The characteristic physical properties of titanium alloy materials of the electrical discharge machining (EDM) small hole is studied theoretically and experimentally.
Thereby, the main characteristic of EDM is described as follow: it can machining whatever conductive materials and not be restricted by its hardness; it can machining blind-hole; deep-hole; slant-hole and profiled hole on the slant; it has low cutting force in machining process and requires low strength and stiffness.

Surface properties of K9 glass/diamond materials were controlled under the optical brittle material by cold plasma assisted cutting machining.
Cold plasma jet can regulate and control the K9 glass/diamond materials surface property and improve anti-friction effect.
During the process, the cold plasma materials have many favorable processing properties.
There has nothing about high temperature thermal damage on the surface of the material or reduction the mechanical properties of materials.
This approach can increase critical cutting depth, and enlarge cutting material plastic domain thereby to prolong brittle fracture of materials.

Thus, LaAlGe2O7 doped Eu3+ is a potential red-emitting due to excellent luminescent properties and used as novel optical materials [5].
Generally, it is found that an excessive doping of emission spectrum ion in inorganic materials could significantly lower the emission intensity [11].
