针对激光熔覆过程中易出现的熔覆层开裂的问题,采用了单向送粉双向扫描激光熔覆工艺,较好地抑制了熔覆层的开裂.通过对激光熔覆过程温度场、应力场进行计算分析,发现采取单向送粉单向扫描工艺时,熔覆层顶部以及与基体接合处会出现明显的应力集中现象,且应力水平较大,而采取双向扫描工艺后,熔覆层内拉应力水平显著降低,且熔覆层顶部的应力集中现象基本消除.在进行以45钢为基体,熔覆Ni60合金粉末的激光熔覆试验中,应用该熔覆方法后,发现无论是单道熔覆还是多道搭接熔覆,皆可有效地避免熔覆层开裂.结果表明,该方法对于裂纹的抑制作用是有效且可行.

对含有十溴联苯醚阻燃剂的废旧电视机外壳(高抗冲聚苯乙烯,HIPS)进行了真空热解实验,考察了不同升温条件下阻燃剂分解和塑料热解行为的差异.结果表明:与快速热解相比,两级慢速升温热解方式更有利于溴代产物的选择性分布,促使大量的高溴代物富集在第一段热解产物中,而相对较少的低溴代物出现在第二段热解产物中;同时此热解方式可显著影响两段液体产品中主要产物的分布和产率,慢速升温可产生更多的单苯环物质,从而避免了在高温条件下聚合副反应的发生.

Heterogeneous catalysts with ultrafine or nano particle size have currently attracted considerable attentions in the chemical and petrochemical production processes, but their large-scale applications remain challenging because of difficulties associated with their efficient separation from the reaction slurry. A porous ceramic membrane reactor has emerged as a promising method to solve the problem concerning catalysts separation in situ from the reaction mixture and make the production process continuous in heterogeneous catalysis. This article presents a review of the present progress on porous ceramic membrane reactors for heterogeneous catalysis, which covers classification of configurations of porous ceramic membrane reactor, major considerations and some important industrial applications. A special emphasis is paid to major considerations in term of application-oriented ceramic membrane design, optimization of ceramic membrane reactor performance and membrane fouling mechanism. Finally, brief concluding remarks on porous ceramic membrane reactors are given and possible future research interests are also outlined.

作者： chen Yong-lie, chen Xu-dong and LIANG Zhao-xi (Institute of Polymer Science, Zhongshan University, Guangzhou, 510275)

Two iron-arene complex photoinitiators with different substituents in arene ligands were synthesized, their activities in initiating photopolymerization of cyclohexene oxide (CHO) were compared with that of IRGACURE 261, a commercialized photoinitiator from Ciba-Geigy. A higher activity was found when the arene ligand was substituted with a stronger electron donating group. For the system initiated by IRGACURE 261 the concentration of active centers in CHO polymerization was determined and it was found that the concentration is maximum at around 35℃. The post (dark) polymerization was significant, the polymerization yield decreased with the increase of irradiation temperature and increased with the increase of post polymerization temperature. The results are interpreted based on the mechanism proposed by Lohse, et al..

Background The latest version of the American Joint Committee on Cancer （AJCC） TNM staging system has not comprehensively evaluated the impact of tumour length on survival in patients with esophageal squamous cell carcinoma. Our study explored the relationship between tumour length and clinicopathological characteristics as well as long-term survival. Methods All 202 cases of esophageal resections done from January 1, 2004 to December 31, 2008 in Huashan Hospital, Fudan University were reviewed and followed up. Results Patients with tumour length 〉3 cm were related to more advanced tumour stage （χ2=55.9, P 〈0.001）, more metastatic lymph nodes （χ2=14.6, P 〈0.001）, increased metastatic lymph node ratio （χ2=16.1, P 〈0.001） and worse overall TNM stage （χ2=48.1, P 〈0.001）. Univariate and multivariate analyses indicated that tumour length was a significant prognostic risk factor （95% CI 0.235-0.947, P=-0.035）. Subgroup analyses disclosed that tumour length was a valuable prognostic predictor in patients with lower T stage, absence of metastatic lymph nodes and lower TNM stage. Conclusions Esophageal tumour length is a predictive factor for long-term survival especially for lower tumour stage, absence of metastatic lymph nodes and lower TNM stage patients. Tumour length should be incorporated in the staging system as an important grouping factor for better prognostic evaluation.

Based on the phase-space information obtained from a multi-phase transport model within the string melting scenario for strange and antistrange quarks, we study the yields and transverse momentum spectra of (?) mesons and Ω baryons as well as their anisotropic flows in Au+Au collisions at RHIC using a dynamical quark coalescence model that includes the effect due to quark phase-space distributions inside hadrons.

轨道是限制铁路桥梁减隔震装置在地震中发挥耗能作用的一个可能因素。为了分析轨道约束对铁路减隔震桥梁地震响应的影响,以高速铁路客运专线上两座采用不同减隔震装置的32m简支桥梁为对象,用非线性弹簧单元模拟道床的纵向位移阻力关系,建立地震作用下桥梁与轨道共同作用的线桥一体化计算模型,对其进行弹塑性地震响应分析。结果表明:轨道对铁路减隔震桥梁纵向自振频率的影响不可忽视,影响程度与道床阻力系数有关,随着道床阻力系数增加,结构的自振频率增大;轨道约束虽然对墩底的最大地震剪力影响不大,但对桥梁纵向地震位移和减隔震装置变形的影响出现增大和减小两种现象,设计时应考虑轨道约束产生的不利因素,适当提高相邻梁间的结构允许相对变形要求。
