, 1954 【緒言】 1949年に山形県で作られた輸出用平核無干柿の果肉の表面近くに、点々と白味がかった異状な斑点が現われて、外観を損じたため輸出に困難を来たした。著者の一人須佐は、昭和24年度産の平核無干柿に現われた白斑が、加工工程中に出来たのか、生理的に形成されたものかを調査中の処、産地西田川郡袖浦村黒森地帯の河岸地産の生果に、既に出ていた事を現地に於て確認し、若しこの病斑が毎年発生すれば、輸出用として不適当となり輸出振興上に重大な支障を来たすのでこれを解決しようとして、須佐が主任研究者となり ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...

Shuitu Baochi Xuebao, 2007 各种试验土壤腐殖酸的紫外吸收曲线相似,但吸收峰强度和E 465/E 665值差异较大,腐殖酸的腐殖化程度由大至小排序为：紫色潮土HA〉黄壤HA〉中性紫色土HA〉酸性紫色土HA,说明它们组成相似,结构和性质有差异。在此基础上,研究它们对辛硫磷水解的影响。结果表明,不同来源土壤腐殖酸均阻碍辛硫磷的水解,但它们的影响程度有明显的差异。腐殖酸溶液浓度越大,辛硫磷水解速率越慢,相同腐殖酸浓度下以腐殖化程度较高的紫色潮土的作用最大。初步说明辛硫磷的水解速率与土壤腐殖酸的浓度和腐殖化程度有关。

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Thermally driven hydrogenation of CO2 to light olefins (C2=–C4=) using metal oxide‐zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid‐site inactivation, and surface carbon poisoning.

Shuitu Baochi Xuebao, 2019 以东乌珠穆沁旗的草原砂土为研究对象，采用正交试验设计的方法，研究了土壤/溶液（固/液）、初始汞浓度、溶液pH、腐殖酸、硝酸钠浓度对东乌珠穆沁旗草原砂土吸附HgCl2的影响。结果表明：固/液越小，初始汞浓度越大，土壤吸附能力越强；土壤对汞的吸附量随溶液pH，外源腐殖酸浓度，硝酸钠浓度的增大而呈现先增大后减小的趋势，当溶液pH为7.5，外源腐殖酸浓度为0.6 mg/g，硝酸钠浓度为0.08 mg/L时，土壤对汞的吸附量分别达到最大。影响砂土吸附HgCl2的因素大小依次为初始汞浓度 > 固/液 > pH ...

Preparation and hypoglycemic activity of selenium－enrichedasini corri colla－inulin chewable tables [PDF]
, 2016 以阿胶、菊粉、富硒卡拉胶等为原料,依次经过原料的干燥、混匀、制软材、干燥、过筛、压片后制得富硒阿胶-菊粉咀嚼片。本文概述了富硒阿胶-菊粉咀嚼片的制备工艺流程并对优化过程进行描述,研究了其降血糖活性功能。研究结果表明:阿胶、菊粉、富硒卡拉胶、硬脂酸镁的添加量分别为24.5%、73.5%、1%、1%,以95%的乙醇溶液为黏合剂,可制得表面光滑、色泽均匀,独特风味的富硒阿胶咀嚼片。小鼠降血糖实验结果表明,样品组小鼠在灌胃处理30 d后随机血糖有显著降低,与二甲双胍作用相当,因而该产品具有显著降低血糖水平功效。
