Such events, which only blot out the middle of the Sun, are known as annulareclipses.
像这样,太阳中部被遮盖的天象,就叫做日环食。

Usually annulareclipses are referred to solar eclipses, as Earth's umbral shadow is always large enough for the whole Moon to hide inside during a lunar eclipse.
在日月食中,因为地球的影子比月球大得多,所以只会有日环食而没有月环食。

In addition to partial eclipses, sky-watchers may see two other types of solar eclipses in a given year: total and annular.
