The method of relating the gauge potential to the connection on a spherical surface developed in a previous paper is generalized to the discussion of the potential of an SU(2) magnetic monopole with O(5) symmetry. Expressions for the potential of the monopole with double string singularity or single string singularity are obtained. Finally, by a combined coordinate-gauge transformation, we obtain a string free expression for an SU(2) magnetic monopole with O(5) symmetry.

本文把我们在前一工作中所发展的使规范势与球面上的联络相对应的方法推广于讨论有O(5)对称的SU(2)磁单极势,得到了有双弦奇异性及单弦奇异性的磁单极势的表达式.最后通过一个坐标-规范联合交换,得出了无奇异弦的,有O(5)对称的SU(2)磁单极规范势.

Three designing strategies of vibrating string type electronic balance with single string and dual strings are introduced concretely. Based on the analysis for the features of three designing strategies, the author states that dual strings structure is a good concept to make non-linear compensation and reduce temperature effects of environment.

分单弦式和双弦式两种不同结构,具体介绍了振弦式电子天平的三种设计方案。在分析三种方案特点的基础上,指出双弦结构是解决非线性补偿和减少环境温度影响的一种好构思。

A new method of hole diameter measurement by two strings, which can include the traditional turning point method and symmetry points method, is discussed by modelling. The measurement error of this method is larger than one of symmetry points measurement and smaller than one of turning point measurement when l 1 and l 2 are located at two sides of the maximum diameter line. The scanning error can also be neglected when H/D is from 0.025 to 0.05.

讨论了一种新型的孔径测量方法双弦法,建立了测量模型,指出传统的转折点法、对称点法是其特例。若l1,l2分布在孔两侧,合理选择H/D,可以减小扫描误差的影响。最后讨论了利用双弦法对工件进行Z向微米级定位。根据此原理,很容易实现精密孔径测量仪器的智能化、高准确度和高效率。
