老师您好，麻烦您解释下这句话好么？“With a downward-sloping term structure of yield volatility, short-term bonds will not always experience greater price fluctuation than long-term bonds. ”为什么说收益率波动曲线斜向下，所以短期债券价格波动不会一直比长期的大？收益率波动曲线与债券价格之间的逻辑是什么？

老师您好，麻烦问一下，图1图2都是收益率波动曲线？（图1来自Yield volatility, Credit and liquidity Spread课程）如果两张均为收益率波动曲线，那两者出现分别是在什么情况下?或者说，是什么导致了两者的不同？ 谢谢。
