自2014年新高考改革启动以来,已在全国29个省市逐步推进。调研发现,新高考在实际推进中给普通高中传统的教育、教学和管理带来了诸多压力与挑战,这突出表现为:“选课走班制”在实际推行中存在许多堵点;“学生综合素质评价”面临着评价标准不一、结果应用受限等困境;“学生生涯规划教育”存在着专业性不强、效果不佳等问题;学生多样化自由选课凸显教师队伍结构性缺编等。针对上述问题,应加强普通高中选课走班制的资源条件支持,健全学生综合素质评价的体制机制,提高学生生涯规划教育的专业性和精准度,积极破解改革所导致的教师结构性缺编问题,以推动和确保新高考改革各项政策有效落地实施。

Science China Chemistry 2020年第7期63卷 875-880页

作者： yong-Jie Wu Qi-Jun Yao hao-Ming Chen gang Liao Bing-Feng Shi Department of Chemistry Zhejiang University Hangzhou 310027China School of Chemical&Environmental Engineering Wuyi UniversityJiangmen 529020China

A strategy for Pd-catalyzed ortho-C–H silylation of biaryl aldehydes enabled by a transient auxiliary is presented. This protocol provides a broad range of ortho-silylated biaryl aldehydes in good yields. The silyl moiety can be further functionalized under mild conditions, rendering the silylated products useful building blocks. Notably, this protocol also offers an opportunity to establish a platform for expeditious synthesis of structurally diverse axially chiral biaryl aldehydes via sequential atroposelective interannular C–H functionalization/intraanular C–H silylation.

以蒸发量为670t/h的四角切圆布置煤粉锅炉为研究对象,在不同燃烧器高宽比下,模拟了燃烧器平面温度场、射流中心两侧静压差。燃烧器高宽比大于9时,炉内气流切圆直径达到最大,高温区域均到达壁面附近,易引起结渣或高温腐蚀等;在4～9时,气流切圆大小适中,燃烧组织合理;小于4时,炉内气流充满程度相对较差,炉膛中部火焰过于集中,不能发挥切圆燃烧组织的优势。燃烧器出口射流两侧静压差随着燃烧器高宽比的增大呈非线性增大。

目的:通过回顾性病例对照研究分析外伤性脑出血术后非手术区再出血的危险因素。方法:收集外伤性脑出血患者240例,根据是否发生术后非手术区再出血分为再出血组57例和未出血组183例。对2组患者的临床资料进行统计学分析。结果:2组单因素资料比较,前白蛋白、Glasgow昏迷评分(GCS)、血肿量、白细胞计数、血糖、发病到手术间隔时间及中线移位差异有统计学意义(P<0.05)。多因素Logistic分析显示GCS、血糖及发病到手术间隔时间是非手术区再出血的独立危险因素,ROC曲线分析显示三者在一定程度上可预测外伤性脑出血术后非手术区再出血。结论:外伤性脑出血患者GCS评分低、血糖水平高及发病到手术间隔时间短,术后合并非手术区再出血的风险大。
