目前,在洪水频率分析中,一般事先假定实测洪水系列服从某一线型,例如,服从P-Ⅲ型分布,再用参数统计方法分析洪水频率。然而,这种假定在多数情况下是不合理的,甚至会产生严重的后果。本文用非参数核估计方法对洪水系列分布的概率密度进行了估计,结果显示,非参数核估计法不仅具有事先不需要假定总体的线型的优点,而且估计的结果与参数统计法相比具有较高的精度。

Effect of calcium formate as an additive on desulfurization in power plants

引用

Journal of Environmental Sciences 2018年第5期30卷 89-95页

作者： Zhenhua Li Chunfang Xie jing Lv Ruiguo zhai Key Laboratory for Green Chemical Technology of Ministry of Education School of Chemical Engineering and Technology Collaborative Innovation Center of Chemical Science and Engineering(Tianjin) Tianjin University Tianjin Zhongtian Science & Technology Co. Ltd.

SO2 in flue gas needs to be eliminated to alleviate air pollution. As the quality of coal decreases and environmental standard requirements become more stringent, the highefficiency desulfurization of flue gas faces more and more challenges. As an economical and environmentally friendly solution, the effect of calcium formate as an additive on desulfurization efficiency in the wet flue gas desulfurization（WFGD） process was studied for the first time. Improvement of the desulfurization efficiency was achieved with limited change in p H after calcium formate was added into the reactor, and it was found to work better than other additives tested. The positive effects were further verified in a power plant, which showed that adding calcium formate could promote the dissolution of calcium carbonate, accelerate the growth of gypsum crystals and improve the efficiency of desulfurization. Thus, calcium formate was proved to be an effective additive and can potentially be used to reduce the amount of limestone slurry required, as well as the energy consumption and operating costs in industrial desulfurization.

Study on the Formation and Construction of the Cultural Empathy in the Cross- cultural Communication

引用

学术界 2014年第7期 282-288页

作者： Wang jing zhai Zhiqun International College Zhejiang Yuexiu University of Foreign Luages Shaoxing Zhejiang 312000 English College Zhejiang Yuexiu University of Foreign Languages Shaoxing Zhejiang 312000

The development of globalization has promoted different regions to be closely linked and the boundaries between different cultural cycles to be gradually broken,so that the communication and integration between different cultures emerge. In cross-cultural communication,cultural empathy is not only a problem and necessarily implemented strategy,but also plays an important role,so people must improve their own cultural sensitivity,set up the awareness in cultural empathy on the basis of recognizing cultural diversity and equality,break the thinking inertia in the local culture and increase the consciousness in cognizing cultural empathy,put aside the idea of cultural centralism and strengthen the cultural inclusivity,and widely understand the basic cultures of other countries and reduce cultural empathy.
