The performances and durability of a diaphragm sheet of a solar cell laminator are enhanced, and a favorable lamination work is stably performed over a long period of time. In addition, by stably performing sufficient and uniform lamination over a long period of time, a high-quality module is stably manufactured over a long period of time.A solar cell module is manufactured by using a diaphragm sheet formed of a composition containing an ethylene-propylene-diene rubber (EPDM), which is low in creep deformation and high in durability against an organic peroxide and a silane coupling agent.

The invention relates to the use of a thermal insulating layer for a housing of a steam turbine in order to even out the deformation behaviour of different components based on different heatings of the components.

The invention provides a prestressed unbonded anchor rod steel bar. The prestressed unbonded anchor rod steel bar comprises a main steel bar body serving as a basic force bearing structure, the main steel bar body is a finish rolling steel bar or a common steel bar, an anti-corrosion grease layer is arranged on the surface of the main steel bar body, and a plastic film sleeve is arranged outside the anti-corrosion grease layer. The number of the main steel bar bodies is one or one to five, and the main steel bar body is of a main steel bar structure formed by connecting segmented reinforcing steel bars through connecting nuts. According to the prestressed anchor rod prepared from the unbonded anchor rod steel bars, the unbonded main steel bars are directly cast into the prestressed anchorrod through concrete, or the lower end of the prestressed anchor rod is connected with grouting bodies or concrete of expanded heads; the grouting body or concrete of the expanded head is internally wrapped with a steel reinforcement framework or a bag, wherein the steel reinforcement framework comprises one or more steel reinforcements, a steel reinforcement cage with a common structure and a variable-diameter steel reinforcement cage; an anti-floating tensile anchor rod of a concrete prefabricated pipe column is prepared when a steel reinforcement cage and a variable-diameter steel reinforcement cage of a common structure are adopted; one or more reinforcing steel bars are connected by using one or more reinforcing steel bar anchor rod reinforcing steel bars; and one or more reinforcingsteel bars or reinforcement cages are still arranged in the center of the bag.

The invention discloses a gas turbine engine with a transition duct and a corresponding method of manufacturing a transition duct. The gas turbine engine (10) having a combustor (16), a turbine (18) and a transition duct (17), the transition duct (17) is located between the combustor (16) and the turbine (18) to channel hot gas (34) from the combustor (16) to the turbine (18). The transition duct (17) has an internal surface (54, 55, 56, 57) on which the hot gas (34) impinges to cause a varying temperature profile over the internal surface (54, 55, 56, 57). A thermal barrier coating (100) is located on the internal surface (54, 55, 56, 57) and comprises at least a first thermal barrier coating patch (72P) and a second thermal barrier coating patch (74P). The first thermal barrier coating patch (72P) having a first predetermined thickness (72T) located on the internal surface (54, 55, 56, 57) and within a first area (72A) subject to a higher temperature than an uncoated part of the internal surface (54, 55, 56, 57) and bounded by a first isotherm (73) of a first predetermined temperature. The second thermal barrier coating patch (74P) having a second predetermined thickness (74T) located on the internal surface (54, 55, 56, 57) and within a second area (74A) subject to a higher temperature than the uncoated part of the internal surface (54, 55, 56, 57) and bounded by a second isotherm (75) of a second predetermined temperature. The second predetermined temperature is higher than the first predetermined temperature and the second predetermined thickness (74T) is thicker than the first predetermined thickness (72T). A corresponding method of manufacturing a transition duct is also provided.

The invention discloses a method of a beside-pillar double-side total-filling ascending re-mining overhead coal seam. In the invention, on the basis of determining overhead coal seam mining feasibility and detecting distribution situations of a coal pillar group and a mined area group of a reamer-pillar remnant mining area, a beside-pillar double-side total-filling method is employed for successively side-protecting the coal pillar group in the underlie reamer-pillar remnant mining area of the overhead coal seam and gradually mining the overhead coal resources. By means of the method, a beside-pillar double-side filling body formed in the mined area group can not only achieve a side-protecting effect on the reamer-pillar coal pillar group but also form a common bearing body therewith, thereby further reducing degree of stress concentration and creep deformation of the coal pillar group. The method can enhance long-term stability, can avoid local instantaneous unstability or domino-like unstable damage and finally can ensure safe mining of the overhead coal seam of the reamer-pillar remnant mining area.
