5水库荷载对坝的应力和变形的影响显示文摘技术文献中所报道的观测结果证明,各种大坝(土石坝、重力坝、拱坝等等)都受水库水荷载引起水库变形的影响. 大坝的实测变形值常比理论计算的变形值小.原因之一是水库蓄水后,库底和库壁在水荷载作用下产生沉陷所致.这种沉陷在坝上游一段距离处最大,它引起坝基向上游转动,引起坝顶向上游偏移,这就抵消了一部分由于作用在坝上的静水压力和河谷展宽所引起的向下游方向的偏移.M.A.M赫尔措格 胡卫东 付湘宁 1990人民长江1990,21,11:0
6Nano to micro size transition of hydroxyapatite in porcine bone during heat treatment with low heating rates显示文摘This work focuses on the changes of raw hydroxyapatite obtained from porcine bones during heat treatment with heating rates of 2.5 and 5.0℃/min between 600℃and 1100℃.High-Resolution transmission electron microscopy(HR-TEM)images showed that raw hydroxyapatite was formed by high-ordered nanometric platelet crystals with a length of around 18 nm and width around 7 nm.High-Resolution scanning electron microscopy(HR-SEM)images evidenced the coalescence phenomena during heating giving.It was found that the growth of the crystals and the transition from nano to a micro-size occurred at around 700℃.And the changes in the full width at half maximum(FWHM)for the characteristic(002)plane of the X-ray diffraction patterns and the FWHM of the characteristic Raman band at 960 cm-1 for i/l P043-exhibited the transition from nano to a micro size,that was confirmed by HR-SEM images and the thermogravimetric(TG)analysis.The porosity of the BIOHAp changes from intra nanometric to intercrystalline.Angelica M.Castillo-Paz Sandra M.Londono-Restrepo Liliana Tirado-Mejfa M.A.M ondragon Mario E.Rodriguez-Garcia 2020Progress in Natural Science:Materials International2020,30,4:0
