non-unit step integer 非单位步长整数
In this paper, a kind of non-parameter model is constructed with the unit step response of the nuclear reactor neutron dynamic system.
利用核电站反应堆中子动力学系统的单位阶跃响应数据，得到了该系统的非参数模型。
The non-parametric models of the unit-step response and frequency response and the dynamic performance index of both in time domain and in frequency domain are also given in this paper.
文中还给出了单位阶跃响应和频率响应两种非参数模型，以及时间域和频率域的动态性能指标。
In pre-matching, the searching strategy defines a gridding unit as a step with SSDA method, so it can quickly eliminate non-matching area and gain feasible area for precise-matching.
在预匹配过程中，由于地磁数据的离散性，搜索步长定为一个基本网格单元，并与序贯相似检测原则相结合，这样可快速排除非匹配区，筛选得到精匹配所需要的可行区域。
