You could mark the fields transient, but the class would still have to explicitly produce code to check whether a field was initialized every time a method accessed it.
By use of numerical approximation method, the paper USES the polynomial to approach segmentally the transient electric field from dipole dipole array.
本文采用数值逼近的方法，逐段用多项式表示偶极—偶极排列的瞬变电场。
