In order to compare the tribological properties of two aluminum matrix composites reinforced by different content of B4C particles ,the pin samples were prepared with them and friction and wear tests of pin-on-steel disc were carried out on a multifunctional tribometer.

为了比较两种含量不同的碳化硼颗粒增强铝基复合材料的摩擦学性能，将其加工成销试样，在多功能摩擦磨损试验机上分别与钢盘试样进行对比摩擦磨损试验，重点研究了接触载荷和相对滑动速度对两种复合材料摩擦磨损性能的影响。

In order to improve the fire safety and reliability of an explosive device, a butterfly metal film bridge was prepared by adopting a magnetron sputtering technology with a mask. The bridge surface was smeared by 15-20 mg lead styphnate. The current safety testing, antistatic testing and the bridge wire comparative testing were used to study its properties of safety and ignition. Infrared thermal imaging technology was used to verify the heat distribution of the thin film bridge.

为了提高火工品的安全性及点火可靠性，采用掩模法，利用磁控溅射技术制备了一种蝶形金属薄膜桥，在薄膜桥表面涂15~20 mg斯蒂芬酸铅，进行了安全电流试验、抗静电试验及与桥丝的对比试验，研究了其安全性能和点火性能，并利用红外热成像技术验证其发火时桥区的热分布。

As a numerical example, the CRAIGs and CDAIGs for the S EGEAGE 2D salt model are calculated and analyzed. Based on their distinct feat ures, the applications of these two CIGs to seismic imaging are discussed in det ail

以SEGEAGE二维盐体模型为例，通过对CRAIG和CDAIG的对比，探讨了这两种角度域CIG的特点及其在地震偏移成像中的潜在应用。

many layer spiral the CT MPR combine a 3 D-SSD, VR be like can explicit diagnosis Han face bone fracture, can keep view ground understanding Han face bone fracture at 3D stereoscopic space of actual size, appearance position and surroundings structure of dissect relation, and for it clinical treatment provide basis, to Han face bone fracture before the Shu establishment surgical operation project and before the Shu, Shu empress contrast all have importance of instruction function.

多层螺旋CT MPR结合3D-SSD、VR成像能够明确诊断颌面部骨折，可直观地了解颌面部骨折在三维立体空间的实际大小、形态位置及周围结构的解剖关系，并为其临床治疗提供依据，对颌面部骨折术前制定手术方案和术前、术后对比均有重要的指导作用。
