Korea put the company at electric power control device - the general type STR (thyratron thyristor power controller) CPU upgrade to system memory type, and early in 2003 to develop cutting-edge new product type constant current, constant voltage type collectively referred to as STR (may silicon-controlled thyristor power controller) the inherent brand. In 2000 to develop the motor starting device - soft starter motor new products and the inherent SMC brand available at the area of power control both at home and abroad alike. Market in 2000 and 2002 patent SSC (packaged solid-state thyratron power controller), as well as sales from the company since its inception back filter with Pulse Timer and other products in the same trade firmly occupy The largest market. Also in 2002 the development of the supply of silicon wafer characterization equipment and sub-Plasma Ion Plating with the most cutting-edge power supply devices and so on, so if the company has high-speed development.

本公司在韩国把电炉电力控制装置-一般型STR升级为CPU系统内存型，与2003年初新开发的尖端产品恒电流型、恒电压型统称为STR 这一固有品牌。2000年开发电动机启动装置-电动机软启动器新产品并以SMC这一固有品牌面市，在电力控制领域受到国内外的一致好评。2000年面市并2002年取得专利的SSC(封装固态闸流功率控制器)，还有从公司创立初期销售至今的 back filter 用 Pulse Timer等产品在同行业中牢牢占据着最大的市场。2002年又开发供应硅wafer分段定性装备及Plasma Ion Plating用最尖端动力供应装置等，因此公司具备了高速发展的依据。

Video server sends a RSVP message to reserve resource for client, and the system calculates and analyses QoS parameters using control information of RTP/RTCP packets and ICMP Echo request message, and controls the transmission grade by corresponding strategy to ensure network QoS, which enhances the system reaction to network condition and stabilizes the throughput and solves the problems of data transmission and using bandwidth fairly between multicast data and other kind of data when network is congestible and unstable.

整个模型系统主要由视频服务器、路由节点和客户端构成，通过RSVP协议进行资源预留协商，并在传输过程中利用RTP/RTCP包中携带的控制信息结合ICMP Echo请求报文提取QoS参数，对其进行分析判断，采用相应策略对传输级别进行实时控制，保障了网络QoS，提高了系统对网络状况的反应速度，降低了传输速率的波动性，较好解决了网络拥塞和不稳定时数据的有效传输以及与其他数据流公平占用带宽的问题。

The results showed that the flow reattachment distance in the lee side of various dune models are ranged from 4.8H to 10.8H depending on different stoss slopes, the maximum of flow reattachment distance was found in the lee side of the transverse dune with a 15° stoss slope angle.

实验结果表明，当来流风速垂直于沙丘脊线时，沙丘背风侧的气流重附距离介于4.8H～10.8H之间，最大重附距离出现在迎风坡坡度为15 的沙丘背风侧；沙丘迎风坡坡度是控制背风侧气流重附距离的主要因素，而自由风速对气流重附距离的控制作用较小。

The Telecom service has some typic characters , such as complexity in business category , high quantity level , service control complicacy etc.

电信业务具有种类繁多、数据量大、业务控制复杂等特点，工作流管理是实现业务过程控制的重要技术。

According to different types of abnormal pressure,computation model for quantitative control on the abnormal pressure was set up to meet the needs of efficient and safe drilling in oil-gas fields.Some important parameters were calculated that include reasonable shut-in time,maximum flowing yield and the best flowing time of the injection wells,and reasonable bottom hole flowing pressure,extra oil production and stimulation moment of the production wells.The quantitative computational methods of them were derived.Three methods were applied to one undrilled adjustment well T1 in certain oil-gas field achieving quantitative control to the abnormal pressure in the adjustment well.
