C. There will be no more strict vacuum requirements. ? 18.She tried to look healthy __________ her husband. ? Now, researchers of the Max Planck Institute for Quantum Optics and the University of Munich have dramatically simplified atom laser construction by using a thumbnail-sized microchip to achieve Bose-Einstein condensation. In their experiments，the cloud of condensed atoms hovers just above the micron-sized gold wires which are inscribed on the chip. The microchip not only replaces the coils and cuts the power consumption to a small fraction of what it used to be. In addition，it drastically shortens the time required to produce the condensate，from about a minute to a few seconds. This in turn relaxes the stringent vacuum requirements of the older experiments. ? B. How bacteria are resistant to antimicrobial drugs. C. By follow-up visits. ? A few years ago，the first atom lasers were built，devices that produce a beam of atoms with many of the properties of a laser beam. Now physicists at the Max Planck Institute for Quantum Optics and the Ludwig-Maximilians-Universitaet in Munich have demonstrated that atom lasers can be integrated on a microchip. This result dramatically simplifies the production of laser-like matter waves，and call be compared to the step from single transistors to integrated microelectronics. The new devices are expected to become key components in future technologies ranging from ultraprecise measurements to quantum information processing. ? III.
