    如果你不想要你的相機了,不如就送人吧。相機的感光元件對光線是非常敏感的,你這樣對著強光拍照對相機的損害是非常大的。很容易造成CCD 損壞?,F(xiàn)象是相機不能成像,照片成不規(guī)則彩色條紋,或全黑。你說的那種現(xiàn)象是不是相機在取景時屏幕上有紫色豎線?線的寬度會隨著畫面上光源的位置和大小改變?如果是那就是正?,F(xiàn)象。叫拖線這和CCD傳輸數(shù)據(jù)的方式有關(guān)。

    1、不是你相機的問題,是你使用不當(dāng)造成的。 2、對著太陽光拍照,由于光線太強可能會導(dǎo)致傳感器(CCD)受損或者因為負載太大而燒毀! 3、相機對著光源拍照,尤其是強光的時候一定要用濾光鏡,光線越強濾光鏡顏色越深,才能保護相機。

    我只能試著解釋這種問題了。 不知樓主聽說過富士S205的雪花門沒有。 可以百度一下。 這主要是CCD工作時間過長,產(chǎn)生了大量的噪點。呵呵,有點像樓主的機器。只是造出來早一年而已,一樣是SUPER的,EXR的。 首先F85是一個1/2尺寸的大CCD機,你應(yīng)該知道,對著太陽照的時候(不是夕陽,或朝陽這種光線較柔的時候)對機器的傷害有多大。這很有可能把它的CCD給燒掉。所以我分析,可能是富士吸取了S205機器的經(jīng)驗,對CCD的一種保護措施,閃爍可能就是對減少CCD工作頻率,或功率,而影響到總線的傳輸數(shù)據(jù)。由于CCD會產(chǎn)生高光溢出。所謂高光溢出就是一旦接收光子的“桶”(bucket)滿載,由額外光子轉(zhuǎn)化成的電荷便會溢出,并且這種溢出對像素值是沒有影響的,因此會導(dǎo)致像素值的感光不足或感光過度。當(dāng)電荷溢出至其旁邊的像素,使旁邊的像素在處理光子過程中感光過度。就像人一樣,工作久了,Z好休息一下,得到更好的工作效率。所以富士的做法是使CCD的溫度更低,以便獲得更少噪點的圖像。 樓主的機器應(yīng)該沒問題的,即便是佳能的機器也會有這種情況出現(xiàn),出現(xiàn)紫條。多摸索,這種經(jīng)典的半手動機還是很值得一練的~

Physical and physicochemical characterization The particle size distribution of the Ch-zeolite was determined using a laser diffraction equipment (CILASk 1064) and standard wet sieving (Mesh Tylerk series). Scanning electron microscopy (SEM-PHILIPSk XL20) was used for photomicrographs as well as to analyse the Ch-zeolite composition (Energy Dispersion X-ray, EDX). The sample was initially placed in a vacuum chamber for coating with a thin layer (few nanometers) of gold (Au). The specific surface area of the material was measured by the methylene blue technique and by nitrogen gas adsorption methods, with the latter also providing information about particle porosity. In the methylene blue adsorption method, aqueous solutions (50 ml) of methylene blue (100 mg l 1) were agitated using an orbital shaker (Marconik) for an hour at room temperature in the presence of different quantities of the Ch-zeolite (0.05–0.3 g). The suspensions were then allowed to settle for 23 h and the resulting supernatants were centrifuged at 5000 rpm before the analysis of the residual methylene blue concentration. Results obtained correspond to averaged values of three different experiments. The specific surface area was evaluated by the Langmuir model, assuming the formation, at high concentrations, of a dye monolayer and 1.08 nm2 molecule 1, for the cross-sectional area (Van den Hul and Lyklema, 1968). The Ch-zeolite specific surface area was evaluated by the nitrogen gas adsorption method, using automated equipment (Autosorb 1-Quantachrome Instrumentsk), employing multipoint BET isotherm adsorption data fitting. Also from these data, the porosity of the material was evaluated through parameters such as volume of total pores (d < 206 nm), surface area and volume of micropores (d < 2 nm; Micropore Analysis Method). Zeta potential measurements for the natural and ammonia loaded zeolite, as a function of medium pH, were determined using a Zeta Plusk equipment (Brookhaven Instruments). Suspensions (0.01% v/v) of the Ch-zeolite, previously sieved below 37 Am (400 Mesh Tylerk), in a 10 3 mol l 1 solution of KNO3 were used and the medium pH was controlled with the addition of HNO3 (pH< 7) and KOH (pH>7), separately. For the Ch-zeolite saturated with ammonia, suspensions of the material were prepared by the same procedure, except that the sample was loaded with 100 mg NH3–N l 1 of ammonia. 展開

Interim Report on Pressure Effect on Waxy-Crude Pipeline-Restart Conditions Investigated by a Model System Yield Phenomenon and Pipeline Restart. Yield stress is the threshold stress required to initiate ?ow of a viscoplastic ? uid. Waxy crude-oil gels are viscoplastic in nature and exhibit time-dependent Bingham plastic ?ow behavior during restart under imposed constant pumping pressure. The yielding process of a gel is a complicated process, and different models have been proposed to explain this phenomenon. Wardhaugh and Boger (1991) defined yield stress as the “shear stress at which the gelled oil ceases to behave as a Hookean solid.” Chang et al. (1998) adopted a three-yield stress concept: elastic limit (which defines the onset of viscoelastic creep), static (where fracture occurs), and dynamic yield stress (which describes the broken down structure after yielding). Among these three, only the static yield stress is used to design the restart pump for initiation of flow after shut-in. Several types of apparatus and different techniques (direct and indirect) have been used for determining the yield stress. The results obtained and conclusions regarding their validity and usefulness differ widely. Setups used are capillary U-tubes, large pilot pipeline facilities, lab-scale model pipelines, controlled-stress or -shear rotational rheometry experiments (CSR). The capillary tube and pilot-scale pipeline measurement tech-niques have been criticized as being unsuitable for understanding the yielding behavior of statically cooled waxy crude oils because of nonlinear pressure distribution, pipe compressibility effects, porosity of wax structure, and contraction effects (Wardhaugh and Boger 1991). However, the authors added that an exception to their conclusion was the work by Ronningsen (1992), where reasonable estimates of the yield stress as compared to model pipeline results were obtained with a constant stress rheometer. Recently, Lee et al. (2007) also reported the consistency between the concentric rheometer and a model pipeline system. In fact, model pipeline test is the most common laboratory method resorted to in gel strength measurement because of its geometrical resemblance to the real pipeline. In such tests, gel is formed under controlled conditions (cooling rate, aging temperature, etc.) and pressure is then slowly applied on one end of the gel until flow is observed. The gel strength (τ) is then calculated by: 公式1 展開

Whenliquidisheateditevaporates.Theevaporationprocessisdependentonpressure,temperatureandcompositionoftheliquidandgas.Gascanalsocondense.Inadditionthereisaconvectiveheattr... When liquid is heated it evaporates. The evaporation process is dependent on pressure, temperature and composition of the liquid and gas. Gas can also condense. In addition there is a convective heat transfer between the liquid and gas zone that must be considered. The surfaces in the gas zone also radiates from the shell to the liquid. During the blowdown process mass is usually evacuated from the gas zone, but also liquid might be released. The rate of release is dependent on density and pressure as well as the release area. As pressure and temperature change, the properties of all materials change. This has to be considered in a prediction of a blowdown process. The main purpose of a blowdown process is as earlier stated to maintain integrity of the equipment. The strength properties of the shell are the key factor on that matter. The strength is dependent on the inside pressure as well as the support forces. If the exposing forces produce stress that exceeds the ultimate tensile stress (UTS) in some regions, the integrity of the equipment is no longer maintained. In the design phase of a process plant, these aspects are crucial and must be included as a dimensional factor. For that reason prediction of the blowdown process is essential. Lately some new standards has been introduced to the industry on this matter [3] and [4]. VessFire [1] and [2] is a multi physics system designed for calculation of this kind of problems. It has been applied for some time in the oil and process industry on many projects. The system satisfies the requirements for predictions outlined in [3] and [4]. It includes all aspects described above including integrity of the shell. As part of the verification process some experiments where performed. Some of the experiments are presented here. EXPERIMENTAL STUDY The purpose of the experiments was to investigate the evaporation process and the heat transfer to the liquid and vapour. In a complex system it is important to reduce unknown parameters as far as possible. Exposure from a flame is difficult to control. Flux measurements are point values and not necessarily representative for the average exposure. In order to control the heat exposure it was decided to apply an electric heating system. The system and the verification of the system is described in [5], [6] and [8]. The furnace was built inside a supporting tube. Figure 2 shows a general arrangement of the experimental outfit. A 0.05 mm stainless steel foil formed as a tube, 300 mm in diameter, generated the heat. The power supply was based on a 3-phase alternating current system giving 48 Volt output as maximum. The top exposure had a limit of 300 kW. The foil had a surface of about 1 m2, giving a heat flux up to 300 kW/m2. The power input could be continuously regulated from zero to maximum load. Each experiment was started from zero and brought up to the required load within a few seconds. After that the surface temperature of the heating foil was kept constant during the exposure period. Experiments with both dry objects as well as water filled object were performed. In this paper only water filled experiments are presented Figure 2 General arrangements drawing of the experimental furnace including the specimen and its support Figure 3 Illustration of the heating unit. The black part is copper conductors for the foil. The grey part is the heating foil exposing the specimen. The foil is equipped with thermo-elements all marked H, except H5 which is the temperature in a copper ring and H6 which is the temperature between the insulation and the supporting tube. 展開
