双轴晶体主平面上倍频的相位匹配

从折射率椭球方程和折射率椭球面出发，讨论光束在双轴晶体中传播及偏振的特性、主平面倍频共线相位匹配（PM）问题，得到了双轴晶体主平面内激光所有可能PM倍频的8种偏振组合及其相应的PM角公式、有效非线性（NL）系数deff的一般表达式。结果表明：得到的公式简单，可大大简化PM参数计算及优化设计；折射率椭球面是单层曲面，比双层的折射率面简单；基于折射率椭球面寻找所有可能PM的类型、偏振组合的方法物理图像简明，易于理解，大大降低了双轴晶体PM问题分析的难度。     

紫坪铺水电站AGC的设计与实现

本文首先介绍自动发电控制的基本原理和基本功能，然后介绍紫坪铺电厂AGC程序基本功能。作为水利枢纽工程，紫坪铺电厂的AGC有自身的特点，如电调服从水调，在保证下游供水的条件下实现自动发电控制，限制功率调节速度等，所以在实际运行中碰到许多特殊问题。为保证AGC功能的正常实现，采用一些特殊的方法解决以上问题。如通过设置最小下泄流量保证下游供水，限制功率调节步长解决功率变化过大等问题。通过试验。紫坪铺电厂在保证下游供水的前提下，顺利实现AGC各项功能，为作为水利枢纽工程的电站实现AGC提供了宝贵的经验。

Seismic Physical Modeling Technology and Its Applications

1. Introduction Seismic physical modeling technology is an important method for the research on seismic exploration theory and methods. In seismic physical experiments, the earth, mantle or field site are scaled down to physical models according to the similarity principle, and then the seismic field and its variation are observed in the laboratory for the research work on the theories and methods of the earth structure, earthquake forecasting, energy and mineral resource exploration, and engi…     

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.

Standardizing signs on bublic information in the New Coastal Area

The public information signs ( The term public information signs will be abbreviated to public signs in the following text.)in the urban areas not only offer convenience for people to move around, but also reflect the level of development and progress of those areas. It is essential to the creative development and uplifting of the New Costal Area (thereafter, NCA) to have a good understanding of its present situation with regard to its public signs, to discuss the related issues in the development, to work out a system that is up to international standard and develop its own standards in the course of implementing the national strategies on standardizing public signs.     

长庆油田陕北区原油破乳剂的筛选和复配

实验考察了8种市售水溶性破乳荆对长庆油田陕北区有代表性的宝塔区、安塞和子长原油(均为低硫中间基-石蜡基原油)的脱水效果(加量100mg／L，脱水温度55℃，时间3h)。目前长庆采油一厂使用的YT-100和延炼集团使用的GT-940对这3种原油的脱水效果均较好，但对子长原油的脱水率不高，分别为69．7％和58．9％。在由所选性能较好的破乳刺组成的4种二元复配物中，GT-940 HQ96-1对3种原油的脱水效果均高于单剂，最佳配比分别为4：1，4：1，3：2；其余3种复配物则对原油有选择性，其中GT-940 YT-100相近(97．5％)；YT-100 HQ96-1仅能改善子长原油的脱水效果，配比为4：1时脱水率最高(76．4％)；SP-169 HQ96-1仅能改善宝塔区原油的脱水效果．配比3：2和2：3时脱水率最高(92．9％)。表5参6。     

沉积环境与多元统计综合分析法

本文首先根据地震资料提取了十二种地震参数，然后通过对ＬＨ油田ＴＺ地区沙三上段下部地层进行沉积环境分析，确定了可能存在的沉积相类型，并用有序样品聚类的方法对过井和井旁地震测线按沉积相个数进行分割，由此而建立了该区各类沉积相的判别函数。通过这些判别函数，用逐步判别分析的方法，对该区其它地震测线的参数进行判别分类，最后搞清了研究区目的层的沉积相展布。通过分析和计算证明，这一方法对有地震资料的盆地或地区进行沉积相的划分，是行之有效的
