Fretting wear usually causes the reduction of tube thickness, which might cause the contamination of the coolant by radioactivity [3].
After the tests, the change in the wear scar of the tube was recorded by using surface profile meter and these data was used for estimating approximate wear volume.
The wear depth was decreased due to the reduction the amount of the amount of the relative slip between tube and grid.

The reduction of pure iron freezing point by element is in direct proportion with the concentration of the element.
In experiment, the migration of Si can also decrease the melting point of pure iron, and the melting of pure iron plays a vital role in the reduction of molten steel, so it’s important to study the influence of boron on iron base melting.
And the content of boron is 1.34%, which is close to the data of Fig. 1.

By thermodynamic data of the reaction (△G is the Gibbs free energy, T is the alloy temperature)，we can see: When the alloy temperature is 720˚C, that is 993K, The change of reaction standard free enthalpy is less than zero that indicates reduction reaction can be automatically The results show that at the standard state, Nd could deoxidize Al from Al2O3 and Al2O3 inclusions are significantly reduced.
The product Nd2O3 of reduction reaction in aluminum liquid might be deposited and enriched in the bottom of crucible.

Introduction As the automotive industry has kept seeking the lighter car body, Al alloys became the most practical solution for weight reduction of automotive components[1,2].
Even though development of new Al alloys with higher formability would be the most desirable goal to expand Al alloy application for lighter weight car, the new forming process to best use of Al formability now available would be another way to increase Al usage for weight reduction.
At the temperature of 500oC, elongation got higher with the increment of strain rate, which was contrary to those data at lower temperatures as well as a usual knowledge.

Under acidic conditions, the oxidation-reduction potential of the ferrate(VI) ions (2.2 V) is greater than that of ozone (2.0 V).
Under acidic conditions, the oxidation-reduction potential of FeO42- is 2.2 V, which is a very strong oxidant.
Our experimental data demonstrated that either ferrate(VI) alone or ferrate(VI) with H2O2 processes are promising techniques for the decolorization of Mordant red 15 dye in water.

And, at strict statement of a question, not only reduction, but also increase in discharge passed through fish pass are not comprehensible.
Hence, even slightly regulation of discharge of station can lead to uncontrolled reduction of fish pass discharge on 50 % and more.
According to ichthyologic research, or reference data, the minimum values of water depth and width of fish pass, necessary for pass of the largest species of passing fish, as well as admissible speeds of water in the fish pass are defined. 2.

The Sea Voyage Data Recorder (VDR), can automatically record the ship status and operating information and access to navigational data equipment, will plays a key role in investigating the accident, identifying the cause and fixing the responsibility.
The electronic data is a new kind of evidence, which is the result of science and technology development.
For the concept of electronic data is currently no uniform identification, I believe that we can draw on the concept of "data message" in "Electronic Signature Law": "data message refers to the information generated, sent, received or stored by electronic, optical, magnetic or similar means. " Although this provision is applicable in the field of e-commerce law, electronic data also exists in navigation, so the electronic data also apply in the maritime evidence.
In addition to the traditional forms of documentary evidence, physical evidence, witness testimony, etc., ship navigation data described by VDR and ECDIS is static electronic data, and dynamic evidence can be obtained assisted by simulation capabilities of simulator that a more realistic cases reduction process can be achieved, the provisions of "Civil Procedure Law" provides legal support for this kind of maritime evidence.
This incident process reproduce is based on real data, which is of more convincing, and objectivity and fairness, it is more persuasive than the expert opinion.

This reduction in peak intensity suggests a decrease in the crystal density in the film.
This may be attributed to the high oxygen pressure affecting the structural properties at the surface of the film during deposition, leading to a reduction in crystallite size [17].
This can be explained by a reduction in the film thickness with the increase in the oxygen percentage.
Therefore, the observed reduction in carrier concentration at higher oxygen percentages can be interpreted as a consequence of the reduction in oxygen vacancies [28].

Related previous studies The increasing competition in the modern manufacturing sector has led to a greater concern about cost reduction, product quality increasing and, increasingly, reduction of the time between concept and production.
Future computer-aided design (CAD) systems must have a data structure that allows the user’s access to low-level and high-level geometric entities.
In this paper, an approach for the map data structure was used in the implementation of the graphs.
The graph map data structure was implemented combining other generic data structures like a vector, map and list structures.
The practical implication of the results can be observed and proved when we find the assembly functional chains from the assembly graph data structure.
