Protection of Laborers Occupational safety rights from the Perspective of Human rights law LU Fanghua , a * 1School of Humanities and Social Sciences, China University of Mining & Technology (Beijing), Beijing 100083, China alufanghua@126.com Keywords: Occupational Safety Rights; Human Rights Law; Human rights protection; Abstract.
As a basic human right, occupational safety right of labors refers to the right of being free from the dangerous factors in workplace during the working process in the eyes of law [References [1] Guo Jie, On the Occupational Safety Right of Labors and Leal Protection.Journal of Jurist Vol.2 (2007) ,p.9. ].
According to the international labor Organization convention and its Proposal, the occupational safety right mainly refers to safety problems which generated in the main behavior relation between material requirements of work, supervision for workers as well as the adaptability of machine, equipment, working time, working organization and working process to the mind and body of workers.
It offers a crucial insight for the observation and analysis of occupational safety and health rights in China [[2] Yan Ye, Social Structure of China Coal Mine Accident, Social Sciences Academic Press(2012). ].
Journal of Safety Science and Technology vol.9(2013), p.182. ] Human right inspection for occupational safety rights in China Viewed from the point of human rights, the above mentioned laws and regulations also have both advantages and disadvantages.

Especially, magnetite Fe3O4 nanoparticles are an important magnetic material and have been widely used in many industrial and biological fields due to their strong magnetic and low toxicity properties.

After the 1960s it began to gradually take on the development trend of some science and technology flow, it generally followed the throwing mode that combined some data model and scientific calculation and the angle of throwing shot put and pace and other objective factors that affected forward route of shot put.
Research methods 1) Literature material investigation According to the relevant literature, it carried on the investigation of achievements of our three outstanding woman shot-putters in the international large game and the related index data of their final exertion, the result can be seen in table 1.
With the development of science and technology and the deepening of the training practice, combined with the scientific model of training mode has become a trend of movement.

Trial and error approach is inadequate for assessing the relationships between the operational parameters and process performance because of the complexity of the interacting physical phenomena, the high operating and material costs, and the difficulty of obtaining detailed and precise measurements in a high-temperature environment.
