Using the radiation distribution function, the temperature distribution in the pyroelectric crystal is equivalent power of pyroelectric detectors are computed and the result of …
文中提出等效噪声功率谱密度的概念。
The concept of "equivalent noisy power spectral density" is introduced in this paper.
根据冷却的实际需要自动调节风扇的转速，不仅可降低功率消耗、节省燃油，而且还可以达到降低噪声、延长发动机寿命等效果。
Automatically modulating the fan's rotational speed according to cooling requirement can not only reduce the power and fuel consumptions, but also reduce noise level and prolong the engine's lifetime.
通过实验探讨了APD的温度特性，得到了APD的雪崩电压、暗电流、光电流、等效噪声功率与温度的关系。
Experiments were done to probe into the characteristics of APD. The relationships between avalanche voltage, dark current, photocurrent, NEP and temperature were educed separately.
