I will prove the existence of a solution of a class of probabilistic equations 中文摘要本研究是證明一個確率方程解的存在性。
With the temperature of sea area in situ , and the photoperiod during collecting samples , the two most important factors in inducing diapause , as the independent variable , whether the egg was in diapause ( or whether the female laid diapause eggs ) was regarded as the dependent variable , and the probabilistic equations of egg in diapause and female laying diapause eggs were established 以采集雌體時海區的現場溫度和日照時間這兩個影響滯育發生的最基本因素作為自變量,以卵滯育與否或雌體產滯育卵與否為因變量,建立了瘦尾胸刺水蚤卵滯育(或雌體產滯育卵)的概率預測模型。
Finally , this paper set up the substitute model between the new technology and the old one and studied characteristic of the diffusion system applied system dynamic method such as the stable points and phase portrait and hopf bifurcation and limit cycle of it . then studied the probability distribution function of them , and the probabilistic equation of this system 最后建立了四川大學碩士畢業論文創新技術和舊技術的技術更替模型,并運用系統動力學的方法分析了擴散系統在其不動點附近的變化特征和相圖以及改進系統的hopf分支、極限環等性質,討論了新舊技術的概率分布,并且將動力學方程轉化為概率方程進行分析。
