Since long, because of different requirements when working ,belt running leanly in movement ,the carrying idler's short service life, on-site maintenance big work load and so on many breakdown reasons and crucial understanding insufficiency, have made the carrying idler's function research and manufacture not be broken through, These make the carrying idlers to transport the material in inexpensive economic cost expense not to be able to obtain manifests fully, which is one that hasn't good solution of comprehensive technical difficult problem.

长期以来，由于对皮带托滚在输送机上所处不同工况性能要求，运行中存在皮带易跑偏，易损坏，托滚使用寿命短，现场维护工作量大等诸多故障原因及关键性认识不足，因而造成了对皮带托辊的功能研究和制造无重大技术突破，使皮带输送物料的最佳效果的低廉的经济成本费用未能得到充分体现，是一项没有得到较好解决的综合性技术难题。

When analysing impact of IT on business, Professor Porter departed from his former ideology, his discussion is not all-sided and totally correct Being not considerate is that he commented impact on geographical scope and industrial scope only, excluding segmentary scope and vertical scope.

The enthusiasm are kept within limits because of insufficient expense investment; the rare chances for the coaches to exchange with their opponents and the poor ability of their scientific research makes them focus too much on the practical drill and rely on the experiential drill; the poor technical and ideological quality of the umpires are mainly to blame for unjustness of judgment.

由于经费投入不足等原因遏制了基层培养跆拳道后备人才的积极性；教练员外交流机会少，对运动训练全过程仍只抓训练实践活动本身，科研能力不强，经验训练占很大比例；跆拳道比赛存在裁判不公的现象，裁判技术、思想作风是造成裁判不公的主要原因；没有建立人才储备机制，大量17岁以后可以出成绩的运动员流失社会：基层运动员的学习质量无法保证，造成了运动员无法提高技术水平、就业困难等问题。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
