Fontanelle at birth, there are two major: a skull that static in the front of heads from both sides of the parietal bone and frontal bone-phase before the corner formed at birth oblique diameter of 2.5 cm, usually in 1 ~ 1. 5-year-old closed; fontanelle after another said, by the parietal bone and occipital bone and the composition of the transition, in the back of the head, the general was born on a small or closed, the latest in 2 to 4 months after closing.

囟门在出生时主要有两个：一个称静囟，在头顶前部，由两侧顶骨前上角与额骨相接而组成，出生时斜径为2.5厘米，一般在1～1.5岁闭合；另一个称后囟，由顶骨和枕骨交接而组成，在头顶后部，一般出生时就很小或已闭合，最晚在2～4个月时闭合。

AIM: To study the effect of tumor necrosis factor-α on the expression of matrix metalloproteinases in the cultured bovine trabecular cellsand approach to pathogenesis and mechanism of primary open angle glaucoma.

Thirdly, by con-utilaziont of many methods such as exploitation and geology, dynamic producing process monitoring, water invasion behavior, core analyis and numerical simulation, 10 kinds of reservoir scale remaining oil distribution pattern in the steam huff and puff super heavy crude oil reservoir was put forward. Also, remainling oil distribution in the sand bed scale and sublayer scale were pointed out.Fourthly, Microcosmic displacement experiment was conducted for hot water driving in 100℃and 120℃. and steam drive at 170℃condition. Microcosmic remaining oil distribution characteristics were summarized. Remaining oil microcosmic distribution by steam drive at 170℃is different from that at 100℃, 120℃hot water driving. After the steam drive, there are three types of remaining oil distribute regular pattern, whic is impacted by many affecting factors like pore configuration, wettability and interfacial tension.

分析了砂层组规模和小层规模的纵向和平面剩余油分布规律。4、通过微观驱替实验，研究了100℃和120℃的热水驱及170℃蒸汽驱条件下剩余油的微观分布形态。170℃条件下剩余油微观分布形态同时受孔隙结构、润湿性及界面张力多种因素的影响，主要有三种形式：在油、汽、水三相共存的孔隙中，剩余油分布于汽、水之间，为薄膜状和弯月状；在只有油、汽两相共存的孔隙中，大孔道中主要是蒸汽，剩余油在细小的孔喉和孔隙角隅处以段塞或不规则状态存在；由于高温水蒸汽对原油具有萃取作用，剩余油以一种细小的珠滴状存在于孔隙表面。
