This paper is concerned with chaotification of discrete Lagrange systems in one dimension, via feedback control techniques. A chaotification theorem for discrete Lagrange systems is established. The controlled systems are proved to be chaotic in the sense of Devaney. In particular, the systems corresponding to the original systems and designed controllers are only required to satisfy, some mild assumptions.

Germination of soybean seed is always arrested by chilling imbibitional stress, and this phenomenon is widespread in the plant seed kingdom, but has not been studied at molecular level. In this experiment, cDNA-amplified fragment length polymorphism （cDNA-AFLP） technique was applied to isolate genes relevant to chilling stress （4℃） during soybean seed imbibition. Eight genes were found to be up-regulated and two were down-regulated during chilling stress respectively. Four up-regulated genes were selected to analyze the expression profiles during imbibition under chilling condition. It was demonstrated that the four genes were induced significantly by 4℃ for 24 h, and decreased when the temperature was shifted from 4 to 22℃. GMCHl, a highly chilling stress-induced gene which responded to abscisic acid （ABA）, polyethylene glycol （PEG） and NaCl, showed great stress-resistance according to published reports. Cos78 was identified to be induced by PEG. However, Cos66 and Cos36 transcription showed no change to ABA, PEG, and NaCl. From the characteristic of genes isolated from the embryonic axis, we concluded that soybean seeds have different pathways to adapt to various biotic and abiotic stresses by regulating many signal transduction pathways.

The process model for BOF process can be applied to predict the liquid steel composition and bath temperature during the whole steelmaking process. On the basis of the traditional three-stage decarburization theory, the concept of mixing degree was put forward, which was used to indicate the effect of oxygen jet on decarburization. Furthermore, a more practical process model for BOF steelmaking was developed by analyzing the effect of silicon, manganese, oxygen injection rate, oxygen lance height, and bath temperature on decarburization. Process verification and end-point verification for the process model have been carried out, and the verification results show that the predic- tion accuracy of carbon content reaches 82.6% （the range of carbon content at the end-point is less than 0. 1wt%） and 85.7% （the range of carbon content at end-point is 0. 1wt% -0.7wt%） when the absolute error is less than 0.02wt% and 0.05wt%, respectively.
