查询词典 first cost

SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

研究了软件无线电中的采样率转换技术，给出两种改进的CIC滤波器结构；(1)基于多相结构和部分尖锐化的CIC抽取滤波器，该结构适用于通带衰落要求不是很高，混迭抑制和滤波速度的要求相对较高的场合(2)一种改进CIC-Rotated Sinc抽取滤波器，该结构在获得好的通阻带特性的前提下，一方面降低了整个CIC滤波器结构的工作速率，另一方面尽可能地降低硬件实现的复杂度。

However, it became technically possible doing, it executes, first, enormous cost is required. Non- it dies in 2050 and to be accustomed,", it is not affluent if, sufficiently being just the affluent person, it must wait from 2075 to 2080,", that it has done.

但是， 它成为了技术上可能做，它执行，第一，极大的费用必需。2050 年它非死并且习惯，"，它不是富有的如果，充足地是正义的富有人，它必须等待从2075 年到2080 年，"，它做了。

The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.

通过极小化输出误差目标函数获得了系统参数估计；提出了正交梯度搜索方法用于解决系统参数的非唯一性问题，正交梯度搜索的本质是在输入-输出等价类相切平面的正交垂空间更新系统参数；给出了用 L-M 算法进行参数优化的充分条件；提出的系统参数递阶优化辨识方法包括两步：首先用给出的自适应 L-M 算子正交梯度方法确定参数优化方向；其次由一维搜索方法计算最佳步长。

First of all, shipping prices, most of China's steel demand to adopt a charter, signed a long single lock little cost, often outside the mine during the negotiations period to buy a large number of vessels, raise the sea-freight, driving up spot prices of iron ore; The second is to control the supply of cash, take advantage of China's steel market season, creating panic in short supply, is expected to raise prices; third, to promote intra-industry mergers and acquisitions, raise the ore concentration, grasp the initiative in the negotiations; Fourth, the use of exchange rate fluctuations The key point to find the best object of negotiations.

首先是海运价格，中国钢厂大部分采用即期租船，很少签长单锁定成本，外矿往往会在谈判期间买入大量期船，抬高海运费，从而抬高铁矿石现货价格；其次是控制现货供应量，利用中国钢材市场旺季来临，制造供应短缺恐慌，提高涨价预期；第三，推动行业内部并购，提高矿石集中度，掌握谈判主动权；第四，利用汇率变动的关键点，寻找谈判最佳对象。

In information processing, especially realtime video image processing usually have to deal with video images, which must first be designed largecapacity memory, synchronous dynamic random access memory SDRAM Although there are low cost, large capacity, etc., but SDRAM control structure of the complex, commonly used method is to design generic SDRAM controller, which makes a lot of people had to abandon the use of SDRAM and the use of expensive SRAM.

在信息处理中，特别是实时视频图像处理中，通常都要对实现视频图像进行处理，而这首先必须设计大容量的存储器，同步动态随机存储器SDRAM虽然有价格低廉、容量大等优点，但因SDRAM的控制结构复杂，常用的方法是设计SDRAM通用控制器，这使得很多人不得不放弃使用SDRAM而使用价格昂贵的SRAM。
