朝功穆斯林的五项宗教功课之一。 朝功,就是到麦加朝觐天房—克尔白圣殿。伊斯兰教规定,每个穆斯林,只要身体健康、经济条件许可、旅途平安,一生中至少要到麦加朝觐一次。凡去朝觐过的,即被尊称为哈吉。除麦加外,麦地那和耶路撒冷也是伊斯兰教的圣地。
因此这里,是大于零的,q2,is,greater,than,zero。,功也大于零,也大于零,and,minus,q1,is,greater,than,zero,热量的流向,是朝这个方向。
So here, q2 The work is greater than zero, q1 that is heat is flowing this way.
如果方向相同,都朝这里或那里,功就大于。
If they're in the same direction, either this way or that way, 0 then the work is larger than zero.
