A new technique is presented in this paper for frequency estimation of single real sinusoid at a low computational cost using the real parts or imaginary parts of Fourier coefficient s.

提出了一种利用信号离散傅里叶变换系数的实部或虚部来构造频率修正项的新算法，算法只需傅里叶系数的实部或者虚部的最大值附近的3个DFT系数来构造频率修正项，避免了复数运算从而有效减少了运算量，同时算法的频率估计精度接近CRLB(Cramer-Raolow bound)。

The Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.

人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。

We detected that EGF mRNA was expressed sflungly lii the oocyte, and is also found hi gmnulosa cells, the cell fium smaller foflicular expressed stronger than fium bigger one. In the corpus hemonbaglcwn corpus luteurn, lean type and pseudocorpus-luteum, EGF rnRNA was detected,, no distinct difference can be seen in them. The EGF mRNA expressed strongly in fimbria end, ampulla and isthmus of oviduct, in the big follicular stage, ovulation stage, pregnancy stage and spurius pregnancy stage, we can not see any distinct change in them, but hi the medium follicuar stage,it is weaker.

结果发现：猪卵母细胞中EGF的mRNA强烈表达，且小卵泡卵母细胞→中卵泡卵母细胞→大卵泡卵母细胞中，EGF的mRNA表达量有逐渐减少的趋势；猪卵泡的颗粒细胞中有EGF的mRNA表达，小卵泡颗粒细胞→中卵泡颗粒细胞→大卵泡颗粒细胞中，EGF的mRNA表达也有逐渐减少的趋势；猪卵巢中的红体、黄体、白体和假黄体中都有EGF的mRNA表达，看不出几部分的表达量有明显的强弱变化；猪输卵管伞部、壶腹部和峡部，都有EGF的mRNA表达，在大卵泡期，排卵期，孕期和假孕期都强烈表达，各期间看不出明显的强弱变化，中卵泡期表达较弱；猪子宫中EGF的mRNA在大卵泡期，排卵期，孕期和假孕期都强烈表达，看不出表达量的明显变化，而小卵泡期表达量明显减弱。

Experts, the expansion of the chemical agent called motilin cells, hormones are chemical substances, commonly used fruits and vegetables have a kiwi, watermelon, strawberries, cherries, tomatoes, and some vegetable farmers in the cucumber, summer squash and other vegetables used in this way to make fruits and vegetables-cell non-normal enlargement, head of fruits and vegetables grown up than the normal 1-2 times as large, the shape become more exotic, such as tomatoes, long tip, strawberries were piriform, cucumber apex hypertrophy with pedicle sharp contrast and so on.

专家介绍，膨大剂的化学名称叫细胞集动素，属于激素类化学物质，常用的果蔬有猕猴桃、西瓜、草莓、樱桃、西红柿等，有些菜农在黄瓜、西葫芦等蔬菜上使用，以此方法使果蔬细胞非正常膨大，个头比正常长大的果蔬大1—2倍，形状变得比较奇特，如西红柿长尖、草莓呈梨状，黄瓜尖部肥大与蒂部形成鲜明对比等。

The result manifest that characteristic of chin soft tissue profile of bony malocclusion of class I had bigger angle of chin-lip, shallower mentolabial furrow,smaller radian and larger convexity compared to that of bony malocclusion of class II, and smaller angle of chin-lip, deeper mentolabial furrow,larger radian and smaller convexity compared to that of bony malocclusion of class III.

测量结果显示：骨性II类错牙合颏部相对于正常牙合发育不足，颏唇角小，颏唇沟深，弧度较大，突度较小。而骨性III类错牙合相对于正常牙合颏部发育过度，颏唇角大，颏唇沟浅，弧度较小，突度较大。
