摘要： The invention provides a preparation method of high-content Ganoderma lucidum β-glucan and an efficient and rapid detection method thereof. The preparation method comprises ethanol-trypsin pretreatment of Ganoderma lucidum fruiting body in combination with ultrasonic-assisted alkaline hydrothermal extraction of β-glucan from Ganoderma lucidum, and purifying β-glucan by DEAE Sephadex A-25 Sephadex column chromatography using NAOH solution as a mobile phase, to obtain high purity (≥90%) of Ganoderma lucidum β-glucan. The detection method comprises placing the extracted β-glucan in an autoclave and performing hydrolysis with β-(1,3)-exo-glucanase and β-glucosidase, and detecting and analyzing the content of the prepared β-glucan by high pressure-acid enzymatic hydrolysis-HPLC method, using glucose as a standard. The preparation method of β-glucan has high extraction ratio. The efficient and rapid detection method has high sensitivity, high accuracy and good repeatability, and thus has a wide application prospect.

摘要： A stable and reliable built-in cross-coupled dielectric filter with temperature-independent performances and improved rectangular degree and amplitude-frequency characteristic is disclosed. The built-in cross-coupled dielectric filter comprises at least three sequentially welded coaxial dielectric resonators. Mutually coupled capacitors or mutually coupled inductors are etched on the two adjacent lateral surfaces of the adjacent coaxial dielectric resonators, respectively, with an alternate setup. The input and output ports of the built-in cross-coupled dielectric filter are positioned at the two coaxial dielectric resonators at the head and tail, respectively. The present invention is particularly applicable to the high-frequency realm such as microwave.
