Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 As shown, this set of equipment can analyze the three gases of carbon dioxide, methane and oxygen on-line at the same time, measure the recovery rate of the three gases, use the chemical reaction method to prepare quantitative gases, and then recover each gas according to the actual detection of the system. The ratio of the calculated value to the theoretically calculated value determines the detection accuracy of the open animal breath calorimetry system.

[0047] Production of oxygen: 2KO 2 +H 2 O=2KOH+2O 2 ↑;

[0048] Production of methane: Al 4 C 3 +12H 2 O=3CH 4 ↑+4Al(OH) 3 ↓;;

[0049] Production of carbon dioxide: CaCO 3 +2HCl=CaCl 2 +CO 2 ↑+H 2 O;

[0050] Oxygen is produced by the reaction of potassium superoxide and water. This reaction can be carried out at room temperature without heating, and the quant...

Abstract

The invention discloses an inspection method of the detection accuracy of an open type animal breathing calorimetric system. The inspection method comprises the following steps of: accurately weighing a certain molar quantity of chemical reagents, and placing into a breathing calorimetric chamber of the open type animal breathing calorimetric system to be inspected; respectively preparing quantitative oxygen, methane and carbon dioxide gases through a chemical reaction method to simulate an animal breathing experiment; and comparing gas recovery values and theoretical values which are actually detected by the open type animal breathing calorimetric system to determine the detection accuracy of the open type animal breathing calorimetric system. The invention has the advantages of quantitatively preparing the gases by adopting the chemical reaction method, being controllable in experimental speed, rarely influenced by external factors, high in accuracy, simple and reliable in method and high in repeatability and fast evaluating the accuracy of a detection result of the open type animal breathing calorimetric system.

Description

technical field [0001] The invention relates to a test method for the working performance of a detection system, in particular to a test method for the detection accuracy of an open animal breath calorimetry system. Background technique [0002] The use of respiratory calorimetry devices to study heat energy and substance metabolism in livestock has a long history. In the field of energy substance (protein, fat, carbohydrate) metabolism research in livestock and poultry, it is very important for evaluating the total nutritional (energy) value of feed and determining the reasonable energy requirements of livestock and poultry. , formulation of feeding standards and scientific preparation of rations, as well as improvement of feed conversion utilization, improvement of animal product quality and production efficiency, etc., all have an indispensable theoretical basis and guiding significance for actual production. [0003] my country has a vast territory, and the economic deve...
