2.2 赤潮发生池pH值的变化规律赤潮发生池35号池pH值和对照池34号pH值的日变化都不明显,但35号池pH值最高为9.O,最低为8.7,而34号池pH值最高为8.5,最低为8.2。35号池pH值平均比34号池高出O.44(见表1和表2)。经t检验,35号池pH值与34号池pH值有显著性差异(P<0.01)。从图3可以看出,随着赤潮的衰落,35号池的pH也逐步降低,35号池的最高pH值为8.7,平均为8.60;34号池的最高pH值为8.4,
2.2 Variation rules of pH value of red tide occurrence pool The pH value of No.35 pool of red tide occurrence pool and daily change of pH value of control cell No.34 are not obvious, but the highest pH value of No.31 pool is 9.O, the lowest is 8.7, The highest pH of the pond was 8.5 and the lowest was 8.2.35. The average pH of the pond was 0.44 higher than that of the 34th pond (see Tables 1 and 2). After t test, there was a significant difference between pH value of No.35 tank and pH value of No.34 tank (P <0.01). As can be seen from Figure 3, with the decline of red tide, the pH of the No. 35 pool is also gradually reduced, the maximum pH of the No. 35 pool is 8.7, with an average of 8.60; the highest pH of the No. 34 pool is 8.4,
