As the fourth quarter of this year's negative growth of the economy than the basic ring have been identified, in the first quarter of next year will be lower year-on-year growth, but the ring may be slightly better than the growth rate; the United States and Europe to consider economic trends, the impact of the policy of delay and inventory required to digest Time, around the second quarter of next year's economy will gradually pick up, GDP is expected to grow 8.2 percent throughout the year.

由于今年的经济负增长环比第四季度基本已确定在明年第一季度将是较低的按年同比增长，但环比可能略有增长速度越好，美国和欧洲，考虑经济发展趋势，围绕明年的经济第二季度的延误和库存政策的影响需要消化的时间，将逐步回升，国内生产总值预计全年增长百分之八点二。

The segment arrangement on circular curves has proven theoretical support;the segment arrangement on transition curves,however,has no theoretical support and is usually executed by means of VMT systems equipped on shield machines.

对于圆曲线的管片排版已有了相对较为成熟的理论，而缓和曲线上的管片排版以往通常是根据盾构机VMT来选择，没有成型的理论支持，为此，结合测量理论和弯环管片的实际，探索出在缓和曲线上准确选择弯环管片理论排版的方法。

III.Rafts and dories may have taut perimeter lines threaded through the loops provided.

III。筏和舫上应该有系紧的，带螺纹的，穿过圆环而环船的绳。

The machine has the advantages of big conveying capacity, high hoisting height, stable and reliable running and long working life. Its performance and parameter accord with JB3926—85 'Vertical Bucket Elevator', which consults the international standard and advanced foreign standard and the towing circle chain accords with MT36—80 'High-Strength Circle Chain for Mine'. The machine is applicable for conveying the power, grain and block materials, such as coal, cement, block, sand, clay and ore. The bucket elevator is allowed to convey materials with high temperature with the special circle chain structure

斗式提升机具有输送量大，提升高度高，运行平稳可靠，寿命长显著优点，其主要性能及参数符合JB3926----85《垂直斗式提升机》（该标准等效参照了国际标准和国外先进标准），牵引圆环链符合MT36----80《矿用高强度圆环链》，本提升机适于输送粉状，粒状及小块状的无磨琢性及磨琢性小的物料，如：煤、水泥、石块、砂、粘土、矿石等，由于提升机的牵引机构是环行链条，因此允许输送温度较高的材料。

Based on the experimental results, it could be consequentially concluded that N-methoxycarbonylation of aromatic amines was followed by the exclusive N-methylation of methyl N-aryl carbamates during the reaction process.

苯环上有钝化基团的一级芳胺反应活性比较好，获得N-甲基-N-芳基氨基甲酸甲酯的产率较高，反应时间也较短；而苯环上活化基团的存在，则会降低一级芳胺的反应活性。

The new images hint at an inner ring about half the diameter of the main ring, and so the actual clear "eye" region is smaller than it appeared in earlier low-resolution images.

新图像显示，有一个内环大约是主环直径的一半，因此实际上纯粹的风眼区比以前低分辨率图像中所显示的更小。

Although there are a number of preprinted wristbands on the market, you can order custom wristbands with the name of your company or event.

虽然目前市场已经有一些预先印刷好的手环带，你可以订购印制贵公司的名称或活动内容的客制化手环带。

There is a common sense for banking risk management, that is, effect of risk management depends on the way how it deals with the riskiest point, which has became the operational risk.

在银行风险管理过程中，有一个基本的共识：风险管理的效果取决于最为薄弱的一环，而操作风险正是银行风险管理链条中最脆弱的一环。

This research applies the micro forming process with other mass production techniques to construct the key components of the micro/meso gear transmission.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
