Ps formation energy is 6.8eV in vacuum and then 4~5eV in condensed materials.
It means that Ps formation is impossible by just placing positrons in materials.
Ps has negative work functions in many materials and then Ps prefers to stay in vacuum.
If there are holes in materials, Ps can be trapped.
The reactions of OH are very important in many researches such as the DNA damages or materials science for nuclear reactors.

Standard round rod samples for tensile tests were produced from this solution treated and aged materials.

Legal regulation of vegetables quality and safety Xiaomei Fu Weifang University of Science and Technology, Shouguang Shandong, 262700, China; E-mail:fuxiaomei211@163.com Keywords: Vegetable safety; Regulation; Regulation; Law enforcement Abstract: Safety is the main factor of vegetable production, management and consumption.
At the same time, our government should also increase investment in science and technology, and to raise the transformation rate of scientific and technological achievements for vegetable industry, especially the commercialization, industrialization of high-tech achievements to create a comfortable environment, encourage enterprises to increase investment in research and development, improve the scientific and technological innovation ability, is advantageous to the transformation of scientific and technological achievements of industrial policy, optimize the structure of vegetable industry. 3.4 Strengthen the special vegetable safety, formed the entire regulation Some developed countries pay attention to the regulation, establish archives for each vegetables, agricultural producers, farmland is located, the use of pesticides and fertilizers, the use of the information such as number, date of harvest and sell all want to put on record, through the whole process supervision, the vegetable
Therefore, China will continue to crack down on fake vegetables behavior in production and management, in view of the vegetable production in the process of using national disabled poisonous and harmful material, vegetable production enterprises and catering units abuse of additives, unlicensed vendors, such as the sale of counterfeit goods, the entire vegetable safety regulation, special focus on high-risk vegetable safety, ensure the safety of vegetables work orderly. 4.
