如果能做到这样的话，扬声器纸盆的运动就能最准确地反映出所施加的电压的变化。换句话说，就是失真会最小，因为在这种情况下，扬声器的运动部件会在最小的时间和空间误差下，运动到期望的位置。

objective inquire into the value of eet and cag in the diagnose of coronary heart disease.methods review and analyze132cases of positive eet and77cases of results of cag.results positive cag:58cases（75%）;negative cag:19cases（25%）;single-branch pathology18cases;double-branch pathologies:40cases;many-branch pathologies:19cases;stc extension:25cases;s-wave deepeness:21cases;u-wave inverˉsion:2cases.conclusion among the patients of eet,dangerous factors conform to the results of cag inclinical symptom relatively,among females,young people and non-clinical symptom,false positiveness is more.

目的 探讨活动平板运动试验与冠状动脉造影在冠心病诊断中的价值。方法对132例活动平板运动试验阳性，77例冠状动脉造影结果进行回顾性分析。结果冠状动脉造影阳性58例（75%），阴性19例（25%），单支病变18例，双支病变40例，多支病变19例，stc延长25例，s波加深21例，u波倒置2例。结论在活动平板运动试验患者中，有危险因素和临床症状与冠状动脉造影结果较相符，女性、年轻人和无临床症状者假阳性较多。

Long-term aerobic exercise can effectively prevent hepatocyte number from decreasing accompanying with aging. Among the groups of aged, results showed that rats of 1-hour and 2hours group whose recovery function of hepatocyte apoptosis were of most significant. The increasing number of hepatocyte might be one of the cytological mechanisms of how aerobic exercise delays cell aging. Further researches on the phenomenon of the anomalous change of the hepatocyte apoptosis ratio among the youth groups are needed expectably.

肝细胞凋亡存在随增龄明显下降的趋势，这对维持肝细胞数量或缓解增龄过程中肝细胞数目丢失具有十分重要的意义；长期有氧运动可以有效的阻止肝细胞凋亡率在增龄过程中下降的趋势；在老年前期组中，训练1小时和2小时组对肝细胞凋亡能力的恢复作用最明显；有氧运动促进肝细胞凋亡能力的提高可能就是有氧运动延缓细胞增龄发生和发展的重要细胞学机制之一。

Among people who do exercise regularly, those--elder, non-smoker, perceiving unhealthy, no income or low level of income and practicing exercise often with partner—were more likely to carry on the effective fat-reducing exercise. This study identified the groups of overweight and obesity and their association with practicing exercise habit and health fitness.

结果显示龄较高、男性、教育程较高、无吸菸、有患慢性病、无烦恼、最近星期无身体适影响生活作息、工作家事耗体、收入在60000 元以上者及收入在19999 元以下者，其进运动与的可能性较高；高龄、无吸菸、自认健康好、无收入或低收入与经常有运动同伴者，其进有效减肥运动的可能性较高。

For high-speed sliding-barge dolphin unsteady movement and kinetic theory forecast problem in the wave, because its kinetic differential coefficient equation is complicated furthermore comprises many presumptions and premises, it meads to be calculated by a large-scale computer.

针对高速滑行艇海豚不安定运动以及在波浪中的运动理论预测问题，因其运动微分方程式繁杂而且有许多假设和前提，需要在大型计算机上计算。

Results Fascicles and certain amount (207) of motor fibers from the anterior division of C7 were distributed to musculocutaneous nerve and median nerve, the orientation of these fibers were not clear. The ones (323) from posterior division were to the axillary, radial, and dorsal thoracic nerves, thus the orientation of these fascicles was relatively definite.

结果 大鼠C7神经根前股发出一定数量的运动纤维到肌皮神经、正中神经，总量约207根，但在C7前股定位不明确；后股发出相应的运动纤维束支到桡神经、腋神经与胸背神经，总量约323根，这些束支在C7后股的定位较明确。C7神经根所支配的范围很广，其中以C7后股发出的胸背神经束支支配的背阔肌占比例最大（运动纤维含量＞50%）。

It is key point to understand how to restore the sporters'energy after they exercise during train seasons.After swimmers took supplement of the beverage compounded taurine designed for swimmers during training,their hemanalysis and kinesiology experiment were carried on. The experiment result testifies swimming sporters' tolerant and kinetic capability had been improved, did not have the overfatigued during the winter training.

运动训练中如何更好地促进运动员机能的恢复是训练中的重要环节，针对游泳运动员的特点，在训练中进行牛磺酸复合功能性饮料的补充，并在补充前后进行有氧功率自行车的运动测试和血样的分析，结果表明运动员有氧耐力水平和运动能力都有一定的提高，冬训期间未出现过度疲劳的现象。

By analyzing the motive properties of a carrier, this paper sets up a mathematic model for predicting its moving trends, and based on which, the terminal guidance of predicted impact is adopted.

通过分析航母的运动特性，建立了预测其运动态势的数学模型；在此基础上，采用预测落点的末制导方法，在导弹弹头再入大气层后，通过多次预测和修正，实时修正由于航母运动和再入过程中大气影响等各种干扰因素所引起的落点偏差，以保证弹头能以较好的精度命中目标。
