KCR and HCD are erucic acid synthesis genes. In order to reveal the relationship between the synthesis of erusic acid and the quantitative expression of its functional genes, and to reveal the theoretic base of the breeding for high erucic acid content, the expression of KCR and HCD had been analyzed kinetically and quantitatively by using regular reverse transcription polymerase chain reaction and the internal standards of QuantumRNA18S during the growing period of high erucic acid content lines of Brassica Juncea.

In this thesis, the methods of surrounding rock masses stability classification on the basis of the geological documentation of muck and the boring parameters of TBM are approached, especially as follows:①The geological documentation of muck and the boring parameters of TBM in the Yellow River Diversion Project.of shanxi province is summarized systematically;②Based on the geological documentation of muck and the boring parameters of TBM, that whether the common methods of surrounding rock masses stability (the methods of regular factor classification) classification are feasible, is carried on the discussion;③According to the corresponding relation of muck and the boring parameters of TBM and the surrounding rock masses stability type, the extension assessment method of tunnel surrounding rock masses stability classification is set up, also the corresponding fortran calculation procedure worked out, and not only rational result in conformity with the reality can be obtained, but also the stability situation of surrounding rock masses in front of the working range can be predicted according to the change of the dependent value in the application instance of Yellow River Diversion Project;④Combining with the application instance of Yellow River Diversion Project, extension assessment method in the application of surrounding rock masses stability classification is compared and verificated in detail by applying fuzzy synthesis method by forefathers, and a certain degree discussion and summary about the application achievement of surrounding rock masses stability classification, which is assessed by extension assessment method and fuzzy synthesis method, are carried on.
