Parting materials, which are usually used to prevent sticking of the strip to the roll, were not used, because magnesium alloy usually does not stick to the roll when the roll load is small.

When testing building materials, electroacoustic methods are suitable for determining the dynamic modulus of elasticity, for determining the strength of a specific material, and for evaluating the extent of damage [4].
[9] This velocity depends on the quality of the investigated material.
Ultrasonic measurement can be applied on structures made from concrete as well as wooden, metal, ceramic, and other materials.
The resonance method consists in measuring one of the natural frequencies of the tested material.

In order to study seismic behavior of double web-angle and top-seat-Angle connections, finite element methods, which included material, geometric and contact nonlinearity, were used to the model under cyclic loading.
When the grade and diameter of bolt were small, the bearing capacity of joint would be too little ,but caused for wasting of material.

It is found that drilling method, speed of rotation (SOR), material properties, and length of compression drillstring all can influence parametric resonance zones.
Apart from SOR and drilling method, other factors such as material properties, length of compression drillstring and so on can also influence parametric resonance zones.
