您要查找的是不是:
- microhorizontal buret 微量水平滴定管
- Use parafilm to secure the tip of the buret. 要用石腊膜保护滴定管的塑胶头。
- A buret is used to titrate liquids. 滴定管用于液体滴定。
- Whenever he gave her a bear hug , she buret into tears. 每当他抱她时;她总是激动得流泪.
- After rinsing out the buret, fill it with the NaOH solution. 在滴定管淋洗完毕后,用NaOH溶液注满。
- The buret is filled with a specified volume of a liquid. 首先在滴定管中加入一定体积的液体。
- A slowly drained buret will also provide greater reproducibility of results. 慢慢让液体排出也可以使结果的重现性更好。
- Tilt the buret to allow the entire inner surface of the buret come into contact with the liquid. 使滴定管倾斜,让滴定管的整个内表面都能与溶液相接触。
- The tendency of liquids to stick to the walls of the buret can be diminished by draining the buret gradually. 让滴定管中的液体慢慢流出可以减少液体黏在管壁的情况。
- Warning: Be sure no drops are left on the tip of the buret when you are reading the pH. 警告:必须确保在读取pH值的读数时没有液滴留在滴定管的壁上。
- The plastic tip helps in the formation of small droplets of solution to drop from the buret. 塑胶头会帮助滴定管滴出细小液滴。
- Estimate what you think the uncertainty is in weighing, using the buret, and in endpoint location. 估计一下在秤量,使用滴定管和确定终定位置的不确定度。
- Make all buret readings by estimating the nearest 0.01 mL, allowing time for drainage. 所有滴定管的读数要估读至0.;01mL。让滴定管中液体流一段时间。
- Measuring tools: measuring cylinder, measuring cup, measuring bottle, buret, straw etc. 烧器类:如烧瓶、烧杯、三角烧瓶各种规格。
- Each time you fill the buret with fresh solution, rinse the buret 3 times with 2 mL of the new solution, discard each wash. 在你每一次用新鲜的溶液装满滴定管时,要用2mL的新鲜溶液淋洗滴定管三次。弃去每一次的淋洗液。
- The parallel determination results were compared with those obtained from the conventional buret by mathematical statistics methods. 通过数理统计的方法,将微型碱式滴定管与常规碱式滴定管平行测定结果进行了比较。
- High-quality buret have a venting-mechanism with which they can be very easily refilled with the exact volume for which the buret is calibrated. 高级的滴定管都有一种抽液功能使它们每次在滴定完毕时可以很精确地将滴定液加到精确的刻度。
- The glass instruments which we produced, classified to the qualities and capabilities as follow:Measuring tools: measuring cylinder, measuring cup, measuring bottle, buret, straw etc. 本厂生产的玻璃仪器,根据性能和要求可分为:量器类:如量筒、量杯、量瓶、滴定管、吸管各种规格等。
