Using examples from various institutions, publishers, and services, I will discuss the features, functions, concatenations of collections, as well as digital objects in various genres and from various sources that we can see now in limited information environments as indicators of what we cybrarians could be doing for scholars and students in the future.

通过来自不同机构、出版商和服务提供者的实例，将讨论在各种信息环境中已能看到的各种功能、特性、资源集合、各种形态和不同来源的数字对象，以此来反映我们Cybrarians在未来能够为学生和学者所提供的服务。

The results show that the as-synthesized chalcone-containing copolymers are a kind of thermosensitive polymer with a lower critic solution temperature and the LCST of the copolymer decreases with the increase of the chalcone content in the copolymer. With the increase of the solvent polarity, both the maximum absorption wavelength and the fluorescence emitting wavelength of the chalcone-containing copolymers redshifts, and the intensity of fluorescence first increases, then decreases, which exhibits solvent polarity sensitive fluorescence properties.

结果表明，侧链查尔酮共聚物是一类具有低临界溶解温度的温敏性聚合物，其LCST温度随着共聚物中查尔酮含量的增加而降低；随着溶剂极性的增加，侧链查尔酮共聚物的紫外-可见最大吸收波长红移，其荧光发光波长红移并且发光强度先增强后降低，具有溶剂极性敏感的荧光特性；同时对比侧链查尔酮共聚物水溶液低温和高温下的荧光，发现低温下几乎无荧光，高温下其荧光得到明显增强，其荧光具有可逆的温度&开/关&特性。
