kfr

For KFR type air-conditioner, if refrigeration normal, not heating, its fault mainly in four electromagnetic valve or its control circuit.

对于KFR型空调器，若制冷正常，而不制热，其故障主要发生在四通电磁阀或其控制电路。

Based on central field approximation and modified Keldysh Faisal Reiss ( KFR) theory, with the consideration of the effects of the residual ion on the final photoelectron, an expression of ATI differential probability of atoms in strong laser fields is obtained.

在中心场理论的基础上，利用改进的KFR方法，考虑到残留离子势对末态光电子的影响，推导出了原子在强激光场中超阈值电离微分跃迁几率的解析表达式。

The first case is an8 year-old female from Kfr Elsheikh district, Kfr Elsheikh Governorate.

第一个病例是Kfr Elsheikh省Kfr Elsheikh区一名8岁女童。

With this staining procedure, the optimal staining results were obtained for KF-1, KFr, HeLa and IK-90 cell lines.

本实验室将KF-1、KFr、HeLa、IK-90等几种培养细胞系用此方法染色均可获得满意的染色结果。
