Dear Editor,Previously,the Mendelian phe no types in huma n oocyte maturation arrest,fertilization failure and early embryonic arrest,are largely *** recent years,"missing"Men delian phe no types and genes in these processes are beginning to be uncovered by us and others(Huang et al.,2014;Alazami et al..2015;Feng et al.,2016;Xu et al.,2016;chen et al.,2017;Sang et al.,2019).However,the genetic basis for majority of patients resulting from abnormalities in these phe no types remains to be elucidated.

采用条干不匀纱线的B样条曲面造型技术,模拟平纹织物由于纱线不匀所形成的外观效果。首先,利用USTER ME 100测试玻璃纤维长丝纱线的条干均匀度,并将相关数据转化为符合纱线B样条曲面造型技术要求的参数,代入纱线模拟数学模型,完成对玻纤长丝纱的三维模拟;其次,根据Peirce机织物结构模型计算其几何结构,作为纱线关键控制点设置的依据;最后,对每根经向纱线的起始点进行随机设置得到其控制曲面,对纬纱第一根纱线起始点进行随机设置,对后面所有纬纱的起始点位置则根据织物幅宽依次进行设置。当所有的纱线模拟完成后,玻纤长丝纱均匀度对织物外观的影响程度在计算机屏幕上自动显示,从而预测玻纤长丝纱的布面效果。
