Results As the results, there was 6 patients with the ILVT cycle length of (286±38)ms. The indicaed site of EA by noncontact mapping was at the middle septum in 4 patients, and at the inferior septum in 2 patients. Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.

6例ILVT周长为(286±38)ms，非接触标测显示4例激动起源位于中间隔，2例位于下间隔，EA较体表QRS波提前约(48.6±32.8)ms，传导径路长约(2.6±0.9)ms.6例病人在窦性心律下消融导管起搏标测12导联QRS形态与ILVT相匹配(≥11/12)处位于EX，而非EA(≤10/12)见正文。6例病人在室性心动过速期间消融导管于EA和CP处标测到PP，2例于EA标测到DP，1例于EX标测到PP.6例病人在窦性心律下于ILVT起源部位行片状或／和传导径路作线性消融均获成功，随访(12±6)月，未见复发。

Molybdenum exists in soil and plants at very low levels. Its quantitative detection is in the range from ppm to ppb. Satisfactory results can be obtained by the use of polarography.

土壤和植株中的钼是含量很低的化学元素，定量分析检出范围是pp~m-pp~b数量级，采用极谱法分析可获得满意的结果。

This paper built water quality assessment model based on some basic introduction to PP. It made several conclusions as follows: PP model was stable when sample size was no less than 20. It run much faster when the range of projection vector was constrained between 0 and 1. Accelerated genetic algorithm should be recommended because of its unique advantages. Using scatter diagram of making comparison directly was more convenient than using regression model.

该文在介绍该模型基本计算步骤的基础上，经建模分析，得出：各评价等级取值范围内样本个数不小于20即可具有较好的稳定性，投影向量分量的取值范围为[0，1]时更有利于提高计算速度，选用加速遗传算法寻优时间更短，使用图解法或直接比较法更为方便和快捷。

This result was consistent with the previous simulation study;(2) the signals of MAH onto the radical chain ends with double bonds increased markedly with increasing MAH content, indicating that P scission occurred after MAH attached to the tertiary carbons.

MAH的用量对接枝PP链的等规度有很大的影响，主要表现在随MAH浓度增加，PP链的mm序列所占的比例逐渐增大，mr和rr序列所占的比例逐渐减小。

It results in decreasing in spherulite size,increasing in crystalline density,and eventually causing an improvement of optical properties.
