Youth is not a time of life; it is a state of mind; it is not a matter of rosycheeks, red lips and supple(柔韧的)knees; it is a matter of will, a quality of imagination, a vigor of the emotions; it is the freshness of the deep springs of life.Youth means a temperamental predominance(支配,主导)of courage over timidity(胆怯),of the appetite for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of 相似文献

Not long ago, a series of new images for the major characters in the film Journey to the West(《西游记》) designed by Zhang Jizhong(张纪中)was made known to the public. According to Mr. Zhang, Sun Wukong (孙悟空) would appear in the form of a human being instead of a monkey; Tang Seng (唐僧) would look like a masculine man instead of a handsome young man; and Zhu Bajie(猪八戒)would be a wild boar (野猪) instead of a domestic pig. Such images, which are totally different from the traditional ones, have caused a great shock. 相似文献

Pearls are formed naturally inside oysters(牡蛎) .But only one oyster in a thousand produces a pearl large enough to be a precious jewel.Oysters produce pearls to protect themselves. Sometimes a tiny piece of sand gets inside an oyster's shell (壳) .It could harm the soft flesh of the oyster.So the oyster covers the piece of sand with a layer (层) of smooth shell material .Each year new layers are added,and the pearl gets bigger. 相似文献

The influence of solvent (in its gaseous state) on the stability of crystallized organic compounds was investigated. Through two examples of studies on the solid/vapour equilibria made in our lab, several behaviors were highlighted: (i) a new hydrated phase (thermodynamically stable) of an active pharmaceutical ingredient (API) was detected after the recrystallization starting from a deliquescent state, (ii) a spontaneous resolution of a hydrated racemic compound towards an anhydrous conglomerate can occur during the desolvation under the precise conditions of temperature and humidity. This study illustrates that knowledge about solid/vapour equilibrium is a crucial step during the complete characterization of solid organic compounds. 相似文献

A Vision of 3D Factory
3D工厂真实写照
Inside a Iow-rise building in a business park at Rock Hill,South Carolina,is a vision of the factory of the future.Several dozen machines are humming(发出嗡嗡声),monitored from a glass-fronted control room by two people looking at computer screens.Some of the machines are the size of a car,others that ofa microwave oven(微波炉),but they all have windows that you can peer into.One is making jewellery,others are producing the plastic grip(塑料夹子)for an electric drill(电钻),the dashboard(仪表盘)of a car,an intricate lampshade(灯罩)and a bespoke(定做的)artificial leg.One is even making parts to build more machines like itself. 相似文献

INTRODUCTION An important problem in foundation engineeringis the determination of the rate of settlement of a raftfoundation placed on a deep clay layer. Gibson andMcNamee (1957), and McNamee and Gibson (1960a;1960b) considered the problem of normal uniformloading applied to the surface of a half-space andshowed that one-dimensional theory gives a markedunderestimate of the rate of settlement. This theorycorresponds to the case of a perfectly flexible footing.However, it is often… 相似文献

<正> A t-(v,k,λ)design(X,B)is a set X of points,of cardinality v,and a collection B of k-subsets of X called blocks,with the property that every t-subset of X is contained in precisely λ blocks.A t-design is a t-(v,k,λ) design for some v,k,γ.In this paper,we give a generalization of t-design called balanced n-ary t-design,and obtain some properties of the new combinatorial structure. 相似文献

INTRODUCTION Bangla language is characterized by a rich sys-tem of inflections(VIBHAKTI),derivation,and compound formation(Saha et al.,2004;Dash,1994;Chakroborty,2003),which is why the NLE using Bangla(output generation)is a very challenging task.Natural Language Engineering(NLE)is the process of computer analysis of input provided in a human language(natural language)and conversion of this input into a useful form of representation.The input of an NLP system can be:written text … 相似文献

This paper introduces a family of error-correcting codes called zigzag codes.A zigzag code is described by a highly structured zigzag graph.Due to the structureal properties of the graph,very low-complexity soft-in,soft-out decoding rules can be implemented.we present a decoding rule,absed on the Max-Log-APP(MLA) formulation,which requires a total of only 20 addition-equivalent-operations per information bit per iteration.Simulation of a rate-1/2 concatenated zigzag code with four constitutent encoders with interlezer length 65536 yields a bit error rate(BER) and of 10^-5 at 0.9 dB and 1.4dB away from the Shannon limit by optimal (APP) and low-cost sub-optimal(MLA) decoders,respectively. 相似文献

This paper presents a method of forecasting stable operation of gas compressor unit (GCU) centrifugal supercharger (CFS) installed on a piping of compressor shops servicing gas pipelines. The stability of superchargers operation is assessed in relation to the phenomenon of surge. Solution of this problem amounts to the development and numerical analysis of a set of ordinary differential equations. The set describes transmission of gas through a compressor shop as a fluid dynamics model with lumped parameters. The proposed method is oriented to wide application by specialists working in the gas industry. The practical application of this method can use all-purpose programming and mathematical software available to specialists of gas companies. 相似文献

Lipoic acid (LA) has received great attention in the area of gold surface functionalization. In this study, LA was employed as a linker for the attachment of antibody to the gold surface of surface plasmon resonance (SPR) chip. By using this chip in a homemade SPR immunosensor, low molecular weight compound 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) can be detected at a low level of 0.01 ng/mL. There is a good linear relationship(R2 =0.943 1) between the results of SPR biosensor and enzyme-linked immunosorbent assay(ELISA). 相似文献

Using degenerate primers and RT-PCR,RACE techniques,a 1491 bp cDNA segment of stearoyl-acyl carrier protein desaturase(SAD)is cloned from developing seeds of Jatropha curcas L.The segment contains a 1191 bp of complete open reading frame(ORF).Analysis in the BLAST on NCB! shows that Jatropha curcas SAD(JSAD)gene encodes a protein precursor composed of a signal peptide of 33 amino acids and a mature peptide of 363 amino acids.The homological analysis shows that JSAD has high level of homology both in nucleotide sequence and in amino acid sequence to other plants SADs.The nucleotide and peptide identity of JSAD to Ricinus communis SAD(RSAD)is up to 89% and 96.2% respectively.Molecular modeling of JSAD indicates that its three-dimensional structure strongly resembled the crystal structure of RSAD. 相似文献
