The article points out the importance and necessity of the information - security from its actuality in our country. the resources in the information system, for instance, hardware, software, data, document, operator, meterial and so on, are evaluated and gived safety grade firstly. and then, it analyses the menace including the nonauthorized access, the information leak, the refused sevice, the internal objection which the system will take. the following are the corresponding control police : confirm the users " rights and duties, including the mode of using account, the limit of accessing resource, the application of password, the building of backup ; confirm the administrators " right and duties, including physical safety, system configuration, account configuration and usufruct, password management, audit and control, backup and individual intimity ; run - of - mill measure of security defence, including access control, symbol and identification, integrality control, password technique, firewall system, audit and resumption, safety of operating system, safety of database system, defence of computers " virus and resisting - deny protocol. in the end, the article offers the strategies of disposing the safety - accident and analyse after ithow. to report it, how to solve it in phase, and how to avoid it happening again. in a word, the article presents a holistic resolvent about keeping away the information system ' s security, and supplies a essential frame for its configuration, management and application
然後，對系統可能受到的威脅，包括非授權訪問、信息泄漏、拒絕服務和內部缺陷等進行分析，並提出了相應的控制策略：確定用戶的權力和責任，包括帳戶使用方式、資源訪問權限、口令應用以及建立備份等；確定系統管理員的權力和責任，包括物理安全、系統配置、帳戶設置及使用權限、口令管理、審計和監控、備份以及個人隱私等方面；一般性的安全防護措施：存取控制、標識和認證、完整性控制、密碼技術、防火墻系統、審計和恢復、操作系統安全、數據庫系統安全、計算機病毒防護和抗抵賴協議等。最後，對事故處理和事後分析提供策略，如何報告安全事故，如何協調解決安全事故，如何避免安全事故再次發生。總之，本文對信息系統安全防範工作給出一個整體的解決方案，為其在配置、管理和應用方面提供了基本的框架。 -

In the first part of this paper, we got some sufficient and necessary conditions about surjective toeplitz operators, through investigating symbol of toeplitz operator via j. bourgain fractorization theorem
本文第一部分應用j . bourgain分解定理對toeplitz運算元的符號的考察，得到了一些toeplitz運算元滿射的充分必要條件。 -
We detailed toeplitz operator with unomodular symbol, and generated the theorem proved by michael sand in [ 2 ] from h to h + c ( t ). in the second part of this paper, the author discussed simply when multipliction of two toeplitz operators with symbol in h + c ( t ) or in l. we got two conclusions by analyzing symbol of toeplitz operators. the last, we investigated whether multiplication of two toeplitz operators, which range included all non - cyclic vectors of backward shift, is surjective, and partly answered the question about surjective toeplitz algebra posed by michael sand in [ 2 ]
對于單個的toeplitz運算元，考慮其符號的內外分解，得到了它的滿射只與其幺模部分有關的結論，詳細地討論了符號為幺摸函數的toeplitz運算元的各種情況，在討論符號在h ~的特殊情形時，推廣michaelsand [ 2 ]中的定理2到h ~ + c （ t ） ，第二部分簡單地討論了符號在h ~ + c （ t ）以及l ~中的兩個toeplitz運算元的乘積的滿射情況，先對toeplitz運算元的符號進行分析得到兩個結論，最後考察了toeplitz運算元的乘積的值域包含后移運算元的所有非循環向量的滿射情況，部分地回答了michaelsand在[ 2 ]中提出的toeplitz代數滿射問題。 -

If the character is an operator, pop operators until you reach an opening parenthesis, an operator of lower precedence, or a right associative symbol of equal precedence
如果字元是個操作符，彈出（ pop ）操作符，直至遇見開括號（ opening parenthesis ） 、優先級較低的操作符或者同一優先級的右結合符號。
