Making use of structural characteristics of the Lower Latitude Meridian Circle and the error theory of this instrument, we have developed a method used to measure directly instantaneous atmospheric refraction, and moreover built a local observational astronomical refraction model toward the east, south, west and north of Yunnan observatory that is classified according to the star's spectral type.

阐述了云南天文台探讨出的利用低纬子午环的观测原理，在不同方向和不同天顶距直接测定瞬时大气折射值的一套方法，并给出了用实测数据在东、南、西、北4个方向建立的按恒星光谱型分类的大气折射实测模型。

In non-lack-of-money market situation, you should not measure the market being overoptimistic.

在这个&不缺钱&行情下，不要轻易去&言顶&，也不要再用适应牛市行情的分析工具去丈量，收盘时，大盘72周期线位于3377点，144周期线位于3378点，两线黏合在一起形成对短期的强力支撑。

Fuller invented the Geodesic dome coined the term synergetics, a "Geometry of Thinking," a metaphoric language for communicating experiences using geometric concepts, long before the term synergy became popular.

福勒发明了多面体球顶，创造了&协同几何学&这一词汇，提出&几何学的思维&，开创了用几何学的概念、使用隐喻语言沟通经验；很长时间以后，&协同&这一词语才流行起来。

According to the distribution law of three zones in uncovering coal and the relation between the distribution law and delay outburst, the prevention and control technology is brought up, which firstly adopts gas drainage in the coal through drainage hole to release the outburst power by stages, and then intensifies the intensity of uncovering coal and increases the length of stress relaxation zone and stress concentration zone by using the liquid injecting and freezing to prevent the coal rheology. At last, the shoring measures to prevent roof falling is tabled.

根据掘进工作面附近暴露煤体的&三区&分布规律及其与延时突出的关系；提出先采用钻孔抽放石门突出煤层瓦斯等措施分阶段释放煤与瓦斯突出动力源；再用注液冻结技术增强揭开煤体的强度、增加集中应力区和卸压区的长度来防止被揭开煤体发生流变而导致延时突出的防突技术；以及在揭煤后采取迅速支护防止空顶和冒落等防治措施。
