Notably, compounds 12–14 can be described as a 3D open–framework with nano–channels, compound 15 can be described as a 3D open–framework with double helical channels, while compound 16 can be described as a 3D heterochiral coordination polymer with double helical channels, which can be obtained by spontaneous resolution from the racemic phosphonic acid.X–ray powder diffraction analysis shows that compound 16 is a pure phase. Surface photovoltage spectroscopy of compound 16 indicates that it possesses positive SPV response in the range of 300–600 nm and shows p–type semiconductor characteristic.

值得注意的是，化合物12-14为具有一维纳米孔道结构的三维开放骨架结构，化合物15是具有双螺旋孔道的三维开放骨架结构，而化合物16是外消旋的有机膦酸配体通过自发拆分而形成的具有双螺旋孔道的多手性三维开放骨架结构。X-射线粉末衍射分析表明化合物16为纯相；化合物16的表面光电压光谱分析中，在300-600nm范围内有3个正的光(来源：ABC论文12网www.abclunwen.com)伏响应带，表明它具有p型半导体的特征；化合物16的诱导表面光电压谱进一步确定它的p型半导体的特征；磁性研究表明，化合物16中两Mn原子之间存在弱的反铁磁相互作用。

The variables in controlling the flow of microfluids are voltage and time. This study adopted the method of fast measurements、so time taken for applying voltage did not exceed ten minutes. If voltage is not carefully controlled、the microchannel may be damaged at the particle flow. During measurement、a buffer fluid with a concentration of 0.1 M was used、the current was sufficient to propel the magnetic particles through the microchannel without damage from excessive voltage. The maximal amount of microfluid particles at the junction of the separation and injection channels was obtained with a time of 5 mintures and voltage of 200V.

藉由改变不同的电压和时间来观察颗粒在微流体中的移动情形，由於这个研究是以快速检测为原则，所以将时间控制在10分钟之内；在电压的控制上面如果电压太大的话将会对微流体的管道造成损伤，降低微流体装置的寿命，并且也有可能会对里面的颗粒造成影响，所以缓冲液的浓度使用比较大的0.1 M，这样所产生的电流将足以推动磁性颗粒并且电压不会太大也不会造成管壁的伤害。

The CoFe2O4/TiO2 magnetic nano-photocatalysts has fairly good magnetic property. The X-ray diffraction, transmission electron microscopy and ultraviolet-visible technique were used to analyze the phase structure, size and spectrum response scope of the samples. The XRD indicated the anatase TiO2 was formed when TCF modified by plasma. The size of CoFe2O4 particles was about 20 nm. The diameter of CoFe2O4/TiO2 particles is in the range of 30~40 nm. So the shell of TiO2 enwraps closely around the core and the thickness is in the range of 10~20 nm.

运用VSM技术对样品磁性能进行研究，结果表明：等离子体修饰后的复合材料仍具有较高的饱和磁化强度，可在外加磁场作用下实现催化剂在水中的分离与回收；样品的XRD、TEM和UV-Vis分析测试结果表明：等离子体修饰后的复合材料有锐钛矿型TiO2存在；TEM谱图显示磁核CoFe2O4的平均粒径约为20 nm，TCF复合粒子的粒径约为30~40 nm，TiO2包覆层的厚度为10~20 nm。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
