The invention discloses a method for detecting wind-cold cold granules. The method comprises thin layer identification of Chinese ephedra and platycodon root and content determination of ephedrine hydrochloride, wherein identification of the Chinese ephedra is performed by taking ephedrine hydrochloride as a reference substance and a mixed solution including ethyl acetate, methanol and water as a developing agent and using a thin layer chromatography; and the identification of the platycodon root is performed by taking a platycodon root contrast medicinal material as a reference substance and a mixed solution including n-hexane, ethyl acetate and glacial acetic acid as a developing agent and using the thin layer chromatography. By adopting the method, the quality of the main components including the Chinese ephedra and the platycodon root, which cause problems easily, in a prescription is effectively controlled, so that the quality of the wind-cold cold granules is better and more comprehensively reflected, fake and shoddy wind-cold cold granules produced by illegal manufacturers can be effectively detected and identified, and then the safety and effectiveness of mass medication are ensured.

The invention discloses a quality detection method of a Chinese traditional patent medicine fallopia multiflora (thunb.) harald-aloe constipation relieving capsules for treating constipation. According to the quality detection method, the ginseng, the citrus aurantium, the aloe and the donkey-hide gelatin in the preparation are identified through a thin layer chromatography method while the 2,3,5,4'-tetrahydroxyl diphenylethylene-2-O-beta-D-glucoside content of the fallopia multiflora (thunb.) herald and the naringin content of the citrus aurantium in the preparation are determined by using HPLC. According to the present invention, the quality detection method has characteristics of stability, reliability, strong specificity and good reproducibility; and with the method, the quality of the fallopia multiflora (thunb.) harald-aloe constipation relieving capsules can be completely and effectively controlled, the stability of the product quality is easily achieved, the clinical medication safety and effectiveness can be ensured, and the medical and market needs can be well met.

The invention provides a detection method for compound Dan Yin paste. The method includes identification on characters and components, inspection, and content measurement. The invention aims to incomplete detection standards of the compound Dan Yin paste in the prior art, in which there are no any quality detection measures besides detections on common indices according to preparation general rules, so that the detection methods, in the prior art, has defects of monitoring medicine quality. In the method, the following items are added: identification between capillary artemisia and artemisia apiacea, identification between salvia miltiorrhiza and gentiana macrophylla, identification on radix bupleuri and licorice roots, content measurement of tanshinone IIA, and content measurement of salvianolic acid B. The method can effectively detect whether the corresponding medicine raw materials are less than standard contents or are not added due to lawless enterprises or not, and also can detect adulteration of the artemisia apiacea and gentiana macrophylla, which are liable to be confused, thereby preventing mis-use. The method can effectively guarantee the quality of the compound Dan Yin paste, ensures that the compound Dan Yin paste to be safe and effective, can guarantees clinical curative effects of the medicine and protects patient benefits.

The invention discloses a dried noodle smoothness detection device which is favorable for objectively evaluating the quality of the dried noodle. The detection device is characterized by comprising a base (2), wherein a fixing bracket (18), a noodle clamping mechanism and a power device (17) are arranged on the base (2); a lifting arm (12) is arranged on the fixing bracket (18) and can perpendicularly move under the action of the power device (17); and an upper clamp (10) connected with a mechanic sensor (11) is arranged on the lifting arm (12) and is positioned above the noodle clamping mechanism.

The detection device has the advantages of simple structure, convenience in operation, and scientific and reasonable detection method; and in addition, the dried noodle smoothness can be accurately reflected through the friction resistance, which is favorable for objectively evaluating the quality of the dried noodle.

The invention discloses a quality detection device for a door / window screen, belonging to the field of quality detection. The quality detection device disclosed by the invention comprises an overall frame, a screen clamping mechanism, a detection mechanism and a loading mechanism, wherein the screen clamping mechanism adjusts the relative height of a screen fixing rod on the overall frame by utilizing a tensioning mechanism; a screen fixing clamping groove is formed in the overall frame, and the upper and lower sides of a to-be-detected screen are clamped by virtue of the screen fixing clamping groove and the screen fixing rod; the detection mechanism comprises a driving motor, a lead screw sliding table, a support frame, a detection meter bracket, a digital indicator and a sliding rail; the lead screw sliding table is driven by the driving motor and is used for driving the support frame to move along the horizontal direction; a measuring head of the digital indicator faces the to-be-detected screen, and the digital indicator is positioned in the middle of the to-be-detected screen; and the loading mechanism hooks the to-be-detected screen by virtue of a hook so as to realize tension loading of the to-be-detected screen. The special detection device and method are designed according to the screen detection standard, the structure is simple, the detection is convenient, and the intelligent degree is high.

The invention relates to a concrete pole rebar quality tester and a detection method by using the tester. The tester is composed of a fixed stand, an exciter, a rotary encoder, a cell box, a signal preprocessor, an ARM (analog digital conversion) processor, a magnet measuring element and the like, wherein the fixed stand can be sheathed on a concrete pole to be tested, and the magnet measuring element and the exciter are installed together. When the concrete pole rebar quality tester is used for detection, the fixed stand is tightly sheathed on the concrete pole to be tested; the clip of the cell box is clamped on the belt of an inspector; the exciter magnetizes the rebar to generate back magnetic flux; the magnet measuring element measures the back magnetic flux passing through an armature; and the back magnetic flux is relevant to the diameter, the amount, the position, the corrosion and the like of the rebar, i.e. the back magnetic flux is converted into an electrical signal, is amplified, filtered and the like by the signal preprocessor, is subjected to analog digital conversion by the ARM processor and is analyzed to obtain a parameter which needs to be detected. The tester disclosed by the invention is simple to manufacture and is convenient to operate, the rebar in the concrete pole can be detected, the diameter, the position, the amount and the corrosion degree of the rebar can be accurately judged, and the detection method is scientific and reasonable.
