Test results of EMP-steel frictional pairs showed that the wear rate h of EMP, press p andvelocity v are suited to equations separately: h =m .p n and h =a .v b.

试验证明EMP复合材料瓦与钢对磨时的磨损率h与压力p、速度v之间分别满足h=m.pn和h=a.vb关系式，给出了相应系数m、n、a、b的值；磨损率与钢试件表面粗糙度Ra之间满足h=A·RaB关系式，给出了A、B的有效范围值。

In this note, we show that for any two matrices A and B over a generalized quaternion algebra defined on an arbitrary field F of characteristic not equal to two, if A and B are similar and the main diagonal elements of A and B are in F, then their traces are equal.

本文对于特征不是2的任意域F上定义的广义四元数代数上的两个矩阵A和B，给出如果A和B相似并且它们的主对角线上的元素在F中，那么它们的迹相等。

In this note, we show that for any two matrices $A$ and $B$ over a generalized quaternion algebra defined on an arbitrary field ${\bf F}$ of characteristic not equal to two, if $A$ and $B$ are similar and the main diagonal elements of $A$ and $B$ are in $\bf F$, then their traces are equal.

本文对于特征不是2的任意域${\bf F}$上定义的广义四元数代数上的两个矩阵$A$和$B$，给出如果$A$和$B$相似并且它们的主对角线上的元素在${\bf F}$中，那么它们的迹相等。

In chapter four, we make an enquiry into a special A shi Astructure which functions as a mean of emphasizing and euphemizing and expresses pragmatic quantity.

第四章，主要考察表达语用量的特殊格式"A是A"的表强调和委婉的语用功能。

If in one language the existence of A includes B, while in the existence of B does not imply A, then in the language A is more markedness than B.

既：如果一种语言中的A的存在包含着B的存在，但是B的存在不包含A已经存在，那么现象A比现象B更具有标记性。

Pisier\'s results,under tree martingale valued space X is isomorphic toan a-uniformly convex space (2≤a＜∞),some quasi-normal or normal inequalitiesof a-variation maximal operator and a-conditional variation maximal operator of X-valued predictable tree martingales are identified.

同时，用G.Pisier's结果在树鞅取值空间X同构于a一致凸Banach空间条件下，证明了几个X-值树鞅α-方极大算子和a-条件方极大算子的拟范数不等式与范数不等式。

Polymer A is a acrylic copolymer containing 70% by weight of methacrylic acid and 30% by weight of methyl methacrylate prepared by a catalytic chain transfer method to give a polymer having a number averaged molecular weight of approximately 600 as measured by GPC.

聚合物A是丙烯酸共聚物其含有甲基丙烯酸重量70％，按重量的30％甲基丙烯酸甲酯的催化链转移的方法准备给予聚合物具有的平均人数约600分子量为由GPC测定。

Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

An. minimus A and C can be visually distinguished according to the specific bands in agarose gel. For ASA, specific bands of 294bp and 112bp represent An. minimus A and C, respectively. In RFLP, three fragments of 376bp, 268bp and 108bp were observed for An. minimus A, while only a band in 376bp for An.

在PCR-ASA在PCR-ASA中，两亲缘种除在376bp处均有一条条带外，分别在约294bp和112bp处出现各自的特异扩增带；PCR-RFLP的结果是，微小按蚊A在约376bp、268bp和108bp左右出现3条条带，而微小按蚊C仅在376bp处存在唯一条带。

The half steps occur between the second and third degrees of the scale, and between the fifth and sixth degree. Thus the natural minor scale of A minor can be played on the white notes of the piano from A to A.
