for i=2:n-1
[B]var1(i) = (1-0.5/(i-1));
var2(i) = (1+0.5/(i-1));[/B]
fT(i) = F(i)+ ( M/2*(var1(i)*T(i-1)+var2(i)*T(i+1))-b1/2*dz*rc(i) )/(M+1) - T(i); % formula (20)
fx(i) = G(i)+ ( M1/2*(var1(i)*x(i-1)+var2(i)*x(i+1))+b2/2*dz*rc(i) )/(M1+1) - x(i); % formula (21)
end

谁能帮我翻译下这段语句什么意思呢？尤其是加黑那段

谢谢谢谢啦
