Objective Base on the Neighborhood activation model, to develop the Mandarin Multisyllabic Lexical Neighborhood Test, which is exoected to be useful for evaluating speech perception performance in children with hearing loss.

根据邻域激活模型，邻居词汇数目较少但在口语中出现频率高的目标词定义为"易词"，邻居词汇数目较多但在口语中出现频率低的目标词定义为"难词"。

Transmitter is composed of 555 core multivibrator, by changing the oscillator frequency to adjust the frequency of infrared emitter, and can adjust the resistance to reduce the infrared signal duty cycle to increase as much as possible infrared the scope of protection.

详细说明：发射电路是以555为核心组成多谐振荡器，通过改变振荡器的工作频率来调节红外发射器件的工作频率，且可以通过调节电阻来减小红外信号的占空比，从而尽可能地增加红外防护的范围。

Working characteristic of Fe-based metal glass Fe36Co36B20Si4Nb4 core, the relationship of frequency, field current and induced voltage, the relationship of magnetic permeability and input frequency were studied. Effective magnetic permeability of Fe-based metal glass Fe36Co36B20Si4Nb4 as mutual iron core was measured using mutual induction method.

研究了Fe36Co36B20Si4Nb4铁基环状金属玻璃作为互感器铁芯材料的工作特性，即频率、励磁电流与感应电压之间的关系；磁导率与输入频率之间的关系，并采用互感方法测量了铁基金属玻璃Fe36Co36B20Si4Nb4作为互感器铁芯的有效磁导率。

It is the natural frequency of emission of the hydrogen atoms in space and was discovered by us in 1951

这个频率是空间氢原子释放的自然频率，是在1951年被人类发现的。

So the natural frequency in still water can be used in the case of moving water.

因此，可以用结构在静水中的固有频率近似结构在动水中的固有频率。

The frequency response shows a dominant natural frequency at 1,333 Hz.

频率响应表明，主导自然频率，在1333名赫兹。

Then,we improve CSFP Model in two aspects:when we ascertain the frequency of default,we use negative binomial distribution to substitute Poisson distribution so that the model can measure the data better;when we ascertain the loss distribution of default,we use Γ-distribution to substitute normal distribution.

其创新与特色一是对贷款组合的风险暴露数进行分段，在每一频段上分别确定风险暴露数分布，进而可以更准确的描述各笔贷款的风险暴露数。二是在确定风险暴露数分布时，用Γ分布替代了传统的正态分布，解决了贷款违约的风险暴露数分布的厚尾问题，进而解决了大宗贷款违约的风险度量问题。三是确定违约频率时，用负二项分布来代替传统的泊松分布，解决了违约频率的方差通常要大于其均值的分布拟合问题。

However, there was no significant difference in the frequency of genotype Gly/Gly and allele Gly in NNA group, compared with control group.

然而，NNA组与对照组的基因型Gly/Gly频率和等位基因Gly频率无显著差异(P＞0.05)。

The accuracy of further calculations of the nonharmonic constants, frequency distribution of tidal level and high tidal level with the multiplier 2 hours are all dependent on the results of the harmonic constants derived above. Calculations of the nonharmonic constants will be different if the type of the harbor changes.

调和常数是否稳定决定了进一步计算的非调和常数、潮位频率分布和2小时乘高潮位频率分布的可靠性。

Methods -3489C/T and 478C/T polymorphism were screened in 196 type 2 diabetic patients and 119 normal controls by polymerase chain reaction restriction fragment lenth polymorphism method.

运用聚合酶链反应-限制性片段长度多态性技术对196例T2DM患者和120例正常对照者的-3489C/T与478C/T多态性进行检测，并比较各组间基因型频率和等位基因频率以及相关临床资料。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
