The second member is coaxially aligned with and is engageable with the first end of the tubular member.

第二部件与管状件的第一端同轴地对准并可与之啮合。

Methods Nineteen bone impacted and unerupted teeth in 18 cases selected by orthopantomograph were scanned by 3DX-CT with 1.0 mm slice thickness. Images obtained by 3DX-CT (horizontally, sagittally, coronally) were analyzed after multi-plane reconstruction and 3D reconstruction including the angle of the bone axis impacted and unerupted teeth; maximum radius of the coronal teeth; distances between the tooth and the cortical bone around; distances to the neighboring tooth roots and nerve forum canal; the thickness of the bone tissue, etc.

对经曲面断层片筛选出的18例19枚埋伏牙进行牙科三维CT检查，扫描层厚1.0mm，重建后进行图像三维断面显示（包括水平位，矢状位，冠状位），对牙位图像进行分析及测量（包括埋伏牙牙长轴的角度，牙根弯曲度，牙冠的最大径，与骨皮质的距离，与邻牙根、神经孔／管的距离；骨质的厚度、高度等）。

At present, regeneration system of cotyledons, hypocotyls, and stems, protoplasts and cotyledons codes have been established among Cucurbitaceae. There are several methods of transformation, such as agrobacteria -medidated genetic, particle gun, pollen tube passage, DNA soaking, ovary embryonary sac injection. Transgenic is tending to antivirotic and delayed maturity. Selection marker used often is NPT II.

目前，在葫芦科植物中已建立了子叶、茎尖、胚轴、茎段、原生质体和子叶节等的再生体系；用于遗传转化的方法有农杆菌介导法、基因枪法、花粉管通道法、DNA浸泡法等；用于转化的目的基因多为抗病毒病基因和延迟成熟的基因；NPTII基因为最常用的筛选标记基因。

It is found that the modified delaminate model in account of circumferential damage is able to well describe the progressive failure of the tubes subjected to axial compressive loading.
