「ｐＨベクトル係数Ｋ値」
図４は、表１を利用しｘ軸に１０ ^ΔｐＨをｙ軸にΔＳＣ値を取り、単位ｐＨ当たりのＳＣ値の変化率Ｋ値（図における傾き）を求める図である。Ｋ値は図５のＳＣ検量線の勾配と同じ大きさを持つが符号が異なる。図４からＫ＝Ｋ_１＝１８．８ｍＡ／ｐＨ、Ｒ^２＝０．９９１３を得た。Ｋ値は目標ＳＣ値をＩｓ＝σＥ_０としてＰＡＣの自動注入実験からも求める事が出来るが表１から求める方が、測定精度は良く、相関係数０．９９１を得ることができた。 "PH vector coefficient K value"
FIG. 4 is a diagram for obtaining the change rate K value (slope in the figure) of the SC value per unit pH by using Table 1 and taking 10 ^ΔpH on the x axis and ΔSC value on the y axis. The K value has the same magnitude as the gradient of the SC calibration curve in FIG. From FIG. 4, K = K ₁ = 18.8 mA / pH and R ² = 0.9913 were obtained. The K value can also be obtained from the PAC automatic injection experiment with the target SC value Is = σE ₀ , but the measurement accuracy is better and the correlation coefficient of 0.991 can be obtained from Table 1.

さらに、この３個の注入率の回帰分析から全ての導電率を満足する設定電位Ｅ_０＝−０．４４７ｍＶの演算ＰＡＣ注入率を与える式（９．１）を図１０より得る。
ＰＡＣｓｐ＝ＰＡＣ_４＝１７１．５Ｅ＋９９．４，Ｒ^２＝１・・・・・（９．１） Further, from the regression analysis of the three injection rates, an equation (9.1) that gives the calculated PAC injection rate of the set potential E ₀ = −0.447 mV that satisfies all the electrical conductivity is obtained from FIG.
PACsp = PAC ₄ = 1 71.5 E + 9 9.4 , R ² = 1 (9.1)
