Benefits of technology

The inventor describes an improved testing apparatus that uses infrared light waves instead of visible lights to measure properties such as temperature or pressure accurately over short distances without being affected by external factors like weather conditions during measurement time periods. This results in more accurate measurements than traditional methods while also reducing costs associated with these tests compared to other techniques used today.

Problems solved by technology

Technological Problem addressed in this patents relates to improving the performance of solid-lipide composite fuels without increasing their weight or making them heavier than usual due to the presence of certain substances like water vapor. Existing methods involve adding thick layers of insulating agents between the two phases of the composition, but these techniques may result in increased stresses caused by buckling deformation over time. To address this issue, new ways were proposed involving filling the space within the combustion chamber with a gelatin solution called hydraulic oil mixes instead of directly injecting the hydrogen fuel. However, existing methods require multiple steps beforehand, leading to potential issues related to incomplete coverage of the entirety of the fill area.

Abstract

The invention discloses a testing device and a method for determining system uniformity by using a near-infrared spectrometer. The method comprises the following steps: testing a solid-liquid-gas phase mixture 5 by using the near-infrared spectrometer, determining that the solid-liquid-gas phase mixture 5 is uniform when the highest peak difference is within 0.95%, marking the position of the upper end surface of isobaric liquid 6, and heating the solid-liquid-gas phase mixture 5 to a set temperature, so that the upper end surface of the isobaric liquid 6 moves upwards gradually; rotating a piston 7, enabling the seventh lower end circular plane of the piston 7 to move downwards, and compressing the space of an isobaric gas 8. According to the method, gelatinized solid-liquid-gas phase mixture volume expension pressure is converted into elementary substance liquid pressure, and converted into elementary substance gas pressure. Therefore, the measurement of the volume expansion pressureof the gelatinized solid-liquid-gas phase mixture is realized.
