查询词典 Ra

The offset current is low, so the current flowing through RA and RB is the same. Assuming the gain is very high, the voltage gain of the circuit is defined as

由于偏置电流很低，所以流过RA 和RB 的电流相同，假定增益A非常高，则电路的电压增益为

Surface morphology, microstructure and wear morphology of the coatings were investigated using model KYKY-2800 scanning electron microscope modeled. Phases of the coatings were analyzed using model D/max-RA X-ray diffractometer. Microhardness of the coatings was tested using model MH-6 hardness-testing device. The wear-resisting property of coatings was compared with 65Mn steel treated by the quenching and backfiring technology using the home-made abrasion machine. The feasibility was analyzed for reactive electric-spark build-up welding TiN cermet coating to be used for gear shaft restoration.

采用KYKY-2800型扫描电镜观察了堆焊层表面形貌、显微组织和磨损形貌，采用D/max-RA型X 射线衍射仪分析了堆焊层物相，采用MH-6型显微硬度计测定了堆焊层显微硬度，采用自制磨损实验机对比了堆焊层与淬火回火65 Mn钢的磨损性能，分析了电火花堆焊TiN金属陶瓷层用于轴颈修复的可行性。
