Flume Experiment on Stream Blockage by the Debris Flow From Tributary

Stream blockage by the debris flow from tributary valleys is a common phenomenon in mountainous area,which takes place when large quantities of sediment transported by debris flow reaches a river channel causing its complete or partial blockage.The dam formed by debris flow may causes upstream and downstream flooding,and presents great threat to people and property.Because of the catastrophic influence on people and property,debris-flow dam has attracted many attentions from the researchers and local administration.But,lit- tle attention has been given to the quantitative interrelationships of the potential influential factors.In this pa- per,the interrelationships of important influential factors caused the stream blockage by debris flow were ana- lyzed through flume experiment,and a model to predict the blockage was presented.     

蒸汽爆炸粗混合阶段冷液中高温球传热阻力耦合特性的实验研究

采用蒸发电力模型,设计了高温颗粒同水相互作用的实验装置,进行了一系列单个,多个粒子在不同温度,不同入水初速度和不同冷液过冷度情况下的系列阻力实验,初步实验分析表明,高温颗粒在刚刚穿过冷液表面的下沉速度明显低于冷态颗粒的速度,实验值与蒸发曳力模型计算值符合较好.     

STD总线多功能CPU板的设计

ＳＴＤ总线工业控制机目前在工业现场中应用极为普遍，但所利用的ＣＰＵ板的功能却比较单一，不能单独形成系统，本文介绍一种ＳＴＤ总线多功能ＣＰＵ板的功能和电路设计．     

基于CAN总线的无功功率补偿系统的数据采集

针对所构建的基于CAN总线的无功功率动态补偿系统,以80C196单片机和SJA1000CAN控制器为核心,开发出无功功率动态补偿数据采集子系统。该系统借助传感器和单片机可实现三相电压、电流等信号的采集、解算,通过CAN总线实现数据的传输。     

Are Reviews an Alternative to Pair Programming?

From the first presentation of extreme programming on, pair programming has attracted a wide range of programmers to work together in front of one display. The proposed advantages of pair programming are a faster development cycle and code with higher quality. However, the nearly doubled personnel cost when compared to single developers seems to outweigh these advantages. Instead of showing the superiority of pair programming, we seek an alternative. Can a single developer be assisted by an already known technique with which he produces the quality of pairs with only a fraction of the cost? The answer with some restrictions is: yes, he can. Reviews are a reasonable candidate with respect to code quality and cost.     

迷宫堰频率群分析

本文应用有限元方法对迷宫堰的振动特性进行分析 ,发现迷宫堰整体模型中出现了频率群的现象。从工程实用角度出发 ,我们由迷宫堰单宫的频率值和单片堰墙模态相似推出整体模型有限元计算结果中频率群的每群个数 ,并且取频率群的均值作为代表值。通过与水弹实验数据的对比 ,认为该代表值在结构的低阶频率区域是可用的。
