The left ventricular ejection fraction and stroke volume were measured by Simpson method of automatic tracking endocrinal. Results Vs and SRs of GI were significantly lower (P.05) than those of the control group, and Vs, SRs and ε of GⅡ were lower (P.05) than those of GI.

结果 病变Ⅰ组23例各节段左心室最大纵向运动速度、应变率均明显低于对照组(P.05)，病变Ⅱ组10例各节段最大纵向运动速度、应变及应变率均明显低于Ⅰ组(P.05)；组间左心室射血分数、每搏量差异均无统计学意义。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。

Shock Till You Drop 休克直至你辍学 has learned from an anonymous source at Twentieth Century Fox that a third chapter in the Alien vs. Predator franchise is a "certainty." At this point, it is unknown if brothers Colin and Greg Strause, who helmed Aliens vs Predator - Requiem , will be involved with the sequel.

The photopolymerization led to stable latices and they were obtained with neither coagulation during synthesis nor destabilization over time. It was found that the obtained MMA homopolymers exhibited relatively narrow molecular weight distributions(PDI=1.27—1.36), which was characterized by GPC. The plots of number-average molecular weight vs. conversion and ln([M0]/) vs. time were linear respectively, indicating that the reaction was a controlled/living free radical polymerization.

结果表明，该细乳液体系非常稳定，在整个聚合过程中即没有絮凝物产生，也没有沉淀析出，获得了良好的ln([M0]/)与时间、数均分子量与转化率之间的线性动力学关系，并且在整个聚合反应过程中MMA均聚物的分子量分布比较窄，其多分散性指数较低(PDI=1.27~1.36)，具有明显的活性聚合特征。

Methods: there were 40 youth Essential Hypertension patient examples who measure up , 20 cases as the group with electro-acupuncture Quchi and Taichong were observed vs 20 cases as the group with Catto pulley,observe the blood pressure and the principal clinical symptom;6 Essential Hypertension rats as the group with electro-acupuncture Quchi and Taichong were observed vs 6 Western medicine Catto pulley group、6 un-disposal sential Hypertension rats,observe the blood pressure、the plasmodia Noradrenalin and AngiotensionⅡlevel change.

临床试验将40例符合纳入标准的青年原发性高血压患者，按就诊顺序随机分为电针组和对照组各20例，分别给予电针曲池、太冲穴和口服卡托普利治疗。观察治疗前后血压、临床症状总积分及主要症状的变化。动物实验将自发性高血压大鼠18只随机分为3组，每组6只，分为电针组、卡托普利组和模型组，2周后观察各组的降压疗效，及血浆去甲肾上腺素、血管紧张素Ⅱ含量的变化。

For the sake of simplicity, the culture was deemed polymicrobial if at least 3 different bacterial species grew out and if the species were of 2 different types (i.e., gram-negative vs. gram-positive, aerobic vs. anaerobic).

简单起见，培养结果假如有3种不同细菌生长或有两类细菌（如格兰阳性和革兰阴性，需氧菌和厌氧菌），这种结果被人为是复合感染。

Results The effective rate of heartburn, swallowing pain, retrosternal pain and dysphagia in two groups was 85.7%, 89.3%, 75.0%, 82.1% vs 82.1%, 89.3%, 82.1%, 85.7% and that of mucosa-damage in gastroscope was 89.28% vs 85.71%.

结果 两组病人的症状改善程度差异无显著性，胃镜下黏膜损害改善程度差异亦无显著性。

The activities of TchE and MAO in cerebra of Liang Zhu group significantly decreased (P.05, vs control group; P.05, vs Mozart group). But the activities of TchE and MAO in Mozart group have no difference compared with the other groups.

梁祝音乐组与对照组、莫扎特音乐组相比，小鼠脑组织TchE和MAO活性均明显减少(P.05)，而莫扎特音乐组的TchE和MAO与其它两组比较差别不大。

Unusually prevalent religion vs. extreme secular belief; unrestrained power vs. powerless society; working hard in the fields and living thriftily, but never believing in the meaning of one's own life. This is the basic reality of Dragon King Village, a common village in the west.

异常普及的宗教和极端世俗的信仰；不受约束的权力和没有威权的社会；在土地上辛苦劳作、勤俭生活却丝毫不相信自己生活的意义，这就是龙王村——一个普通西部乡村最本质的现实。

The relationship between the tracking error and those auxiliary errors is clearly established when plant relative degree is greater than one and therefore, it can be proved that the influence of averaging filters on a VS-MRAC system can be considered as, in a sense, an unmodelled dynamics. As a result of this, it is shown that the stability analysis of a signal synthesis based VS-MRAC system must be modified to include the 'unmodelled dynamics'.

当对象建模部分相对阶大于1时，得到了系统跟踪误差和辅助误差间明确的关系表达式，进而证明平均值滤波器对系统的影响相当于未建模动态对系统的影响，这表明以往相关文献关于系统稳定性的分析是有缺陷的，没有将平均值滤波器对系统稳定性的影响完全考虑在内； 3。
