Examples
- The enthalpy change on dsc curve suggests that the transition is one from low - ordered state to a higher - ordered state . a stacking mood that the 4 - trifluoro - methyl - 2 , 3 , 5 , 6 - tetrafluorophenylmserts in between two perylene - macrocycles is confirmed by theoretical quantum calculation , such an insertion effect leads to the inversion of ( 0 , 0 ) and ( 0 , 1 ) absorption features under low temperature and the dramatic decrease of exciton coupling , which contributes to the spectral similarity in solution and the solid state
量子化学的计算结果支持氟取代的苯环嵌入两个相邻的?环之间的分子堆砌方式，使得在常温到150左右f - ptcdi固体薄膜的紫外-可见吸收光谱的( 0 ， 0 )和( 0 ， 1 )性状的强度对比发生“反转” ；氟取代苯环的嵌入大大降低激子耦合，使固体吸收光谱性状与溶液类似。 - When the water - air ratio increases , air ' s changing quantity of enthalpy and absolute humid will be enhanced . at last , the paper analyses the data from single factor experiment by mathematics method and gets relationship formulas about the nozzle flux , valid humidifying quantity and air ' s enthalpy changing quantity
最后，对上述单因素试验得到的数据进行数学分析，运用线性回归分析、多项式回归分析和非线性回归分析的数学方法，得到影响撞针型高压小孔径离心式喷嘴的喷嘴流量、有效加湿量和空气焙变量的数学关系式。
