自五十年代Jones首先定义探测率D以来,D一直是衡量红外探测器性能的最重要参数,这个参数的数值通常是一个很大的数,例如一个探测器的探测率可能是D=2×10~(10)cmHz1/2/W。随着计算机科学和技术的发展及其广泛应用,最近在外刊上出现了用计算机语言表达探测率数值的方法。例如D=2×10~(10)cmHz1/2/W表作D=2 E10cmHz 1/2/W。这种表达法具有明显的优点:正确无误,简单明了,在书写、排版、打字和刻印等方面可省略[×]或[·]号,避免10的乘方所带来的不方便,不易出错。至于便于计算机上应用更是自不待言。
Since Jones first defined the detection rate D in the 1950s, D has always been the most important parameter for measuring the performance of infrared detectors. The value of this parameter is usually a very large number. For example, the detection rate of a detector may be D = 2 × 10 ~ (10) cmHz1 / 2 / W. With the development of computer science and technology and its wide application, the method of using computer language to express the detection rate recently appeared in the foreign media. For example, D = 2 × 10 ~ (10) cmHz1 / 2 / W Table D = 2 E10cmHz 1/2 / W. This method of expression has the obvious advantages of being correct, straightforward, omitting [x] or [·] in writing, typesetting, typing and marking to avoid inconveniences and difficulties in making mistakes in the power of 10 . As for the convenience of computer applications is beyond doubt.
