On the Double-Reference Character of ＂Hexagram＂ Names in the Yijing： Engaging Fregean＆Kripkean Approaches to the Issue of How Reference Is Possible

引用

Frontiers of Philosophy in China 2014年第4期9卷 523-537页

作者： mou bo Department of Philosophy San Jose State University San Jose CA 95192 USA

This paper aims to examine the general issue of how reference is possible in philosophy of language through a case analysis of the ＂double reference＂ semantic-syntactic structure of ideographic hexagram （guaxiang 卦象） names in the Yijing text. I regard the case of the ＂hexagram＂ names as being quite representative of the ＂double-reference＂ semantic-syntactic structure of referring names. I thus explore how the general morals drawn from this account of ＂hexagram＂ names can engage two representative approaches, the Fregean and Kripkean ones, and contribute to our understanding and treatment of the issue of reference.

Effects of neutral salt and alkali on ion distributions in the roots,shoots,and leaves of two alfalfa cultivars with differing degrees of salt tolerance

引用

Journal of Integrative Agriculture 2017年第8期16卷 1800-1807页

作者： WANG Xiao-shan REN Hai-long WEI zen-wu WANG Yun-wen REN Wei-bo Department of Grassland Science College of Animal Science and TechnologyYangzhou UniversityYangzhou 225009P.R.China Institute of Grassland Research Chinese Academy of Agricultural SciencesHohhot 010000P.R.China Department of Grassland Science College of Animal Science and TechnologyChina Agricultural UniversityBeijing 100193P.R.China

The effects of neutral salt and alkali on the ion distribution were investigated in two alfalfa （Medicago sativa L.） cultivars, including Zhongmu 1, a high salt-tolerant cultivar, and Algonquin, a low salt-tolerant cultivar. The alkali stress expressed more serious growth inhibition than the neutral salt stress at the same Na＋ concentration. Compared with Algonquin, Zhongmu 1 did not exhibit a higher alkali tolerance under the Na2CO3-NaHCO3 treatment with the low Na＋ concentration （50 mmol L-l）. The alkali increased the accumulation of Na＋, Ca2＋, and Mg2＋ in the root and changed the Ca2＋ and Mg2＋ balance in the entire alfalfa plant. The salt and alkali stresses decreased the K＋ and Fe3＋ contents of the roots and leaves, the root Mn2＋ content, and the shoot Zn2＋ content, but they increased the Fe3＋ accumulation of the shoots, the shoot and leaf Cu2＋ contents, and the leaf Zn2＋ content in both alfalfa cultivars. Based on the results obtained under the conditions of this experiment, we found that the salt and alkali stresses reduced the plant growth in both alfalfa cultivars, while the alkali caused a stronger stress than the neutral salt in alfalfa. Thus, we conclude that under hydroponic conditions, the deleterious effects of the alkali on plants are due to the distribution change of some trophic ion balance in the roots, shoots, and leaves of the plants by causing of Na＋, CO3^2-, and/or HCO3- stresses.

植物多样性显著影响生态系统的结构和功能,对土壤有机碳固存起至关重要作用。以往植物多样性对土壤有机碳的影响多在人工控制植物多样性条件下进行,表明高植物多样性显著促进土壤有机碳积累。而在自然草地生态系统中,植物多样性对土壤有机碳影响的研究相对薄弱。本研究选取了青藏高原东北部15个典型高寒草甸作为研究样地,通过测定植物地上及地下生物量、土壤pH值、土壤微生物量碳氮、土壤有机碳、颗粒有机碳及矿物结合态有机碳、全氮及全磷等,旨在探究自然条件下植物多样性对土壤有机碳固存的影响,为土壤碳储量的变化及草地的科学管理提供理论依据。结果表明,植物多样性显著提高了植物盖度和地上生物量(P<0.01),而对不同土层(0~20 cm和20~40 cm)地下生物量无显著影响;在0~20 cm和20~40 cm土层中,植物多样性的增加显著提高了土壤微生物量碳和有机碳含量(P<0.05),而对不同土层微生物量氮无影响;通过对土壤有机碳分组发现植物多样性和土壤矿物结合态有机碳含量呈显著正相关(P<0.01),而和土壤颗粒有机碳含量无相关性。综上,在青藏高原高寒草甸,自然条件下较高的植物多样性对土壤有机碳含量有显著促进效果,这种促进效果主要表现在矿物结合态有机碳含量的增加。本研究为草地生态系统植物多样性与土壤碳库间的相互关系提供新见解及理论基础。

Magnetic core-shell microparticles for oil removing with thermal driving regeneration property

Petroleum Science 2023年第4期20卷 2531-2544页

作者： Shi-Hao Chen Chuan-Lin mou Wen-Long Ma Ya-Dong Li Zi-Yu Tang Hong-bo Deng College of Chemistry and Chemical Engineering Southwest Petroleum UniversityChengduSichuan610500China

Here, we report the construction of magnetic core-shell microparticles for oil removal with thermal driving regeneration property. Water-in-oil-in water (W/O/W) emulsions from microfluidics are used as templates to prepare core-shell microparticles with magnetic holed poly (ethoxylated trimethylolpropane triacrylate) (PETPTA) shells each containing a thermal-sensitive poly (N-Isopropylacrylamide) (PNIPAM) core. The microparticles could adsorb oil from water due to the special structure and be collected with a magnetic field. Then, the oil-filled microparticles would be regenerated by thermal stimulus, in which the inner PNIPAM microgels work as thermal-sensitive pistons to force out the adsorbed oil. At the same time, the adsorbed oil would be recycled by distillation. Furthermore, the adsorption capacity of the microparticles for oil keeps very stable after 1st cycle. The adsorption and regeneration performances of the microparticles are greatly affected by the size of the holes on the outer PETPTA shells, which could be precisely controlled by regulating the interfacial forces in W/O/W emulsion templates. The optimized core-shell microparticles show excellent oil adsorption and thermal driving regeneration performances nearly without secondary pollution, and would be a reliable green adsorption material for kinds of oil.

Nucleic acid extraction is one of the bases in molecular biology and it is the indispensable process for nucleic acid detection. Due to its excellent characteristics, the method based on magnetic beads has become one of the main methods for nucleic acid *** this research, we have developed a rapid high-quality universal nucleic acid extraction kit based on magnetic beads(MBs) and named it MB-100. Some factors affecting nucleic acid extraction were optimized, such as particle size of MBs, surface groups of MBs and lysis time. Results demonstrated that micron-grade MBs@SiO_2 particles were much more appropriate for nucleic acid extraction and lysis time was 5 min. Simultaneously, the performance of MB-100 was explored. Results showed that it had much higher extraction efficiency than other two commercial kits, and the following PCR reaction also had much higher amplification efficiency.
