Specifying the right reference and applying it correctly isa more difficult task than one might first surmise, consideringthat references are only 2- or 3-terminal devices.Although the word “accuracy” is most often spoken inreference to references, it is dangerous to use this wordtoo freely because it can mean different things to differentpeople. Even more perplexing is the fact that a referenceclassified as a dog in one application is a panacea inanother. This application note will familiarize the readerwith the various aspects of reference “accuracy” andpresent some tips on extracting maximum performancefrom any reference.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A new low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.

BeanShell是一個小型的，免費的，可嵌入式的，具有面向對象腳本語言特性的Java代碼解釋器。它是用Java語言寫的。它能執行標準的Java語句和表達式，還自帶簡單的腳本命令和語法。它把編程對象當成一個簡單的方法，這很像Perl和JavaScript.
你可以在寫Java測試或調試時使用BeanShell，也可以用它作為你的應用程序的腳本引摯。簡而言之，BeanShell可以動態的解釋JAVA語言。也就是說BeanShell在許多方面對于Java的用處就像Tcl/Tk對于C的用處一樣：BeanShell是可嵌入式的---你可以在運行時從你的應用程序調用BeanShell去動態的執行Java代碼或是為你的應用程序提供腳本擴展。相反，你也可以從BeanShell調用你的應用程序及其對象，它可以讓JAVA對象和API動態運行。正因為BeanShell是用JAVA寫的，所以它可以和你的應用程序運行在同一個JVM空間內，你也可以自由的傳遞實時對象的參照(references)到腳本代碼中并且作為結果返回。

詞法分析器制作與應用
設計思想
(1)程序主體結構部分：
說明部分
％％
規則部分
％％
輔助程序部分
（2）主體結構的說明
在這里說明部分告訴我們使用的LETTER,DIGIT, IDENT(標識符,通常定義為字母開頭的字母數字串)和STR(字符串常量,通常定義為雙引號括起來的一串字符)是什么意思.這部分也可以包含一些初始化代碼.例如用#include來使用標準的頭文件和前向說明(forward ，references).這些代碼應該再標記"％{"和"％}"之間 規則部分> 可以包括任何你想用來分析的代碼 我們這里包括了忽略所有注釋中字符的功能,傳送ID名稱和字符串常量內容到主調函數和main函數的功能.
（3）實現原理
程序中先判斷這個句語句中每個單元為關鍵字、常數、運算符、界符，對與不同的單詞符號給出不同編碼形式的編碼，用以區分之。
PL/0語言的EBNF表示
<常量定義>：：=<標識符>=<無符號整數>
<標識符>：：=<字母>={<字母>|<數字>}
<加法運算符>::=+|-
<乘法運算符>::=*|/
<關系運算符>::==|#|<|<=|>|>=
<字母>::=a|b|…|X|Y|Z
<數字>::=0|1|2|…|8|9

KEPware Automation DLL installation instructions:
To use the KEPware Automation DLL in your Visual Basic project:
1) In the VB IDE, Select "Project/references".
2) If you have been using another vender s automation dll, uncheck it.
For example, uncheck "OPC Automation 2.0" for the OPC Foundation s
automation dll.
3) Check "KEPware OPC Automation 2.0".
4) Recompile your VB project. If you have been using the OPC Fondation s
automation dll, you should not need to make any changes to the VB
source code.
