The Bohai Bay Basin is a Mesozoic subsidence and Cenozoic rift basin in the North China Craton. Since the deposition of the Permo-Carboniferous hydrocarbon source rock, the basin has undergone many tectonic events. The source rocks have undergone non-uniform uplift, twisting, deep burying, and magmatism and that led to an interrupted or stepwise during the evolution of hydrocarbon source rocks. We have investigated the Permo-Carboniferous hydrocarbon source rocks history of burying, heating, and hydrocarbon generation, not only on the basis of tectonic disturbance and deeply buried but also with new studies on apatite fission track analysis, fluid inclusion measurements, and the application of the numerical simulation of EASY % Ro. The heating temperature of the source rocks continued to rise from the Indosinian to Himalayan stage and reached a maximum at the Late Himalayan. This led to the stepwise increases during organic maturation and multiple stages of hydrocarbon generation. The study delineated the tectonic stages, the intensity of hydrocarbon generation and spatial and temporal distribution of hydrocarbon generations. The hydrocarbon generation occurred during the Indosinian, Yanshanian, and particularly Late Himalayan. The hydrocarbon generation during the late Himalayan stage is the most important one for the Permo-Carboniferous source rocks of the Bohai Bay Basin in China.

To improve the grinding quality of robotic belt grinding systems for the workpieces with complex shaped surfaces, new concepts of the dexterity grinding point and the dexterity grinding space are proposed and their mathematical descriptions are defined. Factors influencing the dexterity grinding space are analyzed. And a method to determine the necessary dexterity grinding space is suggested. Based on particle swarm optimization （PSO） method, a strategy to optimize the grinding robot structural dimensions and position with respect to the grinding wheel is put forward to obtain the necessary dexterity grinding space. Finally, to grind an aerial engine blade, a dedicated PPPRRR （P： prismatic R： rotary） grinding robot structural dimensions and position with respect to the grinding wheel are optimized using the above strategy. According to simulation results, if the blade is placed within the dexterity grinding space, only one gripper and one grinding machine are needed to grind its complex shaped surfaces.

富钴结壳是一种经济价值高、开发前景好的海洋矿产资源,其外部形态、内部构造和地球化学特征记录了古海洋环境的演变信息。本次研究借助富钴结壳细致分层的显微构造及元素地球化学的差异分析,探讨中太平洋莱恩海山富钴结壳成因及形成过程。富钴结壳样品由上至下可分为5层,顶部较致密Ⅰ层黑褐色,表面光滑,杂质较少,具有雪松状叠层石构造,反映了沉积水动力较强;较致密Ⅱ层与Ⅰ层宏观特征类似,具有柱状和胡萝卜状叠层石构造,沉积水动力最强;疏松Ⅲ层和疏松Ⅳ层黄褐色,内含沉积物杂质,多见斑杂状构造,沉积水动力比较弱;致密Ⅴ层为磷酸盐层,具有亮黑色的沥青光泽,富含有孔虫化石,底部Ⅴ层Sr、P、Ca等元素明显富集,表明了海洋生物的明显参与,沉积水动力最弱。莱恩海山Ce异常及高钴高锰低铁特征,表明结壳长期处于氧化环境;而Mn、Fe、Co等元素地球化学特征综合表明,海洋水动力及氧化性总体表现为由底部Ⅴ层至Ⅱ层氧化性逐渐增强,至顶部Ⅰ层有所减弱的趋势;依据元素分配系数、Ce正异常、Ho正异常、Y负异常及成因三角图,判定结壳为南极底流影响下的海水成因。综合结壳年代学数据,在元素剖面中记录了三期磷酸盐化事件,恢复了莱恩海山富钴结壳的生长过程。

洪水庄组是华北中元古界主力烃源岩之一,生烃潜力巨大,物源和沉积环境存在争议。根据微量元素及碳、氧同位素资料,分析京西坳陷周口店地区洪水庄组地球化学特征,明确物源特征及沉积环境。结果表明:京西坳陷洪水庄组物源具有多源性,陆源贡献主要分布于洪二段和洪三段。洪二段页岩明显富集高场强元素和轻稀土元素,轻、重稀土元素分异严重,反映碎屑物质可能来自华北中元古代岛弧背景下的大陆岛弧长英质物源区。洪一段沉积期,京西坳陷处于半潮湿气候下,盐度相对较高,在弱氧化—弱还原的浅水环境下形成白云岩;洪二段沉积期,气候潮湿,海侵导致京西坳陷海平面上升,碳酸盐岩台地消亡,长英质碎屑搬运至低盐、厌氧、中等分层的深水环境沉积而形成黑色页岩;洪三段沉积期,沉积环境与洪一段的类似,水体环境重新变咸但低于洪一段的,泥质白云岩沉积于弱还原、弱分层水体环境。总体上,周口店地区洪水庄组发育局限浅海相沉积,在潮湿气候的厌氧—缺氧环境下,经历海水由浅变深再变浅的沉积过程,洪二段具备烃源岩发育的最佳地质条件。该结果为京西坳陷洪水庄组古气候及古地理的重建和烃源岩的评价提供地质依据。
