All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

通过研究配合物的单晶结构，我们发现叔丁基取代的不对称N_2O_2配体与ZrCl_4反应生成的锆配合物为氧桥和羟基桥连接的双核锆配合物，中间过程涉及单核锆配合物中氯原子部分水解，并得到氯原子部分水解的双核锆配合物和全部水(来源：8e6eAB67C论文网www.abclunwen.com)解的四核锆配合物的晶体结构，在晶体培养过程中发现双核锆配合物能够以手性自发拆分结晶析出。

Methods On same oral therapy condition,the patients in control groupwere given commmon thoracocentesis on twice a week,the patients in experimental groupwere treated by thoracic tube intubation with veinal catheter.After drainage within3days,the pleural cavity of the paˉtients in group E were injected with the compound of sodium hyaluranate,sodium carboxymethylcellulose and butyltriˉamcinolone.The patients of two groups were examined by X-ray after6months.According to the database of normal crowd chest X-ray photograph,the area of patient's photograph was drawn.The value of average gray scale in the area was gathered by image analysis system and to be compared with the value of normal side,so the gray ratio was got after correction.

在口服给药条件一致的前提下，对照组患者沿用常规每周2次间断抽液的方法；实验组采用静脉留置针持续引流的方法，3日内将胸液引流尽后注入由透明质酸钠、羧甲基纤维及丁基去炎松组成的可吸收生物活性凝胶。6个月后行胸片检查，图像分析系统根据正常人群胸片同侧拟合区域采集平均灰度值并与健侧相比，经校正后得灰度比。
