The order of the scale value used is the study of a particular order corresponding. For example, to the upper social strata, the upper, middle, lower middle class, the next lower layer, etc. are labeled respectively "5,4,3,2,1" or "3,2.5,2,1.5,1" belongs to this category. Which represents only the upper layer 5 and the representation of the gap between the top four, and represent the upper 4 and 3 indicates the difference between the middle, is not necessarily equal. 5,4,3, etc. are added to the list of any symbol, if recorded as 100,50,10 it anyway. The numeric scale spacing used, not only that the amount of how much has the object to be measured, said the size of the extent of their size, that is the interval. However, the origin of this scale can be arbitrarily set by the hydraulic motor test, but it does not mean that the amount of that thing is "no." For example, O ° C is the absolute temperature 273 ° K, F 32 ° F. Qualitative analysis is the main virtue of folding the analyst's intuition, experience, with the object of analysis of continuation of past and present situation and the latest information, the analysis of the object's nature, characteristics, development of a method to determine changes in the law to make. In contrast, the former method is more scientific, but requires a higher depth of mathematical knowledge, while the latter method, though more rough, but the data were insufficient or analysis mathematical foundation is weak when more suitable, more suitable for general investors and economic workers. But it must be pointed out that the hydraulic motor, two methods of mathematical knowledge requirements, although high and low power source of the hydraulic motor, but it does not regard the qualitative analysis and quantitative analysis distinct from open. In fact, modern qualitative methods also have to be calculated using mathematical tools to repair the hydraulic motor, while the quantitative analysis must be established on the basis of qualitative prediction, the two complement each other, based on qualitative and quantitative, qualitative and quantitative is specific, a combination of both up flexibly in order to achieve the best results. Repair of hydraulic motors, hydraulic motors, hydraulic preferred by the Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd.
