In order to obtain symmetry and parallel polarized light, the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle, an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams. The distance between the triangular prism and the double Wllaston prism is changed so that the distance of the shearing parallel light can be changed.

为了获得对称且平行分束的偏振光，对双wollaston棱镜进行了修正，在获得大分束角的对称偏振光后，配合普通玻璃三棱镜，使对称分束光变成平行分束光，通过改变三棱镜与双wollaston棱镜间的距离来改变平行光的剪切距离。

The calculated results show: the ground state structures of PtNi5, Pt2Ni4 and Pt3Ni3 clusters are quadrangular bi-pyramid, and Pt4Ni2 and Pt5Ni clusters are triangular bi-pyramid with hat and triangular pyramid with quadrilateral, respectively. From the point of view of thermodynamics, PtnNim clusters are stable because of the negative enthalpy of formation; the positive NICS of PtNi5 clusters show anti-aromaticity, The negative NICS of Pt2Ni4 and Pt5Ni clusters show aromaticity. The number of the IR absorption peak of Pt3Ni3 is the most. The IR and raman absorption peak of PtNi5 , IR of Pt2Ni4, Raman of Pt3Ni3 and Pt4Ni2 have only one. The absorption peak of Pt5Ni appears in the bigger frequencies only, and is zero almost in the small frequencies.

研究结果表明：PtNi5、、Pt2Ni4、Pt3Ni3团簇的基态结构都为四角双锥结构，Pt4Ni2 和Pt5Ni团簇的基态结构分别是戴帽三角双锥和三角锥戴四边形结构；PtnNim团簇的生成焓都为负值，表明团簇在热力学上是稳定的；由NICS值可得，PtNi5团簇具有反芳香性，Pt2Ni4和Pt5Ni团簇具有芳香性；从光谱分析来看，Pt3Ni3团簇的IR较强吸收峰的个数最多，PtNi5团簇的IR和Raman、Pt2Ni4团簇的IR、Pt3Ni3和Pt4Ni2团簇的Raman只有一个强吸收峰值，Pt5Ni团簇的峰值只出现在频率较大的位置，频率小的位置几乎为零。
