农作物区域试验精确度分析是品种和试验环境科学评价的基础。本研究分析了2000―2014年期间长江流域、黄河流域和西北内陆棉区国家棉花区试的试验精确度分布与演变动态,并分析比较了棉花12个主要性状的精确度差异,旨在全面分析和评价我...农作物区域试验精确度分析是品种和试验环境科学评价的基础。本研究分析了2000―2014年期间长江流域、黄河流域和西北内陆棉区国家棉花区试的试验精确度分布与演变动态,并分析比较了棉花12个主要性状的精确度差异,旨在全面分析和评价我国棉花品种区域试验精确度的发展水平和演变规律,为全国棉花品种区域试验的合理布局和优化设计提供参考依据。研究结果表明:(1)单年单点棉花区域试验能鉴别出5%、8%、10%、12%、15%和20%品种间差异的比率分别约为20%、50%、70%、83%、92%和98%。(2)单年多点棉花区域试验精确度呈逐年提高的演变趋势,RLSD0.05(RLSD,relative least significant difference)由2000年的11.43%下降到2014年的7.1%,其中长江流域的RLSD0.05已经连续9年、黄河流域棉区的RLSD0.05连续4年稳定在5%以下,可以稳定地鉴别品种间5%的差异;西北内陆棉区的RLSD0.05也呈逐年下降趋势,目前可以可靠鉴别品种间10%的差异。(3)棉花12个主要性状的试验精确度差异显著,其中皮棉产量和结铃数的精确度较低,霜前花率、衣分、纤维长度和生育期的精确度较高,其余性状精确度中等。展开更多
In order to pursue the ideal criterion of ＂faithfulness, expressiveness, and elegance＂ initiated by the famous translator YAN-fu in translation and ＂accuracy, smoothness, and quickness＂ in interpretation in China,...In order to pursue the ideal criterion of ＂faithfulness, expressiveness, and elegance＂ initiated by the famous translator YAN-fu in translation and ＂accuracy, smoothness, and quickness＂ in interpretation in China, people have summarized some techniques to help the process. And generally speaking, trainers or teachers will introduce those techniques to the students respectively. Yet in this paper firstly, by taking examples from some of the text books and a few famous conferences in China, it makes a comparative analysis of the different techniques in translation and interpretation. The comparative analysis explores the most three common techniques： amplification, omission, and repetition in translation and interpretation, and draws the conclusion that translation is more formal, more rigorous, while interpretation is comparetively simple and flexiable. Based on the above analysis, then the paper suggests that the comparative analysis approaches should be used during the teaching process instead of the traditional one-way teaching.展开更多
