How to Determine the Optimal Structure of China's Expenditure on National Defense——An Empirical Study on the Distribution Proportion of Project Expenditure

Performance evaluation method of project expenditure is an important part of budget management.

Based on the idea of principal component analysis (PCA) discovering the principal component as quantitative association, the ratio item set is definited as.

To balance accumulation and allocation takes an important role in public hospitals continuous development.

Biomass of Chinese fir plantations in Fujian Province and its allocation among leaf, branch, stem and roots were studied based on the published biomass data.

It is proved that,in case that improper allocation is excluded,the efficiency of optimum allocation of random multivariate stratified sampling appears to be the highest,next to it is the efficiency of its proportional allocation,while that of the simple random multivariate sampling comes as the lowest.

Two methods for calculating distribution percentage of radiant heat gains from indoor heat sources;

Factors affecting the distribution percentage are analysed in the paper and some regular results are concluded with the distribution percentage calculated under different conditions.
