查询词典 Hooke

The stress was applied by a helix micrometer. The in-plane compressive or tensile strains were created and the stress in the sample can be calculated according to Hooke's law.

层结构的应力由螺旋测微器施加，可以产生平面内的压应力和应变，大小可以由胡克定律算出。

Based on wave propagating in three directions of elastic foundation, vibrating displacement could be assumed to be in three forms along three directions. Hooke's law and theory of waves were adopted to deduce the formula of coupled viscous boundary. The coupled viscous boundary could be applied in finite element method.

根据波在地基的3个方向都可以进行传播的特点，假定了地基中质点沿3个方向的振动表达式，通过胡克定律和波动理论，推导了弹性地基中三维动力问题的耦合粘性边界的公式。

Hooke's Law of Elasticity?

胡克定律？你说呢？

From 1665 he taught at Oxford University. His achievements and theories were bewilderingly diverse. His important law of elasticity, known as Hooke's law (1660), states that the stretching of a solid is proportional to the force applied to it.

英国物理学家。1665年起在牛津大学任教，在各领域的成就和理论贡献卓著。1660年提出重要的弹性定律－－虎克定律，说明固体的伸长量与所受的力成正比。

The classical elastic theory is precisely based on the Hooke's law, and issuitable to the depicting and describing of seismic wave propagation in the elasticmedia. But either from the experimental results of testing on the core, or from thepractical results of exploration and exploitation in the oilfield, the subsurface mediumshows more or less the non-elastic characteristics, namely viscoelastic behavior.

经典的弹性理论是建立在精确遵守虎克定律的基础之上的，弹性波动理论适用于对弹性介质中传播的地震波的刻画和描述，但是无论是对地下岩芯的实验室测试，还是油田的勘探开发实践，都已经证实地下介质或多或少地表现出非完全弹性，即粘弹性行为。

K. H. Roscoe and his fellows of Cambridge University established the first elastoplastic model of soils which is based on classical plastic theory in 1963. However, due to the complexity of soils, the models that based on the classical metal constitutive theory or its modification accounting on the nature of soils have still much limitation when used to express the soil mechanical behavior. For example, the Duncan-Chang's model based on the generalized Hooke's law can not express the dilatancy of the soils. The uniqueness assumption of the direction of the incremental plastic strain in the classical plastic constitutive theory is not in agreement with some soil experiments.

但由于土的复杂性，目前以传统的本构理论为基础考虑土的一些特性而建立的模型在反映土体的力学特性上还存在很大的局限性，如建立于广义虎克定律基础上的Duncan—Chang模型不能反映土的剪胀性，传统的塑性本构理论中认为塑性应变增量方向具有唯一性的假设与一些土体的试验结果不符合。

To determinate volumes and directions of the principle stresses, constantly three 1/4-bridges should be applied to measure normal strains along three sensitive grids. Based on the analysis of the plane stress state and generalized Hooke's law, volumes and directions of the principle stresses at one point will be obtained.

在该实验中，为了测量构件表面一点的主应力大小及方向，通常采用3个1/4桥路，测量该点沿3个敏感栅方向的线应变，根据平面应变状态分析和广义胡克定律求得该点的主应力大小及方向。

Methods and results We assume the carotid arterial wall is the elastic material so we can use the Hooke's law to analyze it. The experiment is based on the use of ultrasound B-mode imaging technique and the off-line image analysis. Elastic tube phantom experiments demonstrated the validity of the technique, providing the size of the tube within 3% of the actual values. The system was also tested in the common carotid arteries of 10 healthy males (age 23.6 y). According to the experimental result, it shows that our index is less variant than Peterson's elastic modulus. The results of and are and respectively.

根据橡皮管的体外实验结果，利用超音波以及影像分析所得到的橡皮管尺寸，与实际尺寸间的误差只有3%，而使用超音波 B-mode 量测颈动脉的实验结果显示，在把颈动脉当作完全弹性体的假设下，所得到的 CIMT 硬度指标，於十位平均年龄为23.6岁的年轻健康男性中，结果与过去文献中常使用的 Peterson's elastic modulus 相比较，结果显示容易受到不同受试者间，不同的生理状态之影响，而在考虑受试者的 IMT 变化情况下，比能够反映更多的受试者颈动脉材料性质，因此得到了较为稳定的实验结果。

The simplified Phillips' differential equation of tension which derived from Hooke's law on the assumption of uniform strip section is conventionally used up to date for the computation of cold tandem rolling.

目前常用的冷连轧张力微分方程dt=E/Lν_b(i+1-ν_dτ是假设机架间的带钢具有均匀的断面，引用等断面直杆虎克定律导出的，故为等断面张力微分方程。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
