1) the biggest inside positve four prism
最大内接正四棱柱体
2) the smallest outside positive four prism
最小外接正四棱柱体
3) inscribed prism
内接棱柱
4) regular prism
正棱柱体
1.
This thesis finds an approximate solution of the natural frequency to the regular prism in quiescent fluid by the perturbation method, hence avoiding the difficulties in finding its exact solution by a direct way.
本文用摄动法求解了二维正棱柱体在静止流体中固有频率的近似解,从而避免了直接求其精确解所遇到的困难。
5) maximum inscribed cylinder
最大内接圆柱
1.
The measured cylinder can be randomly placed,sampling points in rectangular spatial coordinates and all discrete data can be sampled optionally,and the minimum zone cylinder(MZC),the minimum circumscribed cylinder(MCC) and the maximum inscribed cylinder(MIC) errors can be evaluated simultaneously in the error evaluation method.
在任意位置放置、直角坐标采样、各离散采样点之间不要求为等角度间隔情况下,建立了可同时实现圆柱度误差的最小区域法、最小外接圆柱法和最大内接圆柱法评定的坐标变换法评定模型。
6) prism forward calculation
棱柱体正演

经皮经颈静脉肝内门体静脉内支架分流术
介入放射学技术。也称经皮经颈静脉肝内门体静脉分流术(TIPS),1969年最初由Rosch等首先报道。经颈静脉送入导丝,于门-腔静脉间经肝实质建立通道,并放入支架以形成永久性分流径路的治疗方式,以降低门脉压力,治疗顽固性的食管胃底静脉曲张出血及顽固性的腹水。该技术除常规导丝、导管、球囊扩张导管等外,需向建立的分流通道内置入支架,常用的有Z-型支架、Wallstent支架、Strecker支架等。
