The use of light scattering techniques can be achieved for the detection of the protein ontent of milk, but there are many factors that affect the test results in the detection process. One of the important factors effect of detection result is temperature. This article will explore the detection process temperature affect the test results and the fuzzy PID technology to achieve a milk protein detection...
The objectives of this study were to investigate the measurement methodology of the protein content in skimmed milk by laser light scattering(LLS). There was a definition that the ratio of the scattering light( at 90°scattering angles, relative to the incident beam direction) intensity to the transmitted light intensity, which was called scattered transmitted ratio(STR). Using the STR theory, we constructed...
Based on the principle of infrared radiation, the formulas of the real temperature calculation of a target surface under various conditions were derived. Thereby we obtain the real difference in temperature between two points, so that formulate expressions of the relative temperature difference. And introduce some application of infrared imaging technique in the test of the fault of low-voltage apparatus.
During production or commercialization of fine iron powder, water content is the most important parameter for evaluating and controlling the fine iron powder properties. In order to improve the portability, operability, and speed of the water determination and to reduce testing cost, a new method to quickly detect the water content in fine iron powder using capacitance type sensor is put forward....
In this paper, a set of hardware instruments used to collect arc radiant intensity in three directions were designed by using single area CCD based on high temperature characteristic of low-voltage apparatus switch arc, and the principle of computer tomogram and corresponding image processing software was also developed. We took pictures for the projection of breaking arc radiation of the low-voltage...
