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

2%,effective gain≥10~4.

The results of the test indicate that more than 105 effective gain and about 24% energy resolution of 5.

The signal,effective gain and energy resolution of THGEM are measured with source of ~(55)Fe.

According to output benefit coefficient,consumption and return coefficient,population and substitution coefficient and intensive cultivation coefficient,quantitative analysis of cultivated land utilization benefit from 1996 to 2005 was carried out.

It analyzes on the cultivated land quantitatively on the basis of equation of cultivated land output benefit coefficient, cultivated land consumption and reciprocate, and cultivated land pollution and substitute coefficient, cultivated land utilization benefit.

Under the Plantation Occupancy-Compensation Balance Policy,the total yield capacity of plantation in Jiangsu province is descending due to the gradually consumed plantation resources during urbanization,so the major measure to guarantee provisionment is to increase plantation utilization efficiency.

5 cm) on the length of the lasing region is discussed.
