[size=x-large][b]1 denote [/b][/size]
英[diˈnəut]
1.为…的符号; 为…的名称,标志;预示;象征
In algebra, the sign X usually denotes an unknown quantity.
在代数里, 符号X常用来表示未知数。
2.指示; 指出,表示;意指
We often denote danger by red letters.
我们常常用红字表示危险。

definition : Value denote a definition defined in factory (xml
* file).

[b][size=x-large]2 tiles:insertTemplate[/size][/b]
Insert a template.
Insert a template with the possibility to pass parameters (called attributes). A template can be seen as
a procedure that can take parameters or attributes. <tiles:insertTemplate> allows to define these
attributes and pass them to the inserted jsp page, called template. Attributes are defined using nested
tag <tiles:putAttribute> or <tiles:putListAttribute>.
You must specify template attribute, for inserting a template
Example :

<tiles:insertTemplate template="/basic/myLayout.jsp" flush="true">
<tiles:putAttribute name="title" value="My first page" />
<tiles:putAttribute name="header" value="/common/header.jsp" />
<tiles:putAttribute name="footer" value="/common/footer.jsp" />
<tiles:putAttribute name="menu" value="/basic/menu.jsp" />
<tiles:putAttribute name="body" value="/basic/helloBody.jsp" />
</tiles:insertTemplate>
内容概要:本文档详细介绍了Analog Devices公司生产的AD8436真均方根-直流(RMS-to-DC)转换器的技术细节及其应用场景。AD8436由三个独立模块构成:轨到轨FET输入放大器、高动态范围均方根计算内核和精密轨到轨输出放大器。该器件不仅体积小巧、功耗低,而且具有广泛的输入电压范围和快速响应特性。文档涵盖了AD8436的工作原理、配置选项、外部组件选择(如电容)、增益调节、单电源供电、电流互感器配置、接地故障检测、三相电源监测等方面的内容。此外,还特别强调了PCB设计注意事项和误差源分析,旨在帮助工程师更好地理解和应用这款高性能的RMS-DC转换器。 适合人群:从事模拟电路设计的专业工程师和技术人员,尤其是那些需要精确测量交流电信号均方根值的应用开发者。 使用场景及目标:①用于工业自动化、医疗设备、电力监控等领域,实现对交流电压或电流的精准测量;②适用于手持式数字万用表及其他便携式仪器仪表,提供高效的单电源解决方案;③在电流互感器配置中,用于检测微小的电流变化,保障电气安全;④应用于三相电力系统监控,优化建立时间和转换精度。 其他说明:为了确保最佳性能,文档推荐使用高质量的电容器件,并给出了详细的PCB布局指导。同时提醒用户关注电介质吸收和泄漏电流等因素对测量准确性的影响。
Write a C++ program that defines a class DateV2 that (1) Contains all the members in the class DateV1; Programming for Engineers C++ (2) Has two constructors as follows: One takes three parameters, int y, int m, int n; The other is the default constructor that takes no parameter (3) Has additional public member functions as follows: string getWeekDay(); // return the week day, for example, Sunday if day is 0, etc bool Leap(); // return if the year is leap int differFrom(DateV2& oneDate); // return the difference in days between the calling object // and the oneDate object void printDate(); // print the year, the month in English, the day, and the week day Test class DateV2 in the main function as follows: (1) Declare and set the objects today and tomorrow as in Problem 2. (2) Declare and initialize (by a constructor) an object to represent your OWN birthday. (3) Use the member function printDate to print today, tomorrow, and your birthday. (4) Output the weekday of today, tomorrow, and your own birthday. (5) Output how many days has passed since your birth (the difference between your birthday and today). Hint: i) We can use another string array to store the English name for week days (Sunday, Monday, through Saturday) ii) We know that it is Monday on Year 1, Month 1, and Day 1 iii) A good idea is to first design a function to compute the number of days that has passed since Year 1, Month 1, and Day 1, and then to use this function to compute the week day for a give date and to compute the difference between two dates. You can store the number of days for each of the 12 months in an integer array, which helps in counting the days.
