The invention relates to a large-sized combined dynamic and static multifunctional geotechnical engineering simulation testing device which comprises a plurality of counterforce stand devices, a front visible counterforce beam, a rear loading counterforce beam, an arch-shaped dynamic counterforce frame, a hydraulic loading system, a servo dynamic loading system, a model elevating translational trolley system and the like, wherein each counterforce stand device is formed by connecting a top beam, a side beam and a bottom beam through flanges and high-intensity bolts and can be combined freely according to a testing model; the left and the right parts of the front and the rear counterforce beams are connected with the side beam; the upper and the lower parts of the front and the rear counterforce beams are connected with the model elevating translational trolley system through pull rods; the hydraulic loading system is arranged in a steel grid formed by the top beam, the side beam and the rear loading counterforce beam; the arch-shaped dynamic counterforce frame is independent; and after the top beam is detached, the servo dynamic loading system can be arranged. The testing device is compact and reasonable in structure, narrow on the upper part and wide on the lower part, assembled flexibly, easy to operate, and convenient to load and observe and can be applied to planar and three-dimensional geomechanics static and dynamic model testing of geotechnical engineering under the conditions of foundation pits, side slopes and high ground stress.

A tree-structured dynamic encoder generates an N-bit encoder output word in response to each encoder input word of a sequence of encoder input words, such that the number of encoder output word bits of value 1 equals a value of the encoder input word and such that positions bits of value 1 within the N-bit encoder output word for each give value of encoder word varies with time. Some or all of the switching blocks produce more than two block output words in response to each block input word. The dynamic encoder includes a tree of switching blocks, each dynamically encoding a block input word into more than one block output words, each having fewer bits than the block input word. A sum of values of the output words of each switching block always equals a value of that block's input word. A switching block of the highest layer of the tree receives each successive encoder input word as its block input word, and each switching block of each layer of the tree other than a lowest layer supplies each of its at least two block output words as a block input word to a separate switching block of a next lower layer of the tree. Each switching block of the lowest layer of the tree generates single-bit block output words, each forming a separate bit of the N-bit encoder output word.

The invention discloses a making method of a frequency domain transmission function shape dynamic tuning spectral filter, the making process of the making method is that an ITO electrode (5), a plurality of polymer micro-rings (P1, P2...Pn) with different radii, polymer claddings (4) and electrode round rings (E1, E2...En) are orderly arranged on the axial grinding plane (1) of a D-shaped fiber which is grinded; the polymer micro-rings with different radii are perpendicularly coupled with fiber cores (2); different bias voltages are applied on each of the polymer micro-rings (P1, P2...Pn) to change the resonance frequency of each of the polymer micro-rings (P1, P2...Pn), and the frequency domain transmission function shape of the filter is dynamically changed through adjusting the bias voltage (V1, V2...Vn) of the polymer micro-rings (P1, P2...Pn). The making method is suitable for making various dynamic flat-channel and power-equalization devices.

The invention relates to a cold rolling strip steel plate shape dynamic variable gain control method. Plate shape dynamic variable gain coefficient and speed gain coefficient are related to plate shape deviation coefficient and elasticity modulus deviation coefficient. Rolling force fluctuation influence is considered in elasticity modulus deviation coefficient calculation. Field actual application calculation method and data of each coefficient is given in plate shape dynamic variable gain coefficient calculation. The method has the advantages that introduction of a dynamic variable gain controller, system dynamic quality problems caused by pure lag during plate shape control are solved effectively, robustness of a plate shape control system is improved while good dynamic features and robustness of the dynamic variable gain control is also considered, and steady-state errors are eliminated to allow the control system to form a floating system.

The invention discloses a dynamic bionic sub-soiling device with a soil crusher. The dynamic bionic sub-soiling device is composed of a transverse beam, a shovel handle, a shovel wing and a chain-shaped dynamic bionic soil crusher, wherein the shovel handle is fixed on the transverse beam and the shovel wing is fixed under the shovel handle; the rear side of the shovel handle is connected with the chain-shaped dynamic bionic soil crusher; the chain-shaped dynamic bionic soil crusher is composed of soil crushing heads and a connection circular ring; the soil crushing heads are connected together through the connection circular ring; tapered bulges are arranged on the surfaces of the soil crushing heads; and the tapered bulges are arranged toward the inclined front side. In a sub-soiling process, a sub-soiling shovel is used for breaking a plough pan, but cannot completely crush the plough pan; then the chain-shaped dynamic bionic soil crusher following the sub-soiling shovel is used for crushing the soil through the sharp tapered bulges on the surface of the chain-shaped dynamic bionic soil crusher, so that the disadvantage that a traditional sub-soiling shovel cannot sufficiently crush the soil can be overcome, and the effect of sub-soiling work is given a full play.

The invention discloses a cement combined grinding system. Raw materials enter a pre-grinding vertical mil by virtue of a feeding lifter, so that fine powder, medium-coarse powder and coarse powder are obtained; the fine powder, the medium-coarse powder and the coarse powder enter a dynamic and static combined type three-separation powder concentrator from an inlet of a V-shaped powder concentrator for being output in three parts; the fine powder enters a cyclone cluster from a fine powder opening of a cage-shaped dynamic powder concentrator and is warehoused by virtue of a warehousing lifter; the medium-coarse powder enters a ball mill from a medium-coarse powder opening of the V-shaped static powder concentrator, so that fine powder is obtained, and then, the fine powder is warehoused by virtue of the warehousing lifter; and the coarse powder is recycled into the pre-grinding vertical mill from a coarse powder opening of the V-shaped static powder concentrator for being re-grinded. According to the invention, by virtue of the system which consists of the pre-grinding vertical mill, the ball mill and the dynamic and static combined type three-separation powder concentrator, adaption to different materials and different system states is improved by virtue of a series of regulations, so that the optical balance point is found, the graduation efficiency is improved, and the energy consumption is reduced, and therefore, product particle shapes and a product particle formula are improved.
