摘要： Of all the sectors capable of starting a profound domino effect that would touch the entire Chinese economy,the property market is the clearest frontrunner.For this reason,even the subtlest tweaks to real estate regulatory policies are often intensely scrutinized for possible broader economic implications.Scouring changes in policy tone seems especially imperative in the wake of the Evergrande crisis,as a debt crunch implicating some of China’s biggest property developers is awakening homebuyers and investors to a seismic shift in the real estate sector.

摘要： The property theory of Chinese materia medica is one of the foundations of traditional Chinese medicine.The property of Chinese materia medica(PCMM)is a multi-dimensional expression of the effect of Chinese materia medica(CMM),and it is related to the clinical prescription that fully reflects the clinical effect evaluation of CMM in a holistic,systematic,and scientific way.This paper discusses the source,development,and application of the PCMM by considering not only the five dimensions that constitute the PCMM but also the recognition of the human body and disease as given in traditional Chinese medicine.This paper aims to provide theoretical guidance for the rational use and development of CMM.

摘要： Pure cotton low-twist single yarn has good softness,bulkiness,and wearing comfort,but its lower strength makes the yarn break easily during the spinning process,which seriously affects the spinning effect and progress.The addition of long-staple cotton helps to increase the average length and uniformity of the raw fiber,thereby improving the breaking load and spinnability of pure cotton low-twist single yarn.In this study,the addition of long-staple cotton,the twist factor,and the twist direction were used as variables to spin 22 kinds of combed 14.6 tex pure cotton low-twist single yarn with spinnability,and the breaking load,the hairiness,and the unevenness of the yarn were tested.The result shows that the spinnability of pure cotton low-twist single yarn is mainly related to the breaking load,and with the increase of the twist factor,the breaking load of low-twist single yarn shows an obvious upward trend.When the proportion of long-staple cotton is 70%,the breaking load of low-twist single yarn is the largest,and the harmful hairiness index and unevenness of the yarn are significantly improved.

摘要： Characterization of materials and devices is fundamental to the understanding of structure-property relationship and improving device performance. Driven by the rapid progress achieved in semiconductors research, advanced characterization techniques at high spatial resolution are being developed.

摘要： Nanoscale structures exhibit excellent physical,chemical,catalytical and mechanical properties,mainly due to their very high surface contributions at very small length scales in nanoscopic dimensions.Nanoscale structures from different materials have been successfully grown using various methods and their structure-property relationships have also been understood up to some extent using state-of-the-techniques.Despite of the huge research effort,the versatile use of nanostructures in day-to-day technologies is limited.The nanoscale structures involve complex handling and integration processes with respect to their utilizations in real applications.Appropriate surface accessibility,wide and unique utilization,and cost-effectiveness are the main challenges to this front.

摘要： Recently,at an intellectual property dispute mediation seminar held by the CCPIT Mediation Center,a second batch of 10 experts appointed by the intellectual property professional committee was announced.These 10 experts are senior scholars,former judges and intellectual property experts with significant influence in the field of intellectual property in China and abroad.They have a lot of varied working experience and deep theoretical knowledge in the settlement of intellectual property disputes.Lu Pengqi,Deputy Chairman of the CCPIT and chairman of the CPPIT Mediation Center,said at the seminar that as a trade and investment promotion agency,the CCPIT has been attaching great importance to resolving intellectual property disputes through arbitration and mediation when connecting with government and enterprises.

摘要： Globalisation has encountered many obstacles in recent years.Trade protectionism,populism and other anti-globalisation trends are surging.The continued spread of COVID-19 has exacerbated the gap between countries and caused serious losses of life and property.The problem that the global governance lagging behind global practice becomes more prominent,and mankind is also facing a civilisation crisis.

摘要： The influence of PVA water soluble film on the quality of llaundry capsule was discussed from three aspects:appearance,manufacture and use.The basic properties of several mainstream PVA membranes on the market related to laundry capsules were evaluated.The results show that the mist value of the film affects the appearance of the capsules.The higher the mist value is,the worse the transparency of the capsules is.The mechanical properties of the film affect the shape of the capsules,the tensile strength>35 Mpa,elongation>400%,modulus>50 Mpa,the shape of the capsules is more three-dimensional;The water solubility of the film can affect the production of the capsules,and the production of the capsules is smooth when the film breaking speed is greater than 20~30 s and the dissolution speed is 40~60 s.The film compatibility index reflects the effect of the capsules washing machine.The shorter the dissolution time of the compatibility,the less the residue of the capsules after washing.

摘要： Objective:The application of Chinese materia medica(CMM)in clinical diseases is the embodiment and continuation of the property theory of CMM(PTCMM).However,due to a lack of precise quantitative description methods,it is difficult to systematically analyze the property of CMM(PCMM)and clinical effect features at the micro molecular level.Methods:The therapeutic drugs and targets were obtained from the Drugbank database.The molecular descriptors of these drugs were calculated based on Dragon software.Drug-effect relationships that integrated the molecular descriptors and effect descriptors were plotted as grayscale images.These images were used to train the Le Net-5 model and the Alex Net model.The best-performing model was used to predict the effect features of the CMM compounds.Finally,the effect features of the PCMM combinations were calculated based on the support vector machine recursive feature elimination algorithm.Results:The Alex Net model showed a superior prediction performance.The results showed that its accuracy,precision,sensitivity,F-measure,and Matthews correlation coefficient on the training set were 0.940,0.936,0.945,0.940,and 0.880,respectively,and those of the test set were 0.909,0.901,0.920,0.910,and 0.819,respectively.A total of 399 compounds in the 42 CMMs for promoting blood circulation and removing blood stasis were predicted by this model.The key effect features of the Han-Ku-Gan combination were anti-inflammatory,anti-tumor,anti-atherosclerosis,anti-Parkinson,hypoglycemic,and anti-coagulant properties,as well as excitation of uterine smooth muscle.The key effect features of the Wen-Xin-Gan combination were anti-inflammatory,anti-atherosclerosis,anti-hypertensive,anticoagulant,anti-tumor,and anti-cardiac insufficiency effects,as well as enhanced immunity,sedation and hypnosis,and analgesia.Conclusion:This study provides a new method for the further exploration of the relationship between the PCMM and clinical effect features.

摘要： 3D electrodes have shown extraordinary promise for electrochemical energy storage devices in wearable electronics.However,it is still a significant challenge to rationally design 3D electrode that has the characteristics of lightweight,flexibility,low cost,high performance and miniaturization.In this work,we present a novel design of 3D electrode by directly growing the nanocrystalline TiO_(2)film on carbonized eggshell membrane.The unique architecture can supply not only a continuous electron transport pathway through an interconnected carbon fibrous network but also an efficient electrolyte flux via an interpenetrating porous network.Besides,nanocrystalline TiO_(2)film on carbonized eggshell membrane offers a short ion diffusion path in the solid-phase,leading to a rapid kinetic of electrochemical reaction.When tested as an anode for Li-ion battery,TiO_(2)film in 3D electrode demonstrated excellent electrochemical performance with a large reversible capacity,excellent rate capacity and long life cycling property.
