By means of constructional iterative equation , this paper presents a way to give out the existence and singularity of a type of equational root with gradual approach method 摘要本文通过构造迭代函数，利用逐次逼近的方法给出了一类方程根的存在性与唯一性的判断的一种解决方案。

During the calibration , a regress - analyse method is used to get the weight of the different channel based on equational coefficient , the weight represents the sensitivity of each channel 为了提高测量的可靠性和精确性,对9通道数据同时采集,在测试标定时采用回归分析方法,根据灵敏度得到不同通道的权值。

The intellectual drop that i feel chemical is very miscellaneous , what does everybody have to remember chemical knowledge dot and the wise move with equational chemistry excuse me ? withered first 化学死记的东西还是瞒多的,在理科里面.但是题目做的多了自然也就熟悉了,没必要去死记硬背的.学各科都一样,有很多方法和窍门的,要害是找到适合自己的那套方法
