低阻经络研究Ⅱ、健康人常态低阻经络的分布   总被引:3,自引:2,他引:1  
测量皮下电阻,联接低阻点,绘出了人体低阻经络模式图。此模式图与传统经络图符合很好。由此说明经络确实是存在的,并具有电阻率较小的特性。  相似文献

实验研究了泡沫铝夹芯梁结构在不同温度下的3点弯曲力学性能.通过引入Gibson模型构建夹芯梁架构在3点弯曲作用下的失效模式图,并将失效模式图扩展到高温情况下,得到泡沫铝夹芯梁的初始失效模式图随温度的变化趋势.结果发现,其他因素不变,随着温度的升高,夹芯梁结构更容易发生面板屈服失效模式,芯层剪切模式涉及的范围被大大压缩.根据修正的Gibson模型预测的夹芯梁结构的极限载荷和实验结果所得极限载荷比较发现,芯层剪切模式分析结果和实验数据很好地吻合,说明泡沫铝夹芯梁的最终失效破坏主要是由于芯层剪切引起的.  相似文献

木素的化学结构是天然高分子化合物中最大的难题之一。借助现代分析手段,如IR、UV、NMR、ESR以及生物合成法等,使人们基本上了解了针叶木木素的化学结构概况,但是对阔叶木木素和草类木素的化学结构,目前还不十分清楚。木素的化学结构包含有它的建筑石、功能基、侧链和联结类型,以及与之相连的其它物质。这样,便可描绘出木素的真实结构。近年来对木素化学结构的研究很多,最新成果集中反映在木素的结构模式图上。不过,现有的模式图还存在着若干不完善之处。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the  相似文献
