为提高舰炮武器系统作战效率,对舰炮激光制导弹药在典型条件下激光照射指示与跟踪探测进行仿真验证。针对舰炮武器系统激光精确制导弹药使用场景,建立了激光照射指示与弹药探测跟踪模型,编制了激光制导光区仿真计算软件,研究了不同气象能见度条件、不同攻击目标、舰艇本舰照射指示、无人机载照射指示等条件下激光精确制导弹药与照射器间的协同方法及指示、探测能力,并进行仿真计算。得到反射激光能量密度随着角度θ_(c)的增大过程中,反射激光的能量密度在逐渐减小,激光入射角度θ_(z)越大,反射激光的能量密度越大,两种照射方式产生的激光制导光区较为接近。无人机激光制导方式与舰船激光制导方式各有优劣,可适用于不同应用场景。

地震地质 1990年第4期 364-366页

作者： Wang Ji-yang and Huang shao-peng(Institute of Geology, Academia Sinica, Beijing 100029)

During the last 2 years, heat flow data increased significantly in China as a result of implementation of many comprehensive geodynamic (including geothermal) projects and GGT project in China. In this paper, a total of 366 reliable heat flow data is collected from published and in press sources in the Compi-ilation of Heat Flow Data in the China Continental Area (2nd edition). Statistic analysis of these data shows that the heat flow values in China continental area vary from 20 to 140 mWm-2. The mean value appears to be 66 mWm-2.

Gastric cancer(GC), the fifth most common cancer globally, remains the leading cause of cancer deaths worldwide. Inflammation-induced tumorigenesis is the predominant process in GC development;therefore, systematic research in this area should improve understanding of the biological mechanisms that initiate GC development and promote cancer hallmarks. Here, we summarize biological knowledge regarding gastric inflammation-induced tumorigenesis, and characterize the multi-omics data and systems biology methods for investigating GC development. Of note, we highlight pioneering studies in multi-omics data and state-of-the-art network-based algorithms used for dissecting the features of gastric inflammation-induced tumorigenesis, and we propose translational applications in early GC warning biomarkers and precise treatment strategies. This review offers integrative insights for GC research, with the goal of paving the way to novel paradigms for GC precision oncology and prevention.
