Ultrasonic wave examination development summary
 
The high velocity, the high efficiency is the modern industry symbol, but this is the establishment above the high grade foundation. The design and the craft personnel should understand that,Must a organizational structure, stochastically has microscopically, the macroscopic flaw, may sometimes even be frequently only can depend upon not damages the examination technology the utilization only then to give to discover, appraisal. Certainly, this with dozens of year in every way value and the general jobholders' difficult endeavor, causes not to damage the examination technology to have certain ability in this aspect to concern. Now, in the industry developed country, not damages the examination in the product design, the development, the user departments already by the fruitful utilization, in 1981 American former president Reagan in not damaged the examination academic society 40th anniversary congress to US in the letter of congratulations to say: “You can give the airplane and the spatial flight vehicle, the power plant, the ships, the automobile and the building and so on bring a greater degree the reliability. Not has not damaged the examination, we not impossible to enjoy at present in these domains and other domain leading status.”Not damages the examination by the swift and violent potential to the depth development, the objective need is after all the biggest power which one specialty may develop.
Our country not damages the examination technology is grows out of nothing, develops gradually from the lower stage to the application popular present stage level. Ultrasonic wave instrumentation development production, also presses this rule development change approximately.
The 50's, our country starts from the overseas introduction ultrasonic wave instrument, many is the unwieldy electronic tubular instrument. If England's UCT-2 ultrasonic wave instrumentation, reaches 24Kg again, various units do the experimental study work positively, has obtained the good effect in some project examination.
At the end of the 50's at the beginning of 60's, the domestic scientific research unit imported Poland to produce the ultra acoustimeter, and carried on the imitation production. Afterwards, Shanghai Tongji University develops the CTS-10 nonmetallic supersonic instrumentation, also is the electron tubular, instrument heavy approximately 20Hg. This instrument performance is stable, the profile is clear. But at that time this kind of instrument only then the individual scientific research unit used, the construction work department used not not many. Until 70's intermediate stages, because not damaged the examination technology still to be at the experimental stage, the promotion has not popularized, therefore the instrument big development, still has not used the electronic tubular UCT-2,CTS-10.
In 1976, after National Construction committee Office of Sciences managed holds the nation architectural engineering examination technology meeting, National Construction committee not damaged the concrete the examination technology to list as the key attack project, the organization nation 6 unit cooperation attack. Henceforth, not damages the examination technology to start to enter has the plan, has the goal research stage. Along with the electronics industry rapid development, the transistor unit has replaced the electron tube component gradually, is more advantageous to not damages the examination technology the promoted popularization. If the Romanian N2701 ultrasonic wave reflectoscope reflector, is composed by the transistor discrete component, has the profile and the numerical code demonstrated, instrument weight 10Kg. The 70's, English C.N.S Corporation promotes only has the 3.5Kg heavy PUNDIT portable ultra acoustimeter.
In October, 1978, Chinese Construction Academy of science developed JC-2 portable ultrasonic wave instrumentation. This instrument uses the TTL line, the numerical code demonstrated that, the instrument weight is 5Kg. Develops same time the supersonic instrumentation also has SC-2, CTS-25, SYC-2 ultrasonic wave instrumentation. Henceforth, our country had the ultrasonic wave instrument which own produce, not damaged the examination technology for the promoted application to lay the good foundation. (责任编辑:admin)
