Chemical equivalence refers to drug products that contain the same compound in the same amount and that meet current official standards; however, inactive ingredients in drug products may differ. 化学等值是指药物制品中含有等量的同一主药并符合现行法定标准,而其中的非活性成分则可以不等。
In addition, an auto-ignition model based on the multi-step DME/ air chemical kinetic mechanism was developed and an ignition delay data library was generated using the computational results of DME ignition delay correlated against temperature, pressure and fuel/ air equivalence ratio. 另从二甲醚低温着火的化学反应机理入手,开展了其自燃着火过程的数值模拟研究,进而建立了计及温度、压力和燃空当量比因素的DME滞燃期数据库;
All of glass transition temperature, peel strength, shear strength, chemical composition, surface structure and surface carbon content show a good time-temperature equivalence characteristic between humidity aging time and temperature when the adhesive is exposed to heat ageing or humidity and heat ageing. 胶粘剂在热老化和湿热老化条件下,玻璃化温度,剥离强度、剪切强度、化学组成、表面形貌和表面碳元素组成等具有时温等效性。
