13.This series instrument adoption the electric current, electric voltage double set sampling combine through single slice processing behind show, it read number keep a view, accurate.Because the instrument adopted to load four lines system sampling, removed a load to lead the line influence of the electric resistance upon the electricity manifestation from the noodles.The electric voltage limit of the electric circuit, make the experiment be getting more safe, credibility.
16.Adopt ancient Ai method(gu-ai method) research member structure, measure agreeable Ci with negative Ci magnet susceptibility.The main structure have:Electromagnet and Heng galvanism source, numerical type Gauss account(the effect of Huo Er) and ammeter and volt account, have control dish of illuminate the system.The system adopted a PID electronics to regulate, total amount word power supply(0~10 As have no the class regulate), do not need water cooling, make the instrument move a mineral layer movement more stable credibility, prevent°from because of operation not appropriate but result in the instrument damage.
34. This instrument is handled system by the optical system and the signal two part constitute, it according to only clap a Pin principle design, pass light electricity conversion examination, show a machine top to observe in the meantime in the commonness and the wave of twoer bunches of light form and mutually, measure light distance bad with differ and beg velocity of light.
The adoption is new of cent Pin, trigger measure, can observe a precision in showing a machine, clear wave form.
35.This device measures a spiral line tube stalk to distribute toward the magnetic field strength with the principle of the effect of Huo Er.Can judge semi-conductor to carry sign of flow the son, move to open a spiral line tube, can do total yoke coil an experiment.
This device from the measurement instrument and the appropriation power supply two part constitute, test an instrument to up have a spiral line tube, the component of Huo Er, two dimensions move surveyor's rod and IM, IH, VH conversion switch.The appropriation power supply provides the Huo Er the component work electric current IH, the spiral line tube Li magnetoelectricity flows IM and to the diagraph of Huo Er electric voltage VH.The diagraph of current and voltage all adopts 31/2 numbers show form and measure accuracy Gao.
