| 中文摘要: |
| 测定了剑状矛蚌( Lanceolaria gladiola )在不同温度和不同pH条件下的滤水率。结果表明,在不同温度(10~28℃)条件下,剑状矛蚌的滤水率均随温度升高而上升,达到最大值后呈下降趋势,其中滤水率最大值出现在24℃时,大、中、小个体组剑状矛蚌滤水率最大值分别为0.826 L/h、0.768 L/h和0.653 L/h。在同一温度下,个体滤水率随软体部干重的增大而增加。温度、软体部干重、温度与软体部干重的交互作用对剑状矛蚌的滤水率有显著影响( P ＜0.01)。在不同pH梯度上,剑状矛蚌的滤水率呈一个明显的峰值变化,其峰值出现在pH=8,大、中、小个体组的滤水率分别为0.832 L/h、0.604 L/h、0.421 L/h。在pH 6~7之间,中个体组、小个体组个体滤水率呈平缓变化。pH、软体部干重及其交互作用对剑状矛蚌的滤水率均有极显著影响( P ＜0.01)。 |

| The study determined the filtration rate of Lanceolaria gladiola at different temperatures and pH. The results showed that under the range of 10 to 28℃, the filtration rate of L.gladiola gradually increased with the increasing of temperature, which reached the maximum at 24℃, and then began to decrease. The maximal filtration rate of large, medium and small-sized L.gladiola was 0.826 L/h, 0.768 L/h and 0.653 L/h respectively. At the same temperature,the filtration rates increased with the increasing of the weight of soft part. Temperature, weight of soft part and the interaction between temperature and weight of soft part have significant effect on the filtration rate of L.gladiola ( P ＜0.01). Under different pH grades, the peak value of filtration rate of L.gladiola showed an apparent change. At the pH of 8, the value reached the maximum. The filtration rates for large, medium and small-sized L.gladiola were 0.832 L/h、0.604 L/h、0.421 L/h respectively. When pH was between 6 and 7, the filtration rates for medium and small-sized L.gladiola changed smoothly. Weight of soft part and the interaction between pH and weight of soft part have significant effect on the filtration rate of L.gladiola ( P ＜0.01). |
