Social customs and ethics are the things which are not determined by one or two factors but synthesizing many factors 但是社會傳統并不是科技的單值函數,它還受到其他因素的影響。
The average temperature of supply water and backwater only is single function of extraventricular temperature . so only it can reflect radiator ' s emitting heat , heat net supplying heat and user ' s heat load 只有二次網供回水平均溫度是室外溫度的單值函數,即它能反映用戶熱負荷、散熱器散熱量、熱網供熱量的大小。
The chosen controlled parameter must be single function of extraventricular temperature because extraventricular temperature affect immediately radiator ' s emitting heat , heat net supplying heat and user ' s heat load . but the sometime chosen controlled parameters all are ' t extraventricular temperature ' s single function 室外溫度的變化直接影響用戶熱負荷、散熱器散熱量、熱網供熱量的大小,所以選擇的被控參數應與室外溫度有單值函數關系,而以往所選的被控參數與室外溫度之間都不是單值函數關系。
