Language skills and autonomous learning. this paper, on the basis of about two-year testing, has presented the experiment and analyzed the result in order to promote transformation from the teacher-centered teaching model to a student-centered one, which is pluralized, individualized and initialized.

在历经近两年实践的基础之上，本文总结和分析了试点的结果，以期推进大学英语教学由传统的以教师为中心的单一模式向以学生为中心的多元化、个性化、自主化教学模式方向发展。

We assume that changes of azimuth antenna pointing between subswaths are small enough to guarantee that DC changes much tinier than PRF diversity.

算法假设子带间的方位向天线指向变化足够小，以致由此导致的多普勒中心的变化远小于PRF的差异，从而可以近似认为多普勒中心是随距离连续变化的。

DESIGN: A validated anonymized questionnaire was sent to 401 senior attending gastroenterologists asking for details of their current management of BE, especially histological sampling. Of the 228 respondents, 57 individuals were in the first group to enter the ASPirin Esomeprazole Chemoprevention Trial, and we assessed change in practice in these centers.

设计：将一份确认为匿名的调查问卷发寄给401位主治胃肠病的资深专家，向他们了解目前Barrett's食管治疗的详细情况，尤其是组织学采样。228位受访者中有57位（均来自于不同的试验中心）被分在第一组，参加阿司匹林和奥美拉唑化学预防的试验，我们对这些试验中心在医疗实践中的变化加以评估。

Prior to cell division it replicates, and the sister centrioles move to opposite ends of the cell to lie within the spindle-organizing structure, the centrosome.

它在细胞分裂之前复制，其中一个中心粒移向细胞的另一端，组织纺锤体和中心体。

The calculating results indicate that surrounding rock initial stress has an obvious influence on interior force of invert center, interior force increases with the vertical force increasing in both side of invert center, and decrease with horizontal force increasing in interior side , unchangeable in outer ...

计算结果表明，围岩初始应力场对仰拱受力有明显影响，随着竖向压力的增大，仰拱中心的内、外侧应力均增大；随着水平压力的增大，仰拱中心内侧应力减小、外侧应力基本不变；减小复合衬砌结构中初期支护厚度以及变刚性接头为柔性接头均会改善仰拱受力。

By Krugman s core-periphery model,this paper analyses in detail the process of American Manufacturing transmission from North-east and the coastal areas of Mid-Pacific to the Midwest.

本文通过引述Krugman的中心-外围区域模型，详细分析了美国早期制造业中心从位于东北部、大西洋中部沿海地区向中西部地区转移的条件、过程。

This paper summarizes pluton growing pattern and formation process into central, biacentrol, lateral, irregular and multi-central growth. The volume accretion may be explicated by the growing curves.

岩体的生长方式、形成过程可概括为中心式、偏心式、侧向式、不规则式、中心多点式，生长量特点可以用生长曲线表述。

In-situ monitoring gave the following results: 1 a tension stress zone occurred at the bottom of reinforced rock mass which indicated that the role of rock bolting was remarkable; 2 stress concentration at surrounding rock of main shaft was gradually transferred from shaft wall to complete rock mass far from shaft center; 3 vertical displacement was gradually smaller from up to bottom and from center to outside of the reinforced loose rock mass.

首先，建立了主溜井三维有限元计算模型，模拟了主溜井围岩的塌落破坏过程和加固后的加固体的稳定性及变形特性；同时，还采用多点位移计等对加固体的稳定性进行了实地监测。计算结果表明：网棚锚注加固体的纵剖面上的压力和位移规律是①加固体下部局部出现拉应力区，表明锚杆的使用是合理的；②加固体内的应力由塌落中心向周围围岩过渡，应力越来越大，最终将荷载传至围岩中；③从下到上下沉逐渐减小；④从加固体中心到周围下沉位移逐渐减小，且近似一条抛物线。

Meyer earlied childhood to hold facility in recent years by speech center function gradually to recreational center transfer, same this also brought another greater opportunity for semiconductor industry.

迈耶还提到了手持行动措施近年由语音中心性能逐渐向娱乐中心的过渡，同样这也为半导体业带来了另一个更大的机缘。

Always focus on customers can not be only a slogan or service purpose stuck on the wall, instead, it shall be a concrete actual action and a kind of feeling brought to customers, such as make tea for customers quickly; sincerely apologize to customers; take initiative in solving problems for customers; actively send a card or make telephone calls to customers on their birthday; during waiting, prepare newspapers and magazines for customers to pass time, etc

始终以客户为中心不能只是一句口号或是贴在墙上的服务宗旨。始终以客户为中心应是一种具体的实际行动和带给客户的一种感受，如：快速的为客户倒上一杯水；真诚地向客户表示歉意；主动地帮助客户解决问题；在客户生日时主动寄上一张贺卡或打电话问候；在客户等候时为客户准备书刊杂志以消磨时间等。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
