Abstract : through the studies on three kinds of examples of chinese successful predictions since the haicheng earthquake , and based on analysis of the complication of precursory phenomena , this paper puts forward that prediction ideas of “ the dominant factors and the subsidiary factors ” for medium term - short impending earthquake predictions can be adopted at present , that is the prediction ways of relying mainly on seismicity while making abnormal precursory phenomena subsidiary 文摘:通過海城地震以來我國地震預報成功的三種類型實例的研究和基于前兆現象復雜性的分析,提出了現階段中期短臨預報可采用“一主二輔”的預報思路,即以地震活動為主,前兆異常現象為輔的預報途徑。

Due to the influence of climate drought and human activities , the ecological environment of qinghai province is in an increasingly grave condition , namely , climate abnormal events occurring frequently , grassland degenerating , ground sanding , glacier shrinking , water level of lakes descending and river runoff decreasing , and so on . in the basis of extensively collecting and analyzing the data of qinghai ecological environmental factors such as climate , water resource and grassland resource etc . , the further basic research is performed on the ecological environment characters of main climate factors , surface runoff , water resource , lcc and their correlation to coordinate with the basic , strategic and precursory research for the development of china west part and provide the scientific foundation for corresponding development both ecological environment and social economy , and persistent utilization of natural environment resource 本研究針對當前在氣候干旱化和人類活動的共同影響下青海省生態環境中氣候異常事件即氣象災害頻繁發生、草場退化、土地沙化、冰川萎縮、湖泊水位下降和河流流量減少等生態環境退化現象日益嚴重的實際,在廣泛收集和整理青海省氣候、水資源、草地資源等生態環境因子基礎資料的基礎上,對青海的主要氣候要素、地表徑流、水資源、植被的演替及其相互間的關系等主要生態環境變化特征進行了基礎性的研究。

I recognize this as an element of davis ' s “ experiment ” to see whether , given the right conditions and enough time , the components of machines can self - assemble into working devices , just as life supposedly arose spontaneously from colliding precursory biochemicals billions of years ago 我認出這是戴維斯的實驗,他想知道一堆機器零件要是條件適當,時間足夠,是不是會自動組裝成能夠運作的玩意兒,就好像我們認為幾十億年前生化物質的前驅物互相碰撞,然后生命就自然發生了。

Through the studies on three kinds of examples of chinese successful predictions since the haicheng earthquake , and based on analysis of the complication of precursory phenomena , this paper puts forward that prediction ideas of “ the dominant factors and the subsidiary factors ” for medium term - short impending earthquake predictions can be adopted at present , that is the prediction ways of relying mainly on seismicity while making abnormal precursory phenomena subsidiary 通過海城地震以來我國地震預報成功的三種類型實例的研究和基于前兆現象復雜性的分析,提出了現階段中期短臨預報可采用“一主二輔”的預報思路,即以地震活動為主,前兆異常現象為輔的預報途徑。

The current moderately strong earthquakes in east china have been preliminarily classified according to the tectonics based on information from laboratory study results - it presents the similar fracture pattern and characteristics of precursory evolution to similar structural tectonics on the action of extra adding loads 摘要基于在相似外載荷作用下結構相似的構造可表現出類似的破裂圖像及前兆演化特徵的實驗室研究結果,對華東地區現代中強地震進行了初步構造分類,在此基礎上分析研究了19次震例前地震活動圖像異常的統計特徵。

The results show that in the later stage of the nucleation process , the maximum slip velocity is monotonically accelerating ; the slipping hot spot ( where the slip rate is maximum ) migrates spontaneously from a certain instant , and such migration is spatially continuous ; when the maximum velocity reaches a detectable order of magnitude ( at least one order of magnitude greater than the loading rate ) , the remaining time is 20 hours or more , and the temporal variation of slip velocity beyond this point may be used as a precursory indicator ; the average slip velocity is related to the remaining time by a log - log linear relation , which means that a similar relation between rate of microseismicity and remaining time may also exist ; when normal stress variation is taken into account , time scale of such processes can be extended by about 2 times 結果表明,在成核的后期階段:最大位移速率單調加速增加;滑動熱點(最大滑動速率處)在后期階段開始自發性遷移,且在空間上連續;當最大滑動速率達到可以明顯探測的量級時(高于載入速率一個數量級以上) ,倒計時間為20小時或更長一些,這時的速率變化可作為臨震預測標志;平均滑動速率與倒計時間的關系在臨震階段呈對數線性趨勢,由此可推測微震活動增長率與倒計時間同樣存在對數線性關系;正應力的變化對上述時間尺度有延長作用,使之大致增加到原數值的2倍。
