Pristine Li-Al LDHs are synthesized by hydrothermal process in different reaction conditions by varying the aging time for 1 and 24 hours. Both the Li-Al layered double hydroxides (abbreviated as Li-Al LDH1 and Li-Al LDH24 for aging time 1 hour and 24 hours, respectively) were modified by using sulphanilic acid sodium salt hydrate, modified agent to form modified Li-Al LDH1-SAS and Li-Al LDH24-SAS. The morphology of the pristine layered double hydroxides are investigated by using wide angle X-rays diffraction, scanning electron microscopy and particle size analyzer which indicates that the crystallinity and aspect ratio is increased with increasing the aging time from 1 hour to 24 hours. The particle size of Li-Al LDH24 and Li-Al LDH1 are found to be ~1000 nm and ~250 nm, respectively. Both the pristine and modified LDHs are characterized by XRD, FTIR spectra and thermogravimetric analysis.

本研究目的在於改变长晶时间的长短，合成出同径大小的Li-Al LDHs，再经由改质剂sulphanilic acid sodium salt hydrate将Li-Al LDHs无机层材表面有机官能化制备出改质型Li-Al LDHs-SAS，於是进一步藉由扫描式电子显微镜、射径仪和穿透式电子显微镜等仪器分别观察LDHs改质前和改质后其主层结构型态上的变化；从中可以发现Li-Al LDHs随著长晶时间的增加其径有随之增大的趋势，但经有机化改质后其径会由於改质环境的影响明显低许多，针对此现象本实验将未改质和改质后之Li-Al人工无机层材制备成复材进一步探讨其在热性质和难燃特性上的为表现。

Methods The clinical data of 12 patients from Mar 1993 to Jun 2008 with retrocaval ureter were retrospectively analyzed. All the 12 cases were correctly diagnosed preoperatively via the combination of imaging examinations, such as ultrasonography intravenous pyelography、retrograde pyelography、CT or magnetic resonance urography. Ten patients received conventional open surgery and two received retroperitoneal laparoscopic ureteral replacement and ureteroplasty.

The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型，多数台地边缘鲕粒滩形成时水体相对较深，未经大气淡水和混合水的成岩改造，储集性能较差，局部鲕粒滩形成时水体较浅，在经过大气淡水和混合水的成岩作用改造后，白云石化好，可形成储集性能极好的储集体；台地内点滩白云石化较好，储集性能也较好，但分布狭窄，厚度较薄，无规律可寻。
