本文的主题是企业信息集成中OPC技术的研究与开发，第三章和第四章主要围绕OPC技术的开发展开讨论。

Chapter Three and Four are the major part of the thesis.

第三章和第四章是本文重点部分。

Such a short span of 10 characters of the four hidden danger: from Ignorance of managers to run businesses, like "blind man on horseback", which is the first danger; rely on the ignorance of the staff, just as "riding a blind horse," This is the second risk involved in the fierce market competition, just as "The deep pool," This is the third risk in the global economic downturn when participating in the fierce market competition, just as "Midnight A deep pool," and this is the fourth dangerous.

这短短十个字隐藏了四个危险：由无知的经理人来经营企业，就如同"盲人骑马"，这是第一个危险；依赖无知的员工，就如同"骑瞎马"，这是第二个危险；参与激烈的市场竞争，就如同"临深池"，这是第三个危险；在全球经济不景气的时候参与激烈的市场竞争，就如同"夜半临深池"，这是第四个危险。

This allowed Ometto to break away at the front and he was able to pull out a commanding lead to win by 7 laps ahead of Simone Zanon in 2nd and Massimo Poldi in 3rd, all driving the Mantua, which in fact took the first 7 positions in the final.

这使Ometto打破在前面，他能够拉了领先赢得了7圈提前西蒙娜Zanon在第2和马西莫波尔蒂在第三，所有驾驶曼图亚，事实上在第一次在7个职位最后。

According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

Tour Itinerary While you are in Cairo, you can enjoy a full two days tour to Luxor, you will be transferred from your hotel at 7 pm transfer to the train station taking 8,20pm train to LuxorDay1 7 Am Pick up from the train station in Luxor and starting guided tour with groupe to see Karnak temple, the greatest example for worship in the history, dedicated to God Amon, his wife Mut and and their son khonsu and then you will check Luxor temple and over night in the hotel in LuxorDay 2 7 a.m. Start guided tour with groupe to see valley of the kings, valley of the queens, temple of the queen Hatshpsute the only pharaonic woman reigned ancient Egypt and closes of Memnon, in the evening transfer to the train station taking first class train back to Cairo.

描述探索奇迹古老的文明，如埃及，第三个不知道的世界游览行程当您在开罗，你可以充分享受两天访问卢克斯特，你将被转移到您的酒店在晚上9点转移到火车站到晚上10点火车到卢克索第一天上午8时30分拿起从火车站开始在卢克索和导游与集团看到卡纳克神庙，最伟大的榜样，崇拜的历史，致力于神阿蒙，他的妻子突变和和他们的儿子孔苏，然后将检查卢克索神庙和晚上在酒店在卢克索第2天上午7时开始导游与集团看到帝王谷，王后谷，庙Hatshpsute皇后唯一的女法老统治古埃及和关闭的Memnon ，晚上转移到火车站采取头等舱火车回开罗举行。

The first part - introduction, metasomatism background, The second part, after 80 consumption group consumption psychology and behavior, The third part, through the description of the second part after 80 consumer groups to reveal the influence of different aspects of advertising creative, The fourth part, through the front of modern advertisement should be further discussed how to innovate, seize after 80 consumer groups.

第一部分—引言，交代时代背景；第二部分，阐述80后消费群体的消费心理和行为特征；第三部分，通过第二部分的描述揭示80后消费群体对广告创意不同方面的影响；第四部分，通过前面的说明进一步论述现代广告应如何创新，抓住80后消费群体。

This nation's military power is only the third and fourth place in the world.

这个国家的军事实力，只不过是第三和第四在世界上。

So ask yourself whether you need that third helping, and whether an eighth mince pie is really a good idea.

所以问问你自己，是否需要点第三份餐，是否要吃下第八块肉馅饼。

One reason is that the model is an algebra method and it is based on the theory of minimal element. It can give more credible proof. Another reason is that the model tries to prove security of protocols, rather than check them. Thirdly, the model is simple and easy to use, and proof can be finished by manual. Moreover, graphic description makes its proof more comprehensible. Fourthly, there is much research work related to the model, which gives me a good springboard.

首先，该模型是一种代数方法，以极小元等理论为基础，可以给出可信度较高的证明；其次，该模型不是验证协议，而是试图证明协议的安全性；第三，该模型简单、易用，可以手工的方式完成证明，而且图形表示使其证明更加直观；第四，关于该模型有许多相关的研究工作，这为进一步工作打下了良好的基础。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
