Four microsatellites IDG VA-11, IDG VA-27, IDG VA-44 and IDG VA-46 were used to analyzegenetic diversity of five cattle breeds. The average gene diversity of the four loci was 0. 57, of which IDG VA-11 was 0.66. Genetic diversity of five cattle breeds was 0.57, Nanyang was the highest 0.66, Yanbian andKorea cattle were 0.51 and 0.53, respectively. The fact that the observed diversity was lower than expected inSimmental and Piemontese crossbred showed existing selection and inbreeding impacts. The gene flow betweenYanbian and Korea cattle, and that between Simmental and Piemontese crossbred were as high as 23.79 and7.15 for each pairs of them, which showed their closer origins.

目的对某常规潜艇连续潜航8 d过程中舱室的PM2.5、PM10和总悬浮颗粒物(TSP)污染现状进行调查分析。方法采用TSI8533气溶胶检测仪，对某常规潜艇进行随艇检测。航行中每天检测1个舱室；每分钟采样1次，取24 h平均值，单以系泊时检测数据作为对照。检测数据采用Excel 2010分析处理。结果检测艇正常潜航状态下，除厨房外其余舱室的气溶胶浓度均较低，并未超出国家相关标准，厨房PM2.5浓度
