1、A convex lens is used to concentrate rays of light.
凸透鏡用于聚集光線。

2、Just as a double convex lens enlarges, so a double concave lens reduces
正象雙凸透鏡可以放大那樣，雙凹透鏡也可以縮小。

3、a single convex lens is used to produce an enlarged image.
能夠產(chǎn)生放大圖像的單個凸透鏡。

4、Just AS a double convex lens enlarges, so a double concave lens reduces.
正象雙凸透鏡可以放大那樣，雙凹透鏡也可以縮小。

5、Just as a double convex lens enlarges so a double concave lens reduces.

7、Wearing lower degree convex lens can reduce incidence rate of myopia in primary school students.
配戴低度凸透鏡可降低小學生近視的發(fā)生率。

8、In this paper, a measuring method of convex lens foci in collimator is given.
介紹一種測量平行光管內(nèi)凸透鏡焦距的測量方法。

9、A convex lens causes rays to converge on a single point, the focal point.
會聚透鏡使光線會聚于一點，即焦點。

10、A convex lens is thicker at its center than its periphery. It causes rays to converge.
凸透鏡中心部分比周圍要厚，它使光線會聚。
