DRF

The obtained DRF confirmed the dominant effect of dry deposition of SO2 on atmospheric corrosion of materials at most sites .

通过对剂量&响应函数的定量分析还表明，在绝大多数研究站点，SO2干沉降对材料的大气腐蚀起了主导作用；

Merger of DEA and DRF Method

DEA与DRF法的整合

Supranormal DRF exists and represents the true split function of the affected renal unit in patients with adequate renal parenchyma ;

结论：异常DRF的出现代表着患者相当肾实质受影响肾单位的真正分肾功能；

In the partial slip regime ( PSR ), the fatigue cracks very easily initiated and mainly propagated parallel to the surface under the action of DRF . And the local fatigue was main damage formal in this regime .

在部分滑移区，复合微动作用下极易导致疲劳裂纹的萌生并主要沿平行于接触表面方向扩展，该区域微动损伤主要表现为局部疲劳。

This text is aimed at utilizing DEA model to while we are carrying on validity appraisal . It proposes the appraising combined with both DEA method and the analytic approach of the factor ( abbreviated as DRF method ), thus improving DEA method .

本文针对利用DEA模型进行有效性评价时碰到问题，提出了用因子分析法（简称DRF法）与DEA法相结合来进行评价，这是对DEA法的一种改进。

Regarding fluctuating wind as white noise excitation and using Davenport wind speed spectrum respectively , based on the building load code ( GBJ9-87 ), the dynamic reduction factors ( DRF 1 and DRF 2 ) for the tall steel structure_TMD system have been formulated .

分别将脉动风视为白噪声和采用Davenport风速谱，基于建筑荷载规范GBJ9-87，导出了高层钢结构TMD系统减振系数DRF1和DRF2。
