问题 问答题 简答题

简述可保利益原则确定的根据和意义。

答案

参考答案:

利息率和收益率是两个既相互联系,又相互区别的概念。

(1)对于存款来说,由于到期偿还金额与最初投资资本金是一样的,因此利率与收益率是一样的。

(2)但是对于大多数债权凭证来说,由于二级市场价格是波动的,债券参与二级市场交易的话,实现的价值就是不确定的,从而使实现的收益率或高于或低于票面利率。

(3)反映投资者实际获利水平的收益率,可被定义为有效利率,在正常生活中常常被直接称为利率。

     A Yacht Race(帆船赛)Friday 25th June

     The wind has just dropped.

     Everyone is silent and depressed (沮丧的). So far this has been the worst and slowest leg of the race. We still haven't reached the English Channel.  

     Saturday 26th June

     At last We've just passed Land's End.However,with so little wind,we'Il probably take two more days

to reach Southampton. We're all very hungry. We have already finished all our food. Dawn discovered

some emergency rations(给养) -chocolate and glucose (葡萄糖)  tablets (药片) -so now we're eating those. Nobody has complained yet, but I know the girls are feeling quite low. Please God, send us some

wind.

      Monday 28th June 5:30 a. m.

      We can see some yachts waiting to welcome. It feels great but it is sad to think that after so many days we are almost at the end of our journey.

      Monday 28th June 11:45 a. m.

      We've done it! This is the most wonderful day of my life. Now I can rest. I said we could complete the race and we did!
