  1. Double data rate - synchronous dram, ddr - sdram

    雙倍數據傳輸率
  2. The main purpose of this paper is to study crack growth rate of a class of nonlinear viscoelastic materials under the condition of constant load and small - strain. in this paper : the new test program is raised by referencing the existing test programs and by our trial and error ; in the new test program, facilities involved in the nonlinear viscoelastic crack tests are relatively few, the test process is relatively simple and the data obtained from the experiments are credible. on this basic, the calculation of j integral of nonlinear viscoelastic double cantilever beams specimens and the parameter of fracture work of corresponding nonlinear viscoelasticity are derived

    具體成果包括： 1 、證實了雙懸臂梁試件用於非線性粘彈性裂紋擴展實驗研究的優點：雙懸臂梁試件在實驗中能觀測到的擴展過程持續時間比較長，在計算j積分時，計算方法簡單； 2 、得到了改性聚丙烯材料用於非線性粘彈性裂紋擴展實驗的兩種有效的試件構形和相應的試件尺寸；採用不斷改善夾具的方法使得加載穩定； 3 、經過連續四個多月的時間得到了一組有用的實驗數據； 4 、得到了裂紋長度與時間的關系、裂紋擴展速度與時間的關系、裂紋擴展速度與裂紋長度的關系。
  3. Reducing the data rate by one - half will double the duration of each symbol interval

    將數據率減少一半，能使每個符號間隔的持續時間延長一倍
  4. From computer directly, the device can get data from two specifically wav files which have double channels of data, and whose sample rate are 44100, and whose resolution are 16. then it makes digital signals convert into anolog signals and amplify them at the same time. at last, according to actual need, it can supply continuous anolog audio output of enough power and high fidelity at different speed

    該設備可以直接從計算機獲取兩個雙聲道、 16位解析度、 44100hz采樣率的wav （ waveform ）聲音文件的數據，並同時將兩個聲音文件的數據進行數模轉換和信號放大，最終以能滿足實際生產需求的較高速率連續地輸出具有足夠驅動能力和高保真度的模擬信號，為終端高速磁帶復錄子機提供穩定可靠的音源。
  5. Double data rate

    雙數據率
  6. Traditional design ways already ca n ' t give a reliable solution for these systems, especially when ddr ( double data rate ) memories come into fact. high - end designers must pay special attention to the signal integrity problems

    尤其是隨著ddr （ doubledatarate ）存儲器等高速器件的誕生，傳統的電路設計方法已經無法保證系統的可靠性，信號完整性分析已經成為高級電子設計人員非常關心的問題。
  7. The phase diagram of completely mutually soluble double - fluid system needs not only many sets of data, but also map work curve of refract rate - composition, data processing and mapping larger workload

    摘要由於完全互溶雙液系平衡相圖的繪制需要許多組數據，而且要繪制折光率組成工作曲線，數據處理和繪圖工作量較大。
