论新安理学家的家学传统

家学传统是在新安理学家中普遍具有的一种学术文化现象,新安理学家的家学传承方式多样;传承内容多为朱子“论定”之经学;其家学传统对新安理学和徽州社会具有一定积极影响,同时,也有其局限性。     

黑龙江鹿鸣钼矿床流体包裹体特征

鹿鸣钼矿床位于小兴安岭-张广才岭成矿带中南部.钼矿体产于二长花岗岩与花岗斑岩的接触带内,钼矿化主要载体为石英脉,呈脉状、网脉状分布于矿体的内部.研究了主要含矿石英脉体中流体包裹体的特征,结果表明:包裹体相态类型主要为气液两相,矿床的成矿温度峰值分别为400,220℃,盐度为19%~144%,成矿压力平均为18MPa,成矿深度为09~28km,成矿流体成分富含CO2,H2O,CH4等多种气态组分,以及Na+,Ca2+,SO2-4,Cl-液态组分;矿床初始流体来源于岩浆热液,成矿后期受大气降水的混入.矿床成因类型应划归为与中酸性侵入岩浆活动有关的中高温斑岩型钼矿床.     

分子筛催化合成乳酸异戊酯的研究

用ＨＺＳＭ－５,Ｍｏ／ＨＺＳＭ－５,Ｆｅ／ＨＺＳＭ－５（３８）分子筛催化合成乳酸异戊酯,以Ｍｏ／ＨＺＳＭ－５分子筛的催化性能最好。当Ｍｏ／ＨＺＳＭ－５分子筛催化剂用量为１ｇ／ｍｏｌ乳酸,乳酸与异戊醇的摩尔比为１：１．２,控制反应温度为１５０℃时,乳酸异戊酯的产率可达９３．８％,催化剂可以回收连续多次使用,在６ｈ内产率仍可保持在９３％左右。     

Hydrogen absorption-desorption characteristic of (Ti0.85Zr0.15)1.1Cr1-xMoxMn based alloys with C14 Laves phase

The microstructure and hydrogen absorption-desorption characteristic of (Ti_0.85Zr_0.15)_1.1Cr_1-xMo_xMn (x ?= ?0.05, 0.1, 0.15, 0.2 ?at.%) alloys were investigated. The results showed that the corresponding alloys were determined as a single phase of C14-type Laves structure. With the increase of Mo content, the maximum and reversible hydrogen absorption capacity decreased, the slope factor H_f increased. Among the studied alloys, (Ti_0.85Zr_0.15)_1.1Cr_0.95Mo_0.05Mn had the best overall properties for practical application of hydrogen storage materials. The maximum and reversible hydrogen storage capacity were 1.76 ?wt% and 1.09 ?wt%, the slope factor H_f was 0.51, and its dissociation enthalpy (ΔH_d) and entropy change (ΔS_d) were 23.1 ?kJ ?mol^?1H₂, 93.8J ?K^?1mol^?1H₂ at 303K, respectively. By studying the dissociation pressures of the synthesized metal hydrides, it was found that Mo had a special effect on the dissociation pressure of Ti–Zr–Cr–Mo–Mn alloys. Among the four alloys, (Ti_0.85Zr_0.15)_1.1Cr_0.95Mo_0.05Mn alloy had the largest hydrogen absorption capacity and the fastest hydrogen desorption rate, which can meet the commercialization demand of hydrogen fuel cell hydrogen supply system.
