真实气体

As when a Vultur on Imaus bred, Whose snowie ridge the roving Tartar bounds, Dislodging from a Region scarce of prey To gorge the flesh of Lambs or yeanling Kids On Hills where Flocks are fed, flies toward the Springs [ 435 ] Of Ganges or Hydaspes, Indian streams; But in his way lights on the barren Plaines Of Sericana, where Chineses drive With Sails and Wind thir canie Waggons light: So on this windie Sea of Land, the Fiend [ 440 ] Walk'd up and down alone bent on his prey, Alone, for other Creature in this place Living or liveless to be found was none, None yet, but store hereafter from the earth Up hither like Aereal vapours flew [ 445 ] Of all things transitorie and vain, when Sin With vanity had filld the works of men: Both all things vain, and all who in vain things Built thir fond hopes of Glorie or lasting fame, Or happiness in this or th' other life; [ 450 ] All who have thir reward on Earth, the fruits Of painful Superstition and blind Zeal, Naught seeking but the praise of men, here find Fit retribution, emptie as thir deeds; All th' unaccomplisht works of Natures hand, [ 455 ] Abortive, monstrous, or unkindly mixt, Dissolvd on earth, fleet hither, and in vain, Till final dissolution, wander here, Not in the neighbouring Moon, as some have dreamd; Those argent Fields more likely habitants, [ 460 ] Translated Saints, or middle Spirits hold Betwixt th' Angelical and Human kinde: Hither of ill-joynd Sons and Daughters born First from the ancient World those Giants came With many a vain exploit, though then renownd: [ 465 ] The builders next of Babel on the Plain Of Sennaar, and still with vain designe New Babels, had they wherewithall, would build

好像一只伊马乌斯山上生长的秃鹫，在雪岭环绕着鞑靼人流浪的地方，食饵的缺乏迫使他们到放牧羊群的诸小山上去，吃饱了羊羔的肉之后，飞向印度恒河或印度河的发源地；途中降落在丝利刻奈的荒野，那儿的中国人用风帆驾驶藤的轻车。魔王如同这鸷禽，独自徘徊在如海洋一样多风的大地上，寻觅食饵。他真觉孤单，因为那里还找不到其他生物，无论是活，是死；只是后来，罪恶用虚荣填满了人的事业，才从地上升起一切虚无缥缈的东西，像飘浮的气体一般升腾到那里：包括一切虚幻的东西，以及所有人，那些把他们的光荣希望、不朽声名、今生来世的幸福都建筑在虚无缥缈上的人们。有些人在今世得了报应，即可悲的迷信和盲目的狂热追求所结的果实，只追求凡人的称赞，和他们的空虚行为相称的酬报，空虚。自然所未完成的工程，流产的、畸形的、乱七八糟混杂在一块儿，在地上消灭了，都飞到这里来，在这里徒然彷徨，直到最后破灭；有些人把梦想寄托在邻近的月球上，那同样是荒谬的。在那银色的世界里，有各种各样的类族：近乎真实的居民，超升的圣者，介乎天使和人类之间的中性精灵；神的众子和人间女子所生的巨人族，首先从古代世界来，当时很出名，还带来了许多空幻的功业。其次是示拿平原上巴别塔的建筑者，他们还有虚空的计划，要是材料有余的话，还要建筑些新的巴别塔。

Our filters have been tried and true for most any demanding compressed gas filter application.

The modified expression of the broad emission-line profiles ire derived for the outflow kinematics model of the BLR driven by the radiation pressure. Taking into account the difference between the two lines HeI λ5876 and Hβ, it is shown the fact that the observed line width of HeIλ 5876 is broader than that of Hβ cannot be explained by the popular outflow BLR model evoked by W. G. Mathews. For comparison, line profiles of the gravitational infall model and orbital disk model are also calculated; the later is in good agreement with the observations Thereupon, conclusion is reached that the gravitational infall is an important process in the real BLR gas motion.

1推导了辐射压加速宽线云团径向外流，以及引力下落和转动等BLR运动学模型的谱线轮廓表达式，并考虑到光致电离计算表明的云团本身对Hβ和HeIλ5876谱线的辐射差异，用数值方法计算了它们的谱线轮廓，发现普遍流行的辐射加速气体外流模型不能解释HeIλ5876线宽大于Hβ线宽的观测事实，而引力下落模型则可以较好地解释观测，因此我们倾向于认为、径向内流运动很可能是BLR内的发射线云团真实运动的一个重要成分。

The conclusions can be drawn through numerical simulation: The hydrate-forming region becomes small with increasing circulation rate and inhibiter concentration, and it is possible to make the hydrate-forming region away from sea floor by increasing circulation rate and inhibiter concentration, thus preventing blowout preventer lines from hydrate plugging; the decrease in gas volume fraction in the annulus due to hydrate formation reduces pit gain, which can delay the detection of well kick; the possibility of hydrate presence at a relatively low gas production rate is much greater than that at a relatively higher production rate; the bottom hole pressure is affected little by hydrate phase transition, and it is allowable not to consider hydrate phase transition when the bottom hole pressure is calculated; shut-in casing pressure cann't truly reflect gas kick due to hydrate formation and the situation is getting worse with time

模拟计算结果表明：溢流期间，天然气水合物的生成区域会随着循环流量的增大或抑制剂浓度的提高而减小，可通过增大流量和抑制剂浓度使水合物的生成区域脱离海底，减小防喷器管线被堵塞的危险；水合物的生成使环空中气体体积分数降低，泥浆池增量减小，给溢流检测带来延迟；当检测到有气侵发生时，水合物藏分解速率比较小时，井筒中生成水合物的可能性要比分解速率大的情况下更为严重；水合物相变对井底压力的影响较小，在工程中计算井底压力时可以忽略；由于天然气水合物的生成使得关井套压值不能真实反应气侵情况，而且随着时间的增加情况会更加严重。

The preliminary chromatogram data were resolved with Mallat algorithm of wavelet analysis theory. This method that resetting the high frequency signals, reconstructing low frequency and then correcting the background signals in the original signal was to avoid the data skewness with negative digital points after background correction and achieve the baseline correction; according to the study and analysis of simulated data including curve background and real data of the needle-plate and free metal partials insulation defects, the method is effective; the best wavelet function of the background correction is Db5 and the best resolution times of the background correction is 8 for chromatogram data of SF_6 decomposition products, based on the calculation with different wavelet functions and resolution times.

在初步获取的气相色谱数据基础上，运用小波分析技术中的Mallat算法对色谱数据进行小波分解，采取将高频信号置零，重构低频背景信号，再用原始信号扣除背景信号的方法，并对背景信号进行纵向平移以避免扣除后出现负数据点造成色谱峰失真的题目及达到色谱图基线校正的目的；通过对含曲线背景信号的模拟色谱数据和针-板、自由金属微粒缺陷下的真实数据的计算研究表明，该方法的应用是有效的；并通过对不用小波函数和不同分解次数的背景扣除计算，确定了SF_6气体放电分解组分色谱背景扣除所选用的最佳小波函数为Db5小波和最佳分解次数为8次。

The former were closed relatively to real variety process of gas space nature.

Incurrent research, aiming at the rupture problem engendered in the shooting process of acertain 5.56mm automatic rifle, the strain and stress distributions on the cartridge caseunder the action of axial pull have been analyzed. Based on the theories of elastic-plasticmechanics and contact mechanics, a mathematic and physical model of the cartridge-caseand chamber system has been set up; and based on the platform of the general softwarepackage APDL of ANSYS for finite element analysis, a parameterized model of thecartridge-case and chamber system has also been established. The method for nonlinearFEA has been adopted to analyze the stress distribution on the entire cartridge-case andchamber system, and the method of contact element has been employed to investigate thecontact stress between the cartridge case and chamber, and then the influences of frictioncoefficient and locking space on the static and dynamic stress and strain response of thecartridge case and chamber to the action of power gas have also been discussed. On thebasis of a lot of numerical tests, a kind of element Plane13, which is concentrated incoupled computation of heat and construction, has been used finally to simulate thetransient response of the cartridge-case and chamber system to the power gas. Throughloading the temporary thermal characteristics of explosive gas in the procedure of emulate, the corresponding transient thermal stress distributed on the entire system under thecombined load of transient thermal stress and transient pressure has been obtained. Owingto these comprehensive considerations, the numerical results obtained in this paperrepresent the actual situations comparatively exactly.

This three region model is different from two region model available. The behavior of the nitrogen in the volume compensator was simulated by polytrophic process similar to real variety process of gas, or constant temperature process of gas with the valve opening in the volume compensator and adiabatic process of gas with the valve closed in the volume compensator, respectively. The former were closed relatively to real variety process of gas space nature.

For this reason, it has become the main objective for the development of hypersonic ground facilities to simulate real gas effects, especially the non-equilibrium chemically reacting flows.

The conclusion that dissolved gases in gas composition and content of transformer could embody the inside of the transformer"s situation about "the insulation fault effectively is concluded.In the research of power equipment fault diagnosis based dissolved gases in transformer oil, the fault type increase clearly with the fault development. Traditional way is inability to faults diagnose of electrical equipment such as transformer that the fault reason, phenomenon and principle are indeterminacy etc.

在以油中溶解气体分析电气设备故障的模式识别研究中，当故障进一步发展，待判别的类型将显著增加，由于传统的诊断方法缺乏对样本数据的科学分析，不能够真实体现特征量数据的规律，将不可避免的面临准确率下降的问题，且不可能提供类间相互关系或演变过程的信息，因此用新的诊断方法来解决此类问题十分必要；本文在对目前变压器内部绝缘故障常用诊断方法总结分析的基础上，利用模糊数学的思想，提出以油中溶解气体为特征量，采用模糊聚类的方法对变压器内部绝缘故障进行诊断。
