Obviously, the optimization management in middle-sized or small cities of China is very necessary. The basic characteristics of municipal solid waste generated in middle-sized or small cities of China are put forward in the paper. The total amount of municipal solid waste generated in middle-sized or small cities is significantly less than that in large cities. The amount of garbage is about 1 kg per capita and year. In the garbage, inorganic material is more than organic material, the combustible less than incombustible and the amount of uncompostable garbage more than the amount of garbage that can be disposed for composting. The value of heat of garbage is about 800 kal/kg.

通过总结，我国中小城市生活垃圾的基本特点为：各城市的生活垃圾产生量相对较小，人均生活垃圾产生量大约在1kg/d左右；垃圾组分中以煤渣、灰土为主的无机成分含量过高，可回收物质成分含量很低，不可燃成分多于可燃成分，不可堆腐成分多于可堆腐成分，垃圾热值大约在800kal/kg左右；并且在我国，南方城市与北方城市，经济发达城市与欠发达城市之间的生活垃圾产生量与组成也存在着明显的地区差异。

The experimental results showed that using ionic liquid Et3NHCl-2AlCl3 under the conditions of an extraction temperature of 40℃, an extraction time of 40 min and an agent/oil ratio of 0.02, the sulfur removal rate was more than 90%. The ionic liquids could be used repeatedly for 4 times and the used ionic liquids could be regenerated by vacuum distillation, about 52.34% of the thiophen was recovered during regeneration.

实验结果表明，选用无水AlCl3与Et3NHCl的摩尔比为2.0的离子液体进行萃取脱硫实验，当萃取时间为40 min、温度为40 ℃、剂油体积比为0.02时，脱硫率可达到90%以上；离子液体不仅可以重复使用4次，而且还可以通过减压蒸馏的方法进行再生，在再生过程中可回收约52.34%的噻吩。

The product was immiscible with catalyst/water and could be separated simply by filtration after the reaction. This method is manipulatively simple, environment-friendly and the catalyst is reusable.

反应生成的取代氢化氧杂蒽与离子液体的水溶液不相溶，通过简单的过滤可实现产物与催化体系的分离，简化了分离过程，方法操作简便、环境友好、催化剂可回收并重复使用。

Nomatter from the choice of sustainable and recycledmaterials, the changes in size and space, orthe protection of the natural resource and it**ploration, we can be aware of bio-diversified,sustainable development, ecological environmentconcept around every corner of our life.

无论是环保、可回收材料的使用，尺度空间的变化，还是自然资源的保护和合理开发利用，我们都能切身地体会到生物多样性、可持续发展和环境生态理念一直伴随其左右。

Primary culture of goat mammary gland cells could be derived by outgrowth of migrating cells from fragment of tissue. Fibroblast and epithelial cells could be pured according to their different sensibility to trypsin. Complex cultures treated by 0.25% trypsin in Hanks' for 5~7min at 37℃, the dispersed cells were mainly fibroblasts,then the rest treated by 0.15% trypsin-0.02% EDTA in Hanks'for 5~8min at 37℃, the majority cells harvested were mammary epithelial cells.

用组织块培养法可获得良好的山羊乳腺细胞原代培养物；培养的山羊乳腺成纤维细胞比上皮细胞对胰蛋白酶更敏感，据此可在传代过程中将二者分离纯化，获得纯细胞系；混合培养物先用0.25%胰蛋白酶在37℃消化5~7min 所收集的细胞主要为成纤维细胞；再加0.15%胰蛋白酶-0.02鞹A 消化液在37℃继续消化5~6min 所回收的细胞绝大多数为上皮细胞，经过2~3 代，即可得到纯化的乳腺上皮细胞系。
