用latex表示:∂I/∂x=3 (W_2 h_2 (20-x))/√(〖(h_2^2+〖(20-x)〗^2)〗^5 )-3 (W_1 h_1 x)/√(〖(h_1^2+x^2)〗^5 )= (-30(20-√2 h))/√(〖(25+x^2)〗^5 )+(9h_2 (20-x))/√(〖(h_2^2+〖(20-x)〗^2)〗^5 )=0

$$\frac{\partial I}{\partial x} = 3\left(\frac{W_2h_2(20-x)}{\sqrt{\left(h_2^2+(20-x)^2\right)^5}} - \frac{W_1h_1x}{\sqrt{\left(h_1^2+x^2\right)^5}}\right) = -\frac{30(20-\sqrt{2}h)}{\sqrt{\left(25+x^2\right)^5}} + \frac{9h_2(20-x)}{\sqrt{\left(h_2^2+(20-x)^2\right)^5}} = 0$$
