本文提出一种新方法——密度矩和法，用底片上已知亮度恒星的PDS测微密度数据来同时决定底片特性曲线和星等零点。

A new method is suggested for determining the characteristic curve of a plate, as well as the magnitude zero point, using PDS microdensitometer data of stars of known brightness on the plate.

夏普，它的一个竞争对手，最近说已开发出了新的微制造技术，用来制造迄今为止功率密度最高的DMFC。

Sharp, one of its rivals, recently said that it had developed new microfabrication techniques to build DMFCs with the highest power densities yet achieved.

根据加西亚博士的说法，这意味着微中子可以像穿过人体的X光一样，用于将密度较大的岩石和较轻的岩石区分开来。

That means they can, according to Dr Gonzalez-Garcia, be used like X-rays passing through a human body, to pick out denser rocks from lighter ones.
