In order to achieve the design goal , exhaustion and carbonating procedures need to be modified and perfected , uniformity of anode - grid space distance and grid surface treatment procedure need to be improved 為了完全達(dá)到設(shè)計目標(biāo),尚需對試制過程中的排氣與碳化工藝進(jìn)行調(diào)整和完善、提高陽柵空間距離的均勻性以及改進(jìn)柵極表面處理工藝。
We generated its grid surface on the fuselage or missile body according to the geometry projection relation between aerodynamic components and the bilinear interpolation approach . finally , we successfully developed a new algebra grid generation technique in virtue of the improved four - boundary interpolation . in this thesis , we put emphasis on the researches of aerodynamic inverse design and drag reduction questions for airfoil and wing using euler equations and control theory proposed by jameson ( 2 )進(jìn)行了應(yīng)用控制理論和二維歐拉方程的翼型氣動反設(shè)計,以及有升力約束情形下翼型跨音速減阻問題研究,分別推導(dǎo)了相應(yīng)的共軛方程及邊界條件的數(shù)學(xué)形式,并給出了相應(yīng)的梯度求解公式形式,研究發(fā)展了共軛方程及梯度的數(shù)值求解方法,成功進(jìn)行了多個翼型的反設(shè)計和減阻問題研究。
This project which is based on the demand of increasing the electron tube ’ s qualities totally and reducing the manufacture cost has done a large amount of investigative work as follows to improve and perfect the technologies for the important part of electron tube manufacture ? the grid surface processing : on the surface processing of the molybdenum grid , the primary purpose is to reduce thermionic emission and secondary electronic emission of the grid . by the constantly experiment and grabbling the different technology routes , we have successfully developed these new technologies on the tac and zrc electrophoresis and electroplating platinum black of the grid , and made its surface cladding quality very stable and reliable 本課題是基于整體提高電子管的質(zhì)量和降低生產(chǎn)成本的要求,對電子管生產(chǎn)中的重要部分? ?柵極的表面處理技術(shù)進(jìn)行改進(jìn)和完善,主要在以下方面進(jìn)行了深入研究:在鉬柵極表面處理方面,主要為實(shí)現(xiàn)降低柵極的熱電子發(fā)射和二次電子發(fā)射,通過不同工藝路線的不斷試驗(yàn)和摸索,成功開發(fā)出柵極電泳tac 、 zrc和電鍍鉑黑的新工藝,使柵極的涂覆質(zhì)量穩(wěn)定可靠。
