节约

It is possible that taking some actions for increasing stomatic resistance and preventing transpiration could save water and improve photosynthesis and yield as well.

实施提高气孔阻力并抑制蒸腾的措施，既节约水分，又促进光合作用，可提高作物WUE，增加产量。

A portable photosynthesis system made by PPSYSTEM Ltd. was used to study the photosynthetic properties of 3 cultivarsof Rubus idaeus under the field conditions. The results indicated that the individual leave net photosynthetic rates had 2 peaks during a day,an obvious photosynthetic midday slump was observed in A,there was a significant difference in midday depression among the 3 cultivars;evaporation rates of B and C had 2 peaks during a day,while A had 1 peak,and an obvious midday slump was observed in B and C;Stomatic conductance is the key factor of midday slump;Compared with B and C,A had a higher water using efficiency,which will consume less soil water.

利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统，对3个树莓品种的光合特性进行了比较研究，结果表明树莓叶片光合速率日变化呈双峰曲线，A品种&日中低落&现象明显，B、C品种不甚明显；B、C品种的蒸腾速率日变化曲线基本上为双峰型，日变化过程中的&午休&现象非常明显，而A品种为单峰型，日变化过程中的&午休&现象不甚明显；此外，叶片气孔导度与叶片光合速率的日变化趋势基本一致，呈平行变化趋势，说明气孔导度是影响光合速率的直接因子；较B、C品种而言，A品种具有较高的水分利用效率，说明其更能节约并有效地利用土壤水分。

The algorithm can delete the subsequential sets using the weight and generate new candidate sequential sets using the infrequent sequential sets in the knowledge database. It needn't visit the old database again and again, so it can avoid the problem that candidate sequential sets are very large, and can decrease the run time and memory spaces. It improves the algorithm performance greatly.

该算法利用权值来归约子序列集和利用知识数据库中保留的最小非大序列集产生新的候选序列集，避免了重复遍历原始信息库而造成数据量太大的问题，从而缩短程序运行时间和节约数据存储空间，较好地改进了算法性能。

As a type of electric propulsion, arcjet has been the highlight of investigation and application because of its high thrust density, high ratio of thrust and power, preferable specific impulse, better system successiveness and reliability.

水是空间站和一切有人参与的空间探索的必备资源，也是其它星球目前唯一可以直接使用的资源，如果以水作为推进剂，不仅能够解决推进剂在空间的自身供应问题，还可以利用载人航天中的废水，并与其他和水相关的系统共享贮存系统，从而节约成本和空间。

The recent processes in the domestic sulphonation units are introduced which concern heat energy recovery, utilizing SO3 from sulfuric acid unit and replacing ESP with fiber precipitator.

介绍了近年来国内磺化装置在热能回收、采用硫酸装置吸收SO_3气体、用布林克多芯纤维除雾器取代静电除雾器处理磺化尾气诸方面所作的努力和工艺流程，对建设资源节约、环境友好型的新装置及老装置改造有借鉴作用。

The Council of Chalcedon has accepted the synodical letters of the blessed Cyril, pastor of the church in Alexandria, to Nestorius and to the Orientals, as being well-suited to refuting Nestorius's mad folly and to providing an interpretation for those who in their religious zeal might desire understanding of the saving creed.

安理会的卡尔西已经接受了synodical来信得天独厚的Cyril ，牧师教会在亚历山德里亚，以涅斯多留和东方人，是非常适合批驳涅斯多留的疯狂愚蠢，并提供了一个解释这些谁在他们的宗教热情可能渴望了解节约的信条。
