不确定性

A neural-network-based robust compensating control method is proposed for the robots with constructed and unconstructed uncertainty The robust controller consists of a computed torque controller and add-on compensating controller The effective way using neural network to estimate the system uncertainty is also given.

四、对具有结构型和非结构型不确定性的机器人提出了一种基于神经网络补偿的鲁棒控制方法，控制器由一个计算力矩控制器和一个可切入的神经网络补偿控制器组成，给出一种利用神经网络学习机器人不确定性的有效途径。

The traders\' anticipation of is the directly reason for uncertainty of exchange forecast, circumstances and unicycle of the market.

交易者心理预期的变化是造成汇率预测的不确定性、环境变化影响的不确定性和市场轨迹的非周期性循环等复杂性特征的主要原因。

Because of the strong non-linearity of the systems themselves and the addition of the resonant components, the modeling of these system becomes difficult, its effect sometimes is unideal even invalid that applying conventional controlling methods. The strategy of fuzzy control needn't constituting mathematics model and control the system based on control experience completely, fuzzy control is fit for controlling the systems of non-linear and uncertain.

但是由于这些系统本身严重的非线性、时变不确定性以及谐振元件的加入，使得系统数学模型很难建立，应用传统的控制方法有时效果不理想甚至是无效的，而模糊控制策略无需建立精确数学模型，是在控制经验基础上实现对系统进行控制，适合对非线性及不确定性系统进行有效控制。

This article classifies the uncertainty as essential one and uninformative one in term of its origin. The latter results from incomplete information and need more attention from economics.

本文根据来源将其分为本质上的不确定性和无知的不确定性，后者根源于信息不足，具有研究的必要性。

Since many of these uncertainties are unknown, unquantifiable or their laws of variation are not yet known. What's more, man has to make decisions under these imperfect conditions, therefore all these uncertainties are included in the randomness and dealt with probability methods.

但由于这些不确定性有许多是未知的、无法量化的或变化规律不清楚的，而人们又必须在这些不完善的条件下进行决策和设计，因此就把所有这些不确定性都归结为随机性，利用概率统计方法加以研究。

Part Ⅰ: Since the study about breaking onset criteria base on the downward acceleration or on the wave slope shows great discrepancy, the models that estimating breaking probability and whitecap coverage according to these two criteria are problematic.

第一部分：因所采用的动力学或波陡判据的不确定性和海浪谱四阶矩的难以确定，现已提出的关于风浪破碎率和白浪覆盖率的统计模式有一定的不确定性。

The law does not concentrate on individual risk, which results from price fluctuation, but on negative uncertainty of market system, which results from inperfect futures market distemperedness, namely futures risk is negative uncertainty resulting from inperfect futures market.

法律所关注的风险不在于价格波动导致的单个市场主体损失，而在于因期货市场不健全导致的市场整体的负的不确定性，即期货风险是由于期货市场不健全导致的负的不确定性。

Real options can evaluate exactly the value of investments through reflecting the flexibleness, uncertainty and irreversibility.

在不确定性投资中，实物期权评价方法充分考虑了项目投资中的管理灵活性、不确定性和不可逆性，因而更能准确地评估项目投资的价值。

Compared with the objects protected by the traditional intellectual property law, the folklore displays the indefinitiveness of the object itself and value realization in time.

与传统知识产权所保护的客体相比，民间文学艺术却表现出自身对象的不确定性和资源价值实现预期在时间上的不确定性，正因为如此，对民间文学艺术的&人人得自由使用&便成为值得怀疑的并有理由加以改变的事实，用传统的知识产权制度对folklore加以保护显然不合时宜，必须创建一种全新的制度，作为知识产权保护制度体系中的一个分支，以满足民间文学艺术的特殊要求。

Despite the fact that deterministic relationships are used in most compiterized models for engineering,the model outputs are indeterministic due to the uncertain and stochastic nature of the model inputs and parameters. All the uncertainty may contribute to the stochsticity of the input parameters of a corresponding model which, in turn, result in output uncertainty.

尽管大部份工程应用电脑模式均以定率式的物理关系作为基础，但引用电脑模式进行设计，必须考虑隐含在模式输入与控制参数的不确定性，及其所产生模式输出的不确定性。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
