Consequently, this essay choose the "Z-Score Model", which was developed by Altaian, the famous American expert in risks management, to analyze and evaluate the listed companies' credit risks in China and to verify its efficiency to Chinese stocks market. The " Z-Score Model" is an innovation in the evaluation of companies' credit risk in the United States' banks, which is now being used widely. If the model is also applicable in Chinese stocks market, it will be significant in both theories and practices.

因此，本文选用作为美国商业银行信用评估方法的一次重要创新的，目前仍被美国商业银行广泛使用的，由美国著名信用风险管理专家Altman建立的"Z评分模型"(Z-Score Model)来对我国上市公司的信用风险状况进行实证研究，验证其在我国股票市场的有效性程度，如果能证明"Z评分模型"同样适用于我国证券市场，并将其改造为更适合我国上市公司的信用风险分析模型，将不仅具有很大的理论价值，而且也具有十分重要的现实意义。

As applications, we prove the following results: If / has pointwise pseudo-orbit tracing property, for any k ∈ Z+, and fk is chain transitive, then for any k ∈ Z+, fk has open set transitive ; If f has pointwise pseudo-orbit tracing property, and for any n ∈ Z+,fn is chain transitive, then f has sensitive dependence on initial conditions; If f is open set mixing and has pointwise pseudo-orbit tracing property, then f has property P; Let f :→ be a homeomophism, then f is pointwise pseudo-orbit tracing property if and only if the shift map σf is pointwise pseudo-orbit tracing property.

作为应用，证明如下结论：若f具有逐点伪轨跟踪性质，且对任意k∈Z+，fk为链转换的，那么对任意k∈Z+，fk为开集转换；若f具有逐点伪轨跟踪性质，且对任意n∈Z+，fn为链转换的，则f具有初始敏感依赖性质；若f为开集混合的，且具有逐点伪轨跟踪性质，那么f具有性质P；设f：→是同胚映射，那么f具有逐点伪轨跟踪性质当且仅当移位映射σf具有逐点伪轨跟踪性质。

:at any point of elastic object ,the rotating value of z axis is :ν u θz = substitute get:ν= u = y x θz = 0 x y into the formula , we can Similarly:θx = 0 θy = 0 So the rotating values of the three coordinates at any point of the elastic object are zero.

：在弹性体的任一点处，该点对z 轴的旋转量ν u θz = x y u =ν=将代入，可得： y x θz = 0 同理θx = 0 θy = 0 即弹性体的任一点对三个坐标的旋转量都等于零。
