滴瓶

Dissolve 0.5491 g of KH2PO4 in a 250 ml volumetric flask with water. Store in a dark cupboard no longer than 6 months. Preserve with three drops of toluene.

在250ml 容量瓶中用蒸馏水溶解0.5491g KH2PO4，可以加3滴甲苯避光保存于试验柜中，不超过6个月

In this study,the strain CH-la isol ated from china was used as vaccine virus,the rolling bottle technique was adopted to propagate higher titer PRRS virus on Mare-145 cell lines.

本研究选用国内分离的猪繁殖与呼吸综合征病毒CH-1a株作为疫苗用毒株。利用转瓶细胞培养技术，在Marc-145细胞上大量增殖了较高滴度的猪繁殖与呼吸综合征病毒。

MERCURY SOLUTION FOR STANDARDIZING DITHIZONE TITRANT : Transfer 2.0 mL of Mercury Stock Solution to a 100-mL volumetric flask, and dilute with 1 N sulfuric acid to volume.

规范化的双硫腙滴定试药MERCURY解答：调动2.0 mL水星 Stock解答到100ml容量瓶，和用1 N硫酸稀释对容量。

The dosage is determined by pH control approach, which does not require a routine jar test. This method can simultaneously determine the optimal pH and economical dosage for oxide-CMP wastewater. The coagulant can be added directly into the raw water without the pH adjusting at first. According to this method, the coagulant acts like a titrant and the pH of the oxide-CMP wastewater is monitored. The optimal dosage is the one that corresponds to a specific pH.

本论文主要以「pH控制法」来决定线上加药剂量值，其与传统瓶杯试验不同的是，其加药逻辑可直接对线上加药进行控制且毋须定期确认参数。pH控制法视混凝剂为酸滴定药剂，直接对进流之氧化层研磨废水进行加药，及至特定pH时，加药停止，此时之加药量即为电性中和去稳之控制点，远较过量加药法经济。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
