解釋
隨機圖形-
Then the deficiencies of dfe ( dorp from end ) mechanism in a router ' s input queue are studied. after that, the thesis figure out that red ( random early detection ) active queue management mechanism can be used to prevent networks from congestion collapse
接著，文章重點分析了現有網路節點中所採用隊尾丟棄策略的不足，認為只有採用隨機早期探測（ randomearlydetection : red ）這種動態隊列管理機制才能有效避免網路出現擁塞。 -
For the anticounterfeiting of printings ( such as certificate ), the existent many ways ( such as rainbow holograms ) are not available as the need for special use : anti - distortion and anti - copy. basing in the double - random - phase transform, this article puts forward a new way that two - dimensional bar code is used as anticounterfeiting label with anti - printing ? scanning and anti - damage properties. the major job are : ( 1 ). basing in the ascii codes, numerals and alphabets are encoded and subsequently transformed into two - value bar code matrix figure. later, using amplitude - based double - random - phase transform, the enciphered gray scale figure is formed. by computer simulation ( 4f system ) and printing as well as scanning ( 20 times ), we get the result that the gray scale figure with little miscoding rate ( 0. 0026 ) by “ matrix expanding way ”
本文主要開展了以下三項研究工作: （ 1 ） .用自定義編碼方案，將數字和字母（ ascii碼）轉換成二值條碼圖;對該圖形進行振幅型雙隨機相位加密變換，得到原信息的加密灰度圖;通過4f光學系統計算機模擬和列印-掃描實驗，證明本文提出的「矩陣擴展法」灰度圖具有較小的誤碼率，對於20次列印-掃描實驗，誤碼率不大於0 . 0026 。 -
As explained by the following figure, gas in low pressure and low density will alter the light that passes through it. it is because the gas will absorb light at some particular wavelengths and re - radiate it in random directions. thus, after passing through the low pressure gas, the spectrum of the original white light will have dark lines, called
並不是所有光譜都是黑體輻射光譜，如下圖所示，低壓下的低密度氣體會改變通過它們的光線，這是由於氣體會吸收特定波長的光波並隨機向不同方向把所吸收的光線輻射出來，結果光線在通過低壓氣體后，原本的光譜上會出現很多稱為 -
The aim of this paper is to propose a new method that is creatively based on the character of irrational number, the digital have no limit and no period. this article research some algorithms such as expending the irrational number to the arbitrary figure, initialing data and generating random number
本文提出了一種新的產生隨機數的方法，創造性的運用無理數數字無限不循環的特性，論文研究涉及將無理數展開到任意位、通過計算機位數決定數據范圍並分組初始化數據、生成隨機數等主要演算法，主要用c和vb語言實現。 -
( 2 ). we consider fully phase double - random - phase way to form gray scale figure. by computer calculation and experiments, we get the result that the miscoding rate of decoding is little ( 0. 0174 ) even if 1 / 4 area of gray scale figure is damaged
通過計算機模擬和列印-掃描實驗，證明在面積破損1 / 4的條件下，相位型的誤碼率仍較小，為0 . 0174 。
