1.In this paper the floral ontogeny and the ovary development of Rivina humilis L.were observed.The results showed that (1) the tepal primordia initiated in 2/5 spirals.The abaxial one initiated first,then the adaxial one,finally the lateral two initiated nearly simultaneously.The third one initiated on the position near the first tepal,and there is a gap between itself and the second tepal.(2) The 4 stamineal primordia initiated in one whorl at the same time.(3) The carpellary primordium initiated from the abaxial side of flower primordium;the carpellary primordium grew upwards and towards axis after it was formed,therefore an elliptic orifice was formed at the adaxial position of ovary,which was the remainder of the mouth of ovary before the ovary was fused completely.With the ovary maturing,the orifice was narrowed because of the ovary growth,at last fused completely.The gynoecium is composed of a single carpel.(4) In the series developmental sections of ovary,the ovular primordium was initiated on the adaxial meristem when the mouth of ovary was formed.
对数珠珊瑚的花器官发生和子房的发育过程进行了观察.结果表明:(1)数珠珊瑚花被呈2/5螺旋状发生,远轴侧的1枚先发生,其次为近轴侧的1枚发生,最后侧方的2枚花被几乎同时发生,第3枚花被在靠近第1枚的位置发生,第2枚和第3枚之间有1个空隙;(2)4枚雄蕊是同时发生的;(3)心皮发生于分生组织的远轴侧,心皮原基形成后,向上向轴生长,在子房成熟前在近轴侧非正中位形成1个孔,该孔为心皮最终愈合前的残迹,到子房成熟时,因子房的生长孔被挤压缩小,在进一步的生长过程中愈合.子房由1枚心皮构成;(4)从子房发育过程的切片看,该植物的胚珠是在子房发生后不久发生的,子房上的圆孔形成时,从近轴侧的分生组织发生胚珠原基,由胚珠原基分化出珠被与珠心.
2.Full Size Orifice - All Series N388 valves have a full-size orifice to assure pipe size capacity. Water passages are streamline to provide high water flow with minimal pressure loss.

3.The distance between the frontal and trochlear nerves in the cranial orifice of lateral area was (2.46±0.59)mm, and the distance between the abducens and nasociliary nerves in the cranial orifice of central area was (1.96±0.72)mm, and the smallest distance between the abducens nerves of the lateral area and the optic canal was (9.32±0.85) mm in the section of the OA region.
在眶尖区断层标本上,测量额神经与滑车神经、展神经与鼻睫神经平视神经管颅口部距离分别为(mm):2.46±0.59、1.96±0.72,眶上裂中央区展神经与视神经管在颅口部的最短距离为(mm):9.32±0.85。
4.The paper have offered a simple and practical method to calculate the gas flow velocity in the bomb, with which the gas flow velocity of smoke discharging orifice and exhaust orifice in a Laser Servo-controlled Strand Window Bomb are computed. The computed results are coincide with the results measured by Laser Doppler Velocimete.

8.But now, succeasful application for the pre-stress anchor technique in the same case has been gained by use of one construction method of orifice ponding pouring in the deep excavation pit supporting in Xiamen Postal Edifice, which can be taken for example on similar engineerings.
在厦门邮电大厦探基坑支护的预应力锚杆工程中，采用一种“孔口堵水注浆”的施工方法，取得成功，可为类似工程提供借鉴。
9.We got the following suggestions, (1) the canine fossa might have occurred with the human evolution in late Pleistocene Europe, (2) there is no geographical difference for the presence of the marginal process in the fossil skulls, and (3) the bulge superolateral to the pyriforme orifice of the Dali skull seems more comparable to that of European Neandertals rather than to that of the other Chinese fossil skulls studied in this paper. This might have reflected certain degree of gene exchange.
得到如下提示 :(1 )在欧洲犬齿窝似乎是随着人类的进化逐渐出现的 ,(2 )在化石人头骨上 ,颧骨缘结节的出现似看不出明显的地域差异 ,(3)梨状孔上外侧部的膨隆这一性状似乎在大荔头骨与其他中国化石人“不融洽” ,而与欧洲尼人接近 ,这一现象可能反映了某种程度的基因交流
