The invention discloses a liver cancer metastasis therapeutic device, which is composed of a base plate, a prone support, a belly medicine massager, a chain wheel, a rotating wheel and a handheld massager, and used for recovering functions of a whole body. As shown in Schematic Diagram of Liver Cancer Metastasis Generation and Development Principle, Schematic Diagram of Liver Cancer Metastasis Therapeutic Principle and Technology, and Schematic Diagram of Death Causes and Death Process Change Rules of Patients with Liver Cancer Metastasis in a specification, in the focus generation period of cancerometastasis, cancer cells are killed mainly for eliminating metastasis focuses, attenuating symptom and delaying development of the focuses; in the death period of cancerometastasis, the functions of the whole body are recovered mainly for controlling development trend of the lesion and preventing death; functional lesion of the whole human body is the main factor for death, and systematic cancerometastasis focuses are secondary factors for death. The liver cancer metastasis therapeutic device is focused on recovering the functions of the whole human body with supplement of performing surgery and chemoradiotherapy for killing cancer cells to perform therapy aiming at causes of death, and thereby the target of significantly reducing a death rate of patients with metastasis of liver cancers and digestive organ cancers is achieved.

The invention provides a data-driven water surface reconstruction method and system, and relates to the field of image processing and computer vision. The method comprises the steps of acquiring a water surface video, and parsing the water surface video into a single-frame image according to a frame rate of the water surface video; dividing the image into blocks, calculating the reflectivity of the water surface in each block, calculating information entropy of each block based on the reflectivity thereof according to each reflectivity, setting a threshold, when the information is less than the threshold, subdividing the block corresponding to the information entropy less than the threshold into new blocks, calculating the information entropy of each new block until the information entropy of each new block is greater than the threshold, and acquiring the height field of each block; and seaming the height fields of the blocks into a whole.

The invention belongs to the design technology of marine oil and gas equipment, and in particular relates to a fatigue design method of a deepwater riser. This method considers the coupling effect of the vortex-induced motion of the floating platform and the vortex-induced vibration of the riser when calculating the fatigue damage of the deep-water riser. The influence of the fatigue damage caused by the vortex induced motion of the floating platform caused by the current on the fatigue damage of the riser is considered, and the influence of the fatigue damage caused by the extreme wave load on the fatigue damage of the riser is considered. The present invention is more in line with the actual fatigue damage accumulation essence of the deepwater riser, more in line with the known Miner's linear damage accumulation criterion, more in line with the current environmental load change trend and characteristics, more scientific and reasonable, and the design result is safer and more reliable.

The invention discloses a method for producing β-mannanase by using Aspergillus niger, which belongs to the technical field of enzyme engineering. The present invention adopts agricultural and sideline products such as bran, corn flour and rapeseed cake powder as base material, and adds appropriate amount of konjac flour, corn steep liquor, inorganic salt and tap water etc., utilizes Aspergillus niger (Aspergillus niger) WA9024 bacterial strain solid-state fermentation to produce Mannanase provides the fermentation medium formula and fermentation conditions for small-scale production and industrial production. The β-mannanase activity of mature fermented koji produced in small-scale production reaches 18912-22185IU / g dry koji, which is higher than that of the original koji WA9024 strain. The enzyme activity (8984IU / g dry koji) of small-scale production of solid-state fermentation has increased by 2.11-2.47 times, which is higher than the current domestic level; the enzyme activity of industrial production products is 12678-15921IU / g dry koji. The present invention uses cheap bran, corn flour, rapeseed meal and the like as main raw materials for fermentation, is a kind of fully utilizing natural renewable resources, and is also a green and sustainable production method.

The hollow concrete block for protecting perennial frozen soil road bed and slope consists of plant stalks, cement, sand and soil, and is hollow cube with outer side length of 30-200 mm and wall thickness of 10-50 mm. It may be also hollow sphere, hollow cuboid or hollow cylinder. The present invention is simple in construction, low in cost, easy in maintenance, and has the merits of both sun shield and ballast revetment. Hollow blocks of different shapes are combined in certain thickness to reach excellent sun shielding effect and excellent ventilation and temperature lowering effect for protecting perennial frozen soil road bed and slope positively.
