The suggestion is put forward that adopting the different geometry control condition between rolled h - section steel beam and general i - section steel beam 本文提出軋制h型鋼的幾何控制條件,并建議將一般工字形截面簡(jiǎn)支梁和軋制h型鋼梁分列處理。
Based on the gb50017 code , the geometry control condition of integral stability capacity of homemade rolled h - section steel beam is conservative excessively and is modified accordingly 本文得出精度更高、適用范圍更廣的計(jì)算簡(jiǎn)化式。 gb50017關(guān)于梁的整體穩(wěn)定幾何控制條件對(duì)國(guó)產(chǎn)軋制h型鋼過于保守。
The paper is concerned with the control strategies of uncertain nonlinear systems and the application on the ac speed adjustable systems . its main contents includes neural network control , differential geometry control and algebra control 本文研究了非線性系統(tǒng)的控制策略及其在交流傳動(dòng)中的應(yīng)用,主要的內(nèi)容涉及三個(gè)方面:神經(jīng)網(wǎng)絡(luò)控制、微分幾何控制和代數(shù)控制。
