There are generally four rules: selectivity law, interaction law, adaptation law and effect law.

修辞学的规律可以概括为四条：选择律、互动律、适应律、效果律。

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero.

我们刚刚讨论了描述质子，和电子之间相互作用力的定律，当距离变为无穷时，力变为零，那当距离变为，零时会发生什么？

Spanish mathematician Jose-Manuel Rey has calculated the "second thermodynamic law for sentimental interaction" and charted the trajectory of "sentimental equilibrium."

西班牙数学家何塞—曼纽尔•雷(Jose - Manuel Rey)已经计算出“情感互动热力学第二定律”(second thermodynamic law for sentimental interaction)，并绘制出“情感均衡”轨迹。

PROFESSOR: And this is a question based on where we left off on Wednesday -- we were talking about Coulomb's force law to describe the interaction between two particles and good job, most of you got this correct.

教授：这是我们上次最后,留下的问题-我们讲到,描述粒子间相互作用的,库伦定律，很好,大部分人都做对了。

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero. What happens instead when the distance goes to zero? What happens to the force?

我们刚刚讨论了描述质子,和电子之间相互作用力的定律,当距离变为无穷时,力变为零，那当距离变为,零时会发生什么？,这时候力是多少？

Due to the interaction of HIPAA (the Federal medical privacy law), CLIA (a Federal laboratory regulatory law), and state laws, patients can only get direct access to their their test results from labs in a handful of states.

For example, despite being called out for lagging behind, as of 2012 the FDA is now being required by law to produce and enforce guidelines on social interaction and drug company responsibility for third-party comments.
