当前职业(技工)院校焊接技能人才培养实施的是“广而宽”教育,缺少“针对性”与“适用性”,与社会发展有所脱节。文中基于企业对数字化焊接技能人才实际需求,围绕数字化焊接专业学生就业岗位群,剖析满足岗位所需的知识能力、实操能力、职业素养等一系列职业能力特征,对职业院校焊接专业现有教学内容与课程进行梳理与重置,从企业、学校、学生3个视角共同构建基于数字化技术的焊接技能人才职业能力标准、课程体系与教学内容,力求做到贴近实际需求、便于开展教学、易于学生接受。 相似文献

The possibility of using unique properties of lanthanides in the nanotechnology is demonstrated. The origination of linear
and nonlinear optical properties of lanthanide compounds with phthalocyanines, porphyrins, naphthalocyanines, and their analogs
in solutions and condensed state and the prospects of obtaining novel materials on their basis are discussed. Based on the
electronic structure and properties of lanthanides and their compounds, namely, optical and magnetic characteristics, electronic
and ionic conductivity, and fluctuating valence, molecular engines are classified. High-speed storage engines or memory storage
engines; photoconversion molecular engines based on Ln(II) and Ln(III); electrochemical molecular engines involving silicate
and phosphate glasses; molecular engines whose operation is based on insulatorsemiconductor, semiconductor-metal, and metal-superconductor
types of conductivity phase transitions; solid electrolyte molecular engines; and miniaturized molecular engines for medical
analysis are distinguished. It is shown that thermodynamically stable nanoparticles of Ln

composition can be formed by d elements of the second halves of the series, i.e., those arranged after M = Mn, Tc, and Re.
Prospects of using lanthanide superconductors in nanotechnology are considered. 相似文献
