查询词典 function variable

Aim at ubiquitous parallel multi-reservoir structure in our countrys basin, the universal objective function including coefficient Bi embodying a spatial significance difference at different flood control points and variable ai denoting a selection of scheduling mode is established, which provide a valid intervenor interface for flood control consultation decision. According to the real-time requirement, a model of reservoir storage allocation is proposed, which embody basic idea of phasic compensation. Passing the dynamic correction to cut down the disadvantageous influence that indetermination result in on the certain degree, joining together the step alternation solving method, this model can maximally consider bias of decision makers, ensure the rationality and practicability of the solutions.

针对我国流域中普遍存在的并联库群结构，论文提出包含不同防洪点重要性的系数β_i和选择调度模式的变量α_i的通用目标函数，为防洪会商决策，提供了有效的人工干预接口，根据实时性要求提出动态分配防洪库容的库容分配方法，体现了相机补偿的基本思想，通过动态修正在一定程度上可以削减不确定性造成的不利影响，结合分步迭代求解技术，能最大限度体现决策者的偏好，保障解的合理性和可操作性。

Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.

摘 要：应用混沌理论，分析了网络流量，用单变量的网络流量时间序列重构与网络动力系统等距同构的相空间，进而计算了实际网络的关维数和Lyapunov指数，并证实了网络流量存在混沌特性；据此建立了基于径向基函数神经网络的模型，并对实际网络数据流进行了预测。

In physical chemistry, indeterminate parameters in dependent variable and function can be ascertained by resolving linear simultaneous equations group.

在物理化学中，多数情况下，两个物理量之间的函数并非简单的直线关系，有可能因变量与函数式中各待定参数之间是线性关系。

But what if the variable is local to the parent function?

但是如果变量是父函数的局部变量又会怎么样呢？
