【摘要】 为满足畜禽能量物质代谢科研领域进一步深入发展要求,对国际上已被广泛应用的传统"开放回流"呼吸测热装置进行了工艺技术改进,于2005年自行设计并采用国产有关仪器仪表和自行加工等部件,研制组装一台技术工艺较为先进的中型开放回流呼吸测热装置。采用电动系统(各种传感器)与微机相结合的方法,使该装置基本达到全部自动控制水平。可以测得在实验期间全程(在线)或各不同阶段(单项)的气体交换及能量代谢等多项内容指标与结果。更多还原

【Abstract】 In order to satisfy the developmental requirement of scientific research for metabolism of energy substances in farm animal the process technology of an open circuit respiratory apparatus which had been extensively applied was impro-ved. A advanced medium open circuit respiratory calorimetry apparatus was own-designed and own-installed with the na-tional-made instruments, meters and own-made parts. This equiment basically achieved the entire auto-control level by using the method that the electric system (several kinds of sensors) combined with the computer. It could measure many content indices and results during the whole period (on line) or at different stages (single), such as gas exchange and energy metabolism.更多还原
