This paper presents the analytical results of solar MgⅠb_(2)flash spectra,obtained by the prototype Fiber Arrayed Solar Optic Telescope in process of the 2013 Gabon total solar *** analysis reveals irregular distributions of the spectral line parameters like ratio of line source function to continuum oneβ,ratio of line emissivity to continuum emissivityζ,ratio of the continuum opacity to the line opacity r_(0),line center optical depthτ_(0)、,the line widthΔλ_(D),and the line-of-sight velocity v_(los),while the approximately spherical symmetry can be found in the maps of integrated line intensity and continuum *** irregular distributions originate from those of line profile features like the maximum intensity,the line width and line center *** is also found from the recovered line center optical depthτ_(0) that in the middle chromosphere,the optical depth is not small due to nonignorable absorption and the long light path along the ***,we show that the excessive broadening of spectral lines can be due to co-existence of multiple radiative sources with different line-of-sight velocities unresolved in one detector pixel.

Optical observations from a ground-based astrometric instrument provide a unique set of data sensi- tive to variations of local plumb line, which represent the change of local gravitational field on the ground. The local gravitational change could be caused by density variation or movement of underground mass in addition to tidal action. Earthquake was found to be related with gravitational change. A seismic zone could have abnor- mal underground material density, causing the variation of plume line on the ground. In this frame, the astro- metric telescope can measure the variation of local plumb line by observing the local astronomical longitudes and latitudes from stars in the Hipparcos catalog. In this study, we estimate the deflection angle of the plumb line on a ground site, and give a relation be- tween the angle, abnormal mass and site distance （depth and horizontal distance）. Then we derive the abnor- mality of underground material density using the plumb lines measured at different sites, and study the earth- quake gestation, development and occurrence. Using the deflection angles of plumb lines observed at two sites, we give a method to calculate the mass and the center of gravity of underground materials. We also esti- mate the abnormal masses of latent seismic zones with different energy, using thermodynamic relations, and in- troduce a new optical astrometric instrument we had developed.

The reactivity of ferro-coke is much higher than the conventional coke and its application to the blast furnace is expected to improve the blast furnace reactions efficiency and to reduce fuel consumption and ***-coke could thus be a new kind of BF burden materials with broad development *** order to under the effect of using ferro-coke on BF reactions,a series of laboratory tests has been conducted in this ***,ferro-cokes were made in a laboratory cokemaking oven of chamber type by adding three kinds of iron ores into the cokemaking coal blend and the ferro-cokes with higher reactivity as well as comparatively high strength after reaction were chosen as experimental samples for the further ***,the carbon solution loss reaction tests,the coupled reactions tests between iron ore reduction and ferro-coke gasification,and the primary slag formation tests under the condition of ferro-coke and iron ores mixed charging and simulating blast furnace conditions were carried *** experimental results showed the gasification reaction beginning temperature of ferro-coke is obviously lower than that of the conventional coke,that ferro-coke mixed charging is more effective than nut coke mixed charging in terms of accelerating iron ore reduction,and that ferro-coke mixed charging can decrease the melt-down temperature as well as the pressure drop of stock column and narrow down the softening-melting range,which are beneficial to the improvement of blast furnace performance.

作为1m太阳望远镜(NVST)导行系统的重要组成部分,导行镜的成像稳定性至关重要。环境温度载荷造成的镜体变形会造成热离焦从而影响导行镜的成像质量。采用有限元方法分析NVST导行镜在-5℃、20℃和35℃等不同环境温度状态下的温度分布,并计算了温度变化产生的轴向结构变形,即最大离焦量为6.45μm。计算结果表明:主镜到靶面的距离变化最大值常温下为7.14μm远小于系统焦深(±35μm),达到了对NVST导行镜无热化结构设计的目的。
