散粒噪声 meaning in English
shot noise
Examples
- Our second concern is with shot noise .
第二个要讨论的是散粒噪声。 - Signal shot noise
散粒噪声 - 3 . the fully inseparable bright tripartite entangled state ( tes ) was experimentally generated using the nopa at deamplification and the linear optical system consisting of polarization beam splitters and half wave plates
实验测定的这两个起伏方差分龙要别较散粒噪声极限降低3 . 28dbm和3 . 18dbm 。 - After ameliorate the hardware of the spectrometer , there are many kinds of noise added to the system inevitably . they are hot - noise and disperse - noise in electron circuitry and the wavelength excursion due to the grating turning
光谱仪经过硬件改造以后，不可避免地将电子方面的噪声带入到系统中，其中主要包括电子线路中的热噪声和散粒噪声（白噪声）以及光栅转动过程中的机械误差引起的波长漂移。 - Abstract : to against the fact of the commercial available white noise generators are very expensive which is not good for general operations , a simple and effective limited band white noise generator is design . the generator is using the feature of dual polarity transistor , i . e . , the power spectrurn density of particulate noise is not related to frequency in very wide band and close to white noise . the concrete circuit is also given
文摘:针对市售白噪声发生器价格昂贵，不利于一般场合使用的问题，介绍利用双极性晶体管散粒噪声功率谱密度在非常宽的范围内与频率无关，属白噪声这一特性，设计了一种简捷、有效的限带白噪声发生器，并给出了具体电路。
