The paper has given out the main specifications and introduced the trveling sys- tem,scraper Conveyor,auger,the control of engine speed,the driving of auger,the mation of vibratory beam,the design of hydrostatic pipe line and the heating equipment in screed.
Influences of main parameters such as rotation speed, blade thickness,semi-cone angle and lead of screw conveyor on its strength and deformation were studied. It would provide parameters for the optimization and actual application of existing screw conveyor.
s Conveyer-instrument for biliary stent transportation and placement was trial manufactured from medical material or non poisonous material (medical PVC?PE etc) Based on the study of the processing technology and bonding technology, suitable parameters and prescriptions were chosen out, and a non reusable conveyer instrument was developed successfully The results of test showed that all the technical index had met the requirement of design, and the clinical tryout results proved that the product could fit the clinical requirement
Methods The stent made of stainlees steel Z type covered with thin membrane or Ni-Ti shape memory wire mesh-like stent was used and placed through mouth by the transport of tracheal stent in 12 cases.
Methods Using 12-F introducer, percutaneous management with separating stent-graft was performed for aortic dissection Type B (1 case), thoracic aortic aneurysm (1 case), and abdominal aortic aneurysm (2 cases).
Methods Retrospectively comparing the two methods of direct-pushing of the delivery system and the guide-wire intermittent plucking technique as the delivery system passing through the aortic arch.
The numerical modeling of three-dimensional phenomena has become possible with the appearance of a new generation of computers with conveyor processing of large numerical files.
A method of the in-process measurements of large-size lumps in a conveyor-transported crushed material based on measurements of the X-ray or gamma radiation reflected from the material surface is proposed.
In the fibroblasts, their exchange takes place mostly at the expense of depolymerization of the liberating negative ends, which agrees with the previously proposed conveyer hypothesis of microtubule assembly on the centrosome.
A unique solution for the magnetic susceptibility of a half-space has been found as a function of current signals of an MB-5 conveyer inductive sensor [1] on the basis of the known studies of ill-posed problems with a priori information [5].
