ASTM D2896-03 Standard Test Method for Base Number(BN) of Petroleum Products by Potentiometric Perchloric Acid Titration. 电位高氯酸滴定法对石油产品碱值的试验方法。
If you wish to ensure that Planning only calculates using the base number with a given number of decimal places, then the @ TRound built in function may be used to achieve this. 如果您想要确保Planning仅使用有给定小数位的基数(BN)进行计算,那么内置在函数中的@TRound可以实现这一点。
It was recognized that the retention percentage of total base number and the sludge amount could reflect the hydrolytic stability. 探讨了评价高碱值磺酸钙水解安定性的方法,认为总碱值保留值和淤渣量均能较好地反映水解安定性。
The Total Base Number(BN) ( TBN ) can be described as a measure of oil ′ s ability to neutralise strong acids created during the combustion process. 总碱值(TBN)可以说是润滑油中和燃烧过程中产生的强酸的重要手段。
A logarithm tells you what power a base number must be raised to in order to produce a given value. 对数说明一个底数的几次幂等于一个给定的值。
