In cell factor combination 6 stimulation,human bone marrow MNCs and AC133~+ selection cells were expanding much more than other cell factor combinations(P<0.05),and the clone density generated by cell factor combination 6 highered than the clone density generated by other combination stimulations under the same conditions(P<0.05).

Objective: To explore the potential ex vivo expansion ability of the human bone marrow mononuclear cells(MNCs) and AC133~+ selection cells under different cell factor combination stimulation.

Generally, the hatchability for practical use of the silkworm eggs after cold storage and acid treatment is not satisfactory, when the chilling period is less than 30 days, In order to increase the hatchability of silkworm eggs. Am experiment involving four factors: (A) duration of cold storage. (B) degree of high temperature exposed after the cold storage. (C) time exposed to high temperature and (D) duration of acid treatment was carried out to investigate their effect on the hatchability of silkworm eggs...

Generally, the hatchability for practical use of the silkworm eggs after cold storage and acid treatment is not satisfactory, when the chilling period is less than 30 days, In order to increase the hatchability of silkworm eggs. Am experiment involving four factors: (A) duration of cold storage. (B) degree of high temperature exposed after the cold storage. (C) time exposed to high temperature and (D) duration of acid treatment was carried out to investigate their effect on the hatchability of silkworm eggs in 4 perent strains: Zhejiang Agricultural University No. 1 (ZAU No. 1), Dong34 Sul2 and Dong Fei.Results obtained were as follows:1. After oviposition, the eggs of 4 races were kept in cold storage after having been under protection at 24℃ for 50-60 hours. For those races that were kept in cold storage for less than 30 days, (A), (B), and (D) had more effect than (C), There was interaction among 4 factors. These findings suggest that in practice selection for the integrated factor combination should be emphasized. 2. There were significant differences among races as to the range of the factors used so arrive at a satisfactory hatchability for practical use, There was broader range of these factors to be eelected for Dong 34 and Su 12. The range was narrower for ZAU No.1, and as for Dong Fei, no satisfactory factor combination had yet been found from the range of the 4 factors set for the present experiment.3. Results showed that for the current summer and autnmn races ZAU No.1, Dong 34 and Su 12, with the normal treatment, cold storage of 20 days would be sufficient to bring about a hatchability for parctical use of more than 90%. The effect of time of acid treatment on ZAU No. 1 was especially marked, and in case of short time cold stroage, appropriately prolong the duration of acid treatment would be worthy of consideration.

This paper studies the correlation between the growth in length and thickness of three puplar clones and the local climatic factor [combinations. Results of tests showed that the leading ecological factors giving rise to the variation of growth are ths annual average temperature, minimum temperature, accumulated temperature (≥10°C), cold index, annual precipitation and frost-free period. By means of successive regression, the optimum equations worked out for growth of the clones are as followes:...

Explained in this paper is guided by the study of the rule of gold minealization and prerequiste of prospecting. In this work, we used the remote sensing combined with the geophysical and geochemical data to extract the, useful information of mineral-formation concerned, and by means of the establishment of synthetic elements of interpretation, the three dimensional synthetic interpretation, the analysis of mineral-formationg geological condition. the mathematic statistical and quantitative calculation of controlling factors as well as the determination of the best factor combination of mineralformation and image elements to delineate the minerogenetic prospecting area and point out the possible spatial location ,of industrial deposit. Finally, by way of the field synthetic verification, we attained the aim of prospecting of gold deposit. We also studied and probed into the theory and methods of remote sensing technology for the exploration of gold deposit and have obtained a good results.
