The significant characteristics of the new afm include : ( i ) it has a horizontally designed probe unit , and the direction of cantilever ' s weight was perpendicular to the atomic force , thus the effect of cantilever ' s weight on the imaging quality can be effectively avoided ; ( ii ) it owns a particular path of optical beam deflection method for the measurement of cantilever ' s displacement 臥式afm探頭系統(tǒng)的顯著特色是,微懸臂重力與原子力方向相互垂直,有效地避免了重力對(duì)微懸臂及成像質(zhì)量的影響,從而在設(shè)計(jì)方法上保證了afm的性能。本文在方法上的另一創(chuàng)新是,發(fā)展了獨(dú)特的微懸臂偏轉(zhuǎn)量的光束偏轉(zhuǎn)法檢測(cè)系統(tǒng)。
And , we also have had the relation between the size of the horizontal circulation regions and the fr number around the dike for the flow - deflection method . the results of this study show that , using the method of flow - deflection or " sucking - spouting " water , the flow pattern can be improved , the size of the horizontal circulation regions and the sedimentation volume caused by the horizontal circulation can both be reduced . so , they can be adopted to improve the navigation condition of upper approaching channel of three gorges project , which could guarantee the safety of navigation 通過(guò)試驗(yàn),得到了以下創(chuàng)新的成果: 1 、不加吸、噴水時(shí),丁壩后的回流長(zhǎng)度約為丁壩長(zhǎng)度的8倍; 2 、加吸、噴水可以減小丁壩后的回流尺度和強(qiáng)度,并得出了有理論根據(jù)的吸、噴流量與回流尺度減小之間的定量關(guān)系以及吸、噴流量與丁壩周圍流速梯度之間的定量關(guān)系; 3 、加吸、噴水可以減小回流淤積,并得出了吸、噴流量與淤積量減小之間的定量關(guān)系以及回流尺度減小與淤積量減小之間的定量關(guān)系; 4 、加導(dǎo)流板可以減小丁壩后的回流尺度,并得出了丁壩周圍的水流fr數(shù)與回流尺度減小之間的定量關(guān)系。
An explicit formula of ultimate strength is achieved according as combination of elastic large deflection method and rigid plastic method for perfect plates . 2 . the explicit formulae with damage parameters as variable of reduction factors for ultimate strength of damaged plates are achieved by curve fitting based on a mass of numerical computation for parametric imperfection and damage of plates 將板格的各種缺陷和損傷形式參數(shù)化,通過(guò)大量數(shù)值計(jì)算擬合出受損板格極限強(qiáng)度折減系數(shù)的以損傷參數(shù)為變量的顯式表達(dá)示,用折減系數(shù)對(duì)完好板格極限強(qiáng)度進(jìn)行折減得到受損板格極限強(qiáng)度公式。
