It follows that the de-protonic reaction of hydroxide group for PVA had taken place in above solution, and the coordination group for deprotonic oxygen of PVA had produced more. These ligands interact with some Fe3+ of ferric hydroxide while the ferric hydroxide in new emergence is forming,causing the formation of Fe-PVA coordination polymer-the composition of the reddish brown resinoid substance.

推定PVA部分羟基在上述条件下发生脱质子反应而提供L-配位体，Fe盐水解生成初生Fe3的Fe3+，它既有空轨道，又有较强的正电场，故能吸引PVA高分子配位体L-上的氧而形成O→Fe配位键，从而发生L-与Fe3+离子间的交联反应，生成多核Fe-PVA配位聚合物而析出红棕色树胶状物。

Completely different crystal structures and morphology were shown in the meltdrawn films of two kinds of tacticity of sPP. A continuous conformational transform from the 〓 into the of sPP was induced by further stretching. While the zigzag conformation can retransform back to helical 〓 one after annealing above 80℃, the mechanism of conformation transform has been introduced.

Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

一般来说通常需要将金属、导电高分子、或石墨等导电材料涂布於毛细管样品出口尖端，外加第二组电压於导电尖端以提供电喷洒时所需要的电场，但如何将导电材料稳定地涂布於矽氧材质的尖端表面一直是此界面探讨的主题之一。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
