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

Caution:Do not place your finger over the vent(it pressurizes the sensor) to test the flow indicator when gas is flowing to the sensor.removing your finger (the restriction) generates a vacuum on the sensor and maydamage the sensor(voiding the sensor warraty). Positive pressure applications: If the sample pressure is greater than 30 psign an external pressure regulator(optional) is required upsteram of the analyzer to control of sample flow.a pressure regulator with a metallic diaphragm is recommended to prevent high oxygen reading that cuold result from the use of diaphragms constructed of more gas permeable materisls. If other optionoal sample system components such as coiled metal tubing(samples must be colled to at least 35-40℃ for continuous use)，coalescing filters ，scrubbers，etc.are required install the pressure rugulator after the coiled tubing and bofore the other components and the analyzer.a scrubber requires a flow valve upstream for optimum efficiency and response time and that the analyzer flow valve is opened completely. Atmospheric or slightly negative pressure applications: For accurate high ppb and/or low ppm range measurements，an optional simple pump is required downstream of the analyzer to draw the sample through the analyzer.The cacuum drawn on the analyzer and sensor should not exceed 4”of water. Caution:Use ofpump downstream of the sensor requires the floe control valve upstream of the sensor be completely opened to avoid drawing ercessive vacuum in the sensor，which can damage the sensor. If pump over-loading(due to the limitation of low flow rate of the sample gas)is a comsideration，a second throttle valve on the pump’s inlet side may be necessary to provide a bypass path，as illustrated below，to prevent the pump from over-loading and over-heating while miantaining the required sample flow rate within the above-mentioned parameters 展開

The presence of a gaseous environment in the specimen chamber modifies the electron beam profile. In order to fully understand the beam-gas interaction， we have investigated the beam-diameter effect for two gases (helium and air) by Monte Carlo simulation. In this calculation， we have assumed that the electron beam is Gaussian and we have explored the influence of the nature of the gas at low voltage. When the beam diameter varies between 1 and 100 nm， there is no influence on the beam profile for these two gases. The resolving power of the HPSEM is not affected by the beamgas interaction. These theoretical results have been compared with experimental images obtained at low voltage under air and helium gases. The variation of image quality at low voltage has confirmed the interest of helium for use in a Field Emission Gun SEM (FEGSEM) in high pressure (or low vacuum) conditions. q 2004 Elsevier Ltd.

Fortunately ， this is not necessary. The transfer function can be derived instead by certain algebraic manipulations of those of the subsystems or blocks. Some examples will show this block diagram reduction technique and provide some useful results. Example 1.8.3 The configuration in Fig.1.5(a)，which includes a minor feedback loop， is very common in servomechanisms . Derivation of C/R by the approach of Example 1.8.2 would be laborious ，but become simple if the result in(1.33) is used. It is applied first to reduce the minor feedback loop C/M to a single block ， as shown in Fig.1.5(b). but (1.33) applies again to this new loop and now yields the closed-loop transfer function. Example 1.8.4 In a tow-input system， the additional input D often represents a dis-turbance ， such as a supply pressure variation in the level control example in Section 1.3 . With the additional block L ， the diagram models the effect of the disturbance on the system. For linear systems the principle of superposition applies， and the total output is the sum of the outputs due to each input separately. Thus the out-put due to R is found as before， and while finding that due to D， R is put equal to zero. The rule of Example 1.8.2 applies when finding the response to D， but note that the product of G2. Note also that for R=0 the minus sign for the feedback at R can be moved to the summing junction for D. Inspection now yields. Example 1.8.5 In fig.1.6 the two feedback loops interfere with each other. The rearrangements (a) and (b) are alternative first steps to make the result in (1.33) again applicable . Verify that neither changes the system， and that applying (1.33) twice to (a) or (b) yields the closed-loop transfer function. 1.9 Conclusion In this chapter a general introduction has been given first， including physical discussion of some fundamental features of control system behavior. A level control example led to a common block diagram configuration. Laplace transforms led to the transfer function description of dynamic behavior， and block diagram reduction to the description of an interconnected system of blocks. The application of transfer functions and transforms and transforms to calculation of the response c(t) to an input r(t) and initial conditions has been demonstrated for cases where the roots of the denominator of the transform C(s) are real and distinct. This provides a framework and motivation for study of the next chapter， and a basis for detailed discussion of transient response in Chapter 3. It also allows for an introductory examination of some of the effects of feedback in the problems below. 展開

Attaching the Sample Chuck You will need a #2 Phillips screwdriver for this step. Following the details shown in Fig. 2-4， install the sample chuck by first aligning the pins on the bottom of the sample chuck with the receptacles on the alpha- SE base. Then tighten the upper two captive thumb screws. Next， use the Phillips screwdriver to tighten the lower two captive screws. Don’t over tighten the screws! It will make it difficult to remove them in the future; just ensure that the screws are snug. Finally， connect the vacuum line from the sample chuck to the vacuum fitting on the alpha-SE base. Releasing the Z-stage Shipping Lock To access the Z-stage shipping lock， first loosen the captive screw on the lamp/shipping lock access door， then open the access door by rotating 180°， as shown in Fig. 2-5. To release the Z-stage shipping lock， stand in front of the ellipsometer and use your left hand to balance the weight of the Z-stage (you will feel it lift up slightly). It will be difficult to release the shipping lock if you apply too much or not enough upward force. Next， use your right hand to move the shipping lock to the operating position (to the right， see Fig. 2-6). If the lock is hard to move， you can use a tool to gain more leverage. The shipping lock will move about 1/3” [8mm] to the right. Checking the Lamp Check that the QTH lamp in fully seated in the lamp housing. The lamp is located behind the actuator screw (see Fig. 2-6) and has two white wires protruding from the back of the lamp. Simply push down on the lamp ensuring that the lamp is fully seated in the lamp housing. Rotate the lamp/shipping lock access door to the closed position and hand tighten the captive screw. 拒絕翻譯軟件，翻譯軟件我自己也會用 不是用翻譯軟件我就看不懂，只是，上來找人翻譯就是希望翻譯出比較容易看懂，不需要自己對照就可以看的說明書，如果用翻譯軟件，根本就詞不達意，還是要自己對著原文件核實 既然用了那么多積分，就希望有相當(dāng)?shù)某晒?，如果用翻譯軟件混積分，那就是人品問題了 還有，某些人不要不懂亂說混積分 展開

A reversed-phase ion-pairing high-performance liquid chromatography (RP-HPIPC) method for the separation of a complex mixture of heparin-derived oligosacchrides has been developed by a stepwise optimization of the mobile phase， in which the concentration of ion-pairing reagent， mobile phase pH， and acetonitrile concentration were varied. The resolution of more than 30 oligosaccharide components was obtained， under optimized conditions， in an analysis time of less than 30 min. This represents the first RP-HPLC method that can separate a complex mixture of both small and large sulfated oligosaccharides in a single chromatographic step. The heparin-derived oligosaccharides， in this mixture， can also be separated under a second set of RP-HPIPC conditions using a volatile ion-pairing reagent， tributylammonium acetate， to aid in the recovery of individual sulfated oligosaccharides. Moreover， it was possible to replace sodium chloride gradient， required for eluting highly sulfated oligosaccharides， with a fixed， low concentration of a volatile salt， ammonium acetate， by utilizing an acetonitrile gradient. This solvent system might make it possible to directly interface this RP-HPIPC separation with mass spectral analysis. ??2003 Elsevier B.V. All rights reserved.
