看程序應該能看懂怎么輸入，我就不寫具體輸入什么了

1.轉動慣量的測定

1.不同物體的擺動周期

#include<iostream> #include<cmath> using namespace std;int main(){double pi=3.14,jzhi=0.187e-4,jjia=0.321e-4;double t0,t1,t2,t3,t4,t5;double k,j1,j0,j11,j2,j22,j3,j33,j4,j44,j5,j55;double m1,m2,m3,m4,m5;double d1,d2o,d2i,d3,d4,d5; cin>>t0>>t1>>t2>>t3>>t4>>t5;cin>>m1>>m2>>m3>>m4>>m5;cin>>d1>>d2o>>d2i>>d3>>d4>>d5;j11=1/8.0*m1*d1*d1;j1=j11;j0=j11*t0*t0/(t1*t1-t0*t0);k=(j1+j0)*4*pi*pi/(t1*t1);j22=1/8.0*m2*(d2o*d2o+d2i*d2i);j2=k*t2*t2/(4*pi*pi)-j0;j33=1/10.0*m3*d3*d3;j3=k*t3*t3/(4*pi*pi)-jzhi;j44=1/12.0*m4*d4*d4;j4=k*t4*t4/(4*pi*pi)-jjia;j55=1/8.0*m5*d5*d5;j5=k*t5*t5/(4*pi*pi)-j0;cout<<k<<endl;cout<<"j2'="<<j22<<";j2="<<j2<<";百分差="<<abs(j22-j2)/j22<<endl;cout<<"j3'="<<j33<<";j3="<<j3<<";百分差="<<abs(j33-j3)/j33<<endl;cout<<"j4'="<<j44<<";j4="<<j4<<";百分差="<<abs(j44-j4)/j44<<endl;cout<<"j5'="<<j55<<";j5="<<j5<<";百分差="<<abs(j55-j5)/j55<<endl;//0.605 0.839 1.245 1.116 2.056 0.959 // //0.385 0.7079 0.8935 0.1350 0.7160 // //10 10 9.382 13.25 61 10 }

2.滑塊質心離軸不同距離的擺動周期

#include<iostream> #include<cmath> using namespace std; int main(){double t1,t2,t3,t4,t5;cin>>t1>>t2>>t3>>t4>>t5;double j11,j22,j33,j44,j55,j1,j2,j3,j4,j5;double pi=3.14,jjia=0.321e-4,m=0.239,j6=0.772e-4;double j0,k,m4=0.135,l=61,t=2.056;j0=1/12.0*m4*l*l;k=(j0+jjia)*4*pi*pi/(t*t);j11=k*t1*t1/(4*pi*pi)-jjia;j22=k*t2*t2/(4*pi*pi)-jjia;j33=k*t3*t3/(4*pi*pi)-jjia;j44=k*t4*t4/(4*pi*pi)-jjia;j55=k*t5*t5/(4*pi*pi)-jjia;j1=j0+j6+2*m*5*5;j2=j0+j6+2*m*10*10;j3=j0+j6+2*m*15*15;j4=j0+j6+2*m*20*20;j5=j0+j6+2*m*25*25;cout<<k<<endl;cout<<"實驗值j="<<j11<<";理論值j'="<<j1<<";百分差="<<abs(j1-j11)/j1<<endl; cout<<"實驗值j="<<j22<<";理論值j'="<<j2<<";百分差="<<abs(j2-j22)/j2<<endl; cout<<"實驗值j="<<j33<<";理論值j'="<<j3<<";百分差="<<abs(j3-j33)/j3<<endl; cout<<"實驗值j="<<j44<<";理論值j'="<<j4<<";百分差="<<abs(j4-j44)/j4<<endl; cout<<"實驗值j="<<j55<<";理論值j'="<<j5<<";百分差="<<abs(j5-j55)/j5<<endl;//2.264 2.918 3.619 4.446 4.866 }

2.密立根油滴實驗

#include<iostream> #include<cmath> using namespace std; int main(){double pi=3.14,p=1.013e5,d=5e-3;double rou=981,g=9.8,kq=1.83e-5,l=1.5e-3,b=8.22e-3;double q,t,u,v,a,a0,e=1.6e-19;int i=1;while(cin>>t>>u){cout<<"text: "<<i<<endl;v=l/t;a0=sqrt( (9*kq*v)/(2*rou*g) );a=sqrt((9*kq*v)/(2*rou*g*(1+b/(p*a0))) );double q1=18*pi/sqrt(2*rou*g);double q2=pow(kq*l/(t*(1+b/p*a)),3.0/2);double q3=d/u;double q=q1*q2*q3;cout<<"q= "<<q<<endl;cout<<"電荷數= "<<q/e<<endl;cout<<"基本電荷測量值= "<<q/((int)(q/e))<<endl; i++;}}
