The invention discloses an isolating net piece and a carrier vehicle for loading the isolating net pieces. The isolating net piece comprises an isolating net piece body, a support and an isolating barrier, wherein the isolating net piece body comprises a framework and a net piece arranged on the framework, the support comprises a regulating lever and regulating lever landing legs, is arranged at one side of the isolating net piece body, and is used for supporting the obliquely placed isolating net piece body and regulating the length of the regulating lever according to needs, and the isolating barrier inclining towards the same side is formed by serially connecting a plurality of isolating net piece bodies. The compartment body of the carrier vehicle is formed by a plurality of tank bodies, one isolating net piece is placed in each tank body, the isolating barrier formed by serially connecting the isolating net piece bodies is not easy to damage or incline, can prevent people from climbing and crossing and has a very good blocking effect, handling of the isolating net pieces is convenient and labor-saving, and since the carrier vehicle for loading the isolating net pieces is specially designed, loading of the isolating net pieces is fast, and the transportation process is safe and reliable.

The invention provides a guided missile mass and mass center adjusting device and method. The guided missile mass and mass center adjusting device comprises balance weight pipes (2, 3) located in a guided missile bin (1), a plurality of clump weights (4) placed in the balance weight pipes (2, 3), and end caps (5, 7, 8, 9) detachably connected with the two ends of the balance weight pipes (2, 3) correspondingly; and the balance weight pipes (2, 3) are connected with the guided missile bin through flange plates (6, 10, 11). During assembling of the guided missile mass and mass center adjusting device, firstly, the end caps at one end are connected with a bin body or one flange plate (10), and then one ends of the balance weight pipes are connected with the end caps; then the other ends of the balance weight pipes are fixed through the other flange plates (6, 11), the end caps at the other ends of the balance weight pipes are assembled, and the bin body without balance weight is assembled; and after installing and debugging of equipment in the bin are completed, the initial values of the mass and the mass center of a guided missile are measured, the balance weight scheme is formulatedthrough comparison with the theoretic mass and mass center, and accurate adjusting on the mass and the mass center is achieved.

The invention provides a one-time cutting forming machining production system of a building plate. A shape trimming device can conduct shape trimming on the building plate so that the building plate can enter a cutting portion at the standard position and in the standard direction, a clamping groove cutting device conducts clamping groove cutting, a clamping strip cutting device conducts clampingstrip cutting, and then the building plate is separated and divided by a separation cutting device into a plurality of independent single building plate bodies, wherein each single building plate bodycomprises clamping grooves and clamping strips and has a splicing and assembling function. In addition, clamping groove saw sets and clamping strip saw sets can be randomly assembled and arranged toform different thicknesses and different cross-section shapes through clamping groove saw blades and clamping strip saw blades, and then the clamping grooves with different sizes and shapes and the clamping strips with different sizes and shapes are cut. As a result, by the adoption of the one-time cutting forming machining production system of the building plate, the building plate which comprises the clamping grooves and the clamping strips and has the splicing function is formed through cutting at one time, parameters such as the sizes and the shapes of the clamping grooves and the clampingstrips can be changed at will, and the one-time cutting forming machining production system of the building plate is simple in working procedure, high in efficiency, good in cutting quality, flexibleand convenient to use, novel and reasonable in structure and high in practicability.

The invention discloses an in-situ test device of high-pressure and low-temperature heat conductivity coefficients and heat transfer coefficients. The in-situ test device comprises a high-pressure and low-temperature reaction kettle, a thermistor measurement probe, a power supply input control system and a data acquisition system, wherein a thermistor and a control circuit board are arranged in the measurement probe; the measurement probe is sealed by virtue of a high-pressure seal ring; a side resistor and a circuit protection device are arranged on the circuit board; a connecting lead with an insulating paint coating passes through a fine stainless steel tube, then passes through a high-pressure seal device, and is pressed and sealed by pressure-proof plastic; the fine stainless steel tube is spliced and fixed to the seal device by using epoxy resin; holes are uniformly formed in the fine stainless steel tube; two chambers of the high-pressure and low-temperature reaction kettles are connected with each other by virtue of a piston; and a measured sample is directly put into the upper chamber of the high-pressure and low-temperature reaction kettle. The piston is pushed by injecting liquid into the lower end of the high-pressure and low-temperature reaction kettle through a constant pressure pump, so that the measured sample in the chamber is pressed in a standardizing manner; the in-situ test device can meet the requirements of in-situ synthesis of different mediums under high pressure and at low temperature and can be used for carrying out in-situ measurement on the heat conductivity coefficients and the heat transfer coefficients of multi-phase substances in different spaces and different time.

The invention relates to a cooling control method for bearing steel balls. The bearing steel balls are immediately put into a normalizing liquid in a cooling pool to be cooled after being forged, theconcentration and temperature of the normalizing liquid are controlled, and the marching speed of chain plates used for conveying the bearing steel balls is adjusted simultaneously; and the bearing steel balls are cooled at the cooling speed of 2.5 DEG C / S to 3 DEG C / S, the temperature of the bearing steel balls is monitored, the normalizing liquid is lifted out when the bearing steel balls are cooled to 600 DEG C to 750 DEG C, and the bearing steel balls are cooled through sprays. According to the cooling control method for the bearing steel balls, the tempering-resisting stability of products is significantly improved, impact toughness is greatly improved, and the contact fatigue life is greatly prolonged; and meanwhile, the uniformity and consistency of internal structures of the products are improved, and the level of network carbides can be controlled to be below level 2.
