毫微过滤和电渗析联合法处理纸浆漂白废水

采用毫微过滤（nanofiltration）和电渗析相结合的方法，一台0．5m3/h地装置可脱除95％污染的有毒的有机卤化物、有毒的有机化合物、盐类和色素，水可重复利用。而普通的生物处理法仅能减少氯化有机物质50％左右。新工艺中段废水先经絮凝和过滤预处理以脱除纤维。接着，螺旋形和管形构型的有机和无机毫微过滤膜在ZXIc‘Pa的压力和40℃温度下进行操作以脱除95％的有毒的有机卤化物和有毒的有机化合物以及40％的盐类，渗透量为150l／h·m’。然后，滤波进入装有阴离子交换膜和阳离子交换膜的电渗析装置，在那里盐含量从1500mg／l减少至60mg…     

情迷大脸猫

新年的好处就是可以有一个冠冕堂皇的借口来拟定好多新的计划,或是把旧年里没有完成的事情重新包装一下,再假装在新年里有信心彻底完成它。旧年里的习惯和喜好会不同程度地在新年里或改变或发扬光大。于是,小编我自自然然地选择把旧年里对大脸型猫猫的喜爱一路继续下去。

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.     

软件，猛于虎矣

最近小弟的电脑处于“亚健康”状态——慢得象蜗牛、频繁报错但就是还不崩溃!这让我很为难,要死就死得干干脆脆,我也好马上“料理后事”(重装系统是小弟的一大法宝,菜鸟都这么干^O^),这么一直拖下去搞得我也快神经衰弱了。既然还不能给它“安乐死”,那我只好继续折腾下去了。不过这对总希望自己的爱机能够“多拉(同时运行更多的程序)快跑(运行速度更快)“的我来说,实在是一个不小的打击。

Single Photon Detection of InGaAs／InP APD Based on Gated-mode Operation at Telecom Wavelengths

Based on the commercially available avalanche photodiodes, the basic needs of gated-mode operation for single photon are discussed. Gated-mode technique based on the experimental data for detection of single photon is analyzed at communication wavelengths so that the basic operation parameters can decide properly for efficient detection of single photon. The bias voltage has related to the punch-through voltage in combining the cooling technique with synchronization to decrease the dark counts.     

动态VPN解决方案

一、概述 在现有的IP VPN组网方案中,一般采用CRE隧道、L2TP、IPSec等方式。但是这些方案都存在一个弊端,就是必须是按照事先的配置进行组网,并且要完成一个全联通的网络时(如图

谁是疯狂主妇的忠狗

主妇?是那个忙了事业,忙家庭,整天唠里唠叨的小妇人?当然不是。现在的主妇们,使用电脑键盘的熟练程度远高于使用电炒锅,要让她们做出十道各色小吃,不如让她们说出小吃的产地来得实际,她们在年终岁末也会算计,只不过她们算计的是今年全家应该到哪个国家去度假,或是还有哪项保险没有买。这样一群聪明、能干、风姿绰约的主妇身旁自然少不了一只善良、可爱的狗狗,才能形成一道独特的风景。
