For the creation of virtual objects and virtual environments, we will study the construct of an authoring system which includes environment definition and environment management, so that the properties of autonomy, interaction and presence can be properly defined and realized.

在建构方面将研究适当的描述系统以便描述虚拟环境及虚拟物件并使其具有自主、互动及实存之特性。

STEP (ISO 10303) described product model information for life cycle. It was the base of the product data exchange, but there was lack of advanced semantic express.

基於STEP标准对产品全生命周期信息进行规范化描述，是产品信息交换的基础，但高层次语义描述能力较弱。

First, the formal representation of the search environment is established, the multi-UAV is modeled as a controlled system and the predictive model of the system is presented. Considering the uncertainty of the sensor measurement and the environment, a Search Probability Map is defined and the updating method based on Bayes formula is presented. Based on SPM, information gain is defined to measure the search effects and used to be the optimization object in the predictive horizon. By using of GA, the solution of the optimization problem is got and it is taken as the input of the controlled system.

首先，建立搜索环境的规则描述，然后将多个UAV建模为一个控制系统，建立系统的预测模型，考虑到UAV传感器测量的不确定性和环境自身的不确定性，建立搜索概率图描述搜索环境的不确定性，给出了基于Bayes准则的搜索概率图更新方法，继而基于搜索概率图定义信息增益来衡量搜索效果，并将预测周期内的优化目标定为最大化信息增益，采用遗传算法进行求解，得到最优解作为被控系统的输入。

When investors are in the treasury secondary market, they have to undertake two kinds of risks: the first one is yield risk, that is, return of investment is lower than inflation rate. This risk can be depicted as the deviation between the ROI and the inflation rate. Secondly, fluctuation risk in the treasury secondary market, that is, the uncertain fluctuation risk may be bullish or bearish in the treasury market.This risk can be depicted as the square deviation of the treasury price in the secondary market.

在国债现货二级市场上的投资者，要承担的风险主要有两种：第一种风险是收益率风险，也就是投资收益率可能低于通货膨胀率的风险，这种风险可以用与通货膨胀率相比较的差值的大小来描述；第二种风险是二级市场价格波动性风险，也就是市场价格上、下波动的不确定性风险，这种风险可以用二级市场价格的标准差来描述。
