循环理论

This truth is obscured by the business cycle, which causes revenues and margins to fluctuate, and by the vicissitudes of investor sentiment, which cause shares to be derated and rerated (the dividend yield to rise and fall).

和利润水平由于商业周期循环上下波动，投资者情绪的阴晴导致股票下跌和，这样一来，上文提到的理论就变得复杂晦涩起来。

MWM engine makes the conversion among two-stroke mode, four-stroke mode and six-stroke mode of one engine come true in theory, filles in the blank with 1/3 which is the ratio of total strokes to working strokes in single working cycle of engine, possessing the continuous variable compression ratio of a certain range at the same time, combines the advantages of two-stroke engine and four-stroke engine, expandes the working range of engine greatly.

MWM发动机在理论上实现了一台发动机在二冲程、四冲程与六冲程工作模式之间的相互转换，填补了发动机单工作循环作功行程数与总行程数比值中1/3的空白，同时具备一定范围连续可变的压缩比，整合了二冲程与四冲程发动机的优点，拓展了发动机的工作范围。

Three theories dominate:(1) it is being dissolved in the ocean, and then it precipitates to the sea bottom as carbon rain; or (2) it is being deposited in soils by microbes; or (3), most controversial, the lost carbon is fueling growth of the world's savanna grass, or being turned into tree wood, on an imperceptible but massive scale that we haven't yet been able to measure.

其中有三个理论作为主导：(1)被海洋溶解了，最终作为碳雨沉到洋底。(2)被微生物降解到泥土中。(3)最具争议的，消失的碳变成了热带草原，或者成了树木，以一种我们未曾察觉但是却很容量很大的循环存在。

This study mainly focused on the water resource and environmental crisis, which are all caused by agricultural irrigation in Inner Mongolia irrigation area. Based on the balance of total water quantity between ground water, underground water and soil water, a study was made on the water quantity varieties in the headraces and offtakes, and the affection of the water cycle under the human activities was quantitively caculated.

针对引黄灌区所面临的水资源问题及灌溉引起的环境问题，以内蒙古河套灌区为研究对象，从灌溉引水、用水、排水之间的转化关系为切入点，以地表水、土壤水和地下水之间的水量平衡理论为基础，定量研究河套灌区在人类影响条件下的水循环特征。

Three main shortcuts are listed out: the first is the data can t be collected easily which holdbacks the statistics and analyses; the second is the system s extension and adaptability are poor and the data structure and code are redundant; the third is the communication of the same kind management information system is weak and the communication risks on some danger.

本文着重从解决这三个方面的问题入手，提出了&柔性&管理信息系统的模型，着重讲述了系统设计的方法和理论，并给出了&柔性&管理信息系统的定义，以及系统的基于组件的设计范式，体现了使用者既是开发者的主题思想，利用面向对象的循环迭代式软件设计方法，通过对模块间的耦合度和模块内聚合度的分析，来验证系统的科学与先进型。

Based on the present situation of comprehensive resources utilization of mine water,fly ash, slag ,kaoline and coal gangue,according to relative theories about circular economy,we analyzed the technological process of comprehensive utilization of resources of Xuzhou Mining BusinessGroup Co Ltd.

本文从研究徐州矿务集团对矿井水、粉煤灰及灰渣、高岭土及煤矸石的综合利用现状入手，结合了循环经济的有关理论，分析了徐州矿务集团的资源综合利用的技术路线。

Chapter 2: Analysis the reasons and character of fatigue damage in long-span bridge.

第二章从理论上探讨结构疲劳破坏的原因，结构承受循环应力是影响结构抗疲劳能力的主要因素。

The proposed method can work well under asymmetry element parmeters,and it is not necessary to consider the phase shift of ideal transformer or using multi-port net theory,which make the proposed method more applicable and simplify the calculat...

相分量算法不要求电力系统元件参数对称或循环对称、不利用多端口网络理论及理想变压器的移相，拓宽了故障计算的适用范围、简化了编程难度，并可推广到处理诸如线路换位不完全的参数不对称等其他电网不对称计算。

The proposed method can work well under asymmetry element parmeters, and it is not necessary to consider the phase shift of ideal transformer or using multi-port net theory, which make the proposed method more applicable and simplify the calculation program. The method is also capable of handling various unsymmetrical calcuations, such as the fault calcuation for power system without complete transposition.

相分量算法不要求电力系统元件参数对称或循环对称、不利用多端口网络理论及理想变压器的移相，拓宽了故障计算的适用范围、简化了编程难度，并可推广到处理诸如线路换位不完全的参数不对称等其他电网不对称计算。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
