This thesis introduces the application of lithium reserve battery in fuze power source in foreign countries, analyzes the application speciality of lithium reserve battery in fuze power source and forecast the application prospect of this power source in future ammunition fuze.
By use of the actual operating data on June 5, 1999, the power flow and optimum reactive power flow of economic voltage difference in 500kV transmission line from Manwan to Caopu is calculated by the presented program and its results are compared with that from traditional OPF method. The comparison results show that with the presented method the voltage quality is improved, the line loss is reduced and the voltage stability reserve is increased.
Fengshun is one of the counties rich in geothermal resources in Guangdong Province. The geothermal resources are characterized of relative high temperature locally (60-92℃): large reserve. good in chemical contents.
In accordance with the constrained condition of coal reserve, water reserve and environment in Shaanxi Province, the technical countermeasures that Shaanxi power industry should take are discussed in the construction of resource-saving and environment-friendly power industry.
The protocol is founded on time division multiplex address and a different type of traffic is assigned to different priority, according to which a node should compete for and reserve the free slots in a different method.
The standing crop of N in the plant community was 1,025.28 kg/hm2, accumulation in the litter layer was 224.88 kg/hm2, and reserve in the soil was 55,151 kg/hm2.
Interspecific relationships in a natural forest dominated by Pinus kwangtungensis, a rare and endangered pine species endemic to China, were studied based on inventory data from 7,200 m2 plots in Nanling National Nature Reserve.
