LABoratory

LABoratory,英语单词,名词,意为“实验室,研究室”。实验室(LABoratory/Lab [1] )即进行实验的场所。实验室是科学的摇篮,是科学研究的基地,科技发展的源泉,对科技发展起着非常重要的作用。
  • The paper describes the concept and realization of the DOOCS control software for FPGAbased TESLA c

    The paper describes the concept and realization of the DOOCS control software for FPGAbased TESLA cavity controller and simulator (SIMCON). It bases on universal software components, created for LABoratory purposes and used in MATLAB based control environment. These modules have been recently adapted to the DOOCS environment to ensure a unified software to hardware communication model. The presented solution can be also used as a general platform for control algorithms development. The proposed interfaces between MATLAB and DOOCS modules allow to check the developed algorithm in the operation environment before implementation in the FPGA. As the examples two systems have been presented.

  • MD5的全称是Message-digest Algorithm 5(信息-摘要算法)

    MD5的全称是Message-digest Algorithm 5(信息-摘要算法),用于确保信息传输完整一致。在90年代初由MIT LABoratory for Computer Science和RSA Data Security Inc,的Ronald L. Rivest开发出来,经MD2、MD3和MD4发展而来。它的作用是让大容量信息在用数字签名软件签署私人密钥前被"压缩"成一种保密的格式(就是把一个任意长度的字节串变换成一定长的大整数)。

  • RISK+COMMUNICATION

    The fi rst edition of this book came about because Regina Lundgren had always been fascinated with communication. She started writing novels in the third grade. When she was asked on her fi rst day at the University of Washington what she hoped to do with her degree in scientifi c and technical communication, she replied, “I want to write environ- mental impact statements.” When Patricia Clark hired her to work at the Pacifi c Northwest National LABoratory to do just that, she was overjoyed.

  • 用于10kVIGBT固体开关的脉冲变压器设计

    由于高重复频率固体开关在加速器、雷达发射机、高功率微波和污染控制等领域存在的潜在优势,美国、英国、日本和韩国等都对固体开关技术进行了大量研究,从而成为近年脉冲功率界研究的重点1。从固体元件电路结构上,固体开关可以分成两种类型:串联结构和累加器结构。采用串联结构的固体开关生产厂家中,比较著名的有LLNL(Lawrence Livermore National LABoratory)和DTI(Diverfisied Technology Inc.),采用累加器结构的厂家中,比较著名的是LLNIL.和美国的First Point Scientific Ine.B32A我们已经研制成功了采用光纤控制的10kV绝缘栅双极型晶体管(Isolated Gate Bipolar Transistor,IGBT)固体开关,尽管在该固体开关中采用的光纤收发器比较便宜,但光纤控制部分还是比较昂贵的。在一定的应用环境,如脉冲宽度为几微秒到十几微秒,可以采用脉冲变压器来控制IGBT。从文献[1]表明:只要脉冲同步和缓冲电路设计适当,即可确保固体开关中不会出现过压。尽管脉冲变压器隔离控制在同步精度和驱动波形一致性方面不如光纤控制,但还是可以用来控制IGBT固体开关。采用脉冲变压器控制IGBT的主要优点是价格便宜,但其存在的主要问题是输出脉冲宽度范围比较有限和绝缘性能如何保证的问题。在脉冲变压器控制的IGBT固体开关中,脉冲变压器设计非常重要,因此下面只讨论脉冲变压器的绝缘问题和IGBT固体开关的实验结果。
