一、四川省在未来大西南联合反空袭战役中的地位与作用。 (一)四川及周边地区经济地理状况分析: 四川省以南为云贵高原,其地势东低西高,平均海拔由2000米左右下降到1000米。广泛分布石灰岩层,由于长期遭受流水的溶解侵蚀,形成石林、溶洞、地下河等喀斯特地形。云贵高原山岭丛多,地面崎岖不平,只有山岭之间的一些小盆地(当地人称为“坝子)比较平坦,是高原上人口集中的农耕区。云贵高原从川南方向形成一道天然屏障。 相似文献

The purpose of an open primary is to incorporate more moderatevotes into the primary elections. This intention may backfirewhen nonparty members strategically participate in theprimary, and the result of an open primary might become even moreextreme than when nonparty members are not allowed to participate.Realizing this, the party members might also votestrategically to counter-react. If this occurs, then it mightactually coordinate the votes of the party's supporters. Theeffect of strategic voting behavior on the result of aprimary depends on the size of the party, turnout rate ofnonparty members, the positions of the candidates and theproportion of voters who vote strategically. Strategic votingbehavior can sometimes improve social welfare. 相似文献

This study was designed to compare the qualitative results and concentrations of methamphetamine (MA) and its metabolite amphetamine (AP) in head hair and hair collected from different parts of the body (axillae and pubis). Hair from subjects (N = 14) suspected MA users was simultaneously collected. Hair preparation involved washing step, fine cutting, overnight extraction, derivatization by the trifluoroacetic anhydride, and gas chromatography/mass spectrometry (GC/MS) using selective ion monitoring. In this study, we found a good correlation of the qualitative results for MA between head hair and hair on other parts of the body, but there were some differences in concentrations of MA and AP. Namely, the concentrations of MA and AP were higher in axillary and pubic hair than in head hair. 相似文献

Allele frequencies for the fifteen short tandem repeats (STR) loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, D19S433, THO1, D16S539, CSF1PO, TPOX, D2S1338 (AmpFl STR Identifiler PCR Amplification Kit, Applied Biosystems) were determined in a population sample of unrelated China Han in Jilin Province, China. Statistical analyses were performed using Powerstats version 1.2 and GEP-ISFGWG. The results showed that all the loci met Hardy-Weinberg expectation. 相似文献

The prevalence and age distribution of 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylenedioxyamphetamine (MDA) in hair samples by gas chromatography/mass spectrometry (GC/MS) were studied. The recoveries obtained from hair were 97% and 99% for MDMA and MDA, respectively. The inter- and intra-assay precision and accuracy were determined. Out of 791 hair samples, 44 (5.6 %) contained MDMA and/or MDA. Out of these 44 subjects, urinalyses from 35 were negative for both MDMA and MDA, while only 9 were positive. We also evaluated concentrations of MDMA and MDA, and the metabolite-to-parent drug ratios. This study showed that the abuse of MDMA or MDA was found principally among young adults and male abusers. We found the epidemiology of ecstasy users in Korea between March 2002 and April 2003. 相似文献
