Analysis of Meteorological Conditions of Freeze Damage to Citrus in Southern Shaanxi in the Winter of 2010 and Defensive Countermeasures

In order to take advantage of the climate resources more effectively ac- cording to the local circumstances and to plan and develop the citrus industry in Southern Shaanxi more reasonably. On the basis of the investigation of freeze dam- age to citrus occurring in Southern Shaanxi in the winter of 2010, the climatic back- ground for the formation of this freeze damage was analyzed. In combination with the freeze damage indicators during the overwintering period and the harmful accu- mulated cold during the cold wave, indexes for grading the freeze damage in southern Shaanxi were analyzed and verified, and the perspective of grading the freeze damage using the harmful accumulated cold during the cold wave was also presented. Through analyzing the extremely lowest temperature and the harmful ac- cumulated cold in the winter of 2010 and in history at 12 citrus growing counties （districts） in Ankang area and Hanzhong area, the reasons why the freeze damage to citrus during the overwintering period was severer in the west than in the east of Southern Shaanxi were discussed, and the results obtained were basically consistent with the actual situation observed from investigation. Finally, defensive countermea- sures against the freeze damage to citrus during the overwintering period were put forward from several aspects.

论我国引入公司章程防御性条款的制度构造

基于限制控制股东滥用资本多数决和强化公司章程自治以保护特定股东利益的需要,英国《2006年公司法》确立的防御性条款制度值得我国借鉴。防御性条款的"防御"对象包括控制股东与公司管理层,在没有控制股东的公司中也可包括特定股东。我国《公司法》中的防御性条款可以划分成两大类:实体型防御性条款与程序型防御性条款。防御性条款的制定与修改原则上都要求全体股东一致同意。我国《公司法》确立防御性条款法律制度时,应建立防御性条款的特别告知与警示制度。在修订《公司法》时,引入防御性条款法律制度可通过概括性条款或具体规定的模式来进行。

美军空袭兵器及作战手段研究

针对陆军防空旅装备体系研究所需防御对象,以美军空袭兵器的作战手段、类别及装备数量、威胁分析为主要研究对象,采取无遗漏统计法结合所掌握的知识有针对性地进行分析与研究。以双方兵器的性能特点为基石,分析了全然防御对象与非全然防御对象、重点防御对象与辅助防御对象,以及陆军防空旅装备体系研究所需防御对象的必要参数。通过分析,为下一步开展陆军防空旅装备体系的研究提供精确的防御对象参数与等级划分理论。
