查询词典 cog-wheel respiration

Statistic analysis showed that soil temperature as the driving factor to the diurnal variation of soil respiration. Soil temperature and soil moisture were the dominant environmental factors affecting the seasonal variation of soil respiration and explained 87% of its variability. LAI and root biomass were positively related to soil respiration rate, indicating that biotic factors also affected the seasonal variation of soil respiration. However, soil properties such as soil organic content, total nitrogen content, and C/N ratio had poor correlations with soil respiration. Top-dressing nitrogen fertilizer increased soil respiration significantly.

统计分析表明：土壤温度是玉米生态系统土壤呼吸日变化的驱动因素；土壤温度和土壤水分是影响土壤呼吸季节变化的关键因素，二者可以解释玉米生长季土壤呼吸时间变异的87%；LAI和根系生物量与土壤呼吸速率呈正相关，说明生物因子对土壤呼吸季节变化也有影响；土壤有机质、全氮和碳氮比等土壤理化特性与土壤呼吸速率的关系较弱；玉米生长季追施氮肥明显促进土壤呼吸速率。

In the analysis, firstly, the flux boundary condition is used to simulate the frictional heat resource between wheel and rail. The non-steady heat transfer between the contacting surfaces of the wheel/rail, heat-convection and radiation between the wheel/rail and the ambient were all taken into consideration. Therefore, a heat coupling model of the wheel/rail in rolling/sliding is put forward to calculate the frictional temperature rise in the wheel and rail. Secondly, after the temperature distribution of wheel/rail, due to friction, is calculated, substitute the thermal load with equivalent fictitious body force and boundary distributed force loaded on the nodes of the corresponding elements. The wheel-load is applied to the center of the wheel.

首先，用热流边界条件模拟轮轨接触界面的摩擦热源，考虑轮轨间的非稳态热传导、轮轨自由表面与环境的热对流、热辐射的影响，建立轮轨滚动接触热耦合有限元计算模型，分析计算轮轨滚、滑工况下的摩擦温升；其次，以求得的轮轨温度场结果作为求解轮轨应力场的已知条件，轮载以集中力形式直接加载于轮心处，将摩擦温升引起的热载荷等效为假想体力和热边界面力，施加于相应的单元节点上，建立了轮轨热—机械载荷耦合作用的热弹性平面应力模型，分析热—机械载荷作用下的轮轨应力场。

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。

The main results were as follows:'Brumal jujube' with higher respiration rate, which decreased slightly after harvest, and lower ethylene production, which had not the appearance of respiration and ethylene production peak, ethephon with different concentrations all increased respiration rate and the respiration rate increased with the raise of concentration ,which suggested 'brumal jujube ' was respiratory non-climactic fruits.

结果如下：冬枣采后果实呼吸强度高并呈平缓下降趋势，而乙烯释放量较低无明显高峰出现；不同浓度的乙烯利处理增加了果实呼吸强度，处理浓度越大，果实呼吸速率越高，说明冬枣为非跃变型果实；1000μL.L~(-1)乙烯利和100mg.L~(-1)ABA处理可显著提高绿熟冬枣采后的呼吸强度，两者无明显差异，但乙烯利处理显著增加了乙烯释放量、ACC含量和ACO活性，其作用比ABA明显；GA处理抑制了果实呼吸强度和乙烯释放量的增加。
