【正文】 模擬的某三維翼型表面的水滴容積分?jǐn)?shù)云圖，可以看到，撞擊區(qū)基本位于迎風(fēng)表面；在背風(fēng)區(qū)是不存在水滴撞擊的，因而也難以發(fā)生結(jié)冰。涂層表面的粗糙程度也是決定冰黏附強(qiáng)度的因素之一，表面具有合適的微/納米結(jié)構(gòu)和一定的粗糙程度(或表面紋理)，不僅可以提高表面的疏水性能，延遲結(jié)冰時(shí)間，而且可以截留停留在涂層表面水分子下的部分空氣，造成冰體與基體界面的應(yīng)力集中，在一定的外力作用下(如震動(dòng)、傾斜、剪切力等)，使冰更易從涂層表面脫落。加熱情況下,由于涂層表面的超疏水特性,超疏水涂層表面可以有效抑制溢流冰層的形成,減少結(jié)冰面積率,可以節(jié)省的電能高達(dá)34%。but today they are a threat to everyone who use the internet, we have already acquire some knowledge last will present another reason that may cause the is the loophole of the will say a incident about network security that happened is a famous software that almost everyone here is using now, that is are reports ing from the users that AliPay realname user open the realname authentication inadvertently and then find that there are five more unknown account that is not unknown account name of loan is also in his real name is to say, he should repay other people’s officialresponse to this is that firstAlipay realname authentication binding process does not need to confirm the account that has already been realname authentication , also do not need to login in the account that is already realname, as long as the applicant submit identity information and certified account ,if agreement is certified,they will default , the binding function of the Alipay realname account requires the user to log in his AliPay to see real name account binding, instead of a real time notice like sending a short message, Email ,if you want to delete child account, you have to appeal, and upload id is very alipayofficial say that the leak of the personal privacy information that lead to pass the certification finally ,but do not be worried,they say thatIf the account has been stolen money ,he will receive the highest 1 million yuan we hope the pany can improve the software to do more better job for there is a question in the end, can we trust in the information technology or we should abandon answer is absolutely we should trust of all , information technology(IT)is playing an important role in our life and people today rely on IT more than ever can see people play their phone everywhere and everytime, information technology has Penetrate into our life, and exchange our life, obviously ,almost everybody here have more than one application as make our life more rich and colorful, more fast and let us use the least amount of time to do the most the progress of the society on the one ,The developmnt of information technology is a manifestation of social progress to some transformation has tremendous potential for enriching and enhancing our daily lives, while sparking a new era of growth for the global we meet some question on the way , we should think some good solutions to solve it ,not in this way ,can our society develop better and development of IT create vast new opportunities to enrich our lives and rewire our economy, but it also offer a tempting target for criminals and , to meet these challenges, we must change the way we create a truly trustworthy puting is a longterm challenge , but it is essential that we meet it.第五篇：PPT講稿文普二班蘭曉茹學(xué)號(hào)：052012年國(guó)內(nèi)外大事講稿一、首屆冬季青年奧林匹克運(yùn)動(dòng)會(huì)1月13日至22日，首屆冬季青年奧林匹克運(yùn)動(dòng)會(huì)將在奧地利的因斯布魯克舉行。冠軍被效力于梅賽德斯車(chē)隊(duì)的德國(guó)車(chē)手尼克羅斯伯格獲得。之后，婦女、兒童、工商業(yè)、科技行業(yè)等九大群體的代表也相繼在開(kāi)幕式上發(fā)言，表達(dá)了不同人群對(duì)于促進(jìn)可持續(xù)發(fā)展的看法和意見(jiàn)。北京時(shí)間8月13日，2012年倫敦奧運(yùn)會(huì)閉幕式在倫敦碗拉開(kāi)帷幕。在十八會(huì)議上，選舉新一屆的中共中央領(lǐng)
