Through quantitative comparison of the salinity, temperature, wind, wave, current, tide, biogenesis elements, and rare elements of coral reef in the coral reef zone of the nansha islands in china with these in the open sea, it is found that the nutrients and primary productivity in the coral reef are several dozen or several hundred times higher than those in the open sea. it is indicated that, given sufficient sunlight, the coral reef eco - environment could provide very intense photosynthesis, thus pointing to the important reason why the coral reef zone is highly productive
根據中國南沙群島珊瑚礁區的溫度、鹽度、風、浪、流、潮、生源要素、稀有元素分析並與礁外海域定量比較,得出珊瑚礁區的營養物質和初級生產力比敞海高出幾十倍到幾百倍,表明只要有充足的陽光,珊瑚礁生態環境就可以提供十分強烈的光合作用,從而證明了珊瑚礁海區高生產力的重要原因。On base of the data analysis, three - dimensional tide - induced residual currents, the wind - driven and thermohaline currents in the bohai sea are diagnostically computed with an orthogonal curvilinear grid system, by means of a three - dimensional ecomsed model. the winter and summer thermohaline structure and circulation characteristics in bohai sea are analysed, and the circulation variance is discussed preliminarily. the tides and tidal currents in bohai sea are well reproduced

( 2 )通過對全新世渭河流域成壤環境演變問題的討論,揭示了全新世渭河流域土壤的發育具有階段性,表現為由溫濕的強成壤期向冷乾的沉積期(弱成壤期)演變、再向溫濕的強成壤期演變的規律;黃土一古土壤序列是不同生物氣候環境下、不同成壤過程發育的不同土壤類型演替而形成的復合型土壤剖面體系;而且由於冬夏季風環流及其環境效應在空間上的差異,使得復合型土壤剖面體系也存在著南北差異。Data used in this work are north pacific ssta, 160 stations precipitation of china, and ncep reanalysis data. main results are as follow : ( 1 ) it is found that a apparent transition of north pacific ssta in later 1970 ' s : eastern and middle - equatorial pacific ssta turns from cold to warm with area extending, and mid - latitude pacific ( west wind drift zone ) turns from warm to cold. during this transition of ssta, different characters also appear in el nino and la nina : before 1976, la nina happens more frequently, and its duration is longer, el nino zone develops from negative ssta in the early stage ; after 1976, el nino happens a little bit frequent and longer with more intensity than before, el nino zone develops from positive ssta in the early stage ; the course of ssta variation has an enso cycle of 2 - 6 years, annual oscillation of 8 - 9 years, and decadal variation of about 22 years
本文採用1950 - 1999年北太平洋海表溫度( sst ) 、中國160站夏季降水和ncep再分析的歐亞500hpa高度場等資料,利用eof 、 svd 、小波分析、合成分析和相關分析等方法,在分析北太平洋海溫時空分佈特徵的基礎上,著重探討了海溫異常及其年代際變化對我國東部降水的影響,並對降水、高度場和海溫三者之間的關系進行了分析,以試圖尋找三者異常之間可能的聯系,主要結論如下: ( 1 ) 1976年前後,北太平洋海溫經歷了一次明顯的轉變,赤道中、東太平洋厄爾尼諾海區由冷轉暖,暖水范圍增大,中緯度西風漂流區海溫由暖轉冷;在這樣的年代際背景下,厄爾尼諾、拉尼娜事件在不同的時期也有不同的特徵:在76年前,拉尼娜事件發生頻率高,持續時間長,事件起始於負海溫距平;而76年後,則是厄爾尼諾事件發生頻率略高,持續時間長,強度增大,事件起始於正海溫距平。The sst anomaly of the equatorial eastern pacific and west wind drift region both have influence on the general circulation and summer rainfall in north china, and the influence is nonlinear, which is not only manifested through the intensity change of anomaly of general circulation and summer rainfall in north china, but also through the spatial distribution pattern of the anomaly

在水利工程中經常需要採用數學模型模擬水流的流態,淺水方程是進行平面流態模擬計算的基本控制方程,但因其忽略了流速垂線分佈的不均勻性,在模擬某些平面流態(如風生流動、河灣水流、潛壩等工程附近的流動)時存在一定的局限性。The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th, june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa, subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average, this is the rainy season for the south of china, but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability, but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain

中尺度結構分析表明,本次暴雨具有明顯的中尺度特徵,是由三支氣流共同作用的結果,分析發現( 1 )地面東南風和地形在這次大暴雨過程起主要作用; ( 2 )東路冷空氣主要是通過中低層侵入陜南地區的,並與地面冷式錮囚鋒的形成密不可分; ( 3 )夜博士論文:中尺度地形對陜南暴雨的影響研究間垂直次級環流發展加強可能有兩個原因,一個是由於地形山谷風的作用,另一個是降水的潛熱釋放激發了上升運動: ( 4 )位勢不穩定層結的形成與低層暖濕平流的發展有很好的對應關系; ( 5 )本次暴雨的水汽主要靠偏南風急流將孟加拉灣和中國南海的水汽輸送至西北地區東部,為暴雨的發生提供了必要熱力條件。The results show that the weather process occurs because of typhoon trough with cold air, deep upper trough ; the southeast low - jet by typhoon transported large water vapour and great energy of instability to heavy rainfaill area ; cold air, lower convergence and upper divergence by deep upper trough lead to development of the east - ocean low pressure and occurd strong wind
分析結果表明:這次天氣過程是由臺風倒槽和冷空氣及深厚的高空槽共同作用引起的;臺風環流引起的東南低空急流為暴雨區輸送了大量的水汽和不穩定能量;冷空氣的侵入加上深厚的高空槽引起的低空輻合、中高層輻散,促使了東海低壓的劇烈發展,產生了猛烈的大風。Fi nite e1ement and finite difference are two primary methods used in the so1 ut ion process of di fferentia1 equat i on
水動力模型採用二維淺水風生流模型,有限元方法和有限差分方法是求解偏微分方程的兩種主要方法。Almost meanwhile, the north wind anomaly brings epwp warm water to equatorial vicinity by producing north ocean flow, which causes directly nino3 sst increase
幾乎與此同時,北風距平通過產生北風吹流將東太平洋暖池暖水由北向南輸送至赤道附近直接導致nino3區海表溫度增加。The edition of shiji ( historical records ) annotated by xuguang retains considerable literary materials of the variant editions of shiji popular among the six dynasties periods and pre - six - dynasties periods, which not only helps us very much to understand the original style of shiji its circulation and the reasons leading to the birth of variant editions, but also has an important values of reference for us to research into the errors of the present editions of shiji

對干位渦的分析表明:臺風或臺風環流區為高值位渦區,臺風越強,位渦中心值越大;對流層上部或平流層下部冷空氣(高位渦)的擴散南下與暖濕氣流的交匯是造成特大暴雨的重要原因,因為上游斜壓性的發展使對流層頂發生折疊,平流層與對流層相互作用增強,上下位渦區相接的形勢使低層渦旋發展,上升運動加強,位渦的下傳有效地降低了靜力穩定度,有利於位勢不穩定能量的釋放,使得暴雨增幅。The horizontal load actions of wind, wave, current and ice may cause the offshore platform sliding, and the platform sliding resistance includes soil cohesion, friction and soil resistance, so the bucket foundation platform should be designed to meet the requirements of stability against sliding to ensure the overall stability of platform

1951 1976 1977年,熱帶太平洋的walker環流和熱帶印度洋的緯向季風環流在海洋性大陸附近耦合,當elnino事件發生時,太平洋的西風異常可以通過這兩個緯向的垂直環流與印度洋的東風異常聯系起來,而1976 1977年以後,由於西太平洋walker環流上升支東移到澳大利亞北部,熱帶兩洋的緯向垂直環流無法耦合,熱帶太平洋elnino事件中的西風異常與熱帶印度洋的東風異常聯系減弱,所以1976 1977年以後, enso在熱帶印度洋的信號減弱了。Look also for signs of ongoing natural processes of air, earth, water, and life ( for example, light and wind ; water flow and erosion ; plant growth and animal movements )
