The wind rates of roots blower with these various kinds of three - lobe circular arc rotor are calculated and comparison between their performances is carried out. it is found that three - lobe rotor with external - internal circular arc and cycloid can produce the largest air volume. comparing the air pulsation produced by cylinder rotor and helix rotor, and proof that the structure of helix rotor can reduce the noise of roots blower
本文給出了羅茨鼓風機三種不同的圓弧轉子型線的參數方程（外圓弧及其包絡線型、內圓弧及其包絡線型、和內外圓弧加擺線型） ，還給出了這三種轉子的徑距比（ r _ a a ）的極值，並進行比較，得到：內外圓弧加擺線線型是最優線型這一結論；為降低羅茨風機的噪聲，將傳統的直葉轉子改成扭葉轉子。 -
In the chapter 3, we study the t - blocking set and ( k, r ) - arc in the pg ( 2, q ). first we give ball " s theorem an elementary proof and improve its result, then we prove a new value of mr ( 2, q ). in the chapter 4, the upper bound of the caps is our main research
在第三章里，我們主要研究的是平面t - blocking集和（ ， ） - arc ，其中對給出了t - blocking集的一個下界值的ball定理進行了初等證明並改進了其結果；另外，我們還研究了平面（ ， ） - arc ，其主要結果是證明了一個新的m _ r （ 2 ， q ）值。
