PDA was often combined with all kinds of intracardial malformation ,preoperational diagnosis and interoperative exploration are extremely helpful for diagnosis . A strict control of indication and the improvement of CPB technique are significant to lower the death rate and postoperative complication . Suturing PDA through incision in pulmonary artery under CPB is the main treatment for PDA, using Foley catheter to block arterial canal flow helps to fully expose the operating field 、shorten CPB duration and lower the complications of lungs and brain .

各种心内畸形经常合并PDA，术前诊断及术中探查，意义重大；严格掌握手术指征和提高CPB技术，对降低手术死亡率及术后并发症具有重要意义；经肺动脉切口缝闭PDA是CPB下处理PDA的主要方法，术中应用 Foley导尿管阻断动脉导管血流，有利于术野显露、缩短CPB时间，可降低肺部、脑部并发症。

In this paper,the system is specified in EFSM model.The concept of invertibility is introduced and used to optimize the transition executability analysis method,so that shorter test sequences can be generated and smaller space is needed to generate the TEA tree.

文中以EFSM为协议的描述模型，引入了逆向判定性的概念，并利用这一概念对转换可执行性分析方法进行了改进，缩短了生成的测试序列的长度，并且减小了所需的TEA树扩展空间。

"The Tendering and Bidding Law of the People ' s Republic of China" lead the competition mechanism of bid invitation and tender into the investment financing and public purchase of our country. This mechanism has changed our country ' s traditional direct purchase and administration way, broken the place and department protectionism, offered an equally competition environment and effective legal guarantee for the bid invitation and tender, assured the quality of project, improved the economic benefit, advanced the technique and manage level, ensured the quality of construction、 shorten the time for a project and promoted the socialist market economy system setting –up and perfection.

《中华人民共和国招标投标法》把招标投标的竞争机制引入我国投融资和公共采购领域，改变了我国传统的直接采购和行政分配方式，打破了地方和部门保护主义，为企业的招标投标活动提供了平等的竞争环境和有效的法律保障，保证了项目质量提高了经济效益，促进了技术进步和管理水平的提高，保证了工程质量、缩短工期，促进了社会主义建设市场经济体制的建立和完善。

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。

According to experts' prediction, air temperature will rise 1~4℃, due to warming climate, which makes the growing period of single cropping rice and early rice in China shorten.
