tonotaxis-
Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments. the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose, sucrose, malic acid, mannitol ), propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum, at a ph range of 4 to 8. 5, at a saline concentration range of 0. 01 % to 1. 5 % ; low nlv " concentration had little effect on its nitrogenase activity. ara could also be detected when it grow in the culture media with 5mmol / l ntv "
W12菌株對環境因子的適應性研究：無氮培養條件下，測定溫度、碳源、酸堿度、滲透壓對w12生長及固氮能力的影響，結果表明，在15 - 40下均能生長並表達固氮酶活性，其最適生長及固氮的溫度為25 - 35 ；能利用葡萄糖、蔗糖、蘋果酸、甘露醇等多種碳源生長並固氮，當培養基中同時存在蔗糖和蘋果酸時，細菌生長和固氮活性最強；在偏酸和偏堿的條件下（ ph4 . 5 - 8 . 5 ）均能保持較強的生長勢和較高的固氮酶活性，並能通過調節自身代謝平衡並適應環境的酸、堿性變化，使培養液趨于中性：能耐受較高的滲透壓，培養液中卜、 5 naci濃度對其生長和固氮酶活性影響不大，當naci濃度升至2時，菌株的生長勢及固氮酶活性才有所下降：低濃度的鉸對其固氮酶活性影響不大，在0The surface of natural fracture ( crack ) is parallel to the orientation of maximum principal stress. the principle orientation of anisotropic permeability reservoirs agrees with the orientation of the maximum principle stress. many engineering problems ( e. g. bore - hole stability, casing deformation failure during drilling, reasonable arrangement of wells, the optimum design of hydraulic fracture and so on ) are influenced by the in - situ stress orientation
天然裂縫面和裂隙面與最大主應力方向平行；在各向異性低滲透率油田中主滲透率方向與最大水平主應力方向趨向一致：在鉆井過程中井壁穩定性，套管變形和損壞，油田開發井網合理布置、水力壓裂優化設計等都與地應力方向有關。The self - weight of soil is an important factor affecting consolidation, and once it is taken into consideration, the consolidation becomes quicker and final settlement becomes larger. rheological property of soft soil contributes to delaying consolidation. the influences such as nonlinear variations of compressibility and permeability, rheological and layered properties of soil, self - weight and time - dependent loading are interacted each other and very complicated, and only they are all taken into consideration, can the consolidation behavior of soft soils be actually revealed
研究表明：大、小應變固結理論的差異隨土壓縮性或荷載的增大而越趨明顯；土體自重是影響固結的一個重要因素，考慮自重要比不考慮自重固結快、最終沉降大；土的流變性增大將最終遲滯軟土地基的固結；土的壓縮性和滲透性的非線性變化、土的流變性、成層性、自重及變荷載等因素對固結的影響相互交織，錯綜復雜，在固結分析中對之綜合加以考慮，才能真實反映軟土的固結性狀。
