stream erosion 中文意思是什麼
stream erosion
解釋
河道侵蝕-
What ' s more, we put forward some experienced formulas on the basis of the cortical analysis. the result of the research show that by installing diffluent piers with low ridge, we can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, also, we can improve the flow condition of down - stream. the fact that the main flow of down - stream is in the middle, not only effectively lower the speed of the bottom flow in the ridge rear, alleviate the erosion to the river bed, but also avoid the heavy wave resulted from the main flow in the surface, thus improve the surface wave of down - stream obviously. we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas, and then reckon the down - stream surface wave condition for the protected building of the down - stream bank
研究結果表明：設置低坎分流墩后，消除了擺動水躍水舌擺動的根源，提高了水躍的消能效果，改善了下游水流流態。下游水體的主流在中部，既有效的降低了坎后水流底流速，減輕水流對河床的沖刷，又避免了主流位於表面導致波浪過大的結果，下游的水面波浪明顯得到削減。依據經驗公式，可根據工程水流條件設計出低坎分流墩的體型參數，進而估算出下游沿程的水面波浪，為下游岸邊的砌護提供依據。 -

The good reservoir facies are braided stream and braided delta in alaer area, fan - delta in arhati area and lake - floor fan in shizigou - ganchaigou area. all of these areas are the main targets for oil exploration, it has discovered that there is an important unconformity between upper youshashan and lower youshashan formation of tertiary, on which there are a large amount of erosion and long time of depositional hiatues
在上述研究的基礎上，對區內油氣勘探的有利區帶進行了預測，指出阿拉爾北東辮狀河三角洲相帶、阿哈提南東扇三角洲相帶和獅子溝一乾柴溝湖底扇相帶為區內有利的儲集相帶，是今後勘探的主要目標。 -
3. bring forward a new idea : the ideology of synergetics used in atomic simulation and multi - scale simulation of materials design. on the basis of this, next tasks were put forward : ( 1 ) analyzing the changes of stress - strain curves of the interphase before and after pre - treatment ; ( 2 ) the efficient of the coupling effect of o2, na2s04 and h2o stream on the oxidation and erosion resistance of interphase ; ( 3 ) the methods of improving environment performance of interphase above 1273k
提出將協同學的思想用於原子級模擬及跨尺度模擬的思路，並在此基礎上，提出下一步的工作設想： （ 1 ）分析熱處理前後界面相區域應力-應變曲線的變化； （ 2 ）航空發動機模擬環境中，氧、硫酸鈉蒸汽及水蒸汽耦合效應對界面相抗氧化性、抗腐蝕性的影響； （ 3 ） 1273k以上界面相環境性能提高的方法。 -
