文件控制块 (fcb) 是用来存放控制文件需要的各种信息的数据结构，以实现“按名存取”。fcb主要包含以下信息:①基本信息，如文件名、文件的物理位置、文件的逻辑结构、文件的物理结构等。

A File Control Block (FCB) is a file system structure in which the state of an open file is maintained. A FCB is managed by the operating system, but it resides in the memory of the program that uses the file, not in operating system memory.

1998年9月1日 · This paper introduces a technology named FCB (Fast Cut Back), in which the power plant disconnected from the power network is put into a state of idling operation right after the action of the circuit breaker, and resumes power supply when the power system has recovered normal operating conditions.

2020年11月17日 · FCB (file control block)文件控制块 对于操作系统而言，当任何一个文件存储在本地后，会为了方便后续读取管理，而为每个文件建立专门的用以收集必要属性信息的数据结构，称为FCB（概念借鉴自进程管理模块中的PCB process control block )。

2019年7月8日 · Ge et al. developed the FCB method to directly estimate the single-differenced satellite FCB in the forms of WL and NL by averaging the fractional parts of the corresponding float ambiguities. The float ambiguities recover its integer nature using the WL and NL FCB products; the positioning accuracy improved 30% in the east component, compared ...

All the components as well as the device case are connected through a flex circuit board (FCB), as shown in Fig. 2. The ICs are mounted on the back of the FCB, which is folded in half before...

2018年11月13日 · 国内外学者为实现固定解PPP，提出了小数周偏差 (fractional cycle bias, FCB)法、整数钟法、去耦钟差法等方法 [4-6]，且已有研究证明了上述方法的等价性 [7-8]。 其中，FCB方法提出最早且应用较广：文献 [9]最早估计了星间单差的FCB，但限于当时星历的精度，仅能有效分离出宽巷模糊度的小数部分；文献 [4]采用IGS (International GNSS Service)参考网数据，成功获得宽巷和窄巷的FCB，实现了单差的固定解PPP；文献 [10]引入模糊度基准后生成非 …

2019年10月17日 · 汽轮发电机组FCB（Fast Cut Back）的功能作用是当机组运行中突发对电网的输出电功率中断，FCB可实现发变组解列后汽轮机和锅炉维持运行，发电机独立带厂用电系统稳定运行。 待外部故障消除，电功率输出条件恢复后，机组迅速重新并网。 如送出方式采用双母线接线的发变组，当所连接母线故障解列后依靠FCB功能实现“孤岛”运行，将输出回路倒排至另一母线即可重新并网，在此过程中汽轮机和锅炉避免了一次启停。 机组的FCB功能对提高电网的稳 …

Microfluidic systems enable automated and highly parallelized cell culture with low volumes and defined liquid dosing. To achieve this, systems typically integrate all functions into a single,...

When a blackout event takes place in the power grid, Fast Cut Back (FCB) thermal power units can provide black start service and recover the power system.
