The above title is not happenstance and was arrived at afterconsiderable deliberation. As a linear IC manufacturer, it isour goal to encourage users to design and build switchingregulators. A problem is that while everyone agrees thatworking switching regulators are a good thing, everyonealso agrees that they are difficult to get working. Switchingregulators, with their high efficiency and small size, areincreasingly desirable as overall package sizes shrink.Unfortunately, switching regulators are also one of themost difficult linear circuits to design. Mysterious modes,sudden, seemingly inexplicable failures, peculiar regulationcharacteristics and just plain explosions are commonoccurrences. Diodes conduct the wrong way. things gethot that shouldn’t. Capacitors act like resistors, fusesdon’t blow and transistors do. The output is at ground, andthe ground terminal shows volts of noise.
JPG Graph API
Win 32 JPG API is a 32bit JPEG api dll. You can call it to
show a JPG file in your program by only one sentence.
The only thing that you have to know is how to load a dll
libary and how to call ist functions. A example of Visual
FoxPro is supplied in package.
ASP開發(fā)指南,里面的西很不錯(cuò)的喲.This book is for anyone who wants to learn about using .NET for web interface design. Beginner or
hobbyist .NET developers can certainly get a good foundation of .NET web interface design by going
through this book from cover to cover. However, more seasoned .NET professionals, especially if they
tend to steer away from the GUI of their projects, can also pick up a thing or two by focusing on certain
chapters that appeal to them. This book is meant to take a reader from the beginning of a project to the
completion of the interface design. Along the way, concepts are illustrated to show how the different
pieces play together. So, anyone who really wants to understand the concepts presented in this book will
be able to do so by reading the entire thing. However, this book should also serve as a good reference
after you have read it or, in some cases, in place of reading it.
This package provides a complete http client library. It currently implements most of the relevant parts of the HTTP/1.0 and HTTP/1.1 protocols, including the request methods HEAD, GET, POST and PUT, and automatic handling of authorization, redirection requests, and cookies. Furthermore the included Codecs class contains coders and decoders for the base64, quoted-printable, URL-encoding, chunked and the multipart/form-data encodings. The whole thing is free, and licenced under the GNU Lesser General Public License (LGPL) (note that this is not the same as the GPL).
Recognizing its importance is only the fist step to advocate invetion or innovation， and some effective measures should be taken for it. For one thing， our authority should continue to enlarge the recruit of graduate. For another， the conditions of scientists and skilled workers should be further improved. Only in this way， can “the soul of our nation” be fully embodied and our nation have a brighter future.
