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(gè)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(shí)海區(qū)的現(xiàn)場(chǎng)溫度和日照時(shí)間這兩個(gè)影響滯育發(fā)生的最基本因素作為自變量,以卵滯育與否或雌體產(chǎn)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(chǎn)滯育卵)的概率預(yù)測(cè)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(xué)碩士畢業(yè)論文創(chuàng)新技術(shù)和舊技術(shù)的技術(shù)更替模型,并運(yùn)用系統(tǒng)動(dòng)力學(xué)的方法分析了擴(kuò)散系統(tǒng)在其不動(dòng)點(diǎn)附近的變化特征和相圖以及改進(jìn)系統(tǒng)的hopf分支、極限環(huán)等性質(zhì),討論了新舊技術(shù)的概率分布,并且將動(dòng)力學(xué)方程轉(zhuǎn)化為概率方程進(jìn)行分析。
