Third installation at laporte , indiana . earliest use of switch with semi - cylindrical bank and shaft with vertical and rotary motions . invention of earliest dial - type calling device 印第安纳州拉波特完成史端乔系统第三次安装。最早使用具有半圆形排线架的交换机和具有垂直和旋转运动方向的轴。发明早期拨号型呼叫设备。
( 7 ) the non - linear motion of global plate is studied in detail using continuous gps time series , and the temporalvariablefeature of plate euler rotation motion is firstly presented internationally （ 7 ）用连续观测的gps时间序列资料详细地研究了全球板块的非线性运动，在国际上首次给出了全球板块欧拉旋转运动的时变特性。
The first revolution happened when nicolaus copernicus no longer saw the earth as a motionless point at the centre of the universe but as moving in “ revolutions ” , or circles , around the sun 当尼古拉斯?哥白尼不再把地球看作是宇宙中心一个静止不动的点，而是围绕太阳作旋转运动，或者可以说是绕着太阳转圈时，第一场革命爆发了。
It is composed of two components : level move and rotation . level move is realized by the co - operation of oil vat , handspike and synchronizer . rotation is realized by the brace and the triangle oriented axis 平行移动是由液压油缸推动，通过推动轴承传到推杆、同步盘，并相互配合实现的；旋转运动是由曲柄、三角架导向轴完成的。
This paper makes a preliminary discussion on the possible genesis of such rotation movement , as well as the associated series of geologic processes and its relation to large - scale metallogeny in hunan province and adjacent regions 本文对这种旋转运动的可能成因，以及所伴随的一系列地质作用、与大规模成矿作用的关系等进行了初步探讨。
When the shaker is working , its roller screen not only vibrates with the shaker deck , but also slowly rotates with the axis of itself , and the drilling fluids returned from annular space are separated inside the roller screen 工作时筛网筒与筛箱一起振动，同时还绕自身轴线作缓慢的旋转运动，从环空返回的钻井液进入筛筒内部进行分离。
This microstructure stimulates the piezoelectricity thin film rocking bar using the oscillating circuit to have the vibration , rocking bar impetus slide around translational motion , simultaneously tows the crank to have the rotary motion 该微结构?用振荡电?激发起压电薄膜摇杆生成振动，摇杆带动?块前后直线移动，同时牵引曲柄生成旋转运动。
The study indicates that erf couplings could be conveniently controlled , intermittent rotation could be easily obtained . it is expected that the erf coupling could be used in flexible transmission systems 实验结果表明电流变液具有很好的控制性能，可以很方便实现旋转运动的间歇进给，并且输入和输出之间是柔性连接,可以应用于柔性旋转间歇运动机构。
The pole is attached at the one end to an upright post , around which it can revolve , and at the other to a blind - folded camel , which walks constantly in a circle , providing the motive power to turn the stone wheel 译文：滚轴的一端与一根立柱相连，使石磙可以绕立柱作旋转运动，另一端则套在一头蒙着眼罩的骆驼身上，通过骆驼不停地绕圈子走动来带动石滚旋转。
Polarization diversity and maximum ratio combining ( mrc ) is used to restrain the sharp signal fading in the telemetry systems , in which the object is in flight at a high speed and rotating and in low elevation 在信号极化衰弱现象严重的环境中对快速飞行目标、低仰角运动目标以及旋转运动目标等进行遥测接收时,极化分集最大比合成技术可以有效的改善接收性能。
