In the presence of strong absorption and at an intensity higher than the intensity scale characterizing the region of weak field shielding, the time dependence of the total current is nonmonotonic.


The mean visual analog pain intensity scale improved from 8.3 to 4.0 postoperative and 4.8 at followup (p>amp;lt;0.05).


All patients completed selfadministered questionnaires, Oswestry Low Back Pain Disability Score (ODS), Roland Morris score (RLS), and Visual Analog Pain Intensity Scale (VAS).


The outcome was evaluated using the Oswestry low back pain disability score and the visual analogue pain intensity scale.


When the pain intensity scale was analysed, PCA+FLC patients had acceptable pain intensity at 62%, compared with 44% in conventional PCA.

One of the dimensions corresponds to a subjective scale of intensity, with a zeropoint lying outside of the configuration.




 The concept of earthquake intensity is reexamined. It is pointed out that earthquake intensity is the average degree of ground shaking in an area and can only be measured by physical quantities averaged over the said area. Engineering data should be determined by the average value plus certain deviation chosen on sound probabilistic basis. At present stage, both macroscopic and physical scales are needed, with the latter as standard and the former as qualitative description of the latter. Problems, such as... The concept of earthquake intensity is reexamined. It is pointed out that earthquake intensity is the average degree of ground shaking in an area and can only be measured by physical quantities averaged over the said area. Engineering data should be determined by the average value plus certain deviation chosen on sound probabilistic basis. At present stage, both macroscopic and physical scales are needed, with the latter as standard and the former as qualitative description of the latter. Problems, such as the choice of physical measures, the revision of current intensity scale and the application of intensity in engineering practice are discussed at length.  本文对地震烈度这个概念作了重新审查,指出地震烈度是地面震动在一定面积范围内的平均程度,只能用在此范围内平均的物理数量来度量.在现阶段,工程设计数据应当选取这个平均数量加上一定的具有合理概率基础的偏差.宏观的和物理的烈度尺度都是需要的,但须以后者为准,以前者为后者的定性描述.对于物理尺度的选择、现行烈度表的修改以及烈度在工程实践中的应用等问题都作了较详细的讨论.  Concept of linguistic variable in fuzzy set theory is introduced firstly and then, referring the resulting figure of relation between earthquake intensity and damage conditions of second class building outlined in reference [3], earthquake intensities VX are defined as the fuzzy subsets in universe of discourse with building, damage indices as its base variables which were established by field investigations of past earthquakes.Secondly, using the concepts and methodologies of evidence analysis and fuzzy conditional... Concept of linguistic variable in fuzzy set theory is introduced firstly and then, referring the resulting figure of relation between earthquake intensity and damage conditions of second class building outlined in reference [3], earthquake intensities VX are defined as the fuzzy subsets in universe of discourse with building, damage indices as its base variables which were established by field investigations of past earthquakes.Secondly, using the concepts and methodologies of evidence analysis and fuzzy conditional inference rule and based on 117 pairs of intensityacc. data recorded in recent strong earthquakes, information structures of data and their effects on computational results are analysed. Fuzzy relationship between intensity and ace. is established. Higher as well as lower possibilities of the estimations of ace. suggested in<1980 Seismic Intensity Scale of China>are figured out.Sensefulness of this article is that the socalled bu lding damage index is really related with physical quantity of ground motion in some fashio'n, so its mathematical meaning is enhanced in somewhat and marks a new way in treating with seismological as well as earthquake engineering problems.  本文研究“中国地震烈度表(1980)”建议的地面加速度峰值的可靠性问题。 文中使用模糊集合理论的概念和方法,建立了烈度(以平均房屋震害指数为度量标准)与地面运动之间的模糊关系,从而在没有强震记录情况下,可以反推地面运动,适当弥补缺乏仪器记录之不足。  In this paper, the earthquake intensity is firstly treated as a fuzzy subset of an universe of discourse using building damage indices due to earthquake as its base variable, and then various membership functions corresponding to the fuzzy subsets for intensities from Ⅵ° to Ⅹ° are determined based on data of field investigations of a number of past earthquakes in China. By means of direct method in pattern recognition and acut notions, the relationships between intensities and damage indices are figured out.... In this paper, the earthquake intensity is firstly treated as a fuzzy subset of an universe of discourse using building damage indices due to earthquake as its base variable, and then various membership functions corresponding to the fuzzy subsets for intensities from Ⅵ° to Ⅹ° are determined based on data of field investigations of a number of past earthquakes in China. By means of direct method in pattern recognition and acut notions, the relationships between intensities and damage indices are figured out. For intensities from Ⅷ° to Ⅹ°, these relationships are completely coincided with those suggested in 《 1980 Seismic Intensity Scale of China》, but there are some differences in intensities Ⅵ° and Ⅶ°. The results obtained here is useful in evaluating earthquake intensity in practice.  本文把地震烈度作为震害(以震害指数为基础变量)论域中的模糊子集,确定了烈度模糊集Ⅵ一Ⅹ的隶属函数;用模式识别的直接方法和α截集的概念得到了烈度和震害指数的两种对应关系,在Ⅷ、Ⅸ、Ⅹ度,这些关系和《中国地震烈度表(1980)》完全一致,而在Ⅵ和Ⅶ度则有所不同。这些结果可直接应用于烈度评定工作中。   << 更多相关文摘
