Technicality reliability and practicability for the newly-reformed LSY conveyor have been highly improved.The specification and model of the products have been seriated.
We confirmed the stability and reliability of CE-ECL instrument newly devised by separating and analyzing the mixure solution of tripropyl amine and Pro with it.
The results of the trial were further analyzed, including students' average scores, the difficulty, discriminability for each item, and the validity and reliability for the whole test.
The combined method of speed key point monitoring and speed chart monitoring is advanced to prevent hoist overrolling,significantly improving the safety and reliability of mine hoist operation.
The specific properties of probability about loading effect on tunnel lining structure are analyzed by FEM response surface method,and the structure reliability index is calculated by fractile method.
The interelectrode dielectric adopts the polypropylene film with surface coarsening which is easy to impregnate so as to enhance the reliability of high-capacity capacitor.
