The benchmark rate is typically the yield-to-maturity on a government bond having the same, or close to the same, time-to-maturity. The spread is the difference between the yield-to-maturity on the new bond and the benchmark rate. The yield spread is the additional compensation required by investors for the difference in the credit risk, liquidity risk, and tax status of the bond relative to the government bond. 问：除了视频里讲的相似三角形法，这里还说了A 可以估利差 spread ，可否简单举例说明？貌似没有讲过
