查询词典 ambient

In traditional design for a wire-tube type condenser, the air's temperature around it is considered to be the ambient temperature. In fact, the air's temperature is affected by the distance between the refrigerator's back and the wall and is heated by the compressor and condenser, so its temperature is not equal to the ambient temperature. In this case, the traditional design method is not accurate.

传统的设计冷凝器的方法，是把丝管式冷凝器周围空气的温度当作环境温度，而实际上，由于受压缩机散热、冷凝器加热、冰箱后壁和墙壁之间的间距的影响，冷凝器周围空气的温度并不等于环境温度，因而传统的设计方法并不精确，为了保证设计的精确性，有必要对冷凝器周围空气的温度进行研究。

Based on the analysis of micro -bolometer resistance -temperature characteristics, a new readout circuit was proposed. It allowed micro -bolometer operate without a temperature stabilizer over a wide range of ambient temperature. And it need a Flash memory to store the correcting factors of different temperatures and a temperature sensor to detect the ambient temperature of the micro -bolometer. By utilizing the factors in the Flash memory, Digital Analog Converter controls the micro -bolometer bias current to compensate the fluctuation of ambient temperature.

Firstly, this paper investigated roundly the basic theory of the ambient vibration method, analyzed systematically the main methods of ambient vibration identification, and discussed their advantages and disadvantages. Then we established the finite element model of structural dynamics and test model and analyzed their mutual relation, improved MUSIC method and correlation function method in the harmonic identification, and gave the subspace method and correlation function method based on continuous model, which is multi-harmonic retrieve technique. And then, this paper also puts forward least-squares method to estimate directly structural physical and modal parameters; this approach replaced the derivative operator in the continuous time model with an equivalent approximation, and estimated the physical parameters of structures by the least-squares method. And then, we discussed the approximation methods of derivative and their convergence. Finally, this paper researched the modal parameters of a frame structure by the simulation and test. The results demonstrated that subspace method, correlation function method and the least-squares method are effective and stable respectively.

The principle of work is: When ambient temperature rises, the pressure of the SF6 gas increases, drives the indicator along the clockwise rotation, but at the same time, the mouth of the bimetal compensation system "the U shape" publicizes, then impels the indicator to the counter clockwise rotation, when two kind of strength be equilibrium, the ambient temperature change cannot made the indicator deflection.

工作原理是：当环境温度上升时，虽然容器内SF6气体的密度未发生变化但其压力增大，带动指针顺时方向转动，而当温度上升时，双金属补偿装置的"U形"口张大，则推动指针向逆时针方向转动，当两种运动引起表针的偏转量相抵销时，无论环境温度如何变化，指针都不会发生偏转。

Otherwise, When ambient temperature falls, the pressure of the SF6 gas decreases, drives the indicator counter the clockwise rotation, but at the same time, the mouth of the bimetal compensation system "the U shape" reduces, then impels the indicator to along the clockwise rotation, when two kind of strength be equilibrium, the ambient tempera

反之，当环境温度下降时，虽然容器内SF6 气体的密度未发生变化但其压力减小，带动指针向逆时方向转动，而当温度下降时，双金属补偿装置的"U 形"口缩小，则推动指针向顺时针方向转动，当两种可运动个起表针的偏转量相抵销时，无论环境温度如何变化，指针都不会发生偏转。
