簇

A novel series of naphthalimide dendrimers has been synthesized, into whose dendron novel specific function units are introduced. The absorption and fluorescence properties of the arrays were studied and discussed. Excitation of the terminal donor chromophores carbazole mainly results in the fluorescence of the core dye alone, whose efficiency is dependent on the dendrimer generation.

在树枝上引入特定的功能单元，将多个具有特定功能团连接起来，形成功能化树枝状周边分子团簇，然后将它们分别与核心色素萘酰亚胺相连接，合成新型周边树枝状功能化的有机发光材料。

Inflorescences polygamous, axillary in distal leaves, paniculiform, fascicled from many spikes; flower clusters alternate, usually a simple dichasium with bisexual flower in middle and sterile female flowers laterally.

花序杂性，在远轴叶上腋生，圆锥花序状，很多穗状花序簇生；花穗互生，通常有一简单的二歧聚伞花序，中间为两性花和两侧为不育雌花。

Inflorescences terminal and axillary, racemes subdigitate or axillary racemes sometimes solitary, spathate; racemes bearing pairs of unisexual awnless spikelets, female and male spikelets separated into different zones, axis fragile, especially in female zone; lateral racemes of digitate cluster entirely staminate, terminal raceme and solitary axillary racemes mixed, usually sterile spikelet pairs at base, then a zone with female sessile and sterile pedicelled spikelets, distally both spikelets of a pair staminate, uppermost spikelet pairs sterile.

花序顶生和腋生，总状花序或腋生总状花序有时单生，；总状花序着生单性awnless小穗，女性和男小穗分成不同区域，脆的轴，特别是女区域；侧总状花序的完全雄蕊花的指状簇生，顶生总状花序和单生总状花序混合，通常不育对在基部，一女的区域具无梗和不育pedicelled小穗，一雄蕊花的对，不育的最上部的小穗对的两小穗的上部的然后。

In the Windows operating system, we can use the Chkdsk command to view the hard disk partitions cluster size.

在 Windows 操作系统中，我们可以使用 Chkdsk 命令查看硬盘分区的簇大小。

Greater support fat16 partition, the disk capacity of each cluster is also greater, resulting in greater waste.

fat16支持的分区越大，磁盘上每个簇的容量也越大，造成的浪费也越大。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
