It is indicated that horizontal sidetrack technology has a bright future,so one should make the technology of a efficient,cheap become a complete set and routine techniques.The one object of studies is enhancing effects and reducing costs,and the research method is multidisciplinary team work and introducing various new technique.

指出，侧钻水平井有极广阔的应用前景，因此应使这项技术成为一种高效的、经济的、配套的常规技术，研究的目标是增强效果和降低成本，研究的方法是多学科联合攻关和引入各种新技术。

Not long after, discoveries of gold in the Klondike and the Yukon led to an increase in gold reserves, which had the same net effect on liquidity as moving to a silver standard – the US economy eventually reflated.

不久以后，在克朗代克河与育空河一带发现了金矿，导致黄金储备增加，从而货币供应量也增加了。这与布莱恩倡议的银本位制效果相同，美国经济最终凭此走出了通货紧缩。

The most frequent fallacy by far today, the fallacy that emerges again and again in nearly every conversation that touches on economic affairs, the error of a thousand political speeches, the central sophism of the new economics, is to concentrate on the 11 short-run effects of policies on special groups and to ignore or belittle the long-run effects on the community as a whole.

当 今最为盛行的那些谬误，在涉及经济事务的每次探讨中反反复复暴露出来的那些谬误，无数政治演讲中的错误，以及新经济学中核心的似是而非的论点，便是只重视政策对于特殊集团产生的短期效果，而忽略或淡化其对整个社会的长远影响。

The form and space of the sprinkler head arrangement were optimized by taking full advantage of work system pressure under the criterion, in order to realize the safe, practical and economical effect.

自动喷水灭火系统设计中的关键工作是喷头的设置，文章探讨了在满足规范要求的前提下，充分利用系统工作压力对喷头的布置形式和间距进行优化，以达到安全、实用、经济的效果。

It was a damp squib. Global financial turmoil should encourage it to produce some fireworks.

政策没有达到预期的效果，也许全球经济动荡会让这个话题引起人们的一些争辩。

In this paper a country economy forecast model is built using RBF network, take data between 1991 and 2006 as stylebook data, and use a software called Matlab to check the effect of the model, find the error of forecast is lower than other methods.

本文利用RBF网络建立国民经济预测模型，采用1991-2006年的数据作为样本数据，运用MATLAB对所建立模型的效果进行检测，对经济总量指标预测的误差程度较低。

This paper gave the detailed reviews on previousresearch results on subdrainage home and abroad,studied the effect and mecha-nism of subdrainage facilities on drainage,waterlogging reduction,salt removeas well as nitrogen fertilizer application under subdrainage conditions by use oflysimeter experiments and field trials.Numerical modelling on water movementin heterogeneons multilayered soils as well as the optimization layout of spacingsand depths of PVC subdrain was also investigated in this paper by numerical sim-ulations.

本文在论述国内外暗管排水研究进展的基础上，采用蒸渗仪控制试验，田间试验和数学模型数值计算相结合的方法，对塑料暗管的排水、降渍、除盐效果及其机理和塑料暗管排降条件下小麦的N肥运筹进行了深入研究，并对排降条件下试区非均质分层土壤水分运动的数值模拟和塑料暗管埋深和间距的经济优化布局模式进行了探讨。
