A timing analysis apparatus has a block simulation information storing section, a SPICE deck generating section, and a feedback-based static timing analyzing section. The block simulation information storing section stores simulation information for each block when performing circuit analysis by partitioning a circuit into blocks, the SPICE deck generating section generates a SPICE deck by interconnecting the blocks, for a path that needs analysis, by using a result of static timing analysis and using simulation conditions for the each block. The feedback-based static timing analyzing section causes a result of the simulation performed using the generated SPICE deck to be reflected in the static timing analysis.

The invention discloses an automatic identification method of weed, including: using pickup camera on the farm machine to collect the real-time images of plant which need to be analyzed in the field, and transmit them into the computer on the machine. The computer stores the images comparison standards from a large number of crops and weeds with application of statistical methods, which is compared with the image of plant that needs analysis though identification method, and determines whether the plant is crop or weed according to the result of analysis, and then control the spraying machine will spray drug aiming at the weed according to the result of comparison. The invention can identify the crop and weed well, and spray drug to the weed exactly according to the distribution, to save pesticide and reduce environment pollution.

The invention discloses a fuzzy clustering-based low-voltage distribution network station area clustering method, which includes establishing characteristic indicators of the low-voltage distribution network station area; inputting characteristic index data to be analyzed to construct an original data matrix; and standardizing the original data matrix , to obtain the fuzzy matrix, according to the Euclidean distance method, construct the fuzzy similarity matrix of the fuzzy matrix; establish the fuzzy equivalent matrix, convert the fuzzy equivalent matrix into its equivalent λ-cut matrix, form a dynamic clustering diagram, and realize the low pressure to be analyzed The clustering analysis of the distribution network area, according to the analysis requirements, outputs the clustering results of the low-voltage distribution network area after determining the classification number; according to the clustering results of the low-voltage distribution network area, the data characteristics of each category of the area are analyzed. Analyze and judge whether various types of Taiwan areas urgently need governance, screen out those areas that urgently need governance, and give a preliminary follow-up governance plan. The method of the invention has the advantages of fast recognition speed, high classification accuracy, high classification efficiency and the like.
