1·The number of lumens a bulb produces for each watt it consumes.
一个灯管消耗每单位瓦特所产生的流明数。
2·So if a 100-watt incandescent produces 1, 700 lumens, and a 20-watt LED does the same, the LED will be sold as a 100-watt equivalent.
所以如果一个10 0瓦的白炽灯产生1,700流明，一个20瓦的LED也产生同样亮度，那么就说这个LED灯相当于100瓦白炽灯。
3·While the upper limit for incandescent lamps is 52 lumens per watt, that is the theoretical luminosity of tungsten at its melting point.
虽然白炽灯的发光效率极限是每瓦52流明，然而这钨丝在其熔点的理论亮度。
4·Despite a worst-in-test 700 lumens (claimed) on a 14-watt draw, the EcoSmart didn’t seem particularly dim. And the globelike casing around the coil gave this CFL a nice, even glow.
虽然在测试中表现出700流明的最差亮度（耗电14瓦），其实并不是特别的暗。
5·If people want to replace their old power-hungry incandescent bulbs with CFLs or LEDs good for 45 lumens per watt, all the better.
如果人们想要把他们的高耗能白炽灯换成45每瓦流明的CFLs灯或者LEDs灯，那就再好不过了。
1·A technique for forcing fillers into lumens of reed fibers through pits was studied.
利用高速搅拌的方法研究了通过纹孔将填料加入芦苇纤维细胞腔的技术。
2·On the 18th day of embryo, there were PAS positive colloids in the follicle lumens and the mature thyroid follicles were formed.
滤泡腔内出现PAS反应阳性胶体，成熟的甲状腺滤泡结构基本形成。
3·Methods Found the relationship of aortic dissection false lumens ectonexine of aortic tunica media by test and measurement their shape-changed strength ratio.
方法通过胸主动脉夹层假腔内外层的屈服形状改变比能，发现两者间的关系。结果60%的实验犬形成夹层模型。
