它是三极管放大器的等效电路.It is the equivalent circuit of a triode amplifier circuit.三极管能升高电压.The triode steps up voltage.三极管接法): 中Mu小型灯丝结构.U 4 triode connected: Medium MU small mass filamentary heating structure....
在严重的折皱作用下,摩擦阻力在织物抗折皱能力中仅居次要地位.In severe creasing the frictional resistance plays only a minor role in determining the crease resistance.因此,折皱回复性能是考核织物性能的重要指标之一.So the crease recovery is a one of them.如果隔膜折皱, 则按照前面的步骤更换.I...
