塞奇（Secchi，Pietro Angelo，1818—1878）梵蒂冈天文学家（Astronomer,Vatican）

塞奇1833年进入耶稣会，继而当了一名天文学家。他很早就掌握了一些新技术。他与哈金斯同时首先系统地将分光技术运用到天文学上来，并首先作了光谱巡天工作，从1864年到1868年研究了4000颗恒星的光谱。这就很清楚地看出了恒星光谱彼此之间是各有不同的，于是，在人类历史上第一次发现了不同恒星之间除了在位置、亮度和颜色这几个方面以外，还有着化学组成的不同。塞奇首先将照相的新技术用于天文事业。     

人类的内在科学——珠心算

一、前言人类的头脑从出生到死亡离不了数字,从启智到失智也离不开数字,加减可以增加宽度,乘除可以增加推理判断及应用能力,如果没有数字,就不可能正确的看、听和表现,而表现的基础上,能够形成比较、判断能力,要头脑更聪明必先有数字反应能力。

两个“九九歌”应该逐步“统一”

“九九乘法口诀”,一般简称“九九歌”,是我们中华民族的伟大创造。这一创造,对计算数学的实施提供了极为便捷的条件．是人类文明史上的重要内容,也是我国在数学领域的一项非物质文化遗产。“九九歌”从创始至今。大约已有三千多年的历史了。由于流传时间跨度长。其整体结构、内容繁简,乃至选字用句难免略有变化。概而言之．这变化的结果最终使人们的认识形成两大派,久久不能统一．今特略作分析并提出本人的看法：     

机器学习在新材料筛选方面的应用进展

新材料产业是许多相关领域技术变革的基础,也是新能源、航空航天、电子信息等高新技术产业发展的先导.传统研发手段由于成本高、效率低、商业化周期长等不利因素无法满足现代社会的发展需求.近年来大数据与人工智能不断深入结合,以数据驱动为核心的机器学习在新材料设计、筛选以及性能预测等方面取得巨大进展,极大促进了新材料的研发与应用.本综述总结了机器学习的基本过程及其在材料科学中常用的算法和相关材料数据库,重点介绍了机器学习在不同功能上的应用以及在催化剂材料、锂离子电池、半导体材料和合金材料等领域的性能预测和材料开发中的最新进展,并对其下一步在新材料应用方面提出展望.     

“生活教育”在物理教学中的应用

生活即教育"是陶行知生活教育理论的核心,它明确指出了生活决定教育,教育以生活为中心的思想。它包括三层涵义:生活教育是人类社会所固有的,生活便是教育;生活教育伴随人类生活产生变化;生活决定教育,实践生活是教育的中心。因此,教育的内容应是为生活所必需的,教育应在生

TILLING技术的最新进展及其在辐射诱变育种中的应用前景

定向诱导基因组局部突变技术(Targeting Induced Local Lesions IN Genomes, 简称TILLINC)是一种全新的、高通量和低成本反向遗传学研究方法。近年来, 随着突变筛选技术的革新, TILLING技术平台日趋多元化, 使得TILLING技术的操作更为简单﹑快速, 并广泛应用于作物育种研究领域。简要介绍了TILLING技术平台的最新发展动态, 并初步探讨了将辐射诱变处理与TILLING高通量筛选相结合在诱变育种中的应用前景。To investigate the M1 biological effects of heavy ions irradiation on Lycopersicon esculentum Mill., its seeds were irradiated by 12C6+heavy ions (80 MeV/u) with the dosages of 30, 60, 90, 120 and 160 Gy respectively . The results showed that with doses increased gradually, germination rate and seedling rate of Lycopersicon esculentum Mill. were decreased, and the latter was lower than the former, mainly due to the inhibition of root growth. The irradiation increased the content of MDA and proline evidently, showing irradiation could damage biomembrane, and also decreased the activities of POD and SOD with distinct inhibition pattern. However, the low dose and high dose irradiation promoted APX activity, illustrating APX was induced to protect irradiation injury. In brief, exposure to 12C6+ heavy ions had obvious injury effects on the seeds of Lycopersicon esculentum Mill.. Heavy ions irradiation damaged biomembrane, inhibited activities of enzymes, and finally inhibited the growth of the first generation of these seeds.     

Numerical simulation of micro-particle deposition in a realistic human upper respiratory tract model during transient breathing cycle

An more reliable human upper respiratory tract model that consisted of an oropharynx and four generations of asymmetric tracheo-bronchial (TB) airways has been constructed to investigate the micro-particle deposition pattern and mass distribution in five lobes under steady inspiratory condition in former work by Huang and Zhang (2011). In the present work, transient airflow patterns and particle deposition during both inspiratory and expiratory processes were numerically simulated in the realistic human upper respiratory tract model with 14 cartilaginous rings (CRs) in the tracheal tube. The present model was validated under steady inspiratory flow rates by comparing current results with the theoretical models and published experimental data. The transient deposition fraction was found to strongly depend on breathing flow rate and particle diameter but slightly on turbulence intensity. Particles were mainly distributed in the high axial speed zones and traveled basically following the secondary flow. “Hot spots” of deposition were found in the lower portion of mouth cavity and posterior wall of pharynx/larynx during inspiration, but transferred to upper portion of mouth and interior wall of pharynx/larynx during expiration. The deposition fraction in the trachea during expiration was found to be much higher than that during inspiration because of the stronger secondary flow.
