An inverse problem method is employed to determine the average magnitude of acid pollutants in groundwater in fengshui , zibo , shandong 摘要應(yīng)用反問題方法探討山東淄博市張店區(qū)灃水南部區(qū)域地下水中硫酸鹽的年入滲強(qiáng)度的數(shù)值反演問題。
Such methods are generally decreasing method , such as , feasible direction methods , constrained variable metric methods , etc . another class is sub - problems method , which approximates the optimal solution by solving a series of simple sub - problems , such as penalty function methods , trust region methods , and successive quadratic programming sub - problems , etc . the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point 另一類叫做子問題算法,這種算法是通過一系列簡單子問題的解來逼近原問題的最優(yōu)解,如罰函數(shù)法、信賴域算法、逐步二次規(guī)劃算法等。這兩類算法的一個共同特點是,通過比較當(dāng)前點和下一個迭代點的目標(biāo)函數(shù)值或評價函數(shù)值來確定迭代點的“優(yōu)”或“劣” ,若迭代點比當(dāng)前點“優(yōu)”則該迭代點可以被接受,否則須繼續(xù)搜索或調(diào)整子問題。
At present , the research on the retroactivity of criminal law , the field of domestic theory concentrating on more concretes problem in the administration of justice , judging the case as it stands , seldom probe into the criminal law value behind the retroactivity of criminal law , has made the trouble of attending trifles and neglecting essentials , and not solve the problem method from macroscopic 目前,國內(nèi)理論界在關(guān)于刑法的溯及力問題的研究中,多集中于司法中的具體問題,就事論事,很少探究溯及力問題背后的刑法價值取向,犯了舍本逐末的毛病,沒有從宏觀上探求解決溯及力問題的方法。
As studying the object - - urban space increase with to invite mechanism to have as the general objective law each other natural ecosystem , the analysis to it can be wide basically the clear inherent production and possibility evaded to the question ; and as studying the subject - - ecology lead and down function mechanism of urban planning just for solve above - mentioned problem key inherent law of power analyze safely , which have established the third part and solved the foundation that the problem method puts forward through the analysis to it 作為研究客體? ?城市空間增長與自然生態(tài)系統(tǒng)的互約機(jī)制是作為一般的客觀規(guī)律存在,對它的分析基本上可以廓清對于問題的內(nèi)在產(chǎn)生與規(guī)避的可能性;而作為研究主體? ?生態(tài)安全導(dǎo)向下城市規(guī)劃的作用機(jī)制正是對于解決上述問題核心動力的內(nèi)在規(guī)律分析,通過對它的分析奠定了第三部分解決問題方法提出的基礎(chǔ)。
