, 2014 主流的西方道德责任理论认为,只有当一个行为是我们有意识选择的结果时,我们才对该行为负有责任。这是道德责任讨论中常提到的选择条款(THE VOlITIOn COndITIOn)。哲学家乔治·谢尔形象地称之为“探照灯理论“(THE SEArCHlIgHT VIEW)——我们只对那些在意识聚焦下选择的作为或不作为才负有道德责任。~([1])近年来,不少学者对选择条款提出了质疑,认为这一条款与许多日常的归责实践(尤其是法律实践)相冲突。本文将对这些质疑和其中的缺陷进行分析,并尝试从举证任务(burdEn Of ...

Dianci bileiqi, 1973 焙烧是所有陶瓷工业部门一个最重要的工序,因为焙烧的好与坏对整个生产成果起着决定性的影响。如果在焙烧过程中产生废品,就会使以前投入的劳动和花费的物资付之东流,前功尽弃。瓷器焙烧时一系列复杂的过程,要求我们提出窑炉设备和生产工艺的研究课题。即要求我们准确地作出窑炉相应的车位范围的温度和窑炉气氛的切实规定。即使采用高度工业化的窑炉装备,对于生产废品的认识也是极为复杂的 ...

Zhejiang Daxue xuebao. Lixue ban, 2018 六溴环十二烷是一种使用量较高的溴代阻燃剂，具有持久性、生物富集性、半挥发性和高毒性，可在沉积物、水体、土壤和尘埃以及生物体内广泛检出.目前对土壤中六溴环十二烷的分布及浓度的研究主要集中在电子废弃物拆解地等典型高浓度地，而对工业区、养殖区的研究相对较少.实验采用UPLC-MS/MS法检测工业区、养殖区土壤中六溴环十二烷异构体的分布，旨在探明六溴环十二烷在不同类型环境土壤中的浓度及异构体分布差异，以促进对环境中六溴环十二烷的生态危害性的有效评价.结果显示，六溴环十二烷具有较高的检出率(82.00 ...
