3) stochastic model
随机模式
1.
In this paper, using perturbation teChnique of one order approximation, a quartic nonlinear stochastic model of air-sea interaction is deduced to a linear system with random item and a nonlinear system without random item.
本文首先对一个假定随机强迫为高斯白噪声的四次方非线性海气耦合随机模式进行了ε一阶近似的摄动处理，将非线性随机模式化为显含随机项的线性系统和隐含随机项的非线性系统，通过对输出响应的分析表明：该模式结构和随机项的特性使得随机强迫输出的响应只能通过模式的线性区；非线性项仅对气候系统的方差及其对应的频谱有一定量的偏差作用。
4) logging while drilling(LWD)
随钻测井
1.
The comparison between logging while drilling(LWD) and wireline logging(WL) curves of a oilfield shows that: the depth,value of resistivity,and distribution range of density of the LWD measurements are rather close to that of WL,invasion effect in LWD is less than that in WL,so LWD can provide more credible information for oil-gas interpretation and formation evaluation.
