Heavy precipitation often forms in the place between the source of high - disturbance wind field at 200hpa, especially of low - disturbance wind field at 850hpa. ( 2 ) the temporal and spatial scale about e - reflection index of nonlinear subcritical symmetric instability disturbance is 5 - 8hours and 200 - 300km respectively
非線性亞臨界對稱不穩定使線性對稱穩定的大氣變為不穩定。降水區和暴雨中心主要位於高層200hpa和中層500hpa擾動風場極大值南側與低層850hpa擾動風場極大值北側之間。 -
Applying the energy equation and boundary layer theory, this article also analyzed the relationship of energy transformation of overflow, and obtained the experience index and formula of instability critical conditions
並應用水流能量方程和邊界層理淪，研究了圍堰過水時的水流能量轉換關系，得到了穩臨界條件的指標和經驗判別式。 -
At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face, and studies the stress, strain, stability ' s condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face. geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten. based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors, and discusses other factors that influence the bedding rock slope ' s stability, so gains the evaluating and forecasting index marks
本文首先對順層邊坡的層狀巖體及其中的層理面和不連續面進行了分析，對其應力應變進行了研究，得出了順層邊坡的穩定性不僅與巖體中巖石的強度有關，還與巖體中層理面及不連續面的內聚力、內摩擦角及其傾角有關；論文建立了層理面和節理面的地質力學模型，討論了其力學參數變化對邊坡穩定性的影響，並在此基礎上將層理面和節理面歸納為順層邊坡穩定性的結構面影響因素，同時討論了影響順層邊坡穩定性的其他因素，從而得出順層邊坡穩定性的評價預測指標。
