1) limited square column
有限长方柱
2) finite-length prism
有限长柱体
3) unlimited square column
无限长方柱
1.
Then a calculation was represented,the transient responses were plotted of unlimited square columns,and the propagation waves in limited and unlimited columns were compared.
提出行波追踪方法,在以前工作中得到解析形式的频散方程、群速度方程和稳态响应的基础上,完全得到无限长方柱在任意外力作用下解析形式的瞬态响应。
4) finite cylinder
有限长圆柱体
1.
The backscattering and forward sca-ttering functions of finite cylinders with hemispheroidal end caps,which have different ratio of length to width or different geometric end caps,were calculated.
以两端有半椭球顶的有限长圆柱体为例,分别计算了具有不同长宽比或者是不同端部几何形状的有限长圆柱体的反向散射和前向散射函数。
5) Finite length cylindrical shell
有限长圆柱壳体
补充资料:天柱山天柱峰
天柱峰又称为皖伯尖,万山尖。《道书》称为司命真人发祥所都,海拔1488.4米,孤立晴宵,顶天立地,石骨嶙峋,峭立如柱。五指、莲花、天池、含珠、飞来、月华诸峰拱卫左右,奇松、怪石、云海、佛光、各领风骚。李白《江上望皖公山》诗云:“奇峰出奇云,秀水含秀气。”白居易《题天柱峰》诗云:“天柱一峰擎日月,洞门千仞锁云雷。”
