学术界 2014年第3期 302-306页

作者： han ling School of International Education Nanyang Institute of Technology Nanyang Henan 473004

Due to differences in value orientation,thinking model and other aspects of social norms,it is difficult to completely avoid cultural collision and conflict betw een cross-cultural communications. As an important channel of inter- cultural communication,verbal communication w ill vary depending on different gender styles. T he analysis of the impact of gender discourse on human activity in a specific context and the explanations of different discourse style can be helpful in better understanding the communicative behavior of human beings. Based on this,this paper makes a study of the gender differences in discourse style in the context of inter- cultural communication,first explaining several relevant concepts,and then discussing several gender differences in discourse style and the cultural reasons in inter- cultural communication attribution,last presenting some proposals for promoting gender cross- cultural communication.

Rare Metals 2006年第z2期25卷 146-149页

作者： CHEN ling han Jing YU Shengxue Department of Applied Chemistry Yanshan University Qinhuangdao 066004 China Department of Applied Chemistry Yanshan University Qinhuangdao 066004 China Department of Applied Chemistry Yanshan University Qinhuangdao 066004 China

In order to prepare ornamental and anti-corrosive coating on aluminum alloys, preparation technology of black micro-arc ceramic coatings on Al alloys in silicate based electrolyte was studied. The influence of content of Na2WO4 and combination additive in solution on the performance of black ceramic coatings was studied; the anticorrosion performances of black ceramic coatings were evaluated through whole-immersion test and electrochemical method in 3.5% NaCl solution at different pH value; SEM and XRD were used to analyze the surface morphology and phase constitutes of the black ceramic coatings. Experimental results indicated that, without combination additives, with the increasing of Na2WO4 content in the electrolyte, ceramic coating became darker and thicker, but the color was not black; after adding combination additive, the coating turned to be black; the black ceramic coating was multi-hole form in surface. There was a small quantity of tungsten existing in the black ceramic coating beside α-Al2O3 phase and β-Al2O3 phase. And aluminum alloy with black ceramic coating exhibited excellent anti-corrosion property in acid, basic and neutral 3.5% NaCl solution.

通过溶液流延的方式制备了不同拓扑结构带支链的聚(丁二酸丁二醇-对苯二甲酸丁二醇)酯(PBST-Kx)薄膜,利用^(1)H NMR、GPC、TG、DSC、XRD、流变测试等方法对PBST-Kx的结构及性能进行了研究。实验结果表明,支化剂的引入不会影响PBST-Kx分子链的化学组成、热稳定性和结晶性能,但随支化剂官能度的增加,PBST-Kx的支链数增加,Mn呈减小的趋势,分子量分布变宽。支化结构的引入增加了PBST-Kx的熔体黏度,使其具有更高的弹性和更长的松弛时间,且随着支化度的增加而增大。随支化度的增加,PBST-Kx薄膜的拉伸强度和断裂伸长率降低。

Long-distance blue light signalling regulates phosphate deficiency-induced primary root growth inhibition

Molecular Plant 2021年第9期14卷 1539-1553页

Although roots are mainly embedded in the soil, recent studies revealed that light regulates mineral nutrient uptake by roots. However, it remains unclear whether the change in root system architecture in response to different rhizosphere nutrient statuses involves light signaling. Here, we report that blue light regulates primary root growth inhibition under phosphate-deficient conditions through the cryptochromes and their downstream signaling factors. We showed that the inhibition of root elongation by low phosphate requires blue light signal perception at the shoot and transduction to the root. In this process, SPA1 and COP1 play a negative role while HY5 plays a positive role. Further experiments revealed that HY5 is able to migrate from the shoot to root and that the shoot-derived HY5 autoactivates root HY5 and regulates primary root growth by directly activating the expression of LPR1, a suppressor of root growth under phosphate starvation. Taken together, our study reveals a regulatory mechanism by which blue light signaling regulates phosphate deficiency-induced primary root growth inhibition, providing new insights into the crosstalk between light and nutrient signaling.
