问题如下：
Relative to a fully amortized bond, the coupon payments of an otherwise similar partially amortized bond are
选项：
A.
lower or equal.
B.
equal.
C.
higher or equal.
解释：
Correct Answer: C
Except at maturity, the principal repayments are lower for a partially
amortized bond than for an otherwise similar fully amortized bond.
Consequently, the principal amounts outstanding and, therefore, the amounts of
interest payments are higher for a partially amortized bond than for a fully
amortized bond, all else equal. The only exception is the first interest
payment, which is the same for both repayment structures. This is because no principal
repayment has been made by the time the first coupon is paid.
coupon payment = coupon rate x par value这个公式不是一直有效的吗？本金是否摊销喝coupon没有关系吧
