The results show that the available B in western Jilin is in a middle level,the content in Nong'an is higher than that in the others; the available Mn is extremely abundant; the available Cu in Nong'an is obviously higher than other areas,and the content in Da'an differs greatly; the available Zn is in a middle level; the severe shortage of available Mo differs between different areas; and the available Fe is extremely abundant. The available Mn,Cu and Fe have significantly positive correlation with their total content; the available B has significantly positive correlation with pH,and Zn has obviously negative correlation with pH; the available Mn and Fe had significantly positive correlation with soil organic matter.展开更多

The increasing accumulations of N, P and C in seeds implied that the nutritive quality in seeds was higher at the regions with relative higher mean annual temperature(MAT) and mean annual precipitation(MAP), while that in pods was on the contrary. By contrast, pod nutritive content was relatively high, but seed nutritive content was relatively low at the regions with relative high MAT and MAP. In addition, C:N ratio in pods was significantly and negatively correlated with MAT and MAP, while that in seed was significantly and positively correlated with MAT and MAP. The partitioning patterns of N-compounds between pods and seeds reflected different nitrogen translocations in the plant organs under various climate condition. The N:P ratios were negatively correlated with MAP, implying a higher proportional allocation of P to seeds than that of N in the areas with a relative high MAP. Therefore, the strategies to assess pod nutritional quality should be taken into accountfor nutritive translocation under various environmental conditions.展开更多

A comparative study of proxemics phenomenon between China and America finds that those two countries have a great differences. American seems especially sensitive to their body spaces, and Chinese don＇t care much about it. In the book The Silence Language, Edward hall first uses the term proxemics, and he has given a detailed analysis of proxemics. Proxemics is the study of spatial distances between individuals in different cultures and situations. Cultural factors for proxemics has a great influence, and the factors such as gender and religion also has a profound significance on proximics. This thesis will mainly analyze this phenomenon in the way of the definition and theory ofproximics, especially, the ways how people deal with the international culture situation. In order to improve the readers cultural accomplishment and ability to communicate, prevent the errors in the protocol, this paper will further explain how to solve these cross-cultural problems in cross-cultural context, especially for Chinese learners. With some fresh insights into international culture communication research, hopefully the readers may benefit from this paper and communicate with foreign people in a better way.展开更多
