查询词典 directed line

The result showed that the strong storm followed by mesoscale squall line was primary cause of strong sandstorm producing, steps and ladders short wave trough of 500 hPa was great criterion triggering system for the mesoscale squall line producing, the essential dynamic condition was provided by distortion field and the mesoscale low pressure of 700 hPa for the strong sandstorm forming and maintaining in mid-west of Hexi Corridor, the deep vertical circulation development condition was basic power that urged squall line to occur and sand dust to curl up, which was provided for the deep convection development by superimposition of lifting movement before ground cold front and ascendant current of secondary circulation in upper air jet entrance region, temperature and the barometric gradient around the cold front was enlarged by enhancement of ground thermal low and temperature diurnalvariation of afternoon, by which essential thermal energy unstable condition was provided for the gale and strong sandstorm eruption, the strong sandstorm appeared in downstream of -200 m^2s^(-2) center of vertical helicity, the vertical helicity had good instruction significance for development of squall line and landing region of sandstorm, the mesoscale squall line occurred in unstable stratification, basic condition of potential energy transforming as kinetic energy was provided by strong unstable stratification for the strong sandstorm forming and developing.

结果表明：中尺度飑线所伴随的强风暴是产生强沙尘暴的主要原因；500 hPa阶梯短波槽是中尺度飑线产生的大尺度触发系统，河西走廊中西部700 hp变形场、中尺度低压为强沙尘暴形成和维持提供了必要的动力条件；地面冷锋前上升运动与高空急流入口区次级环流的上升气流的叠加，为深对流发展提供了深厚的垂直环流发展条件，是促使飑线发生和沙尘卷起的基本动力；地面热低压的加强和午后气温的日变化加大了冷锋前后的温度和气压梯度，为大风、强沙尘暴爆发提供了必要的热力不稳定条件；强沙尘暴出现在垂直螺旋度为－200平方公尺/s^2中心的下游，垂直螺旋度对飑线的发展和沙尘暴的落区具有较好的指示意义；中尺度飑线发生在不稳定层结内，较强的不稳定层结为强沙尘暴形成、发展提供了位能转化为动能的基本条件。

A method for carrying out terminal management based on EPON includes connecting unit management system on optical line terminal based on EPON and setting up network management channel between them and between optical line terminal and each network terminal, carrying out analysis on message by optical line terminal when network management protocol message is sent to optical line terminal by unit management system, retransmitting message to network terminal by set up operation-maintenance channel when network protocol message is aimed at network terminal and retransmitting message reported from network terminal to unit management system by optical line terminal.

一种对基于EPON进行终端管理的方法，在基于EPON的光线路终端上连接设备管理系统，在它们之间建立网络管理通道，并在光线路终端和各网络终端之间建立承载在操作管理维护协议层上的网络管理通道；设备管理系统向光线路终端发送网络管理协议报文时，光线路终端对该报文进行解析，如果是针对网络终端的网络管理协议报文，则将该报文通过所建立的操作维护通道转发给该网络终端；网络终端向设备管理系统上报的消息，由光线路终端转发给设备管理系统。

As for the film I went to see today, it's something I've never seen before and is called Delicatessen. Directed by Marc Caro and Jean-Pierre Jeunet, who also later directed The City of Lost Children together. I certainly like The City of Lost Children and Jean-Pierre Jeune's Amelie is definitely one of my favourite films.

但是既然要看就要看没看过的，因此看的是黑店狂想曲，是由马克卡罗、尚皮耶居内共同导演，他们也是后来我很喜欢的惊异狂想曲的导演，尚皮耶居内后来还导了我的爱片之一的艾蜜莉的异想世界。
