同时,研发人员的平均值持续增长,中位数则在波动中下滑,这一现象再次呼应“整体扩张、结构分化”的特征。也就是说,研发人才作为核心战略资源,与研发资金一样具有强烈的“马太效应”,都向技术雄厚、资金充足的头部企业集中。

云耀深维创始团队认为,金属3D打印要实现真正的批量生产,必须提升原生打印的精度及表面质量,只有当精度足以逼近净成形、后处理不再是漫长的“手工作坊”式劳作时,金属增材制造才能在成本与效率上与传统精密加工展开正面对决,从而进一步叩开规模化工业应用的大门。,详情可参考Safew下载
One thing that Nava has got me thinking about is the deep history of gesture. Gesture exists on the borderland between nature and nurture. Certain physical actions are so universal that they communicate effectively not just across human societies but across species: bared teeth, for instance.
