Firstly, we put forward twoways to reconstruct the correlation curve accordingto whether the changed correlation peak. After analyzing the character of the correlation curve,we find the method to judge whether the peak is excurved. Secondly, the confirmation of thecomplex signal and difference value curve, according to the present optimized arithmetics.

In the long time creep tests, by regressive analyses, the creep curve of glauberite at different stress level is obtained: at 50% of its compressive strength, the creep curve is ε 0.009t0.3265, at 80% of compressive strength, the creep curve is ε=0.0098ln-0.0014. It is clear from the creep curves of the rock mass, that the creep rate at high stress level is higher than that at the lower stress level.

通过长时间的蠕变实验，回归出钙芒硝盐岩蠕变在不同应力水平下随时间变化的曲线，其抗压强度50%时的曲线方程为ε=0.0098ln-0.0014，抗压强度80%时的蠕变曲线方程为ε=0.012ln-0.0056，应力水平高时其蠕变速率高于低应力水平的蠕变速率。

Results showed diural variations of leaf Pn displayed bipeaked curve model, indicating the depression of photosynthesis at noon. Leaf Pn rate in June was higher than in September; Compared to leaf Pn, Cs had a similar changing curve, Cs in June was higher than in September. While diural variations of intercellular CO2 concentration were opposite to that of leaf Pn and Cs, decreased before 1200,increased after 1200, decreased again at 1600,after 1600 increased again; diural variations of climatic factors displayed single peaked curve model, peakedvalue occurred at 1400,and their influences on physiological factors were indirected and integrated.

However , the demand curve derived in this way may slope either downward or upward the supply curve derived in this way even doesn 't exist in the monopolistic situation theoretically , if a supply curve doesn 't exist to a monopolistic producer , there are no such supply curves existing to oligopolistic and monopolistically competitive producers either .

然而这样推得的需求曲线既可能向下倾斜，也可能向上倾斜；这样推得的供给曲线，在垄断情况下就&不复存在了&；而且理论上讲，如果垄断厂商没有供给曲线，那么寡头厂商，垄断竞争厂商也会没有供给曲线。
