不要靠近那个变压器.Keep away from the transformer.变压器可在两个晶体管之间隔离直流 偏压.The transformer isolates the transistors with regard to d - c bias voltage .降压变压器 的匝数比小于1.A step - down transformer has a turns ratio less than 1....
这些结构通常是斜交的,而横隔板则垂直于纵梁布置.These structures were usually skewed with the diaphragms placed perpendicular to the longitudinal girders.斜交桥由相互斜交的主梁、梁及桥面板组成,结构受力复杂.Obique bridge is made up of main girder crossbeam and bridge fl...
