刀具磨损监测的随机向量相关度量法

本文提出了一种运用功率累积和与n 维随机向量相关度量监测刀具磨损的新方法,即通过计算刀具三向振动加速度的相关度量系数,主轴扭矩或某项振动加速度的功率累积和综合监测刀具的磨损、破损以及刀具磨损的程度。该法在简单性、可靠性等方面比以往提出的方法有较大的进步,因而使得本方法具有很大的应用前景。文中对该法的理论基础进行了严格的证明,并给出了实验论证结果。

Transformation of Military Ethics During the Zhou Dynasty in Ancient China

ABSTRACT

The transformation of the governance model from a rule of virtue to political realism in China has been a topic of great interest to scholars. In this study, I examine military culture during the Zhou Dynasty and investigate the changes in ethics based on factors such as cultural values, social customs, and political structure to understand the process by which moral values have changed as the governance model transformed from rule of virtue to political realism. I found that military ethics have changed from governance through the use of rituals during the Western Zhou Dynasty to what was called “deception makes an army” during the Eastern Zhou Dynasty.     

Killing with Culture: Anthropology’s Ethical Dilemma with War

ABSTRACT

This article highlights the difficulty of creating a code of ethics in anthropology, particularly one that appropriately addresses the nuanced nature of the military and the anthropologists who conduct research and disseminate information in the context of war. The article consults one of the most important books on this topic, George R. Lucas' Anthropologists in Arms (2009), along with several other relevant texts, and examines the ethical complexities and dilemmas American and European anthropologists faced during their involvement in both World Wars, as well as those faced during Vietnam and the more recent wars in Iraq and Afghanistan. The article also examines the military's recruitment of cultural experts, the methods used to culturally engage combatants, and the criticisms against social scientists who choose to work as so-called military anthropologists. The anthropologists in this article risked academic exile conducting what some consider an adulteration of academic principles. The article contributes to the discourse regarding unconventional warfare and the methods used by the armed forces to better understand the cultural nuances of people, and to highlight the need for the development of a better anthropological code of ethics that accounts for the challenges of war.
