Question

英文翻译 高手进来帮下忙 谢谢

E=∑:
t=l
Rt - It - At - Tt + Pn - GT - UM
(l+r)t (l+r)n
Where E = equity
Rt = net annual cash flow in period t
It = interest on mortgage in period t
At = amortization of mortgage in period t Tt = income tax in period t
Pn = selling price at end of period t = n
GT = capital gains tax payable upon sale of property in year t = n UM = unamortized mortgage in year t = n
n = investment horizon, in years from the present
r = internal rate of return

Answer 1

E=∑:
t=l
Rt - It - At - Tt + Pn - GT - UM
(l+r)t (l+r)n
当 E = 抵押资产的净值
Rt = 每年现金流净值t
It = 一定阶段抵押贷款利息t
At = 一定阶段分期偿还t Tt = 一定阶段收入税t
Pn = 年终销售价t = n
GT = 建立在销售额上的资本收入税t = n UM = 一定阶段非分期偿还贷款金额t = n
n = 投资水平, 从现在开始的若干年里

一定阶段可能都指的是一年。

r = 内部返还率

翻译的术语不很专业，见谅。
