从文化视界看高等学校学报的价值

高等学校学报的价值研究,对于提高学报自身的知名度,进一步发挥其职能作用,具有重要意义。本文对高校学报的价值问题作了整合梳理研究,重新审视和评价了学报的地位。从文化视野中的九个方面概括和论证了高等学校学报的价值。

略论写作教学中存在的三个问题

学生写作能力提高缓慢,是长期困扰写作课教学的一大难题。究其原因在“教”与“学”,由知识向能力的转化过程中,存在着若干薄弱环节。重视写作理论、写作技巧的传授,忽视积累储存的要求,难以奠定扎实的“物质”基础;忽视评析能力的培养和训练,导致学生品鉴、评析能力低下;忽视修改过程,缺乏及时得当的点拨,习作难以达到预期效果。要想有效地提高写作能力,就要切实加强这几个环节。

Storage and Subsequent Reactivation of Phosphate-Accumulating Aerobic Granules

Phosphate-accumulating aerobic granules cultivated in a sequencing batch reactor were composed of inner rod-shaped bacteria aggregates and outer twining filamentous bacteria. The influence of two-month storage under dif- ferent conditions on the storage and subsequent reactivation performance of aerobic granules was investigated. After two-month storage the granules sealed at 4 ~C in distilled water or normal saline （named granules A and granules B, respectively） could maintain their characteristics as before, while the granules idled in the reactor at room temperature （named granules C） exhibited decreased properties. During reactivation, granules A and granules B presented almost identical recovery performance, faster than granules C, in terms of phosphorus removal efficiency, mixed liquor sus- pended solids （MLSS）, phosphate release and accumulating ability. The results suggest that hermetical storage at low temperature promoted the maintenance of the granular properties and the reviving behaviors of phosphateaccumulating aerobic granules, and storage medium had little influence on the storage and recovery perfomlance.

影像所延伸的人文世界

文字的发明开辟了人类历史的新纪元,它把一代又一代的传说和智慧的积累储存在简单便捷的“划痕”之中,人类前进演化的踪迹便成了折迭起来的存在,人生活在充分人文化的世界。而影像的种种浓缩世界和复印世界的方式将再一次改变人类新的智慧资源和创造环境。
