如何合并系统与软件

正Q:我原来将系统安装在C盘,所有的应用程序安装在D盘中,现在想将D盘中的软件合并到C盘,最后克隆到一块单分区的SSD硬盘中。请问有什么方法可以实现?A:这种情况下,如果你不想重新安装系统,则需要将D盘中的大型软件(如Office)卸载掉,将一些绿色软件直接拷贝到C盘,然后再进行克隆,这样就不会出现软件错误了。如果SSD硬盘容量大,也可以将SSD硬盘分成2个分区,然后直接将原硬盘的C、D盘克隆至SSD硬盘即可。     

Effect of water pretreatment on CO<Subscript>2</Subscript> capture using a potassium-based solid sorbent in a bubbling fluidized bed reactor

A bubbling fluidized bed reactor was used to study CO₂ capture from flue gas by using a potassium-based solid sorbent, sorbKX35 which was manufactured by the Korea Electric Power Research Institute. A dry sorbent, sorbKX35, consists of K₂CO₃ for absorption and supporters for mechanical strength. To increase initial CO₂ removal, some amount of H₂O was absorbed in the sorbent before injecting simulated flue gas. It was possible to achieve 100% CO₂ removal for more than 10 minutes at 60°C and a residence time of 2 s with H₂O pretreatment. When H₂O pretreatment time was long enough to convert K₂CO₃ of sorbKX35 into K₂CO₃ · 1.5H₂O, CO₂ removal was excellent. The results obtained in this study can be used as basic data for designing and operating a large scale CO₂ capture process with two fluidized bed reactors.

多种油脂的脂肪酸组成分析

制备出一种柱效高、成本低的复合型色谱柱。并利用醇解法进行了脂肪酸甲酯化，用气相色谱法测定了乌桕脂、棕榈油、可可脂、鱼油及自制类可可脂的脂肪酸组成。     

开机日志错误

正Q:我的Windows 8系统中之前安装了百度杀毒,卸载后发现开机日志中总有错误显示"Bhbase,Bnbase,Bndef,Bprotect",开机速度变慢。请问这该如何处理?A:从http://tinyurl.com/mkapkk5下载安装微软的Autoruns工具,然后搜索Bhbase、Bnbase、Bndef及Bprotect,找到后直接将这些项删除即可。     

电脑协助背唐诗

正TC调用Everything目录Q:我一直使用Everything搜索硬盘中的文件,找到后双击,默认就会用资源管理器打开,现在我想默认用Total Commander(TC)来打开。请问如何才能实现?A:首先需要你的Everything版本在V1.2.0 Beta以上。版本确定后,退出Everything,接下来打开其安装目录下的Everything.ini文件,按如下格式添加两行到文件末尾:     

PPT也玩旋转跟随

正很多人在PPT中做路径动画时,常常会遇到这样一个问题,就是物体不能随着运动路径的曲率自动发生旋转。但是这在Flash等专业动画软件中却很容易实现。那么,在PPT中如何实现呢?此处以笔者工作中遇到的演示一架飞机做"俯冲—拉起"运动为例,探究该演示功能的实现过程。     

手机无法收发短信

正休眠手机无法连接Wi-Fi Q:我使用的是Android 4.0版手机,发现手机只要进入休眠状态,Wi-Fi就会自动断开,这时候的微信等软件都会自动使用数据流量。请问这是什么原因?A:你的手机可能设置为休眠状态下断开WLAN连接了。可做如下设置进行修改:打开手机设置,进入"WLAN"设置,点按手机的菜单键,选择"高级"项,再点开"在休眠状态下保持WLAN连接",设置成"始终",保存设置即可。     

多张图片合并成PDF文档

正Q:我有多张PNG格式的图片,现在想把这些图片合并成一部PDF电子书.请问有没有简捷的方法实现?A:如果你的系统中安装有Word程序,可以通过图片插入功能先将这些PNG图片插入到文档中,然后另存为PDF格式文件即可。此外,你还可以使用专门将图片转换成PDF格式文档的小工具——Free Pic2Pdf,借助这款小工具也可以方便地将图片转换成PDF格式的文档。平时在使用电脑的过程中,经常会遇到格式转换的问题,而有些时候可能不需要另外找软件就可以达到目     

Catalytic coal partial gasification in an atmospheric fluidized bed

The coal partial gasification catalyzed by limestone, sodium carbonate and dolomite was studied using a bench-scale atmospheric fluidized bed in the presence of air and steam at 900 °C. The effects of limestone, sodium carbonate and dolomite on composition, heating value, gas yield of product gas and carbon conversion in the catalytic coal partial gasification have been examined. The experimental results show that the catalysts can effectively improve the gas quality, the heating value and the gas yield of product gas and carbon conversion. The catalytic effect of sodium carbonate is better than that of limestone and dolomite. The increase of limestone loading can enhance the quality of product gas, such as the content of combustible gas, the high heating value and the gas yield, during coal partial gasification.
