查询词典 elastica

In this paper we study the deformation and stability of a planar elastica. One end of the elastica is clamped and fixed in space. The other end of the elastica is also clamped, but the clamp itself is allowed to slide along a linear track with a angle different from that of the fixed clamp.

於本文将探讨弹性板条的变形与稳定性，弹性板条的一端夹持住且固定於空间中，另一端同样夹持住但角度不同於固定端，且可沿角度方向直线的自由滑动。

The elastica deforms after it is subject to an external pushing force on the moving clamp. It is observed that when the pushing force reaches a critical value, snapping may occur as the elastica jumps from one configuration to another remotely away from the original one. Moreover, in order to transfer motion or force by this structure, we will make a research into the relation between longitudinal forces of the two ends.

在对滑动夹持端施以推力后，弹性板条会产生变形，我们观察到当推力达到临界值便会发生折断式挫曲的现象，由原先的变形跳至另一稳定的变形；此外，希望以此结构传递运动或力量，故将对两端的轴向力关系加以研究。

Using shoot tip of Ficus elastica 'Decora Burgundy' as explants, Using MS as basic medium with different hormone combinations and selected the best medium combination to set up the plant regeneration system of Ficus elastica 'Decora Burgundy'.

方法］以印度橡胶榕&黑金刚&茎尖为材料，以MS为基本培养基添加不同的激素组合进行组织培养，选择最佳的培养基配方。

They can be classificated to two kinds. One kind is build by photomultiplier; another kind is build by MCP. The mechanism of delayed luminescence is discussed with subradiation. A photon count system is built. To proof the biophoton is a kind of ultra weak photon stream originate from exothermic reaction, and primarily discuss the relationship between the delayed luminescence and proteins activity, we chose microphyllous banyan leave , ficus elastica leave, gingkgo leave, Chinese fan palm leave, and cinnamomum camphora leave as biological samples. The ultra weak photon emission from normal biosamples, and proteins inactivated biosample were measured separately with photon count system. The results showed that the delayed luminescence of biosamples have

在研究过程中，作者从辐射陷获的角度讨论了延迟发光的产生机制，对生物光子的生物化学起源与相干场起源的统一性进行了探索；自行搭建了单光子探测系统；测量了小叶榕树、印度橡树，银杏树，蒲葵树香和樟树等多种植物叶片样品的延迟发光，获得了大量实验数据；为了证明生物光子是一种起源于放热化学反应能量释放的微弱光子流，并初步探讨生物蛋白活性与延迟发光衰减之间的关系，测量了正常生物样品、生物蛋白灭活样品的延迟发光，同时测量了多种不含蛋白质的无机化学体系作为比对，实验结果和实验数据的回归分析表明：弱光子发射来源于放热的化学反应，延迟发光的强度与衰减时间与生物蛋白活性密切相关。

In section 4.2, we study the rescaled WLC model which is equivalent to Langer and Singer's theory of elastica because the Gauss curvature equals zero in three-dimensional Euclidean space.

我们首先讨论了Feoli 等人的结果，将之作为自由能仅为曲率的泛函的特例纳入普遍形式理论中来；并研究了Langer 和Singer 提出的关于弹性曲线的理论(即重新标度的WLC模型)，与当前理论符合得很好。
