Suppressing the interference is an important issue in OFDMA multi-cellular systems because the interference spreading function is only suitable for code division multiple access systems but not for OFDMA systems.

能有效抑制干扰的影响是蜂巢式网路系统的重要问题，因为干扰扩展函数只能适用在分码多工系统而无法适用於正交分频多工系统。

For example, provide graphs showing payloads/sec as a function of timeout interval, for various error rates.

比如，为错误率提供图形显示的每秒的有效载荷作为时间延迟的一个函数。

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。

This function registers a handler, first making sure that the requested interrupt is a valid one, and that it is not already allocated to another device unless both devices understand shared IRQs (see the later section "Interrupt sharing").

这个函数注册一个句柄，首先确保请求的中断是一个有效的中断号，而且它还没有分配给另一个设备，除非两个设备都明确的使用共享IRQ(参见后面的一节"Interrupt sharing")。

Thus,the principle and methods for widening the ranges oftime and space for applying water production function of rice and principle and methods fordrawing the isogram of WSI based on the isogram of ET0 and the soil map have beenestablished.

通过参照作物需水量及其频率以及不同地区土壤有效含水量为媒介，建立了对水分敏感指标在不同水文年份和不同地区进行预报的数学模型，据此提出了水稻水分生产函数在时、空两方面插补、延长、移用与扩展的理论与方法。

Iterated function system is an effective method to define and describe fractals. An IFS determines only one fractal which is called attractor.

迭代函数系统是定义和描绘分形的有效方法，每个 IFS确定了唯一一个称为吸引子的分形。

Based on a relationship between the RF and Jacobi matrix, a novel method which is independent of the forward modeling for a fast algorithm of Jacobi matrix employing the RF was advanced.

通过建立二维非均质反演Jacobi矩阵与响应函数的关系，开辟了Jacobi矩阵快速算法构造的有效途径。
