摘　要:针对传统液体表面张力测试仪的不足，研发了一种基于虚拟仪器技术的液体表面张力测试仪，并详细阐述了测量原理及其系统的实现方法。测试结果表明该测试仪可实现液体表面张力自动测试，读数时间短，有效避免了人为读数误差的影响，测量结果的一致性较好。[著者文摘]

Design of liquid surface tension testerWANG Wan-gang,SONG Wen-wu,ZHANG Jian-hong1.School of Electrical Engineering,Southwest Jiaotong University,Chengdu 610031 ,China; 2.school of Power and Environment,Xihua University,Chengdu 610039,China; 3.Chengdu Textile College, Chengdu 611731, China; 4.Chengdu Dongsheng Packing Materials Co., Ltd,Chengdu 611731,ChinaAbstract:Based on virtual instrument technology, one kind of liquid surface tension tester was developed to overcome those deficiencies of traditional liquid surface tension testers. And its measuring principle plus the method to construct this system were described in detail. The measurement results indicated that this instrument could be used to automatically test liquid surface tension. And its reading time was very short, which would reduce those errors induced by human reading, effectively. In addition,the consistency of measurement results was very well too.[著者文摘]
