摘要受氣溫、日照、風(fēng)速、水汽壓等因子隨機(jī)變化的影響，參考作物騰發(fā)量時(shí)序過(guò)程具有非線性、多時(shí)間尺度變化等特性。 - aimed at tackling the stochastic variations caused by non-artificial natural factors and accidental factors such as nonpoint source contamination and point source contamination in geochemical maps for different continental and sea media of eastern zhejiang coastal area, this paper puts forward a geochemical map formation method for different continental and sea media based on a suitable data-processing model and color area spatial distribution so as to improve the map face effects
摘要針對(duì)浙東沿海地區(qū)陸海不同介質(zhì)采樣區(qū)地球化學(xué)圖中出現(xiàn)的自然因素，以及非點(diǎn)源污染和點(diǎn)源污染等因素引起的隨機(jī)變異，提出選擇一種適宜的數(shù)據(jù)處理模型和色區(qū)空間分配為內(nèi)容的陸海不同介質(zhì)地球化學(xué)成圖方法，以改善圖面效果。 - considering the fuzziness of some boundary conditions enviroment media, and especially some loads in the engineering structure analysis, we go further into the computation based on the dynamic problem of fuzzy finite element ( ffe ), study further and systematically the analysis and solution . the principle of fuzzy minimum potential energy is established, and the balance equation of fuzzy finite element is reasoned by making fuzzy variation . at the same time, the dynamic balance equation of stochastic by making stochastic variation ， also the fuzzy stochastic dynamic balance equation is deduced . based the theory that the degree of the fuzziness and probability can be measured, in the other word, by using the concept of fuzzy entropy and entropy, pure fuzzy dynamic structure is given through transforming the probability to fuzziness . for the fuzzy parameter can be regarded as a fuzzy vector with dimensions, the structure's eigenvalue, by the theory of small parameter
建立了模糊瞬時(shí)最小勢(shì)能原理，運(yùn)用模糊變分原理導(dǎo)出了模糊有限元?jiǎng)恿ζ胶夥匠?；同時(shí)，利用隨機(jī)變分原理導(dǎo)出了動(dòng)力問(wèn)題的隨機(jī)有限元方程，同時(shí)得到了模糊隨機(jī)動(dòng)力問(wèn)題的有限元平衡方程。根據(jù)模糊度和概率度可以度量的原理，即利用模糊熵和概率熵的概念，把結(jié)構(gòu)的隨機(jī)性等效地轉(zhuǎn)化為結(jié)構(gòu)的模糊性，得到純粹模糊性的動(dòng)力結(jié)構(gòu)。把結(jié)構(gòu)所具有的模糊參數(shù)看作一個(gè)維的模糊向量，利用小參數(shù)攝動(dòng)原理，把結(jié)構(gòu)的特征值，特征向量和位移都在模糊向量的均值處進(jìn)行泰勒展開，得到一組遞歸方程，即可以求得結(jié)構(gòu)的模糊特征值，特征向量和模糊位移。 - It's difficult to find stochastic variation in a sentence. 用stochastic variation造句挺難的
