详细信息

  • "Solid" 实体包括命名的数学固体,例如封闭的填充三维区域.
  • "Solid" 实体类包括基于几何和拓扑特征的数学分类.
  • 部分属性可用于作为整体的 "Solid" 实体类型,并可用 EntityValue["Solid",property] 格式给出,此类属性包括:
  • "Properties"可用属性列表
    "PropertyCanonicalNames"可用属性的标准名称
    "SampleEntities"可用实体的范例列表(通常长度为 10)
    "SampleEntityClasses"可用实体类的范例列表(通常长度为 10)
    "EntityCount"可用实体的数目
    "Entities"可用实体的列表
    "EntityCanonicalNames"可用实体的标准名称
    "EntityClasses"可用实体类的列表
    "EntityClassCanonicalNames"可用实体类的标准名称
    "PropertyClasses"可用属性分类的列表
    "PropertyClassCanonicalNames"可用属性分类的标准名称
    "PropertyCount"可用属性的数目
  • 以下注释可用于 EntityValue["Solid",property,annotation] 的第三个参数中:
  • "EntityAssociation"实体和实体-属性值的关联
    "PropertyAssociation"属性和实体-属性值的关联
    "EntityPropertyAssociation"此关联中,指定实体是键,值为属性和实体-属性值的嵌套关联
    "PropertyEntityAssociation"此关联中,指定属性是键,值为实体和实体-属性值的嵌套关联
    "Dataset"此数据集,指定实体是键和值为属性名称和实体-属性值的关联
  • 以下注释可用于 EntityValue[property,annotation] 的第二个参数中:
  • "Description"属性的简短文字描述
