constraint n. 1.強迫,拘束。 2.約束,壓抑,拘泥。 3.強制力。 4.緊張感[狀態(tài)]。 by constraint 勉強,強迫。 feel constraint覺得局促不安,感受壓迫。 show constraint顯得局促。 under [in] constraint 被迫,不得不;被束縛著。
degree n. 1.程度;等級。 2.階層,地位。 3.學位,學術。 4.度,度數。 5.【數學】次;冪。 6.【音樂】階,度,音程。 7.【語法】(形容詞和副詞的)級。 8.【法律】親等。 He was tired to such a degree that he fainted. 他疲乏得昏了過去。 people of every degree 各階層的人們。 a man of high degree 地位高的人們。 give [take] a degree 授與[取得]學位。 the prohibited degrees (of marriage) 禁止結婚的親等 〔一、二、三等親〕。 third degree 〔美國〕(警察的)嚴厲的拷問。 by degrees 漸次,漸漸,逐漸。 by slow degrees 慢慢,一點兒一點兒地。 degree of frost 零下(10 degrees of frost 零下10度)。 in a degree 有一點兒。 in its degree 各有(所長等)(Each is useful in its degree. 各有不同程度的用處)。 in some degree 多少。 to a certain degree 相當。 to a degree 非常;〔美國〕有點。 to the last degree 極端,再…沒有了。
A new concept of so - called " constraint degree " is introduced for a multi - objective programming problems , on the basis of which the compatibility of the programming problems is described by all sequences of the constraint degree 摘要對于多目標規(guī)劃問題,提出了約束度的概念,基于此概念利用各個約束度序列可以刻劃該規(guī)劃系統的相容性。
In chapter 2 , by defining some concepts , such as constraint unit , constraint aggregate , constraint relation , constraint method , constraint chain , constraint degree and associate constraint sub _ aggregate etc . the basic constraint factors that affect the complex pipeline system packing are fully analyzed in the first . in the following , a mathematical modelling method used for complex pipeline system " optimization packing design is brought forth based on the optimization target decomposing , then a mode of generalized proposal field of the complex pipeline system packing design is constructed . finally , a variant genetic algorithm for the solution of the mode mentioned above is derived 第二章,通過定義約束元、約束集、約束關系、約束方法、約束鏈、約束度、關聯約束子集等概念,對影響復雜管線系統規(guī)劃布置的基本約束因素進行了較為全面、系統的分析;探討了基于目標分解的復雜管線系統優(yōu)化布置問題的數學描述方法,建立了面向復雜管線系統布置的廣義布置方案場模型,并在此基礎上設計了求解該模型的變異遺傳算法。
The notion of explicitly geometric shape feature position of primitive is introduced , and the classification of explicitly geometric shape feature position is studied carefully . secondly , taken the combining principle of combined entity as the basis , the notion of explicitly geometric shape feature position constraint of combined entity is introduced . the classification - the explicitly reductive capacity to location dimension , constraint degree , dividing constraint level of explicitly geometric shape feature position constraint are systematically studied 其次,對組合體的組合機理進行了分析,并在此基礎上,引入了組合體的隱式幾何形狀特征位的概念,系統的討論了組合體的隱式幾何形狀特征位約束的分類、組合體的隱式幾何形狀特征位約束對定位尺寸隱含性縮減的性質、組合體的隱式幾何形狀特征位約束的約束度、隱式幾何形狀特征位約束的優(yōu)先級別劃分。
