8. Although the insulator elements vary greatly in their DNA sequences and the specific proteins that bind to them, they have at least one of two properties related to barrier formation. First, the activity of an insulator element is dependent on its position relative to the enhancer and promoter: it only interferes with communication between the latter two elements when interposed between them. Second, these boundary elements protect transgenes from the full spectrum of positive and negative chromosomal position effects.
尽管迄今所发现的各类隔离子在DNA序列、特异性结合蛋白等方面有很大的不同，它们都至少拥有以下两个功能中的一个：1、当隔离子序列位于增强子和启动子之间时，它能阻断两者间的通讯（enhancer-blocking）；2、当隔离子序列位于转移基因两侧时，它能保护该基因使其免受整合位点附近染色质微坏境的影响，即克服位置效应（position-effect protection）。

9. Judging from our analysis, the jumping performance doesn't develop harmoniously with every quality. Six among nine qualities have positive effects on the improvement of jumping performance, however, 100-metre run, run-up jumping of five steps and complete squat are negative, and what more, it's the inharmonious factors of hindering the systematic development.
通过分析我们可以看出，关英楠跳远成绩与各项素质发展不协调，9项素质中的6项对跳远成绩的提高有促进作用，而100m跑、助跑五级跳远和全蹲则起到了阻碍作用。

10. A econometric model is applied to test those potential effects. The results of regression show that the growth of fixed capital investment have a positive effect on the degree of harmonization, the upgrading of ratio of non-agricultural industries has a negative effect on the degree of harmonization, the disparity of income per capita in urban and rural residents has a negative effect on the degree of harmonization.
回归分析结果表明，经济快速增长时期，固定资产投资增长对农村劳动力转移与农地非农化协调度存在显著的正向影响，系数估计在5％的水平上显著；二三产业比重增长速度对农村劳动力转移与农地非农化协调度存在显著的负向影响，系数估计在10％的水平上显著；城乡居民收入差距对农村劳动力转移与农地非农化协调度存在显著的负向影响，系数估计在1％的水平上显著。

11. The Suzerain-Vassal System had both positive and negative effects on the formation and development of China as a nation with different nationalities: on the one hand, it had long been the significant promotion for China to grow into a big nation with different nationalities; on the other, it later was more of a hindrance to unifying different nationalities into a big nation in the Ming and Qing Dynasties.
这一体制客观上对中国统一的多民族国家的形成和发展带来了正反两方面的影响：一方面，它在较长历史时期中对中国统一多民族国家的最终形成和发展起着不可忽视的推动作用；另一方面至明清时期又阻碍了中国统一多民族国家的发展。

18. With the increase of superficial gas velocity in the riser, the negative pressure gradient in standpipe decreases gradually and keeps steady finally. The negative pressure gradient and slip velocity in standpipe increase with the increase of circulating rate. Effects of aeration added to pyrolysis chamber on the gas/solid flow state are complicated. With superficial gas velocity in the riser and valve orifice at the bottom of the standpipe kept invariable, the flow pattern in the standpipe changes from negative pressure difference to positive pressure difference as the aeration increases.
