The main goal of each laboratory stand is to stimulate a high intensity cavitation phenomenon and to evaluate the cavitation resistance of new structural materials.
The assessment of cavitation resistance of structural materials is also carried out on devices simulating the impact of microjet taking place in the final phase of the cavitational bubbles implosion.

Presently, the constructed wetlands in operation have comparatively high removal rate of total suspended solids and organic materials, while the nitrogen removal efficiency is relatively low [5].
Presently, researchers have made use of measures strengthened oxygen to enhance the nitrification capability, oxidation and decomposition capability of organic materials [10-12]; further, denitrification process was promoted in wetland by carbon resource addition from outside [13, 14].

Microchannel geometry The microchannel[Covalent Materials Corporation, Japan] used in this research has rectangular configuration as showed in Figure 1.
Image reconstruction algorithm for ERT in microchannel The objective of ERT is to create a tomogram representing the electrical resistivity distribution of materials flowing within some column from voltages measured at the periphery of the sensor in response to the injected electrical current.

The ultrasonic wave has some characters diffracting on the vacant inside the material and being refracted at interface.
Therefore, in this research, to improve the capacity of detecting the decay of wood using ultrasonic wave, we assess the influential factors by the natural characters of wood and the factors affecting on velocity through the change of ultrasonic velocity according to the location and the size of decay on artificially decayed sample and find out the cause through an anatomic experiment�� Materials and Methods Materials.
The official species of the material used this research were a pine tree and specimens were made 3 type according to the experimental method like Table 1.
