In this part, there is a reasonable explanation to the definition of the reiterative by way of contrast,summary,accounting etc,and the writer has studied reiterative"s category, parts of speech, the function and so on, also made a research of reiterative"s features in HeLin YuLu systematically in an all-round way.

在这一部分对叠音词的定义作了合理的阐释，运用比较、归纳、统计等方法，分析了它的类别、词性、作用等，全面系统地研究了叠音词在《鹤林玉露》中的特点。

The relationship between the relative sensitivity of natural frequency and energy distribution has also been established for nondamping systems.

为了使显示的图形比较清晰和美观，本文还开发了CGE400显示器/卡的高分辨率彩色显示功能，最后将这些功能软件有机地结合在一起，从而构成微机实验模态分析软件系统。

Its well-developed legal system, however, is relatively effective at facilitating collateral repossession as well as the repayment work-out process.

完备的法律制度，不过，是比较有效地促进侧支收楼以及还款工作的进程。

Based on the observation,this paper presents an efficient method to find a suitable neighborhood size,which only requires running the breadth-first search algorithm incrementally,but doesn't need to run the whole ISOMAP algorithm for every possible neighborhood size as those methods based on residual variance do.

和基于残差的参数选取方法不同，该方法只需递增式地运行广度优先搜索算法，而无需就每一个可能的邻域大小分别运行整个ISOMAP算法，从而具有比较高的运行效率。

A simulation is done between MAODV and AODV with software. From the simulation results under different node speed, it indicates that MAODV could decrease the average of ETE delay and offer lower routing overhead effectively. MAODV can complete routing discovery, package retransfer and self-organize when the network topology is changed, MAODV routing protocol is useful to establish Ad hoc networks in military communication.

应用软件对MAODV路由协议和传统的ADOV路由协议进行了仿真，通过在节点不同移动速度下的网络性能进行仿真比较，结果表明，MAODV路由协议能有效地减小分组端到端传输的平均时延，降低协议开销，能够根据网络的拓扑变化进行自组织，完成路由的发现和分组的中转等基本功能，为自组网在军用通信中的运用奠定了基础。

Methods: Our hospital otorhinolaryngology March 2004 to May 2007 the new hospitalized patients with cerebrospinal fluid rhinorrhea (a total of 32) were divided into the experimental group (16) systematically and psychological assessment, and strengthen psychological care; The control group (a total of 16) using traditional psychological guidance, and compared between the two groups of patients with different medical order compliance.

对我院耳鼻咽喉科2004年3月～2007年5月新入院的脑脊液鼻漏患者（共32名）进行随机分组；对实验组（共16名）系统地进行心理评估，并进行心理干预，对对照组（共16名）采用传统性心理指导，比较两组患者对医嘱依从性的差异。

The mean velocity distributions in turbulent boundary layers of smooth surface and two different riblet surfaces are measured with IFA300 constant-temperature anemometer in low-speed wind tunnel to validate the full development of turbulent boundary laye. Friction velocity and wall friction stress of turbulent boundary layer are obtained with the least-squares fitted curve of the sublayer velocity distribution based on Spalding formula, and virtual origin position of riblet surface can be acquired accurately.

在低速风洞中来流速度一定的情况下使用IFA300恒温热线风速仪测量了光滑表面和两种不同尺寸的脊状表面湍流边界层平均速度分布剖面，并验证了试验段湍流发展的充分性；通过应用Spalding壁面公式使用最小二乘法精准拟合了实验测量的边界层内层速度分布曲线，得到了湍流边界层壁面摩擦速度并进一步求得湍流壁面摩擦应力，较准确地计算出脊状表面的虚拟原点位置，并通过与对数律公式拟合结果比较分析，证实了该方法更加准确有效。

So I might be of the brake when I come over the ledge and on the brake on this rock when I get some good traction and then and then off when the traction is a kind of loose, and definitely off the brake when I come down at this corner and I going to make a direction change, so my front wheel can roll fluently with traction.

这里有土会让煞前煞时打滑不过这个石头可提供煞车抓力，所以当我过岩石时我会放掉煞车，然后上这个石头有比较好的抓地力后再刹车，然后当抓地力减弱时再放掉煞车，我下这个转角一定放掉煞车而且我要转弯，所以我前轮可以流畅的滚过且能抓地。

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