The distribution system design is critical to the overall performance of the WFI system.
分配系统的设计对注射用水系统的总体性能是关键的。
Distillation is the most common method for production of WFI from feed water that generally meets USP PW specifications.
蒸馏是最普遍的从符合USP纯化水标准的源水制备wfi的方法。
For WFI systems, the FDA Guide recommends sampling daily from a minimum of one point of use, with all points of use tested weekly.
对于注射用水系统，FDA指南建议至少每天要从一个用点取样，在一周之内将所有的用点都取到。
The mean Oswestry Disability Index questionnaire score of steroid-group's patients was statistically significant lower than that of the WFI-group at all postinjection re-evaluations.
激素组中的患者Oswestry功能残障指数评分在注射后所有的再评估中均明显低于注射用水组。
Key utility system in pharmaceutical industry plant are HVAC system and water system, and water system include city water system, purified water system and WFI (water for injection) system.
制药工厂生产相关的主要公用系统有空调系统及水系统等，水系统包括一次水(饮用水)、纯水及注射用水。
When cold WFI is needed, the cooling mode (fig. 5) is turned on by an air switch, which closes the recirculation valve and opens the cooling water valve. Within seconds cold WFI is available.
当需要冷却注射水时，系统通过一个空气开关打开冷却模式（图5 ），同时关闭了循环水阀门打开了冷却水阀门，只需几秒钟，就可以得到冷却注射水了。
