| 1. | The result is a dramatically sharp chromatographic peak , even with samples with a high ph
由此显现完美之层析波峰，甚至样品具高酸硷值亦然。 |
| 2. | Acid rain has lowered the ph of high - elevation streams , pushing trout out of their habitat
酸雨把高海拔溪流的酸硷值降低了，鳟鱼被迫远离家园。 |
| 3. | Inability to adapt to changes in ph levels and salinity and temperature changes when introduced into the pond
适应虾池酸硷值盐度及温度大幅度的变化。 |
| 4. | Mightysil gp is a versatile , highly reliable hplc column designed for use with a variety of samples having a wide ph range from acidic to basic
Mightysil gp为一用途广泛，且具高信赖度之管柱，可用于分析多种具备广泛酸硷值之样品。 |
| 5. | 3 the operators should monitor the ph value of the fish tank water preferably on daily basis to ensure that the ph is within the range of 7 . 2 to 7 . 8 for optimal disinfection
3经营者宜每天监测鱼缸水的酸硷值，确保酸硷值介乎7 . 2 |
| 6. | The problem often faced by shrimp farmers is isolating factors which cause stress to the shrimp . these factors include water quality and pollution of the pond bottom
尽量使苗场的酸硷值ph盐度与放养虾场的池水一样，放养宜在清晨或黄昏。 |
| 7. | Natural mild acidic foaming agent that is similar to the skin ' s ph level ; able to create rich leather cleansing foams and makes the skin feeling fresh without drying
天然的弱酸性起泡剂，与皮肤之酸硷值贴近，可产生丰富细致的泡沫，洗后肌肤健康清爽，没有绷紧作用。 |
| 8. | A water sample of the swimming pool should be taken at least once a month for testing during opening hours to ensure that the chlorine level and the ph of the water met the above standard
于泳池开放时间内抽取池水样本化验，最少每个月一次，以确保池水的氯含量及酸硷值符合上述标准。 |
| 9. | Those key parameters that the epd monitors and uses for calculating the wqo compliance rate include ph , dissolved oxygen , 5 - day biochemical oxygen demand , chemical oxygen demand and suspended solids
环保署用于监测和评估水质指标达标率的主要参数包括酸硷值溶解氧五天生化需氧量化学需氧量及悬浮固体。 |
