First, for a given integer value of the objective function, the lower and upper bounds of the variables were determined by the optimum simplex tableau of the linear programming relaxation problem. Then the conditions on the bounds were added to the constraints as cuts to the associated objective function hyperplane. Finally, a branch procedure of the branch-and-bound algorithm was applied to finding a feasible solution on the objective function hyperplane.

对于给定的目标函数整数值，首先利用线性规划松弛问题的最优单纯形表确定变量的上、下界，然后将变量的上、下界条件加入约束条件中对相应的目标函数超平面进行切割，最后应用分支定界算法中的分支方法来搜寻目标函数超平面上的可行解。

In chapter 2, we firstly introduce the model of a discrete-time neural network with generalized input-output function. The model generalizes the input-output function in transiently chaotic neural network to a class of continuous, differentiable and monotone increasing functions. Secondly we study the uniformly asymptotical stability of equilibrium in the non-autonomous model. Finally, several examples and numerical simulations are given to illustrate and reinforce our theories. In chapter 3, we firstly introduce a specific class of discrete-time neural network models with sinusoidal activation function.

在本文的第二章中，首先介绍了一类具有广义输入输出函数的非自治离散神经网络模型，该模型把瞬时混沌神经网络模型中的输入输出函数推广到了一般的单调递增且连续可微的函数；其次，利用Schauder不动点原理和利用Lyapunov函数逆定理依次证明了模型平衡点的存在性和该模型在时变权值下的一致渐近稳定性；最后，对几个具体的例子进行数值模拟，数值模拟的结果更好地说明了我们的结论。

With this method, we had several important differences compared to the YDmodel. First, the ratio of daily increment of PDT and the deficit of both water and nitrogen was used to estimate the effect of environment. Second, a nonlinear function was adopted to describe vernalization and thermal effectiveness (instead of three-stage linear function). Third, sinusoidal function was used to describe photoperiod curve cluster for different cultivars.

本模型在YDmodel基础上的改进主要有3点：（1）将每日生理发育时间的增量乘以水肥丰缺因子，改为除以水肥丰缺因子表现水肥对大麦发育的影响，客观体现了大麦在水肥丰缺条件下的发育延迟或提早现象；（2）将三段线性函数改为非线性函数表达春化效应和相对热效应，确立了不同品种相对春化效应和相对热效应的曲线族；（3）将线性函数改为正弦函数表达不同品种光周期效应。

As one of CC-Links features, RAS functions such as, stand-by master function, detaching slave station function and auto return function enable recovery from the communication fault and the system debug at start up time.

作为CC-Link的其中一种特性，RAS的特性，例如，补丁大师功能，分开的功能和自动回归功能能够使一开始错误的通信恢复。

Based on the theory of multi-aperture scintillation sensor,the contribution of aperture filter function and spectral response function to weighting function are discussed,respectively.

以多孔径闪烁方法的理论为基础，分别讨论了孔径滤波函数和光谱响应函数对权重函数的影响。

It can be shown that the base function for the optimal analysis of PSV data is HSV eigen-function deduced from the proper or thogonal decomposition of the geomagnetic model data instead of the lower degree spherical harmonic function in common use.

统计学意义上最优的分析方法不是直接对PSV数据作低阶轴对称球谐分析，而是通过对地磁场模型数据的特征正交分析，得到表征HSV的特征函数，再用它们去分析PSV形式的数据。

The serious degree that thinks function of kidney of can accurate report damages CysC reachs function of kidney spherule filtration, it is kidney function damages inchoate sensitive index, its sensitivity and particularity excel Scr, Ccr, and the operation goes handily, easily, but as determine of GFR sensitive inside content of source sex mark.

认为CysC能准确反映肾功能损害的严重程度及肾小球滤过功能，是肾功能损害早期的敏感指标，其敏感性和特异性优于Scr、Ccr，且操作简便、易行，可做为测定GFR的敏感内源性标志物。

In this system , travellers' applied function is to inquire about the information of the train and selling ticket ,the ticket agent of the net in system is to sells the ticket, the ticket agent of the station still have the function of returning the tickets besides selling the tickets, but administrator's applied function is to proceed the management with the train information, the ticket information and the ticket agent information.

旅客在该系统中所应用的功能是对列车和售票信息的查询。网点售票员在系统中所应用的主要功能是售票，车站售票员在系统中所应用的主要功能除了售票外还有退票，而系统的管理员所应用的功能则是对系统的列车信息，车票信息和售票员信息进行管理。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.
