查询词典 asymmetric relation

The asymmetric coefficients of debris flows are quite different in different area: large asymmetric coefficients of debris flow with low resistance; small asymmetric coefficients of debris flow with high resistance. The asymmetric coefficients of debris flow could be used to classify resistance characteristics of debris flow accurately and the resistance law of viscous debris flows was got by asymmetric coefficients.

泥石流的不均匀系数在不同的泥石流地区有很大的不同：不均匀系数小的地区阻力大，而不均匀系数大的地区阻力小，因此可以用不均匀系数划分泥石流沟的阻力特征，从而得到能兼顾所有不同地区的泥石流阻力规律。

这是影响国人正确认识公共关系的最大&误区&，由此产生了一系列十分消极的社会负面效应，如不少国人把公关与&私关&———拉关系、走后门的庸俗关系以及社会不正之风等同起来，还出现了为数不少的假公关之名、行&私关&之实的&公关败类&；更令人啼笑皆非的是，人们甚至把社会上猖獗一时的&三陪现象&与公关相提并论。

A systematic study of correlation between nose disturbances and evoluted behaviors of asymmetric vortices over slender body models has been conducted. The new flow phenomena have been revealed in which the two-cycle behavior of Cy vs.γ curve for asymmetric vortices flow is continuously changed into one-cycle behavior with increasing of disturbance strength on the model nose tip. This newly found flow phenomenon is important and it provides a physical flow base to the perturbation active control of forebody asymmetric vortices flow.

The results showed that the CV performance of PbO〓/PbSO〓 and PbSO〓/Pb powder microelectrode transformed from PbCO〓 under the optimize condition (the positive electrode was activated by asymmetric CV and asymmetric square wave current ways and the negative electrode using asymmetric CV) were better. Their electrode performances were as good as those made from leady oxide product by ball mill under the same conditions.

It is revealed that the asymmetric vortices over slender body are formed the breakaways of higher position vortex and generation of new vortex, which are alternately developed on the both sides along the body axis. The correlation between asymmetric vortices structure and distribution of sectional sideforce coefficient has been obtained. A physical model of asymmetric multi-vortices flow structure is developed according to zonal flow analysis.

With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.
