station。會議旨在為科研工作者和工程技術(shù)人員提供一個報道先進研究成果、交流學(xué)科前沿動態(tài)的平臺。會上與國際知名學(xué)者交流，感受了國內(nèi)、國際權(quán)威學(xué)者的敏銳思維、學(xué)習(xí)專家解決難題的靈活方式、感覺受益匪淺。具體內(nèi)容是：隨著軟件產(chǎn)業(yè)的快速發(fā)展，以反跟蹤技術(shù)為核心的軟件安全已經(jīng)成為一個重要的課題。結(jié)構(gòu)化異常處理，是操作系統(tǒng)提供的用于解決系統(tǒng)軟硬件異常的一種機制，在程序設(shè)計中的合理使用可以提高軟件的穩(wěn)定性、容錯性。應(yīng)用程序正常執(zhí)行中出現(xiàn)異常時, 操作系統(tǒng)將收集異常發(fā)生的原因、類型、位置等信息，填寫相關(guān)的數(shù)據(jù)結(jié)構(gòu),并從用戶程序轉(zhuǎn)到系統(tǒng)級執(zhí)行,將控制權(quán)交給系統(tǒng)的異常調(diào)度函數(shù)。用戶可定義的異常處理例程分為兩種；一種是線程相關(guān)的，一種是進程相關(guān)的:線程相關(guān)的異常處理例程,監(jiān)視某線程中某段代碼是否發(fā)生異常，由于線程是程序執(zhí)行的最小單位，所以把異常解決于線程的內(nèi)部，可以避免該異常對其它線程的干擾，保證程序的穩(wěn)定運行。異常處理流程是指運行在win32系統(tǒng)中的程序通常包含多個線程，而每個線程都會安裝各自的異常處理例程；除此之外，程序中可能存在一個全局性的異常處理例程；再者，如果進程被調(diào)試的話，調(diào)試進程也相當于一個異常處理例程。如果應(yīng)該發(fā)送，并且目標程序正在被調(diào)試．則系統(tǒng)掛起程序；如果程序沒有被調(diào)試或者調(diào)試器未能處理異常，系統(tǒng)繼續(xù)查找是否安裝了線程相關(guān)的異常處理例程。每個線程相關(guān)的異常處理例程可以處理或者不處理這個異常，如果它不處理并且安裝了多個線程相關(guān)的異常處理例程可交由鏈起來的其他例程處理；如果這些seh處理例程均不處理異常，且程序處于被調(diào)試狀態(tài)，操作系統(tǒng)會再次通知調(diào)試器；如果程序未處于被調(diào)試狀態(tài)或者調(diào)試器沒有能夠處理，并且程序調(diào)用setunhandledexceptionfilter函數(shù)安裝了進程相關(guān)的異常處理例程的話，系統(tǒng)轉(zhuǎn)向?qū)λ恼{(diào)用；如果沒有安裝進程相關(guān)的異常處理例程或者它沒有處理這個異常，系統(tǒng)會調(diào)用默認的異常處理例程，通常顯示一個對話框，用戶可以選擇“關(guān)閉”或者可以將程序附加到調(diào)試器的“調(diào)試”按鈕。通過對系統(tǒng)異常處理流程分析可知，當應(yīng)用程序執(zhí)行過程中發(fā)生異常時，系統(tǒng)可在三個層次上完成異常處理：調(diào)試器、進程、線程。下面深入分析seh的工作原理。下面圍繞異常處理例程深入分析系統(tǒng)級異常處理機制。如果找到的處理例程處理了異常并繼續(xù)執(zhí)行，則對rtldispatchexception 的調(diào)用不再返回。若是后者，異常不再繼續(xù)，進程必須終止。seh在軟件反跟蹤中的主要應(yīng)用方式是調(diào)試工具的檢測、硬件斷點的去除、改變程序執(zhí)行順序等，但這些反跟蹤技術(shù)相對比較成熟，很容易被破解者發(fā)現(xiàn)并成功破解。在程序的正常執(zhí)行序列中設(shè)置功能請求標志位，之后觸發(fā)單步異常，進入異常處理例程后根據(jù)標志位完成所抽取的相應(yīng)的功能，繼續(xù)程序的運行。這是因為異常發(fā)生后，調(diào)試器接管了異常，而不會去調(diào)用作者安裝的實現(xiàn)具體功能的異常處理例程，從而達到反跟蹤的目的。插入單步異常指令，此處是關(guān)鍵的地方，因為程序的反調(diào)試功能通過它來實現(xiàn)。清除異常處理例程，程序執(zhí)行完功能代碼后，要把開始時安裝的異常處理例程去除，否則容易引起系統(tǒng)錯誤。這次參加icacte國際會議，通過和與會學(xué)者的交流、探討，我覺得自己的收獲主要在以下方面：對自己專業(yè)的新動態(tài)有了一定的把握，對本行業(yè)內(nèi)的其他專業(yè)方向有了一定的了解；發(fā)現(xiàn)了自己在學(xué)術(shù)上存在的問題，這有助于以后的改進和提高；結(jié)識了一些日本、韓國、臺灣等地高校和公司的教授、研發(fā)人員和學(xué)生，為以后更廣泛的交流打下了基礎(chǔ)；發(fā)現(xiàn)了自己英語水平的不足，這將促使我更加努力地掌握英語，尤其是提高口語水平。非常感謝我校研究生院給予的此項支持，鼓勵研究生參加國際會議是符合建設(shè)國際型大學(xué)的潮流之舉。2014年12月26~ 26 ~第二篇：國際學(xué)術(shù)會議發(fā)言稿Thank you, , for your gracious am honored to have the chance to address you on this special topic of my paper is “Transaction Cost and Farmers’ Choice of Agricultural Products Selling”.The outline of my talk as first part I want to introduce the background of this second part suggests a simple household choice third part covers the data used in this then, we introduce the empirical , a simple conclusion is Well, let’s move on the first part of this motivation of this work like economics posits that agents making decisions on different types of transactions do so in a costly example , farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these want to use a picture to illustrate example, given some market channels, farmers’ choices can be regarded as equilibrium between the surplus and the additional costs that related to in developing countries, highvalue crop producers fully participate in the market and the transaction cost has been the hard constraint to , Farmers’ market choices can be taken as a choice dilemma of transaction cost and production , the scientific question of this research is how transaction cost affects planters’ Let’s move to the theoretical model of our a household model in one stage 1 , famer η needs to allocate the input process can qbe set into a function like this Qh = Q(p , w , z h), Qη means the output farmers decide qto implies the Output price W implies Input Price : h is fixed produce what and produce how many are decided, next question to be considered is how much products to be transacted in we use three cc()Cη means how functions to describe this first equation, c h =p , z hmuch agricultural products used by famers implies the price the cagricultural product,z hsuggests the fluctuation of second equation q h = Q h ch, qη means the amount of agricultural products transacted in third equationi = q himplies the amount exchanged in nth Stage 3, farmers will decide to sell the products to j’s market price isbdecided by an exogenesis price and farmers’ negotiating =p*j+B(qi,zi)Besides this, we use a matrix to show the net profit of Chanel jX ike ik, b +213。 k=1Based on the choice model, another important concept is famers’ channel , we set five rank by the market , we set a group discrete number to express : dependent variable Y=5,means farmer choose=1, farmers sell products to consumers and estimation proceduresHere, we illustrate the data distribution with this to the Agricultural regionalization from Department of Agriculture, The apple specialization areas in China contain two parts: Bo Sea area and Loess Sea Area in red color, contains Hebei, Shandong and Liaoning 3 Loess Plateau in green color, contains Shanxi, Henan, Shaanxi and Gansu 4 , we use PPS method to get the first stage sampling unit 14 counties in 7 use random sample method to get village and are our sample Results第三篇：國際學(xué)術(shù)會議論文Description of the Antibiotics ShaoZengHua from Cl
