如果你不想要你的相机了，不如就送人吧。相机的感光元件对光线是非常敏感的，你这样对着强光拍照对相机的损害是非常大的。很容易造成CCD 损坏。现象是相机不能成像，照片成不规则彩色条纹，或全黑。你说的那种现象是不是相机在取景时屏幕上有紫色竖线？线的宽度会随着画面上光源的位置和大小改变？如果是那就是正常现象。叫拖线这和CCD传输数据的方式有关。

1、不是你相机的问题，是你使用不当造成的。 2、对着太阳光拍照，由于光线太强可能会导致传感器（CCD）受损或者因为负载太大而烧毁！ 3、相机对着光源拍照，尤其是强光的时候一定要用滤光镜，光线越强滤光镜颜色越深，才能保护相机。

我只能试着解释这种问题了。不知楼主听说过富士S205的雪花门没有。可以百度一下。这主要是CCD工作时间过长，产生了大量的噪点。呵呵，有点像楼主的机器。只是造出来早一年而已，一样是SUPER的，EXR的。首先F85是一个1/2尺寸的大CCD机，你应该知道，对着太阳照的时候（不是夕阳，或朝阳这种光线较柔的时候）对机器的伤害有多大。这很有可能把它的CCD给烧掉。所以我分析，可能是富士吸取了S205机器的经验，对CCD的一种保护措施，闪烁可能就是对减少CCD工作频率，或功率，而影响到总线的传输数据。由于CCD会产生高光溢出。所谓高光溢出就是一旦接收光子的“桶”(bucket)满载，由额外光子转化成的电荷便会溢出，并且这种溢出对像素值是没有影响的，因此会导致像素值的感光不足或感光过度。当电荷溢出至其旁边的像素，使旁边的像素在处理光子过程中感光过度。就像人一样，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的温度更低，以便获得更少噪点的图像。楼主的机器应该没问题的，即便是佳能的机器也会有这种情况出现，出现紫条。多摸索，这种经典的半手动机还是很值得一练的～

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. 展开

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 ﬂow of a viscoplastic ﬂ uid. Waxy crude-oil gels are viscoplastic in nature and exhibit time-dependent Bingham plastic ﬂow 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 展开

高分请高手帮忙翻译英文文献资料（4）: 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. 展开
