[0017] The "range" disclosed by the utility model is limited in the form of lower limit and upper limit, and the given range is limited by selecting a lower limit and an upper limit. The selected lower limit and upper limit define the boundaries of the specific range. The range defined in this way can include or not include end values, and can be arbitrarily combined, that is, any lower limit can be combined with any upper limit to form a range. For example, if a range of 10-50 is listed for a specific parameter, it is understood that the ranges of 10-40 and 20-50 are also expected. In addition, if the minimum range values 1 and 2 are listed, and if the maximum range values 3, 4 and 5 are listed, the following ranges can all be expected: 1-3, 1-4, 1-5, 2-3, 2-4 and 2-5. In this application, unless otherwise stated, the range of values "a-b" represents a shorthand representation of any real combination between a and b, where a and b are real numbers. For example, the value range "0-5" means that all real numbers between "0-5" have been listed in this paper, and "0-5" is only a shorthand representation of these value combinations.
