The catalyst provided by the present invention also has the advantages of simple preparation method, safe and feasible preparation process, good large-scale preparation activity, and large specific surface area (up to 154m 2 / g) and excellent spatial structure. The catalyst provided by the invention can prepare high-quality carbon nanotubes, the I_G / I_D can reach 17, the average diameter is 8.7nm, and the carbon content of the crude product of the carbon nanotubes exceeds 92%.

Embodiments of the present application disclose a honeycomb carrier plate for in-vitro culture of hepatocytes and a bioreactor for an artificial liver, and aim to solve the problems of insufficient space for agglomeration growth of extracorporeal hepatocytes and low substance exchange efficiency in a bioartificial liver. According to the honeycomb carrier plate for the in-vitro culture of the hepatocytes provided by the embodiments of the present application, honeycomb holes in the honeycomb carrier plate are divided into first honeycomb holes and second honeycomb holes, the first honeycomb holes are opened at the top ends and closed at the bottom ends, and are used for accommodating the hepatocytes, and the second honeycomb holes are closed or opened at the top ends and opened at the bottom ends; and the honeycomb wall of each honeycomb hole is provided with a first through hole with a pore diameter smaller than the diameter of each hepatocyte, the closed ends of the first honeycomb holes and the second honeycomb holes are provided with second through holes with a pore diameter smaller than the diameter of each hepatocyte, each second honeycomb hole is arranged in same edges withsix first honeycomb holes adjacent to the second honeycomb hole, and each first honeycomb hole is arranged in same edges with three alternately-distributed first honeycomb holes adjacent to the firsthoneycomb hole and three alternately-distributed second honeycomb holes adjacent to the first honeycomb hole. The internal structure of the bioreactor is formed by vertically stacking honeycomb carrier plates and air-permeable hollow fiber membrane tubes layer by layer.

The invention discloses a floating algae reef for marine ranch construction, which consists of a hollow rod body and corner pieces to form a frame connected to the net body, the frame body is connected to the float through a float rope, and the anchor is connected through a cable; the frame body is connected through the middle A hollow rod body is set in the middle of the frame body; both ends of the hollow rod body are blocked by corner connectors or corner connectors and middle connectors, and a rectangular through hole is processed at the middle of the hollow rod body, and the hollow in the middle of the rectangular through hole The rod body is provided with a fixed part, the fixed part is provided with a guide rod coaxial with the hollow rod body, and the guide rod is slidably connected with an adjusting plug body; the rectangular through hole at the middle of the hollow rod body passes through the upper cover body, the lower The cover body and the sealing ring body are closed. The invention can realize the scalability of the floating algae reef and the adjustability of the vertical height after being placed, so that the macroalgae attached to it have a larger attachment area, better light receiving property and depth, and can promote large-scale growth of algae etc.

The invention discloses a combination box for early-maturing and high-efficiency cultivation of melons, which comprises a support plate, a cultivation box and a combination bracket. A support column is fixedly connected to the center of the upper surface of the support plate, and a cultivation box is movably connected to the support column. The support plate The lower surface of the cultivation box is symmetrically connected with universal wheels, and the center position of the lower surface of the cultivation box is fixed with a lifting rod. The combination box for early-maturing and high-efficiency cultivation of melons is composed of a combination of multiple cultivation boxes. Provide support for the climbing of melon vines. After the first support rod and the second support rod are fully stretched, they can automatically press the raised column to realize the loosening of the lifting rod and the support column, so that the cultivation box can be moved down as a whole, which is convenient for adjustment .

The embodiment of this application discloses a biological artificial liver purification circulation unit and artificial liver support system. Biological conversion and synthesis function, give full play to the purification advantages of various means. The bioartificial liver purification circulation unit provided in the embodiment of the present application includes a plasma storage bag, a pipeline warmer, a plasma circulation pump, a high-flux filter, a neutral resin adsorber, Dissolved oxygen-pH monitors and bioreactors.

The present invention relates to the technical field of sweet potato planting, and provides a seedling-strengthening composition for cultivating sweet potato seedlings, comprising a seedling-strengthening solution 1 and a seedling-strengthening solution 2, and the seedling-strengthening solution 1 includes 2-20 ppm of furan nucleotides and No. 5 rooting powder 50-180ppm and thiophanate-methyl 1000-1600ppm; the strong seedling solution 2 includes 2-20ppm furan nucleotides, 2200-3600ppm potassium dihydrogen phosphate and 350-700ppm spirotetramat. Strong seedling solution 1 is applied after the seed potatoes are sealed with soil and watered, which can promote the germination of seed potatoes, inhibit viruses, and kill bacteria and fungi; The growth status of seedlings, the inhibition of viruses, and the prevention and treatment of whitefly and other diseases and insect pests. Compared with the conventional method, the sweet potato seedlings cultivated by adopting the strong seedling composition of the invention are stronger, and the sweet potato yield of the obtained sweet potato seedlings is increased by more than 12% compared with the conventional method.

The invention provides a method for implanting and cultivating Gracilaria bursa-pastoris in a north pond. By using the method, the problems of water eutrophication and the like, caused by the ecological imbalance owning to using the prior art for signal animal breeding in the north pond, can be solved. The cultivation process of the invention can be divided to a sprout proliferation phase, a bottom sowing propagation phase, an increasing interharvesting phase and an overwintering seedling protection phase. By using the invention, the problem that owning to the change of factors such as climate, growing environment and the like in the north, the transplanting of south macrophyte fails, can be solved; the method has effects of low input and high output, and the ratio of the fresh weight input to fresh weight output of the algae is 1:1500. The yield per mu is 1500kg. The method of the invention can be used to fill the gap of cultivating macrophyte in aestival pond of northern areas and the diversity of algae resources in northern China is enriched.
