Its characteristics are: has three distance mode for selection by jumper J1 (short range mode, mid-range, adjustable distance);
l Short range mode: 10cm—80cm or so (depending on the surface of materials measured decision);
l medium range mode: 80cm—400cm or so (depending on the surface of materials measured decision);
l Adjustable range mode: Adjustable parameters determined by the scope.

In the present work, ferrite-cerium-manganese samples have been prepared via a simple precipitation method using Fe(NO3)3×9H2O, Mn(NO3)2 and Ce(NO3)3×6H2O as starting materials, and NaOH, NH4OH and Na2CO3 as precipitant agents.
Fe(NO3)3×9H2O, Mn(NO3)2 and Ce(NO3)3×6H2O were used as starting materials, and NaOH, NH4OH and Na2CO3 as precipitant agents.

Abstract.
Design In order to decrease the skin effect loss at high frequency, it is necessary to use low resistivity metal materials to form the conductor.
In our work, we choose low resistivity material, for example, copper as the conductor.
Therefore, if the material, size and working frequency of mental coils are known, the total impedance can be calculated, just as follows: = Re() (9) High frequency signal delivered in inductor will produce vortex induced electric field in mental wires.

Abstract.
Still, the heat transfer phenomena of the single-roll process are complicated by the accompanying phase changes of the moving solid/liquid interface as well as the flow of the material in both liquid and solid phases [3,4].
- All material properties are constant and isentropic

In practice of engineering,
the cracks are often found near the inclusion when the forces applied to the composite materials
containing inclusion.
As a result, it is important to study this problem especially for non-destructive inspection and strength designing of the composite materials.

Introduction
There are complex components of pollution material, poor biodegradability in straw pulp papermaking wastewater.
From Fig.1 and Fig.2 showed, there were irremoved material which were phthalic acid mono-2-ethylhexyl ester and Diisobutyl phthalate (DIBP). 1.
According to the characteristics, it used absorption intensity of wastewater at the 254nm wavelength to reflect the number of aromatic substances, and to indirectly reflect the removal rate of material difficult to be biodegraded by the combination process.
