历史偶然性研究

整个社会的经济状况决定社会的政治、心理、文化,经济对社会这种始原的决定的作用是任何其他因素所不能替代的.除此而外,也有一定条件下给社会以巨大影响的人物、事件、自然因素,这就是历史偶然性的作用.一系列历史事件都是必然性与偶然性的联合表象.偶然的背后是必然.研究历史偶然性,具有极大的理论意义和实践意义.     

浅谈监视居住的适用价值及完善

监视居住执行难，这是侦查机关面临的现实问题。是违法操作，还是“舍弃”不用?为了充分发挥监视居住的作用，为了保证刑事诉讼的顺利进行，有必要对监视居住的适用价值进行探讨，并给予完善。     

结合:以科学态度对待马克思主义的正道

伟大的延安整风运动已经过去了整整 6 0年。 6 0年前这场全党范围的普遍的马克思主义教育运动 ,对于打破“左”倾教条主义的思想桎梏从而进一步解放全党的思想 ,对于提高全党马克思主义的思想认识水平进而确立毛泽东思想对中国共产党和中国革命的指导地位 ,对于团结全党全军并领导全国人民夺取抗日战争乃至新民主主义革命的最后胜利 ,均起着重大而深远的历史影响。在全党深入学习江泽民同志“七一”讲话精神 ,以认真贯彻“三个代表”思想要求的实际行动迎接党的十六大召开的今天 ,再度回顾与思索延安整风运动留下的深刻历史经验 ,对于我们以求实的、科学的态度对待马克思主义 ,求实地、科学地探索与总结中国改革开放实践中遇到的新问题、新经验 ,与时俱进地推动马克思主义的理论创新 ,都将是大有裨益的。为此 ,本刊开设专栏发表这组纪念性的理论文稿。     

营造云南旅游产业软环境的思考

13C4-secobarbital as the internal standard for the quantitative determination of secobarbital--a critical evaluation

In this study, 13C4-secobarbital was used as an exemplar compound to illustrate the mechanism based on which the effectiveness of a proposed internal standard (IS) could be evaluated. A deuterated analog, 2H5-secobarbital, was also studied in parallel for comparison purposes. Well-established solid-phase extraction and methylation procedures were used prior to the GC/MS measurement step. The contribution of the intensity of an ion designated for the analyte (secobarbital) by the proposed IS, and similarly, the contribution of the intensity of an ion designated for the IS by the analyte--a phenomenon termed "cross-contribution"-were evaluated based on a "direct measurement" procedure in which equimolar amounts of the analyte and the IS were used to generate intensity data. These intensity data were then used as the basis for the calculation of "cross-contribution" (in percentages) of ions designated for the analyte and the IS. Cross-contribution data were compared with the linearity data resulting from two series of standards containing 25 to 9600 ng/mL secobarbital using two sets of quantitation ion pairs--m/z 196/200 and 195/199 with 13C4-secobarbital as the IS and m/z 196/201 and 195/200 with 2HS-secobarbital as the IS. 13C4-secobarbital was found to be much less problematic and thus can serve as a very effective IS. Cross-contribution data alone cannot fully explain the observed differences resulting from the use of these two ISs; further systematic study is needed to provide better understanding of the underlying interference mechanism.

气相色谱法测定海洛因含量的测量不确定度评定

目的探讨气相色谱法测定海洛因含量的测量不确定度评定。方法从测定程序分析不确定度来源,并计算各不确定度分量及合成不确定度,得出总不确定度。结果重复性测定不确定度分量最大,气相色谱仪误差次之,而玻璃容量器具天平及对照品所引起的不确定度分量对总不确定度的影响可忽略不计。结论气相色谱法测定海洛因含量的测量不确定度主要来源于重复性测定的误差及气相色谱仪的误差。     

Concentrations of toluene in the body killed by an injury to the head shortly after ingesting thinner

An autopsy was conducted on a male showing leather-like skin damage, revealing the cause of death to be an injury to the head. Thinner was found scattered around the scene of death, and stomach and intestine contents smelled strongly of solvent. Toxicological analysis was conducted to determine whether or not the solvent was of a lethal level. Using gas chromatography, peaks of toluene, xylene, and ethylbenzene were detected in the blood and gastric contents. No toluene was detected in the urine, and therefore it was concluded that the decedent died of a severe head injury shortly after solvent ingestion. In the literature, toluene concentrations in blood and lung samples were determined as both fatal and non-fatal but clear differences in the fatality of toluene in solid organ samples, namely, the brain, liver and kidneys were shown. The brain is especially useful in postmortem analysis. In this case, the concentration of toluene in the brain was 20.0 microl/g, which was considered as a non-lethal level.
