The National Cancer Institute (NCI) in the U.S. defines nanotechnology as: "The field of research that deals with the engineering and creation of things from materials that are less than 100 nanometers (one-billionth of a meter) in size, especially single atoms or molecules.
Porous ceramic-based materials are useful in the encapsulation of bio-active agents (Yih and Al-Fandi, 2006).

In addition, ionic conductivities and compatibilities with electrode materials were emphatically reviewed.
Though high purity LiBOB can be synthesized by LiB(OCH3)4 and (CH3)3SiOOCCOOSi(CH3)3 in anhydrous acetonitrile (CH3CN) [10], the high cost of raw materials limits the generalization.
While, LiBOB is expected to solve the problem of dissolve erosion of Mn series cathode materials in electrolytes.
Meanwhile, LiODFB combined the advantages of LiBF4 and LiBOB, matched very well with anode and cathode electrode materials.

The design of mine-used infrared radiation thermometers shell for electromagnetic shielding Li ming Li,Ying Chen,Wei Lu (Taiyuan ZhongBo Academy of Information Science and Technology (limited company) North University of China taiyuan 030051 China) Key words: Infrared thermometer; simulation；Electromagnetic shielding; Shielding effectiveness Abstract: Mine high voltage power supply equipment on the hot temperature is too high, easy to cause the gas explosion accident, however the hot spot monitoring infrared thermometer surrounding is the existence of a large number of induced magnetic field,which influenced the temperature measurement accuracy, According to the infrared thermometer casing electromagnetic leakage, the shielding enclosure material of the infrared thermometer selected silicon steel, lens window electromagnetic leakage has become the main cause of the decline of electromagnetic shielding effectiveness.
Based on the actual project needs, we select silicon steel for the shielding material of the shell, which has the advantages of large permeability.
，are the magnetic conductivity and relative electric conductivity of the silicon steel copper,and we can find that ,.when setting the thickness of the electromagnetic shield, in theory, the thicker the better about the shielding shell, however, for practical projects, as long as the thickness of shielding material is 1.5 times of the thickness which frequency enter the shielding material ,that is enough, The thickness of the frequency into of the material is considered by the formula: =3mm, the thickness of shielding material available is so as to 4.5mm.

Teaching objectives of diversification and multi-level teaching is a network feature, the network is no longer just teaching to render content for the purpose of teaching, in addition to providing a rich variety of learning materials to help students acquire knowledge, learning content and different for different basic level students, also specify the multi-level teaching goals, develop a variety of targeted learning strategies so that each learner to develop.
Teachers should focus on online teaching material collection, accumulation, sorting, organizational management, development and construction and sharing, focus on network teaching resources dynamically updated and application evaluation.
