One means of controlling the heat flux is by optimising the grinding parameters which generally results in the use of conservative material removal rates.
It is expected that the heat flux to the chips is high enough to raise the chip material close to the melting point of the workpiece material.
By increasing the depth of cut and feed rate (or specific material removal rate), the C-factor and Fr ratio can be reduced.

China's great development of LTMI has expanded its scale of import &
export as well as of use of foreign investment, brought enormous demands for labor force and raw
materials, driven domestic employment, and promoted sustainable economic growth.
Index Determination and Data Collection Horizontal evaluation covers 25 industries (as shown in Table 1), and the reference system based on indexes in China Statistical Yearbook on Science and Technology 2008 is used to guarantee that inter-industry values are comparable.
Name And Code Of Chinese Ltmi Code Name of Industry Code Name of Industry H1 Farm products and by-food processing H14 Raw chemical materials and chemical products H2 Food production H15 Chemical fiber H3 Beverage production H16 Rubber products H4 Tobacco products H17 Plastic products H5 Textile industry H18 Nonmetal mineral products H6 Garments, shoes and hats production H19 Smelting and pressing of ferrous metals H7 Leather, furs, feather (down) and related products H20 Smelting and pressing of nonferrous metals H8 Timber processing, bamboo, cane, palm, straw products H21 Metal products H9 Furniture manufacturing H22 Ordinary equipment H10 Papermaking and paper products H23 Special equipment H11 Printing and record medium reproduction H24 Transportation equipment H12 Cultural educational and sports goods H25 Handicraft and other production H13 Petroleum, coking and nuclear fuel
This indicates that China should strengthen its input of innovation resources in the above three industries to realize more output; As to the following 14 industries, namely, H2: Food production; H3: Beverage production; H5: Textile industry; H6: Garments, shoes and hats production; H10: Papermaking and paper products; H13: Petroleum, coking and nuclear fuel processing; H14: Raw chemical materials and chemical products; H15: Chemical fiber; H17: Plastic products; H18: Nonmetal mineral products; H19: Smelting and pressing of ferrous metals; H20: Smelting and pressing of nonferrous metals; H21: Metal products; and H23: Special equipment, they fail to achieve optimized resource allocation and have decreasing returns to scale, which shows that they are facing the problem of innovation resource waste, and they only obtain comparatively small increase in output by enlarging input scale.

Nanostructured transition metal oxides are considered as excellent materials in terms of achieving high specific capacitance in ECs.
Therefore, efforts have been devoted to disperse nano ruthenium oxides on porous materials to decrease the cost of electrode materials in ECs [2].
Activated carbon (AC) is one of the porous materials because of its unique surface characteristics.

The MR-sensitivity of these materials can be comparable with that in permalloy films but in a wider range of magnetic fields.
To minimize the error in the step height measurements caused by different optical constants of a substrate and a deposited material, the same material was deposited twice.
The first layer of the material is used as a bottom layer with a thickness of 600 Å.
The work is supported by the Program of the Presidium of Russian Academy of Sciences, grant No. 27, and Russian Foundation on Basic Research, project No. 10-02-00590.

Abstract.
The former has difficulties in removing gate freezing material, and the latter is much more complex than the previous structure.
The separable contact surface that is used to take out products and freezing material is called parting surface.
SM1 was selected to be the concave die material.
