Based on the Kylin SFS, this paper advances the technology of encrypted filesystem space, which classifies the encrypt safe to give a flexible encrypted storage support to the different service program ; at the.

Analysis of 122 occupational accident cases in confined space;

This paper chosed special representative confined spaces as study objects, summarized the total character of indoor air pollutants and its influence factors, provided reference for controlling and management of pollutants.

A study is made of the effect of different acidizing conditions such as concentration,temperature and time on humidity-controlling properties of sepiolites in closed space at constant temperature.

Author points out that the outer and semi-outer public space should not be increased in design on the contra outer and semi-outer private space should be adopted.

The simulation results indicate that the cryptosystem can enlarge the key space and resist the brute attack.

Compared with other generators,it has several merits such as the unpredictability of the sequence,bigger secret key space,smaller storage space,simpler algorithm and easier to implement in addition to its long period,.

The algorithm encrypts data by one-time one-key and multiple encryption, its key space is big enough and can defend effectively ciphertext-only attack of network s illicit users.
