SD rats were divided into 3 groups: control, scald and electret group. 将大鼠分成对照组、烫伤组和驻极体实验组。
The special noise cancelling electret or dynamic microphone guarantees clear communications in all conditions. 特殊的噪声消除电容或动圈麦克风保证了各种条件下的清晰通话。
The film electret has two times high piezoelectricity (d33=31pC/N) than PVDF (d33=1 5pC/N). 使用介电谐振谱测量的双层膜的压电d33系数(31pC/N)是传统的铁电聚合物材料PVDF相应值(15 pC/N)的2倍左右。
The meltblown nonworen technology,the electret theory and the electret nonwoven are introduced in this paper. 系统介绍了非织造布熔喷工艺、驻极化理论以及驻极体非织造布。
Conclusion: Negative electret can be used as an enhancer for transdermal permeation of meloxicam. 结论:负极性驻极体可以作为美洛昔康透皮吸收的一个促进因子。
In this article,physical enhancement especially using electret will be mainly discussed. 本文主要介绍驻极体透皮给药制剂的研究进展及其相关透皮机理。
