The research work in nonlinear pulsatile flow and nonlinear pulse wave propagation is reviewed.

本文首先回顾了前人在弯曲动脉中脉动流和脉搏波传播方面的研究工作。

Raby, from Brigham and Women's Hospital and Harvard Medical School in Boston, Massachusetts, and colleagues from the Childhood Asthma Management Program Research Group.

Raby以及其来自儿童哮喘管理计画研究团体的同事指出，在儿童罹患哮喘的研究中，有关哮喘儿其与父系哮喘病史和并发空气传播途径过度反应症的关系之信息很少。

It is valuable to use GIS technique predicting the radio wave propagation on mobile communications.

在移动通信中应用GIS技术进行无线电波传播预测是一项很有价值的工作。

It is suggested that the nature of Talbot serf-imaging is the recordation and reappearance for periodic space information of object by photons.

与此同时，提出了塔尔博特效应实际上是光子对周期性空间信息的记忆与再现的过程，从而对光子在光传播过程中携带空间信息产生了一定认识。

Based on the theory of stimulated Reman scattering, this paper discusses the SRS of N_2 in the atmosphere and its effects on high power laser beam propagation.

大气中的受激喇曼散射作为强激光大气传播的非线性效应之一，在当前日益引起人们的重视和关注。

By slightly increasing the separation of the two plates in the middle,a double-crystal structure forms,which allows acoustic waves to resonantly tunnel through it,with transmission peaks observed inside the band gaps.

处于带隙频率范围内的声波或者弹性波将被禁止在声子晶体中传播。

This method has important applications in the analysis and design of laser resonator.

光学谐振腔的传播圆－变换圆的图解分析与设计方法具有简单，形象直观等优点，该方法在激光谐振腔设计和分析中有着重要的应用。

Aphids belong to Diptera insect pests; they damage plants directly by sucking juice of phloem, and indirectly by spreading plant disease. The plant lectins are proteins that bind reviviscence to specific mono- or oligosaccharides; therefore they have potential in plant genetic engineering.

本研究还克隆了植物凝集素基因，以解决棉花蚜虫的危害问题，蚜虫属同翅目昆虫，通过吸取植物韧皮部的汁液造成直接危害，又通过传播植物病害对植物造成间接危害，植物凝集素是一类具有特异糖结合活性的蛋白，在植物基因工程中具有较大的应用潜力。

When the researchers used their computer model to track how sound waves travel in the whale's head,they were surprised to find thar sounds comming from right in front of the whale actually travel under the animal's jaw.

当这些研究员使用电脑模拟声波在鲸鱼脑中传播的时候，他们惊奇的发现，从正前方来的声音，实际上是传送到了他们的下颚。

In Chapter 2 the source extent and rupture direction of this earthquake is studied.

在第二章中，研究了这次地震的震源尺度和破裂传播的方向。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
