不偏性

This paper is expanded into three main parts to study and analyze the stock time series.1 Through the normality tests, All the sample stock-data curves show different phenomenon of Aiguille and Fat-tail, as well as Left-Deviation, which proves that none of the sample series belong to normal distribution, in other words, the linear method can't be applied into the analysis process, so we adopted the R/S method instead.2 The application of R/S method has verified the long-term memory characteristics of the sample series, and Support Vector Regression is combined to enhance the precision of Average circle period.

文中对股票时间序列从以下三个方面进行了研究和分析：1通过正态性检验，发现各样本股票数据均表现出不同程度的尖峰和胖尾以及左偏现象，证明了所有的样本序列全都不属于正态分布，也就是说明它们不能够适用线性方法进行分析，必须采用重标极差分析方法的非线性方法。2应用R/S分析方法验证他们具有长期记忆的特性，并且结合支持向量回归机提高了测定平均循环周期时的精确性。

Instead of using the homomorphic filter which is used to get rid of multiple noise and is a biased estimator, this algorithm translates speckle into locally stationary additive white noise.

该算法不同于有偏的去除乘性噪声的同态滤波算法，而是将噪声转化为局部平稳的加性白噪声。

The seeds could not be stored for a long time and the number of germination was 50% or so when seeds were cold stored . We can infer through analyzing the inheritance of some character of Gerbera jamesonii that the expression of red flower color of hybrids somewhat trended to that of female parents , plant height、flower diameter and flower doubleness had a declined tendency .

By applying normal testing methods to two different examination papers in this essay, the author obtains the following results: Paper One tallies with normal distribution, indicating that the paper is more reasonable and objective; Paper Two is in the shape of negative skewness and lepmokurtic distribution, showing that the paper is easier than the required and less reasonable.

本文采用数理统计正态性检验法对两份不同的英语试卷考分进行了正态性检验，结果表明：试卷Ⅰ考分的分布服从正态分布，说明其命题难易适当、较为客观、合理；试卷Ⅱ考分的分布呈负偏态、尖峭峰，说明其命题较容易，且不合理。

Through the analysis and investigation on the present teaching program of the representative 26 universities found at present aerobics major course of specialty of physical educationhave many insufficiency: target oretation is imperfect, neglect skill cultivatement; the curriculum content is irregular, insufficiently attention on the physique and the dancer training and the medical care and the movement damage; The development of functional exercises is current tendency, but has the certain difficulty, the main reason is the equipment is insufficient, generally the investment of aerobics major course is insufficient;Curriculum study is difference, the skill study is few, cannot satisfy the demand to cultivate specialist; The teaching appraisal system is not science, mainly take the end test as the major targets or quotas, pay more attention to technical inspection, neglect its synthesis influence to the students' physical and psychological quality, cann't utilize self-comment, the other comments, mutually comments.

通过对具有代表性的26所高校的现行教学大纲的资料分析、调查发现，目前体育育专业健美操课程存在的不足主要体现在：课程目标定位不完善，忽视技能培养；课程内容参差不齐，不够重视形体与舞姿训练、卫生保健与运动损伤知识；拓展功能健身操是当前的一大发展趋势，但是存在一定的困难，主要原因是场地器材不足，普遍存在着对健美操课程的投资力度不够的现象；课程的学时比例差异大，技能学时偏少，不能满足培养人才的需求；教学评价体系不够科学，主要以终结性考试为主要指标，忽视评价诊断特性和过程性，没有将自评、他评、互评综合运用。

This study analyses and studies body shape and technical index of university students basketball athletes of China and USA. Conclusion; Body height and body weight of American sportsman is very different from that of Chinese sportsman; Body height of sportswoman is about the same; Compared with athletes in USA, the age of Chinese athletes is older than that of American athletes; In terms of such indexes as 3-FT-PCT, Assistant, Tumovers, Blocks, Dunk, Chinese and American athletes differ greatly each other;...

本文对中美优秀大学生篮球运动员的身体形态及 8项技术统计指标进行对比分析，主要结论：中美男子运动员身高、体重存在显著性差异；女子运动员身高差异不显著；与美国相比，中国大学生运动员的年龄普遍偏大；在三分投篮命中率、罚球命中率、助攻、失误、盖帽、扣篮等 6项技术指标上中美运动员存在显著性差异；平均每场得分、总投篮命中率等指标差异不显著。

But its limitation of invasive technique and high cost made the noninvasive and low cost brachioankle pulse wave velocity became a new possible predictor of ventricular arrhythmias on patient under hemodialysis. But no study had been done for the correlation of baPWV and ventricular arrhythmias directively on the patients under hemodialysis.

Of 11 cases of edema had diffusive uneven SCC lesions. 1 case of edema had single midline oval lesion of splenium. The brain lesions of edema were incontinuous. In follow-up MRI of 5 cases of brain edema, the lesions were disappeared. In 3 cases of cerebral infarct, the lesions of SCC and brain were lateral distribution. 2 cases of hemorrhagic disease had diffusive uneven lesions in SCC and ventricle.

水肿性病变(n=11)中10例MRI表现为SCC弥漫不均匀病灶、1例为居中类圆形病灶，颅内病灶呈跳跃不对称分布，5例MRI复查病灶消失。3例脑梗塞SCC及脑内病灶呈偏侧分布，脑内散在病灶以患侧较多。2例SCC出血，SCC病灶弥漫不均匀，并见脑室内出血。

Lacunar infarction in patients with hypertension is also common cerebrovascular disease, clinical manifestations of light, many people without clinical symptoms, and in nuclear magnetic resonance, CT examination or autopsy, was found when more specific clinical symptoms are: a simple movement obstacles, mild hemiplegia, aphasia or without sensory disturbance; pure sensory disturbance, migraine paresthesia or loss of body; dysphonia - clumsy hand syndrome, manifested as paresis and paralysis of tongue, speaking clearly, swallowing difficulties, fine motor hand and foot less flexible; ataxia and hemiparesis, inability to break limbs and lower limbs than upper limbs, uncoordinated movements, these symptoms often disappear in two weeks.

腔隙性脑梗塞也是高血压患者中常见的脑血管病，临床表现较轻，很多人无临床症状，而在核磁共振，CT检查或尸体解剖时才被发现，较为特殊的临床症状有：单纯运动障碍、轻度偏瘫，不伴失语或感觉障碍；单纯感觉障碍、偏身感觉异常或丧失；发音障碍-手笨拙综合征，表现为轻瘫和舌瘫、说话不清、吞咽困难、手脚精细运动欠灵活；共济失调性轻偏瘫，肢休无力、下肢重于上肢，运动不协调，这些症状常可在2周内消失。
