| The mental health movement in the
United States began with a period of considerable enlightenment. Dorothea Dix
was shocked to find the mentally ill in jails and almshouses and crusaded for
the establishment of asylums in which people could receive human care in
hospital-like environments and treatment which might help restore them to
sanity. By the mid 1800s, 20 states had established asylums, but during the late
1800s and early 1900s, in the face of economic depression, legislatures were
unable to appropriate sufficient funds for decent care. Asylums became
overcrowded and prison-like. Additionally, patients were more resistant to
treatment than the pioneers in the mental health field had anticipated, and
security and restraint were needed to protect .patients and others. Mental

A. 垄断的反面是完全竞争，而要形成完全竞争，必须至少要有两家以上企业生产和销售同种商品或可有效替代的商品 B. 垄断商品的替代物必须尽可能有效，虽然替代物的概念比较模糊，但如果根据实际情况分析也能判断出来 C. 入行壁垒的坚固是保持有效垄断的必需，当技术发展；原先的壁垒降低时，企业的垄断地位可能将受到挑战 D. 动摇垄断者的地位，可以由国家采取强制措施，将该企业强行分为两个以上企业，也可以通过提高技术或发展科学来降低壁垒或找到替代物等 [多选题]隔离开关红外测温检测范围包括：引线、（）、二次回路。
