无线传感器网络所具有的能耗有限性和节点资源有限性要求在任务调度过程中进行实时数据交换时要尽量减少传感器节点的功耗，而数据融合能有效减少网络内的数据传输量，减少能源的消耗，并尽可能地挖掘传感器节点的处理能力。

X6 3?,large specific surface area and adsorbent capacity However,most molecules and hydrated ions can not enter the aperture pass because of their size over the aperture diameter of palygorslote except less simple ones Furthermore,Palygorskite adsorbs water molecule choosingly In most cases the absorbing of palygorskite is by its outside surface that works in the form of colloid and ion exchange other than i...

但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。

After extraction by ethanol and purification by cationic ion-exchange column, a method of using reversed-phase high-performance liquid chromatography and precolumn derivatization with o-phthalaldehyde and 9-fiuorenylmethylchloroformate is employed for determination of free amino acids in tobacco . This method assures that amino acids with amino and imino groups can be determined simultaneously. The results of duplication experiment and recovery experiment are acceptable.

本试验用乙醇提取烟叶中的游离氨基酸，并用阳离子交换树脂纯化，再用邻苯二甲醛、氯甲酸芴甲酯联合柱前衍生、反相高效液相色谱分析测定了烟叶中的游离氨基酸，该方法能同时测定烟叶中的带氨基和亚氨基基团的氨基酸，并且分析方法的重现性和回收率均令人满意。

The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介质由交换耦合的软磁层与硬磁层构成，它是通过软磁层与硬磁层的磁矩在磁化反转过程中的非一致转动来达到降低矫顽力的效果，而无外场时热反转仍为一致转动，因而能保持较高的热稳定性。

Each individual becomes more expert in his own peculiar branch, more work is done upon the whole, and the quantity of science is considerably increased by it.

每一个人都能用自己的大量物品交换他人的大量物品，或者说按照用他们的大量物品表示的价。

As part of a System-Wide Information Management project, the FAA sought a Web-enabled solution that enables users to add data to the static SUA and ATCAA repository and communicate status changes to those airspaces to the operational systems in an Aeronautical Information Exchange Model format.

作为广域系统信息管理计划的一部分，FAA一直在寻求一种网络赋能的解决方案，可以使用户向动态的SUA和ATCAA知识库添加数据，并且在航空信息交换模式的标准下，允许这些空域的通信状态发生变化。

Aminobutyric acid in tea was extracted, isolated and determined. Water achieve a better effect than ethanol in extracting γ-aminobutyric acid, and γ-aminobutyric acid content was enhanced by 20%; 732 positive ion resin columns (2.5×50cm) was used to isolate, citric acid and ammonia water were used as elutes, based on pH linear gradient. Results indicated that γ-aminobutyric acid inelute could reach 39%; thin layer scanner could measure the content of γ-aminobutyric acid.

对茶叶中γ-氨基丁酸的提取、分离及检测方法进行了研究，分别采用水和乙醇作为提取溶剂，结果发现用水提取能达到更好的效果，γ-氨基丁酸含量提高20％；同时采用离子交换树脂对γ-氨基丁酸提取液进行分离，提取液上732阳离子树脂柱(2.5 ×50cm)，使用柠檬酸和氨水缓冲液进行pH线性梯度洗脱，洗脱液中γ-氨基丁酸最高浓度达39％；采用薄层扫描仪对γ-氨基丁酸的含量进行检测，研究并确定了检测的条件及参数。

The computed results verify the existence of the three heat and oxygen exchange zones in blast furnace. Charging coke at center can suppress the center coke gasification reaction, improve the strength of center coke and increase the permeability of both gas and liquid.
