生态营区水环境系统规划研究

水环境系统规划作为一项主要技术措施,在生态营区建设中具有重要地位。文章分析了水环境系统规划的核心思想,并从建筑给排水、雨水回收与利用、废污水处理与中水利用、绿化与景观用水四个方面探讨了水环境系统规划的主要内容,可作为生态营区水环境建设的参考。

矿业城市概论

本文对矿业城市给出明确的定义和定量标准。矿业城市有有依托和无依托两类成因，“蚕茧”和“蝌蚪”两种消亡方式。必须从青年期就开始进行产业结构调整。努力探索适应本地区情况的发展道路，在不宜建设城镇的地方提倡用“采矿营地”方式开采矿产资源。同时还讨论了矿业城市资源枯竭问题。     

中国特色的汽车露营公园建设——以北京国际汽车露营公园为例

房车旅游作为生态旅游的一种,在国外已经发展了数十年,成为人们休闲旅游的一部分,而中国的房车旅游还是新兴事物,处于起步阶段。因此,在国外已较为成熟且普及的房车营地旅游成为了中国现阶段大有发展前景的特色旅游形式,建设中国特色的房车旅游营地,是这一特色旅游形式大力发展的必要手段,北京国际汽车露营公园是中国目前较为完善且获得欧洲四星标准认证的露营公园,本文以此为例,探讨其开发与建设模式,为中国特色的汽车露营公园建设提出方向,开拓中国的特色休闲旅游领域。     

Flame propagation in a tent camp

This paper presents an experimental study leading to the understanding and modelling of the effect of air speed and its direction on flame propagation in tent fabrics in addition to fire propagation in a tent camp. The study was conducted on burning fabrics of different densities subjected to wind speeds ranging between zero (stagnant) and 1.4 m s^?1. Moreover, several air directions with respect to the flame were considered in the study to cover the cases of vertically upward, downward, horizontally aiding and opposing, and inclined directions. These cases were used in simulating actual flame propagation in a tent. It is found that there is a logarithmic relation between the time of burning a tent and air speed and the density of tent fabrics. Two different types of fabric are considered; waterproof and non‐waterproof. It is also observed that the surface flame temperature is invariant with air speed or fabric density and it reaches about 650°C. The results show that denser fabrics require more time for burning. The maximum flame propagation speed is observed for vertically upward flame concurrent with air direction. On the other hand, minimum flame propagation is observed for vertically downward flames opposing the air direction. A model is derived for predicting the time required for flame propagation in a known camp area. Copyright © 2001 John Wiley & Sons, Ltd.     

基于Rough集理论的营区规划综合评价

随着社会经济的发展,军用土地资源的重要性越来越为人们所重视,土地资源的规划直接影响土地资源的管理,因此,对军用土地资源规划管理的研究受到了广泛的重视,是目前研究的重点之一。军队营区规划涉及方方面面,文章首先建立营区规划评价指标体系,并运用Rough集理论对营区性能进行综合评价,为营区规划评价提出了新的方法。     

Multimodal Homesickness Prevention in Boys Spending 2 Weeks at a Residential Summer Camp.

Homesickness is the distress or impairment caused by an actual or anticipated separation from home. It is characterized by preoccupying thoughts of home and attachment objects. In its severe form, homesickness is subjectively distressing and has clinically significant cognitive, emotional, and behavioral sequelae. This study provided 75 boys who ranged in age from 8 to 16 years and who were 1st-year campers at an overnight summer camp with an inexpensive, multimodal homesickness prevention package. Results suggest that combining environmental information, psychoeducation, social support, explicit coping instruction, caregiver education, practice time away from home, and surrogate caregiver training can reduce homesickness and associated behavior problems. These data support the theory that novelty reduction, attitudinal shifts, preseparation coping enhancement, and supportive social environments diminish the negative emotional intensity of homesickness.

转录因子MSN2基因过表达对酿酒酵母耐受性的影响

cAMP信号通路在调控酵母细胞代谢、增殖、分化及压力抗性的获得过程中具有重要的作用。工业应用中对酵母的耐受性有很高的要求,在发酵过程中,胁迫环境如高温、高渗透压、营养饥饿和高浓度酒精毒性等不可避免,故而提高酵母菌种的耐受性,可以提高菌种的发酵性能,降低发酵过程中的能量消耗。本文构建的突变株在工业应用方面具有重要的意义。以实验室现有菌种AY12a为出发菌株,URA3基因作筛选标记,利用胞内重组,在MSN2基因的N端加上强启动子PGK1_p以实现基因的过表达,最终通过PCR验证,成功构建突变株AY12a-msn2。对酵母进行耐受性的测定,发现AY12a-msn2不具有一定的耐高温性能。同时将突变株与AY12a进行玉米高温浓醪发酵,并测定发酵完成后的酒度、残糖、48 h细胞存活率、CO_2失重及发酵时间。结果发现突变株AY12a-msn2酒度下降,残糖含量上升,48 h细胞存活率上升,发酵时间较长。
