Through actual investigations, at present, the combination machine in a factory has a huge proportion require boring hole machining of parts is also a lot of volume, so Boring power head has plenty of room for development and broad application prospects.

通过实际调查，目前，组合机床在工厂中占有很大的比重，需进行镗内孔加工的零件数量也很多，所以，镗削动力头有很大的发展空间和广阔的运用前景。

The modulation of cross section is obviously,the intensity of it is smaller as the circular aperture is bigger and the intensity is bigger as the circular aperture is smaller.

平顶高斯光束经过圆孔衍射，孔径大时光强在横截面调制越厉害，但是强度小；孔径小时光强在横截面调制相对小，但是光强度相对大。

The advantage of the swirling water jet breaking rock is the heavy breaking efficiency, large breaking area and less energy used to break rock per unite volume, so the swirling water jet can drill in a hole of a large diameter.

旋转射流破岩的优势在于破碎面积大、效率高、破岩比能低，因而旋转水射流能够钻出大直径的岩石孔眼。

RESULTS:① The maximal axial pulling-out force of 10 femoral neck samples implanting the hollow nail was 471.5-1 070.5 N, with the mean value of (855.0±207.5) N; the maximal axial pulling-out strength of femoral neck samples implanting the side-hole hollow nail added by poly-methyl methacrylate bone cement was 2 023.7-3 572.1 N, with the mean value of (2 943.3±535.8) N.

结果：①置入空心钉10个股骨颈的最大轴向拔出力为471.5~1 070.5 N，平均(855.0±207.5)N；而添加聚甲基丙烯酸甲酯侧孔空心钉后最大轴向拔出力在2 023.7~3 572.1 N，平均(2 943.3±535.8)N。

The pulling out experiment was performed by AGS-10KN material testing machine to measure the maximal axial pulling-out strength of hollow nail and the maximal loading when the nail was loose during anti-bending cycle experiments.

Two pairs of chutes and holes on the cleaning base and the brushes form the double chute swing mechanisms by the connection of an axis and cause the brush to cling to the wall surface to clean by the friction feedback, thus achieving effective cleaning when walking error occurs and the pipe section changes, furthermore, the larger the friction on the wall surface is, the larger the forward pressure on the wall surface is, therefore, the dirtier the wall surface is, the higher the cleaning efficiency is.

清扫底座与刷子夹上的两对滑槽和孔通过轴的连接形成双滑槽摆动机构，并通过摩擦力反馈使得刷子能够紧贴壁面进行清洗，从而在出现行走误差和管道截面变化时都能够有效清洗，并且壁面摩擦力越大刷子作用在壁面上的正压力越大，因此壁面越脏时清扫效率越高。

After selecting base plate spring lug large cylindrical face as a rough benchmark After the leaf spring lug large cylindrical end with two holes as a precision technology benchmarks.

基准选择以后钢板弹簧吊耳大外圆端面作为粗基准，以后钢板弹簧吊耳大外圆端面与两个工艺孔作为精基准。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.

这些包括：（1） VAD 植入前心脏和大血管的检查以排除明显的主动脉反流、三尖瓣反流、二尖瓣狭窄、卵圆孔未闭或者可能引起左 VAD 植入后右向左分流的其他心脏异常，心内血栓、心室疤痕、肺动脉反流、肺动脉高压、肺栓塞和升主动脉粥样硬化疾病；并且评估右室功能；（2） VAD 植入后检查设备及再评估心脏和大血管。
