New contributions of this work are as follows:(1). Preparation of Spherical MgCl_2-Supported Late-Transition Metal Catalysts for Ethylene PolymerizationFacile and effective immobilization of late-transition metal catalysts. 2,3-bis-(2,6-diisopropylphenyl) butane diimine nickel dibromide (1) and 2,6-bis-[1-(2,4,6-trimethylphenylimino)ethyl]pyridine iron dichloride (2), for ethylene polymerization has been achieved, using spherical MgCl_2 supports obtained by thermal dealcoholization of MgCl_2·2.56C_2H_5OH, and the effects of dealcoholization temperature on supported late-transition metal catalysts and the properties of resultant polymers were studied, the results indicated that:1.Supports with appropriate mechanical strength, high surface area and high porosity could be prepared by thermal dealcoholization of spherical MgCl_2·2.56C_2H_5OH supports; 2.BET, XRD, IR, SEM, GPC and DSC analyses indicate that the activities of the supported late-transition metal catalysts and the properties of resultant polymers are strongly dependent on the dealcoholization temperature.

本工作的新贡献如下：(1)、球形氯化镁负载后过渡金属催化荆催化乙烯聚合本文将配合物2，3-双(2，6-二异丙基苯亚胺)丁烷二溴化镍(1)和配合物2，6-二[1-(2，4，6-三甲基苯亚胺)乙基]吡啶二氯化铁(2)分别直接负载于经不同热脱醇温度处理的球形氯化镁载体上，研究了氯化镁载体的脱醇温度对负载化后过渡金属催化剂及其聚合物的影响，研究表明：1、通过对球形MgCl_2·2.56C_2H_5OH载体进行热脱醇处理，可以获得合适机械强度、较高比表面积和较高孔隙度的球形氯化镁载体；2、BET，XRD，IR，SEM，GPC和DSC研究表明，脱醇温度极大地影响负载后过渡金属催化剂的活性和聚合物的性能。

The tectonic evolution of southern Junggar basin can be classified into seven stages: stage of intracontinental rift from middle Periman to late Late Carboniferous; stage of weak extension and peneplane from late Permian to early Triassic; stable depression stage in middle-late Triassic; maximal basin formation phase in the setting of weak extension in early-middle Jurassic; inactive depressed basin formation phase in thrust setting in middle-late Jurassic; stable depression stage in Cretaceous and Eogene; foreland depressed basin formation phase in thrust setting in Neocene and Quaternary.

准噶尔盆地南缘晚石炭世以来盆地构造演化可划分为七个演化阶段：晚石炭世—中二叠世陆内裂谷作用阶段；晚二叠世到早三叠世处于弱伸展-稳定坳陷作用阶段；中、晚三叠世准平原化作用阶段；早、中侏罗世为弱伸展背景下广盆形成阶段；中、晚侏罗世冲断背景下的坳陷盆地形成阶段；白垩纪到古近纪弱伸展背景下的稳定坳陷盆地形成阶段；新近纪—第四纪为冲断背景下的前陆坳陷盆地形成阶段。

The change of REE composition between the upper and lower samples from Hongcan well implied the tectonic setting and property of the sediment provenance in Zoige Basin were altered obviously between late-period of Middle Triassic and mid-period or late-period of Late Triassic. This change was probably due to elevation and erosion of the matured continental crust on the east of Zoige Basin, and lots of clastic materials transported into the basin in late-period of Late Triassic.
