开普勒第二定律，也即面积定律，指出从太阳到行星所联接的直线在相等时间内扫过同等的面积。
The second law, the law of areas, states that a line connecting a planet to the sun covers an equal area over equal periods of time.
所以定律说，扫过的面积是常量，意思是这两个是成比例的。
So, to say that the rate at which area is swept is constant means that these two are proportional.
雪崩的大小、面积和时间分布均满足幂次定律，但是不同相称度下的动力学指数不相等。
The probability distributions of the size, the area and the time of avalanches all follow the power law, but the dynamic exponent varies with the degree of assortativity.
单位时间扫过的面积为常量，这就是开普勒三定律之一。
The rate of sweeping out of area is a constant-this is one of three Kepler laws.
利用几何方法及计算机模拟研究开普勒第二定律，运算结果面积速度近似为常量，本文中精度为1 0 - 13。
Using a geometric method and computer simulation, the second Kepler's Law is studied. The calculated result shows that the areal velocity is approximately constant with an accuracy of 10 -13 .
