The results show that the peak tension in the conductor of upper crossarm at suspension point exceeds the design value. Insulator rupture has no effect on tower component of upper crossarm, but it has significant influence on insulator tension of upper crossarm. The lower limit of longitudinal unbalanced tension of two and more than two bundle conductor is relatively small. Insulator rupture should be taken into account in the design for overhead transmission lines.

分析结果表明，上横担一组绝缘子破坏失效后，破坏档未破坏端导线的张力超过了技术规程中的设计值；导线的跌落对破坏档未破坏端的上横担绝缘子受力有较大的影响，而对上横担铁塔杆件没有明显的影响；考虑杆塔断线荷载时，应增大两分裂以上导线纵向不平衡张力的下限值；在架空送电线路的设计中应该考虑绝缘子断裂的荷载工况。

However, serious problems occurred at the same time, such as the transportation in scenic spot, security affairs, the crowdedness during peak period, the reception and management, etc. Confronting with these problems, we had no time to delay. It was urgent to find methods for the balance of development and protection.

The results indicated, that the curves of hatching rate and normal diploid larva output showed a single peak, with the highest point at 3.4 τ0, corresponding to metaphase of the first mitotic division, the results were obtained irrespective of the different pre-treatment water temperatures, thus confirming the veracity of measuring heat-shock timing by τ0 and the wild applicability of this method in cyprinid and also suggesting a new way to the operations of induced gynogenesis in related fish.

结果提示了以τ0单位度量热休克处理时机的准确性以及该优化方法在鲤科鱼类雌核诱导操作中的通用性，从而为相关鱼类的雌核发育操作提供了有价值的资料。

The positive expression of Slit2 located in the cytoplast on oligodendrocyte and astrocyte.The positive cells were found at 3d after spinal cord injury, reached peak on 7d after injury, declining after 14d. The change of Slit2 was correlative with the rehabilitation and regeneration of the axon on the forepart period.

免疫组织化学检测：Slit2蛋白定位于星型胶质细胞和少突胶质细胞的胞浆，呈棕黄色染色，于脊髓损伤后第3 d出现，阳性细胞逐渐增多，于脊髓损伤后第7 d，Slit2阳性表达的细胞数达到高峰并趋于稳定，伤后第14 d开始逐渐下降，呈一过性增高。

A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化；回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题；发现太阳活动可能存在36a左右的周期；证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在，指出这一时期的宇宙成因同位素峰值事件具有全球性，弱的太阳活动和弱的地磁场是这一事件发生的原因所在；揭示出古里雅冰芯记录到的"8.2ka BP事件"，认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关；发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化，而全新世气候变化大致与太阳辐射变化同步；发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征，同时还具有南半球气候变化的某些特征，这说明热带地区可能对全球气候存在重要的影响。
