The invention discloses a double-person heat-preserving quilt. The double-person heat-preserving quilt comprises a quilt main body, a heat-preserving module and a wind-proof skirt, wherein the heat-preserving module is connected with the upper end of the quilt main body through a button; the wind-proof skirt is positioned on the edge of a concave arc-shaped structure of the heat-preserving module. The double-person heat-preserving quilt can play roles in resisting wind and preserving heat for the neck and shoulders of a user; in particular, when two persons lie on the side, good wind-resisting and heat-preserving effects can be well achieved.

The invention discloses a novel X-shaped rack culture technology for kiwi fruits. According to the novel technology, planting is carried out in large and small rows, multiple X-shaped racks are erected in the row direction of the small rows, and every two adjacent X-shaped racks are connected with one another by iron wires in the row direction; the iron wires include the upper traction iron wires,the lower traction iron wires and the supporting iron wires, and traction ropes are connected between the upper traction iron wires and the lower traction iron wires; fruiting branches obtained in the current year are put on the two supporting iron wires; culturing branches are subjected to traction fixation on the traction ropes; the culturing branches are pruned and removed from the racks in autumn, the pruned culturing branches and the fruiting branches reserved for the next year are laid flat on the ground in the same direction and stretch into ditches, and then the branches above are covered with soil and felt for cold prevention. The operation is simple, strength is saved, efficacy can be achieved quickly, and high yield can be achieved next year; popularization is easy, and the branches are covered with soil after being removed from the racks for cold prevention and thus are not afraid of coldness. The planting density can be reasonably increased, the environmental conditions are improved, and therefore the yield of the kiwi fruits is increased. Meanwhile, a cold prevention problem is solved, and high yield of the kiwi fruits in the north can be achieved quickly.

The invention discloses a steam heating pipeline for cold protection for the top of exhaust masts of an LNG carrier in ice regions. The steam heating pipeline comprises pre-insulating pipes fixed to the outer wall of the exhaust masts through BHT pipe clamps, steam heating main pipes led from a marine daily steam pipeline, downspouts fixed at the bottom of funnel devices fixed inside exhaust capsand condensing pipes integrated in the pre-insulating pipes after running through the downspouts, wherein the steam heating main pipes are wrapped in the pre-insulating pipes; two heating branch pipesextend from the top of each steam heating main pipe; the heating branch pipes are laid along the inner wall of the exhaust caps to exhaust grilles at the top of the exhaust caps; and the heating branch pipes are laid from the exhaust grilles to the inner wall of the funnel devices. The steam heating pipeline for the cold protection for the top of the exhaust masts of the LNG carrier in the ice regions can prevent the exhaust caps at the top of the exhaust masts from being frozen by using the scheme of steam heating for the cold protection in the ice regions on the basis of not changing the prior structure of the exhaust masts, thereby enabling the exhaust masts to meet the requirement of cold protection in the ice regions, ensuring the safety of the LNG carrier and solving the problem ofcold protection in the ice regions.
