中文拼音 [bìhòujiǎnbó]
壁厚減薄
英文
wall thickness reduction-
These are formed from a zone containing larger vessel elements produced by the cambium in the spring ( lighter layer ), followed by a zone containing smaller vessel elements ( darker layer ) produced during the late summer
春季，形成層活動旺盛，形成的次生木質部細胞，管徑大而壁厚，色澤較淡；夏末，形成層活動逐漸減弱，形成的次生木質部細胞，管徑小而壁薄，色澤較深。Corrosion and pitting defects in pipe work are major problems in the oil, chemical, and other industries
管道的腐蝕、壁厚減薄等缺陷是石油、化工和水暖工業中面臨的主要問題。These defects can occur at the outer or inner surface of the pipe and can lead to a serious loss of pipe wall thickness
這些缺陷既可能發生在管道外壁又可能發生在管道內壁，通常致使管道壁厚減薄。X - ray diffraction results revealed that the structure of as - deposited smco film was amorphous and crystallization happened after the films annealed at 500 in vacuum. the magnetic tests of smco thin films showed that its coercivity reduced with the increase of film ' s thickness while the ratio of mr / ms was opposite. the films " coercivity and mr / ms declined after it annealed at 500 because the machanism of magnetization were changed from domain wall nailing into magnetic nuclear forming
研究結果表明，由於雜質fe的摻入降低了smco薄膜的磁性能；制備態smco薄膜為非晶態結構，矯頑力hc隨著薄膜厚度的增加而減小，剩磁比mr ms隨膜厚增加而增加；經過500真空退火熱處理后，薄膜出現smcos的結晶物，矯頑力hc降低， mr ms減小，磁化機制由疇壁釘扎類模型轉為形核類模型。Its reliability has been tested though examining. the influence laws of mould structure, including wiper die and the style, size and installed position of mandrel, have been studied. combined with the theoretical analysis of perfect pure bending, the tendency of relative bending radius r / d and relative wall thickness t / d to one of the major quality target - the maximum wall thickness reduction ratio is also studied
通過數值模擬研究獲得了包括防皺塊和芯棒形式、尺寸和安裝位置在內的模具結構對製件成形質量的影響規律；結合對理想純彎曲的理論分析，研究獲得了相對彎曲半徑r / d 、相對壁厚t / d對製件主要質量指標之一的最大壁厚減薄率的影響趨勢和大小。Thus it is necessary to find out an reasonable approach for design of drum ' s wall based on scientific theory and experiment
為此，有必要研究並尋求一種更加科學合理又能減薄捲筒壁厚的設計理論和方法。On the basis of detailed comparison and analysis, the paper proposed ways of using the k2 bogie and hdsa light - duty solid wheel, getting through the partition wall, canceling the longitudinal sill of the roof and decreasing the thickness of the board where the value of stress is low, using high intensity steel, increasing section dimensions of center sill and side sill, to improve the whole carrying capacity
本文在比較分析的基礎上，提出了裝轉k2轉向架，採用hdsa輕型碾鋼輪，打通隔墻，取消車頂縱向梁，在應力小的部位減薄壁厚的減重對策；採用高強度耐候鋼，加大中梁、側梁的截面尺寸等措施，提高車輛的承載能力。Trough choosing different professing parameters including the ratio of thinning and the ratio of feeding and using two rollers power spinning machine experiment research on cylinders with inner ribs has been started
摘要通過選取不同的壁厚減薄率和旋輪進給比作為工藝參數，利用雙旋輪強力旋壓機對帶內筋筒形件作旋壓加工實驗。分享友人
