Q Trace this letter first, then color the matchable upper and lower case letters. 首先按线描好字母,然后将匹配的字母大小写的框内区域图成相同颜色。
The position of the interface hf, flow rate Q, lower and upper level temperature T_2 and T_1 were investigated with thermal plume theory in the case of buoyancy force and buoyancy force assisted by wind. 分别考虑热压单独作用以及热压和风压相互加强作用的情况,用热羽流理论研究室内热分层高度hf,自然通风量Q,上、下层温度T2、T1的影响因素。
And lower case q sub2 is the charge on the electron. 小写q加个下标2是指电子所带电量。
I am going to highlight this by calling this q1, lower case q being the charge here on the nucleus. 我要把它称作q1来进行强调,小写q是指原子核上的电量。
