1. wrappers,drx和prx区别?
回答如下:DRX和PRX都是无线通信中的概念,但它们针对的是不同的方面。
DRX是Discontinuous Reception的缩写,意为“间断性接收”。在LTE中,DRX是一种省电机制,用于延长终端设备的电池寿命。当终端设备没有数据要发送或接收时,它会进入DRX模式,即停止接收信号,以节省电力。当有数据要发送或接收时,终端设备会退出DRX模式,重新开始接收信号。
PRX是Power Control的缩写,意为“功率控制”。在无线通信中,PRX是一种控制发射功率的技术,用于确保信号能够在合适的范围内传输。通过PRX技术,发射端可以根据信号强度来调整发射功率,以确保接收端能够稳定地接收信号,同时避免过度消耗电力和频谱资源。
因此,DRX和PRX是两个不同的概念,它们分别应用于不同的领域,其中DRX主要用于省电,而PRX主要用于信号传输控制。
2. centos怎么搭建ftp?
1. 安装FTP服务器软件
在CentOS系统中,常见的FTP服务器软件有vsftpd、proftpd、pureftpd等,这里以vsftpd为例,在终端输入以下命令进行安装:
```
yum install vsftpd
```
2. 配置FTP服务器
首先,备份vsftpd配置文件,然后打开vsftpd配置文件:
```
cp /etc/vsftpd/vsftpd.conf /etc/vsftpd/vsftpd.conf.bak
vi /etc/vsftpd/vsftpd.conf
```
根据需要对下列选项进行设置:
```
anonymous_enable=NO #禁止匿名访问
local_enable=YES #允许本地用户访问FTP服务器
write_enable=YES #允许FTP用户上传文件
local_umask=022 #本地用户上传的文件默认权限
dirmessage_enable=YES #允许FTP服务器显示目录信息
xferlog_enable=YES #允许FTP服务器记录传输日志
connect_from_port_20=YES #使用20端口传输数据
chroot_local_user=YES #限制FTP用户在主目录下操作
listen=YES #开始监听FTP服务请求
```
保存并退出配置文件。
3. 配置FTP用户
首先,创建FTP用户的密码文件(以example为例):
```
htpasswd -cd /etc/vsftpd/passwd example
```
然后指定FTP用户的主目录,这里以/home/example为例,在终端输入以下命令:
```
mkdir -p /home/example
chown -R example:example /home/example
```
4. 启动FTP服务
在终端输入以下命令启动FTP服务:
```
systemctl start vsftpd
```
FTP服务启动后,可以使用FTP客户端登录验证FTP服务器是否正常运行。
3. 关于棒棒糖的英语故事?
1.candygram (或candy cane gram) 棒糖传情
某学校活动:学生先上超市买下大包装的棒棒糖,例如每根一毛钱。再拿到学校里,每根卖两毛五。假如学生买上一根棒棒糖,然后要求附上小卡片,请人送到心仪的同学那里去,表达情意,就要五毛钱。
Telegram叫电报,candygram就叫“糖报”吧,呵呵,也或“棒糖寄语”,或“棒糖传情”~~
字典上的解释是:
candygram (plural candygrams):A box of candy, delivered with a greeting or other prepared message。
递送的、附有问候或其它写就信息的一盒糖果。
类似的,flowergram,就是鲜花传情吧~~ 幻想着啥时候有flowergram送到办公室里来^_^
美国有家鲜花递送公司,就叫flowergram。

2. brain candy 脑轻松
Brain candy describes an experience that is enjoyable because it stimulates the mind pleasantly, but doesn't actually make it work, usually in reference to light and fluffy books, movies, TV shows, and other entertainment.
Brain candy(脑轻松)指让大脑轻松愉快的体验。这种体验能够刺激大脑、让其感到愉悦,同时又不会让大脑处于工作状态,多指轻松简单的书籍、电影、电视节目以及其他的娱乐形式。
For example:
No one ever called Star Trek great drama, but it makes pretty good brain candy.
从来没有人说过《星际迷航》是一部伟大的作品,但它作为一部轻松娱乐的片子还是很好的。
3. eye candy 养眼花瓶
A common slang term for visually appealing persons or effects used to draw mass attention is eye candy. The implication is that they are eye-catching in a superficial fashion. Like actual "candy", this addition is seen to be neither nutritious nor substantial, but rather provides a potentially addictive appeal which will sustain the attention of a wider audience, possibly despite their better nature.
英语俚语中通常用eye candy这个词来指代在视觉上颇具吸引力的人或者能够吸引人眼球的视觉效果,我们暂且译为“养眼花瓶”。也就是说,这些人或者视觉画面从表面来说很具有吸引力。就像candy(糖果)一样,既没有什么营养价值,也没什么实质内容,而只是能够引起更多人关注的兴趣。至于他们本质如何,则通常少人在意。

The term may have been originated by interactive videodisc, user interface designers working at INTERAC Corp. in 1983. Their work integrated text, audio, graphics, photographic images, and video into a seamless presentation. The "eye candy" referred to visually appealing images supporting the overall message.
Eye candy这个词初见于1983年,是由INTERAC公司的互动视盘、用户界面设计师首先使用的。他们将文本、音频、图标、照片以及视频融合成一个整体的展示界面,而eye candy指的就是为上述整体信息提供支持的视觉画面,这些画面通常都会设计得非常吸引人眼球。
The term is also used to refer to actors or actresses perceived to have been cast primarily for the visual enjoyment of the audience. Various novels, articles, and stories have used this slang term to show a physical attraction one person has toward another.
Eye candy也可以指代那些仅仅用来让观众赏心悦目的演员(通常被我们称为“花瓶”)。很多小说和文章都曾经用这个词来表现一个人的外在吸引力。
与之类似的一个词是“man candy草包美男”
Man candy is a man who is superficially attractive to look at or a man who has an attractive appearance but who may be vapid and lack substance.
草包美男指外表很吸引人的男子;或者徒有迷人外表,但其实很无趣又没有内涵的男子。
4. 用两三句英语介绍饺子?
Dumplings are a traditional Chinese food. In northern China, they are always indispensable during the Spring Festival.
2. Jiaozi is one of the most important foods for Chinese people during the Spring Festival. Because the shape of dumplings is similar to ancient Chinese gold and silver ingots, dumplings symbolize wealth. According to tradition, the whole family gets together to make dumplings on New Year's Eve. They would hide a coin in one of the dumplings. It is said that whoever eats that coin will have good luck in the New Year. Dumplings are also popular in other traditional Chinese festivals, so they are undoubtedly a part of Chinese culture and traditional culture.
3. Making dumplings requires teamwork. Usually all family members are involved. I began to learn how to make dumplings at home when I was young. Most Chinese learn to make dumplings when they are young, so almost every Chinese can do it. I am good at making dumplings, especially the wrappers. You know, making dumpling skins is the most difficult part of making delicate and delicious dumplings.
4. When we say goodbye to friends or family, we usually eat dumplings. I guess that's another tradition and another reason why dumplings are such an important part of Chinese culture.
