And its library is a social and national public industry, is an important to improve quality, to eliminate knowledge poverty of public welfare undertakings, for all the members of the society it equal, free service, is a kind of public welfare services forever, can't also cannot be "independent" to the survival and development, just as the us master of library science zerah said "public service is the basic aim of the library". 1.2 Digital Library Information Resources Environment Traditional library information resources mainly in books, journals, newspapers and other paper written materials as the main source of information, in the digital environment, the library can be obtained through the network electronic books, electronic journals, electronic BBS, multimedia and so on a variety of information sources, the addition of it makes the library collection ranging from paper documents, electronic documents, both "real collection", also including "virtual library", greatly expand and

These materials offer suitable properties for various applications; however its low resistance in moist environment is their significant weakness.
Another commonly used material for mortar modification was the blood [10], or other bio-based materials [11].
