A communication adapter for wall-mounting panel to provide better fastness, easy structure, lower production costs and powerful utility includes a casing comprised of an upper lid and a lower lid, a circuit board in the casing, plug and socket connecting to the circuit board, and locking hole on the lower lid to secure the upper lid to the lower lid with a locking pin; a locking tongue being disposed to the lower lid and a hole on the upper lid to allow pulling the locking tongue.

The invention discloses a leukocyte filter with a soft shell and a manufacturing method of the leukocyte filter. The leukocyte filter with the soft shell comprises two PVC (Polyvinyl Chloride) external membranes and a filter membrane assembly; the filter membrane assembly is arranged between the two PVC external membranes to form an unfiltered liquid cavity and a filtered liquid cavity; the filter membrane assembly comprises a combined filter membrane as well as two PVC internal membrane rings which are respectively arranged at two sides of the combined filter membranes; the internal edges of the PVC internal membrane rings are in sealed connection with the external edge of the combined filter membrane, and meanwhile, the internal membrane rings are in sealed connection with the edges of the PVC external membranes; the unfiltered liquid cavity is provided with an inlet catheter; and the filtered liquid cavity is provided with an outlet catheter and a support tube. According to the leukocyte filter with the soft shell and the manufacturing method of the leukocyte filter, the soft shell material and the filter membrane are adopted, and the binding site has the characteristics of high fusion strength, good flexibility and strong elasticity; the soft shell material and the filter membrane are capable of resisting high temperature and high pressure without breakage during the steam sterilization, and are not broken during the high-speed centrifugal separation of blood, resulting in leakage; and meanwhile, the leukocyte filter with the soft shell has the advantages of simple and attractive appearance and high utilization rate of materials and is easy to realize mass production.

The invention relates to a rich-selenium biological organic fertilizer and a preparation method thereof. The selenium fertilizer is prepared by mainly proportioning, processing and synthesizing 10-30 percent of chelate selenium solution, 10-30 percent of chelate zinc solution, 20-40 percent of chelate iron solution, 10-30 percent of boric acid solution, 1-10 percent of antagonist, 10-30 percent of water and 30-50 percent of chelate selenium. The selenium fertilizer has the activation function of enriching nutrient components and activating enzyme, improves the utilization ratio of a nitrogenelement by 11-15 percent, improves the absorbing conversion ratio of selenium by 20 percent and can increase the yield of rice and lead the organic selenium content in the rice to reach 100-300 microgrammes / kg simultaneously; the produced rice has the characteristics of better quality, , rich selenium, environmental protection, and the like.

The present invention provides a magnesium alloy rare earth compound flux and its production method. Its composition includes (wt%) 40-55% of magnesium chloride, 15-25% of potassium chloride, 12-25% of sodium chloride, 1-6% of calcium chloride, 5-15% of calcium fluoride, 1-8% of barium chloride and 3-10% of rare earth activator. Said ivnention flux has high activity, proper melting point, density, viscosity and surface tension, and can greatly raise mechanical property of magnesium alloy and corrosion resistance.
