high rate aeration
解釋
高速曝氣-
The carbofuran - degrading experiment of cds - 1 was carried out in lab scale, the results showed that the highest degrading efficiency was obtained with ph, temperature being 7. 0, 30c respectively ; the change of aeration had no influece on degrading rate ; the increasing inocula could accelerate carbofuran degrading progress ; the degrading capability of cds - 1 was n ' t inhibited by high carbofuran concentration ; the addition of low concentration of nutrients had no distinct effect on the degrading rate while high concentration had inhibiting effect the distribution of degrading enzyme was also primarily studied, the results showed that degrading - related enzyme was endocellular and degrading progress was not cometabolism
Cds - 1的降解酶（系）是誘導酶（系） ，存在明顯的誘導期；胞內、胞外酶實驗表明呋喃丹降解酶（系）存在於細胞內。添加低濃度外源營養物質對cds - 1的降解性能無明顯影響，說明cds - 1降解呋喃丹的過程不屬于共代謝過程，可以在無外源營養物質存在的條件下降解呋喃丹。添加高濃度外源營養物質會對該菌降解性能產生抑制。 -
Space saving, high ammonia and nitrogen elimination rate, cost saving. function waste liquid is inducted via aeration pipe or pump
目篩網轉輪，逆過濾並轉動篩網旋轉，濾下固體物，經快沉裝置，行固液分離。 -
It was estimated that the yield of the e2 fusion protein in culture supernatant of recombinant p. pastoris could be reached 0. 34g / l. the optimal expression conditions were explored for the ph, aeration rate, final concentration of methanol and kinds of growth media. we conclude that the higher quantity of e2 protein can be gained at ph4. 0 - 6. 0, 1 % methanol as the final concentration, mm growth media and high aeration rate
通過對表達條件如ph值、通氣量、誘導甲醇終濃度、培養基的選擇等條件的探索，可確定豬瘟病毒hl - ly株e2基因表達的理想條件為：最適ph值在4 . 0 6 . 0之間，最適培養基為mm培養基，最佳誘導的甲醇終濃度為1 ，加大通氣量時表達量較好。 -
The surface material is liable to erosion wear with high - velocity sediment - laden flow, hi this paper, sand wear mechanisms are discussed and some effects of significant flow factors on material wear are analyzed ; the possibility of preventing erosion wear with aeration is proposed ; based on test data, the formula for calculating the concrete material wall surface wear rate is derived. it is indicated that the wear rate is related to the air concentration, the strength of material, the flow velocity and the sediment content. it is shown that wear rate can be reduced with the help of flow aeration
分析了空蝕與磨蝕的不同物理特徵；探討了沙粒磨蝕機理，提出了影響磨蝕vi河海大學博士學位論文一的因素；研究了摻氣抗磨的可能性：建立了混凝土材料壁面磨蝕率的計算公式；說明含沙水流對固壁材料的磨蝕率隨摻氣濃度、材料強度的增大而減小，隨水流流速、含沙量的提高而增大；利用摻氣可有效地降低過流表面的泥沙磨蝕率。
