The results calculated by the Elovich rate equation showed that K release rates from 1 mol.L-1 HNO3 extraction ＞those from 2 mol.L-1 HNO3 extraction ＞those from H-resin extraction. Elovich equations combining with the data of H-resin and 2 mol.L-1 HNO3 successive extraction could well described the release characteristics of soil K. The correlation coefficients of the equations reached most significant levels (r＝0.956**—0.999**), and standard errors of specific K release capacities between the vaules calculated by the equations and those measured by both successive extractions were smaller(s=1.61 and 3.52). The specific release rates of soil K calculated by the Elovich rate equations were significantly correlated with the indices of soil K availability (the amounts of easily available K, nonexchangeable K, total available K in soils and K absorbed by ryegrass).

研究结果表明：1 mol.L-1 HNO3提取法的释K速率＞2 mol.L-1 HNO3提取法的释K速率＞氢饱和交换树脂提取法的释K速率；氢质交换树脂和2 mol.L-1 HNO3提取法结合Elovich模型较理想地描述了土壤K素的释放特性，拟合方程的相关系数均达极显著水平(r＝0.956**-0.999**)，土壤特征累积释K量的计算值与实测值的标准差较小(s=1.61和3.52)，且通过速率方程计算的土壤特征释K速率与K素有效性指标(速效K、缓效 K、有效K及黑麦草总吸K量)的相关性也较为密切。

The above results showed that physiological AAI pacing maintained a normal EAS and VAS, and improved or enhanced VSS; while nonphysiological VVI pacing and physiological DDD pacing induced the decrease in VSS due to an abnormal EAS and VAS. Furthermore, with increasing the pacing rate, VSS was markedly decreased.The quantitative comparison of parameters of left ventricular systolic function obtained by computerized ERNA showed that AAI pacing induced the significant increases in ventricular ejection rate and stroke volume with concomitant shortening of ejection time.

objective to study the risk factors on esbl producing strains of k.pneumoniae and e.coli.methods aprospective survey on esbl producing strainsof k.pneumoniae and e.coli for a36-month period.results the resistance rates ofe.coli were:98.08%for ctx,73.08%for amc.the resistance rates of k.pneuˉmonialwere;95.74%for ctx,97.87%for amc.the use rate of third generation cephalosporins was much higher than those of esbls nonproducing strains（p.05）.it induce esbls that3rd generation cephalosporins were used extensive.after strenghtening the antibiotic controls,esbls detection rate has gone down.conclusion the factors of infection of esbl-producing strains were the severity diseases,cellular immunological condition,improper medical manipulations.to prevent esbl-producing strains,reasonable antibiotics usage may be the effective measure.

目的 分析临床大肠埃希菌及肺炎克雷伯菌产esbls的危险因素，并加以控制。方法前瞻性监测产esbls菌的情况，并对感染者进行临床调查。结果产esbls的大肠埃希菌、肺炎克雷伯菌的耐药率头孢噻肟钠为98.08%和95.74%，阿莫西林+棒酸为73.08%和97.87%，产esbls菌感染者头孢第三代的使用率（70.21%）显著高于非产esbls菌感染者（39.47%）（p.05）；第三代头孢的大量使用诱导esbls的产生。通过加强抗感染药物的使用管理esbls检出率开始下降。结论严重的基础病、高龄、机体免疫力低下，长期住院者是esbls菌感染的易感宿主，皮质激素、化疗及介入性疗法是esbls感染的高危因素。滥用抗感染药是产生esbls的重要因素，合理使用抗感染药是防止esbls产生的主要措施。

The oxide formed on NbSi2 at 1023 K consists of Nb2O5 and minor SiO2. The Nb2O5 is lose and nonprotective, which spalls from the sample during oxidation. The oxidation kinetics of all the NbSi2 samples at 1023 K follows a linear law. The oxidation rate is intrinsically determined by the reaction rate between the matrix and the oxygen in air, which in turn is determined by the exposure area of the sample.

无论是单晶还是多晶样品，氧化产物均为 Nb2O5和SiO2，生成的Nb2O5易剥落，样品的氧化动力学曲线均呈直线规律，证明NbSi2的氧化过程是一种本征无保护条件下氧元素与基体元素直接反应的过程。

The Federal Reserve said consumer borrowing rose at a seasonally adjusted 2.4% annual rate in February to $2.54 trillion, half the 4.9% pace recorded in January.
