  4. The usual measuring method, that is, to use the water temperature of 1 meter under water surface to adjust the spinning speed of the sounding device, will result in greater measuring errors. this article put forwards the mathematical model of water temperature with the vertical water temperature that was measured at the deepest site of six sections. after adjusting the sounding device w

    本文依據實測的6個斷面深泡點處的垂線水溫建立了水溫輔助測深數學模型，依據該模型即可得到保證回聲儀測深精度的水溫值，用該水溫值校正回聲儀后，便可得到斷面對應于各起點距處的水深值，從而解決了丹江水庫三維模型建立的關鍵問題。
  5. The 3d model needs three parameters, among them, the distance from the dam and the distance from the starting point of the section can be measured directly, and the depth of the water corresponding to the distance from the starting point of the section can be measured by the sounding device. however, because the reservoir is very deep, the measuring error of the water depth is greater

    而建立其三維模型需要三個參量，其中距壩里程、備斷面起點距可直接測得，而對應于各起點距的水深值因丹江口水庫較深，按通常的方法使用回聲儀測深，即以水下二米處的水溫校正回聲儀的轉速來測深有較大誤差。

    灌區特設量水設備水量監測誤差分析
  7. The millimeter has the largest frequency band and the highest velocity of communication, but it has the highest cost and technical defaults : multi - path effect, reflect and scatter caused by cloud, smoke, water - dropping, the buildings, the grounds and its shape, the interference caus ed by the thunder, the complexity of device, difficult maintenance, and so on. now the band of the leakage coaxial line is up to 3ghz, leakage coaxial line has some advantages : good adaptability to cloud, smoke, water - dropping, the buildings, the grounds and its shapes, good steady field, it has some technical defaults : lower resolution for location and measuring velocity, the more complex of its sending - receiving relay devices, weak anti - interference, the strict demand for the hole size in the line, the cleaner work environment and the higher cost

    毫米波具有最大的帶寬和最高的通信速率，但也有最高的成本要求和較難克服的技術問題，即傳播的多徑效應，降水、雲霧、地形、地貌、建築物等的反射散射，打雷時的嚴重干擾，設備復雜，維護困難等等；泄漏同軸電纜的帶寬目前已做到3ghz ，具有對地形地貌建築物的適應性強，場強穩定，但它的定位測速精度低，它的收發中繼設備較復雜，抗干擾能力低，電纜上的開槽有著嚴格的尺寸要求，工作環境要求清潔，成本較高；傳統無線感應技術具有結構簡單，成本低廉，維護方便，定位精度較高的優點，但是，它沒有抗干擾能力。
