查询词典 reduction potential

Actually, the development of genetically-modified products is a double-edged sword: On the one hand, it contributes to the enhancement of the world crop yield, as well as the quality, and reduction of chemical fertilizer and the pesticide use, helps solution of the famine and undernourishment in developing countries. Besides, it also promotes the development of certain related industries like pharmaceutical and chemical industries; On the other hand, it also brings the unprecedented threat for human beings. We are unaware of the potential effects in human bodies, or any unknown injury to the next generation, caused by genetic modification. Nor can we forecast what kind of influence to the extant gene will emerge.

而事实上，转基因生物技术的确是一把双刃剑：一方面，转基因技术可以提高世界农作物产量、提高质量、减少化学肥料和杀虫剂的使用、解决发展中国家的粮食缺乏、饥饿和营养不良的问题，另外，基因技术的飞速发展在很大程度上也促进了医药、化工等相关行业的发展；另一方面，它也为整个人类带来了前所未有的威胁，人们无法得知基因序列的改变会在体内引起何种潜在的变化，无法确定转基因产品是否会对下一代产生任何未知的伤害，无法预测转基因产品对现存基因会产生何种影响。

分析数字地价模型得出结论：①地价从中心基点向城市边缘总趋势是降低，但不同方向表现出不同的特点；②在贯穿市区的地价剖面中，一般表现为从一个边缘到另一个边缘的地价由低到高再到低的变化规律，由於地价剖面经过不同的市区区位，呈现出正态和偏正态的分布特点；③在时间演化上，凹性地价阶地变小或变平缓，凹性地价阶地转变为凸性地价阶地，凸性地价阶地变小或转化为非地价阶地，凸性地价阶地变大或平缓；④利用地价增值率和地价增值速度分析了地价的增值潜力。
