supply curves
解釋
供給曲線-
The traditional cobweb models are presumed that the supply and demand curves are linear and supply is equal to demand. but in practical economic system, the two hypothesises are hard to reach
傳統的蛛網模型假定供給函數和需求函數均為線性且每一期的供給與需求均衡，在現實的經濟系統中，這兩個假定條件都是難以成立的。 -
The main content is to study the stability of some cobweb models in which supply or demand curves are given nonlinear form. researches on the stability are done and the existent conditions and stable regions about equilibrium price are obtained. chapter five, application of logistic equation in cobweb models
第四章：對具體幾個蛛網模型的分析本章是本文研究的核心和重點之二，主要研究了對于供給函數或需求函數為特定非線性形式的幾個蛛網模型的動態分析與穩定性問題，分別對需求函數或供給函數為非線性函數時的蛛網模型，進行了動態分析和穩定性分析，從而得出了其均衡價格的存在條件及穩定區間。 -
The shifts that have just been illustrated in supply and demand curves show how particular relationships - particular markets - are influenced by other relationships in the economy as a whole
剛才所說的供應曲線和需求曲線的移動，表現了特定的關系（特定的市場）是怎樣受到經濟整體中其它關系影響的。 -
The demand and supply curves are rebuilt according to the two kinds of social necessary labor time. the / macro - section, including the last two chapters, deals with the problems of the wacro - operation of the mechanism of the value
第五章研究勞動價值理論為基礎的供給和需求原理，分別用「第一含義社會必要勞動時間」推導出「供給曲線」 ，用「第二含義社會必要勞動時間」推導出「需求曲線」 ，並將之與新古典的供求理論進行比較。 -
Abstract in this paper the phase commutation and current curves of brushless motor variable - speed system are studied. according to the results that the pulsating torque is influenced greatly by the ratio of the direct current supply voltage and the electromotive force of the motor, an approach to reduce the pulsating torque is presented
本文通過對無換向器電動機模型的換相過程和電流波形的研究，得到換相轉矩波動受直流電源電壓和電動機電動勢幅值的比（ u / e ）的影響較大的結論並獲取了最佳u / e ，同時通過模擬研究了電流波形，提出了減小轉矩脈動的控制策略。 -
For the whole porous bearing, the data and curves are acquired, such as, the load capacity and static stiffness versus the supply pressure, permeability, thickness of the film, eccentricity ratio and the structure parameters of the bearing. what ’ s more, some disciplinary conclusions are drawn
對于全多孔質軸承，還分析計算了供氣壓力、滲透率、氣膜厚度、偏心率以及軸承的結構參數對軸承靜態性能的影響，給出了一些規律性的結論。 -
3. characteristics to point out the essence of opportunity cost is return rate of factors, so use the opportunity cost of factors to do the benefit - cost account of agriculture products is in line with the principle of market - economy. to suggest improving the ways of the benefit - cost account of agriculture products, and put forward a new system of he benefit - cost account of agriculture products ; to calculate the shadow prices of agriculture production factors by using stochastic frontier production function and marginal productivity theory, especially acquire the shadow prices of the agriculture land ; to do the principle analysis on the supply - demand mechanism, and suggest the supply and demand curves of china agriculture production factors ; to prove the applicability of using stochastic frontier production function to research the product ion cost of agriculture products
本文研究的創新和特色之處為：指出要素機會成本的實質是要素的投資報酬率，從而認為以要素機會成本作為農產品成本收益核算的基礎概念符合市場經濟原則；提出以生產要素的機會成本概念為計價原則，以改進中國農產品的成本收益核算方式，據此提出符合市場經濟原則、體現完全生產成本的中國農產品成本收益核算項目體系；以隨機前沿生產函數方法和要素邊際生產力理論為邏輯框架直接測算中國主要農業生產要素的價格，特別時土地要素的價格；對中國農業生產要素的供給和需求機制進行理論分析，給出中國農業生產要素的供給、需求曲線；在理論上論證用隨機前沿生產函數技術研究農產品生產成本問題的適用性。
