injection noise 中文意思是什麼
injection noise
解釋
噴注噪聲-
The investigation has declared that the fuel injection with bq fuel pump had higher injection pressure, bigger fuel supply rate and shouter fuel supply duration, which would cause the fuel injection quantity and the fule - air mixture to increase during ignition delay period, the pre - mixed combustion to become acutely, and finally result in increased power levels of noise

The other has two metal - insulator - semiconductor ( ms ) contacts with lower leakage current ( less than 4 pa, 300v ) and better energy resolution ( about 10 % fwhm for 241am 59. 5kev line ) and poor working stability. in theoretical studies, the analysis on the phase equilibrium in the vapor growth of cdse single crystals shows that the stoichiometry of cdse crystals can be controlled effectively by controlling the stoichiometry of starting materials and the vapor growth temperature. besides, the investigation of the transporting properties of charge carries in cdse detectors indicates that the noise in energy spectrum detected by using the detectors with msm structure is caused by the hole injection, which is induced by electron injection and the light injection

It can be deduced from the characteristics of ilpll circuit that injection - locking bandwidth is not only related to the injection - locking bandwidth without feedback loop, but also related to the characteristics of frequency mixing, loop gain and the change of the loop phase. thus, the needed bandwidth can be obtained by adjusting the loop parameters. and the phase noise characteristics are mainly determined by loop transmission factor
由ilpll電路特性的推導得出:注入鎖定帶寬不僅跟開環時的注鎖帶寬有關，而且與混頻特性、環路增益以及環路相位變化相關聯，可以通過調節環路的參數得到所需帶寬;相噪特性主要由環路傳輸因子決定，可以通過調節環路濾波得到比開環注入鎖定相噪更優的特性。 -
