At last , some investgation is made to change about elementary constant of the universe in today ,which demonstrates that elementary constant of the universe in today would change at a ratio of 2.3387723548904887*1050 per year which means that elementary constant of the universe in today would remain as an constant unchanged within one million years if its accuracy fix on the 4th digit after radix point of 7.7577806787995708*1060 As a reminder , both elementary constant of the unvierse elementary constant of the unvierse in today have nothing to do with the cosmic constant introduced by Mr.

基本宇宙常数是一个变化的物理常数，其数值变化的速率为：2.3387723548904887*1050 ，与今天基本宇宙常数7.7577806787995708*1060 相比较，如果在保持今天宇宙常数的数量级不变的情况下将精确度选定在小数点后第4位，那么今天基本宇宙常数将在100万年之内保持不变。

However, W addition stabilizes the phase of 〓, which can weaken the exchange coupling between the nano-grains of magnetic phases, resulting in the decrease of the coercivity and rectangularity of magnets.

另一方面，添加W能够稳定分布于晶间的富硼相〓，该富硼相削弱磁性晶粒间的交换耦合，导致磁体矫顽力降低和矩形度变差。

Afterwards, a novel control strategy is put forward. A Swept-frequency with separate and self-excitation switching is applied in starting circuit, which can look for resonant point automatically.

然后，提出一种新型的逆变控制策略，启动电路采用扫频方式自动找寻负载谐振工作点；工作状态控制采用锁相环技术和重叠角随动控制相结合的方法。

The relationship of ore-forming fluid salinity-aqueous cation lg demonstrated that water-rock reaction was also one of the potential gold deposition mechanisms besides mixing with meteoric water. All of these were consistent with that sericitization and pyritization hydrothermal alteration were extensively/intensively distributed (as high as 33%), gold grade linearly correlated with degree of alteration,∑REE depletion and δ〓O enrichment

成矿流体盐度-液相主要阳离子组分1g演化规律研究表明，除与大气降水的混合-稀释外，水-岩相互作用也可能是造成金沉淀的重要因素，这与本文所研究金矿床中绢云母化、黄铁矿化等热液蚀变广泛发育(可高达33％)，Au品位与热液蚀变程度、REE亏损量及δ〓O富集规模表现出较为明显的线性关系等一系列地质事实相吻合

Considering the speciality of the principal reciprocal susceptibility in trigonal boracite, the experiment scheme on the measurement of the principal reciprocal susceptibility components is presented. On the basis of Curie principle, the order parameter of the antiferroelectric phase transition is investigated by taking crystal PZT, crystal SrTiO〓 and the antiferroelectric models of simple cubic lattice as examples.

针对五种特殊的具有铁电三方相的方硼盐，计算出了其铁电三方相的自发极化强度、居里温度和主倒极化率等，发现自发极化在居里点有跃变；沿极化方向的倒极化率分量是连续的，然而垂直于极化方向的倒极化率分量不连续，这是一个非常有趣的现象。

Models of single-phase inverter are established, and the causes of waveform distortion are analyzed.

建立了单相逆变器的数学模型，分析了逆变电源输出电压畸变的原因。

This paper studies a single phase voltage SPWM inverter based on repetitive control, whose key point is achieving a good sinusoidal output wave. Firstly, this paper detailed discusses the inverter system"s working characters and mathematic model. Then repetitive control technique and the choice of its parameters, the whole system"s stability, the strategy of closed-loop control are discussed. Finally

本文首先阐述了逆变系统的工作原理，对单相逆变电源的建模进行了详细讨论；然后论述了重复控制技术理论的原理，重复控制系统参数的选择、整个系统的稳定性、闭环反馈控制的策略；最后给出了基于MATLAB的仿真结果和基于单片机C8051作控制系统的实验结果，并对实验过程中存在的问题进行了详细的讨论。

You are quite triumphant This very moment mood Real own because I very much treasureour meeting one another very very much, that has the certain fate, Ireally did not hope because of me the impulse idea, can cause oursentiment for a while to go bad Causes our friendship to change isnot good I really very much blame oneself, because own are the Chinese China'smatter manages again not not well also wants a type foreign countryold person to worry for me, I really very much do not have useful hereme only to be able with you to say again the sound sorry friend ofmine Hoped you can forgive my I since knew I have owed you to be very many always all do not have tobe able also to give you However this I have the difficulty to havein turn said with you, actually again I and you said previous two daysI had thought are very many, should I say with you, but when I makethe phone call for yours time I on regret But or said with you Againhere I hoped you do not blame me, I already very much to regret Triumphant I did not know I this action can let between us nearby thefriendship not be good Triumphant I knew the dissimilarity which weare the heart have cleverness but looked like you before to say,between us the communication really was very difficult to be verydifficult, but was in is difficult I also to hope which country nomatter you were at, perhaps worked I in there all to hope we couldhave the relation Between each other friendship is invariable, knewfinally is good..............

你很得意这一刻的心情真实的，因为我很treasureour会议的另一项极大，有一定的命运， ireally不希望因为我的冲动想法，可造成oursentiment了一会儿变坏，导致我们的友谊改变isnot好，我真的很责怪自己，因为自己是中国china'smatter管理又不是没有好，也想一类外商countryold人担心对我来说，我真的很没有有用hereme唯一能与你再次要说声对不起朋友ofmine希望你能原谅我，因为我知道我欠你太多，总是并非所有人都有创新型，也可以给你，但这次我有困难havein反过来说：与你，其实我和你说上两daysi还以为是很多，应该说，我与你，但当我出了电话，为你的时候我就后悔，但还是说你againhere希望你不怪我，我已经非常后悔胜利，我不知道我这一行动可以让我们之间附近thefriendship 没有好的胜利，我知道相异，我们正在进行的心脏有聪明的，但看上去像你以前说，我们之间的沟通真的是一件很困难的是verydifficult ，但在艰难的是，我也希望有哪个国家nomatter您的，或许工作，我在这里向所有希望我们couldhave的关系，彼此之间的友谊是不变的， knewfinally是好的。。。。。。。。。。。。。。

In the two phase zone between liquidus and solidus, as fraction solid and deformation rate increase, the deformation mechanism changes from LF and FLS to SS and PDS.

在液固两相区间，随着固相分数和变形速率的提高，触变压缩过程中合金主导变形机制将由液相阻尼流动和液相流动逐渐转变为颗粒塑性变形和颗粒滑动。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
