2010年前我国城市燃气以天然气和液化石油气(LPG)为主,2010年以后,城市燃气逐步过渡到天然气为主导气源的时代。目前,国内的天然气供应仍显不足,液化石油气依托天然气管网资源,依托较为成熟的LPG混空气工艺,依然具有再利用价值。本文首先阐述了液化石油气与天然气的组成及物理性质,然后分析了液化石油气与天然气市场应用现状,最后分别论证了液化石油气与天然气互换的技术可行性、液化石油气基础设施再利用的可行性。 相似文献

随着改革开放的深入,我国各地相继建立了许多大大小小的液化石油气站,使既方便又卫生的液化石油气代替了原始的柴和煤。但由于气站设计时没有考虑到分离器正常排液的回收,因此造成了浪费,污染环境和存在不安全因素。现就液化石油气回收方法分别进行介绍,以供同行们参考与借鉴。1从分离器内回收液化石油气在装卸槽车、正压抽残液或灌装钢瓶等作业时要启动液化石油气循环压缩机,在它的前面安有两台分离器,目的是将系统内一部分气体因温度和压力变化而变为液体时在分离器内被分离而滞留在分离器的底部,防止液体进入循环压缩机内损坏设… 相似文献

26个“火人”推出着火的液化气货车1964年1月3日下午1时50分,“嘭”的一声巨响,锦州市汽车站第六维修车间里的一只气罐裂开了一道长长的口子,里面的气体喷射出来。大货车后部的液化石油气体要爆炸了!车间里的人们都被吓坏了。几天前,第六维修车间里开进了一辆待修的“解放”牌大货车,里面本该容纳90公斤液化石油气的气罐却装了100多公斤的液化石油气。 相似文献

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. 相似文献

This paper quantifies the local impacts of mechanized logging on forest-dependent communities in Indonesia, before and after decentralization. A conceptual framework incorporates financial, social, enforcement, rent-seeking, and environmental impacts. Using data from 60 communities in East Kalimantan, the empirical results suggest that significantly more households received financial and in-kind benefits after decentralization compared to before. Many communities engaged in self-enforcement activities against firms both before and after decentralization. Post-decentralization, a significantly higher proportion of households perceived community forest ownership. There were few significant differences in perceived environmental impacts. Little evidence exists of a post-decentralization trade-off between environmental and financial contractual provisions. 相似文献

Zusammenfassung Die vorliegende Studie analysiert für 87 Neuprodukteinführungen (NPE) und Auslandsmarkteintritte
(AME) von Telekommunikations(TK)-Diensteanbietern in Deutschland, zu denen 42 Schlüsselinformanten
in einer schriftlichen Befragung Auskunft gaben, (1) inwieweit deren zeitliche Eintrittspositionierung durch
Marktcharakteristika und Unternehmensressourcen erkl?rbar ist sowie (2) inwieweit und gegebenenfalls
unter welchen unternehmensexternen und -internen Situationsbedingungen deren Markteintrittstiming mit dem
wahrgenommenen Eintrittserfolg assoziiert ist. Ein früher Markteintritt wurde dann realisiert, wenn
die Wettbewerbsintensit?t im adressierten Gesch?ft niedrig und das Budget für den Expansionsschritt
überdurchschnittlich ausfielen. Zwischen dem Markteintrittstiming und der Beurteilung des Eintrittserfolgs
bestand ein nicht monotoner, umgekehrt U-f?rmiger Zusammenhang: Frühe Folger wiesen signifikant
bessere Erfolgswerte auf als Pioniere und sp?te Folger, deren Erfolgsniveaus nicht signifikant divergierten.
In einer Industrie, die durch starke externe Netzeffekte gepr?gt ist, fallen offenbar die Nachteile
eines Markteintritts als Pionier oder sp?ter Folger st?rker ins Gewicht als die Vorteile dieser
beiden zeitlichen Eintrittspositionierungen. Unabh?ngig vom Markteintrittstiming wurden NPE/AME von
TK-Unternehmen als erfolgreicher eingestuft, wenn sie sich in einen Markt mit stark wachsender Nachfrage
und aufeinander abgestimmt (re)agierenden Wettbewerbern mit qualitativ überdurchschnittlichen, abw?rtskompatiblen,
erprobbaren und wenig erkl?rungsbedürftigen TK-Diensten engagierten.

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. 相似文献

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. 相似文献
