By systemic researching and simulating experiment, the text gains such results as follows,1. On the base of sufficiency research on the oil-gas hydrocarbon systemic chemistry composing and the physical chemistry characters, we traverse the mechanism of the paraffin's deposition. Then we consider that paraffin deposition is a complex process ofphysical chemistry, which includes more than one single mechanism.2. Traversing and comparing the literature in detail on different factors that has effect on paraffin deposition, the available experimental methods on paraffin deposition, prevention of paraffin deposition, and removing of the deposited paraffin on the spot.3. Ameliorated the laser equipment of solid particle inspecting system and the corresponding test methods. Determine WCT of dead oil and live oil from KS101 well under different pressure with this system. The result implies that dead oil has opposite regulation on paraffin deposition temperature to live oil.4. A vapor-liquid-solid envelop is drawn by superposition regular vapor-liquid envelop and WCT curve thereby explained that the departure and quick raising of the curve in the low temperature zone is caused by the appearance of paraffin in solid phase.5. Estimation is made to determine the depth of paraffin deposition in the well.

通过系统的研究和实验模拟，本文取得了以下研究成果：(1)在充分调研油气烃类体系的化学组成及其物理化学特征的基础上，详细研究了石蜡沉降的机理，认为石蜡沉积是一个复杂的物理化学过程，是多种机理共同作用的结果；(2)深入调研并综合阐述了影响石蜡固相沉积的各种主要因素，对目前国内外常用的有机固相沉积实验研究方法和现场清防蜡措施也做出详尽的描述，并加以对比评价；(3)改进了油气藏开发重点实验室自行研制组装的高温高压下测定固相沉积的激光装置和测试方法，并用该套设备测定出柯深101井的井口脱气油样和凝析气平衡油样不同压力下的析蜡点，实验结果表明，脱气油和平衡油析蜡规律相反；(4)将常规气-液两相相图和析蜡曲线叠加得到了气—液—固三相相图，从而解释了气-液两相等液量线在低温区域偏离正常并快速上翘是由于体系有石蜡固相出现；(5)利用实验测试的析蜡温度预测析蜡位置，表明只有在距井口465m油管以上会有蜡析出。

IT IS too late to warn of a civilian slaughter in north-eastern Sri Lanka. The "bloodbath has become a reality," said the UN's spokesman in Colombo on May 11th, as news of the latest atrocity emerged from the crowded beach where the army and Tamil Tiger rebels are fighting their last battle. On May 9th and 10th 480 civilian refugees are reported to have been brought dead or dying to a makeshift hospital in the war-zone, victims of shellfire.

如今再为斯里兰卡东北部的平民屠杀发出警报为时已晚。5月11日联合国发言人在科伦坡说："血腥屠戮已成现实"，此时有关最新暴行的新闻正从拥挤的海滩上不断传来，而政府军与泰米尔猛虎反叛分子正在那里进行最后的搏杀。5月9日与10日，有480名已死或将死的难民被送往战区的一个临时医院，成为炮火的牺牲品。

Here is in fact waste's opposite – fulsome space that is a zone for visions. Inspiration can easily strike quick in such a space – pimpled with mounds concealing ancient dead.

而这里恰恰是蛮荒的反面，有着无尽的想象空间，灵感在在这块四处隐掩着先灵坟墓的土地上生根发芽。

This paper simulates how the additional flutter signal impacts on oil pressure and actuator output when the dead zone is kept. The proper principle of flutter signal for jam diagnosis is given. Based on the given flutter signal, different jams caused by jam of the EH servo valve under different operating condition are simulated and the output of the oil pressure and actuator are presented. Meanwhile, waving threshold of the oil pressure for jam diagnosis is given. The simulations and analysis prove that the jam fault identification of the EH servo valve based on flutter signal is feasible.

在应用附加振颤信号防止和识别卡涩故障的前提下，确定了振颤信号的选取原则，并采用仿真的方法深入探讨了3种变工况条件下不同卡涩程度对电液转换器油压和油动机输出的影响，提出了油压阈值的卡涩判断标准，论证了基于振颤信号幅值与频率响应监测电液转换器卡涩故障诊断方法的可行性。

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

Boredom was a constant companion—one crewman cursed "the monastic life we lead in this dead zone"—but Nansen's men did not suffer."I myself," he wrote,"have certainly never lived a more sybaritic life."
