Thesystem development to Delphi7.0 front end took the development kit,2,000 has carried on the development practice take SQL Server as thebackstage database and the ADO database visit technology, this systemrealized under the onstage processing function visitor registration,the registration revised, prearranges processing, the visitor tradesthe room, the visitor continues, the visitor returns a house, thevisitor ties the account guest room operation and the inquiry service,manager inquires, function and so on guest room establishment, userand jurisdiction, system maintenance.

系统开发以Delphi7.0作为前端开发工具，以SQL Server 2000为后台数据库和ADO数据库访问技术进行了开发实践，该系统实现了前台处理功能下的客人登记、登记修改、预定处理、客人换房、客人续住、客人退房、客人结账客房操作及查询业务、经理查询、客房设置、用户与权限、系统维护等功能。

We suggest that the CPO of amphibole in retrograded eclogites is probably formed by rigid body rotation and dissolution-precipitation creep of elongate amphibole grains in a less viscous matrix of symplectite.

结合光学显微特征观察，本文认为退变质榴辉岩中的角闪石 CPO 主要受其显著的长柱状和针状结晶习性控制，其形成机制为差异应力条件下的溶解－沉淀定向生长，可能伴随有早期的角闪石微晶的刚性旋转变形。

Lower Cretaceous belong to retrograding sedimentary sequence of tide-flat-carbonate platform facies,and have good hydrocarbon source rock and reservoir rock but no good cap rock.

下白垩统属退积的潮坪—碳酸盐岩台地沉积序列，生、储油层发育，但盖层发育相对较差，有可能在靠近改则—尼玛断裂带附近形成一些与逆冲断层有关的小型油气藏。

Different shrubberies have different effect on soil carbon management index.

结果表明，侵蚀环境下的坡耕地由于人为干扰，土壤碳库含量偏低，退耕营造柠条林可以显著增加土壤碳库各组分含量，并随恢复年限呈显著线性关系，25 a时TOC、LOC和NLOC分别较坡耕地增加271%、144%和204%，仅为侧柏林的32%、30%和29%，碳库指数和碳库管理指数较坡耕地明显增加，增幅分别达到144%和108%，仅为侧柏林的28%和43%；不同灌木林对土壤碳库管理的改善作用不同，恢复年限相同的沙棘林土壤碳库组分含量和管理指数明显高于柠条林，坡耕地营造灌木林后土壤经营和管理水平得到了显著改善，土壤系统向着良性方向转变。

At present, wetland restoration is a main method to renew the ecological function of the wetland ecosystem, and the Eco-economic benefit is focused on.The paper analyzes and valuates the ecosystem service of Dongting Lake wetland, and discusses its change on the background of wetland restoration. Based on this, the project of Ecological function regionalization is put forward.

本文以洞庭湖湿地为研究区域，对该地区内的生态系统服务功能进行了分析和价值估算；并探讨在退田还湖背景下，洞庭湖湿地生态系统的生态服务功能的变化；在此基础上，提出生态区划方案。

Another time, I was about to step off the curb but pulled back when a speeding cab whooshed past me.

还有一次，我正要走下路缘，但一辆汽车快速驶来时，我退了回去。

Two cylinders drive the tipping unit, loading the bars; one asynchronous motor drives chain motion mechanism, implementing the feed and back off movement of bars; bar lifting movement in the process of chamfering and blanking movement after machining are carried out by another two cylinders; one asynchronous motor rotates the bar and one cylinder swings the wheel head when grinding; the feeding of the wheel head is accomp...

它通过控制两套汽缸驱动翻爪完成上料，一台异步电动机驱动链条式多轮运动机构完成磨削前的进料和磨削后的退料，两套汽缸完成磨削倒角加工时的预料和加工完成后的落料，一台异步电机在磨削加工时驱动棒料旋转，一个汽缸驱动磨头在加工时摆动，一台步进电机驱动磨头实现磨削进给，两套汽缸驱动翻爪完成下料，而磨头是用一台异步电机驱动砂轮旋转的机构，并给出了控制系统原理图及程序流程图，解决了控制器输入点数相对不足的技术问题。

That still in the barrel, creating process variables that may influencethe next shot.

回退的料的温度和压力可能与仍在丝杠内的不同，造成工艺参数的变化从而影响下一次的注射。

The returning material may be of a temperature or pressure different than that still in the barrel, creating process variables that may influence the next shot.

回退的料的温度和压力可能与仍在丝杠内的不同，造成工艺参数的变化从而影响下一次的注射。

We are slowly working toward building a bridge—not a wall, so that when we reach out to each other, we do not find a barrier we cannot penetrate and recoil from the coldness of the stone or retreat from the stranger on the other side.

我们慢慢试着在彼此间建一座桥而不是墙，这样我们可以相互了解，我们之间再没有过不去的坎儿，学会了在冷酷的墙下迎难而上或者从对面的未知中退出来。

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。
