Abstract: Cryonics is a product of the modern technological civilization， and in the combination of modern technological rationality and “future study” emotion， death and technology have acquired a more complex coupling. Death technicalization originally refers to the conversion of death from a natural state to a state that depends on technology in the modern technological civilization. Cryonics embodies an attempt of the modern technology to regulate and control death， which is a “post-death” technicalization act in nature. Faced with the ethical dilemma of life and death caused by cryonics， it is necessary to take modern bioethics as the basic principle for conducts and to clarify the point that medical assistance is more significant than medical experiments in terms of technical operation. Moreover， death is still a spiritual event and means the transformation of the legal and ethical relationships of the dead in terms of legal rights and ethics. Only in this way will the ambiguity of life and death in biotechnology not evolve into a social ethical issue， and the technical operation itself can be stipulated based on ethical rules.
