In the light of different equipments connected, BUS can be classified into internal BUS, on-board partial BUS, system BUS, and external BUS, among which the on-board partial BUS has the most significant influence to the performance of the system.

A comparative simulation of the behavior of three typical new thin strip cold rolling mills, HC-, CVC- and PC-typed mills,was accomplished for a comparision of their performance in sheet shape control. Theleffectiveness of these mills in controlling the roll gap and the contact pressure between the rolls are evaluated. Discussions on automatic sheet shape control system and key effective factors of tandem cold mills8 are covered along with an overview of the technological development tendency.

Because of DSR structure characteristics,the new mill has significant advantages over the conventional one in sheet shape quality,thickness accuracy,cost consumption,sum of investment,etc.

In sheet strips production, the requirement of glancing flatness for cold- rolled sheets i.e. automobile body sheet, tinned steel sheet, silicon steel sheet and aluminium sheet is higher .

The change of t_(8/5)and t_(8/3)are not obvious for the slab thickness of 6mm,8mm,10mm and 12mm,but when the slab thickness is 4mm,the t_(8/5)and t_(8/3) are the minimum and inner wall temperature is the maximum(635℃),and the thinner the slab thickness pipeline,the higher the inner wall temperature.

The results showed that the welding performances of WDB620 steel are good when its steel thickness is less than or equal to 36 mm and are close to the welding performances of NK-HITEN 610 U2 steel produced by NKK Company in Japan. The mechanics properties and welding performances of WDB 620 steel can completely meet the design requirements and can replace NK-HITEN 610 U2 steel.

The concept of the inverse sensitivity problem is used to design a method for autonomous (on-board) identification of the drift velocity of a gyrostabilizer when there is no possibility for laboratory experimentation.

Consideration was given to the combinatorial hierarchical design (composition) of the structure of an application telemetry system consisting of the on-board, radio, and ground communication equipment including the operator working place.

Various methods of vibration proofing on-board technical equipment and the results of the "Vibration" experiment on board the "Mir" manned orbital station are analyzed.

Long-term variability in water temperature and salinity in August has been determined for deep-water segments of standard profiles in the Central and Southern Caspian Sea based on data of on-board observations carried out in 1956-2000.

It is established that the samples recrystallized in a close volume under the on-board microgravity conditions "break off" from the container walls and touch the walls only in a few points.

Fracture is a common defect in sheet metal forming and it is essentially caused by tensile instability.

The CD results suggest an unfolding of PMC I and PMC II accompanying a decrease in the amount of extended (hydrated) coil structure and an increase in sheet-like structure.

In the engineering constructions the orthotropic continuous rectangular plates are often used. For instance, in a reinforced concrete building, the floor system consists of continuous rectangular plates supported by cross beams, and in ship building we often use the continuous rectangular glued plates.

In the engineering constructions the orthotropic continuous rectangular plates are often used. For instance, in a reinforced concrete building, the floor system consists of continuous rectangular plates supported by cross beams, and in ship building we often use the continuous rectangular glued plates. In analysing the stresses, theory which is derived for continuous isotropic rectangular plates is adopted. The results obtained is evidently different from the actual state, because the distribution of stress is much effected when the plate has different elastic properties in different directions, In this paper is presented a method of calculation, which takes into account the orthotropic properties of the materials. The results thus obtained will certainly much better approximate to the reality than when the classical theory is used. This paper contains the following items: 1. The bending of orthotropic continuous rectangular plates under loads normal to the plate. 2. The bending of orthotropic continuous rectangular plates under loads normal to the plate together with tensile forces acting in the plane of the plate. 3. The bending of orthotropic continuous rectangular plates under loads normal to the plate together with compressive forces acting in the plane of the plate. 4. The bending of orthotropic continuous rectangular plates. on elastic foundation. 5. The elastic stability of orthotropic continuous rectangular plates 6. The vibration of orthotropic continuous rectangular plates. For the first four items, we get a governing equation which connects the bending moments above three successive supports. For example, for the third case, we have: Several mumerical examples are included to illustrate the thoretical results obtained.

The load-supporting wall is the main construction element of the prefabricated building now in vogue. It is, in fact, a thin rectangular plate, along the boundary of which is reinforced a frame. The loads directly act on the frame. Our problem is to analyse the stresses both in the plate and in the frame. The method of solution this paper suggests consists in using the trigonometric series together with the principle of minimum strain energy.

The load-supporting wall is the main construction element of the prefabricated building now in vogue. It is, in fact, a thin rectangular plate, along the boundary of which is reinforced a frame. The loads directly act on the frame. Our problem is to analyse the stresses both in the plate and in the frame. The method of solution this paper suggests consists in using the trigonometric series together with the principle of minimum strain energy. On the basis of having satisfied the bi-harmonic equation for the plate, the requirement that along the connecting lines of the plate and the frame the displacements should be compatible is expressed by the condition that the strain energy of the whole system has to be minimum. Thus, we get a system of infinite simultaneous equations, from which to determine the necessary unknown coefficients. This article discusses two different loading conditions: the one concerns four concentrated loads at the middle of each sides of the frame, the other is for concentrated loads at each corner of the frame. From the rasults obtained, it can be known that the solution converges. very rapidly.
