  peak number
     A method including three indexes ( i.e . elasticity of peak number, homostasis of proportion among peaks and homostasis of peak area) was proposed to evaluate the performance of the measures on different aspects. According to the three proposed indexes, six different measures were evaluated with chemical fingerprints simulated by computer. The results indicated that cosine of the angle is much suitable for assessing the fluctuation of proportion between the peaks.

In this article, the shape, peak number and ratio of slow to fast in electrophoretic histogram, and range of cell electrophoretic mobilitybetween upper and lower zones were investigated for ascitic and spleen cells in four groups of normal and SRS ascitic tumor mice. Besides, observation between electrophoretic behaviour before and after treatment with anti-θ serum and E-rosette test were parallelly carried out for normal and SRS ascitic tumor mice. The results showed that the series of mouse SRS ascitic tumor was closely connected with T lymphocytes, but still contained other cells including B-cells.
