Yttrium tungsten is primarily used in military and aviation industry with narrow arc beam , high compressing strength , highest welding penetration at medium and high current 在焊接時,弧束細長,壓縮程度大,在中大電流時其熔深比較大。目前主要應(yīng)用于軍事工業(yè)和航空航天工業(yè)。
On basis of the data of unlimited compress strength experiments , the paper gets the relationship between unlimited compress strength of lime - soil and the quantity of added lime . the paper also discusses the reason why the lime can dispel the expansive and shrink quality of expansive soil 通過無側(cè)限抗壓強度試驗,得到石灰土無側(cè)限抗壓強度與摻灰量的關(guān)系及齡期對石灰土無側(cè)限抗壓強度的影響,同時對石灰改善膨脹土的機理作探討。

The fastened end of bar was machined to multi cone - shaped heads . through the cone heads compress the inorganic anchoring material , the load was transmitted from bars to base material . it changes the transfer path of loads and takes advantage of high compress strength of inorganic material , thus enhanced the anchor intensity of inorganically post - installed bars 本文提出一種新型的植筋技術(shù)? ?帶錐頭無機植筋,它把鋼筋錨固端加工成多個錐頭,通過錐頭對無機錨固材料的擠壓,將荷載傳遞給基材,使基材與無機錨固材料的界面上產(chǎn)生剪壓復合應(yīng)力狀態(tài),改變傳統(tǒng)植筋的受力機理,利用了無機錨固材料抗壓強度高的特點,從而提高了無機植筋的錨固強度。
