汉语拼音:tòu jìng
一种简单的光学仪器。由透明物质(玻璃、水晶等)制成。光线通过透镜折射后可以成像。一般分为凹透镜和凸透镜两大类。凹透镜中央部分比边缘部分薄,能使光线发散,如近视眼镜片;凸透镜中央部分比边缘部分厚,能使光线会聚,如远视眼镜片。
and a fourth lens formed of a biconcave lens having aspheric surfaces on both sides and an inflection point on an upper aspheric surface.
第四透镜,由双凹透镜形成,在两侧上具有非球面表面,在非球面表面上具有拐点。But gravitational lensing had never before been used in such a precise way.
但是引力透镜还从未以如此精确的方法被使用过。He took the glass and focused the sun on some dried wood.
他拿出透镜,然后把太阳光聚焦在一些干木材上。In measuring the focal distance of lens, the experimental accuracy is often affected by the poor quality in the formation of images.
在测量透镜焦距时,往往由于成像质量差而影响实验的精度。This energy is eventually released to flow on magnetic field lines to the Sun, which transmits it like a lens to all the planets.
这个能量被最后释放以磁场线扰动到达太阳,太阳像一个透镜那样将它传送到所有的行星上。Astronomers measure how much dark matter lies in galaxies by a fluke of physics called gravitational lensing.
天文学家通过一种叫做引力透镜效应的物理现象来测算星系中暗物质的质量。Some telescopes do not use a lens at the front. They use a curved mirror at the back. A curved mirror is better than a lens in some ways.
一些望远镜的前部不用透镜,而在后面装上一个曲面镜,曲面镜在某些方面要比透镜好。Light traveling through the matter clump is warped and distorted, a phenomenon called gravitational lensing.
当光线穿过这些物质团块的时候就会发生弯曲或扭转,这种现象被称为“引力透镜效应”。A "gravitational lens" of this type could be powerful enough to map the continents and oceans of a planet in a distant star system.
此类“引力透镜”的放大倍数可能足以映现遥远星系中一颗行星的大陆和海洋。
