不能确定的

Federal Electoral Institute experts say the vote count was so close that they could not determine a winner through a random sample quick count.

To be fair, economists can't be expected to predict the future with any kind of exactitude.

公平地说，我们不能期待经济学家们对未来做出什么确定的预测。

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。

Some aggregation methods either work off-line or are unable to confirm parameters while working on-line, let alone effective real-time alert.

一些聚合方法要么离线作用，要么在线却难以确定诸多参数更不能实现有效的实时预警。

Where by reason of the provisions of paragraph 1 a company is a resident of both Contracting States, then the competent authorities of the Contracting States shall determine through consultations the Contracting State of which the company shall be deemed to be a resident for the purposes of this Agreement, and, if they are unable to so determine, the company shall not be considered to be a resident of either Contracting State for purposes of enjoying benefits under this Agreement.

With the structure of FNN turning more complex, the good approach or classification is hard to get because of redundancies and uncertainties caused by both large volume uncertain data and lack of prior knowledge. Based on high order spectral reduction for rulers, a new structure changed Fuzzy Neural Network is proposed.

针对先验知识不完备和不确定的情况下海量数据造成的冗余和互斥，模糊神经网络结构变得复杂化并不能很快逼近和分类输出对象的情况，提出了一种基于高阶谱完成规则约简的变结构模糊神经网络的模型。

The demand of order is changeable and uncertain in teal environment.

在实际环境中，各节点的需求是不断变化的，将这种变化的不确定的需求转化为静态需求为企业运作提供了便利，但却不能在时间上赢得竞争优势。

The ASRM's Tipton argues that it's difficult to determine whether doctors fail in their responsibility to communicate the risks or whether patients simply do not absorb all the necessary information before signing consent documents.

美国生殖医学学会的蒂普敦认为，人们很难确定的是，在签署同意文件之前，是医生不能尽责地就捐卵的风险与病人沟通，还是患者根本听不进所有必要的信息。

Especially, contact angle of a real three-phase system is usually not, as predicted by the Young equation, defined uniquely, but varies in a range of values-the phenomenon known as hysteresis of the contact angle.

特别是，实际三相系统的接触角一般能在某个范围内被钉扎不动，不象Young方程所指出的那样有唯一确定的值，称之为接触角的滞后现象。
