的同余的定义 定义8.5设m是一个正整数,若a,b∈Z,且ba∈(m),亦即m(b-a),则 称b与a模m同余,记作b=a(modm)。不难得到,b与a模m同余就是它们用m做带 余除法所得的余数相同。整数模m同余为一等价关系,验证如下:

In this lecture, we consider the problem of a body in which the mass of the body changes during the motion, that is, m is a function of t, i.e. m(t). Although there are many cases for which this particular model is applicable, one of obvious importance to us are rockets. We shall see that a significant fraction of the mass of a rocket is the fuel, which is expelled during flight at a high velocity and thus, provides the propulsive force for the rocket
