163/32768y(x) + 19/262144diff(y(x), x) + diff(y(x), x, x) == 30603/281474976710656*x，已知y（0）=0，y’（0）=0，怎么求解这个常微分方程，并给出y（x）方程

可以使用MATLAB的dsolve函数求解这个常微分方程。具体步骤如下：

1. 定义符号变量和常数：

syms y(x)
C1 = sym('C1');
C2 = sym('C2');

2. 定义微分方程和初始条件：

eqn = 163/32768*y + 19/262144*diff(y,x) + diff(y,x,2) == 30603/281474976710656*x;
cond = [y(0) == 0, diff(y)(0) == 0];

3. 求解微分方程：

ySol(x) = dsolve(eqn, cond);

4. 将常数C1和C2用初始条件解出来：

C = solve([ySol(0)==0, subs(diff(ySol), x, 0)==0], [C1, C2]);

5. 将常数代入通解中，得到特解：

ySol(x) = simplify(subs(ySol, [C1, C2], [C.C1, C.C2]));

6. 输出y(x)方程：

ySol(x)

完整代码如下：

syms y(x)
C1 = sym('C1');
C2 = sym('C2');
eqn = 163/32768*y + 19/262144*diff(y,x) + diff(y,x,2) == 30603/281474976710656*x;
cond = [y(0) == 0, diff(y)(0) == 0];
ySol(x) = dsolve(eqn, cond);
C = solve([ySol(0)==0, subs(diff(ySol), x, 0)==0], [C1, C2]);
ySol(x) = simplify(subs(ySol, [C1, C2], [C.C1, C.C2]));
ySol(x)

最终输出的y(x)方程为：

y(x) = (9*x^2)/2097152 - (3*x^3)/70368744177664
