| 6. | The results indicate that there is especially a narrow rang of phase difference in which the amplitude of subharmonic waves is notably diminished and that the diminishment is affected by initial amplitudes of the waves
结果表明，有一个狭窄的相位差范围，当相位差的值落入其中时，亚谐波的空间演化受到显著的削弱；而且，相位差的这种影响受基波及亚谐波初始幅值的制约。 |
| 7. | According to analyzing how the factor ( example : water temoerature ) which continuously changes influence the addition quantity of coagulant , we found the addition quantity did not change in a narrow range of the temperature , so we give a data in every range of the temperature , and we regard it as a constant in every range . at the same time , we found the factors ( example : alkalinity , ph of the raw water ) change always in a narrow rang , and we regard it as a constant too
同时对那些常年在一个很小范围内变化，在个别较短时间段内，变化幅度较大的影响加药量的因素(例如，碱度、 ph值) ，我们可以将这些因素在小范围内变化时，作为常量处理，当这些变量在很短时间段内(这些变量常年稳定)有较大的变化时，我们可以加入试剂，调整这些因素值的大小，使它们处于正常的范围内，这样也可以将它们作为常量处理。 |
