  1. The positive is that as a substitute of old channel or a part of the new channel shiplock maintains the continuation of channel and makes possible the channel free from navigational obstruction and waterway transportation progress. the negative is that shiplock at the same time brings some problems to waterway transportation, such as the long time passing through shiplock, the piling up of vessels, making less other ' s benefits and making more other ' s costs, making conditions and forms of transportation change, making more complicated the waterway transportation safety management and navigation order keeping, and adding up transportation costs

    在經濟學意義上，船閘具有正負外部性，正的外部性為，船閘作為原航道的替代物或新航道的一部分，保證了航道的連續性，為保證航道暢通、航運發展提供了可能；負的外部性為，船閘同時給航運帶來了一些問題，如船舶過閘時間長、船舶積壓，引起他人效用的減少和成本增加，以及運輸組織條件、方式改變，使水上交通安全管理和船舶航行秩序維護更加復雜，增加運輸成本。

  3. This paper goes on with analysis of the phased array radar calibration theory and compare of different schemes, then the best is adopted. 2 mhz digital circuit mainly composed of dds ( direct digital synthesis ) chip, which carries out the shift of the phase and the limit of the amplitude, has been designed and debugged successfully. it is used to substitute for the conventional phased shift circuit and amplitude limiting circuit which work at the radio frequency, so the all - digital transmit channel of phased shift array radar is achieved

    本論文研究的重點是：針對傳統相控陣雷達系統收發（ t r ）組件中的移相和限幅功能均在射頻段完成，大膽利用直接數字合成（ dds ）晶元組成頻率在2mhz左右的數字電路代替傳統相控陣雷達在射頻段進行移相和限幅的電路，從而組成全數字發射通道，使對相位和幅度的控制和調試更方便快捷，並設計具體的電路驗證此方案的可行性。
  4. To the issues that ipsec ca n ' t work with nat and multicast very smoothly and ipsec could n ' t also solve qos problem, combined with the national high - tech project of 863, the author has put forward the following viewpoints in the research of the security architecture model of ip layer : as to ipsec ' s working with nat, the author has proposed a scheme of using udp encapsulation along with configuring ipsec tunnel by dhcp and substituting ah with esp null encapsulation ; as to ipsec ' s working with the multicast, the author has proposed that combined with key management using complete binary tree, ipsec security process using espv3 and ahv2 can cooperate with multicast smoothly in multicast environments ; as to solving qos, the author has proposed a scheme of using two - level classifying and two - level scheduling with encryption scheduler and forwarding scheduler. the author has pointed out that combining ipsec with pki can make ipsec more flexible and more practical. based on the previous researches, the author has made an analysis of security risks of ip layer

    在ip層安全體系結構模型研究中，針對ipsec在與組播、 nat協同工作等方面存在的問題以及ipsec不能很好解決qos等方面的問題，作者結合國家863高技術項目的研究提出了解決方案：在nat協同工作方面作者提出了採用udp封裝、配合使用dhcp配置ipsec隧道並用espnull封裝代替ah的方案；在與組播協同工作方面作者提出了基於espv3和ahv2的ipsec組播安全處理以及基於完全二又樹的組播密鑰管理的方案；在解決qos問題方面作者提出了採用分類器1和分類器2的兩級分類以及具有加密調度器和轉發調度器的兩級調度的技術方案；同時作者提出了ipsec與pki技術緊密結合，能使ipsec安全通信更加靈活和方便實用。
  5. Harq, amc and multi - code in hsdpa have replaced the osvf and power control technology in release99 protocol. in a short time, the ues who are near to nodeb can be allowed to transfer more data with some higher modulation method. it increases the throughput of certain ues, as well as the throughput of a cell

    Hsdpa採用harq 、 amc 、多碼傳輸等技術替代release99中物理通道使用的變擴頻因子（ osvf ）和功率控制技術，使靠近nodeb的用戶在短期內可以得到更多傳輸數據量和更高階的編碼調制組合，提高用戶吞吐量，使系統從短期的變化中受益。
