And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
通過對測試數據的分析與綜合研究，並同中國和世界一般花崗巖類以及中國主要金、銅成礦巖體的花崗巖類進行對比，得出本區花崗巖類巖石具有以下特徵：屬磁鐵礦-型或同熔型花崗巖，其巖漿物質具殼幔混源特徵：主要由熔融態巖漿經結晶分異作用，通過多期變速上侵而形成；其分異演化程度較低；寄主巖基和包體具有同源性；巖石的形成溫度范圍約為500 - 700 ，壓力大約為2 . 50gpa - 4 . 35gpa ，氧逸度值1gfo _ 2為- 15 . 53 ? 14 . 00 ；該巖帶主要形成於板塊碰撞前消減的活動板塊邊緣期，為燕山至喜馬拉雅早期的大陸邊緣火山弧環境的產物。But rather than extinguishing the magnetic field completely, the reversed flux patches created a weak field with a complex mix of polarities during the transition
但在過渡期間，這些反向通量斑塊並不會完全消除磁場，而是形成一個綜合了復雜極性的微弱磁場。Chapter four : firstly, creatively puts forward the double circulation message drive programming idea, and detailedly expounds the basic theory of the double circulation message drive ; afterwards, works out the software of the electromagnetic flowmeter system according to it ; finally, works out the multi - byte decimal fixed point numbers multiplication & division subprogram, through studying the current arithmetic
第四章首先創造性地提出了雙循環消息驅動程序設計思想，並詳細闡述了雙循環消息驅動的基本原理；然後根據該思想設計出電磁流量計系統軟體；最後通過研究原有演算法設計出演算法改進后的多位元組十進制定點數乘除法程序模塊。In order to decreasing hydraulic impact, the principle is analyzed to eliminate or increase hydraulic impact by means of changing eccentric lump structure to cut down the inertia force of starting, changing the pressure of pilot electromagnetic relief valve and changing the parameters of accumulator
為了減小液壓沖擊，本文分析了用改變偏心塊結構減小起振慣性力的方式、用改變先導式電磁溢流閥溢流壓力方式和改變蓄能器參數方式消除或減小液壓沖擊的原理。A topology of asymmetrical half bridge soft switching is researched in this thesis, which has inherent zero voltage switching ( zvs ) capability and thus potentially higher efficiency by its resonating of the leakage of power transformer with the parasitic capacitances of the power mosft switches, whereas it does n ' t raise the expense of the converter these studies in the thesis have been done as follows : ( 1 ) the topology of asymmetrical half bridge is introduced, and its principle and the relation of duty cycle and input voltage and output voltage discussed, the method of eliminating the deflection magnetism is also brought forward
雖然，軟開關技術能夠實現功率變換器的小型化、模塊化等，但是，電路變得更加復雜，使得中小功率的變換器的成本增加，往往不利於商業競爭。本文研究了一種零電壓的不對稱半橋拓撲結構，它可以在不增加電路成本的基礎上，利用電路自身的特點，實現軟開關。本文所做的主要工作如下： （ 1 ）對不對稱半橋主電路工作原理進行分析，給出了占空比與輸出電壓、輸入電壓的關系以及消除變壓器偏磁的方法。Firstly, design the software phase - closed loops ; secondly, realize the double closed loops control of the instantaneous value and the virtual value. furthermore, the dynamic flux imbalance of the output transformer caused by ordinary pi arithmetic is analyzed in detail. a new solution for flux balance by sampling the instantaneous primary current of the output transformer and introducing the on - line calculated bias current component into the voltage regulation arithmetic is presented
系統軟體實現了ups的各個功能模塊，首先設計了軟體鎖相環；然後實現了輸出電壓瞬時值和有效值雙閉環反饋控制；並且在深入分析基本數字pi演算法所引起的輸出變壓器動態偏磁問題的基礎上，提出了一種改進演算法，實時消除了變壓器的偏磁。分享友人
