英文: Abstract: A laser damage facilities,which has mm size spot and operates in TEM00 mode, were achieved.In order to know the reasons of laser damage,the laser energy density was controlled near the damage threshold of the oxide thin films.According to the ex

中文: 文摘:采用毫米量级大光斑的近单模的激光器,控制入射薄膜表面的激光能量,获得了几种常见单层膜和增透膜的损伤形貌,实验结果表明,薄膜的损伤可区分为熔化型和应力型两种,薄膜表面等离子体对损伤斑点的扩大有重要作用。       更详细...
英文: Along with the rapid development of portable electronic devices and MEMS products, the requirement of increasing the energy density of power supply unit is urgent.

中文: 摘要随著便携式电子产品和微机电系统(MEMS)的迅速发展,对电源能量密度的要求不断提高。       更详细...
英文: Although it is possible that new attempts to estimate the vacuum energy density may yield just the right amount to explain cosmic acceleration, many theorists believe that a correct calculation, incorporating a new symmetry principle, will lead to the con

中文: 虽然新的估算有可能得到能解释加速膨胀现象的真空能量密度,但多数科学家相信,经过正确的计算再配上新的对称性原理,得到的量子真空能量将会是零(量子真空亦是空)。       更详细...
英文: Because the way the dark energy density varies is dependent on the theoretical model, each theory predicts a different time for the transition point when the expansion of the universe switched from slowdown to speedup.

中文: 因为暗能量密度随时间的改变方式和理论模型有关,因此,在每个理论中,宇宙由减速过渡到加速膨胀的时间点亦不尽相同。       更详细...
英文: But when theorists try to compute the energy density associated with the quantum vacuum, they come up with values that are at least 55 orders of magnitude too large.

中文: 然而,当理论学家尝试计算这个量子真空的能量密度时,他们得到的结果比目前的观测值至少大55个数量级。       更详细...
