In pressure of influence underbalanced drilling,such as drilling fluid column pressure,annulus pressure,underbalance pressure,wellhead back pressure and formation pressure etc.,the formation pressure is basic pressure.Because all pressure calculations are built on the basic pressure.

认为在影响欠平衡钻井的钻井液静液柱压力、环空压耗、欠压值、井口回压、地层压力中，地层压力是首先要搞清楚的最基础的压力，最好先求出地层压力而不必急于进行欠平衡钻进，因为一切欠平衡的压力计算都是建立在这个基础压力之上的；再根据地层压力确定合理的欠压值，确定所用的钻井液密度。

According to the grey theory,a new method of pore pressure prediction for undrilled formation beneath the bit was offered in the thesis,and a grey model of formation pore pressure prediction while drilling was es.

Meanwhile, amorphization induced by ion mixing, beginning also with multilayered films, has been extensively studied since early 1980s and some scientists have argued that a positive heat of formation is unfavored for amorphous alloy formation.

同时，80年代初以来，人们也对多层膜离子束混合诱发非晶化开展了广泛的研究。一些学者认为正的生成热不利于非晶态合金的形成。

Based on the design of the interfacial free energy, the positive heat of formation, which is an unfavored factor for alloying, could be overcome for forming amorphous alloys in those equilibrium immiscible binary metal systems, thus confirming the thermodynamic model for metallic glass formation proposed previously by this research group.

二、通过界面能的设计可以克服正生成热的不利影响而制备出非晶态合金，论证了本研究组提出的非晶化相变的热力学模型的合理性。

By analyzing the general characteristics of information goods such as high fixed cost, low marginal cost, this paper roundly discusses the formation reasons of the pricing discrimination in the market of the information goods, which has grown unhealthily in traditional failure price formation mechanism.

1引言 随着信息网络技术的快速发展，信息技术革命席卷全球各国的经济，各种不同类型和日趋多样化的信息商品竞相投向市场。信息商品具有高固定成本、低边际成本等特征，与工业时代商品的成本、价格特征有很大的不同…。

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先，钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能，并且有明显的协同作用，从而能抑制部分点蚀核的产生；其次，钼酸盐复配缓蚀剂的使用，从电化学的角度分析，具有明显的钝化性能，且钝化区间较宽、维钝电流密度较小，从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化，得到有效的修复；最后，对于还有部分蚀孔发展成为闭塞腐蚀电池的情况，钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐，从而有效地减缓了点蚀的恶化，抑制了腐蚀的发展。

This dissertation presents the effects of formation potential range, heat treatment, and the thermal additive, vinylene carbonate, on the formation and stability of SEI by electron spectroscopy for chemical analysis, fourier transform infrared spectroscopy, differential scanning calorimetry, nuclear magnetic resonance, AC impedance, and certain standard electrochemical techniques.

因此，本论文从三方面著手，分别探讨化成程序的电位范围、热处理、以及热添加剂乙烯碳酸酯（vinylene carbonate；VC）对此钝化层造成的影响。所采用的分析工具包括X光线电子光谱、富利叶红外光谱、差分扫瞄式卡计、核磁共振光谱、交流阻抗频谱及一些标准的电化学分析技术。

Although aqueous extract of Andrographis paniculata, aqueous extract of Mesona chinensis, ethanolic extract of Verbena officinalis at 1.25 μg/mL could only decrease TBARS formation, and ethanolic extract of Glossogyne tenuifolia, ethanolic extract of Mesona chinensis only decreased carbonyl formation at 1.25 μg/mL, ApW, McW, VoE, GtE and McE at 5 μg/mL appeared to have a lengthening in lag phase.

虽然，1.25 μg/mL 穿心莲水萃取物、仙草水萃取物、大陆马鞭草乙醇萃取物只能减少TBARS 的形成，而1.25 μg/mL香茹乙醇萃取物、仙草乙醇萃取物 McE）只能减少蛋白质羰基(carbonyl groups 的形成，但在5 μg/mL 的ApW、 McW、 VoE、 GtE 和McE 可明显延长迟滞期。
