To explore correlation between the tk gene structure of pseudorabies virus (PRV) and its virulence, to study the effect of the gene mutation on PRV biological properties, and to investigate mechinism of reduced virulence, thymidine kinase (TK)-deficient mutant of pseudorabies virus strain Hubei (PRV HB) was isolated by selection for resistance to 5-bromodeoxyuridine. The tk genes of PRV HB and its TK mutant were cloned and sequenced. 1587 base pairs of the tk gene and flanking regions of wild-type (wt) virus were sequenced, which included an open reading frame (ORF) of 1098 bp encoding a protein of 366 amino acids. The ORF contained two 137-bp repeated sequences, which were connected by an adenosine. 1458 bp of the tk and flanking regions of TK- mutant were sequenced. Analysis of the tk gene sequence of TK mutant indicated that one of 137 bp repeated sequence and the connecting adenosine in the tk gene of the wt virus was deleted and a repeated sequence of 8 nucleotides (GCGCGCC) was inserted.

This paper analyzes the pipe network system of oil-gas collection and transportation for offshore oilfield development. A '0-1' integer linear programming model is constructed to optimize the investment of seabed pipe network. The mathematical model is solved by the spanning tree method of graph theory and network analysis. All spanning trees of a network graph compose all the feasible solutions of the mathematical model. The optimal solution of the model is the spanning tree with the minimum cost among all spanning trees. This method can be used to optimize the seabed pipe network system and give a minimum cost plan for the development of offshore marginal oilfield groups.

THE Yellow River, with its huge amount of silt charge from the Loess Plateau, is the secondlargest river in China. Its lower reach has become a famous hanging river because of serioussilting up, and the magnitude of discharge changes much from season to season. As a result ofsilting, migration of the stream channel happens frequently. Lateral erosion of channel or pointbars, and scarp slopes forming during the erosion may be often observed. The silt stalactite,hitherto not reported, usually forms on surfaces of the slope. As a newly found kind of sedirnen-tary structure, the silt stalactite may have some significance to the study of sedimentary envi-ronments and paleoclimate.
