It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.

认为要控制好PRD弱凝胶钻开液的性能，流型调节剂PF-VIS的加量是关键；PRD弱凝胶钻开液的粘度随着剪切速率的降低而急剧上升，显示了其优良的井壁携砂带砂性能；PRD弱凝胶钻开液体系具有较好的高温稳定性；PRD弱凝胶钻开液体系在低剪切速率的高粘度，大大高于传统聚合物钻井液，有利于在大斜度井携带岩屑以及防止岩屑床的形成。

UV-Vis spectra before and after the treatment were analyzed. It was showed that the decoloration of direct sky blue during the amplified sunlight with H2O2 photolysis treatment was due to the dye photolysis.

本文首次制备了掺杂氧化还原指示剂靛红的聚吡咯膜修饰电极，研究了聚合条件对所得膜电化学行为的影响，并用XPS，SEM，UV-Vis光谱等手段进行了表征。

The complexing properties of compounds 10a, 10b, 11a and 11b toward alkali metal ions were studied by 〓H NMR titration, ESI-MS, UV-Vis spectra, Fluoresence spectra and liquid-liquid extraction. The results show:(1) the 1:1 complexes were formed.(2) The calix-crown 10a, 11a have a higher selectivity for Na〓 ions, whereas 10b, 11b for K〓 ions.(3) The complexing ability toward alkali metal ions was enhanced when the calix-crown have side arm carbonyl.(3) The coordination of alkali metal ions toward phenoxy, carbonyl and crown ethereal oxygens take place by rotation around the carbon-carbon bond of carbonyl and methylene.

六，用〓H NMR滴定，ESI-MS，UV-Vis，Fluorescence，液-液萃取实验研究了10a，10b，11a和11b对金属离子的配位性质，研究结果表明：1）杯芳烃冠醚衍生物同碱金属离子形成了1：1配合物，化合物10a、11a对Na〓具有较高的配位能力，化合物10b、11b对K〓具有较高的配位能力；2）在杯冠醚环的旁边引入带有羰基氧原子的基团作为侧臂参与配位可以加强对碱金属离子的配位能力；3）金属离子分别同苯酚氧，羰基氧，聚氧醚链氧发生了配位，配位过程中侧链基团涉及到了羰基碳与亚甲基碳的碳碳键的旋转过程。

And 17 were capable of detecting specific metal ions by showing dramatic enhancement of fluorescence. In contrast with 15 and 17, the fluorescence signals of 13 and 14 were inefficiently altered by metal ions. Hence, 15 and 17 were further investigated with detailed 1H-NMR, UV-vis, and fluorescence titrations.

其中，15和17对特定金属离子有明显的侦测能力，混合后萤光强度会大幅增强，但13及14与金属离子混合后，萤光讯号的改变幅度不如15及17的显著，因此我们只对15和17进行详细的1H-NMR、UV-vis及萤光光谱的滴定。

The particle was investigated using TEM, XRD, TG-DTA, X-ray fluorescence spectrometer and UV-Vis spectrophotometer.
