The great Wenchuan earthquake(Ms = 8.0) in 2008 caused severe damage in the western part of the Chengdu Plain.Soil liquefaction was one of the major causes of damage in the plain areas,and proper eval
In this paper,analytical results from 3D temporal characteristics of the responses of an RC frame building subjected to both a large aftershock and the main shock of Wenchuan Ms8.0 earthquake are pres
In order to carry out numerical simulation using geologic structural data obtained from Landmark(seismic interpretation system), underground geological structures are abstracted into mechanical models
本文研究了无光照异养条件下八种金属离子对小球藻Chlorella vulgaris的生物量和总脂肪酸含量(TFAC)的影响。Cu2+,Zn2+是小球藻生长的限制性营养因子,通过添加0.08mg/LCuSO4·5H2O可使小球藻生物量从1.24g/L提高到3.60g/L;添加0.2mg/LZnSO4·7H2O,可使小球藻生物量从1.71g/L提高到3.96g/L。Mg2+缺失条件可得到最高总脂肪酸含
The 8.0 Mw Wenchuan earthquake triggered widespread and large scale landslides in mountainous regions.An approach was used to map and assess landslide susceptibility in a given area.A numerical rating
In order to in situ measure chemical parameters of deep-sea water and hydrothermal fluids at midocean ridge(MOR), it is necessary to use high temperature and high pressure chemical sensors.Developing
基于质量传递与热量传递现象之间的类比性,引入了质量积的概念来代表物体向外界传递质量的能力,定义了质量积耗散函数,说明了质量积耗散是传质过程不可逆性的量度,提出了质量积耗散极值原理和优化对流传质过程的优化方法,在一定约束条件下导出了对流传质性能最佳时流体流动所需满足的欧拉方程.在此基础上,对空间站实验舱内通风排除气体污染物的过程进行了优化来达到减少通风系统能耗,降低实验舱内污染物浓度的效果.结果表明
The role of jasmonic acid (JA) in plant wounding response has been demonstrated.However,the source of JA in wound signaling remains unclear.In the present study,pea seedlings were used as material to
Aluminum-induced secretion of organic acids from the root apex has been demonstrated to be one major Al resistance mechanism in plants.However,whether the organic acid concentration is high enough to
Carbonate pedofeatures (CPs) in a chronosequence of paleosols buried under kurgans in the Northern Caucasus region of Russia in a period from the end of the 4th to the middle of the 5th centuries AD (
