主动反射面是FASTfFive-hundred-meter Aperture Spherical radio Telescope)望远镜的一个重大创新之一,其性能将直接关系到整个望远镜的性能,因此主动反射面的控制需要一个实时高效的控制系统.基于EPICSfExperimental Physics and Industrial Control System)的输入输出控制器(Input/Output Controller,IOC)框架,充分利用EPICS的实时性,根据FAST反射面的控制节点达2000多个的特点设计了新的记录类型-节点控制器记录,以便于控制器节点IOC的管理以及提高代码的复用,并针对FAST主动反射面密云模型对实际装置进行了仿真、设计和部分测试.

我国古代把掌管文字记录的专职人员通称为"史".甲骨文的"史"字为右手持物的人,至于所持为何物,则有许多不同的解释,或说是简策,或说是盛策之器,也有认为是笔.总之,这些解释尽管有异,但有一个共同点,便是都与文字和图书有关.王国维说"史"是专门保管、研究及写作的官吏,它的另一个名称是"作册",负责起草册命和记录宫廷中的重要事件、天子诸侯的言行和政府各机构的种种活动.

Lesser kestrels Falco naumanni are migratory central-place foragers that breed in dynamic arable landscapes. After arriving from migration, kestrels have no knowledge of the distribution of crops, and consequently prey, around their colony. The energy demand of pairs increases as breeding season progresses, but at the same time prey abundance, and their knowledge on prey distribution, also increases. Wind can have a strong influence on flight cost and kestrels should try to reduce energy expendi- ture when possible. When prey abundance is low, kestrels have little knowledge of prey distribution, and pairs have no chicks, they could reduce foraging flight cost by leaving the colony with tailwinds. When prey is abundant, knowledge on prey distribu- tion has increased, and chick demand is high, kestrels should fly to the most favorable foraging patches. We analyzed foraging trips directions in a lesser kestrel colony along the breeding season and in relation to wind speed and direction. We recorded 664 foraging trips from 19 individuals using GPS-dataloggers. We found that outward flights direction changed from uniform to a concentrated distribution along the season, as prey abundance and individual experience increased. We also found a temporal trend in the angular difference between outward flights and wind directions, with low values early in the season and then increa- sing as expected, but again low values at the end, contrary to expectation. Results suggest changes in kestrels foraging strategy along the season in relation to wind. Kestrels depart more with tailwinds in exploratory flights early in the season, while there is a spurious coincidence in direction to preferred foraging patches and dominant wind direction at the end [Current Zoology 60 (5): 604-615, 2014].
