μmhos/cm is aligned with 0.03% sulfated ash.

2. A supplier with a history of acceptable microbiological viable count data may use

Direct Microscopic Examination (DME) for daily release of product. DME does not replace the quarterly microbiological testing for viable mesophilic total count and yeast and mold count designed to demonstrate conformance to the specification. 3.Business Unit can set a different range of pH as required by applicable regulations

and agreed with the supplier.

4.Business Unit may accept the shipment at the temperature slightly different from the

above temperature when the supplier can guarantee quality and integrity of the shipment, including the results of taste, odor and appearance are satisfactory.

5.The methods referenced in the specifications are either internal or industry-

recognized methods. If the Group/Business Unit agrees with the supplier to use a method different from that listed in the specification, the method must be validated

and available upon request. In any case where the results of an analysis are under

investigation, the method listed above must be used and The Coca-Cola Company method must be used as a preferred method.

GMO Status for shipment to the EU

?Apply this requirement only to ingredients destined to EU, to ensure compliance with GMO EU directives 1830/2003/EC and 1829/2003/EC.

?Supplier must provide batch-specific declaration of the GMO status for each batch and delivery. This can be included in the Certificate of Analysis or Compliance

(preferred method), or in a separate document stating the GMO status.

?Any ingredient declared by the supplier as containing GMO materials requires The Coca-Cola Company, Corporate-SRA and Group/Business Unit-SRA review

and approval.

NOTE: The supplier may provide the Buyer with an annual letter stating the

GMO status for the ingredient; however, this letter is not required by EU

regulations and is not a substitute for the batch-specific declaration.

Manufacturing Conditions

?HFSS 55 must be manufactured, packaged, stored and shipped under sanitary conditions appropriate to food products and in compliance with applicable food

hygiene, health and sanitary requirements and regulations. This includes current

Good Manufacturing Practices, and local, national and international transport laws and regulations in effect at and between the manufacturing and receiving locations.

o Sweetener Pesticide Monitoring Guideline includes a multiple-barrier process to ensure satisfactory implementation of the Sweetener Pesticide Program.

Biocides

?Any substance used for controlling microorganisms in the finished HFSS must be permitted for such use by applicable laws and regulations.

?Upon request by the Group/Business Unit, the supplier must be able to document the name of each such substance and the extent to which it was applied to the

process.

?There must be no remaining residue of any substance used to control microorganisms at the lower detectable limit capable of analyzing the targeted

substance in the finished HFSS at delivery to the operation.

Records

? A five (5) year retention period is required for GMO compliance records.

?Records of any pesticides or biocides used must be made available on request.

Examples of records include:

o The name of each pesticide or biocide used

o When and where each pesticide or biocide was used

o The dosage and how each pesticide or biocide was applied

?If the supplier performs pesticide analysis on raw materials or by-products, records of these analyses must also be made available on request.

Labeling and Packaging

?HFSS 55 must be labeled and delivered in containers approved for food use by applicable regulatory agencies. The containers must be equipped with nontoxic,

supplier-identifiable, tamper-evident seals approved by The Coca-Cola Company.

基于HFSS带通滤波器设计文献综述

2012 届本科毕业设计（论文）文献综述 题目基于HFSS的带通滤波器设计 学院物理与电子工程学院 年级08 专业电子信息工程 班级 2 学号160408220 姓名刘建 指导教师施阳职称

基于HFSS 带通滤波器设计文献综述 1引言 我们知道，当一定复杂程度的信号通过几乎任何电子系统时，它都需要经过某种滤波电路进行滤波。一般在一个实际应用的电子系统中，因输入信号往往因受干扰等原因而带有其它一些不需要的频率信号，就必须使用滤波电路将它衰减到足够小的程度。滤波电路是一种可通过或阻止某种频率信号的电路，其功能就是让指定频段的信号能顺利地通过，而对其它频段的信号起到衰减作用。它分为两种：无源和有源滤波电路。无源滤波电路是由无源器件(电阻、电容和电感)组成，性能较差有源滤波电路是由集成运算放大器和RC 等网络构成，具有几个主要优点：体积小，重量轻；电路的输入和输出之间具有良好的隔离；除了起滤波作用外，还可放大输入信号，且容易调节放大倍数等。BPF 主要用来截取突出有用频段的信号，削弱其余频段的信号或干扰和噪声，以提高信噪比。 2 设计原理 2.1 带通滤波器工作原理及HFSS 简介 带通滤波器中作原理 一个理想的滤波器应该有一个完全平坦的通带，例如在通带内没有增益或者衰减，并且在通带之外所有频率都被完全衰减掉，另外，通带外的转换在极小的频率范围完成。实际上，并不存在理想的带通滤波器。滤波器并不能够将期望频率范围外的所有频率完全衰减掉，尤其是在所要的通带外还有一个被衰减但是没有被隔离的范围。这通常称为滤波器的滚降现象，并且使用每十倍频的衰减幅度dB 来表示。通常，滤波器的设计尽量保证滚降范围越窄越好，这样滤波器的性能就与设计更加接近。然而，随着滚降范围越来越小，通带就变得不再平坦—开始出现“波纹”。这种现象在通带的边缘处尤其明显，这种效应称为吉布斯现象。在频带较低的剪切频率1f 和较高的剪切频率2f 之间是共振频率，这里滤波器的增益最大，滤波器的带宽就是2f 和1f 之间的差值。 HFSS 简介 HFSS 是ANSOF T 公司开发的一个基于物理原型的EDA 设计软件. 使用HFSS 建立结构模进行3D 全波场分析,可以计算.①基本电磁场数值解和开边界问题,近远场辐射问题; ②端口特征阻抗和传输常数; ③ S 参数和相应端口阻抗的归一化S 参数; ④结构的本征模或谐振解.依靠其对电磁场精确分析的性能,使用户能够方便快速地建立产品虚拟样机.

hfss详细的滤波器设计

在论坛逛了也有些日子了，发现有很多初学者其实是怀着兴奋的心情来论坛，希望可以在这里初窥滤波器的奥秘，希望有朝一日自己也可以成功的设计出一款性能不错的滤波器。下面介绍的虽然是普通的滤波器设计流程，但其具有很强的代表性，大多数耦合谐振器滤波器都应遵循下面的几个设计步骤，尤其是对于初学者，这可以帮助大家理解最最最最基本的概念。当然了，对于高手来说，其实可以省略很多中间过程。 声明：本文是基于Jia-Sheng Hong 的‘Microstrip Filters for RF Microwave Applications’中第八章、第九章所介绍内容。 1，首先，我们要对耦合矩阵有个感性的了解。大家在看论文时，其实可以看到都会给出一个对应的耦合系数矩阵。用来综合耦合系数的软件很多，大家可以花点时间稍微研究下就可以了。需要指出的是，曾经有同学问我，为什么我用软件综合出的耦合系数矩阵中的系数都那么大，很多在1左右，好像无 法实现啊！原因是：综合出的矩阵是归一化的耦合矩阵，你需要乘以你设计的百分比带宽才能得到你所想要的真实的耦合系数。例如书中的式子 2，拥有了耦合系数矩阵，就需要确定所采用的谐振器类型，整个滤波器的几何结构。此处采用一个四阶开口环交叉耦合滤波器来做为实例，下面的耦合系数矩阵是我从一篇文章copy过来的，只是作为一个辅助。（正、负仅仅是一个符号，一般来说，我们将正值视为磁耦合，负视为电耦合，反之亦然） 其对应的几何结构如下所示，其中1和4是开口相对，为什么呢，因为微带开路端电场比较强，这么放置1和4才能产生耦合系数矩阵中所需的电耦合。同样的原理，我们知道2和3之间产生的是磁耦合，至于1和2、3和4为什么这么放，它们之间是混合耦合，建议大家去看书，解释起来麻烦点。
