In this article a great deal of experimental data was examied and it was proved that the classical formula of a initial yiesld pressure had a error of ±9%(for open ends)to ±13%(for closed ends)in certain cases.The corrected formula in this article has a corresponding error of only ±5.4% to ±3%.Obviously,this formula has already fulfilled the requirement of designing.

The classical formula of confidence limits of inhibition rate (IR) would sometimes lead to contradictory conclusion with Student t-test, especially when the variation coefficent of the denominator of IR is large.In this paper, a new formula derived from Keller's method, is proposed for solving correct confidence limits of IR. The recommended example showed that both the new formula and Student t-test would reach the same conclusion whatever the variation coefficent of the denominator of IR...

The classical formula of confidence limits of inhibition rate (IR) would sometimes lead to contradictory conclusion with Student t-test, especially when the variation coefficent of the denominator of IR is large.In this paper, a new formula derived from Keller's method, is proposed for solving correct confidence limits of IR. The recommended example showed that both the new formula and Student t-test would reach the same conclusion whatever the variation coefficent of the denominator of IR is. thus, the author suggests that the new formula is more reliable as compared with the classical.

对衡量抑制生理或病理反应的药物,一般可用抑制率:IR=(x_1-x_2)/x_1。经典的抑制率可信限的近似公式当比数分母x_1的差异系数过大时,易得出假阳性结论。本文利用Fieller方法导出正确的抑制率可信限公式,获得的结论与两组均数比较的t检验保持一致。因此认为:当利用抑制率作数据处理时,为防止出现假阳性,以用本文介绍的可信限公式为宜。

Untill now there are no classical formula for computation the coefficient of dilution of water sample in the BOD-determination, only an empirical method has been used. Based on a large number of practices, we tried to solve this problem theoretically. The selection of the coefficient of dillution water sample will be reasonable if the comprehensive effects of the following factors are considered: the chemical oxygen demand(COD_(Cr)), the biochemical index(α=BOD_5/COD_(Cr)) and the quantity of dissolved oxygen(QDO), and the unused oxygen consuming quantity in dilution water(△W). The value of the biochemical water sample is between 0.72 to 0.25 approximately. Based on the characteristic parameter, referring to the allowable range of the biochemical oxygen demand on the fifth day(η), we can derive the general formula for computation the coefficient of dilution water sample as follows: C_n=(0.72×0.58~(-1)/(0.7WDO-△W))·COD_(Cr)+1-QDO/WDO This formula is very simple and convenient and may be used for various water samples. Its reliability have been proved by a large number of monitoring tests and experimental verifications. It was also described the particular applications of the formula.
