How could we have a effective teaching?We,as teachers,always think about this question and always hope to have better experiences to supple- ment us.The art of teaching lies in the teaching of the teacher and the studying of the students.During this course, a teacher's quality will be re- garded as an important factor in the art of teaching which we have to think over and discuss.Of course,the factors of students will be undoubtedly tak- en into consideration because of their significance.HereⅠwould like to sunmaarize the following points to improve our teaching effect. 相似文献

How did the Yellow River develop and evolve? Whendid it form? The geoscientists have concerned these im-portant questions for a long time. They have done a lot ofresearches on these issues and gotten a lot of valuableresults, while there are still many controversies. In general,it mainly includes several points as follows. According tothe transition of the fluviolacustrine strata, biological fos-sils and geologic structure in Lanzhou and Yinchuan, Linmade a conclusion that the Yellow River… 相似文献

Hyperbranched polymers have been paid attention because of their unique structures. Especially, they have many terminals whose number is the same as that of repeating units as far as they are synthesized from AB2 type monomers. These characteristics of the hyperbranched polymers make them new functionalized polymers. Polysiloxanes have unique properties such as low Tg, high decomposition temperature, water repulsion, and good dielectric property. They are widely fabricated from liquid (oil) to solid (resin) by changing the extent of crosslinking. We have studied dendrimers and hyperbrached polymers possessing polysiloxane structure. These materials have the amphiphilic nature when they have amine functional group at the terminal position. 相似文献

The dye-sensitized nanocrystalline TiO2 thin filmsolar cells (DSSCs) have attracted much attention since1990s[1— , due to their high light to electrical energy 4]conversion efficiency. So far, many studies have beenmade on the use of liquid electrolytes such as acetonitrile,3-methoxypropionitrile and a mixture of ethylene/pro-pylene carbonate (EC/PC) containing I? /I3 redox cou-?ple. A light to electrical energy conversion efficiency of7%— 12% has been obtained for DSSC using liquid e… 相似文献

The properties of the warp knitted spacer fabrics for pressure reduction are experimentally investigated and compared to other materials.The influences of the different parameters, such as thickness, spacer yarn diameter and connecting form are also analyzed and discussed. The results have shown that the spacer fabrics have very good properties for pressure reduction when they are used as soles, mattress or cushions. 相似文献

A series of simulations by mathematical and physical modeling on fluid flow, mass and heat transfer in continuous casting tundishes have been carried out. It was found by computational fluid dynamics (CFD) simulation that in most cases tundish flow must be treated as a non-isothermal reactor due to the existence of temperature difference between the transport ladle and the tundish.The critical conditions when the non-isothermal flow in the tundish can not be neglected have been found by CFD simulation and water modeling. A direct measurement in a 40 t tundish has confirmed the simulation results. 相似文献

In academic field,silence is classified as part of the nonverbal communication.Edward T.Hall regarded silence as a key standard of dividing high-context cultures and low-context cultures(毕 46).In high-context cultures,information is provided through gestures,the use of space,and even silence.Little information is explicitly explained by words.Chinese,Japanese,Native American cultures are high-context ones.However,"in low-context cultures,the verbal message contains most of the information and very little is embedded in the context."(Samovar,A.Larry,Richard E.Porter and Lisa A.Stefani 79).How do people from different cultures respond to silence? How their values affect their attitudes? What causes silence? 相似文献

Symmetric and asymmetric derivatives of thiocarbohydrazide have broadly been studied due to their potential utility as analytical reagents. Symmetric Schiff base can be easily obtained by direct reaction.while there have many troubles in obtaining asymmetric Schiff base. The obvious difficulty in the synthesis of asymmetric Schiff base is that the straight condensation methodology used for symmetric Schiffbase is no longer applicable when some symmetric dia mines were adopted as the parent reactants in the condensation reaction. As ketone has lower chemical activities than that of the aldehyde, 相似文献

Let K be an algebraic number field, k be a subfield of k. E. Artin and A. Frohlich asked and studied this question: when does K/k have a relative integral basis? i. e., when is the ring O_K, integers of K, a free O_k-module? In the case that K is a C_2~2 field, i. e. a bicyclic biquadratic field, this problem was studied in many papers and, finally, solved by L. C. Washington, R. H. 相似文献

We have investigated the influence of Ag nanorod radius(r)on the resonant modes of a two-dimensional plasmonic photonic crystal(PPC)with dipole sources embedded into the central vacancy area,using finite-difference time-domain methods.Both the localized surface plasmon(LSP)mode of individual Ag nanorods and the resonant cavity mode of PPC are found to vary as a function of r.The resonant cavity mode is strongly enhanced as r is increased,while the LSP signal will eventually become no longer discernable in the Fourier spectrum of the time-evolved field.An optimized condition for the nanocavity field enhancement is found for a given PPC periodicity(e.g.d=375 nm)with the critical nanorod radius rc=d/3.At this point the resonant cavity mode has the strongest field enhancement,best field confinement and largest Q-factor.We attribute this to competition between the blocking of cavity confined light to radiate out when the cavity resonant frequency falls inside the opened photonic stopband as r reaches rc,and the transfer of cavity mode energy to inter-particle plasmons when r is further increased. 相似文献

T4T-dimethyl is commonly employed as hard segment when polyesteramide is produced. Polyesteramide is one of thermoplastic elastomers, like polyurethane which is composed of two different types of segments, usually referred to as soft and hard segments. The characters of hard segment have much influence on the properties of the polymer. To get the polyesteramide with high order, it is desirable to make T4T-dimethyl pure. In this paper, how to synthesize, to purify as well as to detect the purity of T4T-dimethyl are described in detail. 相似文献

Journalist(J):As a young and local man, you are appointedas the General Manager of Micron Electronics Inc.China,how doyou think about this?Zhang:Now we find Intel,IBM and other US companiesbegan to localize their high-level of management team in China andthis is the right way to manage company here and do business.And the local managers'devotion,understanding the local culture,making right decision of investment for both their companies andChina should be emphasized. We should not deny Motorola,IBMand other companies had trained many local manager talents.Somehigh-level managers in Compaq,Ericsson and Microsoft are fromIBM.I used to work for IBM also.It is a great challenge to work in these global companies.Iwas very dedicated when I was working for IBM and paid moreattention than others.I often kept an eye on what the other depart-ments do after I had done my own job.After fifty years of estab-lishment of the new China,we have some big enterprises such asHaler and Legend,but in comparison with Coca-Cola and IBM, 相似文献
