对我国新疆地区的疟疾媒介米赛按蚊(Anopheles messeae Fall,1926)进行了唾腺多线染色体的研究,报道了多线染色体的核型照片和模式图。本研究还发现,米赛按蚊存在着4类种内多态性臂内倒位:①2R的杂合子倒位,②3R的杂合子倒位,③3L的杂合子倒位,④3L的纯合子倒位,并统计了倒位频率。新疆地区与苏联境内的米赛按蚊比较,多线染色体带型未见明显差异;多态性倒位类型相符,但频率不一致。

Based on observations of air temperature in the atmospneric boundary lay- er and measurments of wind speeds with pilot balloon from 1987 to 1988, and ground meteorological observation for many years in Fushan City, we analyze the meteoroliogcal conditions in the atmospheric boundary layer in four seasons. Result shows that ground wind in winter is mainly tendency to north wind, and southeast wind in summer. The thickness of mixed layer reaches its maximum in summer, while minimum in spring.
