目的　研讨完全由计算机控制的Maclab系统在Langendorff逆行灌注装置中的应用。方法　根据实验要求编辑“设置文件” ,每次实验时只需打开“设置文件”即可进行操作。实验结果为数字化数据 ,直接调入统计或其他程序进行处理。结果　实验装置简化 ;采用“设置文件” ,操作简便 ;测量精度达满量程 0 .1% ,远优于传统方法。结论　数字化的计算机处理提高了实验的可靠性 ,计算机对实验资料的完整存贮有利于资料的进一步利用 Objective To investigate the application of a completely computer-controlled Maclab system in a Langendorff retrograde perfusion device. Method According to the experimental requirements to edit “settings file”, each time you just open the “settings file” to operate. The experimental results for the digital data, directly transferred to the statistics or other procedures for processing. The results of the experimental device simplified; the use of “set file”, easy to operate; measurement accuracy of full scale 0.1%, far superior to the traditional method. Conclusion Digital computer processing improves the reliability of the experiment. Computer’s complete storage of experimental data is conducive to the further use of data
