摘　　要：以常规精密数字温度温差仪、计算机等研制了基于LabVIEW 8.0测定中和热的虚拟仪器系统,运用于测定氢氧化钠与醋酸反应的中和热的结果表明:基于LabVIEW开发的虚拟仪器系统使常规的仪器性能获得智能化的提升,避免人工操作、记录和数据处理的人为误差,提高了测定结果的准确度和重现性,且具有界面友好,操作性强,功能易扩展等诸多优点.The virtual instrument system based on LabVIEW 8.0 has been developed on the foundation of conventional precise temperature-temperature difference digital equipment, computers and others for measuring the neutral heat of reactions between the sodium hydroxide and acetic acid. The result indicates the virtual instrument system developed on LabVIEW can make conventional equipment intelligent. It avoids mistakes by human operation or hu- man data recording and data-processing by handwork. The accuracy and recurrence of experimental result are greatly improved. This program is interface-friendly, easy to operate, easy- extending and many other advantages.
