转动

With the freedom in adduction and abduction motions of shoulder joint, a two-rigid-body motion system is formed.

将前臂和肱骨的联结简化为转动副，同肩关节的内收-外展自由度一同形成一个2自由度的两刚体系统。

The shoulders have rolled to their maximum and are stationary so that adduction of the upper right arm can begin.

肩部的转动达到最大并保持稳定以便于右大臂开始内收。

Trying doors as he went, twirling his club with many intricate and artful movements, turning now and then to cast his watchful eye adown the pacific thoroughfare, the officer, with his stalwart form and slight swagger, made a fine picture of a guardian of the peace.

RESULTS: Bone histological examination showed predominant hyperparathyroid bone disease in 6 patients, mixed uremic osteodystrophy in 3 patients, low-turnover osteomalacia in 1 patient, and adynamic bone disease in 4 patients.

结果： 骨组织学检查的诊断出 6个患者有严重的骨组织形态学疾病，3个患者的混合尿毒症的骨发育不良，1个患者的低转动骨软化，和 4个患者的无力骨疾病。

Before he learned this, however, he found that moving more than one feather at that speed will spin you like a rifle ball ... and Jonathan had flown the first aerobatics of any seagull on earth.

他在学到这一点之前，还发现在那样的速度下，只要转动一两根羽毛就可以像陀螺似地旋转……于是乔纳森成了世界上第一只做特技动作的海鸥。

The kinds of compounds with AIE, AIEE and CIEE are summarized, mainly including siloles, substituted ethenes (mainly including fulvene and DPDSB style), CN-MBE, pyran, biphenyl compounds and polymers.

侧重总结了silole型、取代乙烯型（主要包括亚甲基环戊二烯型和DPDSB型）、腈取代二苯乙烯型、吡喃型、联苯型等小分子化合物和少数高分子的结构与AIE性质之间的关系，以及为解释AIE现象所提出的限制分子内的转动、避免非辐射去活、构象扭曲避免形成excimer、J－聚集态以及形成分子间的C-H/π键等理论。

The mainly working elements are: crankshaft and clamp are built on the imovable table-board. The headstock has aiguille and it follows dragging board to come true the boring athletics.The landscape orientation of dragging board, the up and down sport of shaking-arm and the running of dragging board turn up the modulating of working station.

其大体工作原理如下：曲轴和夹具安装在固定不动的平台上，装有钻头的主轴箱随进给拖板实现钻削进给运动，工作位置的调整是通过大拖板横向运动、摇臂的上下运动、摇臂的转动来实现的。
