REN, which acted as an accelerator in the phosphating solution, could catalyze the surface reaction and accelerate the phosphating process. REN mainly enabled the P in the phosphate coating to exist in the form of PO4^3- and promoted the hydrolysis of phosphatic acid in a liquid layer at the cathodes. This resulted in the evolution of H2 at the cathodes, which increased the local pH value and in turn drove the precipitation of the phosphate coating. Additionally, REN was adsorbed on the surface of the aluminum substrates to form a gel during the phosphating process. These gel particles were good crystal seeds, which helped to form phosphate crystal nuclei and possess the function of a nucleation agent that could decrease the phosphate crystal size. The corrosion resistance of the formed zinc phosphate coatings was improved.展开更多

Of them, 44 % cases were cured, 33 % markedly effective and 20 % improved. The total effective rate was 97%. Acupoints of Ren channel selected: Zhongji (CV 3), Guanyuan(CV 4), Qihai(CV 6) and Yinjiao(CV 7); Crossing acupoints of Chong channel selected: Qixue(KI l3), Siman(KI 14) and Zhongzhu(KI 15). Filiform needles of No. 30, 1. 5 cun were adopted to puncture the above acupoints with the uniform reinforcing-reducing method, and the needles were retained for 30 minutes. At the same time, the moxibustion was applied to the place of retaining needles until the skin flushed.展开更多

Lau's versions of Mencius, a comparative study will be conducted on the key philosophical term: Ren. After comparison, reasons for the differences will be stated. Targeting at missionaries, James adopted the 19 century old English and strived for faithfulness. Lau's translation work is of high academic value and receives good comments popularly in western sinology circle, being considered as the exemplary work for translating Chinese classics into English. Zhao et al. translated Mencius for modern readers, who might have acquired more knowledge of China and want to learn something about Mencius. Quantitative analysis shows that Ren appears 157 times in Mencius, and"benevolent/benevolence"gains a dominant position in these three versions.展开更多
