  1. Therefore, how to get the near - field sampling data quickly and accurately is of great importance for improving the efficiency of the near - field measurement technique

    如何在保證精度的前提下，加快近場數據采樣的速度是一個值得研究的理論和實際問題。它對提高近場測量的效率有重要的意義。
  2. An significant symbol has been used to determine the technique of 3 - d discontinuities network modeling of rock mass is good or not, which is to check whether the model can reappear the reality situation of rock mass or not, in order to make the 3 - d network model to meet the need of the actual rock engineering, the methods to verify the result of the modeling are required, one of the method to be used is to compare the figures between the section of the numerical model and the sampling window of in - situ model, the second method to be used is verify the data set between the numerical model and field data, only if the verification obtained a good precision, then the model can be considered as a efficiency model, and it can be applied into the actual rock engineering

    摘要巖體隨機不連續面三維網路模擬技術成熟與否的一個重要標志就是最終的網路模型是否能夠較真實地再現巖體的實際情況，為了使三維網路模型的結果能夠真正地應用於實際工程，就必須對模擬的結果進行必要的檢驗，檢驗的辦法就是將模擬出的模型剖面圖形與原型測量窗口的圖形進行圖形對比，或者將原型的觀測數據與模型的測試數據進行數據對比，當這種檢驗達到精度時，模擬出的模型為有效模型，可以投入工程實際應用。
  3. With multi - ccd and multi - computer system, video and sampling synchronization technique in lan adopted, real - time measurement of large - scale flow field was achieved. velocity distribution of the flow field with an area larger than 1000 m2 can be measured in 20 seconds

    採用多ccd攝像機和多臺計算機、視頻信號同步、局域網同步等技術，首次實現了大范圍流場的實時測量，在20秒鐘之內測量1000m2以上的流速場。
