It is the change that virtual technology gives birth to a great influence on the human's cognitive activities. First of all, virtual technology has caused obvious change of cognitive relation between subject and object, which includes the change of interaction between subject and object, digitization of cognitive resonance and scene of cognitive model, etc. secondly, virtual technology has improved the subject's cognitive ability and level: the ability of esthesia of the subject has been strengthened, the change of the cognitive structure and the way to obtain information of the subject has been caused and the regulation and control ability of the subject has been improved by virtual technology.

正是这种转向使得虚拟技术对于人类的认识活动产生了重大影响：首先，虚拟技术导致了主客体之间的认识关系发生明显的变化，主要包括主客体作用的方式的变化、认识中介的数字化以及认知模型的情景化等；虚拟技术提高了主体认识能力和水平：虚拟技术增强了主体的感知能力，引起了主体认识结构的变化，认识主体获取信息的方式发生了变革，提高了主体对认识活动的调控能力，张扬了主体在认识活动中的能动性与创造性；虚拟技术拓展了主体的认识领域，即它扩展了主体的认识空间、丰富了主体的认识来源。

Since 1996, the Rice Research Institute of Liaoning Province has laid stress on the genetic improvement of stigma exsertion rate of japonica male sterile lines. By introducing the genes of high stigma exsertion rate from indica into japonica, a group of japonica male sterile lines with high stigma exsertion rate have been successfully developed. Their stigma exsertion rate have been greatly increased from less than 30% to more than 80%, resulting in an increased outcrossing rate over 60% and a high seed production yield of 3.0~4.5 t/hm^2. Moreover, using these sterile lines, a group of new japonica hybrid rice combinations such as Liaoyou 5218 (Liao 5216A/C418), Liaoyou 1052 (Liao 105A/C52) have been developed and released to commercial production.

自1996年以来，辽宁省稻作研究所加强了粳稻不育系的柱头外露率遗传改良研究，通过导入籼稻的高柱头外露率基因，选育了一批高柱头外露率的粳型不育系，柱头外露率由原来的30%以下逐步提高到80%以上，异交结实率可达到60%以上，杂交制种产量可提高到3.0~4.5t/hm^2，并配组育成了辽优5218（辽5216A/C418）、辽优1052（辽105A/C52）等杂交粳稻新组合，在生产上得到了大面积推广应用。

Through detailed analyzing some influencing factiors of sand liquefaction, seven parameters were selected as assessment indexes. They are earthquake magnitude, peak ground surface acceleration, standard penetration value, specific penetration resistance, relative compaction, average particle diameter, and water table. The extension assessment model has been established that was applied to assessment of sand liquefaction potential. The model had been trained by the historical data and has been assessed in virtue of sand liquefaction from the historical data by simulating, and got a excellent result. After introduction of the support vector machine theory, this paper established the assessment model of sand liquefaction based on the support vector machine, and assessed in sand liquefaction from virtue data of some fields in home and overseas with the tool Libsvm, which was programmed based on the support vector machine theory. And got a good coherency between the assessement results and the actual liquefaction.

在详细分析影响砂土液化因素的基础上，选取了震级M、地面最大加速度g_、标准贯入击数N_(63.5)、比贯入阻力P_s、相对密实度D_r、平均粒径D_(50)、地下水位d_w等7个参数作为评价指标，建立了砂土液化势的可拓评价模型，并对历史数据进行仿真评价，取得了较好的应用效果；在对支持向量机的理论进行介绍后，本文建立了基于支持向量机的砂土液化势评价模型，并利用在基于支持向量机理论的Libsvm软件，对若干国内外场地的现场实测数据进行了评价，评价结果与现场表现基本上一致。
