摘　要:針對(duì)傳統(tǒng)液體表面張力測(cè)試儀的不足，研發(fā)了一種基于虛擬儀器技術(shù)的液體表面張力測(cè)試儀，并詳細(xì)闡述了測(cè)量原理及其系統(tǒng)的實(shí)現(xiàn)方法。測(cè)試結(jié)果表明該測(cè)試儀可實(shí)現(xiàn)液體表面張力自動(dòng)測(cè)試，讀數(shù)時(shí)間短，有效避免了人為讀數(shù)誤差的影響，測(cè)量結(jié)果的一致性較好。[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]
