Although cell-in-cell structures (CICs),with one or more cells present inside an-other cell,had been identified for a cen-tury,it was not until recent years that scientists started to uncover their piv-otal roles in multiple biological pro-cesses,primarily via mediating the death of internalized cells.

将可再生能源发电丰沛期的电量用于电解水制氢并存储被认为是应对可再生能源发电不稳定缺憾的重要解决方案之一.氢气的比能在所有的燃料中最高,但其能量密度较低,存储一直是世界性难题,大量存储则更加困难.随着氢气存贮技术的不断进步,地下存储或地质存储被视为大规模储氢技术最具可行性的发展方向.

鄂尔多斯盆地为典型的克拉通内盆地,油、气、煤、盐、铀等矿产资源丰富.研究构造运动的期次、序列与性质将为揭示克拉通盆地的成因与演化过程奠定基础,同时也将为探讨多种能源、矿产资源赋存的内在机制提供依据.基于近年来的高精度区域反射地震剖面和深井资料,结合周缘地质露头分析,通过厘定鄂尔多斯盆地的关键构造变革时期,建立了盆地演化的时-空框架.研究表明,鄂尔多斯盆地由下至上发育10个区域不整合面,分别为长城系、蓟县系、震旦系、寒武系、奥陶系、石炭系、三叠系、侏罗系、白垩系和第四系底界不整合面;盆地发育中元古界、寒武系
当沉积盆地累计产量超过50×108 bbl油当量(6.82×108 t油或7931.66×108 m3气)和剩余可采资源量超过50× 108 bbl油当量即称之为超级盆地.四川盆地至2019年底油气总产量为6569×108 m3,气油比为80∶1,总剩余可采资源量达136404× 108 m3,属二级超级盆地;由于产出以气为主,故为超级气盆地.四川盆地之所以成为超级气盆地,因其具有4个优势:①气源岩优势,有9组主要气源岩,为全国各盆地之首;②资源量优势,总剩余天然气可采资源量为136404×108 m3,
