双联泵图中标注尺寸代号的数值除上表外其余同于单泵。 - All of the pumps which feed the main and auxiliary hydraulic systems are con - nected to , and driven by , a single pump drive transmission ( pdt )
液压泵驱动装置和空气压缩机分别安装在位于公用基底层上一个电动机相反的两端。 - Firstly it spares a large amount of lubricants and reduces the expenses of 1 , 000 yuan for a single pump per year . indiect economic loss of unplaned shutdown caused by nonclearence between bearings and the shafts are accoridingly reduced
首先是节约了大量润滑油，单台泵润滑油损耗每年可减少1000元左右，同时也减少了抱轴次数和影响整个装置循环或非计划停车所造成的间接经济损失。 - Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber . whereas the spectrum of raman gain coefficient of optical fiber is not flat , the gain of signal light with different wavelength induced by a single pump is rather different , when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump , the gain spectrum of the wdm signal light is not flat . the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )
拉曼光纤放大器（ ramanfiberamplifier ,简称rfa ）利用高强度的泵浦光与信号光在光纤中的非线性相互作用实现信号光的直接放大，但是由于光纤的拉曼增益系数谱很不平坦，所以同一泵浦光源对不同波长信号光的增益就存在很大的差别,因此,用单泵浦光源来放大波分复用( wavelengthdivisionmulti - plexing ,简称wdm )信号光时，各信号光的增益值就有很大差异， wdm信号增益的平坦度对光信噪比( opticalsignal - noiseratio ,简称osnr )有重要影响。
