水下发射超空泡射弹对UUV平台姿态影响分析     

魏平  侯健  鲁春佳  赵泽鹏  荣里 《数字海洋与水下攻防》2020,3(3):230-235

超空泡射弹武器能够突破普通射弹水中运动极限，有效打击水雷等水下目标。针对水下发射超空泡射弹武器的平台适应性开展了初步研究，建立了超空泡射弹武器及 UUV 搭载平台仿真模型，计算分析了水下超空泡射弹武器在不同方位、不同角度发射时 UUV 平台姿态角的变化，得到了水下发射超空泡射弹对 UUV 平台姿态的影响规律，为水下超空泡射弹武器系统及其平台适配性研究提供了依据。  相似文献   

ECOLOGICAL SERIES OF SOIL ANIMALS IN DARLIDAI MOUNTAIN   总被引：1，自引：0，他引：1  

HOUWei-ling FANHong 《中国地理科学(英文版)》2002,12(4):378-382

The ecological series of soil animals under the broad-leaved and pine mixed forest in Darlidai Mountainwas studied. Seven sample plots were selected according to different altitude gradients, which belong to different vegeta-tion types. By investigating and analyzing soil animals in every sample plot it is found that there are 45 groups and 1956individuals, which axe involved in 3 phylums, 7 classes, 16 orders, respectively. The altitude is a key factor which af-fects ecological series of soil animals. Both the groups and individuals of soil animals increase with altitude increasingunder certain conditions, which contrastes with ordinary cases, resulting from special micro-climate in studied area. Thegroups and individuls of soil animals are the most under the broad-leaved and pine forest on the top of the mountain, andthe least under Picea-Abies forest in the foot of the mountain.  相似文献

ELECTROCHEMICAL CORROSION BEHAVIOR OF STEEL IN THE JUNCTURE AREA OF SEA CLAY AND SAND     

张经磊  侯保荣  郭公玉  杨芳英  谢肖勃 《中国海洋湖沼学报》1993,11(2):171-175

Corrosion behavior of steel in the juncture area of sea clay and sand was studied. The results show that galvanic corrosion occurred between steel samples buried in sea clay and sand, and that the polarity of the galvanic cell reversed after some testing later. The cause of reversing of polarity is discussed.  相似文献
