To solve above problems, it is suggested to advance parti-colored communication channels, in sure communication targets and subjects, bring message to light as soon as possible, co-optation opinions of local people, building a institutional channel for risk communication; it possibly becomes the risk communication tool which full of environmental democracy if consensus conference could reinforce it's representatives of citizen panel, legal force of conclusion report.

根据上述成因本研究认为发展多元化讯息发布管道、确定沟通对象与议题、尽早公开资讯、吸纳当地民众意见、建立制度化的风险沟通管道等可做为政府风险沟通之参考依据；而公民会议若能强化公民小组之代表性与结论报告的法律效力，则可能成为具备环境民主精神之风险沟通工具。

Power control is one of the necessary key techniques for mobile communication systems. The frame structure of WCDMA communication system is different from those CDMA commination systems, which have only one type of traffics. In addition, multimedia services have different quality of service requirements. Thus the power control for WCDMA communication system will different from that in narrow band CDMA communication systems.

功率控制是CDMA移动通信系统中必不可少的关键技术之一，WCDMA移动通信系统的结构不同于单一业务的CDMA移动通信系统，且多媒体业务有不同的服务质量要求，因此，WCDMA多媒体移动通信系统中的功率控制将不同于单一业务的CDMA移动通信系统中的功率控制。
