  1. Aimed at the feature of great fluctuation of water flow - rate in rivers and taking the monthly average flow - rate at low water with 90 % guaranty in recent ten years as design flow - rate, the permissible amount of major pollutants discharged into yellow river by lanzhou namely the stochastic environment capacity of waters, was determined by using a stochastic computation mode on the basis of lognormal distribution theory

    摘要針對河流量變化大這一特點,採用以對數正態分佈為指導的隨機計算模式,以近十年90 %保證率最枯月均流量為設計流量,確定黃河蘭州段主要污染物的排污量,即隨機環境量。
  2. Researches the basis watermark managing works particularly and systemly. there are many works to do on watermak technology except watermark embedding and extraction arithmetics such as the watermark choosing, encoding, modulating, demodulating and the watermark capacity. these prior and ultimate works ensure that the arithmetic is brought into effect. just understanding these, this paper analyses and researches the basic watermark theoretics in many pages. it brings forward chaos modulation on watermark modulating, brings forward chaos permuting on image permuting, introduces bch encoding on letter watermark processing and discusses the approximate estimate of the watermark capacity in dct domain and dwt domain by applying the current communication theoretics. there works not only extend ways for the later work but also are significative on watermark research

    全面系統地研究了印信號的處技術數字印技術除了印嵌入和提取的演算法外,還有多工作需要做,如印的選碼、編碼、調制、解調、能量的確定等等,這些預處和后處工作是演算法有效實施的必要保證,正是基於這樣的認識,本文利用較大的篇幅對印的基本知識進行了詳細的分析和研究,在印的調制方面,提出了混沌調製法;在圖像印的置亂方面,提出了混沌置亂法;在文字印的處上,引入了bch編碼;在量分析方面,結合現代通信,對圖像在dct域和小波域內的量估算進行了詳細的探討,這些工作不僅為本文後期工作鋪了道路,而且對數字印的研究具有重要的意義。
