本文採用全國首批建立的「縣級土地利用現狀數據庫」的基礎數據，結合影響土地利用變化的經濟、社會、環境等綜合因素，採用相關分析軟體（ dps 、 spss ）和數學分析方法（主成分分析、灰色關聯度分析、多元回歸分析、多元時空序列馬爾柯夫鏈分析、 gm （ 1 ， 1 ）預測模型分析、灰色序列gm （ 1 ， n ）模型分析等方法） ，對江安縣土地利用變化及其驅動力進行定性、定量研究，研究結果表明： 1江安縣人均總的土地資源數量和單一土地利用類型的數量在宜賓或四川省區域內均無優勢；地形對土地利用方式的選擇起著主導作用；土地利用變化的總趨勢是：耕地、林地、交通用地和水域面積不斷減少，居民點及工礦用地和未利用地面積不斷增加；景觀多樣性指數呈現「 」趨勢。As the decrease of the portion of the flexible resources ( mainly material resources ), the effectiveness of the traditional cost control ( tcc ) methods that mainly based on the thrift and restraint intention is decaying. therefore there is an imperative need for us to explore a new cost control theory appropriate to the new economic situation
隨著物質資源要素在經濟過程中投入總量、投入比重的逐漸減少或降低，以節約與守財意識為出發點的傳統成本控制方法的有效性正在不斷消失，這就要求我們聯系經濟過程的新環境，以成本形成過程高級化趨勢中的效用差異特徵為基礎，去探索成本控制的新理論。Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一，一方面風和潮汐通過激發內波，將能量向深海和大洋內區傳遞，另一方面，內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。This paper carries out a quantificational analysis upon the corpora of the english learners from primary schools to universities, especially middle schools, and makes comparisons in longitude and latitude. we find out from the comparisons that the language items puzzling the students most are : omission / addition of " ~ s " after third person singular verbs, omission / addition of " be ", error of tenses, error of articles, error of preposition collocations, agreement of subjects and verbs, error of singular / plural nouns, error of infinitives, error of part of speeches, error of possessive cases, empty of conjunctions in coordinative sentences, error of spellings ; elementary or intermediate learners ( such as freshmen ) suffer from native language transfer or simplification a lot ; advanced learners ( such as sophomores ) are affected by the overgeneralization of target language ; the error of part of speech or semantic selection ( except conceptual meaning ) runs through all phases, and it is likely to be fossilized
