查询词典 perfectly elastic

The simple elastic-perfectly plastic Tresca model is modified to allow for the above mentioned effects based on the finite element software ABAQUS. Then the numerical simulations for penetration resistance mechanism of T-bar penetrometer in soft clay are conducted.

在大型有限元软件ABAQUS平台上进行二次开发，针对基于Tresca屈服准则的理想弹塑性模型进行了相应改进，使之可以比较合理地反映上述因素的影响，进而对软土中T型触探仪的贯入机制进行了比较系统的数值分析。

Gases and liquids are perfectly elastic, after their being compressed they return to their original volume as soon as the applied force is removed.

气体和液体是很有弹性的。在它们受压缩以后，当施加的力一移走，它们就马上恢复原来的体积。

It can be described as the case in which the supply curves of all factors, including those of which the maximum amount available to the firm is fixed, are perfectly elastic to the industry, or in which there are no "specialized factors."

这种情况也可说成：所有要素——包括那些对厂商而言最大可用量固定的要素——的供给曲线，对行业而言都是完全弹性的，或者干脆说，其中没有"特殊要素"。

If the firm's demand curve becomes perfectly elastic the inverse of the PED will be zero meaning that the firm has zero market power.

如果一个公司的需求曲线很有弹性，则PED的反作用力为零，这就意味着这个公司毫无市场力。

DESPRIPTION】 This product adopts natural activated Collagen Peptide as its ingredient, and combines the SAYF(skin activate and youthful factor) and micro spinning technology of elastic fiber to make the eye pact perfectly fit around the eye contour, It can quickly supplement skin moisture and provide quick penetration of nutrient substance to the stratum basale under the guide of the nutrient substance penetrating absorption principle, as well as promote the vitality of skin cells, 95% of which will efficiently absorb and reserve moisture and balance PH value to make the skin elastic and soft, and significantly improve low collagen synthesis which is related to aging. It can also efficiently prevent and reduce eyes' skin wrinkles and cutis laxa to restore the eyes' skin moist and elastic, and implement the nutrition lost because of the fluctuations in temperatures to promote the natural moisture ability of the skin around the eyes to make those skin instantly moisturized, smooth, refresh and outstanding radiant. The wrinkles and fine lines will be reduced at the same time, and the black circles will be no longer apparent.

本品采用天然的活性胶原蛋白多肽为原料，独有的SAYF融合弹性纤维的微纺技术，完美贴合眼部轮廓，可快速补充皮肤在外界所流失的水分，功效营养物质通过透皮吸收原理，快速渗透到皮肤的基底层，并渗提高皮肤细胞活力，其95%有效吸收留住水分，平衡PH值，使皮肤增加弹性和柔软性；明显改善与老化相关的胶原合成低下的现象，有效预防和减少眼部肌肤皱纹及松弛的现象，恢复润泽和弹性，同时补充眼部皮肤在各种温度不定的情况下流失的营养，提升眼周肌肤自然储水力，双眸瞬间滋润、光滑、丰盈，焕然一新，细纹与皱纹减少，黑眼圈变得不再明显。

Weibull distribution function is used to characterize phenomenologically the debonded probability of the interface, which is decided by the tensile stress of the particle. A partially debonded isotropic spherical elastic particle is replaced by an equivalent, perfectly bonded spherical particle, which possesses yet unknown transversely isotropic elastic moduli. The fictitious particles can be determined in such a way that their tensile and shear stresses will only vanish in the debonded direction.

认为颗粒增强金属基复合材料的界面脱黏受控于颗粒所受的拉应力，引入Weibull分布函数描述颗粒脱黏概率，且受单向拉伸载荷作用时，仅在沿受力方向的上下两侧发生部分界面脱黏，从而将部分脱黏的各向同性颗粒由一完好的横观各向同性颗粒来等效，建立了部分脱黏模型。
