洪積統 的英文怎麼說
中文拼音 [hóngjītǒng]
洪積統
英文
diluvion-
When catchment area, average channel gradient and catchment shape factor of designed culvert or bridge are known, a user can be convenient to get local parameters c, e and b from standard contour charts and easy to calculate flood flow just by a calculator. design period of flood flow is enormously shortened as well as a high precision. estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods, so that much cost is cut down a s reducing the span of culvert or small bridge
以75000km ~ 2的川中丘陵地區為試點研究區，繪制了該地區新模型的參數等值線圖，率定了不同設計頻率的改正系數，使設計者只需在地形圖上獲取集水面積，河道平均坡降和流域形狀系數，在參數等值線圖上查得橋涵所在地的相應參數，使用計算器即可迅速計算出設計流量，大大縮短了設計周期，且精度較高，設計的洪水流量一般低於傳統方法，從而可減小橋涵跨徑，節省投資。Ketter r. l. and prawel s. p. jr., modern methods of engineering computation, mcgraw - hill, inc., new york, ny. ( 1996 )
洪文政，建築物加速度訊號即時積分系統軟硬體整合應用研究，碩士論文，國立成功大學土木工程研究所，臺南（ 2006 ） 。The system possesses the real time correcting function, which can avoid error accumulation and highly increase the forecasting accuracy ; ( 3 ) the flood control system can be multiple - scheme designed, that is, the control schemes can be designed in terms of different control ways for hydro - projects. simulated computation can be carried out to obtain multiple schemes that can be used by the leaders for decision making after risk and consequences estimation, so as to scientifically enhance th
系統具有實時校正功能，可以避免誤差累積，極大地提高了預報精度; （ 3 ）防洪調度系統可以進行多方案設計，即可以根據水工建築物不同的調度方式來設計調度方案，並進行模擬調度計算，最終生成多個方案，供領導決策，提高了防洪決策的科學性; （ 4 ）系統採用的數據均建立在實時雨情、水情、工情和天氣預報等數據庫基礎上，預報、調度均能做到快速及時。By using gis, " the flood prevention information system of daqing oil field " played an important role in the management of drainage in daqing oil field
「大慶油田防汛信息服務系統」將地理信息系統應用於大慶油田的排水管理當中，使其在大慶油田的排水防洪工作中發揮積極作用。Measures were taken in structure designing to enlarge the discharging capacity of the spillway. in non - structure designing, the telemetric system was designed for forecasting the runoff and flood by monitoring the rainfall and water level of river station, and a warning system was designed to avoid downstream people from the dangerous situation of man - made flood
通過劃分取水口上游淤積、取水口淤積和流態、過機泥沙三個子系統，對三個方案的二維計算結果採用模糊集理論優化分析，結論是155方案，即洪水來臨時把庫水位降到64米方案為最優方案。The remote sensing imagery change detection can be categorized into three classes according to the aims of the processing : the change detection of the specific targets, such as changes of the airports, the bridges, the harbors, the missile bases etc. ; the change detection of the linear shape targets, such as changes of the roads, the airports, the buildings and the other linear targets whose outlines can be described by some lines ; the change detection of large area targets, such as the changes of the cover of some region, the development of the cities, the disaster evaluation of the floods and so on
遙感圖像變化檢測方法（簡稱變化檢測）根據處理目標要求可以分為三類：特定類目標的變化檢測，如機場、橋梁、港口、導彈基地等目標的變化檢測；線性體目標的變化檢測，如道路、機場、橋梁和一般建築物等目標的變化檢測；大面積目標的變化檢測，如某地域的植被變化、城市的發展、洪水災害評估等。本文系統地研究了基於模式識別知識檢測特定類目標、線性體目標和大面積目標變化的變化檢測方法。分享友人
