    葉的上下表皮厚度、 1和2年生枝木質部及韌皮部寬度、晚材早材比值、 2年生枝的周皮厚度、木射線長等均隨緯度升高而呈下降趨勢；而葉的柵欄組織和海綿組織比值、 1年生枝表皮厚度、 2年生皮層厚度等解剖結構隨緯度變化沒有明顯規律。
  2. The notable torsion effects of the surface ground motion above the alluvial valley are illustrated and the torsion effects become stronger as the frequency of the incidence is higher. ( 4 ) antiplane surface motion of the underground circular soft inclusion and the underground homogeneous soft interlayer is investigated in this paper. the results indicate : surface displacement amplitudes just above the soft inclusion of small depth - to - width ratio is amplified and soft interlayer of small depth - to - thickness ratio is amplified to a certain degree, and moreover, the latter is lower limit of the former

    結果表明：垂直入射時，小深寬比軟夾塞上方地表位移幅值有較大的放大，小深厚比軟夾層的地表位移幅值也有一定的放大，且後者為前者的下限；波接近掠入射時，軟夾塞正上方地表點和軟夾層的中國地震局工程力學研究所碩士學位論文一地表位移幅值都沒有放大，而軟夾塞迎波面一側地表點的位移幅值會有一定的放大；軟夾塞上方的地表位移運動有較強烈的扭轉效應，且此扭轉效應隨入射波頻率的增高而增強。
  3. It is also found from the tests that the ultimate capacity of connection is greatly affected by the ratio of the width of branch to that of chord, the thickness of chord and the angle between chord and branch

    試驗結果顯示，節點的承載能力與腹桿和弦桿的寬度比、弦桿的壁厚、腹桿和弦桿夾角密切相關。
  4. In the plate region of a vehicle image, the gray value varies frequently in cross - direction, so we define a parameter ". cross variance " to describe it. we also calculate other parameters to approximately locate the plate, they are the space length between two chars, the thickness of stroke, the peak and trough of gray value, the ratio of width and length, etc. at last, we exactly locate the plate by the theory of mathematical morphology

    該方法根據圖像車牌區域橫向灰度值變化頻率比較大這一特徵提出了橫向方差參數，並結合車牌的字元間距、筆劃粗細、灰度峰谷值、長寬比值等特徵粗定位車牌，在車牌的精確定位中利用了數學形態學的方法。我們從某高速公路收費站實地拍攝的照片中選取了1000多幅作為實驗樣本數據。
  5. Since the plate is relatively wider and the width - thickness ratio of plate is always larger, the section of cold - formed steel is easy to buckle

    由於冷彎型鋼截面開展，各組成板件的寬厚比往往較大，截面容易凸曲。
  6. Fifty concrete filled thin - walled steel tubular stub columns were axially tested, where diameter ( width ) to thickness ratio was selected as the main varied parameter. the behaviour of concrete filled thin - walled steel tubular stub column was analyzed, and the simplified calculation method of bearing capacity was discussed. based on the current test results and those reported in the literature, the upper limits of d / t and b / t of cfst members were recommended

    以截面徑（寬）厚比為基本參數，進行了50個薄壁鋼管混凝土軸壓力學性能的實驗研究，考察了薄壁鋼管混凝土的軸壓力學性能，並對其軸壓強度的計算方法進行了探討，基於本文和其他研究者的實驗結果，建議了鋼管混凝土構件截面合理的徑（寬）厚比限值。
  7. In these paper we use the following rule to determine the width - to - thickness ratio : if the local buckling has visible effect on the overall buckling capacity, then this width - to thickness ratio should not be exceeded based on the resul ts obtained, we proposed a new formula for the limitation of the ratio of h / tw of the t - section columns " webs

    根據局部失穩對整體失穩不應該有顯著影響的原則，最後得到t形截面壓桿腹板的寬厚比限值計算公式。本文對規范修訂和工程應用有一定的參考作用。
