一扣一滋味

作为传统糕饼制作模具,"龟印"逐渐被机器取代。虽然机器模具也能做出香甜可口的糕饼,但总是缺少一股不可替代的人文情怀……厦门中山路局口街街口矗立着3座大红的龟印雕塑,初来乍到的游客常被它喜庆的颜色以及独特的外表吸引,不时有人拍照留念。雕塑的原型是厦门独有的民间艺术——龟印,这是制作红龟棵必不可少的工具,它曾经占据着闽南地区的大街小巷,为百姓家中常备之物。时至今日,购龟印做红龟糅的人越来越少,手拿龟印一扣一个红龟粿的乐趣已然成为儿时的记忆。但在潘海员眼中,这样的雕塑背后充满酸楚。作为潘氏龟印技艺的传承人,潘海员忠诚地守护着祖上传下的龟印制作手艺,一走就是30多载。

一沙一世界 一水一天堂

<正>旅行,一直是我的最爱,走在路上,感受的不仅是景色的优美、人文的印记,更要有心灵的震憾。你知道吗?世界上还真有那么安静的地方,没有城市的喧嚣,没有涌动的车流,更没有热闹的人群,这就是巴丹吉林,号称人间最美的沙漠,因为她有水的陪伴,沙与水的交溶,动与静的唯美画面,只有来到这里,才能感受到视觉的冲撞,去了才能够真真切切感受得到那里的山、那里的     

一人 一琴 一村

<正>梭罗曾说:"如果我真的对云说话,你千万不要见怪。城市是一个几百万人一起孤独生活的地方。"在福建,有这样一群城市孤独者,从厦门移居至长泰,在后坊村建起了"龙人古琴文化村"他们栖居于天柱山下、马洋溪边,每日于古樟荫绿处斫琴、抚琴,在琴声中追寻理想的生活,实现自我的认同。弃商从艺做琴人斫,砍削之意。古琴选材和斫制有严格要求,斫制一张好琴不易,想成为斫琴师更是难上加难。

A SIMULATION OF A MOTIONLESS MIXER

Continuous laminar mixing in segmented twisted-tape motionless mixers is considered. A solution to the steady isothermal creeping flow of a Newtonian fluid in a twisted-tape mixer has been obtained via two-dimensional numerical procedures. The developed flow within a section of the mixer has been solved in a helical coordinate system by an iterative scheme. The resulting solution is rigorously correct in the absence of entrance and exit flows at the junction between sections. An algorithm is presented for the modelling of these junction flows via two-dimensional procedures. Simulated cross-sectional mixing patterns have been generated for comparison with experimental results

The performance of twisted-tape mixers is simulated for various designs, beginning with the particular geometry of the Kcnics Static Mixer, and for different operating conditions Results suggest that the rate of mixing as a function of the total twist per section is optimized with respect to pressure drop when sections contain 80 degrees of twist. The capability for rational improvement in other design and operating parameters is illustrated. The mechanisms of laminar mixing are discussed and quantified; of primary importance is the tendency for interfacial area to assume an orientation within each section which is favorable to mixing in subsequent sections.     

A MATHEMATICAL ANALYSIS OF A MEMBRANE BIOREACTOR CONTAINING A SLUDGE DISINTEGRATION SYSTEM

The activated sludge process is widely used to treat domestic and industrial wastewater. A significant drawback of this process is the production of “sludge”, the disposal of which can comprise a significant proportion of the total operating costs of a wastewater treatment plant. We analyze the steady-state operation of a membrane bioreactor system (MBR) incorporating a sludge disintegration unit (SDU) to reduce sludge production. We provide a qualitative understanding of the model by finding analytically the steady-state solutions of the model and determining its stability as a function of the residence time. In practice a target value of the mixed liquor suspended solids (MLSS) content within the membrane reactor is specified. Applying the mathematical technique of singularity theory we show that if the sludge disintegration factor is sufficiently high then the MLSS content is guaranteed to be below the target value. This model prediction, of key interest from a practical perspective, was not identified in the original investigation of this model, which relied upon numerical integration of the governing equations.

一种新型传动结构的斜坡辊道

浮法玻璃厂联合车间受工艺限制,往往将2楼熔制成形车间和1楼包装车间用斜坡辊道连接起来。而2楼与斜坡之间衔接的凸弧辊道、1楼与斜坡之间衔接的凹弧辊道,其结构形式往往成为设计及安装调试的难点。传统的弧段结构采用锥齿轮箱和同步带传动结构,与当前主流的通轴弧齿锥齿轮结构相比较为落后。本文对浮法玻璃车间斜坡辊道结构进行详细阐述,并提出了一种新的凸、凹弧辊道的传动结构。
