The present discloses relates to a method for continuously synthesizing 5-hydroxymethylfurfural by using a micro-channel reactor, which belongs to the technical field of micro-chemical engineering. The method includes: separately conveying an aqueous glucose solution, which contains FeCland HCl, and methyl butyl ketone to a T-shaped micro-mixer, the T-shaped micro-mixer being in communication with a capillary tube; then enabling an aqueous glucose solution phase and a methyl butyl ketone phase to flow in the capillary tube in a segmented flow manner while performing an HMF synthesis reaction; and collecting a reaction product flowing out of the capillary tube, wherein HMF generated by the reaction is present in an organic phase of the reaction product. The method is easy to operate, has a controllable process, high product yield, a low by-product amount and a short synthesis period, and is a green method for efficient and continuous synthesis of HMF.

In a system for intelligent monitoring strain and temperature of a bullet tank, distributed strain fiber optic cables and distributed temperature fiber optic cables are laid on a surface of a bullet tank body, and pressure gauges are arranged in a soil layer below the bullet tank body, so that the surface and surrounding states of the bullet tank body are monitored. Detected data is gathered by collectors and then transmitted to a field control system. The field control system respectively performs data communication with a numerical simulation system and a central control display screen. The numerical simulation system uses finite element software to simulate the bullet tank body and the soil layer below, determines a corresponding temperature and stress change range, and transmits the temperature and stress change range to the field control system for comparison with the detected data.
