The effects of ultrafine WC(WC_(UF),0.5μm) or W(1μm) and C(0.3μm)(W+C)_(UF) additives on the densification,microstructure and mechanical properties of coarse-grained cemented carbides were compared ***,the cemented carbides with WC_(UF)/(W+C)_(UF) additives are almost fully densification to be higher than 99%,and the average grain size is kept above 2.8μ*** WC_(UF) additive assists grains to(truncated)trigonal prism shape by two dimensional(2D) growth,whereas the(W+C)_(UF) additive assists grains to rounded shape by three dimensional(3D) growth,lowers WC contiguity and increases face-centered-cubic *** hardness and bending strength of(75WC_(C)-15WC_(UF))-10Co are 86.6 HRA and 2 272 MPa,respectively,both higher than those of(75WC_(C)-15(W+C)_(UF))-10Co,which could be ascribed to the enhanced densification and unblemished ***,the fracture toughness of the(75WC_(C)-15(W+C)_(UF))-10Co is 23.5 MPa·m^(1/2),higher than that of the(75WC_(C)-15WC_(UF))-10Co due to the uniform WC-Co structure and flexible binder phase.

本文以景颇语中声调交替的致使动词为研究对象,试图从历史语言学的角度对该现象提出构拟和解释。本文论证了景颇语致使范畴的声调交替源自致使前缀脱落这一分析方法存在的问题,并参照基兰提支语言的相关现象提出了另外一种更可行的分析,即景颇语致使范畴的声调交替不是因致使前缀脱落造成的变化,而是施用态-t后缀脱落留下的痕迹。

Lattice thermal conductivity, κL, is a fundamental parameter for evaluating the performance of thermoelectric materials. However, the predicted value of κL based on the Debye dispersion model is often overestimated compared with the experimentally determined *** researchers have attempted to modify the theoretical model and have sought more reliable results. In this review,the recent progress in the study of phonon dispersion models is summarized and we propose that the lattice thermal conductivity can be most accurately determined by using the modified sinusoidal phonon dispersion ***, experimental methods that have the potential to reduce a thermoelectric material's κLare reviewed, for example, methods that generate standing waves or anharmonic lattice vibrations. A high concentration of standing waves and anharmonic lattice vibrations can effectively suppress excessive κL. Finally, this review presents the challenges of sinusoidal phonon dispersion when applied to real materials, which are often complicated and therefore time-consuming, especially when dealing with material defects.

采用化学共沉淀−高温氢还原工艺制备纳米Ni均匀包覆的WC复合粉体(简称CM-WCN),在1450℃下真空烧结1 h,获得WC−Ni硬质合金,并对其组织及性能进行研究。结果表明,CM-WCN硬质合金中WC的平均晶粒度为3.0~3.8μm,仅观察到少量孔隙。CM-WCN−10%Ni(质量分数)的相对密度、硬度及抗弯强度分别为99.63%、HRA 86.5及1860 MPa,CM-WCN−12%Ni(质量分数)的最高冲击韧性为6.17 J/cm^(2),优于本文中手混法制备的WC−Ni(HM-WCN)硬质合金及文献报道同类合金的性能。由于结构均匀性及低孔隙率,CM-WCN硬质合金具有优异的力学性能,其主要断裂模式为穿晶断裂,并伴随黏结相塑性形变。此外,当Ni含量为6%~12%(质量分数)时,CM-WCN比HM-WCN硬质合金的耐腐蚀性能更好。

Introduction: Despite the progress recorded at the level of transfusion safety in Côte d’Ivoire, much remains to be done, particularly at the level of the medical selection of blood donors. The objective of the study was to make an assessment of the pre-donation capillary hemoglobin dosage for the year 2020 of the fixed collection, of the Blood Transfusion Center of Yamoussoukro. Method: This is a retrospective study that took place at the Yamoussoukro Blood Transfusion Center. The data collection related to all old and new blood donors were deemed suitable for the fixed collection of the year 2020. The method chosen for the pre-donation control is that of the portable hemoglobinometer of the HémoCue® type, more precisely 201+. Results: Of the 1160 blood donors in the study, the pre-donation hemoglobin level was not measured in 787 (67.8%) subjects of either sex. Of the subjects who had a pre-donation hemoglobin level performed, 97 (26%) blood donors had a sub-standard hemoglobin level, including 15 females and 82 males. Conclusion: Pre-donation hemoglobin testing of blood donors is effective in Yamoussoukro. However, efforts must still be made to improve the quality of the blood collected and to protect blood donors.

Direct determination of the oxidative potential in exhaled air(OPEA)as a biological indicator of the redox balance status in airways requires an extremely sensitive sensing approach to counterbalance the high dilution of the exhaled air *** opposite to standard colorimetric assays based on Beer-Lambert Law,the use of simple multiscattering-enhanced absorbance(MEA)strategy results in an improved photonic sensing *** on this strategy and using the ferrous-xylenol orange assay,analytical performances allowing the detection of 3 pmol of H_(2)O_(2) could be *** comparative analysis of photometric configurations–standard vs MEA–highlights the large absorbance gain obtained for tiny H_(2)O_(2) amounts–from 0 to 30 pmol–whereas similar sensing trends are observed at higher concentration *** automated introduction of exhaled air sample into the reaction compartment via needle-impinger coupled with the MEA-based photonic cell enables ultrasensitive determination of OPEA in short time(<5 min).A pilot study conducted on healthy subjects(n=22)and chronic obstructive pulmonary disease(COPD)patients(n=23)volunteers shows a significant increase of the OPEA for COPD versus controls and strong negative correlation between OPEA and spirometry parameters(Tiffeneau index:FEV1/FVC)for ex-/*** perspectives to assess inflammatory episodes in obstructive lung diseases are thus made possible using this sensing approach.

西夏语的名词性谓语

民族语文 2008年第4期 37-40页

作者： [法]向柏霖巴黎第五大学法国

在羌语支语言中,包括西夏语,名词不能直接当谓语,而且也不能与动词人称范畴的后缀连用:所有名词都必须带系词,人称后缀附加在系词上.然而,笔者在西夏文文献《类林》中发现了一个反例,证明这一条原則有少数例外。

比较几个语系的相关数据可以看出鼻化特征的转移发生在音节首辅音丛和其后的元音之间。本文总结了迄今为止发现的数据,并针对一套汉藏语做了新的分析。显示这种演化在两个方向同时出现:从辅音声母到其后的元音出现在壮侗语系(台-卡岱语系)、南亚语系、汉藏语系、尼日尔-刚果语系(克瓦语)和印欧语系(凯尔特语)中;从元音向辅音声母的转移出现于苏语。仔细检验演化的条件,带出一条(规则的)不对称性。大多数情况下鼻化特征的转移是从辅音声母到其后的元音。相反方向的有规律的变化常常要附加下面任意一条对鼻音的限制条件:(i)鼻辅音为非音位性(语境可预测);或者(ii)鼻辅音后的鼻元音和口元音的对立发生中和(更倾向于鼻元音)。
