名义收益率是债券或其他证券发行时所标明的固定收益率。这个收益率是按照年化计算的，也就是说，将债券或其他证券的利息或分红转换成等效的年化收益率。

名义收益率的计算公式为：名义收益率 = （债券年利息收入 + 债券市场价格变化）/ 债券市场价格 × 100%。其中，债券年利息收入是指债券持有人每年获得的利息，债券市场价格变化是指债券价格在发行后的波动。

名义收益率越高，说明投资者在购买债券或其他证券时获得的投资回报率越高。因此，投资者在选择债券或其他证券时，会关注名义收益率这一指标。

此外，名义收益率还可以用于比较不同投资产品的投资回报率。例如，投资者可以通过比较不同债券的名义收益率，来选择投资回报率更高的债券。

总之，名义收益率是衡量投资者在购买债券或其他证券时获得的投资回报率的重要指标，对于投资者进行投资决策具有重要意义。

The nominal yield is the fixed yield stated at the time of issuance of bonds or other securities. This yield is calculated on an annualized basis, which means that the interest or dividends of the bond or other securities are converted into an equivalent annualized yield.

The calculation formula of the nominal yield is: nominal yield = (annual interest income of bond + bond market price change) / bond market price × 100%. Among them, the annual interest income of bond refers to the interest income that bond holders obtain every year, and the bond market price change refers to the fluctuation of bond prices after issuance.

The higher the nominal yield is, the higher the investment return rate that investors obtain when purchasing bonds or other securities is. Therefore, investors will pay attention to the nominal yield when choosing bonds or other securities.

In addition, the nominal yield can also be used to compare the investment return rates of different investment products. For example, investors can compare the nominal yields of different bonds to choose the bond with a higher investment return rate.

In general, the nominal yield is an important indicator to measure the investment return rate that investors obtain when purchasing bonds or other securities, and it is of great significance for investors to make investment decisions.
