The Human Rights Legislation Practices of the Communist Party of China During the War of Liberation

During the War of Liberation,the liberated areas,under the leadership of the Communist Party of China,kept deepening and developing the concepts and ideas of protecting human rights,promulgated a series of human rights laws and related administrative programs,and put them into practice.The contents included not only the political rights of citizens but also their economic,social,and cultural rights,with emphasis on the protection of the rights to subsistence and development.The human rights legislation in the liberated areas has a wartime and class-based nature due to its social environment.It reflects the transition of the Communist Party of China from a revolutionary party to a ruling party on the historical stage.It played an important role in directing,advancing,and promoting the progress of democracy and the rule of law at that time and accumulated experience for the human rights legislation after the founding of the People’s Republic of China.History proves that the Communist Party of China has always been a political party dedicated to fighting for the human rights of the Chinese people,and only the Communist Party of China can lead China’s human rights development to a deeper level.

The Study of Chamber Rockburst by the CUSP Model of Catastrophe Theory

By means of CUSP model of catastrophe theory. this paper has studied thephysics process of rockburst occured on circular chamber. The present paper has nolonly described the instability process of rockburst more deeply. but also got the crilicaldepth of plastic softening area of chamber that is valuable in the controlling engineering of rockburst. the chamber displacement jump and energy liberation have been derived. the influence of rock parameters on the rockburst has been discussed .

Mechanism of Suppressing ASR Using Ground Reactive Sandstone Powders instead of Cement

In order to understand the effect of powders ground from reactive sandstone replacing cement on reducing or suppressing alkali-silica reaction（ASR）, and to identify the mechanism of suppressing ASR by this powders, mortar and paste containing reactive sandstone powders of four replacement levels ranging from 10wt% to 40wt% and four specific surfaces areas ranging from 210 m^2/kg to 860 m^2/kg were studied. The experimental results showed that incorporation of 40wt% reactive sandstone powders could suppress ASR effectively except for mortar containing reactive sandstone powders with specific surface area of 610 m^2/kg, which disagreed with the most results reported that the higher reactive powder specific surface area, the smaller ASR expansion. By means of fl ame photometry, Fourier transform infrared spectroscopy（FT-IR） and thermo gravimetric analysis（TG）, the mechanism of reactive sandstone powders on reducing or suppressing ASR was soluble alkalis type of reactive sandstone powders and the competition of liberating and bonding alkali of cement paste containing reactive sandstone powders,when the ability of alkali bonding was greater than the ability of alkali liberation, ASR caused by reactive sandstone was supressed effectively.
