1·Higher melting point.
更高的熔点。
2·To have a useful life, even the hottest quartz-halogen incandescents have to operate well below the filament's melting point.
为了在日常生活中达到效用，连最热的石英卤素灯运行时也不得不适当地低于其灯丝的熔点。
3·That cyclo prefix means that unlike standard alkanes, which come in chains, this one's a ring. The shape gives cycloalkanes a higher melting point.
当“环”这个前缀出现时我们就知道这个烷烃的分子结构不同于普通链状烷烃，他是环装的，因此也有着更高的熔点。
4·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。
5·They do it close to the melting point, so you're actually looking at the sublimation of RDX.
人们一般在RDX的熔点处测量，所以我们实际上在观察rdx的升华。
