The invention relates to an azo dye compound and the application thereof. The compound is the combination of at least two dyes with A in the general formula (I) selected from any structure of (a), (b)or (c); any combination with A to be at least one from (a), at least one from (b) or at least one from (c); or the combination of at least one dye shown by the general formula (1) and at least one general disperse dye, or / and a dye as shown by the formula (2). Each substituent is shown as the claim of right. The compound can dye polyester and blended fabric thereof under the condition of strong alkalinity with pH more than or equal to 11 and less than or equal to 14; the alkalinity condition can effectively remove slurry and oil on the fabric, and overcomes the defect that decomposition products can be separated out in an acid bath, and cause dyeing defect. The cloth and the fabric adopting the azo dye compound are neat and have excellent styles. In addition, the polyester fiber and the blended fabric thereof can be pretreated with alkalinity and be dyed in a bath and at one step, thus improving the efficiency, and reducing the manufacturing cost and the waste water from dyeing.

The invention discloses a system for monitoring complicated oil deposit flooding conditions, comprising an input unit, a multi-level processing unit and a display unit, wherein the input unit is used for inputting well point geologic parameters; the multi-level processing unit is used for building hidden geologic characteristic parameters according to the well point geologic parameters input by the input unit, finishing multi-layer, multi-well, multi-phase and multi-driving power energy balance analysis and calculation of a block, further building an injecting and extracting correspondence relationship among wells and carrying out comprehensive inversion treatment on the layered and partitioned flooding conditions by using improper functions to obtain distribution data of various sucking sections and layered flooding conditions of the block and a single well in different periods; and the display unit is used for displaying the injecting and extracting correspondence relationship amongwells, built by the multi-level processing unit, and the obtained diagram result data of the distribution of the various sucking sections and the layered flooding conditions of the block and the single well in different periods. The system can obtain accurate layered flooding condition data and different levels of section analyzed result data, improve the extracting precision, and save the manpower and material resources.

A transversely arranged production stream line for manufacturing the case-type steel members features that the cutting unit, assembling unit, welding unit, end face milling unit, marking out unit, great assembling-welding unit and rust-removing and coating unit are sequentially arranged in the direction of stream line, their working directions are perpendicular to the direction of stream line, and the longer direction of workpiece is perpendicular to the direction of stream line. Its advantages are short length of stream line, high productivity and low cost.
