There are three methods to estimate methane emissions such as measured method, material balance algorithm and emission factor method [4].
The third is Pharmaceutical manufacture which was 13231.51 tons and 8.65%.Wastewater from Chemical raw materials and chemical product manufacturing, Chemical fiber industry and leather furs industry have a relative low CH4 emission which were 4.98%, 4.75% and 2.80% respectively.

However, reaction products have more impurities and therefore acid purification is needed before the materials meet the requirements of the usage of high-purity ceramic powder.
Sample of heat generated from reaction materials continue to respond until it is finally ended.

Introduction Nanocomposite magnetic sensitive materials in a form of a pellet or polymeric matrix filled with different powders represent an interesting branch of engineering materials as they are frequently considered as an alternative to the conventional metallic magnets [1, 2].
Such materials find many applications as magnetic field sensors or magnetic field shielding materials in electronic equipment industry where the key issue is to protect the environment from electromagnetic fields.
However, potential application of the nanocomposite magnetic materials depends also on its resistivity to some external loadings which may damage the system.

Zero amplitude damping mainly comes from i)the defects within structure materials, ii)connection defects between members and iii)connection defects between wall and windows or doors.
Based on Lazan’s metal material energy dissipation theory, the material damping effect is considered in this paper.

Now, extensive research work has been carried out in this field which mainly focused on two types of zinc oxide based materials: zinc ferrite (ZF) and zinc titanate (ZT).
Besides, natural manganese ores were selected as raw materials for the desulfurization sorbent.
