AptanaStudio3 安装在win7 64bit时遇到的问题

最近在研究前端语言，想起可以使用AptanaStudio这个前端利器，没想到安装时却遇到波折。

先从网上下载了Aptana版本3.6.0 64bit

问题1 安装进度缓慢，第一次安装时，显示downloadfiles类似语句，进度条一直停滞，并在约10分钟左右，连续弹出两个MessageBox，分别是关于git和node.js的，我估计是需要这两个工具，但国外服务器延迟大，导致下载失败，遂手动安装，依次安装后，问题解决。问题2 安装好以后打不开。

双击图标，竟然打不开，郁闷。提示 failed to load the jni shared library jre/....

网上搜索类似关键字，大量都是关于eclipse的，大致都认为与没有正确安装和配置java 64位下环境变量有关。Aptana和eclipse使用的框架时一致的，但是问题却不在这里，我本机已经有了java6和java7 环境，并且eclipse运行也是正常的。百度无果，只能上Aptana 官方文档一探究竟。

据文档上描述，原来Aptana只支持32bit的jre环境，如果在本机无法搜到jre的话，就直接下载一个java7到Aptana的安装目录下。看来是Aptana的安装包制作有bug，好吧，直接从我虚拟机里提取了一个32bit的jre，放到Aptana目录下，顺利解决。

光纤通信RF方面的中英文翻译

RF和微波光纤设计指引 Name: Class: Student NO.:

RF and Microwave Fiber-Optic Design Guide Agere Systems Inc., through its predecessors, began developing and producing lasers and detectors for linear fiber-optic links nearly two decades ago. Over time, these optoelectronic components have been continually refined for integration into a variety of systems that require high fidelity, high frequency, or long-distance transportation of analog and digital signals. As a result of this widespread use and development, by the late 1980s, these link products were routinely being treated as standard RF and microwave components in many different applications. There are several notable advantages of fiber optics that have led to its increasing use. The most immediate benefit of fiber optics is its low loss. With less than 0.4 dB/km of optical attenuation, fiber-optic links send signals tens of kilometers and still maintain nearly the original quality of the input. The low fiber loss is also independent of frequency for most practical systems. With laser and detector speeds up to 18 GHz, links can send high-frequency signals in their original form without the need to downconvert or digitize them for the transmission portion of a system. As a result, signal conversion equipment can be placed in convenient locations or even eliminated altogether, which often leads to significant cost and maintenance savings. Savings are also realized due to the mechanical flexibility and lightweight fiber-optic cable, approximately 1/25 the weight of waveguide and 1/10 that of coax. Many transmission lines can be fed through small conduits, allowing for high signal rates without investing in expensive architectural supports. The placement of fiber cable is further simplified by the natural immunity of optical fiber to electromagnetic interference (EMI). Not only can large numbers of fibers be tightly bundled with power cables, they also provide a uniquely secure and electrically isolated transmission path. The general advantages of fiber-optics first led to their widespread use in long-haul digital telecommunications. In the most basic form of fiber-optic communications, light from a semiconductor laser or LED is switched on and off to send digitally coded information through a fiber to a photodiode receiver. By comparison, in linear fiber-optic systems developed by Lucent, the light sent through the fiber has an intensity directly related to the input electrical current. While this places extra requirements on the quality of the lasers and photodiodes, it has been essential in many applications to transmit arbitrary RF and microwave signals. As a result, tens of thousands of Agere Systems’ transmitters are currently in use. The information offered here examines the basic link components, provides an overview of design calculations related to gain, bandwidth, noise, and dynamic range

光纤通信系统Optical_Fiber_Communications_英文资料及中文翻译

光纤通信系统 Optical Fiber Communications 英文资料及中文翻译 Communication may be broadly defined as the transfer of information from one point to another .When the information is to be conveyed over any distance a communication system is usually required .Within a communication system the information transfer is frequently achieved by superimposing or modulating the information on to an electromagnetic wave which acts as a carrier for the information signal .This modulated carrier is then transmitted to the required destination where it is received and the original information signal is obtained by demodulation .Sophisticated techniques have been developed for this process by using electromagnetic carrier waves operating at radio requites as well as microwave and millimeter wave frequencies. The carrier maybe modulated by using either optical an analog digital information signal.. Analog modulation involves the variation of the light emitted from the optical source in a continuous manner. With digital modulation, however, discrete changes in the length intensity are obtained (i.e. on-off pulses). Although often simpler to implement, analog modulation with an optical fiber communication system is less efficient, requiring a far higher signal to noise ratio at the receiver than digital modulation. Also, the linearity needed for analog modulation is mot always provided by semiconductor optical source, especially at high modulation frequencies .For these reasons ,analog optical fiber communications link are generally limited to shorter distances and lower bandwidths than digital links . Initially, the input digital signal from the information source is suitably encoded for optical transmission .The laser drive circuit directly modulates the intensity of the semiconductor last with the encoded digital signal. Hence a digital optical signal is launched into the optical fiber cable .The avalanche photodiode detector (APD) is followed by a front-end amplifier and equalizer or filter to provide gain as well as linear signal processing and noise bandwidth reduction. Finally ,the signal obtained is

CHAPTER 8 MAKING CAPITAL INVESTMENT DECISIONS Answers to Concepts Review and Critical Thinking Questions 1. In this context, an opportunity cost refers to the value of an asset or other input that will be used in a project. The relevant cost is what the asset or input is actually worth today, not, for example, what it cost to acquire. 2. a.Yes, the reduction in the sales of the company’s other products, referred to as erosion, and should be treated as an incremental cash flow. These lost sales are included because they are a cost (a revenue reduction) that the firm must bear if it chooses to produce the new product. b. Yes, expenditures on plant and equipment should be treated as incremental cash flows. These are costs of the new product line. However, if these expenditures have already occurred, they are sunk costs and are not included as incremental cash flows. c. No, the research and development costs should not be treated as incremental cash flows. The costs of research and development undertaken on the product during the past 3 years are sunk costs and should not be included in the evaluation of the project. Decisions made and costs incurred in the past cannot be changed. They should not affect the decision to accept or reject the project. d. Yes, the annual depreciation expense should be treated as an incremental cash flow. Depreciation expense must be taken into account when calculating the cash flows related to a given project. While depreciation is not a cash expense that directly affects c ash flow, it decreases a firm’s net

4、选择自己当前的系统版本 运行nt6_hdd，会出现下面的窗口，如果您现在的系统是XP可以选择1，如果是vista或者win7选择2，选择后按回车开始安装，1秒钟左右结束，之后就是重启系统了。 5、开始安装Win 7系统 在启动过程中会出现如下界面，这时选择新出来的nt6 hdd Installer mode 1选项，下面就开始安装了，按照安装步骤一步一步就行了，其中需要设置的地方，自己看着办。

重装系统Win7步骤和详细教程(2014版_附系统映像)

本贴针对那些不会重装系统的用户，虽然重装系统很简单，但是还是有一些小白是不会重装的，本教程现在就详细的讲一下重装系统的具体步骤，本帖以重装Windows7系统为例，讲述一下重装系统的详细步骤。 首先，重装系统之前需要将电脑中的重要资料备份和转移，这是非常重要的，备份完成后，下面我们开始重装系统 第一步 下载Onekey ghost下载地址 https://www.wendangku.net/doc/c61153917.html,/soft/detail/23409.html 下载Windows7映像下载地址 https://www.wendangku.net/doc/c61153917.html,/s/15wrIA 注意：以上两个都不要保存在C盘 第二步 打开Onekey ghost，选择还原分区，在GHO WIM ISO映像路径选择刚下载的Windows7.GHO。如下图

接下来， 在底下选择还原到C盘（点击C盘，然后那C盘一条会变蓝）。如下图，然后点击确定。 点击确定后，会弹出一个提示框（如下图），询问是否重启，点击是。接下来计算机会重启。 计算机重启后，会出现下图的情况，什么都不需要做，等进度条走完即可

进度条走完后，计算机会再次重启，Windows会自动安装，什么都不需要做，等计算机进入桌面后，重装系统就算完成了。 重装完成后需要做的 1.检查系统是否经过正版激活 方法：控制面板--系统，拉到最下面看看是否激活（如果显示状态不可用，需要等一会） 如果未激活，下载小马激活工具激活https://www.wendangku.net/doc/c61153917.html,/s/1gdBUUGF 2.根据自己的使用习惯调整系统设置 3.将备份的数据导入回去 4.下载安全软件，个人推荐卡巴斯基，AVG，nod32，诺顿，小红伞，这些杀软都进入国内了，杀毒能力明显是比国产强的，这几个有的有免费版，收费的其实在淘宝几块钱就能买到一年的激活码，国产的诸如电脑管家之类的可以当做系统辅助类软件用，因为国外的杀软基本都不带清理垃圾，系统优化这之类的功能，可以两者结合使用。 5.根据自己使用习惯下载软件等等
