And this structure that I've depicted here using the X's and O's is called the Lewis structure. 我在这儿描述的结构,用X和O表示电子的方式叫做Lewis电子式。
Moreover, this paper analyses the chosen method of dynamic initial model, state vector's initial value x ( o) and variance Dx ( o). 此外,分析了动态初始模型选定方法、状态向量初值X(o)和方差Dx(o)的确定等有关问题。
