  1. Excessive mesial - axial inclination of the mandibular second molar or inadequate posterior arch length cause the mandibular second molar to become impacted against the distal contour of the first permanent molar

    摘要下顎牙弓空間不足或第二大臼齒本身過度的近心軸向傾斜,常造成第二大臼齒前傾和阻生。
  2. The calculation method of ln ( / tan # ) index widely used is the multiple flow direction algorithm developed by quinn et al. it can been seen that, in the algorithm, the contour length normal to the direction of flow flowing out the current cell is used to determine both a and tan #, and that the calculated total cumulative contributing area of downslide grid cell does not include the area of the current cell

    目前普遍使用的計算該地形指數的方法為多流向法。方法中計算和tan用的均是與流出單元網格流向垂直的等高線長。另外計算下坡單元網格累積匯流面積時沒有考慮欲計算ln ( tan )值的單元網格的面積,這些是不合理的。
  3. Topmodel is based on the calculation of ln ( / tan # ) index and its distribution. in terms of a dem, a is the cumulative upslope area draining through per contour length to a pixel, which reflects the tendency of water to accumulate at any point in the catchment, tan # is the local slope angle of the cell, which reflects the tendency for gravitational forces to move that water downslide

    Topmodel是以計算ln ( tan )指數及其分佈為基礎的。對于柵格dem ,為上坡區域通過單位等高線長匯集到單元網格內的面積,反映徑流在流域中任一點的累積趨勢, tan為單元網格的坡度,反映重力使徑流順坡移動的趨勢。
  4. It is found that the contour length used to determine a should be that normal to the directi on of flow entering into the current cell, rather than that flow out the current cell

    計算值應該用與流入單元網格流向垂直的等高線長,據此提出了改進后的ln ( tan )的計算公式。
  5. For the image with random field feature, the description language is probability distribution model, and the description length equals the negative base - two logarithm of the probability of the image data ; for the region homogeneity properties of active contour, the description language is chosen as a sign gradient map, and the description length is the summation of sign gradient inside the active contour ; for the active contour regularity, the description language is smoothness, and the corresponding description length is the length of active contour curve

    隨機場圖像的描述語言採用概率分佈模型,描述長度是圍道內外區域中圖像數據概率的以2為底對數的負數;活動圍道區域一致性的描述語言為有符號的梯度圖,描述長度是圍道內區域有符號梯度的總和;圍道形態的描述語言採用平滑性,描述長度正比于圍道的長度。
  6. The paper analyzed the struture of the tri - eccentric butterfly vavle at length, defined the tri - eccentric butterfly valve, educed the geometry function and its characteristic about the section of the butterfly disc. the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse, thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body, combining the torque, we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle

    本文主要分析了三偏心蝶閥的結構,給出了三偏心的定義,推導出了蝶板截面的幾何方程及其性質,結果表明,沿蝶板厚度的平行截面輪廓線為標準的橢圓形,進而推導出了蝶板幾個主要截面的幾何參數(長軸、短軸)與三個偏心之間的函數關系;考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉,結合蝶板的啟閉扭矩,確立了三偏心蝶閥回轉中心的適宜區域。
  7. Through carrying out analysis on the aesthetics shape elements of 37 kinds of sample book, 12 shape elements for describing the contour features of industrial sewing machine, such as the elements of ratio between fuselage length and fuselage height and of shape of central part main shaft section etc. were defined

    通過對37種樣本的美學形態要素進行分析,定義了描述工業縫紉機外形特徵的12個形態要素,如機身長與機身高比率、中部主軸截面等形態要素。
