In this paper,starting with the concept of risk,trying to take the theory of probability,central limit theorem,definition of optimal statistic estimate and economic theory as the basis and according to the concrete situation of the natural gas exploration project,the formula to quantitatively determine the risk is derived.

文章从"风险"的概念入手，尝试以概率论、中心极限定理、最优统计估计量的定义和经济理论为基础，结合天然气勘探项目的具体情况，推导出了定量测定风险的公式。

By taking advantage of a corollary of the Desargues theorem and the corresponging extension of Desarguesian configuration, the concept of stereohomology has been defined in projective geometry and presented based on homogeneous coordinates. Consequently, a series of geometrical transformations, such as central projection, parallel projection, centrosymmetry, translation transformation, reflection, rotation transformation, which can be contained in it or derived from it have also been analytically defined.

利用Desargues定理的一个推论和引申的Desargues图形，给出"空间透射"在射影几何意义下基于齐次坐标表象的解析定义，从而解析定义了可蕴涵其中的中心投影、平行投影、中心对称、平移、反射等几何变换以及可由此衍生出的旋转变换。

Chain index An index number derived by relating the value at any given period to the value in the previous period rather than to a fixed base.

环比指数指通过把某一时期的数值与前一时期的数值相比，而不是与固定基期相比而得出的指数。

The definition and stability criterion of resonant operating points in a CPT system have been described. A Poincarémapping model has been built up and its Jacobian matrix has been derived with the implicit function derivative rule and chain rule. Then the stability of the fixed points can be determined according to the eigenvalues of the the Jacobian matrix. It has been used to study an example push-pull CPT system with three resonant operating points.
