查询词典 circulation time

In order to describe in detail the structure of mesoscale atmosphere circulation and its evolution, symmetry theory are extensively used in the past fifty years. A large number of wind tunnel and water tank experiments are practiced to reshow the physical process that often appear in the atmosphere and, to some extent, successfully explain many atmsophere circulation characters in surface layer. But because of the planetary reflection and small Re number deformation, these physical experiments can' t represent real conditions of the atmosphere, they also can' t distinct viscous boundary layer separation and non-viscous dynamical separation as well as show the circulation response to surface diurnal heating.

为了详细描述复杂地形区域大气中尺度环流的结构和特征，过去50年来人们广泛采用相似理论，利用风洞和水槽实验再现大气中的物理过程，并在一定程度上成功地给出了大气近地层的一些环流特征，然而由于边界层反射和小Re数形变作用的影响，物理实验的结果并不能真实地再现大气中的实际状况，尤其是不能正确区别边界粘性分离流场和大气非粘性动力分离气流，环流场对地形下垫面日周期热强迫的响应过程也难以再现。

When local hypergene life prosperous, deposition relative many; Otherwise when the life is in the murky time, relative small; When deposits the many stratum participation internal heat circulation, the surface activity is relatively violent, has the possibility to mean surface Earth life a disaster time, when deposits the few stratum participation internal heat circulation, the surface activity is relatively stable, has the possibility to mean the life an epacme, this is the Earth life periodicity deconstruction and the newborn basic internal reason is at.

当地表生命繁盛时，沉积就相对较多；反之当生命处于低迷时期时，就相对较小；当沉积较多的地层参与内热循环时，地表活动相对猛烈，就有可能意味着地表地球生命的一个灾难期，当沉积较少的地层参与内热循环时，地表活动相对稳定，就有可能意味着生命的一个繁盛期，这就是地球生命周期性毁灭与新生的根本内部原因所在。

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。

Chohwa , which was made of standardized mulberry-bark paper early in the Joseon period, become the first legal paper money and was used as a medium of exchange in place of coins.From the 17th century until the end of the 19th century, Sang Pyong Tong Bo copper coins were the most widely circulated currency.The mintage and circulation of modern currency began during the last years of the old Korean Empire as a result of contact with the West.Around the time of the trial adoption of the gold standard in 1901, gold and silver coins were in circulation along with some Japanese bank notes.In 1909, the Bank of Korea was founded in Seoul as a central bank and began issuing currency of modern type.After Korea lost her sovereignty to Japan in 1910, the Bank of Korea was renamed the Bank of Chosn, until Korea's independence in 1945 at the end of World War II.

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。
