In practice, the earth is a non-rolling-symmetry ellipsoid, so much as is an ellipsoid as a pear.

In our algorithm, an error-based ellipsoidal merge algorithm and avariational ellipsoid optimization algorithm are designed.

在椭球体树构造算法中，设计了基于误差控制的椭球体合并算法和变分椭球体优化算法。

Constructed by standard binary classes support vector machine, present multiclass SVMs are usually very slow to be trained. When a large number of categories of data are to be classified, the training work could be very difficult. By extending the hypersphere one-class SVM to a hypersphere multiclass SVM, we build a fast training classifier HSOC-SVM. Its training speed is higher than that of the present multiclass classifiers, because each category data trains only one HSOC-SVM.

目前的多类分类器大多是经二分类器组合而成的，存在训练速度较慢的问题，在分类类别多的时候，会遇到很大困难，超球体多类支持向量机将超球体单类支持向量机扩展到多类问题，由于每类样本只参与一个超球体支持向量机的训练，因此，这是一种直接多类分类器，训练效率明显提高。

Methods Two mathematical models were created for preoperative planning of the ablation in spherical tumors. The models were based on the overlapping sphere principle and were deduced and calculated by the regular prism way and regular polyhedron way.

将肿瘤模式化为类球体，根据球体覆盖原理建立数学模型，应用正棱柱法及正多面体法进行推导计算，获得治疗范围与射频针伞径、布针次数的关系式。

The formulation for the contact force between two spheres and the stress and displacement which is caused because of the contact force is also derived. The calculation method of the contact of sphere and plane, sphere and tee is given .At the same time, the formulation for the force distribution of the contact surface is established on the discussion of two arbitary elastomer's contact.

第二章以《弹性力学》理论为基础，详细地介绍了接触单元理论，导出了两个球体之间的接触压力及由此引起的应力和变形，给出了球体与平面相接触、球体与球座相接触的计算方法，同时，对于两任意弹性体接触的讨论，得到了接触面上压力分布的公式。

It is incompatible compared with modern streamline artistic frame.The innovation spherical adjustment stem change the turning point above the headset and intergraded with headset cap covered by spherical structure.

创新球体调整角度立管，改以车头碗组处上端为基准点整合了碗组盖及包覆性球体结构，配合双向轨道齿状的咬合设计，达到60度调整范围。

The Earth possibly is one by occupies the major part material stably the counter-flow inner layer as well as occupies the few parts the counter-flow outer layer to be composed, the former is constitutes the Earth quite stable movement, the attraction, the magnetic field and so on the macroscopic phenomenon foundation; The latter constitutes the Earth most to be rich in the change the beautiful semblance, such as: Land, islands, volcano, earthquake, plate movement and so on nature environment with each kind of great phenomenon, eliminate this this also are decide the Earth for the perfectly round spheroid basic reason, because the internal heat circular reactions is from starts, the huge energy finally becomes the Earth good fortune a beautiful rich life the star.

地球可能是一个由较稳定占绝大部分物质的对流内层以及占较少部分的对流外层组成，前者是构成地球比较稳定的运动、引力、磁场等宏观现象的基础；后者则构成地球最富于变化的美丽外表，诸如：陆地、岛屿、火山、地震、板块运动等等自然界环境与各种伟大的现象，除此这也是决定地球为浑圆球体的根本原因，因为内热循环反应是从一点开始的，巨大的能量最终把地球造化成一颗美丽的富有生命的星球。

Excied root apex explants of seedlings from Mormodes Jumbo Odin × Catasetum expensum were induced to from PLBs in MS medium supplemented with BA (0.5 mg/l ). Histological observations confirmed that root cap were disorganized at early stage and followed by vascular strand of existing roots protruding into PLBs formation.

以不同时期的根类原球体为材料经石蜡切片后发现，早期会先在根尖端形成球状突出，随著根类原球体膨大，根培植体的维管束延伸到球体之中并支撑著尖端形成芽原基，而后根类原球体顶芽长出维管束成为植株。

According to the fluorescence real-time quantitative PCR test, EGFR expression amount was higher in glioma cell line spheroids and glioma stem cellular spheroids, but lower in neural stem cellular spheroids, which was consistent with the results of protein level determination.

荧光实时定量PCR检测显示EGFR mRNA在人脑胶质瘤体外细胞系球体及脑肿瘤干细胞球体中表达含量高，在神经干细胞球体中表达含量极低，与芯片中蛋白水平的检测相一致。

While the Addis hypothesis of work hypertrophy to excrete urea is erroneous, a more modern concept associated with glomerular hyperfiltration was proposed in the 1980s by Brenner.25 This hypothesis states that after any significant loss of renal function, surviving nephrons subsequently undergo functional and structural changes including increases in single nephron GFR and glomerular capillary pressure increases.

当Addis成果假设过度膨胀分泌尿素的观点是不正确的，Brenner在1980年代提出了有关肾丝球体高滤过率的最新观点25。这个前提陈述，在肾脏功能有任何显著的丧失之后，幸存的肾脏小过滤器也接著经历了机能上和构造上的改变，包含增加了一单位小过滤器的肾脏丝球体过滤率和提高肾丝球体毛细管压。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
