解: 当E单独作用时E-|||-10-|||-I2=-|||-A=1A-|||-R2+R35+5U'S=I'2R2=1×5V=5V当U-|||-S单独作用时R3-|||-5-|||-T2=-|||-R2+R3-|||-S-|||-×1=0.5A-|||-5+5US=I2R2=0.5×5V=2.5V所以,由叠加定理有I2=12-12=1A-0.5A=0.5AUS=U'S+U'S=5V+2.5V=7.5V 结果...
IS100是特异性地出现在鼠疫菌和假结核耶尔森菌中的插入序列,它在鼠疫耶尔森菌的染色体中有多个拷贝,在质粒中也有分布.它的转座活性较高,致使鼠疫菌中出现多个假基因,同向IS100之间的同源重组可以导致鼠疫菌发生基因的水平转移.doi:10.3969/j.issn.1003-4692.2005.02.032李丽娜中国疾病预防控制中心传染病预防控制所人...
解析 电路中有两个电源作用,根据叠加原理可设 U_a=E_1U_a+K_2I_s 当U =1V、 =1A时,得 0=I_1*1+I_2*17 当U s=10v.I_s=0 A时,得 1=x_1*10+x_2*0 联立两式解得: K_1=a1,K_2=-0.1 所以 U_0=I_1U_3+I_3I_3 =0.1 ×0+(-0.1)×10=-1V ...

现在你需要把你的电路图给我发过来，我才可以讲解 不要着急 咱们先去判断这个线路的结构 这个电路是不是r2与r3r4串联之后？然后再并联 那我们分别把这个电阻求出来 2324串联是100欧，然后再与R2并联 因为他还有一个反向电流，所以我们要求反向电流在23电流，然后计算出23总电流之后就是本道题的答案 ...
