1) lack of earthquake section
缺震段
2) earthquake deficiency
缺震
1.
The characteristic of seismicity anomalies before medium earthquakes is studied with the parameters that reflect frequency,energy,mean magnitude,such as frequency,earthquake deficiency,total area of fault plane and degree of seismicity.
近年来首都圈地区以中等地震活动为主,本文用反映地震频度、能量、平均震级的基本参量如频度、缺震、断层总面积、地震活动度等研究该区中等地震前的活动性异常特征,发现这些异常对1999～2001年首都圈地区的中等地震有较好的对应关系,当同时出现三项低值异常后,有震预报准确率较高。
3) Anomaly of seismicity gap
缺震异常
4) eastern part of Northwest China region
地震空缺
1.
In this paper, through study on earthquake distribution features and evolutional process of about 10 strong earthquakes occurred with different times scales in the eastern part of Northwest China region since 1900, we have found that there have existed the following law before strong earthquake in the region, i.
通过对 1 90 0年以来西北地区东部 1 0次强震前不同时间尺度的地震分布特征以及演化过程的研究表明 ,西北地区东部强震前大多存在以下规律 :即在震中附近存在 5级以上地震空缺的长期异常特征及中小地震活动水平升高的中短期异常特
5) anoxic phase
缺氧段
1.
A study on the anoxic phase of the A/O hybrid biofilm process was carried out intensively.
对A/O复合式生物膜工艺的缺氧段进行了深入研究,并以物料平衡理论为基础,结合莫诺方程和Fick定律,建立了相应的底物降解和微生物增殖的动力学模型。
