T is a capital letter, or upper case, and t is lower case. T是大写字母,或叫大写字母盘;t是小写字母盘。
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。
This paper explains the basic concept of possible non-coherence in transmission systems and provides a case study where compared to a single transmission line structure with loop-in connection, a double transmission line structure with tap-connection not only requires one more line but also has a lower reliability level. 在该实例中,一个双回线并行结构通过分支点T接引入变电站,与一个单回线结构通过分段接入变电站相比,不仅多需要一条线路,而且可靠性也差。
