不稳定分布 meaning in English
unstable distribution
Examples
- Potential instability existed near 0 in the warm area and between - 10 and 0 in the cold area . the occurrence of potential instability was corresponding with maximum rainfall and maximum vapor content
C附近，冷区位势不稳定分布在一10一ooc ，位势不稳定出现的时间与地面强降水、水汽最大累积区出现的时间一致。 - It was well known that the main process of precipitation formation was collecting cloud water in the warm area and ice phase particles melting in the cold area . positive vertical velocity existed between 700hpa and 500hpa in the warm area and near surface in the cold area . wind convergence existed at the height of 700hpa , and divergence existed above and below the height of 700hpa
通过对降水云系的综合研究，建立了河南省春季层状云降水概念模型：暖区降水主要通过云水碰并形成，冷区降水机制以冰粒子融化等冷云过程为主;暖区700一50ohpa通常有上升气流，冷区上升气流分布在近地面附近: 700冲a存在风场的辐合，其上下则主要是辐散区;水汽主要集中在7o0hpa高度上，暖区水汽来自南、东南方向，冷区水汽以西南输送为主;暖区位势不稳定分布在o 。 - The field study indicated that most of the species and their densities in this area were unstable in different seasons and different years ; 60 % of the species were getting reduced ; few species , such as emberiza cioides , were almost stable and few species , such as cyanopica cyans , were getting increased
近10年来调查资料显示，该区鸟类的物种数及多数种类的数量在不同季节和不同年份呈不稳定分布：约60 %的鸟类的数量趋于减少；少数种类基本稳定（三道眉草?等）或呈增长趋势（灰喜鹊等） 。
