确定因素

However, if coupled with some uncertainties, such as vacant houses in six months there is a certain proportion of investment buyers, as well as the pre-sale before the "pre" into account, then purchase the actual investment will exceed the proportion of the overall level of 16.6%.

但是，如果再加上一些不确定因素，如空置房屋在6个月内有一定比例的投资买家，以及预售前的"前"的帐户，然后购买将超过实际投资的比例整体水平的16.6 ％。

Uncertainties exist in either aleatory variability or epistemic uncertainty, but a weighted average of various alternatives in probabilistic seismic hazard analysis and the combination in methodology of PSHA and DSHA (deterministic seismic hazard analysis) should better prevent it from producing an extremely biased output of hazard estimates.

由于输入模型中不确定因素的存在，如输入参数的随机性和科学分析方法本身的不确定性，对分析结果的不确定性需审慎对待。通常对不同的模型或参量，包括地面衰减模型，进行加权平均可较为合理地减小结果的偏差。概率分析和确定性分析方法的结合亦为可取之有效途径。

In view of this, we impose a robust law in order to eliminate the influence of uncertain sources and approximation error.

有鉴於此，在控制法则中将引入强健控制的观念，企图涵盖所有不确定因素与杂讯源。

The second order asymptotic formulation for reliability analysis of parallel systems is employed in calculating the fatigue failure probability of the failure path of the system.

由于结构系统的疲劳破坏是一个受到大量不确定因素影响的现象，因此运用结构可靠性分析的基本理论和方法，对结构系统进行疲劳可靠性分析十分必要。

Simulation results are presented to illustrate that the method presented in the paper is feasible and asymptotic stability of the closed system is ensured.

仿真结果表明该方法是可行的，有效地防止了系统的颤振和不确定因素的影响。

This article reviewed the safety problems and uncertainties in the clinical application of probiotics, such as probiotics-induced infection and bacteremia, immunologic abnormalities and drug resistance.

本文就益生菌临床应用中的一些安全性问题和不确定因素，如益生菌引起的感染和菌血症、免疫异常、细菌耐药等作一综述。

Then combined with reliability computation,the stochastic finite element method is used to establish the relationship between the load effect and basic stochastic variable dealing with statistical features of variables.

可靠度分析是基于各种资料、数据的概率统计分析，在设计中用概率的方法定量地考虑了这些不确定因素，并用严格的概率来求得结构的可靠度指标。

Objective consideration of contemporary phenomena compels the conclusion that success or failure in competitive activities exhibits no tendency to be commensurate with innate capacity, but that a considerable element of the unpredictable must inevitably be taken into account.

对现实中诸多现象的客观观察使得我们不得不得出这样一个结论：竞争活动中的胜负并没有呈现出与人们内在能力的一致性。因此，我们不得不对相当大成分的不确定因素加以考虑。

Now America's commercial export control agency, the Bureau of Industry and Security, has proposed dramatic new export restrictions that alarm US industry, concern our trading allies and befuddle the Chinese by failing to address the stated threat and leaving significant uncertainties in their wake.

现在，美国的商业出口管理部门——商务部工业与安全局(Bureau of Industry and Security)，提议了全新的出口限制规定。这些规定并未应对所谓的威胁，而且留下大量不确定因素，因而让美国业界感到震惊，我们的贸易盟国感到忧虑，中国人感到迷惑。

He treads a well-practiced dance with every move recorded firmly -- and there can be no story if there is no choice, no chance, no uncertainty.

他娴熟地跳着一支舞蹈，舞蹈的所有步子早已记录确定，如果没有记录的选择，机遇，不确定因素，那么世界上就不存在什么故事。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
