(An optical fibre evanescent field sensor for methanol
(CH3OH) and ethanol (C2H5OH) solvents based on deformed optical
fibre cores is reported. The sensitivity of an existing U-bend
probe is increased by extending the exposed core to a coil shape
of one and a half turns and by forming the core to a meander
shape with three bends. Using the visible wavelength area (VIS)
and methanol/ethanol concentrations from 0 to 10 it is shown
that the sensitivity of the meander shape sensor enables the determination
of methanol concentrations of better than 0:5 and of
ethanol concentrations of better than 0:2 at 650nm. This facilitates
the use of low cost optical sources and receivers provided for
this wavelength range as well as the utilization of polymer optical
fibres to guide the light to and from the sensor which results in low
cost applications compared to all silica or polymer clad silica fibre
solutions in the near-infrared (NIR) or ultra-violet (UV) wavelength
range.)

说明: 编写带缓存的文件操作类
从执行体程序库中的CLLogger类可知,通过缓存要写入文件中的数据,能够提高读写磁盘的性能
请编写一个文件操作的封装类,其要求如下:
需要提供open/read/write/lseek/close等函数的封装函数
该类要提供数据缓存服务。
调用该类的写操作接口时,数据要首先写到缓存,然后再根据策略写到文件中。
调用该类的读操作接口时,该类能根据策略缓存读出的数据
读写缓存要保持一致性
(From the implementation of the CLLogger class library, we can know, through the cache to write data in the file, you can improve the performance of the read and write disk
Please write a package for the operation of the class, and its requirements are as follows:
The encapsulation function of open/read/write/lseek/close and other functions is required.
The class to provide data cache services.
When the write operation interface of the class is called, the data must first be written to the cache, and then the policy is written to the file.
When a read operation interface of the class is called, the class can read the data according to the policy cache.
Read/write cache to maintain consistency)
