The study on the inherent relations of microbial biomass in red soil with soil nutrient cycling and ryegrass growth shows that the microbial biomass was not only significantly correlated with soil organic C, total N and available N, but also highly correlated with dry matter yield and N uptake of plants,indicating that soil microbial biomass could be used as an important indicator for soil fertility and plant production.

The fourth part examines the semantic features of AN structure. It is concluded that AN structure is metric and its origin is that AN structure is transmitting structure with weak function. That is to say, because referential meaning of N is weak and declarative meaning is strong, N is made to be close to A to make the structure deviate in function. AN structure in sentences metricizes the attribute of verbs and it has the constraints of structural meaning on the internal structure of AN and VP.

第四部分考察AN结构的语义特征，得出：AN结构具有量度义，其来源是因为AN结构是弱功能传递型结构，即&N&的指称义弱，事物性虚弱、语义内容抽象，A的陈述义强，使得N向A靠拢，才使得由其构成的偏正结构在表述功能上发生了偏离，使整个短语性状化，具有了量度义；AN结构入句后表示对动作某方面属性的度量，这一格式义对AN结构内部、VP具有制约作用。

It is composed of above two mircoprisms dislocated and closely arranged, each microprism has three all-reflecting surfaces, N microprisms change the light beam into N vertical closely-arranged light beam groups, the distance between the light beam groups can be controlled by the difference of optical distance of the light beam between the first and second reflecting surfaces of the two adjacent microprisms and after shaped, the light beam does not change the advancing direction.

本整形器是由两片以上棱镜错位紧密排列构成，每片微棱镜有三个全反射面，N片棱镜使得光束变成N个垂直紧密排列的光束组，光束间的距离可由相邻两棱镜的第一反射面和第二反射面间光束光程差控制，并且整形后光束不改变前进方向。
