visible ray 【物理學】可見光。

visible signal

In the past few years , scientists have determined that this transparency ? critical for focusing light ? stems in large part from the unique ability of the lens to activate a self - destruct program in its cells that aborts just before completion , leaving empty but sustainable cells that transmit visible rays 過去幾年,專家已確知聚光所必需的透明度,大部份源于水晶體細胞的獨特能力,它們可在發育即將完成時啟動自我摧毀程式,變成中空但能續存的細胞,好讓可見光通過。

Astronomers could gain only a biased idea of the universe when they were limited to the narrow wavelength band of visible rays . 由于只能在可見光的狹窄波段內觀測,天文學家關于宇宙的概念顯然只能是片面的。
