钻表的意义

关于在手表上镶钻是否有意义，我想反问一句：在高级汽车内，选用珍稀木料以及各种昂贵皮料制作内饰是否有意义？奢侈品之所以被称作奢侈品，是因为它所反映的绝不是某种孤立的奢侈元素的单一体现，而是融材质、技艺、文化、思想为一身... 详细信息

关于在手表上镶钻是否有意义，我想反问一句：在高级汽车内，选用珍稀木料以及各种昂贵皮料制作内饰是否有意义？奢侈品之所以被称作奢侈品，是因为它所反映的绝不是某种孤立的奢侈元素的单一体现，而是融材质、技艺、文化、思想为一身的集中体现，唯有它们相辅相成孕育出的成果，才最能符合稀缺性的特征，这就是奢侈品的定义，当然也是镶钻手表的意义。

Plant take up the essential nutrient sulfur as sulfate from the soil, reduce it, and assimilate into bioorganic compounds, with cysteine being the first product. Both sulfate uptake and assimilation are highly regulated by the demand for the reduced sulfur, by availability of nutrients, and by environmental conditions. In the last decade, great prog- ress has been achieved in dissecting the regulation of sulfur metabolism. Sulfate uptake and reduction of activated sulfate, adenosine 5＇-phosphosulfate （APS）, to sulfite by APS reductase appear to be the key regulatory steps. Here, we review the current knowledge on regulation of these processes, with special attention given to similarities and differences.

The chemical communication system in Drosophila melanogaster Meigen,1830 plays a major role in courtship and consists of the male-specific cis-Vaccenyl acetate and sex-specific contact pheromones,cuticular hydrocarbons(CHC),which build up during ontogeny(first 4 days).They replace longer CHCs,common to both sexes and present only after the imaginal eclosion.A detailed quantitative description of the evolution of cuticular unsaturated hydrocarbons with age is presented here for males and females of different *** strains,which have been bred in well controlled *** appear in both sexes at around 12 h,before female *** present paper argues that this is likely linked to the switching on of a new set of ***,which is more abundant in females than in males during this critical period,might control this *** behavioral studies show that whereas female of all ages trigger early mature male courtship steps like wing vibration,only females older than 1 day trigger late courtship steps like attempted *** supports the hypothesis that late male courtship steps might be triggered by the CHCs,which build up after this age,especially female-specific(Z,Z)-7,11-and(Z,Z)-5,9-dienes.

We present a novel grid-based method for simulating multiple unmixable fluids moving and interacting. Unlike previous methods that can only represent the interface between two fluids （usually between liquid and gas）, this method can handle an arbitrary number of fluids through multiple independent level sets coupled with a constrain condition. To capture the fluid surface more accurately, we extend the particle level set method to a multi-fluid version. It shares the advantages of the particle level set method, and has the ability to track the interfaces of multiple fluids. To handle the dynamic behavior of different fluids existing together, we use a multiphase fluid formulation based on a smooth weight function.
