A Smart Dog     
A Smart Dog Wilkins was hot and tired, so he went into a small cafe(咖啡馆) for a cold drink. The place was empty except for an old man and a dog. They were both sitting at a table in a corner of the cafe. In front of them was a chessboard. For a moment, …  相似文献

This study was aimed at investigating the sampling strategies for 2 types of figures: 3-D cubes and human faces. The research was focused on: (a) from where the sampling process started; (b) in what order the figures' features were sampled. The study consisted of 2 experiments: (a) sampling strategies for 3-D cubes; (b) sampling strategies for human faces. The results showed that: (a), for 3-D cubes, the first sampling was mostly located at the outline parts, rarely at the center part; while for human faces, the first sampling was mostly located at the hair and outline parts, rarely at the mouth or cheek parts, in most cases, the first sampling-position had no significant effects on cognitive performance and that (b), the sampling order, both for 3-D cubes and for human faces, was determined by the degree of difference among the sampled-features.  相似文献

美式烹饪     
At a local supermarket, two women push half-filled grocery carts. The ladies are good friends, but they couldn't be more different. One is a stay-at-home housewife who loves to create culinary masterpieces from scratch. The other is a training supervisor at a prestigious advertising agency. Household chores, particularly those in the kitchen, are not her idea of fun. The two ladies stop for a moment in the frozen foods section. "I'm so tired," sighs the professional woman. "I don't know what to do about supper." Her friend suggests, "What about a microwave dinner?" The weary professional sighs, "No, I don't feel like cooking tonight."  相似文献

The influence of the physical structure of polyurethane matrix as a support in a solid state culture in tannase production and gallic acid accumulation by Aspergillus niger Aa-20 was evaluated. Three different polyurethane matrices were used as the support: continuous, semi-discontinuous and discontinuous. The highest tannase production at 2479.59 U/L during the first 12 h of culture was obtained using the discontinuous matrix. The gallic acid was accumulated at 7.64 g/L at the discontinuous matrix. The results show that the discontinuous matrix of polyurethane is better for tannase production and gallic acid accumulation in a solid state culture bioprocess than the continuous and semi-discontinuous matrices.  相似文献

Both Debbie and Simon work in the Sunbeam Travel Company. One day they were sitting in the office. The door opened and a lady entered. She looked quickly at them both, paused a moment, then walked over and sat opposite Debbie. Debbie greeted her cheerfully, and they got down to business. "Can you...?"  相似文献

Humour Page     
Passsge 1:It was one of those days in the Wild West. A rugged cowboy with a horrible scar on his face and a shiny gun at his belt rode very slowly into a dusty town as if he was a dead man. He left his horse outside the bar and stepped inside. The bar was full of people. They all gave the stranger a look in a brief moment of silence before they went back to their own drinking and laughing. The stranger ordered a glass of cold beer, gulped it down and walked out slowly-only to find his horse missing.  相似文献

I once stayed at St Paul's Grammar School in Sydney, Australia, as a visiting teacher for two months. From the moment I got there till the time I left, I seldom felt lonely and homesick. I know that's because Australian people are friendly to us and willing to help us. My friend Patsy Beckett is one of them.Patsy, (Mrs. Beckett) is the Principal's Personal Assistant at the school. Though she is busy all the time, she has arranged my visit in great detail. The first day I came to school she took me to my homestay's house herself, and there I found some beautiful flowers and nice fruit on the desk in my room. I thought this was a nice gesture of friendship.  相似文献

Supersaturated solid solutions Fe1-xCx (0≤x≤0.9 ) of wide composition range have been prepared by mechanical alloying process. Nanocrystalline phase was formed for 0 ≤ x ≤ 0.67 and a large grain phase for 0.75 ≤ x ≤ 0.9. The large fraction of graphite volume puts off formation of nanocrystalline phase for high carbon content. In the large grain phase, magnetization follows simple magnetic dilution, and eoereivity He is mainly due to dissolution of carbon at grain boundaries. In the nanocrystalline phase the alloying effect of carbon is revealed by a distinct reduction of average magnetic moment. The increasing lattice constant with increasing carbon content is observed for x ≤ 0.5, suggesting that the high carbon concentration may enhance diffusion of carbon into the Fe lattice. It shows a discontinuity in the Hc variation with a grain size D of nanocrystalline phase. For small grain D below the critical value, Hc increases with D. For a large grain D, Hc decreases with increasing D. The solubility limit of carbon in a-Fe extended by nanocry- stalline phase formation is discussed.  相似文献
