冬汛 的英文怎麼說
中文拼音 [dōngxùn]-
Based on the simulation model theory of temperature and stress fields presented in this article, a large simulating program for high rccd has been developed, which can numerically simulate all kinds of temperature control measures, including water pipe cooling, heat insulating in winter, reducing place temperature of concrete, spraying water brume, and long interval over - watering surfaces overflowing in flood season.
基於本文提出的溫度場和徐變應力場模擬模型理論，編制了高碾壓混凝土壩的三維有限元模擬計算程序，在程序中考慮了各種溫控措施的數值模擬，包括：水管冷卻、冬季保溫、降低混凝土的澆築溫度、夏季混凝土表面噴水霧、施工汛期壩頂面過水等。( 4 ) there exist close relation between the floods season precipitation in northeast china and the anomalies of subtropical summer monsoon, the anomalies of cold air, sub - tropical anticyclone, polar front jet, north hemisphere general circulation anomalies in winter
（ 4 ）東北汛期降水與西南夏季風、北方冷空氣、副熱帶高壓、極鋒急流、前期冬季環流異常密切相關。Among them, working procedure optimization of construction of passing water gap in flood season in the same construction can be spread ; utilization of experience that lime dusts are mixed with macadam to satisfy winner construction, difficult problem of short construction stage in the cold area can be solved, this experience has the popular adaptability
其中度汛期過水缺口部位施工工序的優化在同類工程中具有推廣價值；利用碎石摻加石粉料滿足冬季施工的經驗解決了寒冷地區施工期短的難題，該經驗具有普遍的適應性。Because of the location and river characteristics, in winter, the ice flood is very serious and often cause ice flood disaster in inner mongolia reach of the yellow river, so it is one of the most important reaches of preventing ice flood
黃河上游內蒙古河段，由於其所處的地理位置及河道條件等因素，冬季冰情嚴重，經常產生凌汛災害，為黃河上重點防凌河段之一。On the basis of the analysis on the yangtze vole ' s disaster history and condition in dongting lake area, the influence of the lake beach ' s environmental evolution on the vole disaster is studicd in this paper. the rise of low - middle - level beach area causes the vole ' s population explosion, the reduction of high - level beach area forces the voles into the farmland during the flood season, and the emergence period ' s continual increase extends the vole ' s habitat areas and forces them to migrate into the farmland. the discarded dike provides a rest place halfway for the voles, which escape the flood, and the natural enemies of the voles, which are a natural barrier against the vole ' s population expansion, decreases. according to this study, the conclusions are put for ward as follows : after three - gorge project ' s construction it will produce great influences on the beach evolution in dongting lake area, leading to the changes of the vole ' s ecological environment situation and resulting in the vole ' s population changes which deserves attention
在分析洞庭湖區東方田鼠暴發成災史及災情的基礎上，研究了洞庭湖區洲灘演變對東方田鼠暴發成災的影響.研究認為，中低位洲灘出露面積不斷增大使東方田鼠種群迅速膨脹，高位洲灘出露面積減小造成汛期東方田鼠大量向垸內農田遷移;湖區洲灘冬春季連續出露天數增加延長了東方田鼠的繁殖期;汛期洪峰水位增高，洲灘大面積淹沒迫使東方田鼠大量遷向垸內;湖內廢棄湖堤為東方田鼠逃避洪水提供了中途休養之地;洲灘地抑制東方田鼠種群膨脹的天敵數量已大大減少.據此，本文指出，三峽工程建成后將對洞庭湖區洲灘演變產生重大影響，因而將改變東方田鼠種群生態環境條件，引起種群動態變化，值得注意According to plentiful of experimentation, some new build techniques are created, for example the technique of no watering fill in winter, the technique of prevent frostbite and crack of faceplate etc. these techniques were proved by the project of lianhua cfrd. at last this paper gives some conclusion
而且根據地區特點，進行了大量的實驗，給出了以往一般面板壩所未遇到過的施工工藝，如冬季堆石體不灑水填築、面板的防凍抗裂、壩體渡汛措施等以及採用新的爆破方法開採石料等新的施工工藝。The optimal design of the dam foundation in the river channel not only guarantees the construction of the foundation pit of the project but also saves a great amount of excavation quantities and concrete volume, which gains the obvious construction schedule benefit and economic benefit
1995年組織了冬季施工，通過引進設備，解決過渡料料源，加強施工力量，保持冬季施工大幹局面等措施，對實現1996年度汛工程形象面貌和年底第1臺機組發電起了積極促進作用。分享友人
