如果函数u=q(t)及v=y(t)都在点t可导,函数z=f(u,v)在 对应点具有连续偏导数,则

一、判断下列说法是否正确,凡对的在括号内打“√”,否则打“×”。 (1)现测得两个共射放大电路空载时的电压放大倍数均为-100,将它们连成两级放大电路,其电压放大倍数应为1000。() (2)阻容耦合多级放大电路各级的Q点相互独立,()它只能放大交流信号。()

6-4电容电容器 一、孤立导体的电容 孤立导体的电容为孤立导体所带电荷Q与其电势V的比值

8.1电荷库仑定律 一、电荷的基本性质 1、电荷的种类:正电荷和负电荷;同性斥、异性吸; 电量q:电荷的多少; 单位:C(库仑) 2、电荷的量子化:任何带电体所带的电量总是电子电量的正负整数倍

#include void maino float a[5], *p, *q;

#include #include void maino float x, y, z, q, area; printf(\请输入三角形的三条边:\)

一、选择题: 1.如图所示,一个带电量为q的点电荷位于立方体的A角上,则通过侧面abcd的电场强度通量等于:
