Based on the model, closed-form expressions for cumulative distribution function of the output signal-to-interference plus noise ratio and symbol error rate of MIMO MRC systems with equal-power and unequal-power CCI are derived respectively.

在此基础上，分别推导出具有相等功率和互不相等功率的共信道干扰下系统输出信干噪比的累积分布函数和误符号率的闭合表达式。

On the base of the acoustics , a whole linear time - varying discrete speech produce model is established through anatomising the factors including track , driving source and lip eradiation the mechanism of speech in this paper , and we draw a conclusion that the time between glottal closure is pitch period

本文从声学理论出发，剖析了语音产生的机理，综合考虑声道、激励源和嘴唇辐射三方面的因素，建立了一个完整的、线性的和时变的语音产生的离散系统模型，得出两次声门闭合事件之间的时间间隔就是基音周期的结论。

The cause of the heat-wave during the drought is the intensified Rossby wave over the Eurasia continent,which results in a closed warm anticyclone over the drought area,then an adiabatic warming is caused by the strong sinking motion.

华北地区夏季热浪天气的成因：(1)夏季欧亚大陆Rossby长定波波列的维持并发展，使得干旱区域上空出现闭合暖性高压系统，其强烈下沉运动引起空气绝热增温(2)局地干旱维持与发展使得干旱区内潜热大大降低，近地面感热以及向上长波辐射的增加使得干旱区域气温持续升高。

This study started from the characteristics of the speech system in the postoperative cleft lip and palate children with velopharyngeal incompetency, analysed the causes and characteristics of the speech disorders in those children, considered the rules of the auditory development in healthy children, followed the rules of combining the therapy for the causes with the therapy for the symptoms and combining the traditional therapy skills with modern techniques, and then built up a framework of speech therapy for those children basically.

本研究从唇腭裂术后腭咽闭合功能不全患儿言语系统结构的特点出发，从此类患儿自身言语功能障碍的成因及其特点入手，兼顾普通儿童听觉发育的规律，遵循对因矫治与对症矫治相结合、传统矫治方法与现代技术相结合的原则，初步提出了一套针对此类患儿言语障碍的矫治框架。

If it is feasible, the closed noninteractive literature-based KDD process can be used to prove the legitimacy of the open discovery process. This system also deals with "Title" and "Abstract" respectively in the light of Swanson"s method and retrieves the correct "B" word between the start literature"A" and the target literature"C.

系统采用的是Swanson教授本人的闭合式知识发现算法，同样对标题和摘要都进行了处理，结果发现用标题计算仅能求得部分中间词，而用摘要计算可以求得几乎所有期望得到的中间词，可见此算法处理摘要的效果优于处理标题。

At the level of single factor,a method for diagnosis of data error in plane control survey was put forward systematically.

在单因素水平上，提出了平面控制测量数据超限时，粗差的系统诊断方法，以C语言为基础，开发了相应的诊断模块，并给出算例，检验了模块的有效性，为检验导线闭合差是否超限提供了方便。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
