Through the flux / retention experiments it was shown that when the applied pressure rises , both volume flux and rejection increase , too ; and that the higher the feed salt concentration , the lower rejection and volume flux . the charged mosaic membranes could permeate mono - valent and bi - valent inorganic salts , but reject the low - molecular - weight organics . furthermore , sem was used to observe the surface and the cross section of the composite membrane 另外，膜性能表征結果顯示:隨著操作壓力的增加，膜通量及膜對電解質的截留率均趨增加;而隨著原料液濃度的增加，通量和截留率都有所降低;膜對低分子有機物和無機電解質混合體系(如:亞硝基紅鹽與naci混合體系;蔗糖與nazso ;混合體系等)的選擇性較高，能實現其有效分離。
This paper introduced the remediation on contamination with chlorinated organics in water and soil by zero - valent iron on the latest research results at home and abroad , discussed the mechanism and research state of the zero - valent iron remediating contamination with chlorinated organics , and analyzed the development trend in the field 摘要介紹了零價鐵修復水土中含氯有機污染物的機理及目前國內外最新研究成果及現狀，并分析了該研究領域的發展方向。
In general , bu is used to negate non - verbs , zero - valent verbs and monovalent verbs , while though fu is often used to negate bivalent verbs and trivalent verbs , bu can also be used to negate these two verb types 一般說來，非動詞、零價動詞、一價動詞要用不來否定，而二價動詞、三價動詞常用弗來否定，但也可以用不來否定。
This paper proposed a convenient way for producing disulfides , along which disulfides can be readily prepared in moderate to good yields via the reduction of alkylthiocyanates by the low - valent titanium reagent in thf at 0 在四氫呋喃、 0反應條件下，低價鈦試劑能容易地還原硫氰酸酯生成相應的二硫化物，得到中等至良好的產率
