  1. To add " there are many loopholes in the operation and sales practices of telecommunications service providers, " after " that, as " ; to add " and such complaints from the public are often not followed up effectively by government departments, " after " in recent years, " ; to add " stipulate corresponding penalties " after " to cover pay television, " ; and to add " ; furthermore, as the hong kong housing authority has signed agreements with pay television operators, these operators can enter the buildings to set up and maintain communal aerial systems and can deploy front - line promoters to approach the residents to sell other various commercial services, using the provision of exclusive maintenance and supply services as a selling point and adopting unscrupulous means to entice or mislead the residents into signing an agreement with them, causing great disturbance to the residents ; in this connection, the government must adopt measures to combat such sales malpractices, take the initiative to inform public rental housing tenants of the rights and responsibilities of the operators and, when the operators resort to malpractices or malpractices are reported by residents, take immediate action to investigate the matter and issue warning to and penalize the operators concerned ; the government must also review the problem of inequity in accessing system information by consumers and the telecommunications service providers, whereby consumers have no means or right to obtain true and accurate information about the systems that they are using and can only pay the fees according to the volume, system and time slots of their calls shown on the records provided unilaterally by the service providers, and in case of queries about such information, the decision of the service providers prevails and there is no channel for the consumers to dispute or verify ; to this end, the government should expeditiously study how to ensure that consumers have the rights to know, choose, verify, appeal and claim for compensation in the provision of telecommunications services including pay television, local and cross - boundary telecommunications and internet services " after " in the contracts "

    在"鑒于"之後加上"各訊服務提供者的營運和銷售存在不少漏洞, "在"不斷增加, "之後加上"而市民的投訴又往往得不到政府部門的有效跟進處理, "在"收費視, "之後加上"訂相應的罰則, "及在"標準合約條款"之後加上"此外,由於香港房屋委員會與收費視營辦商簽訂協議,該等營辦商可進入大廈鋪設及維修公共天系統,並調派前銷售人員,以獨家提供維修及供應服務作為招徠,住戶推銷其他各種商業服務,以不當手誘使或誤導住戶與他們簽約,對居民造成很大困擾就此,政府必須採取措施打擊上述違規營銷的手,並主動告知公屋住戶該等營辦商的權責范圍,遇有營辦商作出違規的行為或居民舉報營辦商的違規行為時,須立即追查,並有關營辦商發出警告及作出處分政府亦須檢討現時消費者與訊服務供應商所獲系統資訊並不對等的問題,即消費者從及權得知他們所選用系統的真實資料,令他們只能按服務供應商單方面提供有關通話量通話系統及通話時段的記錄繳交費用,遇有消費者質疑上述資料時,往往只由服務供應商作最終決,消費者從申辯或查證就此,本會促請政府盡快研究如何就各類訊服務包括收費視本地及跨境訊網際網路等的提供,確保消費者享有知情權選擇權覆核權投訴權及索償權" 。

  5. It can be used in any complex environment, can locate all paths from transmitter to receiver which avoid redundant calculation, and it is a standard 3 - d forecast model ; in addition, it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently, the proagmme can back - search the virtual fountain tree when it is running. these operation increase the calculate speed and it result in the higher receive efficiency and precision. the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models. the comparsion result indicate the new model is a better model

    它可應用於任何復雜的傳播環境中,能找到發射機到接收機之間的所有波傳播路徑而須冗餘的計算,是一種準三維的預測模型;另外,從本質上講,它仍然是一種基於鏡像理論的點對點的射跟蹤,所以它須進行接收測試;而且由於採用了反演算,運用數據結構中多叉樹的概念,先確需要計算的場點位置,找出所有能從源點到達場點的射,並且可一次性建立一個虛擬源樹,以後每次的計算只要通過對該樹進行後序遍歷即可,大大提高了運算速度,因而有較高的接收效率與精度。本文對該模型進行了相應的模擬,並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射跟蹤確性模型的預測結果進行了比較,結果表明了該模型的優越性。
