In the second part, we firstly give the definitions of the double inverse limit and some dynamical properties related, then we use the above way to study the dynamical relations between the systems and lim{X, f^g},σ_f^σ_g...

在论文的第二部分，我们模仿逆极限{X，f的定义，提出了双重逆极限{X，f^g的概念，并针对X上的两个交换的自映射f和g，类似定义了系统上的一些动力性质，并证明了系统与系统(？{X，f^g}，σf^σ_g之间在这些动力性质上的一些相关结果。

Skull x-ray film showed expansile osteolytic lesion over the left parietal area and the chest x-ray increased reticulonodular infiltration in both lung fields. There was no abnormal finding in the long bone survey or abdominal sonography.

之后的检查结果包括：头部X光检查发现在左侧顶骨处有扩张性的蚀骨病灶；胸部X光摄影显示在二侧肺野均有网状结节状浸润增加的情形；长骨X光检查与腹部超音波扫描皆无异常。

Xist and Tsix are imprinted in the extraembryonic tissues of mouse embryos so that they are expressed from the paternal and maternal X, respectively, resulting in the preferential inactivation of the paternal X.

Xist和Tsix在小鼠胚胎的胚外组织中是印迹的，Xist在父本X染色体上表达而Tsix在母本X染色体上表达，导致父本X染色体的优先失活。

Lighting setup are two KZ fixtures with each 8 x 54 W T5 (2 x Fili Purple / 2 x Narva blue / 12 x KZ New Generation).

KZ灯架， 8 x 54W T5HO (2斐济蓝/ 2 Narva蓝/ 12 KZ混合形新品)至少到现在，我还满意，没有想重用我旧缸的HQI

Lighting setup are two KZ fixtures with each 8 x 54 W T5 (2 x Fili Purple / 2 x Narva blue / 12 x KZ New Generation). So far I do not miss the shimmer of the HQI to much older picture

KZ灯架， 8 x 54W T5HO (2斐济蓝/ 2 Narva蓝/ 12 KZ混合形新品)至少到现在，我还满意，没有想重用我旧缸的HQI

It reformed the coventional grazing incidence method of reflecting x ray, and made it possible to reflect x ray in normal incidence way.

它从根本上改变了传统的掠入射反射x光的方法，使正入射反射x光成为可能，并极大的促进了x光学的发展。

The electrical transport properties in the zero magnetic field about the (1 -x) La2/3Ca1/3MnO3/xZn(NO3)2 system and the (1-x)La2/3Ca1/3MnO3/xFe(NO3)3 system have been given. We compare these results in three systems and simply give the qualitative indicant.

研究了(1-x)La_2/3Ca_1/3MnO_3 / xZn(NO_3)_2体系和(1-x)La_2/3Ca_1/3MnO_3 / xFe(NO_3)_3体系的零场电输运行为，并与(1-x)La_2/3Ca_1/3MnO_3 / xCu(NO_3)_2体系进行了比较，并简单定性解释了比较结果。

A weak inverse of S is an element x ∈ S such that x = xax, denoted by W the set of weak inverse s of a.

如果存在x∈S，使得x=xax，则称x为a的一个弱逆。

The main content of this paper as follows: The acidic strength, reaction temperature, reaction time of Chlorine-aluminate Ionic Liquids with different structure of cation on the activity of transalkylation of MN with TeMB and the selectivity of 2,6-DMN were studied. The optimum reaction condition was obtained: the molar fraction of AlCl_3 is 0.71, molar ratio of 2-MN and TeMB is 1, the amount of ionic liquid is 32wt%, reaction temperature is 20℃and reaction time is 8h using X-xAlCl_3 and X-xAlCl_3 as catalysts; the optimum reaction time is shortened 6h using Et_3NHCl-xAlCl_3 as catalyst.

本文主要研究了以下内容：分别考察了不同阳离子结构的氯铝酸盐类离子液体的酸强度、反应温度、反应时间等因素对MN和TeMB转移烷基化的催化反应活性和2，6-DMN选择性的影响，优化得到适宜的反应条件为：以X-xAlCl_3和X-xAlCl_3为催化剂时，AlCl_3的摩尔分数x=0.71，2-MN和TeMB摩尔比为1∶1，离子液体用量为32wt％，反应温度为20℃，反应时间为8h；以Et_3NHCl-xAlCl_3为催化剂时，反应时间缩短到6h。
