However, because the fine-grained sediments was easy to move in the naked tidal flat, the tidal creek had periodic north-south moving at the intertidal zone and the moving period was about 9 years.
Because a large number of sediment was supplied from the ancient Yellow River and the abandoned Yellow River Delta, the coastline of the study area moved seawards about 70km from 1128 to 2012.

The reason is that the undeformed chip average thickness of single grain decreases with wheel speed increasing while the number of effective abrasive increasing, as well as the plastic deformation depth decreases accordingly.

The DMW is damaged on the boundary of the diffusion layer, wherein the base matrix has lower chromium content and undesirable carbides on grain boundary are examined. 5) The degradation process of DMW damage is repeated due to cyclic startup of Units. 6) Operation condition, mainly temperature, leads to the formation of secondary carbides due to diffusion process because the first deposit is not stabilized steel.

The outcomes include shortening the reaction time and improving the reaction efficiency, enhancing the formation rate, refining grains, influencing phase change process and so on.
It demonstrates that with the impact of magnetic field a large number of dislocations having diverse morphology are produced in the sample.

Due to the high strength and wear resistance of the D6AC steel [4, 5] a number of the mining equipment manufacturers use the steel under consideration as a material for producing drill bits, casings, bearings instead of the conventional case-hardening steels [6, 7].

The integration of Co-W-Zr into the Ni(P) matrix notably enhances the number of active sites during the hydrogen evolution reaction.
Common fabrication methods include vacuum melting and powder metallurgy, though challenges like segregation and grain coarsening persist.
The diffraction peaks around 2θ = 45.12° and 82.69° match those of FCC Ni according to JCPDS card number 1534892, confirming phase purity.

Numerical simulations were performed under rational assumptions regarding the mechanical behavior of ICV parts, limited to a number of minimal elements that secure a smooth work of the device and a fast response to upwind and downwind liquid pressure variations.
A small but secured delay between the opening of the start valve and the combustion of the solid grain had to be provided.

Area index refers to the numbers of FPGA logic resources taken up by the design, which is commonly measured by the logical unit number taken up by each pattern (LEs/char), equaling to the logical unit number of the entire system divided by the sum of the length of all patterns, in which each logical unit includes a lookup table (LUT), a flip-flop (FF) and related associated logic.
They pointed out the number of basic unit circuit required by N-status of NFA directly achieved in the integrated circuit is no more than O (N).
Since the number of States and the transfer edge take up a large amount of logic and wiring resources, so far the DFA implementations are usually based on FPGA-based Block RAM and SRAM[12].
The rational use of the default transfer can greatly reduce the number of transfer edges required for each state.
In order to evaluate the experimental results in a more fine-grained perspective, the 102 rules have been classified into two categories: simple (including 62 rules) and complex set of rules (including 40 rules).
