目的评估大语言模型解答儿童哮喘问题的表现,全面了解其提供儿童健康相关信息的质量,并识别其局限以促进模型的改进。方法制订出60个儿童哮喘相关的常见问题,分别向2种在国内向公众开放使用的文心一言、智谱清言大语言模型提问。由3名儿科哮喘专业医师采用盲法评估大语言模型的回答质量。结果在准确性、理解力、可靠性和逻辑性维度方面,文心一言得分较高;在安全性维度方面,智谱清言的得分较高。对比5个不同的维度的得分发现,大语言模型在理解力、可靠性、逻辑性方面得分较高,而在准确性与安全性方面相对不足。结论大语言模型在儿童哮喘患者教育中的应用能够为儿童哮喘患者及其家长提供有益的参考。然而,当前大语言模型技术在准确性、安全性等方面仍存在一定的局限性,需要进一步改进和优化。

A novel tetra-nuclear Tb-organic network,named as [Tb_(4)(2-pyia)_(6)(HAc)_(0.5)(2,2'-bipy)(H_(2)O)_(4.5)]·2,2'-bipy·H_(2)O(1),was synthesized hydrothermally based on 5-(pyridin-2-ylmethoxy) isophthalic acid(H_(2)pyia) and 2,2'-bipyridine(2,2'-bipy) ligands,and characterized by single crystal X-ray diffraction,thermogravimetric(TG) analyses,powder X-ray diffraction(PXRD) and infrared(IR) technology.1 possesses a two-dimensional network based on the tetra-nuclear inorganic building units,and the π-πstacking interactions between the pyia^(2-) ligands and the guest 2,2'-bipy molecules play an important role in the forming of 3D supramolecular structure.1 exhibits excellent fluorescent sensing performance for Fe^(3+)(1.26×10^(-8) mol/L),Cr_(2)O_(7)^(2-)(8.1×10^(-7) mol/L),2,4,6-trinitrophenol(TNP)(2.71×10^(-8) mol/L)and tetracycline(TCT)(2.76×10^(-7) mol/L) in aqueous solution with lower detection *** sensing mechanisms of 1 were investigated by density functional theory(DFT) calculations,ultraviolet-visible(UV-Vis) diffuse reflectance spectroscopy,PXRD and fluorescent lifetime *** activated product of 1 was prepared by heating at 255℃ under constant pressure and used to photo-catalytically degrade *** 1 and the activated one have good photocatalytic degradation performance for TCT with degradation rates of 84.29% and 96.07%,*** photocatalytic mechanisms were discovered by UV-Vis diffuse reflectance spectroscopy and radical trap *** Tb-organic framework might be an excellent multifunctional fluorescent sensor and a good photocatalytic agent for TCT degradation in the future.

In order to ensure e-government construction healthily,rapidly and orderly develop,an e-government maturity model（EGMM）is proposed based on a software capability maturity model （CMM）and a project management maturity model（PMMM）. Five levels of maturity in e-government development process are constructed,which include network infrastructure,information serving,information interactive,information sharing and comprehensive *** index system of e-government maturity is put forward,and then an e-government maturity levels evaluation method is presented,which can provide clear,detailed and efficient decision information and investment directions of e-government for *** EGMM and its maturity evaluation method are helpful for improving the construction of e-government.

The SiO2inverse opal photonic crystals (PC) with a three-dimensional macroporous structure were fabricated by the sacrificial template method， followed by infiltration of a pyrene derivative， 1-(pyren-8-yl)but-3-en-1-amine (PEA)， to achieve a formaldehyde-sensitive and fluorescence-enhanced sensing film. Utilizing the specific Aza-Cope rearrangement reaction of allylamine of PEA and formaldehyde (FA) to generate a strong fluorescent product emitted at ～480 nm， we chose a PC whose blue band edge of stopband overlapped with the fluorescence emission wavelength. In virtue of the fluorescence enhancement property derived from slow photon effect of PC， FA was detected highly selectively and sensitively. The limit of detection (LoD) was calculated to be 1.38 nmol/L. Furthermore， the fast detection of FA (within 1 min) is realized due to the interconnected three-dimensional macroporous structure of the inverse opal PC and its high specific surface area. The prepared sensing film can be used for the detection of FA in air， aquatic products and living cells. The very close FA content in indoor air to the result from FA detector， the recovery rate of 101.5% for detecting FA in aquatic products and fast fluorescence imaging in 2 min for living cells demonstrate the reliability and accuracy of our method in practical applications.

To provide efficient monitoring of web service-based business processes, a web service proxy （WS- proxy） is developed to monitor business activities by monitoring the enactment of services. WS-proxy is deployed as an intermediary between internal business processes and external service providers, and it provides a single point of service access with the functions of message routing and content inspection. By using an XPath engine named WS-filter, performance indicators can be generated from service messages for assessing business performance. In the experiments, the feasibility of WS-proxy is verified and it achieves good performance in the monitoring work. The latency introduced by WS-proxy is only about 15% of the overall latency while extracting performance indicators just consumes less than one third of the processing time.

集体心灵现象泛指集体承担的各种意向性活动。作为一种心灵现象,集体心灵自然也面对是否物理可还原的问题。这一问题可以由以下论证得到回答。首先,不同于个体心灵,集体心灵只需被赋予特定的、有限的认知能力;其次,这些能力可以由成员的认知能力和集体活动的环境背景、组织方式得到说明;最后,物理主义能够说明这些要素和其组织的物理性。这一还原思路提示一个重要的诊断:传统的集体心灵还原论要求通过本体论个人主义对集体心灵进行还原,既忽视了集体性的物质特征,也在某种程度上神化了个人心灵的能力。物理主义所蕴含的恰当的物质主义洞见应可以取代传统的个人一集体的简单二分。
