At present silkworm cocoons, dried, boiled and reeled, are the female and male mix, so it's very difficult to produce high grade raw silk in large quantity. In the progress of the silk reeling what we can do to separate the complex of female and male silkworms still encounters presently certain difficulties. In this paper the intrinsic relaxation time of the free water and the bound water in silkworms...
Oil content is one of the important parameters of quality control in oilseeds. How to realize the simultaneous determination of oil content has come to professional's attention. In this work, the feasibility of solving this problem by Pulsed Nuclear Magnetic Resonance is proved, with the help of Bloch Equation in NMR theory. Based on the feasible demonstration, the new system is designed for simultaneous...
Variable temperature detector is the key component in developing the application of low resolution nuclear magnetic resonance analytic instrument. Because of the small volume, low power loss and controlled expediently, the semiconductor frigorific flake is used widely in each frigorific occasion. The research takes the semiconductor frigorific module to develop the variable temperature detector. We...
According to the specialties of mini-type magnetic resonance imaging instrument, the authors developed more than 30 teaching experiment projects on medical imaging. Because of its open hardware configuration, these experiment projects have clear processes. Furthermore, some testing researches and analyses on characteristics of biology tissues and food samples have been done. Using this instrument,...
