postform

The server used many open source softwares and based on the open source mail software postfix , manage mysql to administer the user in the system , and provided a web interface , also include the smtp , pop3 and imap function , support large scale user requests and the sasl authentication mechanismcan . etc 該系統利用了多個開放源碼軟件,以開放源碼郵件軟件postfix為基礎,采用了mysql來管理用戶,可支持大規模用戶的請求,同時提供了一個web的郵件管理界面。該郵件服務器包含了smtp 、 pop3和imap的功能、支持sasl驗證機制等安全措施。

The paper discussed the following four points : the security of java , the implemention of mvc pattern and the principle and implemention of the send and incept of e - mail based on java ; the principles and implemention of smtp , pop3 and imap , and the characteristic of the e - mail server sendmail , qmail and postfix ; the principles and implemention of symmetrical encryption and unsymmetrical encryption technology , and the advantages and disadvantages of them ; the characteristic of rubbish e - mail , and the principles and implemention of anti - rubbish e - mail technology 本文研究的主要內容包括: java技術安全性, java對mvc模式的實現,以及java技術解決電子郵件發送和接收問題的原理和實現方法;電子郵件相關協議smtp , pop3和imap的原理和實現方法,以及電子郵件服務器sendmail 、 qmail和postfix的特點;對稱加密與非對稱加密技術的原理和實現方法,以及兩者的優點和缺點;典型垃圾郵件的特征,以及反垃圾郵件技術的原理和實現方法。

According to the characteristic of cfrf , we develop the calculation method of postfix form that can reduce calling cfl sentence parsing and redundant evaluation to improve the efficiency 根據cfrf的特點,提出了后綴形式的計算方法,減少在函數計算中存在的動態語法分析,避免了不必要的求值計算,使效率得到提高。

To convert an expression in an infix expression to its equivalent in postfix notation , we must know the precedence and associativity of operators 要把表達式從中綴表達式的形式轉換成用后綴表示法表示的等價表達式,必須了解操作符的優先級和結合性。

Fortunately , perl makes it easy to write good code with simplified loop constructs , postfix if unless branching , and a whole lot more 幸運的是,有了perl ,我們可以輕松地用簡化的循環構造、后綴if / unless分支語句和更多的方式編寫優秀的代碼。

After this with a real popular mail server , postfix , analyze and describe how to accomplish mail filtering in it 然后,結合一個流行的郵件服務器? ? postfix深入分析了郵件過濾的原理及機制,以及在postfix中實現郵件過濾的具體方法。

By default , a column can contain a null value , but if you don t want that , you can append the “ not null “ postfix to the field definition 默認情況下,列可以包含null值,但是,如果不想這樣,可以在字段定義中附加“ not null ”后綴。

Infix notation is a common way of writing expressions , while prefix and postfix notations are primarily used in computer science 中綴表示法是書寫表達式的常見方式,而前綴和后綴表示法主要用于計算機科學領域。

In postfix notation , the need for parentheses is eliminated and the priority of the operators is no longer relevant 在后綴表達式中,不需要括號,而且操作符的優先級也不再起作用了。

It does not convert infix expressions to postfix notation ; rather , it evaluates the infix expression directly 不是把中綴表達式轉換為后綴表示法;恰恰相反,它對中綴表達式直接求值。

If you could not pop two operators , the syntax of the postfix expression was not correct 如果您不能夠彈出兩個操作數,后綴表達式的語法就不正確。

Write the following in normal non - postfix notation , and simplify them if you can 以通常(不帶后綴)的表示法編寫以下代碼,如果可以,則簡化它們:

Evaluating a postfix expression is simpler than directly evaluating an infix expression 對后綴表達式求值比直接對中綴表達式求值簡單。

2 . postfix operators have the highest order of precedence in expression evaluation 2 .后綴運算符在表達式計算中具有最高的優先級。

If the postfix expression was correctly formed , the stack should be empty 若后綴表達式格式正確,那么堆棧應該為空。

Yet sometimes i think that his name has a postfix of arsenal 至今有時候我仍然認為他的名字是阿森納的一個后綴?

Postfix notation is also known as 后綴表示法也稱

Evaluating the postfix expression 對后綴表達式求值

At the end of the postfix expression , pop a result from the stack 到后綴表達式末尾,從堆棧中彈出結果。
