Design and Implementation of Electronic process Panel in Manufacturing EnterprisesPrefaceIn the traditional production line process, the process is designed by means of equipment tools and posted to the specific Assembly positions after the specific review process. In this way, it is competent to assemble a single and slightly changed assembly line. However, in some cases. We have to face the following prob

The training and 2015 National Electronic Design competition is over.Many things were learned during the training period.Just started to use 2sc3355 to do 1.4GHz RF amplifier, using Microstrip line to do transmission line, on the Vector Network Analyzer to observe the parameters such as S11,S12,S21,S22. The amplifier effect is not very good. This and the circuit layout and general capacitance inductance in

After reading this article today, the students can do a little exercise, according to the article, the excellent set as an electric business site, the article as a commodity, to analyze which article is hot, what outstanding methods, the article contains what guide the user details and so on, that learning is used, not easy to forget, analysis well, I give you a little praise, Manual sort of. @AnyForWeb_UDC: The commodity list page in e-commerce is also referred to as the Product aggregation pa

A B/s platform for presenting enterprise newspapers and periodicals needs to be created in the recent project to record its own design ideas. First, I thought of Baidu Library. I made a similar demonstration of the enterprise's newspapers and periodicals and used flexpaper and ipv2swf for development. The final result was good, however, it is not suitable for newspapers and periodicals. Therefore, I visited the Internet and found that the multimedia

Swimming in the major electrical network of your website, in the online shopping I do not know if you have noticed a little different? Open the specific product content, visual style, memories of those we are familiar with the product page ... Of course, here is not to play people to pick up the game, need to look at the fine branches of the small. We can experience it from the details of the interface, and we can even squint to find something. Kiss, did you ever think of anything different?

classification of view will provide users with great convenience, of course, this also applies to the purchase factor more complex products, Users need to refer to more comprehensive advice when buying, such as laptops. From the following list of several sites, some of the site to do the evaluation of goods is very simple, such as wheat bag, but also some sites to do the commodity evaluation is very complex, such as jingdong, simple or complex no absolute good difference, mainly to refer to th

fall on the midpoint, this is the factor of luck, and we have nothing to do.When the test, we still have to be good, but the landing is not the first time so accurate, so, about the drop in the performance of a grade, but for the award we are still very confident. Here we have to say, we can see from the topic, the basic part is very simple, is basically the plane flew over a rope, about the landing and stability can not much requirements, many groups of students can do, the difficulty is hover
