The result shows that : the sand - dust storm occured in favorable climate background that is drought and rainless, the tilted trough and mongolia cyclone are the important weather systems that caused the severe sand - dust storm, tilted trough and strong frontal zone caused the mongolia cyclone developed and the clod front strengthened at surface, high jet and ferrel circulation are the main reason that momentum spreaded downward from higher level and frontal zone strengthened on lower level
結果表明:沙塵暴是在乾旱少雨的有利的氣候背景下產生的。斜壓槽和蒙古氣旋是觸發這次強沙塵暴天氣過程的重要的天氣系統,高空斜壓槽和強鋒區促使了地面蒙古氣旋的發展和冷鋒的加強,誘發沙塵暴天氣。高空急流及其下方的ferrel環流起到了高層動量下傳和加強低層鋒區的重要作用。We can use the mm5 model in definite time, definite area weather forecasting. we conclude that : : the moving route of this necw in its developing progress was direct - south along latitude, the cold air is rough, and just this made the rough vertical velocity ; the necw southern moving and conflicting with the west pacification sub - tropical high makes rough jet steam. the plenty south - west warm and wet air made by the jet stream gave the rainstorm demanded vapor ;. the rough vertical velocity by jet stream is a main reason in this rainstorm ; the mm5 model uses four - direction analysis data as its input, this avoids some errors occurred in observe and transfer, thus made the result more useful

由於南方地區灌區面積大,管灌系統規模大,與其相配套的大口徑管材、管件規格少,配套建築物較多,灌區類型多樣,壓力變化范圍大,技術難度高,基層工程技術人員了解和掌握不充分,至今尚無適合南方地區低壓管道輸水灌溉工程設計的規范,這些是影響南方低壓管道輸水灌溉技術發展的因素。( 2 ) because of t he variability of rock subjected to outside action, three new conceptions : postive damage basic damage and negative damage, are suggested, which can deal with the condition that rock density became large. ( 3 ) the present damage variables based on ct number mostly include ct average number of the rock without damage, which is difficult to measure, so a new damage variable, which includes the average ct number is proposed, on the other hand, strain equal theory is generalized because the one put foreword by lemaitre is not good enough to use. ( 4 ) a axial damage constitutive equation is proposed and testified. ( 5 ) with the circle times, the damage propagation laws of two different rocks, subjected to circle of freezing and thawing, are studied, and in the analysis process, traditional analysis method including average ct number and is used, some important conclusions are reached : inner damage of soft rock containing a large mount of apertures is largely propagating with the time increasement of circle, however, at the preliminary time, the hard rock containing a small mount of aperture is a little propagating, at late time, the influence become large ; ( 6 ) zone separation and statistics frequency put forward is used to analysized the three different damage propagation in the open circumstance, when they are subjected to the different circle times of freezing and thawing, in which the temperature variability is linear, different freezing rate, and different freezing temperature, and no water is supplied during the test
在研究過程中本文主要做了以下工作: ( 1 )針對巖石損傷變化較小時,運用ct均值和方差分析不方便的缺陷,本文提出運用對ct數范圍劃分區段的方法,根據各區段統計頻率的變化規律來分析損傷擴展狀況; ( 2 )針對巖石受到外部作用的多變性,本文提出了基準損傷,正損傷,負損傷的概念,在某種程度上考慮了巖石受到外部作用時的壓密情況; ( 3 )現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值,這實際上是很難觀測到的,因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量,由於現有的勒邁特教授應變等價原理使用上的不便,本文在其基礎上進行了推廣; ( 4 )建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程,並用算例進行了驗證; ( 5 )對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時,內部損傷隨凍融循環次數增加的擴展規律進行了探討,主要運用了常規的ct均值和ct方差的分析方法進行分析,試驗發現:對于孔隙率和含水率較高,密度和強度較低的軟弱巖石,凍融循環次數對損傷結構的擴展有明顯的影響,而對于孔隙率和含水率較低,密度和強度較高的硬巖,凍融循環次數對其損傷結構擴展初期由於含水率低的原因,影響不是太大,而後期由於水補給后,含水率較高的原因,凍融影響逐漸增大; ( 6 )運用了本文提出的區段劃分和統計頻率的方法,深入地分析了開放環境下的線性溫度變化的凍融循環次數,凍結溫度,凍結速度不同巖石作用時,其內部損傷隨凍融循環次數,凍結速度和凍結溫度變化的擴展規律,需要指出的是除了在試驗前飽水外,凍融過程中沒有補水。When most people think of a grid, the idea of an interconnected system for the distribution of electricity or electromagnetic signals over a wide area, especially a network of high - tension cables and power stations, comes to mind
