E. , the fundamental cause of nonlinear coupled oscillation is the results of the interaction between the several nonlinear factors existing inside the motor, as well ws the mechanical drive, and the converter control system with discrete-sample and modulation.

本文依据理论分析、实验及现场测试研究，详细地分析了电力传动系统中存在的非线性耦合振荡现象，基本弄清了此类非线性耦合振荡的机理，即：电机内部非线性及机械拖动部分存在的多种非线性因素与具有离散采样和调制非线性特性的变流器控制系统之间的相互作用是造成系统非线性耦合振荡的根本原因。

If, on the other hand, the court finds that the document is a complete record of the contract, then it will reject the evidence of additional terms.

因为这个原因，申请人指出如果已有一份表面上完整的书面协议存在，某一方要能证明，在衡量相对的可能性下，另有一些协议条款存在是相当困难的事。

The inconsistencies of dimensional reduction and naive dimensional regularization in dealing withChern-Simons-matter theory are analyzed.The consistent dimensional regularization combiningwith higher covariant derivative regularization is adopted to consider Chern-Simons field theorycoupled to complex scalar and spinor field.All the local parts of one-loop two-point functionsand three-point functions are computed.Slavnov-Taylor identity is combined with these explicitcalculation results to give the one-loop local effective action.The finite gauge invariant quantumcorrection is shown and finite wave function renormalization constant for each field is defined.Thelocal part of one-loop three gauge field vertex is especially evaluated and it is verified that thereexists a renormalization choice compatible with BRST symmetry.

然后计算了所有的两点函数和三点函数单圈修正的定域部分，利用S-T恒等式给出了单圈定域有效作用量，定义了场的重正化常数，发现物质场和规范场都存在有限的规范不变的量子修正，并讨论了这些有限的规范不变的量子修正的物理意义，进而通过考察单圈三规范场顶角，表明存在与BRST对称性相容的重正化选择。5、在背景场方法的框架下，选择高阶协变导数正规化与维数正规化的杂化正规化方案计算了背景场两点函数的两圈量子修正，结果表明，标志紫外发散的极点项恰好抵消；进一步利用背景场方法中明显的规范对称性，证明背景场三点函数的两圈图贡献也是有限的。

Meanwhile, there exists critical level on which the exchange modes can be transformed to each other.

众多浙商的存在，会改善社会福利，表明市场内部本身就存在着可降低交易成本的机制。

In the Atalantic Croker and Kell Bass, two different ARs were reported which dispaying markly different steroid binding specificities. This is the first time people make sure that there are different AR isoforms with different affinity for T and DHT in a single body.

Wilson等人在人会阴皮肤的成纤维母细胞中发现存在两种不同的AR蛋白，命名为AR-A、AR-B；在对结肠癌的研究中，人们也已证实在结肠癌中存在两种不同的AR亚型表达，而且亚型表达的变化可能是结肠的发病因素之一。

And the cross correlation function is approximately zero, which makes them suppress the disturbances due to the other users. After describing some basic knowledge of chaotic theory in chapter 2, we interview and classify the applications of chaos in communications including chaos secure communication, chaotic spreading codes for multi-user access in spreading spectrum system and chaotic modulation and demodulation in chapter 3. FM-DCSK system with non-coherent demodulation offers the best performance in chaotic modulation schemes.

在混沌调制方案中， FM-DCSK调制是一种极具竞争力的混沌调制方式，它克服了CSK、COOK、DCSK解调中存在的估计问题的缺点，在无线信道的传输过程中，可以很好的抑制噪声干扰与多径衰落，并且能获得非常优越的解调性能，加上混沌信号本身优越的保密性能，该调制方式在未来的无线通信领域存在着巨大的潜在优势。

What's more the relations between different asset are classified to three groups which are the fundamental-derivative relation、the cross sectional relation and the comprehensive relation, on basis of which the asset pricing anomalies are classified individually to different groups.(2)The price model of the capital asset is constructed trailing the path of the asset value's incrementing and transferring. And then a three–factor model is established which can be utilized by the empirical researches. Concretely, under the capital chain, we conclude the relation between the stocks and the corporate assets is a fundamental-derivative one and the research object is the capital asset under the capital chain.

具体而言，本文在资产链的角度下分析股票和公司资产之间的"基础—衍生"关系，明确了本文的研究对象为资产链下的资本资产；建立了公司资产的价值，将公司资产和其基础资产公司的财产联系了起来，构造了资产链上第一个节点——公司资产的价值；将公司资产和资本资产进行了关联，在考虑公司资产变为资本资产的流动性增值后，建立了资本资产的价格模型；在前文资本资产价格模型的基础上进行了收益分解，基于此引入了具有长中短不同决策周期的三类投资者，在存在无风险资产和不存在无风险资产两种情况下分别建立了可用于实证的三因素模型。

Fertilization antigen 1 (FA-1) is an evolutionarily conserved antigen present in sperm of various mammalian species including mouse, rabbit, bull, rhesus monkey and human. It seems to have similar function and, shown to have cross-reaction among these species.
