System simulation shows that the proposed strategy can achieve higher system throughput and spectrum utilization than two existing uniform power allocation schemes.

The characteristic, spectrum, frequency utilize and error performance of these technology were introduced mostly.

A study on the physiological properties of root systems in various wheat varieties and the effects of their phosphorus uptake and utilization efficiency on the yields;

Apraisal about the utilization efficiency of sports resource in colleges and universities;

Analysis on Utilization Efficiency of Agricultural Water Resource in China s Central and Western Regions;

Effective ways to increase the utilization ratio of colleges and universities credit funds;

It is the requirement for the development of the civilian-run colleges and universities to enhance the utilization ratio of the educational resources.

Supply,uptake and use efficiency of N,P and K in aerobic rice and wheat rotation system;

In view of economic benefit and environmental protection,more and more attention has been paid to nitrogen(N)use efficiency by plants in recent years.

Six types of rice--conventional Japonica (Ⅰ), hybid Japonica (Ⅱ), conventional Indica (Ⅲ), hybrid Indica (Ⅳ), widely\|compatible cultivars (Ⅴ) and two\|line hybrid Indica (Ⅵ), were cultivated in continuously flowing nutrient solution to investigate differences of nitrogen uptake and nitrogen use efficiency between rice types.
