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: The present disclosure describes a method for forming metallization layers that include a ruthenium metal liner and a cobalt metal fill. The method includes depositing a first dielectric on a substrate having a gate structure and source/drain (S/D) structures, forming an opening in the first dielectric to expose the S/D structures, and depositing a ruthenium metal on bottom and sidewall surfaces of the opening. The method further includes depositing a cobalt metal on the ruthenium metal to fill the opening, reflowing the cobalt metal, and planarizing the cobalt and ruthenium metals to form S/D conductive structures with a top surface coplanar with a top surface of the first dielectric.

Abstract: A convex mirror formed of a back board, a mirror, a ball head connecting rod, a ball socket, a socket cover and a mounting frame is disclosed. The back board has stub rods and retaining holes for receiving respective locating holes and hollow cylindrical posts of the ball socket to facilitate installation of rivets in affixing the ball socket and the back board together. The mirror has a rim inserted in between a rim and equiangularly spaced locating blocks of the back board to facilitate installation of self-tapping screws in affixing the rim of the back board and the rim of the mirror together.

Abstract: A non-backboard reflector mirror includes a mirror body with a rim, a locating bar affixed to the back side of the rim of the mirror body, a locating frame, which has a clamping portion coupled to the locating bar and movable along and rotatable relative to the locating bar and affixed thereto at the desired elevation and angle, and a mounting frame selectively fastened to an array of mounting through holes at the locating frame at the desired angle for installation in a ceiling, overhead wall, or vertical wall, short wall. An alternate mounting frame may be used for installation in a post so that the non-backboard reflector mirror is used as a traffic mirror.

Abstract: A reflecting mirror fabrication method, which includes the steps of (a) stamping a steel plate into a back panel, which has a rib-reinforced base, a rim extending around the rib-reinforced base, (b) installing nuts in the back side of the back panel for mounting, (c) stamping a steel plate into a mirror, which has a rounded base, a rim extending around the rounded base, and an annular connected between the rounded base and the rim, and (d) roller ramming the rim of the back panel into a scrolled holding down rim portion to affix the rim of the mirror to the rim of the back panel.

Abstract: A convex lens assembly including a back board holding a convex lens, a mounting frame fastened to a support of a building, a ball socket fastened to the back board, a socket cover fastened to the back board to hold down the ball socket, and a ball head connecting rod having a ball head at one end coupled to the ball socket and a threaded rod at an opposite end fixedly connected to the mounting frame, wherein the back board is integrally molded from impart resisting plastic and mounted around the ball head connecting rod, having an annular groove at a front side near the border which receives a flanged border area of the convex lens, a plurality of locating rods pressed at the flanged border area of the convex lens to hold down the convex lens, a circular mounting hole at the center of its back side which receives the ball socket, and a plurality of locating notches equiangularly spaced around the circular mounting hole; the socket cover has a plurality of threaded locating strips perpendiculary raised from th
