Fossil Rotifers and the Early Colonization of an Antarctic Lake

Early Holocene sediments from a continental Antarctic lake (Ace Lake, Vestfold Hills, East Antarctica) contained abundant fossil rotifers of the genus Notholca. The fossil is similar to specimens of Notholca sp. present in modern-day Ace Lake and other fresh and brackish lakes of the Vestfold Hills. Cyanobacteria and protists (chrysophyte cysts, dinoflagellate cysts, and rhizopod tests) were also recovered from the core samples. These sediments were deposited early in the freshwater phase of Ace Lake, soon after deglaciation of the area. The occurrence of this trophically diverse assemblage of organisms at an early stage in the evolution of the lake suggests either that they were part of an endemic Antarctic flora and fauna which pre-dated the last glacial maximum and survived in glacial refugia or that efficient intercontinental dispersal had occurred.

CT球管耙心偏移的检测与判断

ＣＴ球管耙偏移是较为少见的，本文以ＧＥ ｓｙｔｅｃ ２０００ｉ为例，详细描述了由此引起的扫描停止，机器伪影等现象及分析、处理过程，并通过与管衰老相比较。进一步述了两者的共同点及在图像质量，管电流稳定性，检测过程等方面的区别，最后总结出一套检测与判断耙心偏移的方法。
