Abstract: A method for determining a consistency coefficient of a power-law cement grout includes: determining a water-cement ratio of the power-law cement grout; according to engineering practice requirements, determining a time required to determine the consistency coefficient of the power-law cement grout; and obtaining the consistency coefficient of the power-law cement grout. The method is accurate and reliable, requires less calculation, etc.; and has very high practical value and popularization value in environmental protection and ecological restoration.

Abstract: A package structure and a manufacturing method thereof are disclosed. The package structure includes: a substrate; at least one light emitting diode disposed on the substrate by eutectic bonding; and at least one Zener diode disposed on the substrate by at least one silver glue. The method of manufacturing the package structure includes: providing a substrate; performing a eutectic bonding process to dispose at least one light emitting diode on the substrate; and performing a silver glue bonding process at room temperature to dispose at least one Zener diode on the substrate.
