Measurement of conversion efficiency of soft X-ray from 0.35μm laser-irradiated aluminum planar targets

Conversion efficiency of soft X-ray from 0.35 μm pulse laser-irradiated aluminium planar target at laser intensities 10¹³–10¹⁵ W/cm² on the Xingguang-II facility (laser energy 5–90 J, focal spot ⊃ Ф 200 μm full width of half maximun (FWHM) 400–800 ps) was measured. A simple model was given to explain soft X-ray conversion efficiency. In this model, because of the heat conduction from the laser-heated spot, the conversion was very small at lower irradiance limit, while at higher limit it was bounded by the energy lost in blow off plasma. Consequently, at the laser intensity around 2×10¹⁴ W/cm², the X-ray conversion efficiency reaches a maximum.

“看好自家门儿，适当串串门儿”——谈“3＋X”高考化学复习方略

理科综合首先是学科内综合，其次才是跨学科综合。因此，在高考化学复习中，要在立足本学科内容复习的基础上，再适当关注学科间相关内容的复习。     

基于“1+X”证书制度的活页式教材开发与设计

“1+X”证书制度与活页式教材是我国职业教育当下和未来的重点建设方向,两者融合的教材可称为“课证”活页式教材。企业任务导向和职业技能等级标准既是“课证”活页式教材的重要特征也是其开发与设计的关键,以新能源汽车专业为例,提供了“课证”活页教材开发设计流程和基本思路,并强调了建立动态评价和反馈机制的重要性。
