不确定

There are more uncertain and volatile factors in the international economic climate," he said."

他表示：世界经济增长明显放缓，在国际经济环境中存在很多不确定和不稳定因素。

To illustrate, the XYZ insurance company might have last year bought a policy obligating us to pay the first $1 billion of losses and loss adjustment expenses from events that happened in, say, 1995 and earlier years.

另外还有一个影响更大的因素，也是你在别的地方找不到的，那就是有些公司想要把过去发生但却不确定的损失解决掉，简单的说，有家 XYZ 保险公司在去年向我们买了一张保单，约定我们必须支付头 10 亿美元的损失再加上以前年度，比如说 1995 年后续的损失调整费用，这些合约的金额有可能相当大，当然不论如何，我们还是会定一个上限，我们在 2000 年签了几件这类的合约，到了 2001 年也会再签下几件。

We are unsure whether it means for free on the day of release, or is purporting to give it to you early (it says you'll have it "first"): either way don't do it.

我们不确定它的意思是否会给你免费的，或者声称提前给你：任意一种都不可能。

But due to the existence of some uncertain factors, such as asymmetric information, the conflict can be engendered between the members, even led to the relation rupturing.

但是存在由于信息不对称等的不确定因素，各成员间会产生冲突甚至导致关系的破裂。

First, a reealuation of published epidemiologic studies of consumption of sweetened beerages and oerweight shows that most such studies either are cross-sectional or are based on passie sureillance of temporal trends and thus permit no conclusions about causal links. Second, research eidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusie.

首先，加糖饮料的消费与肥胖症之间流行病学的研究的重新评估表明：大部分如此的研究要么是片面的，要么是消极的暂时的趋势考察，因此不能得出两者之间因果关系的结论；其次，拿短期的对不同的固体能量和液体能量的满意程度做比较的研究证据也是不确定的。

I'm not certain I found what I was looking for, but I think I found spells that were useful.

&&我不确定我是不是发现了我在找的东西，但是我觉得我找到了很有用的咒语。

In rich countries the prospect of the general population succumbing to AIDS is now almost nil.

这句我也不确定我翻的就对，但是我觉得你的译文也不太到位。

Because it is only being deployed within his own body and never superimposes over the external space, it is capable of avoiding the corrective impulse by the world and can be sustained almost indefinitely as long as he possesses enough energy.

因为这是唯一在他体内展开又不会加到外部空间的方法，这是一种避免世界修正的能力和能被持久的几乎不确定的时间（至少到他拥有足够的能量为止）。

Three kinds of arm's robust control theorys are designed: the torque control based on FNN controller, the computed torque control with sliding mode compensation and the computed torque control with WNN compensation. FNN syncretizes the reasoning ability of fuzzy control and parameters' self-learning ability of neural networks. It does not depend on the precision of the mathematical model, and can overcome the impact of the uncertainty effectively. So FNN is regarded as the manipulator controller and used to the trajectory tracking of arm control. The computed torque control with sliding mode compensation is designed.

在此基础上，研究了机械手臂的鲁棒控制法，分别设计了基于模糊神经网络的机械手臂力矩控制方法、基于滑模变结构控制补偿的机械手臂力矩控制方法以及基于小波神经网络补偿的机械手臂力矩控制方法，具体内容如下：模糊神经网络融合了模糊控制的推理能力和神经网络的参数自学习能力，它不依赖于对象精确的数学模型，能有效地克服被控对象存在的不确定部分的影响，本文把模糊神经网络作为机械手臂的关节伺服控制器，通过对网络参数的学习训练来调整机械手臂关节的控制力矩，实现对机械手臂的轨迹跟踪控制。

The primary factors influencing the concentration of sodium hydroxide titrating solution were confirmed.

笔者对1mol/L NaOH溶液标定过程中的测量不确定度进行了分析和评定，对同种类型实验进行不

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
