| 5. | The contamination degree is contamination level to be controlled and change the oil when system is dynamic balance 提出了液压润滑系统污染动态平衡时的污染度亦即为液压润滑系统需要控制的目标污染度,并以该目标污染度作为换油指标。 |
| 6. | Sediment contamination levels in the victoria harbour wcz have always been a problem , apparently building up over time as a result of discharges from a number of industries between the 1960s and the 1980s 维多利亚港的沉积物污染问题,主要是六十至八十年代的工厂污水排放所致。 |
| 7. | This novel transport agent ( nh4 ) 3zncl5 possesses more advantages than lz , such as the higher thermostability , relatively lower pressure at room temperature , lower contamination level to znse crystals 该输运剂具有比传统输运剂i _ 2更好的综合优势,例如其具有热稳定性好、室温下蒸汽压低、对晶体污染小、有利于生长富zn单晶和操作简便等。 |
| 8. | Indeterminacy exists in the influencing factors and indoor air quality itself . based on assessment of indoor air quality and its application , we analyze the inherent characteristics and rules of this grey system , which generally we are short of adequate information to describe , using grey system theory . firstly , we analyze the influence of indoor air contaminations on inhabitants " subject evaluation to indoor air , and calculate the degree of grey incidence between indoor contamination level and dissatisfaction rate at indoor air or ill symptom rate 针对室内空气品质问题本身及其影响因素存在的不确定性,本文围绕室内空气品质的评价及应用,运用灰色系统理论研究了这个“部分信息已知,部分信息未知”的“小样本” 、 “贫信息”不确定系统,通过对“部分”信息的生成、开发,实现对这一系统的正确把握和描述。 |
| 9. | This study reveals the relationship between this factors , and shows which we should pay more attention to in design and maintenance of indoor environment . in order to give expression to the indeterminacy , we introduce grey structure , grey parameter and grey variable into the determinate indoor air quality models . the grey models are important tools to forecast , evaluate and control indoor contamination level , because they not only make best of the existing knowledge , but also correctly take the grey characteristics into consideration 为反映室内空气品质实际状态,我们将传统确定性模型的模型参数或系统输入进行灰化处理,引入灰结构、灰参数及灰变量,得到相应的既充分利用了人们对室内空气品质系统发展变化规律的现有认识,又对系统存在的“灰性”进行了恰当处理的室内空气品质灰色模型,为室内空气品质的评价、预测、控制和室内环境的改善提供了依据。 |
| 10. | The contribution of the paper can conclude as following : according to the laboratory investigations carried out on the ac flashover performance of two types of porcelain insulators and four types of composite insulators at the atmospheric environment of low pressure at a high altitude with pollution and icing , the relations between the minimum ac flashover voltage and the ice amount , the atmospheric pressure as well as the contamination level are obtained 本文研究的主要工作和结论如下:根据不同绝缘子在人工气候室内模拟海拔3500m以上低气压下覆冰和污秽共存环境中的交流闪络特性的试验研究结果,得出了最低闪络电压与覆冰量、海拔(低气压)和污秽度等因素之间的规律。 |
