However, the thickness and density of non-woven materials are the two most important factors.
In our study, three samples of the same thickness, different density materials are studied.
Meanwhile, the sound can be reduced by propagating in the materials.
So the corresponding acoustic absorption materials required for the performance are weakened.
Besides, due to limited experimental conditions, this article only conducts some superimposed contrast experiments on bulk density ratios of two different materials, and in the future we can combine with three or more different materials of different density, and compare with single-layer materials, in order to identify the best ratio.

As the reaction effect unique to microwave radiation, such as rapid heating mode and effect of significantly improve in the system response speed and so on, that it has been rapidly applied in material science, and for some reaction can make the reaction rate than the conventional method is increased by two to three orders of magnitude.
Microstructure and phase structure of materials can be effectively controlled by modified doping[6-7].
Using cupric nitrate and thioacetamide (TAA) as raw materials, twelve sodium dodecyl sulfate as surfactant, synthesis of nanometer copper sulfide precursor by microwave radiation,stripping precursor for 14 days by n-BuLi to produce the tungsten doped nanometer copper sulfide with the method of microwave hydrothermal synthesis.

First-Principles Calculations For Electrical Proterties Of The Lead Anode Plate Fuli Wanga, Jingchao Chenb, Jie Yuc (Key Laboratory of Advance Material of rare Precious and Nonferrous Metals, Education Ministry of China; and Key Laboratory of Advanced Materials of Yun nan Province, Kunming University of Science and Technology,Kunming650093,P.K.China) a460677928@qq.com,bcjingchao@hotmail.com ,cyujieone@163.com Keywords: anode materials; fermi energy; electrode potential; first-principles; lead base alloy Abstract: Four kinds of fermi energy of lead anode plate were calculated by using first-principles.
Different metals and different alloy elements of the fermi energy level were compared, the minimum electrode potential lead base alloy anode materials is known.
So the Pb-Sb alloy is expected to become the electrode potential minimum lead base alloy anode materials.
In order to reduce the energy consumption and the cost of anode materials, to reduce electrode potential is the pursuits of the majority of wet smelting workers, so explore new anode materials was the research topic in recently.

The inelastic strain tensor can be factorized into four parts, i.e., , the classic plastic strain which satisfies J2 theory and steel plates are isotropic hardening materials, , the thermal expansion strain, , the transformation dilatational strain and , the transformation plasticity strain tensor.
The above material model is implemented into the commercial finite element package ABAQUS Standard and the elastic modulus of materials are listed in the table1.

The main obstacle in the operation of such coatings is the ability of these materials to dissolve in water.
An urgent task is obtaining new functional materials based on environmentally friendly biopolymers of plant origin, made from renewable natural raw materials.
