二氯双（三笨基膦）合铂的合成及应甩

本文确定了硅氢化反应催化剂二氯双(三苯基膦)合铂的合成路线及合成工艺。同时研究了它在硅氢加成中的应用，结果表明以二氯双(三苯基膦)合铂代替氯铂酸异丙醇体系，使某些反应的产率有较大提高。并对硅烷偶联剂及功能有机硅化物的发展可以起促进作用。     

喝酸奶吗——酸奶定义

酸奶，学名“酸牛乳”。是经用特殊的微生物使奶发酵后制成的产品．其特性是保存温度较低、保质期较短。     

酸析-絮凝法处理青霉素、头孢废液的实验研究

采用酸析-絮凝法预处理废液。研究发现当单独处理青霉素废液,COD去除率平均为66.9%,但废液pH值不稳定。而头孢废液处理效果不明显。将两种废液混合处理取得了良好的效果,COD去除率平均达到了89.3%,且pH值比较稳定。达到预处理目的,大大降低了处理费用。     

熟悉的地方，我看到了风景

有时候,总是找不到一种语言能够诠释自己的悲伤;有时候,总是找不到一种方式能够释放自己的沉重。于是,喜欢透过斑驳的夜色,沿着记忆的纹路,细数自己昨日的幸福。这一切,只因为,我是一名教师,但我不爱它。教师这个职业,说起来圣洁,听起来光彩,     

面对学生不太愿意质事咋办？

在学校的管理中,班主任担负着极其重要的作用,一个班级的班风、学风的好坏与班主任有着极其密切的关系。笔者对在北大附属实验学校担任班主任工作一年期间的酸甜苦辣的确感受很深,面对学生不太愿意的事该如何处理,是任职来思考最多的问题。     

Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.

野茉莉的幽香

悦荐如果你善于发现事物的真、善、美,那么你便能闻到野茉莉那沁人心脾的香味;如果你只会发现事物不好的一面,那么就只能等着那火车头的浓烟来呛你了……推荐人:上海市东昌中学东校初二褚佳莹高中时代,我参加了一个合唱团。团里分成女高音、女中音、男高音和男低音四个声部。大概因为没经验,演出时,常有人在不该自己唱的时候开了口。最可怕的是,当大家都静默的时候,突然听见高亢的一声从队伍里冒出来,说多臭就有多臭。我们管这种情况叫"放炮"。     

让小学语文课有趣、有情、有美感

曾经,我们为了追求所谓的轰轰烈烈将之遗忘,为了追求所谓的别出心裁将之忽视,所以,如今的语文课不是像白开水那样乏味,就是像打翻五味瓶那样酸甜苦辣咸兼有。而今,我们幡然醒悟：首先要使语文课变得纯净,然后再让语文课有趣,有情,有美感。
