手持式GPS测量在地球化学勘查中的应用

在大比例尺的化探测量中，用GPS单点绝对定点技术来进行测网的布设，减少了控制测量环节。降低了生产成本。因此，GPS绝对定点在化探测量中仍有应用的前景。但是，绝对定位时必须做到：(1)合理选择校正的控制点(三角点或四角点)；(2)正确校正参数；(3)定期地检测仪器；(4)保证仪器的高度角和有效工作时间。本次该方法应用在化探的测网布设中。实测面积7km^2，经传统测量仪器检查验收，证明文中提出的方案完全可以用于生产实践。     

沾化凹陷南斜坡油气运移条件及运移特征研究

油气运移的条件和油气运移的特征决定了油气藏的形成与分布。沾化凹陷南斜坡不整合面、断层以及各层系储集砂体的空间配置构成复杂的立体网络通道，决定了油气的运移，控制了油气分布。以断层为垂向运移通道的油气藏常在断层带附近多层叠置；以连通砂体为主要运移通道的油气藏常形成于距烃源层较近或相邻的层位；以不整合面作为运移通道往往可使油气长距离运移形成各种地层油气藏。沾化凹陷南斜坡的油气藏都是油气经过两种或多种输导层阶梯式运移而形成的。砂体、断层和不整合面组成的输导系统的末端和边缘是油气运移的重要指向区。     

Effects of Process Conditions on Desalting and Demetalization of Crude Oil

The efficiency of desalting for six crude oils was studied with a SY-1 dynamic simulation experimental installation. The demulsifier DC2 was examined for 1#, 2#, and 4# crude oil and DC4 was used for 3#, 5#, and 6# crude oil. The effects of temperature, electric field gradient, dosage of demulsifier, and washing water on the desalting efficiency of six crude oils were investigated. The results showed that at the optimization process condition after desalting, the desalting efficiency and the salt content of 1# crude oil reached 89.17% and 1.92 mg/L; that of 2# crude oil reached 85.08% and 1.04 mg/L; that of 3# crude oil reached 91.06% and 1.35 mg/L; that of 4# crude oil reached 81.67% and 1.51 mg/L; that of 5# crude oil reached 81.03% and 2.32 mg/L; and that of 6# crude oil reached 86.64% and 2.67 mg/L. Different crude oils have different metal contents. Three assistants, ammonium nitrate (TJ1), nitric acid (TJ3), and polyamine carboxylate (TJ4), were used to improve the efficiencies of desalting and demetalization of six crude oils. TJ4 was more efficient in removing calcium and iron for 1# and 2# crude oil. TJ1 was more efficient in desalting and demetalizing 5# crude oil. The efficiencies for removal of calcium, iron, nickel, and vanadium respectively reached 99.89%, 98.33%, 20.58%, and 43.02%. TJ3 has better efficiency desalting and demetalizing for 6# crude oil. With the concentration of TJ3 increasing from 0 to 80 mg/L, the desalting efficiency increases from 31.22% to 73.54%, and the iron removal efficiency increases from 56.0% to 74.05%.

Frames of Reference in Mobile Augmented Reality Displays.

In 3 experiments, the authors investigated spatial updating in augmented reality environments. Participants learned locations of virtual objects on the physical floor. They were turned to appropriate facing directions while blindfolded before making pointing judgments (e.g., "Imagine you are facing X. Point to Y"). Experiments manipulated the angular difference between the learning heading and the imagined heading and between the actual heading and the imagined heading. The effect of actual-imagined on pointing latency was observed for naive users but not for users with brief training or instructions concerning the fact that objects can move with body movements. The results indicated that naive users used an environment-stabilized reference frame to access information arrays, but with experience and instruction the nature of the representation changed from an environment stabilized to a body stabilized reference frame.
