The grain oriented silicon strip was rolled by cross shear rolling (CSR) and then annealed to manufacture non-oriented thin silicon strip of high quality. The recrystallization of rolled grain-oriented silicon steel into non-oriented silicon steel was studied. For this purpose, CSR is better than conventional rolling, and the higher the mismatched speed rate is, the better the properties of the non-oriented thin silicon strip are. The optimum annealing schedule is heating at 1 000 ℃ for 1 h in pure hydrogen atmosphere added with H 2S of 0.001 0 %.

Cyclic variability is a factor adversely affecting engine performance. In this paper a cyclic moving average regulation approach to cylinder pressure at top dead center （TDC） is proposed, where the ignition time is adopted as the control input. The dynamics from ignition time to the moving average index is described by ARMA model. With this model, a one-step ahead prediction-based minimum variance controller （MVC） is developed for regulation. The performance of the proposed controller is illustrated by experiments with a commercial car engine and experimental results show that the controller has a reliable effect on index regulation when the engine works under different fuel injection strategies, load changing and throttle opening disturbance.

In specific condition, when wrapping angle of cold rolling strip covering surface of shape detecting roll dynamically changes, online radial compression of the shape detecting roll is changed too, and it seriously affects online shape detecting precision of cold strip. Based on the latest intelligent shape meter developed by Yanshan University, using PSO-BP neural network and actual working condition datum, the cold strip online dynamic wrapping angle compensation model is established, and successfully applied in 1250 mm 6-high cold mill, remarkable results are achieved. The error between calculated values and measured values of total tensions is within 3 %

A roll shape setting model was built for the hot galvanizing and planishing mill. The uniform transversal distributions of the front tension in the exit and the unit pressure were considered as the objective function. At the same time, the quality of the products, the stability of zinc layer, and the homogeneity of spangles were of considerable significance in the planishing process. The model was applied to the roll shape setting of the 1800 cold rolling 3# CGL hot galvanizing and planishing mill of Baosteel Co Ltd. After being planished, the flatness of a strip that was less than 6 I was more than 97%, and the flatness of others were less than 10 I; the pass percentage of the zinc lay- ers reached 100%.

We study the mean-square composite-rotating consensus problem of second-order multi-agent systems with communication noises, where all agents rotate around a common center and the center of rotation spins around a fixed point simultaneously. Firstly, a time-varying consensus gain is introduced to attenuate to the effect of communication noises. Secondly, sufficient conditions are obtained for achieving the mean-square composite-rotating consensus. Finally, simulations are provided to demonstrate the effectiveness of the proposed algorithm.

Regulatory T （Treg） cells play a critical role in the maintenance of tolerance. B-la cells belong to a specific and functionally important B-cell subset that exerts its regulatory role through the production of IL-IO. While IL-IO has been correlated with the induction of type 1 Treg （Trl） cells or Trl-like cells, whether IL-lO-producing B-la cells are able to induce Treg cells, especially the Trl lineage, is poorly understood. We have demonstrated that, similar to the reported B-2 cells, B-la cells are able to convert naive CD4＋CD25- T cells into a subset of T cells with suppressive function, which we called ＇Treg-of-Bla＇ cells. Treg-of-Bla cells do not express Foxp3, but upregulate the Treg markers OX40, programmed death 1 （PD-1）, inducible costimulator （ICOS） and IL-IOR. Moreover, Treg-of-Bla cells do not express Foxp3 and produce high levels of IFN-y and IL-IO, but minimal amounts of IL-4; therefore, they resemble Trl cells. However, utilizing IL-10-/- mice, we showed that IL-IO was not involved in the induction of Treg-of-Bla cells. On the contrary, CD86-mediated costimulation was essential for B-la cells to drive the induction of Treg-of-Bla cells. Finally, we demonstrated that, in contrast to the Treg cells generated by B-2 cells that mediate contact-dependent suppression, Treg-of-B la cells suppress through secreting soluble factors. While Trl cells mediate suppression mainly through IL-IO or TGF-10secretion, Treg-of-Bla cells mediate suppression through an IL-10- and TGF-10-independent pathway. Together, these findings suggest that B-la cells induce a functionally and phenotypically distinct Treg population that is dissimilar to the reported Foxp3＋ Treg or Trl cells.

Quantitative level evaluation of cold-rolled strip was significant for the shape control and the product structure optimization. Based on the probability statistics method and the shape pattern recognition method, the shape evaluation model of cold-rolled strip was established to evaluate real-time shape of the online strip. The model was embedded in the shape control system, and the online strip shape state was real-time observed whether to meet the technical indicators, so the shape level could be identified and evaluated. Based on the shape evaluation indicators, the shape component could be well controlled to improve the shape hit rate and the control stability, so that the rolled strip shape could meet the technical requirements. At a 1050 cold strip mill, the shape data of the scene typical specifications strip were online collected and real-time evaluated, and the hit of macro shape in less than 8 I was 68.44%, indicating that the mill shape control had considerable room for improvement, as well as the evaluation method was feasible and practical for quantitative evaluation of the strip shape. So the new evaluation model has important guiding significance to increase value-added and reduce product quality objection.
