查询词典 second rate

First, the S-CDMA-HFC system with integrated traffic is introduced and the method of traffic integration is given. Second, the upstream channel capacity of the S-CDMA-HFC system with integrated traffic that has the same rate is analyzed. The chronoff limit and Gaussian approximate equation of the upstream channel cutoff probability are derived. Third, the impact of the selection of the line transmission rate on the upstream channel capacity of the S-CDMA-HFC system with integrated traffic is discussed in detail. The cutoff probability and throughout equations of the upstream channel with different integrated traffic are derived. Fourth, the impact of the power control error on the capacity is discussed. Results show that the power control error will degrade the upstream channel capacity and have different influence on the different traffic. Finally, the capacity requirement of the initialization process is raised. Analytical results show that the initialization process will impact on the capacity slightly.

首先，简单介绍了综合业务S-CDMA-HFC系统，给出了业务综合的方法；然后，分析了具有相同码率的综合业务条件下的S-CDMA-HFC系统上行信道容量，导出上行信道中断概率的切尔诺夫上限和高斯近似公式；然后，详细讨论了基本传输速率的选择对综合业务S-CDMA-HFC系统上行信道容量的影响，导出了不同业务综合条件下上行信道的中断概率和吞吐量公式；然后，讨论了功率控制误差对综合业务S-CDMA-HFC系统上行信道容量的影响，结果表明功率控制误差会使上行信道容量下降，且对不同业务的影响程度是不同的；最后给出了初始接入的容量要求，分析结果表明初始接入将对综合业务S-CDMA-HFC系统上行容量带来影响，但不明显。

Among them, the long term interest rate is chosen as the intermediary target by Keynes school, and money supply chosen by Monetarism, the interest rate chosen by horizontalism with consideration that the interest rate elasticity of the monetary demand is very high, and William Poole thinks that the choice of intermediary s targets must depend on two factors: First is which is more unstable between the actual economy and money. Second is the slope of IS and LM curve.

现将每章的主要内容分述如下：论文第一章对货币政策中介目标国内外的理论作了一个研究综述，提出理论界在选择货币政策中介目标方面的不同观点，其中国外有：凯恩斯主义认为应将长期利率作为中介目标，货币学派认为应将货币供应量作为货币政策的中介目标，普尔认为中介目标的选择必须取决于两个因素：一是实际领域和货币领域哪个部门更不稳定，二是IS和LM曲线的斜率；水平主义理论主张，在货币需求的利率弹性很高的前提下，利率也就成为货币政策的中介目标。

To put up founding and test experiments in these two ways separately, the first model use fixed training data to train the network and it constringed at the ninety circles, it's test identifying rate is eighty eight percent;the second model use the same fixed training data to train the network and it constringed at the sixty circles, it's test identifying rate is ninety nine percento Thus shows that the model with the switched character data is more better in identifying rate and it' s training time is shorter than the model used the character data directly,, Use BP Neural Network to forecast the Medicine Production quality is a better method..

As the concentration of FeO increasing, the rate of decarburizing and reaction-dissolving of refractory rises sharply. Meanwhile gas production rate of reduction reaction is increased and motion and foaming of molten slag are also speeded up. The corrosion feature of refractory containing graphite carbon is that the most severity area is slag level (interface of slag-gas phas -refractory) and slag-metal interface comes second, and the lowest corrosion rate is the area of iron-bath.

熔体的组成、温度及熔体与耐火材料间的相对运动对耐火材料的侵蚀产生着很大影响，而熔渣中FeO浓度是最主要的因素，FeO浓度提高，使耐火材料脱碳和反应熔蚀速度呈直线上升，熔体中还原产生气体量增加，熔体涨泡及运动速度提高，这些作用都加快了熔体对耐火材料的侵蚀。

The ethylene release rate was measured in shoot tip of different sex ramie in different time, the budof same node in female and hermaphrodite ramie in second crops and different sex singleinflorescence in hermaphrodite ramie. The result indicated there was closed relationship betweensexual different ramie and ethylene release rate. The female ramie could be induced by highethylene release rate. the ethylene content in ramie plant with female flower is higher than ramieplant with androgynary in stem apex, leaf and flower.

Flat-nosed people are "hard life even buy houses", they did not know what is "real estate bubble"; experts and scholars to understand the bubble, according to China's housing prices and people's income ratio is much higher than international standards, there are is the vacancy rate in international comparison; but officials know how to "bubble" What does it mean, it never recognized the bubble, one that the Chinese have different national conditions, strokes and win one hundred strokes, is the so-called "the nation is a basket, what can be fitted inside" and second that different statistical data, you have your vacancy rate, and I have mine vacancy rate, the three said that even if there is also a partial bubble bubble, should not in addition to all; the most optimistic real estate developers, think China's real estate is in a the rapid development stage, there is no bubble in the shadow, the most credible, because recognition of the bubble, not only means that the property market even if it does not collapse, will be handover to the purchaser rational, but also may lead to credit crunch, such drastic things themselves No one dry, unless he is stupid.

平头的人&硬生活甚至买房子&，他们不知道什么是&房地产泡沫&；专家和学者了解泡沫，根据中国的住房价格和居民收入的比例远远高于国际标准，有是的是空置率国际比较；但官员知道如何&泡沫&是什么意思，它从来不承认泡沫，一个是中国国情不同，中风和赢得100杆，是所谓的&国家是一个篮子里，有什么可安装在&第二，不同的统计数据，你有你的空置率，和我有我的空缺率，三说，即使有也是局部泡沫泡沫，不应除了所有；最乐观的房地产开发商，认为中国的房地产正处于快速发展阶段，没有泡沫的阴影中，最可信的，因为承认了泡沫，不仅意味着楼市即使不垮，将移交给买受人合理，而且还可能导致信贷紧缩，如此激烈的事情本身，没有人干的，除非他是愚蠢的。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.
