Based on the analysis of the kinetic track of the scallion during planting, basic relationships ' among the characteristic parameters of the transplanter with two flexible metal disks, including the velocity of the transplanter, the rate of transplanting, the spacing between seedlings, the angle of releasing seedlings, the diameter and length of seedlings, have been set up in this paper, and then a mathematic model of optimum design for the transplanter with the final planting angle of seedlings ( y = 90 ) has been formulated and solved with good results. according to the optimum solutions, a new type of transplanter with two flexible metal disks has been developed and the field tests of the transplanter have been conducted
為了實現大蔥機械化移栽，作者分析了國內各種移栽機的結構特點，確定了以撓性圓盤式栽植器為研究對象，在分析撓性圓盤式栽植器的運動軌跡和特徵參數的基礎上，完整地確立了撓性圓盤式移栽機的基本參數：栽植頻率、栽植株距、機組前進速度、輸送帶上秧槽的間距、撓性圓盤半徑、撓性圓盤的轉速、夾苗株數以及傳動比之間的相互關系，並建立了以蔥苗栽植傾角= 90為目標的優化設計數學模型，提出了撓性圓盤式大蔥移栽機的優化設計方法。 -
In chapter two, according to n - s equation, considering the couple between liquid and solid, the double - fluid model is used to respectively set up momentum equations of two - phase fluids in condition of basic hypothesis, which are general equations of two - phase fluids. simplifying the equations in boundary layer, the momentum differential equations are required and the boundary conditions are given. in the same time, the simplifying equations and their solutions, in which solid grain satisfies in boundary layer
第二章依據n - s方程，考慮到液、固之間的相間耦合，在基本假設條件下，採用雙流體模型，分別建立液、固兩相的動量方程，它是固液兩相流體的一般方程式；對其在邊界層流區內進行量級比較，得到邊界層動量微分方程並給出其邊界條件，同時也得到固體顆粒在邊界層內所滿足的簡化方程及其解的表達式。 -

Fde and dde have been extensively developed since 1959, and each branch has been set up a complete theory system. now, more and more scholars study fde and explore further developments. also, fde with infinite delay is one of the fields of great interest to people. in fact, fde with infinite delay has undergone a rapid development since 1870s. hale and kato gave a normal and set up the b phase space theory in 1978. under the basic theory, people studied the stability, boundedness and periodic solution of rfde. for example : in [ 4 ], huang qichang introduced the concept of uniformly forgetful functional, discussed the boundedness and stability of solution ; [ 5 ] - [ 8 ] discussed the existence of periodic solutions, generalized the results of rfde with finite delay. however, for nfde with infinite delay, few people discuss it, and many problems have not been solved. so there are some very interesting developments. lt is worth while generalizing the results of fde with fini te delay or rfde with infinite delay to nfde with infinite delay. because of the difficulty of infinite delay, we may discuss neutral volterra integro - differential equations, and obtain simple results
自1959年以來，無論是一般的泛函微分方程還是具體的微分差分方程，其發展是非常迅速的，在每一分支中都形成了一套完整的理論體系，如今越來越多的學者涉足這一領域探求更新的發展，無窮時滯泛函微分方程就是他們研究的主要對象之一。準確地說，無窮時滯泛函微分方程興起於19世紀七十年代， 1978年hale與kato提出b空間的公理體系。在此體系下建立了方程的基本理論，並研究了解的穩定性、有界性、周期解等問題，如[ 4 ]利用一致健忘的liapunov泛函討論了解的有界性和穩定性， [ 5 ] - [ 8 ]討論了周期解的存在性，推廣了有限時滯的相關結果。 -
