When one studies the progenitor models of SNe Ia, the dependence of the mass of CO WD on metallicity i.e.

在本文中，我们也研究了恒星在零龄主序时的质量与其演化成白矮星后的质量之间的关系(以下简称初始-终止质量关系)随金属丰度的演化。

Of the 19 cases,19 fetus were found,MRI confirmed 14 cases considered or suspected as fetal corpus callosum agenesis by US(8 cases are completed agenesis of corpus collosom-CACC,6 cases are partial agenesis of corpus collosom-PACC, and 5 cases had took on autopsy),however 3 cases are mild enlargement of lateral cerebral ventricle and 2 cases are leukodystrophy.In these cases,MRI confirmed a Dandy-Walker syndrome and a lipoma of corpus callosum suspected by US,detect a Dandy-Walker syndrome and a microcephalus made missed diagnoses by US.The fetal corpus callosum and additional cerebral anomalies were shown more clearly on MR T_2-weighted images.

胎儿胼胝体长度与额枕径的比值在24～36孕龄阶段相对较恒定。2、19例孕妇共检出胎儿19个，MRI证实超声疑诊的胎儿胼胝体发育不全14例(完全型胼胝体发育不全8例，部分型胼胝体发育不全6例，有胎儿尸检结果对照者5例)，3例为单纯侧脑室轻度扩张，2例考虑脑白质发育不良，合并Dandy—Walker综合征1例，胼胝体脂肪瘤1例，检出超声漏诊合并Dandy-Walker综合征1例及脑小畸形1例。

In order to explore the role of cytochrome c oxidase during the development of Microtus brandti, the activity of mitochondrial CcO and content of mitochondrial protein in voles＇ liver was measured by using ultraviolet spectrophotometry, these voles were chosen according to days.

为探讨线粒体能量代谢中细胞色素c氧化酶（cytochrome c oxidase，CcO）在布氏田鼠生长发育过程中的作用，应用紫外分光光度法测定了不同日龄的幼鼠肝脏内线粒体蛋白含量及CcO活性。

Olfactory bulb was abstracted to culture the human fetal OECs, and the monoplast suspension were made and cultured in the uncoated culture flask.

选用流产胚胎标本24份，胎龄4~6月，由西安交通大学第二医院和陕西省妇幼保健院产科提供。

myelinic degeneration obviously existed and abnormal MRI appeared in caudate putman only in older rats with chronic hypertension.

慢性高血压大鼠直到鼠龄较大时，尾壳核区域出现明显的髓鞘变性，才在MRI上显示出来。

Objective:To evaluate the MRI features of normal brain myelinization in neonates and infants at various stages of development.

目的：应用高场MR仪研究正常小儿不同月龄段的脑髓鞘与对应MRI信号特征。

The signal intensity characteristic of MRI associated with brain myelinization is helpful to differentiate the normal and abnormal brain maturation.Also,T1WI is much more useful in the detection of immature myelin and in monitoring of normal brain development in the first 6 months of life.On the other hand,T2WI is more useful after 6 months of life.

不同月龄段不同解剖部位正常脑髓鞘化具有各自MRI信号特征，有利于评判是否脑发育正常和患脑白质病，T1WI评估未成熟髓鞘较好，T2WI确定髓鞘是否成熟较好。
