In the EDM process，material is removed by a series of discrete electrical discharges that occur in the machining gap between the cutting tool (electrode) and the test specimen (work piece) [6].
In the tests, new-style antiseptic material with excellent antiseptic capability was confected.
Polystyrene glue and silica gel were selected as anti-corrosion materials.In order to protect strain gauges from damage,the double layers of protection were applied on the strain gauges before testing.
Fig.1 Protection Zone Fig.2 Test Equipment The cutting tool was made of brass, as it is an excellent electric conduction material.

Ultrasound Imaging Using Spatial Domain Phase Information Liu Yanga, Chunguang Xu, Xinliang Li, Ye Huang Key laboratory of Fundamental Science for Advanced Machining, Beijing Institute of Technology，Beijing, 100081, China.
Most of the ultrasonic tomography is in transmission mode [10-12], but in the case of hard tissues or other sound impenetrable materials, this would result in no signal on the receiving side, so reflection mode imaging [13, 14] is a good alternative under this circumstance.
Polyurethane is one of the most valuable medical synthetic materials.

Introduction : Refractory metals due to their high melting points and high creep resistance, are candidate materials for many high temperature aerospace components in general and for propulsion systems in particular.
Despite their high melting temperatures, refractory metals readily oxidize at moderate temperatures which have restricted their use also as high temperature materials [6].

And this can reduce material and oxide skin.
When temperatures of journal and crank arm are almost same, they drop together. 3.
Because of the increasing distance between position and crank hole, heat quantity reduces on the material near crank hole.
