The old Egyptians believed they would come to life again in a thousand years perhaps, after they had died, but they never did. The old Greeks didn\'t think much about coming to life again, but about two thousand years after the old Greek artists had died, people were born in Italy who in many ways were like those old Greeks. Indeed, these Italians were so like the old Greeks that it seemed almost as if the old Greeks had been born again, and were living once more—not in Greece, but in Italy. So we call this time the Born Again time, or by the long name Renaissance.

目前低盐度水驱研究主要集中于中高渗透、高黏土质量浓度的砂岩油藏,是否适用于致密砂岩油藏有待于深入研究.基于这种情况,以鄂尔多斯盆地致密油藏岩心和原油为研究对象,利用岩心驱替实验、润湿角测定实验、界面张力以及界面扩张流变测定实验开展致密砂岩油藏低盐度水驱作用规律研究.实验结果表明:低盐度水驱适用于致密砂岩油藏,调整注入水离子组成改变岩石表面润湿性以及油水相互作用,即可实现采收率的提高;其中,降低Ca2+质量浓度或增加SO42-质量浓度可促进极性原油组分脱离岩石表面,增强岩石表面水湿性;与此同时,降低Ca2+
We\'re all familiar with songs getting stuck in our head while we\'re awake, but it turns out this “earworm” phenomenon can happen during sleep as well. A new study investigating the phenomenon indicates that earworms invading our brains at night coul
As an important part of the power source for high-speed trains, the overhead line equipment itself has strong stability, but there are too many light objects floating along the line. These foreign objects are extremely dynamic and difficult to control. Ex
为了解决稠油黏度大而难开采问题,采用自生热降黏解堵工艺技术,利用化学生热剂和催化水热裂解的协同作用,开采近井地带富含沥青质的稠油.结果表明:优化开发的自生热降黏解堵体系,以浓度为5 mol/L的NaNO2和NH4 Cl为产热剂、质量浓度为10 g/L的硼氢化钠为产氢剂、质量浓度为15 g/L的水热裂解催化剂为添加剂,体系产热温度最高达155℃,有效产气时间为27 min,稠油降黏率为70.1％.自生热降黏剂反应残液对黏土的防膨率稳定在45％以下,对石蜡的溶解度为31.4％,可以有效保护储层的渗透性,解除石
教育部考试中心在2019年11月颁布了《中国高考评价体系》,此次研制的中国高考评价体系由“一核四层四翼”组成:“一核”指立德树人、服务选才、引导教学;“四层”为核心价值、学科素养、关键能力、必备知识;“四翼”为基础性、综合性、应用性、创新性[1].随着经济社会的快速发展,国家对具有创新意识和创新思维能力的要求越来越高.基于此,在命制高考试题过程中也会渗透这种思想,追求试题的创新性,这必然是一个趋势,某种程度上这也是逐步推动高考内容与形式改革的必然方式,对一线教师的教学具有重要的指导意义.本文以数学学科为例
中国共产党自成立之初就以马克思主义的劳动教育观为指导,参与留法勤工俭学活动,开展平民教育运动,使知识分子与工农群众相联系.中国共产党在革命、建设、改革、发展、创新的伟大实践中探索出中国特色的劳动教育道路.在中国共产党百年诞辰之际,回顾和梳理党倡导劳动教育的百年历程,再塑劳动教育新体系,对于新时代开展劳动教育具有重要的意义.
《教育部关于加强初中学业水平考试命题工作的意见(2019 年版)》[1]提出,试题命制一是要考查学生基础知识以及基本技能的掌握情况,二是要检验学生是否具备良好的思维过程、是否拥有创新的意识,以及学生是否掌握了分析和解决问题的能力.2020年福建省中考数学试卷考虑到今年突发疫情对教育方方面面都产生了影响,因此试题素材的选择和试卷难度进行合理选择和科学控制;同时,试卷命制既需要兼具基础性和合格性,又注重创新性、综合性以及应用性.2020年中考第16题主要特点:微探究,微创新,彰素养,促教改.
Coffee is a multibillion dollar industry that supports the economies of several tropical countries. Unfortunately for them, coffee bushes grow best in a rather narrow range of temperatures, so their cultivation is threatened by a changing climate.
选取西安市12所幼儿园的603名幼儿园教师作为研究对象,通过问卷调查法考察幼儿园教师的情绪劳动、职业压力和应对方式状况及三者之间的关系.研究发现,幼儿园教师职业压力及各维度与表层行为均呈显著正相关,与自然行为呈显著负相关;情绪劳动各维度和积极应对方式均呈显著正相关,表层行为与消极应对方式呈显著正相关,自然行为与消极应对方式呈显著负相关;职业压力及其各维度与消极应对方式呈显著正相关,工作难度与挑战性维度与积极应对方式呈显著负相关.工作难度与挑战性、积极应对方式对表层行为具有显著的正向预测作用,积极应对方式对
