摘要炸药爆温是指炸药爆炸时放出的能量将爆炸产物加热到的最高温度。爆温是评价炸药性能的重要参数，也是炸药爆轰理论及爆轰产物状态方程的热化学计算中的一个重要指标。爆炸温度场的测量对研究爆炸过程中的热传导、温度分布规律是十分必要的，可为炸药和相关弹药的威力考核与分析提供依据，具有重要的意义。
根据爆炸温度场的特点，经过分析比较，采用0.1mm丝径的钨铼5-钨铼26偶丝作为测温传感器，并设计了热电偶的冷端补偿电路，建立了基于PXI总线的数据采集系统，采用图形化应用软件LabVIEW编写了专用的数据采集和处理软件，实现了参数设置、数据采集、数据处理、生成报表等功能。6428
测试结果表明本系统满足实际测试需求，硬件组建合理，软件具有良好的人机交互性，符合工作人员的操作习惯。

Title  The test system of explosion temperature field based on the  LabVIEW
Abstract
Explosive detonation temperature is refers to the explosive gives off energy explosion heated to the highest temperature of the product. It is not only the important parameters of performance evaluation explosives, but also an important index of the explosive detonation theory and detonation product state equation of heat in the calculation of the chemical .Currently in the field of ammunition destruction, the temperature measurement and research on temperature distribution of explosion field provide the basis for explosives and ammunition on the power of evaluation and analysis, is of great significance．
In case of the features of the explosion temperature field, after analysis and comparison, using the 0, 1mm-thermocouple tinsel of WRe5-WRe26 as a temperature sensor, and designing the thermocouple cold junction compensation circuit, building the data acquisition system based on PXI. The thesis uses the graphic software LabVIEW to design the software system, and software system chooses the modularized design. The software system has the function of parameter setting、file save、waveform display、static calibration.
The result shows that the integrated test system of dynamic parameter has satisfied the requirement of practical test；The building of hardware is reasonable and it has high ratio of performance to price. The software system has good man-machine conversation interface, and it meets with the operation custom of the operators.
Keywords: Thermocouple, Explosion temperature field, software program, PXI instrument, LabVIEW.
