But ECT technology has the following characteristics: 1 the measured capacitance and its change induced by the measured material concentration variation are very small, but the stray capacitances of co-axial screening cable and CMOS switches are relative very large, so the capacitance detecting is easily affected by the stray capacitances, 2 the electric fields in the sensors detecting region is affected by the permittivity distribution, non-uniformity of the space responsive sensitivity is very high, and the image reconstruction is undetermined.

但由于ECT技术中，首先所检测的微电容量及其因物流相含率的变化所引起的变化量很小，而由相关的连接同轴屏蔽电缆与切换CMOS开关所引入的杂散电容远远大于测量电容，微电容的测量容易受杂散电容等的影响；其次，多电极电容传感器测量区内的电场受介质分布的影响，且测量区内的空间响应灵敏度极不均衡，其影响图像重建的不确定性；其三，ECT中的图像重建，由于其是一个欠定问题的求解，在迭代求解方法中，迭代的初值影响迭代过程收敛到近似解的速度；其四，对于气/固两相流应用而言，由于ECT系统在线标定的难以实现，管壁磨损等因素的影响制约该技术应用于生产工艺中气/固两相流的长期连续检测。

The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.
