quasi-continuous variation

The seasonal variation of the global tropopause zonal mean ozone mass mixing ratio anomalies has obvious quasi-semiyearly variation, and has opposite connection between Northern Hemisphere and Southern Hemisphere.

对流层顶臭氧质量比纬向距平的季节变率表现出准半年变化趋势，且两半球变化趋势相反。

The results show: there are the quasi-periodic features and unsuccessive jump phenomena in the interannual variation processes of Northern Hemisphere monthly mean general circulation anomalies.

结果表明：北半球月平均环流异常年际演变的过程具有准周期特征及不连续的跃变现象。

The study concludes that the municipal water has basic natures of coupling, integration, level variation and dynamic, and economic and technical characteristics of regional monopoly, quasi-public goods, externalities, capital-intensive investment and a long period of return.

研究认为城市水务产业具有耦合性、整体性、层次性和动态性的基本属性；具有区域垄断性、准公共物品性、外部性、资本密集和投资回收期长等技术经济特征。

Abstract This paper proposes a quasi 3 dimensional simulation method of the condenser, which can take the 3 dimensional influence caused by the variation of the cooling water temperature, and also reflect the influence of the cooling water technological process arrangement to condenser's performance.

提出了一种凝汽器的准三维模拟方法，它可以考虑冷却水温度变化产生的三维影响，也能反映冷却水流程布置对冷凝器性能的影响。
