废润滑油的再生利用

我厂有各类压缩机、泵几百台。每天各机泵排入地沟中的废油有三四桶，约５００～６００公斤。若对此不再生利用，不但污染环境，对企业也是一项很大浪费。多年来我们一直在探索废油的再生处理重新使用的技术。开始时我们只能对曲轴箱、油箱中放出的废油进行处理，进而对排...     

浅述粉煤灰在废润滑油再生中的应用

粉煤灰干灰代替其它多种吸附剂，对于不同标号的废润滑油（以下简称“废油”）再生时加入不同量的粉煤灰后，效果都非常显著。它不但能大幅度地降低生产成本与劳动强度，同时使再生油的重要指标都有所提高。粉煤灰对大量废油的再生利用，达到以废治废，一举多得，效果显著，推广前景广阔。１生产工艺工艺流程：废油→粗滤→细滤→加温→搅拌→加粉煤灰→沉降→脱水、排污→精滤→成品。２操作工艺说明由于润滑油的使用条件不同，废油中所含杂质的种类和数量也不同。因此，对不同品种的润滑油要用不同的再生工艺，对不同的杂质要用不同的方法…     

一汽废油再生利用工作纪实

在中国第一汽车集团公司，每天有上万台各类设备投人生产运行。这些种类繁多的设备，需要各种润滑油和冷却液来维护保养。据统计，以年产10万辆汽车计算．一汽每年设备用油需2000吨以上产生的废油每年多达1300吨。这些废油以前回收利用率较低，大部分被作为废弃物排放掉，给环境带来一定污染。“七五”初期，一汽汽车产品换型改造成功，一大批经过技术改造和引进的设备形成了新的生产能力。使得生产设备保养用油量加大；每天有大量的废油白白流掉。为使这些废油得以再生，1987年7月，一汽成立了附属职业高中润滑油实习工厂（现更名为一汽四…

从槐米中提取芦丁的研究

通过实验对从槐米中提取芦丁的工艺进行了研究，得到了较佳的提取工艺条件：槐米粉碎，加入5倍量的水，用石灰水调pH值至8－9，加入3％的硼砂，抽滤。反复提取3次。滤液用稀盐酸调pH值至2－3，静置6h，析出沉淀，过滤，滤渣干燥，即得粗芦丁。将粗芦丁进行精制可得精制芦丁，纯度可达99％以上。     

废油再生利用——解决润滑基础油短缺的一个重要途径

后世界经济危机时代,各国必然要进行大规模产业结构调整和产品升级,都离不开对润滑油的大量需求。国内中石油、中石化、中海油3大基础油生产企业其产量远远满足不了市场需要,这就为废油再生和解决基础油短缺提供了一条重要途径。

日本的地沟油流向了哪里？

所谓地沟油，是从居民下水道生活污水中捞取漂浮的废油，经过加工过滤而得。若用于食用，不但心理上让人难以接受，而且带有大量毒素和致癌物质，对人体伤害极大。既然地沟油来自生活污水，中国有地沟油，日本当然也有。在日本的食品问题上似乎从未见到关于地沟油的报道，

Penetration and Post-infection Development of Meloidogyne Incognita on Tobacco as Treated by Rhizobacteria Pseudomonas Fluorescens Strain P-72-10

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.     

The causes of Japan's ‘lost decade’: The role of household consumption

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.

城市社会的开放与农民的城市化

城市社会在对农民的开放与封闭之中徘徊。改革开放后城市社会对农民的开放已经使很多农民城市化。城市社会对农民的封闭已由政策性封闭转向经济性封闭。城市社会对农民的封闭增加了农民城市化的成本和社会风险。必须加强城市社会对农民的开放,逐步消除对农民的封闭政策,以推进农民的城市化。
