When pumped with 800 nm laser irradiation, chromophores BPODPA, BBPOPA, and TBPOA showed strong two-photon excited blue green fluorescence at 502, 515, and 518 nm, respectively. These multibranched chromophores showed large TPA cross-section.

在800nm波长的激光激发下，化合物BPODPA、BBPOPA和TBPOA在二氯甲烷溶液中发出很强的蓝绿色双光子上转换荧光，荧光峰分别位于502、515和518nm。

The enhanced two-photon absorption found in these chromophores was attributed to the fact that the multibranched chromophores had both an extended π-conjugated system and an increased intramolecular cooperative effect compared to the one-branched chromophore.

这些多枝结构化合物的双光子吸收截面较大，双光子吸收增强来源于多枝分子中扩展的π共扼体系和重复单元的协同效应。

Secondly,two-photon entangled pair is produced in noncollinear direction.Wediscuss the influence of fourth-order interference with three different length crystalsand with different frequency distribution of interference filters.

其次，利用飞秒脉冲II型参量下转换在非共线方向产生偏振纠缠的双光子对，我们利用三块不同长度晶体分析晶体长度以及探测谱线宽度对纠缠四阶干涉的影响，实验选用长度分别为0.1mm、0.5mm和1.0mm的BBO晶体。

The cavity field spectrum of the nondegenerate two-photon Jayners-Cummings model with an additional Kerr medium is studied.

Oxygenic photosynthesis uses water as an electron donor which is oxidized into molecular oxygen by the absorption of a photon by the photosynthetic reaction center.

Oxygenic光合作用使用水作为被氧化入分子氧气由光子吸收由光合作用的反应中心的给电子体。

Methods and Results— Using a micro–single-photon emission computed tomography small-animal imaging system and a Food and Drug Administration–approved radiotracer ([indium 111] oxyquinoline, 111In-oxine), we demonstrate here that monocyte recruitment to atherosclerotic lesions can be visualized in a noninvasive, dynamic, and 3-dimensional fashion in live animals.

方法和结果——采用微单光子发射计算机断层摄影术的小动物成像系统和美国食品药品治理局认同的放射性示踪剂（111In-oxine），我们证实动物体内单核细胞向动脉粥样硬化损害处的聚集能够通过一种非侵入性，动态的，3维方式进行可视化观察。

方法和结果：我们通过Micro-SPECT小动物显像系统和FDA批准的示踪剂（铟111-羟化喹啉），证实单核细胞向AS病变处募集过程可以被非侵入性影像技术动态、三维模式观察到。

We studied the jets photoproduction and it's application in testing the perturbative QCD theory, as well as the relations of jets cross section to the parton distribution in photon and proton. The dependence of jets cross section on scales is also discussed both in LO and in NLO corrections.
