Abstract: A phase diagnosis method and apparatus. When it is verified that the location of an engine is valid, an oil injector performs spraying at a top center compression position; if no acceleration is detected after spraying, it indicates that a fault occurs; in order to detect whether it is a fault of phase deviation of the camshaft by 180 degrees, the oil sprayer performs spraying at the top center exhaust position and detects whether there is an acceleration; if an acceleration is detected, it indicates that the situation of the phase deviation of the camshaft by 180 degrees exists. In this way, the problem in the prior art of being unable to detect phase deviation when the phase of a camshaft is deviated by 180 degrees is solved.

Abstract: A 99mTc-labeled isonitrile-containing glucose derivative having the general formula [99mTc-(CNDG)6]+, preparation method and use thereof is disclosed herein. The derivative is centered on 99mTc+, and the carbon atom of the isonitrile in CNDG coordinates with 99mTc(I) to form a hexacoordinated complex [99mTc-(CNDG)6]+. The [99mTc-(CNDG)6]+ derivative was obtained by the synthesis of the ligand CNDG and the preparation of the lyophilized CNDG kit. The derivative of the present invention this disclosure has good stability, simple preparation, high uptake and good retention at a tumor site, and high tumor/non-target ratio, and it is a novel 99mTc-labeled isonitrile-containing glucose derivative with excellent performance for tumor imaging. The derivative of the present invention this disclosure is advantageous for popularization and application.

Abstract: A fast blind plate switching device is provided, including a sealing structure, a clamping structure, a support structure and an execution mechanism. The blind plate has an open-state and a blind-state. The support structure is used for connecting pipelines at two sides and providing support for the whole device. The clamping structure and the sealing structure are located inside the support structure. The clamping structure is driven by the execution mechanism, and under the drive of the execution mechanism, the clamping structure presses on the blind plate to eliminate a gap between two sides of the blind plate, so that sealing is formed by means of the sealing structure. When a gap is formed away from the blind plate, the open/state and the blind state of the blind plate is switched.
