This system can change the synthetic wavelength chain according to the distance to be measured. The inphase state of the interference signals, which is difficult for phase measurement, can be avoided by changing the wavelength freely. In addition, this system can realize the dimension calibration between the workpiece and the gauge block at a shortest measuring chain.

This thesis contains three parts: The first part focused on the simulation of the dynamic buckling for rod impacted by dynamic force and rigid body in axial direction, which is hinge joint and uniform cross section, basing on the ANSYS/LS-DYNA and PAMCRASH.

本文的研究工作主要有三部分组成：第一部分基于有限元程序ANSYS/LS-DYNA、PAMCRASH分别对两端铰接、等截面直杆在轴向动力载荷作用下的屈曲和刚性块轴向冲击作用下直杆的动力屈曲过程进行了数值模拟和分析。

It has been found that during the spark plasma sintering process, under the condition of large current, short sintering time and lower sintering temperature, the metastable icosahedron quasicrystal phase in primary powder particles is kept. And the strong discharge plasma among particles can decompose or break the oxide film on the primary powder's surface, resulting in the increment of their combination strength. So the as-prepared bulk alloy possesses high density and ultra-high strength.

结果表明，在放电等离子烧结过程中，采用大电流、短时、低温的烧结条件可使快冷雾化法制备的原始合金粉末中的准晶强化相及其它细小强化相得以保存，而局域强放电等离子体可以分解或破碎铝合金粉末表面的氧化膜，使合金粉末颗粒间的结合强度增加，制备出的块体铝合金具有高的致密度和超高强度。
