二、kepserver 怎样处理数据？

你的问题不是很清楚，你连接数据库具体想干什么？

我做过这种程序：把别的应用程序保存在数据库中的内容读出来后，更新Kepware里相应的变量，DCS再读写这个变量即可。

三、检测总磷的数据怎样计算？

污水总磷检测时，应充分的了解待测污水的总磷含量的大体范围，便于确定是否需要对待测水样进行稀释测量，以保证测量数据的精准。

1、如果客户水样总磷不超过0.75mg/L,可以直接取8毫升，直接按照说明书的操作步骤测定例如：客户原水位5000mg/L，处理后不超过0.75mg/L，可以直接操作（前提是要水样相对澄清，无悬浮物、泥土、渣滓等杂质，如果有这些可以静置一会，取中间悬清液）。

2、如果客户水样总磷超过0.75mg/L，需要先稀释后，再按步骤操作实验。例如：客户原水总磷浓度比较高，为2mg/L，需要先稀释4倍，取25毫升定容在100毫升的容量瓶中。然后测定稀释后的污水样，出来的结果乘稀释的倍数4。就是原水总磷浓度。

3、如果客户水样中总磷超过0.75mg/L，酸性条件下，砷、铬、硫干扰试测定，这些干扰若多的话，首先要稀释到干扰浓度一下，在进行操作实验。例如：客户水样硫离子含量比较高，干扰测定，加入过硫酸钾后，溶液消解完，或者未消解后就发浑浊，先期要稀释一下，找几个稀释倍数点，测定结果中不会产生浑浊的话，再测定。总磷测量中稀释的常用手法1、稀释2倍，取100毫升容量瓶，量取100毫升蒸馏水，倒入500毫升烧杯中，使用同一个容量瓶，污水样先清洗2遍（因为挂壁的蒸馏水会稀释了水样，保证内壁是同一水样）量取100毫升，倒入同一个500毫升烧杯中，混匀。这样就是稀释了2倍。2、稀释4倍，使用25毫升的胖度吸管，量取25毫升污水样，定容在100毫升的容量瓶中，加蒸馏水到标线，混匀。3、稀释5倍，使用20毫升的胖度吸管，量取20毫升污水样，定容在100毫升的容量瓶中，加蒸馏水到标线，混匀。

4、稀释10倍，使用10毫升的胖度吸管，量取10毫升污水样，定容在100毫升的容量瓶中，加蒸馏水到标线，混匀。

四、表格数据重叠怎样处理？

1、电脑打开重叠的Excel表格。

2、打开Excel表格后，点击左上角的倒三角图标全选表格。

3、点击倒三角图标全选表格后，鼠标左键双击重叠单元格的数字线。

4、鼠标左键双击重叠单元格的数字线后，所有重叠的单元格就都显示出来了。

五、matlab怎样处理excel数据？

　　下面我就通过实例介绍一下MATLAB如何导入excel数据。

　　读取sheet1中的所有数据

　　我们以03版excel为例，假设excel中数据为

　　默认这些文本以及数字都放在sheet1中，我们将此excel选入当前工作目录（必要步骤），然后再MATLAB主窗口中输入下面命令：[NUM,TXT,RAW]=xlsread('example')，其中example是你的excel名，这里我所有的数据都在example.xls中。输入以上命令，回车

　　NUM返回的是excel中的数据，TXT输出的是文本内容，RAW输出的是未处理数据，这里因为文本占用的矩阵一共是8行6列，所以就输出了如上内容。一般情况下，我们读取的都是excel中的数据，所以可以直接用[NUM]=xlsread('example')，只输出数据矩阵便可。

　　读取指定sheet中的数据

　　假如我们想读取第二个sheet中的数据，这里请注意：matlab读取excel中的数据是按照sheet在excel中的排放顺序来的，sheet3现在排在第二位，我们输入命令[NUM]=xlsread('example'，2),回车

　　结果如下：

　　读取指定单元格中的数据

　　以sheet2中的数据为例

　　假设我们读取A3-D7之间的数据，那么我们输入命令[NUM]=xlsread('example',2,'A3:D7'),回车，结果如下：

六、污水处理总氮超标怎样处理？

看你现场有没有生化设施，如果有，尽量在前段对生化过程调节妥当，好氧段和厌氧段都没有问题的情况仍然超标的话，只能用HDN脱氮设备在末端提标；如果没有生化设施，比较麻烦，看你的废水水质能不能用HDN脱氮设备处理，这个要经历菌种训化和前期调试等环节，具体情况要具体对待。

七、亲戚总抢我家生意，怎样处理？

亲戚总是抢你家的生意，我认为应该可以这样处理。

一是，亲戚既然抢你的生意，你就不要再拿他们当作你的亲戚来对待，权当当做生意的对手，该出手时就出手，不必客气。

二是，亲戚总是抢你家的生意，说明你家的生意好，赢得了客户的信任，那你就做好自己的品牌，让他无法来抢。

三是，你可以研究对策，比如在价格上，服务上等各方面多做文章，扬长补短，去打压它，压缩他的利润空间。

八、excel怎样处理各个区块数据？

在Sheet2的B2单元格输入以下数组公式，按Ctrl+Shift+Enter组合键结束，然后向下填充公式 =INDEX(Sheet1!B:B,SMALL(IF(Sheet1!A$2:A$50=A2,ROW($2:$50),4^8),COUNTIF(A$2:A2,A2)))

九、EXCEL导不出数据怎样处理？

比如数据在A列，数字是文本类型的。你在B1输入公式=--A1然后下拉填充。然后选中B列复制，再直接在B列上点右键--选择性粘贴--粘贴为值，这样就覆盖掉了原来的，只保留了值，去除了公式。B列中的数据已经变为数值类型了。然后把原来的A列删除就可以了。

十、edta测水的总硬度实验数据处理？

1、钙、镁是水中最常见离子,蒸馏水（去离子水）要严格处理.

2、EDTA标定最好与滴定总硬度的条件（缓冲溶液、pH、指示剂）保持一致,消除系统误差.

3、指示剂要保持新鲜.

4、三乙醇胺等掩蔽剂要正确加入,防止指示剂的封闭效应.

5、当然,器皿的洗涤、溶液的移取、滴定的速度和终点的控制也十分必要.
