Literature Research The etiological factors of POF are not still clear. The changes of sites and numbers in X chromatosome, X; autosome translocations, a forkhead transcription factor gene (FOXL2) mutations, FRAXA premutations and inhibits gene mutations are found in POF patients, so genetic disorders have been thought to be involved. Irradiation, chemotherapy or pelvic operations can damage ovaries and cause ovarian atrophy and failure, so it is thought one factor of POF.

一、文献研究 POF的确切病因目前尚不清楚，从POF患者体内检测到X染色体上位点和数目的变化，X染色体与常染色体间的平衡易位，脆性X基因前突变，FOXL2基因突变，抑制素基因突变等，故认为POF发生与遗传因素有关；由于放射、化疗或盆腔手术等可损伤卵巢，导致卵巢萎缩，出现卵巢衰竭，故也是导致POF的因素之一。

The instructive conclusion was: 1 under the vertical loading, the shear-lag effect was produced badly, more severer under concentrated loading than under uniform loading .2 the longitudinal bending deformation of the beam flange was true of the imitating plane assumption of deformation . 3 the width length ratio was confirmed as the first factor working on the shear-lag effect among all the geometric parameters;4 the shear-lag coefficient of simple-supported box-girder was severer than the continuous box-girder, the shear-lag effect in the inner supported section of continuous beam was much more severer, we need paying more attention for it in designing. 5 the non-liner characteristics of material deformation have littlie influence on shear-lag effect in BGCW. 6 the experiential calculating formulation and calculating diagram for the effective flange width was raised with the only factor of the width-span ratio., but the primary location of axis of bending moments should not be changed while calculating the inertial moment .

研究认为：1室内模型试验和空间有限元分析结果均表明波形钢腹板组合箱梁在竖向荷载作用下，翼板出现了典型的纵向应力剪滞效应。2在竖向荷载作用下，截面高度上各点纵向正应变分布认为可符合"拟平截面假定"，以此作为波形钢腹板组合箱梁抗弯计算的基本假定。3箱梁宽跨比是影响波形钢腹板组合箱梁翼板剪滞效应的主要因素。4连续波形钢腹板组合箱梁的翼板剪滞系数大于简支梁，且连续箱梁内支点截面翼板剪滞效应相当严重，对此需十分重视。5当混凝土翼板受力由弹性阶段进入弹塑性阶段时，材料的非线性特性对翼板的剪滞效应影响甚微。6提出了根据组合箱梁的宽跨比参数来计算翼板有效宽度比的经验公式和计算图表，但箱梁截面抗弯惯性矩的计算不应改变原先的截面中和轴位置。
