最全面的双色球定位+和值+大底+余数分析

断组手动过滤表格，如果你有断组跟踪表格，即可用它配合过滤。只支持3-3-4形式的断组，将数数据按"147-258-0369"或"147,258,0369"的格式复制入数字录入区，设置好容错，点“大底”即可

A 9216 x 9216 active element solid state Charge Coupled Device (CCD) Full Frame sensor. The CCD is intended for advanced scientific, space, and aerial reconnaissance applications. The CCD 595 is organized as an array of 9216 horizontal by 9216 vertical imaging elements. The pixel pitch is 8.75um with a 100% fill factor. Three-phase clocking is employed in the imaging area with two-phase clocking in the serial readout registers. Image readout is performed via 4 serial registers containing 19 isolation rows between imaging and readout sections. The imaging array can be clocked unidirectional (4-output configuration) or bidirectional (8-output configuration). The imaging area segments are split in mid-array for the latter configuration. To maximize the exposure/readout cycle rate, concurrent array and serial register clocking is utilized. Fast transfer clocking between the array and serial registers is accomplished with strapped transfer gates that load each line in less than five microseconds.
