It is found that the portion of edge areas of cuboidal γ'precipitates grew preferentially and the γ-γ'interfaces progressed concavely,which was followed by the enclosure of the adjacent vertical matrix channels (parallel to [001]), and the linked γ'precipitates gradually exhauseted the retained vertical channels and finally developed into rafted plates.
发现在定向粗化期间立方形γ＇沉淀的边缘部分优先生长，γ—γ＇界面呈内凹形方式推进，进而封闭了与之相邻的垂直基体通道（平行于［001］）；相互连接的γ＇沉淀逐渐消耗并最终耗尽被封闭的残余垂直通道而发展成完整的筏形组织。

Based on the former drag reduction experiments of the bionic nonsmooth body of revolution models in the lowspeed wind tunnel, the simulation wind tunnel tests at the wind speed of 44 m/s were performed for the body of revolution models with the tail rectangularly disposed by three different nonsmooth structures, such as the convex dome form with the diameter/height of 1.0/0.5 mm, the dimple concave form with the diameter/depth of 1.0/0.5 mm, and the riblet form with the width/height of 1.0/0.5 mm, in contrast with the body of revolution model with smooth surface.
在前期进行的仿生非光滑旋成体模型低速风洞试验的基础上，将非光滑形态在旋成体模型上的排列方式固定为矩形布置，非光滑的尺寸固定为直径或宽度为1 mm，深度或高度为0.5 mm，在风速为44 m/s时，对布置在模型尾部的凸包形、凹坑形和棱纹形三种非光滑模型与表面光滑模型进行了对比模拟试验。

Cordate Heart-shaped, usually referring just to the base of leaves, e.g.
心形：心形的叶片，与卵形相似，但叶片下部更为广阔，基部凹入成尖形。

The family is characterized by a primitive protrogomorphous-sciurognathous zygomasseteric structure and pauciserial incisor enamel, but the cheek teeth are precocious in development of hypocone and hypolophid.
共 4属 6种。新科的特征是：始啮型头骨-松鼠型下颌；门齿釉质层散系；颊齿具有发育的次尖和下次脊，后期种类上颊齿的外侧齿尖的唇侧发展成平凹到新月形。

A high-strength steel pipe rockbolt has an expansive rockbolt main body prepared by processing a high-strength steel sheet of 1.8-2.3 mm in thickness with tensile strength of 490-640 N/mm 2 and elongation of 20% or more to a welded pipe and roll-forming the welded pipe to a shaped pipe having one or more concavities extending along an axial direction.
高强度钢管锚杆具有可膨胀锚杆主体，该主体通过下列步骤制成：将抗拉强度为490～640N/mm 2 ，伸长率为20％或更大，厚1.8～2.3mm的高强度钢板加工成焊接管，再将该焊接管滚轧成型成具有一个或多个沿轴向延伸的凹部的异形管。

metencephalon：后脑
在胚胎第六周之初或长约9mm时又出现第三个凹向背侧的弯曲,称桥曲,这样就把菱脑分为后脑(metencephalon)和末脑(myelencephalon)(图10-4B). 在长约5mm的人胚,前脑与中脑开始能明确分开,同时,脑前壁在视泡前方和上方向背侧膨隆而成大脑半球初形.

promontory：骶岬
每块髋骨又由髂骨(ilium)、坐骨(ischium)及耻骨(pubis)融合而成;骶骨由5~6块骶椎融合而成,其前面呈凹形,上缘向前方突出,形成骶岬(promontory),骶岬为骨盆内测量对角径的重要据点;尾骨由4~5块尾椎合成.

bothrium：沟槽
假叶目绦虫头节呈梭形,其固着器官是头节背、腹侧向内凹入而形成的两条沟槽(bothrium). 绦虫即靠头节上的固着器官吸附在宿主肠壁上. 此外,当孕节在所寄生的宿主肠中被消化而释出虫卵时,亦可孵出六钩蚴,然后钻入肠绒毛发育成似囊尾蚴,
