material characteristic
1.Selecting yam and reconstituted dried milk was prepared the new healthy beverage on the basis of raw material characteristic.
2.The cavity depth between the rigid panel and absorption material is adjusted in order to make the surface characteristic impedance of the absorption material mathch the surface characteristic impedance of the air, so the absorption coefficient is the maximal.
5.A deposit of fatty material on the inner lining of an arterial wall, characteristic of atherosclerosis.
8.The accumulation of acidity material in the blood inside body and organization, its characteristic is chroma of the pH indicator in blood rises, PH value falls.
9.By the methods of XRD, EPMA, metallographic examination, material quality and impunity analyses, the main reason about the characteristic of penetration and distribution was confirmed.
