查询词典 stress function

The contents of Chla and Car were sensitive to low temperature stress, it seems that they were vulnerable to low temperature stress and partly decomposed. Relatively, the content of Chlb changed little. The ratio of Chla/b had positive linear correlation with temperature, which meant the photosynthetic ability of podocarpus fleuryi Hickel seedlings declined under winter low temperature stress.

叶片中叶绿素a和类胡萝卜素含量对低温胁迫反应较为敏感，容易遭受低温胁迫而部分地分解破坏，含量下降，而叶绿素b则相对变化较小，Chla／b值呈现与温度的线性正相关，显示了长叶竹柏幼苗在冬季低温胁迫下光合能力的下降情况。

To study the ecophysiological effects of low temperature stress on podocarpus fleuryi Hickel seedlings, two-year-old seedlings were selected as experimental material. We conducted comparative study. On the one hand, seedlings were separately placed in the plots located at the top, half-way-up and the foot of Jinyun Mountain (different altitudes at Jinyun Mountain led to the difference in air temperature) and subjected to winter low temperature stress. On the other hand, in laboratory, seedlings were exposed to simulated low temperature stress which were artificially controlled .

为了探讨低温胁迫对长叶竹柏幼苗的生理生态影响，本试验选取长叶竹柏的二龄幼苗为试验材料，在试验方法上采取了对比研究方法：一方面，利用缙云山不同的海拔造成的温度差异，分别将幼苗置于山顶、山腰和山脚下三个样地中，进行野外冬季自然低温胁迫处理；另一方面，在实验室中，利用人工控制的不同低温进行模拟低温胁迫处理。

A new cyclic constitutive model for sands which can describe the deformation behavior of sands under combined variation of principal stress axes and magnitudes was developed based on the above physical fundamentals. And its effectiveness under the complex stress paths including cyclic rotation of principal stress axes is verified by a good comparison of model simulation with test results for sands.

2基于对应力主轴循环旋转条件下砂土的基本变形规律的认识，吸收和借鉴已有弹塑性本构模型研究成果中的合理概念和建模方法，建立了一个可合理描述应力主轴循环旋转效应及主应力幅值大小与应力主轴方向循环耦变效应的砂土弹塑性本构模型，并对该模型在包含应力主轴旋转的复杂循环应力路径下的有效性进行了验证。
