Cutting behavior exerts a considerable influence on the fabrication of bulk metallic glass(BMG) components. In this study,the influences of machining parameters(i.e.,depth of cutting,feed rate,and spindle rate) on the turned surface of a Zr-based BMG after observing the 3D morphologies of this surface were characterized.The results showed that the influence of the spindle rate on the surface morphologies is more substantial as compared to the depth of cutting and the feed rate. Nanoscratch tests were conducted to further characterize the separation mechanism of the chips,which revealed that the chips are torn off the surface of a BMG because of inhomogeneous localized maximum shear stress.

我和胡震国认识快四十年了。他曾任上海工艺美术职业学院美术系主任，其水墨风景画近年来引人注目。 他原来是画油画的，作品多次入选全国美展和全军美展，美术评论家卢金德先生对他的评价是：“胡震国的油画色调就是法国印象色彩与中国江南湖光深情的融合。” 四十年前，我们一群二十不到的年轻人被分配到皖南工作，第一次见到他，便受感染，他喜欢哲学。佛陀。老庄。家具简单，但四壁不是塞尚、梵高，就是徐悲鸿、齐白石……

20世纪前20年,俄国社会矛盾重重,封建统治政权受到了严峻挑战。作为俄国最高行政执行机关的大臣会议,此时的活动对俄国政治、经济和社会生活等方面起着不容忽视的作用。大臣会议主席作为政府首脑,对大臣会议的各项活动发挥着主导作用。从1905年大臣会议体制改革到1917年大臣会议被临时政府取代的近十二年时间里,П.А.斯托雷平成为担任大臣会议主席（1906-1911年）时间最长的政府领导人。主政期间,斯托雷平提出了土地改革、国家行政体制改革等多项改革主张,这些改革对当时的俄国社会产生了深远的影响。斯托雷平和大臣会
