bound variable 中文意思是什麼
bound variable
解釋
有界變量-
In lazy evaluation, an expression is not evaluated as soon as it is bound to a variable, but when the evaluator is forced to produce the expression s value
在懶惰計算中，表達式不是在綁定到變量時立即計算，而是在求值程序需要產生表達式的值時進行計算。 -
The conventional variable structure control technique for uncertain system requires that the uncertainty bound is known as a premise to assure robustness. the requirement creates an over - conservative controller and enlarges chattering. the proposed controller regards the influence of unknown disturbances and parameter uncertainties as an equivalent disturbance and generates an on - line estimation used in smc to cancel the slowly varying uncertainties by the mechanism of time delay. the reaching law approach is used to get the conditions and band of quasi - sliding mode. the new methodology offers a robust feedback control with much lower gains and reduces chattering without a prior knowledge of the uncertainty bounds or matched conditions
常規變結構控制用於不確定系統，須利用不確定性界確保系統的魯棒性，控制器過于保守且抖振變大.本文把未知干擾和參數不確定性的影響等效為名義系統的外界干擾，利用時延技術對干擾進行在線估計，並將估計值引入到變結構控制中，從而抵消掉系統中的慢變不確定性，利用離散趨近律法，推出了準滑動模態的存在條件及其帶寬.該方法克服了以往控制方法中須已知不確定性界的限制，且不必滿足匹配條件，用較低的控制增益保證了系統的魯棒性，降低了準滑動模態帶即削弱了抖振 -

Because structures are value types, each structure variable is permanently bound to an individual structure instance
由於結構是值類型，每個結構變量都永久地綁定到一個單獨的結構實例。 -
Also bound. the highest numbered or lowest numbered address of a particular area of storage, partition, array, or variable
也稱為邊界，特定存儲區域、分區或變量的最高和最低編號地址。 -
Finally, degree reduction of interval rational triangular b - b surfaces is discussed. the problem is also converted to degree reduction of bi - variable polynomials with upper bound. according to degenerating conditions of triangular b - b surfaces, an optimization model is constructed and optimal solutions under certain constrains are calculated
先將該問題轉化為雙變量多項式的限制上界的降階問題，然後採用最優化方法，結合三角b - b曲面的退化條件，建立約束優化模型，求出約束意義下的最優解。 -
It is observed experimentally and algorithmically that when training data are noisy and overlapping, many support vectors have lagrange multipliers on the upper bound. if it were known beforehand which examples are bound support vectors, these examples could be removed from the training set and their values are fixed at the upper bound. due to the reduced free variable counts, this method is promising to improve training time
實驗和演算法推導顯示在強噪聲和類間重疊數據下訓練svm得到的支持向量很多處于邊界位置，如果我們能夠預先知道哪些樣本是邊界支持向量，這些邊界支持向量的值就可以被固定在邊界處，從而不參加訓練過程，這樣，訓練過程中要優化的變量就可以減少，運行時間也可以縮短。 -
Variables can only be bound once ! the value of a variable can never be changed once it has been set ( bound )
變量只能被綁定一次，一旦綁定完成後，不允許修改原綁定關系。 -
First, since this is the scheme language, the types are bound to the values themselves, not the variable names, so there is no worry at all about the variable type problems that occurred in the c version
首先，由於這個宏採用的是scheme語言，因此類型都已經被綁定到值本身上面了，而不是綁定到變量名上面，因此根本不用擔心會出現c版本中那種變量類型的問題。 -
The method to control chaos by using uniform phase space compression is applied to economic systems in this paper, and a new stabilization method celled threshold stabilization method that suppresses chaos by adding upper hound or and lower bound to state variable is developed according to the characteristic of economic systems
摘要把利用相空間壓縮來控制混沌應用於經濟系統， ?針對經濟系統的特點引申出閾值控製法，即通過限制變量取值的上限或（和）下限來達到控制混沌的目的。 -
Due to varying radio channel, the admission bound is variable rather than a fixed boundary. the probability distribution of under imperfect control for multiple service is deduced
根據無線通道的變動特性，接入準則的限更適合採用可變的限而不是一個固定的限。 -
Attribute, then the named variable will be bound to successive elements of the collection for each iteration pass
屬性指定的，那麼對于每次迭代該已命名變量都將被綁定到集合后續元素上。 -
