The useful and important tests of sensibility are: testing the vibratory sensation with tuning fork, vibrometer testing for vibratory thresholds, von Frey testing (determined by Semmes－ Weinstein nylon monofilaments or Pressure－ Specifying Discriminator) for cutaneous pressure thresholds, measurement of static and moving two－ point discrimination with the Disk－ Criminator, Moberg's ninhydrin test, O'Rain skin wrinkling test, Picking－ up test, Tinel's sign and electrodiagnostic test.

此文对临床上重要且实用的皮肤感觉功能测定方法如音叉皮肤振动觉定性检查、振动觉阈的振动器定量测定、Semmes－Weinstein尼龙单丝或Pressure－SpecifyingDiscri minator行皮肤压觉阈的测定、用Disk－Criminator进行静止和运动的两点辨别觉测定、茚三酮试验、O'Rain指腹皮肤皱缩试验、捡物试验、Tinel's征电生理检查以及这些检查方法在神经断裂、神经卡压及神经损伤或修复后的恢复等情况中的应用和评价作一讨论。

This paper introduces a single-carrier system with hybrid time-frequency domain Decision Feedback Equalization, in which the short pn (Pseudo-Noise) sequence with fixed waveform replaces the cyclic prefix in the conventional Single Carrier systems with Frequency Domain Equalization, and the long PN sequences composed of several short pn sequences are employed as the channel training sequences to complete the initial estimation and tracking for fast-varying channel.

摘要该文设计了一种联合判决-反馈均衡的单载波频域均衡系统，该系统用固定波形的短pn序列取代常规SC-FDE系统中的循环前缀，并以多个短pn序列组成的长PN序列作信道训练从而解决快变信道的初始估计和跟踪问题。

An existence theorem concerning denumerable 1-homoclinic orbits and countable families of 1-periodic orbits was given under a generic condition; and an intuitionistic de script ion about those orbits was also given.

证明在通有条件下，该异宿环附近存在可数无穷多条1-同宿轨，和可数无穷多个1-周期轨的单参数族，同时对这些周期轨和同宿轨作了直观描述。

Chapter Two Further Study On Two Types of Tone Sandhis Supposed by Traditional Dialectology The further study is relied on the research of F0 and elapsed time, and more phonetic dealing with the original data.

对这一问题的分析将基于论文第一章所论述的上海方言单音节声调和两类变调的声学特性（基频F0和时长两因素），以及在这两个基本声学特性上所作的语音学意义上的对数据的进一步处理。

At length I spy'd a little Cove on the right Shore of the Creek, to which with great Pain and Difficulty I guided my Raft, and at last got so near, as that, reaching Ground with my Oar, I could thrust her directly in, but here I had like to have dipt all my Cargo in the Sea again; for that Shore lying pretty steep, that is to say sloping, there was no Place to land, but where one End of my Float, if it run on Shore, would lie so high, and the other sink lower as before, that it would endanger my Cargo again: All that I could do, was to wait 'till the Tide was at highest, keeping the Raft with my Oar like an Anchor to hold the Side of it fast to the Shore, near a flat Piece of Ground, which I expected the Water would flow over; and so it did: As soon as I found Water enough, for my Raft drew about a Foot of Water, I thrust her on upon that flat Piece of Ground, and there fasten'd or mor'd her by sticking my two broken Oars into the Ground; one on one Side near one End, and one on the other Side near the other End; and thus I lay 'till the Water ebb'd away, and left my Raft and all my Cargo safe on Shore.

最后，我终于在小河的右岸发现一个小湾。我费尽艰辛，好不容易把木排驶到最浅的地方。我用桨抵住河底，尽力把木排撑进去。可是，在这里，我几乎又一次险些把货物全都倒翻在水里。这一带河岸又陡又直，找不到可以登岸的地方。如果木排一头搁浅在岸上，另一头必定会像前次那样向下倾斜，结果货物又有滑向水里的危险。这时，我只好用桨作锚，把木排一边固定在一片靠近河岸的平坦的沙滩上，以等待潮水涨高，漫过沙滩再说。后来，潮水果然继续上涨，漫上沙滩，等水涨得够高了，我就把木排撑过去，因为木排吃水有一尺多深。到了那儿，我用两支断桨插入沙滩里，前后各一支，把木排停泊好，单等潮水退去，就可把木排和货物品平安安地留在岸上了。

It indicates that the N—O bonds in the singlet dimer adsorption configurations are weaker than any other structures, and this is propitious to the NO direct decomposition. 7. Unlike NO molecules interaction with copper atoms, when two NO molecules interact with the adjacent silver atoms, the non-planar structures are more stable than the planar.

同时，单重态的二聚体与相邻的金属铜和银原子作用时，由于电子从金属原子转移到二聚体上的数量最多，因此在这种吸附构型中，金属原子被离子化的倾向最大，同时使得二聚体中N—O键被削弱的程度也最大，有利于NO的直接分解； 7。

It indicates that the formation of NO dimer is favorable to the NO direct decomposition on the copper surface. The Mülliken population analysis shows that the average charge on Cu is 0.66 e, when the singlet state dimer interacts with the copper.

同时电荷布居分析表明，单重态的二聚体与铜作用时，铜原子上的平均电荷达到0.66e，说明在这种吸附形式中铜被离子化的倾向较大，而且这种吸附形式最有利於NO的分解。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
