一种新的散射光能谱法测量颗粒粒径的方法

中国激光 1998年第10期25卷 897-900页

作者：王乃宁徐贯东上海理工大学动力工程学院温州师范学院物理系

基于光散射原理，提出了一种新的测量颗粒粒径大小及分布的方法。与传统的光散射式激光测粒仪不同，本方法以白色光为光源，仅采集一个空间立体角内的散射光能信号，经反演算后求得被测颗粒的粒径及其分布。给出了这一方法的理论分析、... 详细信息

An in situ measurement setup is established to investigate the photoinduced degradation effects in a controllable inert gas ambient environment for the two different microstructures of poly（3-hexylthiophene）（P3HT） and [6,6]-phenyl-C61- butyricacid methyl ester （PCBM） bulk-heterojunction organic solar cells. The two devices are fabricated with the solvent vapor drying process followed by a thermal annealing （vapor drying device） and only a normal thermal annealing process （control device）, respectively. Their power conversion efficiencies （PCEs） and aging features are compared. Their different degradation behaviors in light absorption are confirmed. In addition, irradiation-induced changes in both nanostructure and surface morphology of the P3HT：PCBM blend films treated with two different fabrication processes are observed through scanning electron microscopy and atomic force microscopy. Aggregated bulbs are observed at the surfaces for control devices after light irradiation for 50 h, while the vapor drying devices exhibit smooth film surfaces, and the corresponding device features are not easy to degrade under the aging measurement. Thus the devices having solvent vapor drying and thermal annealing show better device stabilities than those having only the thermal annealing process.

作者：赵敏光徐济安白贵儒 department of Physics Sichuan teachers college Chengdu Institute of Physics Academia Sinica Beijing University of Science and technology of china Hefei

A d-orbital theory containing nephelauxetic effcet is presented. The optical spectra ofthe free ion Cr3+, the d-d transition, ESR, and the high-pressure spectra are investigatedtheoretically by utilizing a double zeta 3d-radial wave function model for the dn-configura-tion. Calculation results are in good agreement with the experimental data.

Background Burn-out among doctors threatens their own health, and that of their patients. To identify risk factors of the doctor burn-out is vital to improving their health and increasing the quality of healthcare services. This study aims to explore the relationship between work-family confict （WFC） and burn-out among Chinese doctors and the mediating role of coping styles in this *** A cross-sectional survey was conducted in china, with a questionnaire packet which consisted of the Chinese Maslach Burnout Inventory （CMBI）, WFC Scale and the Simplifed Coping Style Questionnaire （SCSQ）. A total of 2.30 doctors participated in the survey. Correlation analysis was performed to explore the relationship between CMBI, WFC and SCSQ scores. A linear regression model was set to determine the mediating role of coping styles on the relationship between WFC and *** Doctors who had higher scores on work interfering with family confict, reported more emotional exhaustion （r=0.514, P〈0.001） and had a sense of accomplishment （r= 0.149, P〈0.001）. Simultaneously, family interfering with work （FIW） was positively associated with all dimensions of burn-out （r=0.2.3, 0.504, 0.088, respectively, P〈0.001）. Coping styles had partial, complete and even mediating effects on the relationship between WFC and burn-out among Chinese *** WFC was correlated with burn-out, and coping style was a mediator in this relationship among Chinese doctors. Coping style was a positive resource against burn-out.
