胶黏剂作为一种新型的连接材料在国民经济的各个领域应用越来越广泛。胶黏剂的剪切强度与黏接过程中形成的化学键等作用力以及胶黏剂本身的结构有关,同时还与胶接材料表面状况、胶接工艺等因素有密切联系。主要研究了胶接材料的表面处理方法、漂洗水温、胶层厚度、胶液稳定性等因素对胶黏剂剪切强度的影响。 相似文献

<正> 以彩印复合塑料薄膜包装各种食品,目下非常风行。它们中有一般的复合薄膜袋垫封口包装,有装填食品后于真空包装机中抽真空后自动封口的真空包装。至于某些含汤食品在真空包装后再经杀菌工序者,它与普通罐头一样,也可以室温保存,即成为所谓“软罐头”了。 上述各类软包装的共同点,就是应用各种塑料薄膜作为包装材料,而它是高分子化学物质的产物,一般从业人员,食品加工销售人员对这类包装材料的性能是比较陌生的,所以有必要 相似文献

Recently, concerns have been rising that the energy transition may impair the security of power supply in Germany by increasing the risk of shortages and black-outs in the long run. While power generation from volatile wind and solar energy has grown rapidly, incentives to invest in conventional back-up capacity have diminished. To respond to these concerns, the German government has adopted an energy policy reform package to strengthen the regulatory framework for the power market. But is this package appropriate to sustainably safeguard the German power supply? 相似文献

This paper examines short‐run information transmission between the U.S. and U.K. markets using the S&P 500 and FTSE 100 index futures. Ultrahighfrequency futures data are employed—which have a number of advantages over the low‐frequency spot data commonly used in previous studies—in establishing that volatility spillovers are in fact bidirectional. The generalized autoregressive conditionally heteroskedastic model (GARCH) is employed to estimate the mean and volatility spillovers of intraday returns. A Fourier flexible function is utilized to filter the intradaily periodic patterns that induce serial correlation in return volatility. It was found that estimates of volatility persistence and speed of information transmission are seriously affected by intradaily periodicity. The bias in parameter estimation is removed by filtering out the intradaily periodic component of the transaction data. Contrary to previous findings, there is evidence of spillovers in volatility between the U.S. and U.K. markets. Results indicate that the volatility of the U.S. market is affected by the most recent volatility surprise in the U.K. market. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:553–585, 2005 相似文献

The European Employment Strategy is the subject of controversial discussion. It is hard to find an economic justification for transnational responsibility since European labour markets are heterogenous and spillover effects of national employment policies are almost negligible. In its latest communication, the European Commission fails to provide a masterplan for a recovery of the struggling labour markets, although it provides convincing and less convincing proposals for tackling unemployment in EU member states. There is a suspicion that the package mainly serves as a first step towards transferring employment policy responsibilities from the national to the EU level. But the EU labour market policy lacks appropriate instruments and competences. Finally, it is questionable whether the package fits in an economic growth plan. 相似文献

Packaging has emerged as an important competitive tool. An innovative package can pre-empt a market position, create a new market and lead to greater sales and profits, just as an improved or reformulated product can. This report investigates the adoption process for packaging innovations in food and food-related items. It seeks to answer certain questions pertaining to the adoption process: Do early adopters differ from the general population? What factors serve to accelerate the rate of adoption of packing innovations by consumers? What kinds of packinging innovations become successes? The results of a small-scale empirical study comparing early adopters of packaging innovations with the general populations provide some answers to these questions. The report concludes with recommendations to management for successful innovative packaging. 相似文献

This paper raises doubts about the proposition that monetary policy is effective, under flexible exchange rates, in stabilizing domestic output. It is argued that if the price elasticities of the demands for exports and imports are affected by the transition to flexible rates, and capital flows are assumed to be dependent on the exchange rate, the efficacy of monetary policy under flexible rates will not necessarily follow. 相似文献
