摘要： A system and a method for calibrating a distributed optical fiber for health perception of a water-adjacent building, comprising a heat insulation barrel, and a plurality of calibration modules located in the heat insulation barrel around the axis thereof. Each calibration module comprises a through shaft (313), a first electronic thermometer (341) and a second electronic thermometer (345). The through shaft (313) is wound with an optical cable to be calibrated (348). The optical cable to be calibrated (348) is connected to an optical fiber temperature demodulator outside the heat insulation barrel. The first electronic thermometer (341) and the second electronic thermometer (345) are connected to a first temperature control meter (306) and a second temperature control meter (308) outside the heat insulation barrel, respectively. A temperature source heat wire (353) for heating water in the heat insulation barrel is disposed in a barrel wall of the heat insulation barrel.

摘要： Disclosed is a preparation method for a sulfonated two-dimensional titanium carbide nanosheet. The method comprises the following steps: preparing two-dimensional titanium carbide by removing the aluminum atomic layer from lamellar titanium aluminum carbide by chemical exfoliation using hydrofluoric acid; preparing sulfanilic acid diazonium salt; and preparing a sulfonated two-dimensional titanium carbide nanosheet by sulfonation reaction of the two-dimensional titanium carbide and the sulfanilic acid diazonium salt. The sulfonated two-dimensional titanium carbide nano material prepared by the present invention has good dispersibility in water and common organic solvents, and a single-layer or few-layer sulfonated two-dimensional titanium carbide nanosheet with a large size and high quality can be obtained by performing ultrasonic treatment on the dispersion solution. The preparation method has the advantages of low production costs, readily available raw materials, and simple and controllable preparation process.

摘要： A desalination method for improving topsoil of a saline-alkali land by using silt is disclosed. The method includes the following steps: (a) mixing topsoil of a saline-alkali land with silt, to form a mixed zone with a permeability coefficient of 1.Ox10-6 cm/s to 5.Ox1 0-5 cm/s; (b) building ridges around the mixed zone using silt, irrigating the mixed zone with fresh water for 2 to 4 months, and keeping a water depth of between 10 cm and 15 cm; and (c) planting rice in the mixed zone, and draining and irrigating the rice according to the growth characteristics and needs of the rice. Through mixing of topsoil of a saline-alkali land and silt, a mixed zone with a certain permeability coefficient is formed. In this way, a structure of the topsoil of the saline-alkali land can be improved, the soil fertility is improved, suitable conditions for the growth of rice are created, and a yield of the rice is improved. Moreover, after the structure of the topsoil of the saline-alkali land is improved by mixing with the silt, a permeability coefficient of the topsoil is decreased, and a permeation rate of a fresh water-containing soil layer is decreased, so that less fresh water can be used to maintain continuous downward permeation of fresh water, achieving salt-leaching and salt-reducing effects.

摘要： A preparation method for a high-density hexagonal boron nitride (hBN) ceramic material. The method adopts ethyl orthosilicate as a raw material to coat a uniformly dispersed SiO2 nano-particle layer onto the surface of an hBN powder, then obtains the high-density hBN ceramic material by adopting a pressureless sintering method, wherein the relative density of the prepared hBN ceramic material reaches not less than 80%. The method achieves the uniform dispersion of the SiO2 sintering aid by coating SiO2 onto the surface of the hBN powder, obtains the high-density hBN ceramic in combination with high-temperature pressureless sintering, and improves the high-temperature operating temperature and high-temperature properties of the hBN while reducing the usage amount of SiO2.
