adj.多變的;[昆]多花采蜜的;多花采粉的
Coordinates and processes in the good teaching appraisal a Yuannatural and the polytropic value orientation relations. 協(xié)調(diào)和處理好教學評價中一元性與多元性價值取向的關(guān)系。
Deeply grasp the relationship between the basic properties, such as p 、 v 、 T during polytropic process. 掌握多變過程系統(tǒng)與外界交換的熱量、功量的計算。
Air compressors can have high efficiencies;around 90% polytropic at their design conditions. 國內(nèi)許多企業(yè)和高校都在大力推動弱電系統(tǒng)理論的學習和應用。
In the whole polytropic process, whenever V increases or decreases,system eitherpurely absorbs or purely releases heat, unless Q=0. 對多方過程,當V增大或減少時,要么全部Q=0,要么全部過程吸熱或放熱.而對非多方過程,熱容量是變量,其吸、放熱比較復雜
