幫忙翻譯一下，萬(wàn)分感謝: 說(shuō)明一下860DSP是一個(gè)信號(hào)測(cè)量?jī)x器的型號(hào) Here is a good explanation of how the 860 in spectrum mode uses the different settings like dwell wide， narrow， and averaging to look at the spectrum data differently. 860 DSPI Spectrum Analyzer Set... 說(shuō)明一下860DSP是一個(gè)信號(hào)測(cè)量?jī)x器的型號(hào) Here is a good explanation of how the 860 in spectrum mode uses the different settings like dwell wide， narrow， and averaging to look at the spectrum data differently. 860 DSPI Spectrum Analyzer Settings Explanation In the 860 DSPI there are 3 different and unique spectrum analyzer “Detectors”. These detectors may alter the view of a signals appearance， depending on which is selected. Each detector can show a different picture on the same signal because of the way the detector functions. An important selection to our spectrum analyzer is the amount of digital snap shots to be taken. This will be the amount of digital snapshots that is taken in the allocated bandwidth before showing a picture. With this said， the more sampling that is put into the spectrum analyzer the slower it will seem to update， but more opportunity to capture ingress and other interference that can happen inside a cable plant. Dwell Wide- Dwell Wide takes the largest snapshot out of the amount taken， then the 7.5 MHz spectrum is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. Example: In Dwell Wide， with a 32 sampling rate set， this in turn means the 860 will dwell or sit on a portion of the spectrum defined above， take 32 snap shots， and then display the picture with the max amplitude before moving on to the next portion of bandwidth. Dwell Narrow- Dwell Narrow takes the largest snapshot out of the amount taken， then a 250 kHz spectrum slice is peak held as the 860 DSPI tunes across the selected frequencies in 250 kHz steps. The difference between Dwell Narrow and Dwell Wide is that Dwell Narrow only peak holds across a 250 kHz slice， where as Dwell wide peak holds the entire 7.5 MHz. Example: In Dwell Narrow， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum it will look at a 250 kHz slice of the 7.5 MHz and take its 32 samples. These 32 samples will be done in a peak hold fashion， then display the sample that contains the largest signal. Averaging: This detector when selected looks at a 7.5 MHz portion of the spectrum. When it tunes to the first 7.5 MHz portion of the spectrum， it takes into account how much sampling is selected， then takes it’s digital snapshots on the entire 7.5 MHz， averages those pictures together， then shows the final averaged picture. This detector is used for looking at large amounts of bandwidth. Example: In Averaging， with a 32 sampling rate set， this in turn means the 860 will go to the first 7.5 MHz of the spectrum， take it’s 32 digital snap shots， average those together， and show the average of the 32 snapshots. 展開(kāi)

In this study， active reforming catalysts for use of gasification of biomass compounds in aqueous medium were developed by depo-sition of platinum on various supports (activated carbon， titanium dioxide， alumina， single-walled and multi-walled carbon nano-tubes， graphene oxide and tungsten oxide-zirconium oxide) using nanotechnological approaches in supercritical carbon dioxide media. The effects of supports and platinum reduction methods have been investigated to optimize the catalytic activity of sup-ported platinum catalyst for hydrogen-rich gas production by aqueous-phase reforming of wheat straw biomass hydrolysates and glucose solution. 展開(kāi)
