本文介绍了一个简单、具有快速响应能力的过流故障检测器，用于低压系统的电路保护。该方案与专用的热插拔控制器不同，热插拔控制器利用欠压检测产生较长的启动延时，本文所介绍的电路在输入电压上升到2．7v以上150gs后才提供保护。当然，在上电过程中，该电路会通过限制外部P沟道开关管的栅极电压限制瞬间启动电流。

Study on New Pretreatment Combining Dilute Acid Treatment and Organic Solvent Water / Ethanol for Biorefinery： Application to Switch Grass

引用

Journal of Life Sciences 2010年第3期4卷 25-32页

作者： Dachun Gong Yingping Huang M. Holtman kevin Ruiping Li Franqui-Espiet Diana J. Orts William Alan G.Macdiarmid Institute of Renewable Energy China Three Gorges University Yichang 443002 China Western Regional Research Center Agricultural Research Service US Department of Agriculture Albany CA 94 710 USA

Switch grass was developed as a pioneer energy crop in USA with great industrial prospect. It contains about 60% sugars and 18% lignin. The purpose of this research is to find pretreatment process to fractionate cellulose, hemicellulose and lignin from switch grass to obtain much more useful chemicals and enhance the residue solid to be hydrolyzed by enzymes. The six different pretreatment methods were studied, such as hot water pretreatment （HWP） alone, dilute acid pretreatment （DAP）, ammonia pretreatment （AP）, lime pretreatment （LP）, organosolv water / ehanol pretreatment （OWEP）, and organosolv water / acetone pretreatment （OWAP）. It was the best method combining DAP with OWEP because the hemicellulose sugars were recovered in the first residual liquid while a varied amount of cellulose was retained in the residual solid and the lignin fraction was obtained by simply adjusting the pH from the second liquid. The result shows the optimal two-stage process consisted of the first stage DAP at 428 K for 7 min with 0.8% sulfuric acid, resulting in 79.82% glucose recovery yield and 98.74% xylose removal and the second stage OWEP at 468K for 20 min in 45% （v / v） ethanol with 0.4% NaOH, resulting in 62% total glucose yield 99% xylose and 80% lignin removal. After enzymatic hydrolysis, the glucose yield was up to 92.6%, compared with 16% yield from untreated switch grass. Scanning electron microscopy （SEM） highlighted the differences in switch grass structure from the various pretreatment methods during biomass fractionation.

很多高性能数据采集系统用±5v电源比用单一5v电源能获得多种好处。这些好处包括处理较大信号幅度的能力。这增大了系统的动态范围和有助于改善信噪比。工作在±5v也增大活动范围,这对于信号调理是很重要的。工作在±5v的调理电路与工作在5v的电路相比,其活动范围为其两倍,这允许不用限幅就能容易处理±2.5v信号。另外,较大的活动范围避免了电源正负限工作的限制,并扩大了高性能运放和模/数转换器(ADC)的选择。开关电源或电荷泵电源是从单5v电源产生-5v电源的有效方法。然而,这些电路通常最好不与ADC配用,
