Based on the analysis of satellite images of various periods, landform data and river channel transverse section evolution in the lower yellow river, the characteristics of the river channel boundary condition changes at different location are clarified as middle flood channel flood transport width and area are evidently decreased especially for the main channel with comparison to 1950s, beach area that is unimpeded before become blocked because of road, irrigation channel constructed on it, and consequently intensify high edge of beach and lowering dyke and river
在現場查勘的基礎上，通過對丹江口水庫和小浪底水庫攔沙初期下遊河道演變、排洪能力變化特點的對比，分析了黃河下游防洪面臨的新形勢:小浪底水庫攔沙初期，下遊河道發生沖刷，但艾山以下窄河段沖淤變化不大，近年來形成的淤積萎縮的狀況難以很快改觀，游蕩性河段調整劇烈，工程出險機遇增大，河道水位流量關系中水流量以下部分同流量水位明顯降低，中水流量以上部分水位降低幅度可能會明顯偏小，防洪形勢仍不容樂觀。Conclusions the procyclic stenosis, such as the postcyclic abnormal structure, is frequently detected in vertebrobasilar ischemia
結論后循環血管結構異常是最常見的導致椎基底動脈缺血的血管性病因，前循環狹窄亦是致病因素之一。We find that the relations between the electronic effective mass of lowest - lying conduction band and wave vector are resemble, not only for narrow - gap semiconductor zigzag tubes but also for wide - gap semiconductor zigzag tubes. the electronic effective masses at bottom of lowest - lying conduction band depend on their tube - diameters
我們發現，無論是鋸齒型窄隙半導體管還是鋸齒型寬隙半導體管，同一類管的最低導帶的電子有效質量隨波矢變化的規律基本相同，且其導帶底的電子有效質量隨管徑的增大而減小。
