【正文】 系統(tǒng)。在這些設(shè)備中，氨制冷系統(tǒng)是最大的能源消耗部分。結(jié)果表明，安裝兩次基線聚光能力，內(nèi)部收益率超過20 ％。以說明氣候的影響，這些模擬是兩個不同的ASHRAE氣候區(qū)，邁阿密，佛羅里達(dá)州和執(zhí)行明尼阿波利斯，明尼蘇達(dá)州，這是炎熱和寒冷的氣候分別。本文研究系統(tǒng)能源利用中聚光能力和冷凝器的控制之間的關(guān)系。在參考該表時，要注意，由JSp頁面生成的servlet使用_jspService方法（GET和pOST請求都調(diào)用該函數(shù)），不是doGet或dopost方法。Servlet在編譯后，載入到服務(wù)器的內(nèi)容中，初始化并執(zhí)行。l瀏覽器根本不“支持”JSp它們看到的只是JSp頁面的輸出。因此：l如果要將使用Swing組件的applet放到網(wǎng)頁中，重要的是瀏覽器的Java版本，和服務(wù)器的Java版本無關(guān)。我如何將Swing組件用到JSp頁面中呢？l我如何將圖像放到JSp頁面中？我不知道讀取圖像文件應(yīng)該使用哪些Java I/O命令。此外，業(yè)界對JSp和Servlet技術(shù)的巨大支持使得這兩項(xiàng)技術(shù)都有了巨大的進(jìn)步，從而減輕了對JSp的許多批評。例如，Servlet和JSp規(guī)范為Web應(yīng)用定義了一個標(biāo)準(zhǔn)的目錄結(jié)構(gòu)，并提供用于部署Web應(yīng)用的標(biāo)準(zhǔn)文件（.war文件）。使用擴(kuò)充JSp和Servlet技術(shù)的第三方工具，如Apache Structs，是一種很好的思路，只要該工具帶來的好處能夠補(bǔ)償工具帶來的額外復(fù)雜性。這是一件好事，JSp的優(yōu)勢之一是該規(guī)范由許多不同公司組成的社團(tuán)控制。JavaScript也可以用在服務(wù)器端，最因人注意的是SUN ONE（以前的iplanet）、IIS和BroadVision服務(wù)器。這是一項(xiàng)有用的功能，一般與JSp的功能（只在服務(wù)器端運(yùn)行）并不發(fā)生重疊。JSp擅長生成由大量組織有序的結(jié)構(gòu)化HTML或其他字符數(shù)據(jù)組成的頁面。不了解Servlet就無法知道JSp如何工作。實(shí)際上，JSp文檔在后臺被自動轉(zhuǎn)換成Servlet。與pHp相比pHp（“pHp：Hypertext preprocessor”的遞歸字母縮寫詞）是免費(fèi)的、開放源代碼的、HTML嵌入其中的腳本語言，與ASp和JSp都有某種程度的類似。使用JSp,動態(tài)部分是用Java編寫的,而非VBScript過其他ASp專有的語言,因此JSp更為強(qiáng)勁,更適合于要求組件重用的復(fù)雜應(yīng)用。其次，對于某些應(yīng)用，底層語言的選擇至關(guān)重要。JSp的優(yōu)勢體現(xiàn)在兩個方面。因此,問題變成:為什么使用JSp,而不使用其他技術(shù)呢?我們的第一反應(yīng)是我們不是在爭論所有的人應(yīng)該做什么。Java社團(tuán)沒有發(fā)明這一思想將頁面設(shè)計(jì)成由靜態(tài)HTML和用特殊標(biāo)簽標(biāo)記的動態(tài)代碼混合組成.。二、JSp相對于競爭技術(shù)的優(yōu)勢許多年前，Marty受到邀請,參加一個有關(guān)軟件技術(shù)的小型(20個人) GoslingJava編程語言的發(fā)明者。在此，這個討論并不是讓您停止使用servlets，只使用JSp。Java程序員可以致力于動態(tài)代碼。JSp中可以使用常規(guī)的HTML：沒有額外的反斜杠，沒有額外的雙引號，也沒有暗含的Java語法。然而，這種底層的等同性并不意味著servler和JSp頁面對于所有的情況都等同適用。those tags are processed on the server and are not part of the output that is sent to the Translation Time with Request TimeA JSp page is converted into a servlet is piled, loaded into the server39。s Java version—the server39。t understand how JSp works without understanding consists of static HTML, specialpurpose JSp tags, and Java kind of Java code? Servlet code!You can39。s C language is very well designed and is similar to Java, fewer programmers are familiar with either the core C syntax or the many auxiliary addition, many developers still use the original version of this version, JSp has a clear advantage for the dynamic JSp, the dynamic part is written in Java, not VBScript or another ASpspecific language, so JSp is more powerful and better suited to plex applications that require reusable could make the same argument when paring JSp to the previous version of ColdFusion。附錄 二外文原文Asynchronous motor has a simple structure, reliable operation, low price, convenient maintenance and a series of advantages, therefore, asynchronous motor is widely used in electric drive with the development of power electronic technology and AC drive technology bees more mature, greatly improve the speed performance makes the asynchronous present, electric drive asynchronous motor has been widely used in various industrial electrical mechanical properties of threephase asynchronous motor starting, the main motor starting, braking, speed control mechanical properties of 1 threephase asynchronous motor Mechanical characteristics of threephase asynchronous motor is refers to the relationship between the speed of the motor electromagnetic torque of N and to the speed of N and slip S have a certain relationship, so the mechanical properties are also monly used Tem = f(s) torque expression of threephase asynchronous motor has three forms, namely physical expression, parameters and practical expressions reflect the physical nature of electromagnetic torque of asynchronous motor, the electromagnetic torque is generated by the main flux and rotor active current expression reflects the relationship between parameters of electromagnetic torque and power supply parameters and motor, the expression can be used to influence easily analyze the influence of parameter variation on the electromagnetic torque and all kinds of human expressions in a simple, easy to remember, is often used in engineering calculation in the form maximum torque of motor and torque are two important indexes reflecting the overload capacity of the motor and starting performance, maximum torque and start torque motor overload capacity is bigger, stronger, better starting mechanical characteristic of threephase asynchronous motor is a nonlinear curve, under normal circumstances, with the maximal torque(or critical slip)as a cutoff point, the linear segment for the stable operation region, while the nonlinear section is not stable operating characteristic is linear segment inherent mechanical properties, the nominal operating point speed slightly lower than the synchronous parameters available expressions manmade mechanical characteristic curve analysis, analysis the key to grasp the maximum torque, starting torque variation of critical slip and the three with the parameters threephase asynchronous motor starting Threephase asynchronous motor with small capacity can be used to directly start, cage motor with large capacity can adopt stepdown start into stator resistance or reactance stepdown start, YD stepdown start and autotransformer stator resistance or motor stepdown start, starting current voltage relations with a reduced, and the starting torque with the square of the voltage is reduced, it is suitable for the starting applicable to motor start to normal operation for the triangle connection YD buck, the starting current and starting torque is reduced to direct startup 1/3, which is also suitable for the starting start, starting current and starting torque is reduced to direct startup l/k2(k is the self coupling transformer), suitable for large load wound rotor asynchronous motor with rotor series resistance or frequency sensitive rheostat starting, the starting torque, small starting current, suitable for heavy load starting, large asynchronous soft starter is a novel control device for motor motor soft start, soft stop, light load energy saving and various protecting functions in one, called Soft main structure is connected in series between the power supply and the controlled motor threephase inverse parallel thyristor and its electronic control the series of sof
