Effects of Sulfur Introduction on the UV and the Visible Emission Properties of ZnO
Hongying Guo,Feihong Jiang,Run Yuan,Jun Zhang,Yuanping Sun,Yifan Liu,Yongxin Qiu,Taofei Zhou,Xionghui Zeng,Baoshun Zhang,Ke Xu,Hui Yang 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.66 No.4
Hexagonal ZnO particles have been synthesized by using the hydrothermal method with differentsulfur concentrations in the reaction solutions. Structural and optical characterizations have beenconducted to study the effects of the sulfur in the reaction solutions on the properties of thesynthesized ZnO in the ultraviolet (UV) and the visible (VIS) bands. The existance of sulfur inthe solutions can help to introduce compression strain along the a axis and an opposite trend forthe parameter c with strain inside the formed ZnO particles, which means the total strain in thesamples is presented along the c axis. The average size of the ZnO particles, as calculated fromSEM images, shows the same trend as the strain in the samples. The increasing incorporation ofsulfur causes an increase in the VIS luminescence band, which can be attributed to an increase inthe number of sulfur-induced defects.

Analysis of Chinese Residents in Housing Wealth
Jiao Wang,Hongying Yuan 아시아무역학회 2015 Journal of Asia Trade and Business Vol.2 No.1
In recent years, the housing wealth of our country increased rapidly. Wealth is very important for every family, it is the basis of the people’s basic needs. Therefore, it is necessary to conduct a comprehensive analysis of household wealth. In this paper, we analyze some aspects of family wealth like these: the meaning and measure of wealth; the source of housing wealth; the characteristics of the distribution of household wealth; the reason the difference in household wealth; Countermeasure. As a result, we found a lot. There are four sources of household wealth. They are savings deposits, real estate investment, development of capital markets and wealth inheritance. We analyzed three aspects of the characteristics of household wealth. These three aspects are the income distribution, industry distribution and regional distribution respectively. There are three main reasons for the uneven distribution of household wealth. The three reasons include the disadvantageous income distribution system, the disadvantageous tax system, the imperfect social security system. On this basis, We make recommendations to deal with the uneven distribution of household wealth. Firstly, it is necessary to improve the wage system. Secondly, the need to reform the tax mechanism. Thirdly, we need to improve income distribution mechanism. This means that it is necessary to optimize our systems. In addition, we should improve labor income and adjustment to capital gains reasonably.
