Abstract : hill mourning the special and advantageous natural conditions , ailaoshan become enormous natural biological species of germplasm resources gene pool , yunnan as " animals and plants " kingdom of " natural museum " and " specimen garden , " is a variety of integrated science experiments , is the ideal many disciplines scientific investigation and research base , is the scientific expedition , adventure , photography , research and returned to the natural forest of choice for this paper , through the ailaoshan reptilia from the investigation , ailaoshan the right reptilia is a more systematic and well described 摘要：哀劳山特殊而优越的自然条件，使哀牢山成为巨大的天然生物种的种质资源的基因库，成为云南"动、植物"王国中的"天然博物馆"和"标本园" ，是多种自然科学的综合实验地，是众多学科的理想的科学考察和研究基地，是开展科考、探险、摄影、科研、回归自然、森林的首选之地，本文通过对哀牢山爬行纲的抽取调查，对哀牢山的爬行纲给出一个较系统的，完善的叙述。
This paper is based on the ocean science exploring ship of ocean 1 . beyond the work of analysis of ordinary dynamic positioning ( dp ) fuzzy controller , research on auto area keeping when inputs contain errors that ca n ' t be neglected , energy as index function , is probed into 本文以“大洋一号”海洋科学考察船为对象，在研究了“大洋一号”的普通动力定位模糊控制系统的基础上，以能量为评估函数，对输入中包含误差情况下的自动区域保持控制方法进行了有益的探讨。
Legged robot has the high adaptability to the environment , it can be applied in the fields of scientific investigation , national defense , aerospace exploration etc , in recent years , research on biped humanoid robots and quadruped robots was most exciting topics in the field of robotics . while researchers work completely on the dynamical biped walking and the quadruped walking , there is less study on the dynamical quadruped walking ? especially on irregular terrain 由于腿式机器人对环境有较强的适应性,可应用于科学考察、国防、空间探索等诸多领域,近些年来,仿人双足步行机器人和仿生四足步行机器人一直是机器人领域非常热门的研究对象。虽然研究者们对两足机器人的动步行和四足机器人的静步行都有了非常深入的研究,但对四足机器人的动步行?特别是野外和不平坦路面等复杂地况下的动步行研究还很少。
Based on the quantitative studies of siliceous microorganisms and terrestrial detritus in 12 surface sediment samples , which were recovered by the first chinese national arctic expedition team , in the bering sea , it goes without saying that diatom abundance is dominant within the microorganisms which consists of diatoms , radiolarians and sponge spicules 摘要中国首次北极科学考察在白令海?取了12个表层沉积物样品，其中对矽质生物和陆源碎屑的详细研究发现，它们主要由矽藻、放射虫和海绵骨针组成。
