  1. Aiming at the problem that the seeds picked up by the suction plate of the seed metering device cannot accurately fall into the seed pit opener as well as into the seed pit, an innovated seed metering device on which the seed dropping angle can be adjusted within a certain range and a new testing stand have been developed in accordance with the mathematical calculation model that had " in accordance with the mathematical calculation model that had been established previously. then an experimental study is conducted and the seed dropping law has been found out through the study

    本論文根據2bqm - 2型氣吸式精量鋪膜播種機的結構和工作原理，針對該機在實際播種中，吸種盤吸出的種子不能滿足準確地落入在膜上滾動開穴的鴨嘴內，並及時地排入到鴨嘴所成的穴孔內的設計要求，進行了一定的試驗研究，利用已建立的計算數學模型，設計新的試驗臺，改進排種器，使排種器的落種角度可以在一定的范圍內調整。
  2. Ir, sem - edx, and water contact angle measurements on polysilane and polyacrylate film obtained by double operations and single operation showed that the influence of weight ratio of polymers, the molecular of pmma on film structure was great. the film translucence dropping while the ratio of pmma / pmts grew and the compatible reducing while the molecular of pmma increased

    通過測定所配製的系列濃度聚合物甲苯溶液、 thf溶液的表面張力發現：有機硅聚合物溶液的表面張力值在有機硅聚合物濃度低於30時變化不明顯；而甲基丙烯酸酯聚合物溶液表面張力值隨甲基丙烯酸酯聚合物濃度的變化比有機硅聚合物溶液明顯。
  3. The testing result shows that there is a difference actual seed dropping angle and the one acquired by calculation, therefore, a formula for the calculation of seed dropping angle even closely suited to production practice has been driven out and a theoretical basis for the application of 2bqm - 2 model plastic film mulch pneumatic precision planter in practical production is advanced in this paper

    通過試驗，找出種子的落種位置規律。通過試驗結果分析，找出種子的實際的落種角度和計算的落種角度之間的差別，推導出更適合實際生產中所需要的落種角度，為2bqm - 2型氣吸式精量鋪膜播種機在實際生產中的應用提供了一定的理論基礎。
  4. Along with the progress of drilling technology, many new types of bha such as steering motor assembly, dropping assembly with eccentric bend sub, dropping assembly with flexible connection are developed based on common building, dropping and holding assemblies. for using these bha, a new mathematical model is put forward for 3d static analysis of these types of bha under small deflection. and its weighted residual solution is given. the mathematical model includes ( 1 ) differential equations ; ( 2 ) boundary conditions at drill bit, stabilizer, bend angle, diameter change, tangential point and borehole wall ; ( 3 ) lateral forces and deflection angles of bit. the software based upon this method runs well

    為了更好地應用各種新鉆具，建立了適用於對普通下部鉆具、導向鉆具、帶偏心彎接頭和柔性接頭的下部鉆具進行三維小撓度靜力學分析的數學模型，包括（ 1 ）微分方程； （ 2 ）鉆頭、穩定器、彎角、變截面、切點和井壁的邊界條件； （ 3 ）鉆頭的側向力和鉆頭轉角.給出了該模型的加權余量解.用該方法編寫的軟體應用效果良好
