Cormel formation was induced by PP.vo, the critical concentration of its function was between 0.5 mg/L and l.0mg/L, 5.0mg/L was the best treatment for cormel formation .

PP_(333)可以诱导子球的形成，诱导子球形成的阈值浓度在0.5～1.0mg／L之间，最适浓度为5.0mg／L。

Following developments in electrical theories such as Coulomb's law , which showed that positive and negative charges attract, analogs in human life were developed, such as "opposites attract."

随着电学理论的发展，例如库仑定律的提出表明异种电荷相互吸引，类似的概念在人类生活中也被提出，例如"异性相吸"。
