簇

Leaves simple, alternate, sometimes fascicled on short branchlets, conduplicate when young; petiole usually with 2 nectaries or sometimes nectaries at base of leaf blade margin; leaf blade margin often serrate.

Having densely tufted white cottony or downlike glumes.

具有浓密的簇状白色棉状绒毛或象绒毛的颖。

"For now, the best advice is to use su cree and rea ly them often — the Skin Cancer Foundation recommends every two hours, and e ecially after sweating or swimming, which can wash away su creen — to reduce the amount of UV radiation from getting through to filters that have penetrated the skin," said Christopher Bardeen, an a istant profe or of chemistry at UCR.

&目前，最好的建议是使用并经常反复涂抹防晒产品－皮肤癌基金会建议每两小时搽一回，尤其是在出汗或游泳之后，那样会使防晒霜流失－以便减少渗入到皮下的防晒成分所吸收的紫外线辐射量。&加州大学河滨分校助理化学教授克里斯托福。巴丁说，&这样反过来就能减少活性氧簇ROS的生成。&

Leaves evergreen, deciduous or semideciduous, alternate, sometimes clustered at stem apex; margin entire, very rarely crenulate, abaxial indumentum sometimes with a pellicle (a thin skinlike layer on the surface).

灌木或乔木陆生的或附生，常绿的叶，落叶或半落叶，互生，有时在茎先端的簇生；边缘全缘，极少具细圆齿，背面毛被有时具一表膜。

Lobular clusters of glands with cribriform architecture.

前列腺腺体的小叶簇伴有筛状结构。

The selective hydrogenation of crotonaldehyde to crotyl alchol was carried out over finely dispersed polyvinylpyrrolidone-stabilized ruthenium clusters.

以聚乙烯吡啶烷酮稳定的钌纳米金属簇为催化剂，进行了巴豆醛的选择性催化氢化。

Dark blue sprays of cyanotrichite.

The dispersion of particles are also related to the interactionbetween nanosilver and polymer. Nanosilver dispersed well in PS, while form larger branchedclusters in PMMA, and polymers could prevent nanoparticles from aggregation. The interaction between nanosilver and polymers depends on the properties of polymers and treatment. XPS results indicated that no obvious interaction between nanosilver and PS was foundbefore and after heat treatment; for AS matrix, there exists a interaction between nanosilver and AN,moreover AN on the nanosilver surface could cyclize and lose N after heat treatment at 150℃ for1h; for PMMA matrix, there exists a interaction between nanosilver and O atoms, heat treatment at150℃ for 1h could lead to the reaction between Ag, S and O in the interlayer of composite andchange the interface interaction.

纳米银粒子的加入改变了聚合物体系对激光能量的吸收和转换方式，导致其激光离解方式的变化，通常此种粒子会促进聚合物的炭化，且在界面可能有诱导石墨化的作用；而银粒子自身的离解及其对基体激光离解的作用都受两相的界面相互作用的影响，即与聚合物基体的性质、后处理等有关，热处理后两相界面的变化对PS和AS体系的炭化影响不大，但PS体系中银团簇的最大原子聚集数减小；而对PMMA体系则基本上消除了激光炭化。

Flowers axillary, solitary or in cymose clusters, sometimes aggregated into terminal spikes.

花腋生的，单生或在聚伞状簇生的，有时聚生成顶生的穗状花序。
