The conclusions are as follows:(1) Neologisms in each Huayu region can be classified into two major categories:self-originated and others-originated,among which the new-born words are "absolute new words" and the inherited word are "relative new words",and there are also others-originated elements in the morphemic and sense systems of new words;(2) Variation can be seen in the morpheme,formation,building and sense of new words in Huayu regions,besides individuals of new words;(3) Aggregation of current new words and compound words with one common morpheme and a same construction,together with the aggregation of synonyms and that of different senses in polysemies,reflect the relevance of the systems of new words in Huayu regions in their variation;(4) Regular participation of hinting sense of a formation element in forming and building new words is an important way of producing new sense of morpheme,and an important reason for the current emergence of words with more than one new senses;(5) Compared with ordinary words,the productivity of ways of word formation in forming new words both in general and of a particular class will change and new ways of word formation appear in Huayu regions;(6) The semantic collocation of the verbal morpheme of new verbs in a phrase has a great influence on the location of its structural center,and the complex syntactic behaviors of new verbs are related to the different processes of argument integration;(7) The processes of building new words with the same meaning differ in levels of approaches to motivation cognition,perspectives of motivation cognition,morpheme motivation and morpheme expression,etc.;(8) The lexical interaction in Huayu regions results in lexical subsystem intersections of current new words across two,three and four regions.

Angular spectral is spectral value map formed by estimating semblable coefficients of fast and slow shear wave or the variation of amplitude ratio of fast and slow shear wave with times and angles at a specified space point based on semblable theory of fast and slow shear wave, the angle value of this space point at a given time can be got by picking the maximum of angular spectral; the study reveals that fast and slow shear wave with different polarization direction should be separated using different rotation formula, eight formulas of separating fast and slow shear wave using clockwise rotation and counterclockwise rotation have been derived, and gained energy assignment rule and phase coincidence rule, in real data estimation, the rotation formula used for separating fast and slow shear wave can be uniquely determined on the two discriminating rules. On the basis of semblable theory of fast and slow shear wave, the delay time corresponding to the maximum of semblable coefficients at a specified point in a given time window is the delay time of fast and slow shear wave, delay time section of fast and slow shear wave can be got by moving space point and smoothing time window.
