The on-line heat metering device uses MSP430F149 controller chip as collection of temperature signal and flux dynamic amending,transmits collecting heating information by data transfer,at last dispose and control based on ARM9 processor\'s embedded system.

Reconstruction has been made on an eccentric plier which is the only such machine of Russian made in the 1950s still remaining in China by computer control of which the model for speed tracker algorithm and dynamic correction is presented in the paper.

the aim-ing error in practical launching missiles, and thinking over the dynamic correction of thetarget s maneuvering movement in the course of guidance, the important conclusion aboutguiding the correct designing and using proportional guid.

The main causes of the dynamic error occurred in the weighing process are analysed,and an improved method based on dynamic correction and second-order prediction is proposed to reduce the influence on the data of preact.

The effects of such four ways,including local inflow unconsidered,local inflow considered,AR method considered,and both local inflow and AR method considered,were applied in the Cao e River.

Based on the effect of local inflow on the main channel stage, two methods were proposed to consider this effect in the BSRM in this paper.

Study on characteristics of horizontal well inflow performance considering variable mass flow in solution gas drive reservoirs

Condensate dropout is widely existent in development of condensate gas pool, usually different from gas inflow performance.

The key problem of producing nodal analysis for gas-water well is analysis of inflow performance of the gas -water well.
