重庆大学学报 , 2003, DOI: 10.11835/j.issn.1000-582X.2003.10.018
Abstract: 植物的次生代谢是植物在长期进化中与环境(生物的和非生物的)相互作用的结果,次生代谢产物在植物提高自身保护和生存竞争能力、协调与环境关系上充当着重要的角色,其产生和变化比初生代谢产物与环境有着更强的相关性和对应性,环境应力的改变对植物次生代谢产物的形成作用非常显著。次生代谢是一个研究难度大但又极具潜力的研究领域。随着对次生代谢生理生化及生态适应方面认识的深入,以及分子生物学手段的渗透,植物次生代谢分子调控的研究发展迅速。从物理刺激、干旱、高盐分、动物、微生物等方面综述了环境应力对植物次生代谢产物形成作用的研究进展。

Abstract: 为探讨乘客身材特征对地铁客室中乘坐设备功能尺寸设计的影响,运用人机工程学以人为中心的实验和相关分析法展开研究.围绕人的生理结构、心理尺度和乘坐设备的功能属性等因素,结合压力分布实验、虚拟仿真技术和主观评价分析,对人与地铁座椅和扶手之间的功能尺寸配置关系进行了测试与分析.研究结果表明:座椅腰靠纵向外凸圆弧的曲率半径为186 mm、座垫横向内凹圆弧的曲率半径为785 mm时更贴近人体坐姿的生理曲度和满足乘坐的舒适性要求;扶手的吊环高度设置在1 710 mm、横杆高度设置在1 860 mm时能够分别保障不同身材的乘客的使用需求,并能满足适用性、安全性和通行性之间的平衡.
:A human-centred experiment and ergonomic correlation-analysis approach was adopted to investigate the impact of passenger body size on the functional dimension design of riding equipment in subway passenger compartments. Subsequently, the relationship between the functional dimension configuration among passengers, subway seats, and handrails was tested and analysed based on human physiological structure, psychological endurance, and functional properties of riding equipment. This was achieved by combining a pressure distribution experiment with virtual simulation technology and subsequent subjective evaluation and analysis. Results demonstrate that when the curvature radius of the backrest outer convex arc measures 186 mm while that of the cushion inner concave arc measures 785 mm, seat surface closely matches the physiological curvature of the body-sitting posture, thereby meeting the requirements of riding comfort. Also, when the height of handrail rings and that of cross rods are set as 1 710 mm and 1 860 mm, respectively, handrail height meets usage requirements of passengers having different bodies sizes as well as that of balance between applicability, safety, and accessibility

全息云纹法的傅里叶解释

重庆大学学报 , 1989,
Abstract: 自从D.Post提出全息云纹干涉技术后,现已发展到各个方面,如断裂力学、复合材料力学、生物力学的性质测试上等均有应用。然而,对全息光栅、全息云纹技术在理论上发展存在欠缺。本文用傅里叶光学理论推导全息光栅的栅频、全息云纹的位移公式,进一步完善了全息云纹技术的理论,为全息云纹技术广泛应用提供了理论依据。

Abstract: Using the methods of the wavelet transform and the nonlinear dynamics, the behavior of chaotic signals in phase space is studied. It is indicated that, in phase space reconstruction, the wavelet transform of chaotic time series is essentially a projection of strange attractor on the axis of the space that filter vectors opened, which in correspondance with the method of phase space reconstruction proposed by Packard et al. The experimental results show that, after doing wavelet transform, the architecture of attractor trajectory is similar to the original one, and the nonlinear invariants such as correlation dimension and Kolmogorov entropy are reserved. These results show that wavelet transform is effective for studying chaotic signal.

Abstract: 西北次海盆是南海海盆的一个重要构造单元,揭示西北次海盆的地热流特征对于整体认识南海海盆热状态和热结构至关重要.沿着OBS2006-1地震剖面采集的一批实测地热流数据显示,该热流探测剖面横穿南海北部陆坡、西北次海盆、中沙隆起、东部次海盆4个构造单元,结合地震解释剖面等资料对西北次海盆进行地热流特征分析及研究.结果表明:西北次海盆的平均热流密度值为104.5±9.9 mW/m2,与中沙隆起相邻的东部次海盆北部的平均热流密度值为97±2.5 mW/m2,热流密度值的空间变化与地幔埋深起伏相对应,并受地幔热源所控制;通过研究热流异常点,发现水深相近的相邻站位之间的海底表层沉积物温度差异是判别测站受海底地下水热循环影响程度和类型的依据之一;用最新海洋地热流探测成果,结合区域地质与地球物理资料,推测西北次海盆形成演化时代与西南次海盆相近,只是它的生命史比较短暂.
The Northwest sub-basin (NW sub-basin) is an important tectonic unit in the South China Sea. It is of great importance to reveal the geothermal characteristics of the NW sub-basin for the better understanding of thermal and thermal structures of the basins of South China Sea. We have collected a series of measured heat flow data along the OBS2006-1 seismic profile. This heat flow profile crosses four tectonic units, including the northern slope of the South China Sea,the NW sub-basin,the Zhongsha rise and the east sub-basin. With the seismic interpretation profile,this paper analyzes and studies in detail the heat flow characteristics. The results show that the average heat flow value is 104.5±9.9mW/m2 in the NW subbasin,and the average heat flow value in the northern part of the East subbasin is 97±2.5mW/m2,the change trend of the heat flow values is similar to that of the Moho depth,which manifests that the deep thermal state is controlled by the source of mantle heat. By studying the anomalies of heat flow,it is found that the temperature difference between the seabed surface sediments in adjacent sites is one of the basis for judging the degree and type of groundwater thermal cycling. With the latest ocean heat flow detection results,combined with regional geology and geophysical data,it is suggested that the formation of the NW sub-basin is similar to that of the Southwest sub-basin,but with relatively shorter history
