断裂的

TROMSOE, Norway - An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs this month after the collapse of an ice bridge widely blamed on global warming, a scientist said Tuesday.

一位科学家周二指出，一块大如纽约市面积的南极冰棚，本月在一段冰桥塌陷后，崩裂成一座座冰山。许多人将冰桥断裂归咎於全球暖化。

Icebergs afloat today are made of snowflakes that have fallen over long ages of time.

The analytical results show that the neotectonic activities resulted from the nearly north-south-trending compressional stress in the region. Based on previous research results, the neotectonic activities in this area can be divided into five evolution stages: late Eocene to Oligocene, Miocene, late Pliocene to early Pleistocene, early Pleistocene to Mid-Pleistocene, and Mid-Pleistocene to now.

研究表明，新构造以断裂构造为主，是区域近南北向挤压应力作用的结果；结合前人研究成果，可以将伊犁盆地新构造运动分为五期：始新世晚期－渐新世、中新世、上新世末期－早更新世、早更新世－中更新世、中更新世至今。

另一方面，五螺箍RC柱於塑铰区发挥良好之韧性，五螺箍所围束之混凝土大致保持完好，混凝土保护层并无严重剥落之情形，且主筋亦无明显的挫屈现象，箍筋亦未发生断裂。

The morphological analysis and chemical characterization of the worn surfaces via scanning electron microscopy, laser scanning microscope, and X-ray photoelectron spectroscopy reveal that under titrimetric water lubrication, the hBN in Si3N4-hBN spalled off during the wearing tests and the spalled pits formed on the wearing surface of Si3N4-hBN, and then the debris dropped into the pits to react with water, thus a tribochemical film formed on the wearing surface. The formation of the tribochemical film facilitated smoothing the surfaces of Si3N4-hBN and Si3N4 to create a fine lubrication environment.

在滴定法水润滑条件下，磨屑不易被水带走，当Si3N4-hBN与Si3N4配副摩擦时，由于Si3N4-hBN摩擦面上hBN偏聚区域发生脆性断裂和剥落而形成剥落坑，磨屑在剥落坑中堆积并氧化、水解，反应产物富集于剥落坑中，进而在摩擦表面形成含B2O3和SiO2的摩擦化学反应膜，从而保护了Si3N4-hBN和Si3N4摩擦面，使其变得光滑，为发生流体润滑提供了条件。
