查询词典 at fault

Aiming at the signal processing problems that exist in online fault diagnosis for train running gear, based on discussing the principle of characteristic spectrum analysis, a method of full period and uniform angle sampling is applied, which transfers the vibration signal from time domain into angular domain. The angular domain signal is transferred into corresponding characteristic spectrum using FFT. Through spectrum estimation and analysis, fault characteristic spectrum values of running gear components are acquired to distinguish their faults.

从目前国内外在构造反演这一问题的研究现状来看，在拉张构造区域，反演问题在理论上有比较多的模拟解决办法，并且应用的相当成功，不过考虑到有些特殊的情况，比如逆牵引构造所派生的次级断裂会造成反演计算结果的不准确，因此对现存的反演模型稍微做出了点修改，使之更能广泛的应用于实际的构造解释。

Aim at the defect of commonly technique,a new technique of alarm in advance of boiler water level is put forward.this technique adopt the idea of signal catenation and blur control.alarm in advance and seek out the coming fault.the fault can be repaired before water level beyond the limit.avoiding water level beyond the limit.

针对一般方法的弊端，提出一种新颖的汽包水位预警的方法。该预警系统采用信号间的连锁和模糊控制的思想，在故障发生以前提出预警，并且找出可能发生的故障。从而达到在水位越限以前进行故障检修，避免水位越限。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

将盾构隧道常见病害成因分为管片错位、衬砌材质劣化以及渗漏水等6个子系，对每个子系构建了病害故障树；从工程应用角度出发，从故障树中选取了23个可定量化因素作为评价指标，通过层次分析法建立了三层病害评价指标体系；对体系中单一评价指标的定量化分级方法进行简述，并给出所有指标的建议分级标准，采用改进的层次分析法－乘积标度法确定了各评判指标之间的相对权重；确定了基于Cauchy分布模型的隶属函数的关键参数。

If the tectonic uplift is not considered, the relief of Dabie orogen will reach at least 3km in Late-Cretaceous. As to the value of the relief reduction factor in Dabie orogen at 90Ma, the largest value appeared in northeast region, followed consecutively by the core and southeast Tanlu fault zone, with the smalleast value appeared in northwest and southwest region. The results reflect the strong uplift difference between core and North Huaiyang flank in Dabie orogen during doming extension period. Relief in the core region and southeast Tanlu fault zone is higher than those in the peripheral regions, northwest and southwest flanks are more stable than other regions.
