Any given oil well has a finite supply of oil, and the wells' production follows the shape of a bell curve. Extracting oil is cheap and easy on the curve's upslope but after the the well has peaked – the point at which half of the well's oil has been extracted – production becomes more difficult and expensive. The output of the well begins to decline and will never recover; production falls steadily and the cost to extract the oil rises.

由於任何一个油井都只有固定的供应量，因此每个油井的原油产量都会遵循钟型曲线：一开始汲取原油很便宜也很容易，因此曲线是上升的，但当油井的产量到顶之后–也就是油井中的原油存量已被汲取出一半时–原油的生产就会变得愈渐困难且昂贵，油井的输出产量也开始下降，而且再也无法恢复，所以产量也将持续减少、使得生产成本不断增加。

SUMMARY A more accurate steady drillstring tension-torque model has been established by taking into account of drillstring, wellbore condition , drilling operation and drilling parameters. This model has been used in scientific calculations of directional and horizontal wells, such as determing the friction factor between wellbore and drillstring, calculating the hook load and rotating torque, ckecking the strength and stability of drillstring, optimizing well trajectory, computing the WOB while drilling by downhole motor and predioting the maxinum allowable length of horizontal section.

Ancient Greece and Rome has been the trading activities of the military forces strong and positive support of military activities: Augustus sent an expeditionary force south of the Arabian Peninsula in depth, in order to seize a number of businessmen in Rome the most important port; in科普托斯and the desert between贝雷尼切pass a road repair, wells along the way Stephen cited the creation of Tuen or post, every team has a team to desert the armed forces of the Roman official bodyguards and the Fayum oasis southwest between Fayyoum the business, as well as between the business and Egypt has taken similar measures to be protected.

古希腊罗马的贸易活动得到了强大的军事力量和积极的军事活动的支持：奥古斯都派出一支远征军深入阿拉伯半岛南部，为罗马商人占取了一些最重要的港口；在科普托斯和贝雷尼切之间的沙漠上修通了一条大道，沿途掘井引泉，开设屯或驿站，每队沙漠商队均有罗马官方的武装部队保镖，对于西南绿洲与法尤姆之间的商旅以及法尤姆与埃及之间的商旅也采取了类似的措施予以保障。

Based on the project requirements, the research has focused on the confined electronic states in the semiconductor surface quantum wells. The moden quantum theory and advanced material growth technology have been used. The interband transitions in the surface quantum well have been studied by the in-situ photo-modulated reflection spectroscopy combined with the molecular beam epitaxy system. The optical transitions, including the tansition between ground or excited states of the electron and hole states, have been directly observed.
