以Cr_(3)C_(2)粉末作为碳源,海绵钛为基体,利用真空感应悬浮熔炼炉制备原位自生TiC/Ti复合材料。研究了Cr_(3)C_(2)添加量(3wt%、6wt%、9wt%)对复合材料微观组织和力学性能的影响。采用X射线衍射仪、扫描电子显微镜和透射电镜对不同Cr_(3)C_(2)添加量的复合材料的物相组成和微观组织结构进行表征。使用洛氏硬度计和室温拉伸性能试验机对复合材料的室温力学性能进行检测。结果表明:随Cr_(3)C_(2)添加量增加,TiC形貌从细长条状到等轴状再到枝晶状转变,基体组织从片层α’转变为针状马氏体α’,晶粒尺寸大幅度下降;复合材料的洛氏硬度从12.2 HRC提高至40.2 HRC,抗拉强度和伸长率均先升高后下降,当Cr_(3)C_(2)添加量为6.0 wt%时,抗拉强度和伸长率最大。

The feasibility of simultaneous water recovery,salt separation and effective descaling of hypersaline brine was investigated by diisopropylamine(DIPA)-based directional solvent extraction(DSE),using diluted/concentrated seawater with initial saline concentration range of 12–237 g/L at extraction temperatures of 5 and 15℃,*** water recovery shows an obvious boundary at saline concentration of 115 g/L under dual effect of specific water extraction efficiency and extraction *** Cl^(–) ion concentration in product water is in sharp contrast to the nearly complete removal of SO_(4)^(2–)and hardness ions,indicating that DIPA-based DSE process indeed achieved efficient separation and purification of Cl^(–) ion from hypersaline ***,the radical precipitation of Mg^(2+)and Ca^(2+)ions in form of Mg(OH)_(2)and CaCO_(3)demonstrates effective descaling potential,although it leads to more DIPA residues in dewatered raffinate than product ***,an exponential correlation between the Cl^(–) removal efficiency and specific water extraction efficiency further reveals the intrinsic relationship of water extraction process and transfer of Cl^(–) ion to the product ***,the study provides a novel approach for integrating the water recovery and separation of Cl^(–) ion from ultra-high-salinity brines with radical precipitation of Mg^(2+)and Ca^(2+) ions in one step.

目的探讨大鼠脊髓不同部位损伤后膀胱顺应性与膀胱神经生长因子（NGF）表达的关系。方法180只雌性SD大鼠按随机数字表分成3组,胸腰段损伤组60只,骶段损伤组60只,正常对照组60只。使用标准化脊髓损伤动物模型实验装置制备背侧脊髓损伤动物模型,胸腰段损伤组损伤部位为T10-L1,骶段损伤组损伤部位为S2-S4,对照组大鼠仅咬除棘突和椎板,不损伤脊髓。4周后作膀胱测压检测后,取出膀胱制备组织匀浆,酶联免疫吸附试验（ELISA）法测定NGF的表达量。结果 ①胸腰段损伤组以低顺应性膀胱为特征,骶段损伤组表现为高顺应性膀胱。②膀胱组织ELISA检测结果表明：胸腰段损伤组膀胱组织NGF表达量增加,骶段损伤组膀胱组织NGF表达量降低。③胸腰段脊髓损伤后膀胱顺应性和膀胱组织中NGF表达量呈负相关（r=-0.655,P〈0.05）;骶段脊髓损伤后膀胱顺应性和膀胱组织中NGF表达量呈负相关（r=-0.783,P〈0.05）。结论脊髓高位损伤后膀胱顺应性降低,膀胱组织NGF表达量升高;脊髓低位损伤后膀胱顺应性升高,膀胱组织NGF表达量降低;脊髓损伤后膀胱顺应性的改变与NGF的表达量呈负相关。
