中文拼音 [húnyúnzhǎngdù]
混勻長度
英文
mixing length-
In order to avoid the limit of the uncertainty relation, we will compare the classical and quantum in the ensemble kinesis - levels. there is a time scale te. in thequantum ensemble distribute corresponding to the chaotic character of the ensemble distribute in classical phase space, if t > te, the quantum effect will restrict the increase of the degree of ensemble distribute irregularity
為了不受量子力學中不確定關系的限制，在系綜運動層次上對經典和量子動力學作比較，得到經典系綜相空間分佈的混沌特徵，在相應的量子系綜分佈的運動中存在一個時間尺度t _ e ，當t t _ e時，量子效應使得系綜分佈不均勻度得增長受到抑制。The next this text is based on the appearance theories, according to the characteristics that the temperature dispersion of super thick mass concrete planceer of high - rise building primarily is an even difference in temperature and an even constringency, suppose the level shears are line with the displacement, adopting a big physical volume concrete of planceer in flexibility foundation for plank computing model, from theoretically deducing the difference in temperature of mass concrete contracting should basic formula of dint, and analysis the crack rule and the influence factor of mass concrete temperature contract, and bringing up the theory calculation method about temperature stress of mass concrete and the biggest whole method that sprinkle the length, at the same time according to basic formula of the temperature stress of mass concrete and the concrete construction experience, bringing five technique measures to prevent the temperature crack of mass concrete
其次本文以唯象理論為基礎，根據高層建築超厚底板大體積混凝土承受的溫差主要是均勻溫差和均勻收縮的特點，闡述了大體積混凝土溫度應力理論計算的簡化方法和最大整澆長度的計算方法，同時根據大體積混凝土溫度收縮應力基本公式和大體積混凝土結構施工經驗，提出了防止大體積混凝土溫度裂縫的五項技術措施。最後本文以廈門郵電大廈3 . 5m超厚底板施工為實例，從大體積混凝土溫度應力計算、混凝土保溫材料厚度計算、混凝土配合比的確定，鋼筋工程、模板工程、混凝土的泵送和澆築以及大體積混凝土內部溫度的監測和後期養護等方面進行了理論應用。The vertical mixing law of the linear source in the natural river has been studied in the second step. at first the concentration equation of the linear source at different depth has derived. by the theoretical analysis, the relationship between the distance of the vertical homogeneous mixing and the part depth of homogeneous mixing, and the equation calculated distance of whole depth homogeneous mixing for the linear source have been presented
通過理論推導，得出任意位置上瞬時線源濃度場的解析解表達式；推導得到表面不同深度線源排放時垂向部分均勻混合水深隨縱向距離變化規律的函數關系，並建立了相應變化規律的諾莫圖；導出了表面不同深度線源在全水深均勻混合時的縱向距離的計算公式，應用長江口南通河段實測資料驗證，得到一致結果。
