运用个体时点固定效应的面板数据模型，构建比横截面数据模型更为真实的行为方程，并与传统的区位因素进行比较分析。

Also, the paper use an individual-time fixed panel data model to build a more real acts equation than the cross section data model, and compare with traditional factors.

只有模型，从宇宙哲学方程到人类行为原理的模型，才能连续的(尽管是不完美的)解释我们周围的世界。

Only models, from cosmological equations to theories of human behavior, seemed to be able to consistently, if imperfectly, explain the world around us.

仅从研究方程本身很难得到该函数行为的任何想法。

It is very difficult to obtain any idea about the behavior of this function simply from studying the equation.

After that, we'll move on to matter as a wave, and then the Schrodinger equation, which is actually a wave equation that describes the behavior of particles by taking into account the fact that matter also has these wave-like properties.

之后，我们会转移到物质，是一种波的话题和薛定谔方程，薛定谔方程是描述粒子,在考虑物质的波动性质后,的行为的方程。
