查询词典 undulatory theory

Typical methods of the first class consist of predictive deconvolution, normal moveout interconversion stacking, f-k transformation, tau-p transformation, parabola Radon transformation and beamforming. They can be called as seismography method based on the geometry. The second class methods, mainly bases on elasticity undulatory theory, through simulation or reversal development method forecast multiple, and then match it with the original data.

比较典型的方法有预测反褶积、正常时差变换叠加、f-k变换、τ-p变换、抛物线 Radon 变换和聚束滤波等，它们可以简称为基于几何地震学方法或"几何滤波类方法"；第二类主要是基于弹性波动理论的方法，通过模拟或反演方法来预测原始数据中多次波，继而从原始数据中匹配减去所预测的多次波。

Using index in the financial early-warning in the microcopic economy subject, the origin is in the cycle undulatory theory and booming theory in the macroscopic economy early-warning.

将指数用于微观经济主体的财务预警中，其理论来源是周期波动理论和宏观经济预警中的景气理论。

In the foundation of cycle undulatory theory, the booming theory founded the booming index, using it to monitor the influence of macroscopic economy by cyclical undulation.

The cycle undulatory theory tell us that there is certain periodicity in economical development. This kind of periodic performance almost simultaneously expands for the many economic activity, then universal declines, contracts and recovers, thus influend economy development.

周期波动理论认为经济发展存在周期性，这种周期性表现为很多经济活动差不多同时扩张、继之以普遍的衰退、收缩与复苏，从而影响经济的发展；而景气理论则是在周期波动理论的基础上，构建景气指数来监测宏观经济受经济周期波动的影响。
