向左侧卧，用左手检查右边乳房，而右手肘向上曲伸，手臂要与肋骨成 90 度。

Backgrounded by the main bridge of Zhanhe River Bridge at Chengdonghe Road,Pingdingshan City,the software MIDAS/Civil is used to establish a 3-dimensional finite element calculation model for the double X-shape arch bridge and the effect of arch rib sloping angle changes on the dynamic performance of the type of the bridge is studied respectively for six design alternatives.

以平顶山市城东河路湛河桥主桥为工程背景，采用有限元软件MIDAS/Civil建立该桥的空间有限元计算模型，分6种设计方案研究了拱肋倾角变化对斜靠式拱桥动力性能的影响。

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.

为提高机械钻速，引进贝克休斯的VTK垂直钻井技术，它是由AUTOTRAK、高性能X-TREME马达、可靠的MWD三种技术开发出来的一种闭环自动垂直钻井技术，能够根据井眼的偏斜，经井下微处理器分析判断，使导向稳定地靠近井眼高边方向导向肋板伸出顶向上井壁，这样使钻头产生合理的降斜力，从而使井眼回到垂直轨道上来。
