据美国国家航空和宇航局研究报告61391号(NASA-CR-61391)摘要称:约塔工程公司已制造了八种可携式荧光灯(据过去报导,用于宇宙空间实验室——译注),还生产了三种试制品,其中两种已达到了物理方面和操作方面的新要求。这是狭缝式的荧光灯,狭缝和反射器的安排使光不致散射而是按照要求集中发射。这样灯光更加强了。用铟汞齐控制汞汽压,使灯在
According to the NASA Research Report No. 61391 (NASA-CR-61391), abstract: Yotta Engineering Corporation has manufactured eight portable fluorescent lamps (reported in the past for use in the Space Lab) Three prototypes were also produced, two of which met the new physical and operational requirements. This is a slit-type fluorescent lamp, the arrangement of the slit and the reflector does not scatter the light but concentrates the emission as required. This light is stronger. With indium amalgam control mercury vapor pressure, the lamp in
