circle criterion
解釋
循環準則-
The computer acquires the image of dial gauge by high precision ccd video, after that the computer will process the dial gauge image by some image - processing algorithms such as image segmentations, edge searching, area segmentations and locating the pointer by the " circle ". at last the computer will recognise the dial pointer position and work out the precision of dial gauge in accordance with nation criterion of dial gauge. this study presents several optimum algorithms to realize quick recognition of the pointer and calibration lines of detected dial and improve the accuracy and real time quality of detecting
本系統由計算機控制步進電動機的運動，進而驅動指示表表針的運動，通過高精度ccd攝像機實時獲取表盤圖像數據，同時進行表盤圖像的相關處理，包括閾值分割、邊緣檢測、圖像銳化以及區域分割和定心圓檢測等，最終快速識別出表盤指針所處位置，最後根據國家指示表類檢定規程所制定的演算法檢定出指示表的各種精度，本系統所採用的圖像處理演算法運算量少，速度快，從而大大提高了系統的實時性。 -
The stability of the feedback interconnection of a linear stable system and a bounded perturbation is studied in time domain in this paper. it s shown how a complex system can be characterized by integral quadratic constraints. and the iqc s theory in the time domain is given. for such model, a sufficient condition for the stability of the feedback interconnection is obtained, in some cases, this condition is also necessary. as the applications of the result in this paper, the problem of absolute stability is considered, then the timevarying circle criterion and other stability criteria are given
在時域內研究了由一個穩定的線性系統和一個有界因果系統所構成的反饋內聯系統的輸入輸出穩定性問題，給出了時域內的iqc的理論框架，得到了判定反饋內聯系統穩定性的一些判據，同時也得出了一些必要條件。最後，作為前面結果的一個應用，將所得的結果應用到絕對穩定性問題中，得到了時變的圓判據和其他的一些穩定性判據。 -
Stability for a class of nonlinear feedback system is studied in this paper. thus some sufficient and necessary conditions are given. these results are suitable for both time - invariant and time - varying systems. as an application, the general time - varying lur e problem is studied too. then the time - varying circle criterion in the siso case is given. at the same time, in the mimo case, a stability criterion is given, which doesn t need the decoupling conditions
-穩定性問題，給出了其穩性分析準則和一些必要條件，這些結果適用於時不變與時變系統。其次，利用已有的結果，研究了非線性環節具有扇區特性的穩定性問題。在單輸入單輸出siso的情況下，給出了時變系統的圓判據。 -
Combining with the unique life circle of the new economic companies, the article suggests that surplus record should be substituted by operation revenue as core criterion of ipo and delisting consecutive deficient companies should be substituted by assets - beneath - debt criterion. then through analyzing the contribution ratio of the different transaction institution and combining the current situation of our capital market, this article points out that a mixed transaction combining market - maker institution with instruction - driving institution
同時，因為文章對上市制度和交易制度的分析，注重的是理論上的創新和探求，所以對上市制度關注的是決定其核心理念的上市標準選擇，對交易制度關注的核心交易方式的選擇，而對于其它上市和交易程序的具體安排只是簡述觀點。
