目的:比较栀子不同炮制饮片对四氯化碳(CCl4)致急性肝损伤的保护作用,为栀子不同饮片合理选择提供实验依据。方法:采用四氯化碳致大鼠急性肝损伤模型,测定大鼠血清中ALT、AST、TBIL、DBIL、TBA、LDH、ADA、PA、TP、ALP和肝组织中SOD、MDA的水平,并对肝组织进行病理学检查。结果:栀子不同炮制饮片组中AST、ALT、TBA、ADA、LDH、MDA生化指标均具有显著改善(P<0.05),但对SOD、ALP无影响,肝组织损伤有不同程度减轻。结论:栀子不同炮制饮片均具有降酶保肝作用;但栀子仁较栀子皮的降酶保肝作用强,而栀子生品较炒焦饮片降酶保肝作用更强。

在百年未有之大变局下,人类正在迎来以数字技术为代表的新一轮科技革命和产业变革,形成以数字基础、数字政府、数字社会、数字经济、数字能力为内容的数字生态。数字生态不断催生新技术、新产业和新动能,促进新质生产力发展,推动新质生产关系形成。当前,我国农业正面临着传统与现代并存二元结构转型升级关键期,必须充分发挥数字技术破解农业迂回生产分工难和产业组织集聚难的作用,以数字生态及与之相适配的制度组态推动农业新质生产力衍生与发展。基于此,以全国统一大市场建设为契机,运用生产力与生产关系的辩证关系原理,构建制度组态、数字生态与农业新质生产力培育的理论机制,综合运用必要条件分析法与动态定性比较分析法,利用我国30个省份(不包括西藏和港澳台地区)2019—2022年面板数据进行案例分析。定性比较分析法的单个必要性分析表明,数字生态要素的有效协同是培育高农业新质生产力的必要条件;必要条件分析表明,低数字能力与低数字经济制约农业新质生产力的培育;定性比较分析的条件组态充分性分析表明,培育农业新质生产力必须依靠数字生态要素及其匹配制度要素的有效组合,实施政府主导型、政府-市场双轮驱动型和政府-市场-社会三轮驱动型的组态路径。进一步加快农业新质生产力发展,应充分发挥全国统一大市场建设的数字化赋能作用,因地制宜选择农业新质生产力培育的组态路径,着力推动工业颠覆性技术在农业领域的广泛应用,大力加强农业数字化与数字化农业创新能力建设,全面深化以新质生产关系为导向的农业体制改革。

作者： Xin WANG shao-ze luo guang-sheng LIU Lu-chen ZHANG Yong WANG State Key Laboratory of Hydrology-Water Resources and Hydraulic Engineering Nanjing Hydraulic Research Institute Beijing Oriental Yuhong Waterproof Technology Co. Ltd.

In this study, several kinds of flexible protective materials sprayed with polyurea elastomers （hereinafter referred to as polyurea elastomer protective material） were adopted to meet the abrasion resistance requirement of hydraulic structures, and their abrasion resistances against the water flow with suspended load or bed load were studied systematically through tests. Natural basalt stones were adopted as the abrasive for simulation of the abrasion effect of the water flow with bed load, and test results indicate that the basalt stone is suitable for use in the abrasion resistance test of the flexible protective material. The wear process of the polyurea elastomer protective material is stable, and the wear loss is linear with the time of abrasion. If the wear thickness is regarded as the abrasion resistance evaluation factor, the abrasion resistance of the 351 pure polyurea is about twice those of pure polyurea with a high level of hardness and aliphatic polyurea, and over five times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with suspended load. It is also about 50 times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with bed load. Overall, the abrasion resistance of pure polyurea presented a decreasing trend with increasing hardness. Pure polyurea with a Shore hardness of D30 has the best abrasion resistance, which is 60 to 70 times that of high-performance abrasion-resistant concrete under the abrasion of the water flow with bed load, and has been recommended, among the five kinds of pure polyurea materials with different hardness, in anti-abrasion protection of hydraulic structures.

为了对淤泥和建筑垃圾进行处置,实现二者的共同资源化利用,在室内和现场分别对淤泥进行固化试验。将建筑垃圾作为骨料按淤泥质量比的15%添加到淤泥中,再向淤泥中加入淤泥固化剂,通过机械搅拌的方式将淤泥与建筑垃圾、固化剂混合均匀,然后对固化土进行养护。室内试验结果表明,当固化剂掺量为8%时,固化淤泥土强度较高,养护28 d后,室内无侧限抗压强度可达320 kPa;在现场试验中,静力触探试验和平板荷载试验表明,固化剂对淤泥的固化效果明显。将低剂量固化剂添加到淤泥中,固化淤泥土强度较低,骨料的架构作用不明显;当固化剂掺量为8%时,固化土的强度较高,骨料的架构作用有利于提升固化淤泥土的承载力,土体的承载力特征值可达325kPa,架构作用对固化淤泥土强度的提升率为71.05%,可实现淤泥和建筑垃圾的同步资源化利用。
