Through this experiment,it was measured that average diameter of the fundamental frequency light is 2.33 mm in the pattern of ordinary krypton pump,while in he pattern of the laster- diode bar pump the average diameter is only 1.25 mm,and the light field of the later also took on the standard Gaussian distribution,therefore formed the high-bright...

通过实验测量到普通氪灯泵浦方式中基频光的平均直径为2.33 mm，LD 阵列对称泵浦方式中基频光的平均直径仅为1.22 mm，并且呈现标准的高斯分布，形成了高亮度激光输出。实验研究了 Nd：YAG 调 Q 固体激光器的重复频率对 KTP 倍频晶体转换效率的影响。并且，在基频光平均功率11.2 w时，经 KTP 晶体倍频产生5.11W 的532 nm 绿光输出，光-光转换效率达到45.6%。

After comparing with the thermal conductivity under two different conditions, the thermal conductivity with vacancy is lower than that with Kr, which accounts for phonon scattering on impurities due to lattice strain is stronger than that due to differences in mass between the defect and the surrounding matrix.

模拟结果显示，温度在20~80K之间，考虑热膨胀时的导热系数比晶格常数固定时的值要低，但随温度变化的关系更加接近实验值时的情况；比较固体氩中不同掺杂时导热系数大小，发现同样掺杂浓度条件下，掺空穴时材料导热系数比掺氪时低，说明掺杂时由于晶格不匹配引起的声子散射比不同质量引起的散射更重要。

Begin from acute edema, hyperplasy and reparative process accompanied by acute inflammation , subsiding edema, scarification and mussy pigment in turn were found in the photocoagulative spots ; CNV begins to emerge 1w after photocoagulation, and continuely develop during 1w～4w, the growth of CNV displayed the most productive during the time of 1w to 2w, while there is no difference between 3w and 4w, From 4w to 12w, fibrous tissue was mainly seen to increase within CNV membrane.

结果1。氪激光光凝后激光斑从急性水肿开始，依次经历急性炎症、水肿消退、斑痕化和色素化的增生修复过程；1w开始形成CNV，1w～4w随时间迁延CNV持续发展，以1w～2w CNV生长最为旺盛，3w、4w之间差异不明显，4w之后至12w主要表现CNV膜内纤维组织增加。2。

The data the researchers have collected on the krypton and xenon isotope ratios are "superb," says physicist Bob Pepin of the University of Minnesota, Twin Cities."They're of a quality not seen before."

"研究人员搜集的有关氪和氙同位素比值的数据很可靠，"明尼苏达大学双城分校的物理学家鲍勃·佩平说，"这些数据的质量之高是前所未有的。"

Originally Superman's pet on the planet Krypton17, Krypto the Superdog was sent up in a test ship by Superman's father and now lives on earth with a boy named Kevin Whitney.

克利普托原本是超人在氪星上的宠物狗，超人父亲用实验飞船将它送到了地球，现在它和一个名叫凯文·惠特尼的男孩住在一起。

Using a nonperturbative scattering theory developed by Guo,Aberg and Crasemann the angular distributions of electrons in above threshold ionization of Krypton atoms irridated by a bichromatic phase-controlled laser field of linear polarizations is studied. The bichromatic phase-controlled laser field is composed of a sequence of identical one-cycle laser pulses.
