查询词典 fluctuation

In some conditions the fluctuation of stock price is not a continuous process,in order to imitate and analyze the uncontinuous process,a cusp catastrophe model of stock price is set up,in the mean time makes a brief analysis of this model,and finally gives some advices according to the analysis.

针对股票价格变化在某种条件下具有不连续性的问题，对这种不连续的股票价格变化进行了描述与分析。以突变理论为基础，建立了一个描述股票价格短期变化过程的尖点突变模型，并对该模型进行了简要分析。最后，根据分析结果提出了相应的政策建议

The results indicate that the deviation of viscosity concentration is still not acceptable for most of the pigments, although the solid content of pigment slurry is well linear with the reciprocal of the square root of viscosity. Furthermore, the slight fluctuation of solid content which is close to the viscosity concentration can cause significant variation of the low shear viscosity according to the calculation, and result in the uncredible test value of viscosity concentration.

结果表明，尽管颜料悬浮液固含量与黏度平方根倒数的线性关系相当好，但对于相当一部分颜料，由此得到的黏浓度数据偏差仍然不可接受；而且根据测算，在黏浓度点附近，固含量的微小波动会造成低剪切黏度很大的变化，导致黏浓度的测定结果不可靠。
