Description: 将文件拷贝到UCH安装目录(不会覆盖任何UCH文件).
其中config.shop.inc.php文件需要有写权限(linux).
运行shop_install.php
打开shop.php文件。将
$_SC['GoogleAPI']='ABQIAAAAIl6BzjiDCz90JrLDCFco6xRsRMjB2wv1Y7bZb-CPY4a_zZ8tAhQljtAew1TctFXLCYxRjkaGoD8jzA';替换成您的Google KYE。如您在本地调试，可以直接用以上KEY。如您还没有google KEY 请到
http://code.google.com/intl/zh-CN/apis/maps/signup.html 免费申请！
地图显示您想要的地方的方法：
首先打开Google地图，在上面寻找一个地址，然后上下左右移动地图，让这个地址正好处于地图的正中心位置，当您想寻找坐标位置已经处于地图的中心位置的时候，拷贝并粘贴以下代码到你的浏览器地址栏：
javascript:void(prompt('',gApplication.getMap().getCenter()));
然后回车一下。这时，你将得到一个弹出式的坐标，这个坐标就是你需要找的经度和纬度。
1 在admincp.php:
第一处：
$acs = array(
array('index','config','privacy', 'spam', 'network', 'usergroup', 'credit', 'profilefield', 'profield', 'ad', 'sitefeed', 'userapp', 'app'),
array('tag', 'mtag', 'space', 'name', 'report'),
array('cache', 'task', 'censor', 'stat', 'block', 'cron'),
array('blog','album', 'pic', 'comment', 'thread', 'post', 'doing', 'feed', 'share')
);
修改成(最后一行array('base','pingdao','neirong','shop','reviews','shoptags')为增加的。同时记得在上一行'share')后加个逗号 )
$acs = array(
array('index','config', 'privacy', 'spam', 'network', 'usergroup', 'credit', 'profilefield', 'profield', 'ad', 'sitefeed', 'userapp', 'app'),
array('tag', 'mtag', 'space', 'name', 'report'),
array('cache', 'task', 'censor', 'stat', 'block', 'cron'),
array('blog', 'album', 'pic', 'comment', 'thread', 'post', 'doing', 'feed', 'share'),
array('base','pingdao','neirong','shop','reviews','shoptags')
);
第二处：
for($i=0; $i<5; $i++) {//由原来的3改成现在的5,其他不用修改
foreach ($acs[$i] as $value) {
if($isfounder || $megroup['manage'.$value]) {
$menus[$i][$value] = 1;
$_SGLOBAL['usergroup'][$_SGLOBAL['member']['groupid']]['manage'.$value] = 1;
}
}
}
第三处：
if(empty($_GET['ac']) || (!in_array($_GET['ac'], $acs[0]) && !in_array($_GET['ac'], $acs[1]) && !in_array($_GET['ac'], $acs[2]) && !in_array($_GET['ac'], $acs[3]) && !in_array($_GET['ac'], $acs[4]) && !in_array($_GET['ac'], $acs[5]))) {
//加上 && !in_array($_GET['ac'], $acs[4] && !in_array($_GET['ac'], $acs[5])，注意修改完后$acs[5]后面应有三个 ) 符号
3 admin/tp/header.htm:
<!--{eval
$_TPL['menunames'] = array(
'config' => '站点设置',
后加上：
'base' => '积分与审核',
'pingdao' => '频道设置',
'shoptags' => '标签管理',
'shop' => '商铺管理',
'neirong' => '点评内容',
'reviews' => '回应内容',
4 admin/tpl/side.htm开始处加入:
<!--{if $menus[3]}-->
<div class="block style1">
<h2>点评系统</h2>
<ul class="folder">
<!--{loop $acs[4] $value}-->
<!--{if $menus[4][$value]}-->
<!--{if $ac==$value}--><li class="active"><!--{else}--><li><!--{/if}--><a href="admincp.php?ac=$value">{$_TPL[menunames][$value]}</a></li>
<!--{/if}-->
<!--{/loop}-->
</ul>
</div>
<!--{/if}-->
5 在侧栏增加链接。
template/default/header.htm中找到
<li><img src="image/app/share.gif"><a href="space.php?do=share">分享</a></li>
加上
<li><img src="image/icon/shop.gif"><a href="shop.php">商家点评</a><em><a href="shop.php?ac=new">发布</a></em></li>
更新缓存。
如果安装后出现白屏现象，请重新检查所安装文件是否有语法错误。然后通过删除UCH安装目录下的data/tpl_cache/目录下的文件，此功能相当于更新缓存。
运行shopinstall.php
在header.htm相应的位置加上<li><img src="image/icon/shop.gif" alt="通讯录" /><a href="shop.php">通讯录</a></li>
admin/tpl/config.htm
找到<tr>
<th>未认证实名权限</th>
<td>
<table>
<tr>
<td width="120">允许加好友</td>
<td>
<input type="radio" name="config[name_allowfriend]" value="1"<!--{if $configs[name_allowfriend] == 1}--> checked<!--{/if}-->>是
<input type="radio" name="config[name_allowfriend]" value="0"<!--{if $configs[name_allowfriend] != '1'}--> checked<!--{/if}-->>否
</td></tr>
在其下面添加
<tr>
<td width="120">允许商铺点评</td>
<td>
<input type="radio" name="config[name_allowshop]" value="1"<!--{if $configs[name_allowshop] == 1}--> checked<!--{/if}-->>是

Description: This application report describes how to simultaneously create a sine wave, a ramp, and a dc
level with pulse-width modulated (PWM) signals from Timer_B on the MSP430 ultralow power
family of microcontrollers. PWM signals are often used to create analog signals in embedded
applications. This report shows how to create both ac signals and dc levels with PWM outputs.
The example in this report uses Timer_B on the MSP430F149, but Timer_A could also be used
in a similar manner.

Description: The ever-increasing reliance on electronic devices which utilize AC power highlights the problems associated with the unexpected loss of power from the electrical grid. In places where the electrical infrastructure is not well-developed, brown-outs can prove fatal when electronic medical instruments become unusable. Therefore, there is a need for inexpensive and reliable pure-sine wave inverters for use with medical devices in the underdeveloped world. This report documents the development of one component of an uninterruptible power supply, the DC-to-AC inverter. Through the use of analog signal processing techniques, a prototype which efficiently and accurately emulates the pure-sine wave power present on the power grid was created. The three-level PWM system within this report is created with the possibility of a feedback-regulated system to be implemented in the future.

Description: This report focuses on DC to AC power inverters, which aim to efficiently transform a DC power
source to a high voltage AC source, similar to power that would be available at an electrical wall outlet.
Inverters are used for many applications, as in situations where low voltage DC sources such as batteries,
solar panels or fuel cells must be converted so that devices can run off of AC power. One example of
such a situation would be converting electrical power from a car battery to run a laptop, TV or cell
phone.
