[结果 ]在 2 5个县中 ,发现全省有 6种淡水螺类可充当并殖吸虫第 1中间宿主 ,即放逸短沟蜷、湖北钉螺闽亚种、福建拟钉螺、建瓯洱海螺、小桥拟钉螺和新店拟钉螺 ,其感染率 ( % )分别为 0 2 6、0 5 3、0 15、0 49、0 15和 6 5 7;放逸短沟蜷分布较广。
In this article,based on the tool matlab,through computer programming,we realized the simulation of three-dimentional whelk model.
应用MATLAB软件编程实现了三维的模拟海螺模型。
This study takes "glacier-runoff" system of the Bingchuan River Basin of Hailuogou in Gongga Mountain region as research object,because this area has abundant information and data about glacier change.
分析多种数据和资料,再现海螺沟冰川过去100年来的冰川进退过程,分析发现,冰川末端变化阶段在滞后期的基础上,与北半球和中国气温变化的阶段相对应。
The formation,distribution,occurrence and harmful situation of the geologic hazards in Hailuogou Scenic Spot were discussed in this paper.
本文综述了海螺沟环境地质灾害的发育分布，活动与危害现状，作出了危害程度与危险程度综合评价、分区及灾情预测评估。
Hailuogou belongs to a branch gully on east slope of Mt.
贡嘎山海螺沟土壤环境背景复杂,土壤元素背影值中,Cu,Zn,Pb,Cr,Ni,Mn和F都高于全国土壤的背景水平,而元素Cd,As,Se则相反;各土类间同一元素含量的变化不大;成土母质对土壤元素含量的影响深刻;土壤元素含量的垂直分异规律不明显。
