The form of variable cross - section , used mostly in the practical projects , just has the change of the linear variation on the height of the web plate while keep the width of the flange c hangeless 實際工程中使用最多的變截面構件形式是僅構件腹板高度線性變化,翼緣寬度保持不變的形式。
With the different use , the height of the web plate and the width of the flange can be designed to be the form of linear variation respectively or synchronously , as well as the thickness of the flanges can be taken with the different values 根據(jù)需要的不同,可以將腹板高度和翼緣寬度分別或同時設計成沿桿長線性變化的形式,并且上下翼緣的厚度可以根據(jù)需要取不同的值。
By analyzing the eigenvalues of linear variation equations , some algebraic criteria for the absolute stability ( independent of the delays ) are established for two special 3 - dimensional systems . also , the sufficient conditions under which the systems hold a hopf bifurcation are obtained , which are easy to verify 我們通過分析特征方程的特征根,獲得了平衡點絕對穩(wěn)定的代數(shù)判據(jù),同時得到系統(tǒng)存在hopf分支的充分性條件,這些判據(jù)在實際中易于驗證。
The harmonic factor raises with the growth of volume percentage of hardening particles no mater what detecting direction is . but it is not a linear variation course . the harmonic factor mounts up slowly under the critical value but increases rapidly while exceeds the critical value 在正、逆向檢測時,隨著強化粒子體積百分數(shù)的增加,在有效頻帶范圍內(nèi)諧波系數(shù)同時單調(diào)增加,但其變化是非線性的,即在臨界值以下,諧波系數(shù)的變化趨于平緩,而超過臨界值以后,隨著強化相粒子體積百分數(shù)的增加,諧波系數(shù)快速增加。
