Triatomic molecules We studied the interaction of linear triatomic molecules CO〓 and CS〓 with the intense femtosecond laser field at different intensities and polarization states. The kinetic energy of the C ion is much less than that of the O ion at the same charge states indicating that the Coulomb explosion is a concerted process, that is, the two C=O broke simultaneously.

三原子分子研究了不同强度的不同偏振的飞秒强激光场和线性三原子分子CO〓和CS〓的相互作用。C离子的平动能要远小于同电荷数的O离子的平动能，表明库仑爆炸是一个协同过程，两个C=O键同时断裂。

Ti〓 ion and triethanolamine may be combined together to form a complex which is dissolved in water at normal temperature.The hydrolysis of Ti〓 ion is controlled by the formation of the complex.

The factors of temperature and humidity influenced on film thickness and order of layer were studied, in which pulling speed and pulling times were also included. It showed that the thickness of single dip-coating film reached 0.23 μm ~ 0.625 μm, and the degree of order of surface layer were still holding much higher.b Adopting calcined or uncalcined mesoporous silica membrane as matrix, nano zirconia particles were assembled through ion exchange method and ion-template exchange method.

结果表明，单次提拉膜膜厚0.23μm～0.625μm、8次提拉后表层膜仍有一定的有序性； b以自制的介孔氧化硅煅烧/未煅烧厚膜样为基体，采用离子交换法/离子模板交换法组装锆氧纳米粒子，选用DSC-TG、FT-IR、Uv-vis、SAXRD等对不同组装方法、锆源浓度、pH值等组装条件下ZrO_2/介孔氧化硅厚膜组装效果进行评价。

It was found that the central metal ion is located at the symmetric center of the molecule. Four oxygen atoms from two H2O molecules and two 〔C6H4(CO2)2〕2- groups are coordinated with copper ion to form a similar planar square coordination configuration. There is one only unidentate coordination bond between O(1) in 〔C6H4(CO2)2〕2- and Cu2+.

结构分析发现，中心金属离子位于分子的对称中心位置，铜离子与来自2个水分子和2个邻苯二甲酸根中的4个氧原子形成近似正方形平面配位，邻苯二甲酸根是以1个O(1)与Cu2+离子形成单齿配体，O(2)和Cu2+之间没有形成配位键。

Membrane scaling is caused by the deposition of unsoluble salts as feedwater is converted to brine. In this process the ion concentration of calcium, magnesium and so on increases greatly which will lead to that the ion product of sparingly soluble salts exceeds its solubility product, and the unsoluble salts deposite on the surface of RO membrane to form membrane scaling.

在反渗透海水淡化过程中，由于膜的浓缩作用，浓水中的钙、镁等离子浓度大大增加，从而使难溶盐的离子积大于其溶度积，在反渗透膜表面形成膜垢，影响整个反渗透装置的正常运行，缩短了反渗透膜的使用寿命。

A new style CFOA was proposed in this paper, the compens AT ion circuit elimin AT e the imbalance between the two input in st AT ic condition,the PMOS and NMOS complementary input structure enhance SNR,Simul AT ion with 0.6 CMOS process parameters,result in a high SR as well as bandwidth gain-independence.

本文提出了一种新型的电流反馈形运算放大器，该电路所具有的电压补偿电路克服了以往基于CMOS的CFOA两个输入端静态条件下不平衡的缺点；NMOS与PMOS互补的输入结构提高了电路的信躁比。

There is an addit ion al advantage in using iodide ion in the developer; namely, increased stability of the process

在显影液中采用碘离子可增加本方法的标定性。

If both the molecule to be transported and the ion move in the same direction across the membrane ,the process is calle symport ; if the molecule and the ion move in opposite directions it is called antiport.

如被动运输的分子和离子同向运动，则称为同向转运；若两者反向运动则称谓反向转运。

Fly ash and slag can increase the resistance of concrete to chlorid e ion penetration,and silica fume,metakaolin,rice husk ash and some content s lag can increase significantly the resistance of concrete to chloride ion penetr ation.

粉煤灰和矿渣能提高混凝土的抗氯离子渗透扩散能力，硅粉、偏高岭土、稻壳灰和适当掺量的矿渣能大幅度提高混凝土的抗氯离子渗透扩散能力。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
