The invention relates to an improved test device for testing an oxidizing solid. The improved test device is provided with a test system and a measurement system and is characterized in that the test system and the measurement system are positioned at two ends of a lever system and are connected with each other through the lever system; the test system comprises a bracket A, a limiting block, a tray A, a heat isolation plate, a wiring post and a resistance wire; the lever system comprises a lever, a wire A, a wire B, an electric brush, a current collection ring, a bracket B and a power supply; the measurement system comprises a balance weight, a tray B, a level adjuster and a balancer. Compared with the prior art, the improved test device disclosed by the invention has the advantages that the test system can be separated from the measurement system, the measurement precision is improved according to an equal arm lever principle, and damage of heat and dust on the balancer during combustion can be eliminated.

The invention discloses an intelligent laser range finder control system, which relates to the technical field of laser range finders, and includes a pulse output module, a data acquisition module, a signal verification module and a loss analysis module; the pulse output module is used to output electric pulses to Drive the radio band frequency of the modulator to the target frequency; the data acquisition module is used to collect the radio band frequency of the modulator, and transmit the collected frequency to the data analysis module for validity analysis, and calculate the current band frequency in conjunction with the target frequency Deviation coefficient, judging whether it is necessary to fine-tune the radio band frequency of the modulator to ensure the accuracy requirements of the radio band frequency for amplitude modulation of the laser beam; the signal verification module is used to verify the communication status of the laser rangefinder in real time, according to the communication The bias value judges whether the communication status of the laser rangefinder is normal, prompts the user to deal with it in time, and effectively improves the measurement accuracy and accuracy of the laser rangefinder.

The invention discloses an online bladder pressure measurement method and system, and relates to the field of medical equipment monitoring. The pressure measurement system includes a base, a first guide rod, a heating box and a disinfection box. An adjustment rod is slidably installed on the first guide rod. A top plate is provided on the top of the adjustment rod, and an infusion set is connected to one side of the bottom of the top plate. There is an infusion tube, and the heating box is set next to the infusion set to heat the physiological saline in the infusion tube. The other side of the bottom of the top plate is fixed with a scale and a transparent sleeve with a pressure measuring tube; there are double chambers running through the disinfection box Urinary catheter, the Y-shaped end of the double-lumen catheter is connected with the infusion tube and the pressure measurement tube respectively, and the top of the infusion tube and the pressure measurement tube penetrates and is fixed on the top cover of the disinfection box; observe the water column in the pressure measurement tube during the test According to the height, the data obtained according to the scale beside it is the pressure in the bladder. Using the device of the invention can avoid bacterial infection, ensure the sterility of joints, and prevent the bladder from being affected by too low temperature of saline water to affect measurement.

The invention provides a body length measurement device for experimental animal rat physiological state, comprising a preparation chamber, a body length measurement channel, a platform and an image recording device; the platform has an inclined surface, and the body length measurement channel is obliquely arranged on the side of the platform On an inclined surface; the bottom end of the body length measurement channel is an inlet, and the top is an outlet; the outlet of the preparation warehouse is connected to the inlet of the body length measurement channel; scales are arranged on the bottom surface of the body length measurement channel; the body length The channel side walls on both sides of the measurement channel can move to both sides along the direction perpendicular to the body length measurement channel; the image recording device is used to take and record the images of experimental animals and rats in the body length measurement channel. The device of the invention can realize accurate and non-invasive measurement of the body length of experimental animals.
