Certainly one of the best spots in the Mediterranean , Barcelona is the capital city of Catalunya and is one of the 17 Autonomous Communities that make up Spain . It is strategically located in a very privileged position on the northeastern coast of the Iberian peninsula, along the Mediterranean coast, around 41 and 2 Its being located at the Mediterranean sea in the very north of the Spanish coast also contributes to making it certainly the most cosmopolitan and most economically active city in the country of Spain . Barcelona is 160 km (100 mi) south of the Pyrenees mountain range and is nestled in between the mouths of the rivers Llobregat and Bes , and the shores of the Mediterranean . It has an altitude of 4 m above sea level and has the following distances from: Tarragona (98 km), Girona (100 km), Lleida (156 km), Huesca (274 km), Castellon (284 km), Zaragoza (296 km) and Madrid (621 km).Located in the comarca of Barcelon , Barcelona is also the second largest city in Spain in both size and population. The city has a population of 1,510,000, but this number escalates to more than 4,000,000 if the outlying areas are also included in the count.

细菌检验方法：如果经营出口食品，那就必须遵守进口国的相关法律和标准，所以标准是否合理不能用我国的标准衡量，而要看是否符合进口国的标准，你最好向进口方索要相关的采样和检验方法，按照他们的标准做，免得误事。2、面积是指涂抹面积而不是培养基面积。3、检验结果出现小数是可能的，因为采样结果计算公式：细菌总数(cfu/cm2)＝ 平皿上菌落的平均数 × 稀释倍数/ 30×2举例：平皿上菌落数（10，9），结果为：9.5×10/60=1.6 (cfu/cm2)4、附手消毒效果检测方法：被检人五指并拢，用浸有含相应中和剂的无菌洗脱液的棉拭子在双手指屈面从指根到指端往返涂擦 2 次(一只手涂擦面积约 30cm2)，并随之转动采样棉拭子，剪去操作者手接触部位，将棉拭子投入 10ml 含相应中和剂的无菌洗脱液试管内，立即送检。细菌总数检测：将采样管在混匀器上振荡20s或用力振打 80 次，用无菌吸管吸取 1.0ml 待检样品接种于灭菌平皿，每一样本接种2个平皿，内加入已溶化的 45℃～48℃ 的营养琼脂15ml～18ml，边倾注边摇匀，待琼脂凝固，置 36℃±1℃温箱培养 48h，计数菌落数。

储氢材料是一类能可逆地吸收和释放氢气的材料。最早发现的是金属钯，1体积钯能溶解几百体积的氢气，但钯很贵，缺少实用价值。20世纪70年代以后，由于对氢能源的研究和开发日趋重要，首先要解决氢气的安全贮存和运输问题，储氢材料范围日益扩展至过渡金属的合金。如镧镍金属间化合物就具有可逆吸收和释放氢气的性质：每克镧镍合金能贮存0.157升氢气，略为加热，就可以使氢气重新释放出来。LaNi5是镍基合金，铁基合金可用作储氢材料的有TiFe，每克TiFe能吸收贮存0.18升氢气。其他还有镁基合金，如Mg2Cu、Mg2Ni等，都较便宜。储氢合金的应用方面很多，除了以上介绍的内容外，还在空调与制冷，热泵、热-压传感器、加氢和脱氢反应催化剂等方面都可得到应用。

目的建立用新型四唑氮盐MTS和XTT做比色分析测定淋巴细胞增殖效应的方法。方法分别用MTS、XTT结合PMS,对小鼠脾淋巴细胞密度和增殖进行比色测定,选择最佳实验条件,并将这两种方法与3H-TdR掺入法和MTT法比较。结果用MTS和XTT比色分析法测定小鼠脾淋巴细胞的增殖,在0.5～4×109/L的范围内,所获光吸收(A)值与细胞密度呈良好的相关性。最佳细胞密度为2×109/L,最佳反应时间为6h,最佳PMS的终浓度为1×10-4mol/L。两种比色法与3H-TdR掺入法的结果相一致,且两种新方法较MTT法灵敏。结论MTS和XTT比色分析法可代替3H-TdR掺入法和MTT法,用于测定淋巴细胞的增殖效应。免疫学研究中，测定淋巴细胞增殖常用的方法主要有3H－TdR掺入法和MTT比色分析法。经典的3H－TdR掺入法具有灵敏、可靠的优点，但操作繁琐，又存在着放射性污物的处理问题。MTT比色分析法较简便，但灵敏度较低，在测定过程中可产生不溶于水的结晶产物，需要溶解后才能测定
