Magnetic NW arrays based on various magnetic materials and alloys can be a basis for new types of memories, or used to improve already existing devices.
One of such interesting magnetic materials is a CoNi alloy, which can exhibit either a soft or a hard magnetic behavior, depending on the Co content in the alloy [7-10].

So, this is inconvenient to encourage science researchers to invest.
On the other hand, lots of developed countries prescribe that the product which used in science research or the reading materials, college teaching materials, science journals which used to develop science technology are all free of tax.
On the other hand, the field technologists who serve in crawl material production industries can enjoy preferential income tax in accordance with their continuous length of service.
We suggest that the science developing industries, science research structures and colleges’ science developing which provided by the loans of banks are free of interest tax, stamp tax, sales tax and income tax.

The mechanical properties of different type of all-ceramic crown are evident different because of the differences of materials and production process.
Introduction Dental ceramic materials have similar color and translucency to natural tooth, performance, stability, good biocompatibility, corrosion resistance, aging and wear and tear, etc., which is favored deeply by the doctors and patients, is the most promising new materials of the oral prosthetics.
This is the metal materials and other macromolecule can not compared, and gradually been widely used in the field of prosthodontics.
The VITA model is composed of three materials (ceramic, bounding layer and abutment), the GI and Emprss model are composed of four layers materials (ceramic, bottom crown, bounding layer and abutment).
