Petrochina group has gradually formed an integrated reach and development system for more than 50 years, and taken the leading in the field of the petroleum science and technology in the world such as geology theory of land, oil and gas and bigger - scale non - equal gritstone oil field development, however, the technology gap is as a whole obvious compared with the overseas bigger - scale oil corporation and technology service corporation ; in addition, the current development & administration system ca n ' t meet the need of the development of the corporation
中油集團經過50多年的發展，形成了完整的研究開發體系，在陸相油氣地質理論、大型非均質砂巖油田開發等多項石油科學技術方面居世界領先水平，但總體技術上與國外大油公司和技術服務公司相比還有很大差距，現有研究開發組織管理體系不能滿足公司發展的需要。 -
The paper establishes mathematics model of electromagnetic heating system of eddy current field and temperature field, and gives corresponding discrete format with elements as eight nodes, hexahedron equal cell, through calculating eddy - current field to gain the internal heat source that the temperature field needed, to use discrete method to solve the problem of induction - heating part ' s temperature field by axial symmetrical electromagnetic, and then to analyze the characteristic of instantaneous temperature field
本文建立了電磁加熱系統的渦流場和溫度場間接耦合的數學模型，分析了不同頻率下渦流和溫度的分佈情況，並以八節點六面體等參元為例給出了渦流場對應的離散格式，通過計算渦流場獲得溫度場所需要的內熱源強度，加熱部件的溫度場以軸對稱格式進行離散求解，並對瞬態溫度場有限單元法的求解特點進行了分析。 -
After a long time evolution, the system finally reaches a stable state at which the magnetization and the equal time spin - pair correlation are periodic oscillating functions with the equal period as the external field. numerical simulation shows : when the amplitude of external filed is large, there exits a particular temperature at which the average magnetization and the average spin - pair correlation are almost unaltered with various field amplitude ( i. e. magnetic susceptibility is zero ), and the particular temperature depends on the number of the spin states, cutting down with q increasing
由數值模擬得到：當外場幅度較大時，存在一個特殊的溫度點（我們稱之t ） ，在這個溫度點，系統的平均磁化強度和平均等時自旋對關聯隨外場幅度的變化幾乎保持不變（即磁化率為零） ，並且這個溫度的大小依賴于自旋態數目q的變化， q越大，這個溫度就越小；而當外場較小時，確信系統存在有限大小的臨界溫度 -
In the context of quantized electromagnetic fields, it seems natural to also investigate the spatial properties of the field if the harmonic oscillators associated with the normal modes of the system are prepared in squeezed states. in 1975, two japanese scientists claims the thermal field dynamics theory, which can make a thermal mechanics statistical state equal to a pure state
將熱力學統計狀態中等效成一個純態來研究，是1975年日本的兩位科學家takahashi和umezawa在他們的熱場動力學理論（ thermalfielddynamicstheory ）中所提出的。
