That is to say,the IPTV architecture should carry a myriad of services and technologies. In light of current telecom/TV status,the IPTV architecture can be set up on the convergence of the three networks to deliver comprehensive services and make Live TV,TV on Demand (TVOD),and Time-shifted TV services accessible on one platform. It also supports local and cross-regional user and service certification,provides EPG and smooth TV images and guarantees secured content as well.展开更多

At present, China's water resources have become the three strategic resources, but there are still many problems in the development, utilization and management of water resources. Therefore, the status quo of technological development in the field of hydrology and water resources in China, analysis, application and popularization of technologies in the field of hydrology and water resources, promotion of technological intelligence and timely updating of hydrology and water resources in the research field, reduction of water resources consumption, alleviation of water resources pressure and protection of water resources.展开更多

In this paper, the reason why old bridge is damaged, the requirements for strengthening technology and construction plan for bridge strengthening are analyzed in detail, hopefully, there are some useful proposals provided for old bridge transforming.展开更多

Through analysis, a calculation method of heat dissipation of conventional electrical equipment such as high-voltage switchgear, low-voltage switchgear, capacitor compensation cabinet, and high-power heating equipment such as transformer, frequency converter and heater thyristor control is introduced. Combined with practical engineering experience, a scheme of electrical equipment layout, HVAC design and layout in box-type substation is recommended. The analysis and introduction of this paper will have certain guiding significance for the design of box-type substation, HVAC and air conditioning of substation in practical engineering.展开更多
