The Monte Carlo method was used to generate the random aggregate model, and the number of aggregate of different sizes was determined according to the actual mix proportion.

按照试件的实际配比计算出各种粒径骨料的数目，采用蒙特卡罗法对混凝土骨料进行随机投放，生成试件的随机骨料模型。

This paper develops a simple aggregate model of discrete-continuous demand to motivate how this correlation can be tested using simple regression techniques and readily available firm data.

在本文中，我们提供了一个简单的基于离散-连续需求的加总模型，用来说明对这种相关关系的检测如何可以用简单的回归实现。
