毕业论文综述整段翻译

Heart sounds is normal or pathology can reflect the heart of acoustics, it is due to the heart throb process in open and close the valve and myocardial blood and movement produced vibration. Through in vitro for human organs, medical personnel activities of the lesion and preliminary judgment can cause, clinical work often with stethoscope. The traditional stethoscope although the use of simple, but often difficult to capture inside the body organs issued some weak but very important biological and environmental noise is larger also, have led to doctors being unable to make timely diagnose and diagnosis based on the experience, according to the doctors, at the same time, because of poor accuracy pressure pipe pressure problems in his ears are uncomfortable with the biggest drawback is not output signals to store, recording, display and heart, unfavorable cardiography medical graduation thesis will in knowledge and skills, on the basis of the specific characteristics of the heart, combined with appropriate treatment method for the design of a clinical teaching of electronic auscultation teaching instrument multi-purpose. It is a kind of batteries, easy to carry to ward, with portable auscultate teaching electronic instrument.

第一段翻译如下Cardiac sounds is that being able to reflect the heart is regular or the pathological mechanism audio , it are that every valve's coming untied shuts and oscillation produced by cardiac muscle and blood motion takes form in process since the heart beats rhythmically. Pass extracorporeal gain flexible human body internal organs organ sound, medicine protects a personnel being able to be preliminary judging out nidus and cause of disease , often need to be backed by a stethoscope in clinical job. Clinical tradition stethoscope sometimes is difficult to catch the few faint but but very important living things sound that the visceral organ issues to inside of the human body although using a simplicity,the effect accepting ambient noise is also bigger, lead to a doctor have no way to do out the correct diagnose in time, diagnostic experience , accuracy according to being based on a doctor mainly are relatively poor and, problem squeezes the medical science being that the unable output electric signal does memory , the sound recording , demonstrating and depicting mark cardiac sounds picture, Bu Li Yu in extremely not comfortable maximal ear lining shortcoming in at the same time since pressure is in charge of pressure teaching.第二段翻译如下My graduation thesis mounts the basis in the what be grasped knowledge and technology , to designs combining with the cardiac sounds characteristic concretely , adopt the right treatment means. It is that one kind of reason is battery-powered , easy to carry arrive at a ward , provides the auscultation teaching electron instrument with the portable type.文章有些长、、标准人工翻译、、希望可以帮助你、、

无机械时滞时间分辨泵浦-探测实验的超快激光脉冲触发反应与一第二脉冲以引起的变化的一个快照。通过改变相对于泵的脉冲刺激过程中可以遵循的时间脉冲到达时间。通常情况下，探针脉冲延迟与机械泵脉冲延迟线。虽然该方案已在过去的几十年中得到广泛应用，但仍有一些明显的缺点。这些缺点可以通过使用略有不同的两个同步的激光器克服但稳定的脉冲重复率。该方法避免了机械延迟线需要被称为异步光取样（阿索波斯）。时间分辨率下可达10 ns的时间测量窗口100 FS可以达到。在下面我们会解释和描述这种方法和实验结果的应用。本系统，一个领先开发商和高精度计量仪表的全球供应商，成立于2001为分拆量子光学的马克斯普朗克研究所。著名的诺贝尔奖的光学频率梳技术，根据公司提供的基于在工业和研究应用超快激光器和同步电子完整的解决方案，慕尼黑。我们所有的产品都是根据精益制造标准制造。我们认为，精益生产支持我们的力量在听客户的制造在一个快速和有效的方式。用脉冲持续时间可达几个飞秒短脉冲激光的发明（1 FS = 10-15秒）打开这个时间尺度上测量不同样品的超快动力学的可能性。在超快时间分辨光谱反应是由飞秒激光脉冲也被称为泵的脉冲触发。第二激光脉冲的脉冲，称为探针，用于探测样品性质的变化（例如，吸收，反射，荧光，等。）。通过改变相对于泵的脉冲激发过程可以在时间[ A. Zewail，随后的探针脉冲的到达时间的诺贝尔讲座，1999 ]。这样，在样品的过程可以用在激光脉冲的持续时间的顺序的时间分辨率。通常情况下，在一个时间分辨泵探针实验两个泵和探针脉冲源于同一激光除以每个激光脉冲输出为两个独立的脉冲。探针脉冲延迟与机械延迟线[泵脉冲例如j-c. Diels，W.鲁道夫，“超短激光脉冲现象”，学术出版社，爱思唯尔]。采纳哟 亲！
