Trough experiments,the impacts of refrigerant charge amounts and capillary tube lengths on the refrigeration system was investigated,and a series of corresponding curves was drawn to find the optimal matching relations,and then according to the results of experiments,the influences of the refrigerant charge amounts and capillary tube lengths upon the performance of air conditioner was analyzed.

In order to achieve high-efficiency white LEDs and get the optimal matching between phosphors and LED chips, a novel measurement system and an analytical method for white LED phosphors were proposed.

The Study on Optimal Matching of the Power System;

For the CO 2 short circuit transition welding, the short circuit process is unstable with serious spattering unless the optimum matching between the arc voltage and the welding current is achieved.

In addition,the thesis gives the optimum matching relation among the structure parameters in typical servic regulato

This article is based on the theory of explosive power = force × velocity and Hill\'s Force-Velocity Equation,and obtains the optimum matching value which is corresponding to athletes\' muscle load weight and contraction velocity when the explosive power reaches the athletes\' maximum by adopting method of mathematics.

the presentation centres on the principle of choosing JFET input resistance when the system is in low frequency match; and on the technology of analog feedback for achieving the optimal match of the system.

The optimal match results of traditional way that use MMSE are improved again.

The paper analyzes the conjugate impedance matching principle\'s condition and discusses the optimal load concerning the power amplifer and the transducer,and proposes how to calculate the optimal load.
