Isolation and characterization of microsatellites in Chinese Soft-shelled Turtle,Pelodiscus Sinensis

, 2007
中华鳖（Pelodiscus sinensis(Wiegmann),1834）在我国分布很广泛，具有很高的营养价值和药用价值。在过去的10多年中，中华鳖野生群体资源受到了严重破坏，数量急剧下降。为了保护这一具有重要经济和科研价值的陆生野生动物，全国各地开展了大规模的人工养殖，然而人工养殖中华鳖的快速无序发展却导致了中华鳖的种质资源受到冲击。因此，中华鳖优良种质资源的准确、快速识别与保护成为当前中华鳖养殖中存在的主要问题。 目前，中华鳖不同品种的识别主要依靠其外部形态特征、经济性状特征 ...

超低轨道卫星气动特性分析与优化设计

超低地球轨道(VLEO)卫星在提升对地观测平台性能和降低观测成本方面具有显著优势.然而,在超低轨道环境下,大气分子与卫星表面碰撞所产生的气动阻力与气动热载荷给卫星的在轨运行寿命和安全带来了巨大挑战不可忽视.首先采用直接模拟蒙特卡洛(DSMC)方法,对100～300 km高度范围内超低轨卫星的气动阻力、气动力矩与气动热特性进行了分析,系统研究了轨道高度、表面适应系数和飞行迎角等条件对卫星气动力和气动热特性的影响规律.随后,基于平板外形与旋成体外形的减阻优化分析,提出了两种超低轨卫星减阻优化方案 ...
