拟核 meaning in English

nucleoid

This chapter proposes three conceptions , i . e . , kernelled quasidiferential , star - kernel and star - diferential , and establishes their operational properties . a sufficient theorem and a sufficent and necessity theorem for a quasi - kernel being a kernelled quasidiferential are proven . both the existence of star - kernel for a quasidiferentiable function and the existence of star - differential for a direnction - ally diferentiable function are established
在这一章里，首先给出核拟微分，星核与星微分的定义及其它们的运算性质；然后证明了拟核微分的一个充分条件定理及一个充要条件定理；最后讨论拟可微函数星核的存在性及方向可微函数星微分的存在性以及penot -微分与上下导数之间的关系。
