水蚤能适应很大范围的温度和溶解氧，但对溶液pH值有要求。

Daphnia could adapt to a wide range of temperature and dissolved oxygen of the water , whereas need proper pH value .

而灭活效果受pH值（在6.0~8.0之间）、剑水蚤密度、氨和氯的投加时间间隔影响较小。

Other factors , such as pH value ( between 6.0 and 8.0 ), concentration of Cyclops and the interval of adding of ammonia and chlorine , are of little influence on inactivation .

实验结果表明，随着重金属离子暴露时间的延长，中华哲水蚤T-SOD活性变化显著。

The results showed that the SOD activity changed markedly with prolonged exposure of these ions .

结果表明：PFU中的原生动物主要是纤毛虫，微型后生动物主要是轮虫和水蚤。

The results show that there are protozoa ( main infusorian ) and mini-metazoa ( rotifer and daphnia ) communities in PFU .

有机络合态的铜也能为大型水蚤所吸收和利用，在相同浓度条件下大型水蚤对腐殖酸络合态铜的利用大于EDTA络合态铜。

It 's also proved that copper complexes are bioavailable to Daphnia magna . Moreover , the bioavailability of copper complexed with humic acid is more than that with EDTA under the same concentrations .

Hg2+和pb2+对中华哲水蚤T-SOD活性的影响均表现为随暴露时间延长，呈先上升后下降的趋势。

Effects of Hg2 + and Pb2 + on the SOD activity were increased first and then decreased during prolonging the exposure time .

在12d的暴露过程中，镉或镍既可诱导日本虎斑猛水蚤MT的合成，也可表现为抑制效应，即MT的变化与暴露剂量和时间均有相关性。

During the 12 d exposure , heavy metal ( Cd or Ni ) not only induced the synthesis of MT in the copepod T. japonicus , but also displayed the inhibition-effect , i.e. , the change of MT levels in the copepod was correlated with metal concentration and duration .
