进入2005年以来,国家进一步加强和改善宏观调控,积极推进改革开放,GDP同比增长9.9 %,略低于2004年10.1 %的增长速度,国民经济呈现出增长较快、效益较好、价格平稳、活力增强的良好发展态势,包括纯碱行业在内的各行业继续保持了较快的发展.在此,笔者试图对2005年国内的纯碱市场进行分析并对2006年国内纯碱市场的发展趋势做出预测. 相似文献

2007年以来,我国经济呈加快增长趋势,汽车、轮胎工业等主要下游行业发展迅速,橡胶消费需求较为旺盛。但由于天然橡胶生产形势良好,产量增长加快,市场新增资源保持了较快增长,市场总体供需关系由去年的偏紧转向略有宽松。受此影响,市场价格较去年有所回落。虽然价位回落,但由于具有需求和成本支撑,整体价位依然是历史上的较高水平。合成橡胶价格受原油价格强劲攀升所带动,综合价格水平较去年小幅上涨。 相似文献

尽管行业低迷、效益转差,但行业投资仍保持较快增长,2013年中国国内芳烃聚酯供应快速增长,需求增长跌至低速水平,产能过剩苗头凸显,价格及毛利大幅下跌。预计2014年国内外宏观经济略有好转,需求转为正常增长,但行业过剩状况依旧;与此同时,芳烃供应的快速增长对于缓解原料供应紧张的局面起到重要作用,下游行业效益将改善。 相似文献

一、我国医药工业总体增长较快
2007年1~9月份,我国医药工业累计完成工业生产总值4458.91亿元(现价,九大子行业),比去年同期增长25.21%,增幅与2006年同期相比提高了6.19个百分点。这个数字是近10年来的一个高位,由于2006年同期的医药经济增长出现了近五年来较大的滑坡,基数相对较低,故继年中经济形势复苏后,医药工业生产总值出现了一个较快的增长。 相似文献

为掌握佛山市顺德新城区降水中污染物的情况,2015年7月至8月,文章作者分别在雨天进行了降水取样,对降水中的pH、电导率、常见阴离子(F-、Cl~-、NO_3~(2-)、SO_4~(2-))及部分重金属(铅和镉)进行监测分析。选择有相关数据的珠江三角洲和石家庄、厦门等地的降水中污染物的情况进行对比。结果表明,顺德新城区降水中的p H和部分阴离子浓度优于珠江三角洲平均值,酸雨类型属于硫酸和硝酸混合型;其水体洁净程度略差于石家庄;铅和镉的浓度也高于厦门,甚至部分超出了人体能直接接触的安全范围。 相似文献

Saturated very long chain fatty acids (fatty acids with greater than 22 carbon atoms; VLCFA) accumulate in peroxisomal disorders,
but there is little information on their turnover in patients. To determine the suitability of using stable isotope-labeled
VLCFA in patients with these disorders, the metabolism of 22-methyl[23,23,23-2H3]tricosanoic (iso-lignoceric) acid was studied in rats in vivo and in human skin fibroblasts in culture. The deuterated iso-VLCFA was degraded to the corresponding 16- and 18-carbon iso-fatty acids by rats in vivo and by normal human skin fibroblasts in culture, but there was little or no degradation in peroxisome-deficient (Zellweger’s
syndrome) fibroblasts, indicating that its oxidation was peroxisomal. Neither the 14-, 20-, and 22-carbon iso-fatty acids nor the corresponding odd-chain metabolites could be detected. In the rat, the organ containing most of the iso-lignoceric acid, and its breakdown products, was the liver, whereas negligible amounts were detected in the brain, suggesting
that little of the fatty acid crossed the blood-brain barrier. Our data indicate that VLCFA labeled with deuterium at the
ω-position of the carbon chain are suitable derivatives for the in vivo investigation of patients with defects in peroxisomal β-oxidation because they are metabolized by the same pathways as the
corresponding n-VLCFA. Moreover, as iso-VLCFA and their β-oxidation products are readily separated from the corresponding n-fatty acids by normal chromatographic procedures, the turnover of VLCFA can be more precisely measured.

The proportions of the different lecithin fractions have been determined in HeLa and KB tissue culture cells and Ehrlich Ascites
tumor. 82.8% of the total phosphatidyl choline phosphorus is found in fraction 3 of HeLa cells. The major phosphatidyl cholines
found in KB cells and Ehrlich Ascites tumor are in fractions 3 and 4 and representing 66.6% and 88.7% of the total phosphatidyl
choline P, respectively. The incorporation of 1,2-14C-choline and 1,2-14C-ethanolamine into the various phosphatidyl choline fractions has been assayed to determine their biosynthesis in Ehrlich
Ascites tumor. The incorporation of 1,2-14C-choline into fractions 3 and 4 is 100 times the 1,2-14C-ethanolamine. This evidence indicates that the methylation pathway of phosphatidyl choline synthesis is very low in HeLa,
KB and Ehrlich Ascites cells.
