Methods. A 60-year-old man with athetoid cerebral palsy and a history of posterior occipitocerical fusion presented with quadriparesis. Salage surgery for cerical myelopathy and pseudarthrosis was performed with laminectomy and rearthrodesis using the pedicle screw system. An intraspinal cyst was identified as the main cause of the paraparesis.

一位60岁的手足徐动症样大脑麻痹患者，既往曾行后路枕颈融合术，临床表现为四肢轻瘫，影像学检查示脊髓型颈椎病和假关节形成，采用椎板切除和椎弓根钉系统关节成形术后，发现椎管内存在的囊肿是导致四肢轻瘫的主要原因。

By using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [13] , [73] ); B-net form of bivariate splines function; discriminant sequence of polynomial (cf. [13] , [73] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite.

3：利用杨路，张景中，侯晓荣在文献（[13]，[73]）中关于一元多项式实根的显式判准，以及二元样条函数的B-网形式，多项式的判别序列和Sturm序列的最高次数项系数序列的变号数，本文给出了两个分片代数曲线的实交点数的计算公式。

And the polar angle and the polar radius was represented into AutoCAD polar coordinate, the involute was drawn through the spline linear tool. And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting.

根据DIN 3960渐开线花键的坐标值，用EXCEL函数功能计算出不同压力角下渐开线的极角和极半径，表示成AutoCAD极坐标并通过样条线工具绘制出渐开线，再用齿顶圆和齿根圆直径截取一段渐开线作为为花键齿面，并用分度圆直径绘制出渐开线齿剖面，经镜像和裁剪便可绘制出渐开线齿形。

We X- rayed the lighter using Morgan's method, which showed the base to be hollow, containing several small items

我们用摩根的方法对打火机作了X光透视，发现其底部是空的，里面装了几样小东西。

The proliferation effect of eight extracts of four Urtica plants on clone MC3T3-E1 cells was examined with cell counting kit-8 (CCK-8) and alkaline phosphatase activity was also determined.

结果三角叶荨麻根的醇提物，宽叶荨麻全草的醇提物和醇提物水层过D101大孔树脂40%洗脱部分在50到200 μg/ml 的浓度下能显著促进成骨样细胞MC3T3-E1增殖。

Bear in mind also that to the lover the loved one is always the most beautiful thing imaginable, even though to a stranger she may be indistinguishable from an order of smelts.

还要切记：在恋人眼中被爱的那位总是想象得出的最美的尤物，即使在陌生人看来她其貌不扬，跟一根胡瓜没什么两样。

After transplanted in nude mouse for 8 weeks, DAC-MSCs can regenerate cementum-like structures and dentin-like structures. At the same time, we used limiting dilution assay to screen monoclonal cells from DAC-MSCs and discovered two kinds of phenotype cells: one is osteogenesis type, and the other is fibro singtype.

结果显示：牙根发育期根尖复合体来源间充质干细胞为异质性；具有显著的&胚胎性&组织特征：表现出极高的增殖活性、克隆形成能力和体外多向分化能力；在体内可以异位形成类牙骨质和类牙本质样矿化结构。

The columns exhibited good separation ability for disubstituted benzene isomers, especially for xylenes and cresols. In addition, the three peralkylated-β-CD columns offer better selectivity than the (2,6-di-O-benzyl)-β-CD column.

同一根柱不同次进样和不同柱之间表现出良好的重复性，保留时间的相对标准偏差小于8.5%；对使用大约40次后的溶胶-凝胶柱重新进行测试，柱效下降不明显，说明该类色谱柱的稳定性良好。

Focusing on all these functional traits, 13 functional groups were identified by TWINSPAN (two-way indicator species analysis), and their change with different environmental factors, disturbance types and recovery time was ordinated by DCCA(detrended canonical correspondence analysis).

本文以海南岛霸王岭林区作为海南岛热带林的典型区域，以反映不同环境因子、干扰类型和恢复时间的热带山地雨林为研究对象，在大面积(15hm~2)样地调查的基础上，依据物种的7个功能特性(喜光性、潜在高度、板根大小、木材密度、种子生物量、传播方式和落叶／常绿性)，分别把物种划分为不同类别的功能群，应用NMS分析了各功能群随不同干扰类型和恢复时间热带山地雨林群落的变化规律。
