Through the experiment results, in different phonation model, analysis the properties of glottal vocal efficiency, vocal folds vibration, and voice source.

我们在对嗓音—呼吸系统进行自动分割与分段特征表达的目标指引下，建立了具有国内一流水平的嗓音声学实验室；从概念上对嗓音—呼吸系统重新划分，以声门为中心分别建立去耦合和弱耦合条件下的嗓音—呼吸系统和肺胸系统数学模型；采用离体犬喉作为声带振动的物理模型，对数学模型进行完善与证实；采用盲解卷技术在去耦合和弱耦合条件下，提取上下声道传递函数、嗓音源和发声效率，研究上下声道去耦合和弱耦合条件下不同发声方式与状态对发声效率的影响。

With fluctuant territory and natural vegetation and beautiful environment,it will be developed into the international conference and tourism spot that integrates hotel,conference center,sports,recuperation,catering,recreation and commerce,it is composed of the low-density residential buildings and holidaymaking and resort villages with complete facilities ,such as hotel,six major centers,golf court,primary school,middle school and kindergarten.

项目地势起伏，自然山体植被丰富，环境优美，将建设为集酒店、会议、运动、康体、饮食、娱乐与商业于一体的国际会议旅游度假区。规划有低密度住宅、洋房等度假居住型物业，配套酒店、六大中心，高尔夫体育设施、中学、小学、幼儿园及其他商业设施。

Result The coincident rate and the incoincident rate were 63.23%(group A, 98 hips) and 36.77%(group B, 57 hips) respectively. For loose, dislocation or low back pain, the rate of revision in group A and group B were 6.12% and 29.82% respectively.

结果］旋转中心恢复者98髋(63.23%)，未恢复者57髋(36.77%)；A、B两组中因人工髋关节松动、脱位、髋部痛等行髋关节假体翻修术分别为6髋(6.12%)、17髋(29.82%)。

结果旋转中心恢复者98髋(63.23%)，未恢复者57髋(36.77%)；A、B两组中因人工髋关节松动、脱位、髋部痛等行髋关节假体翻修术分别为6髋(6.12%)、17髋(29.82%)。

As the novel design of the fusion apparatus improves the mechanical strength of fixation of STT and prevents the possible rotation and collapse of fused STT, the apparatus is a reliable internal fixation device for the limited intercarpal arthrodesis.

STT融合器设计合理，它可使3块腕骨间的固定力学强度大大提高，并可防止STT融介体向关节中心旋转及塌陷，是局限性腕骨融合术中新型、可靠的内固定方式。

The meshwork results are obtained from the later pictures. They clearly show the structure of four-dimension reseau and some meshwork results of shell data. The reason why the whole results are not achieved is that there are too many circumstances in which five or more dots share the same orb. In this case, the principle Delaunay is not in point any more, then the process of establishing meshwork will be intermitted.

后面的4幅图是后来所作的工作，得到了1个正方体4顶点以及其中心点的建网结果，从这里能清楚地看到4面体网格的结构，还有对贝壳数据点云的部分建网结果，之所以没有完成整个贝壳数据的建网是因为数据中存在较多的5点或5点以上共球的情况，这种情况下Delaunay准则不再适用，建网会中断，所以只完成了1个部分。

For efficient planning of large and irregular shaped tumors with KULA, it is essential to be familiar with the principle of allocation and methods of fine adjustment of parameters of shots.

虽然经过多次的修正后仍能得到满意意的剂量分布，但所费的时闻相当不经济。在新一代的治疗计画软体尚未启用前，熟悉KULA系统的特性及聚焦中心的配置组合原则，是进行高效率治疗计画的唯一途径。

The granitic enclaves in the central-facies porphyroblastic lava are subvolcanic rocks with forming age of 134.2±1.9Ma. There is another intrusion of subvolcanic rhyodacitic porphyry with age of 136.0±2.6Ma, in the contact zone of the two volcanic cycles in the western part of the Xiangshan complex. The U-Pb ages of the sub-quartz-monzonite porphyry and lamprophyre are 129.5±2.0Ma and 125.1±3.1Ma, respectively. This suggests that the extension in the Xiangshan region, began in K〓, was week, and earlier than that in the coastal region of Zhejiang and Fujian provinces. Extension in K〓 in Xiangshan and neighboring regions was much stronger, forming NE striking large red-downfaulted-basins.

相山中心相碎斑熔岩中的花岗质包体属次火山岩，其成岩年龄为134.2±1.9Ma，在相山西部两火山旋回的界面之间，存在另一类次火山岩的侵位，其成岩年龄为136.0±2.6Ma，岩性为次流纹英安斑岩；次石英二长斑岩及煌斑岩的成岩年龄分别为129.5±2.0Ma及125.1±3.1Ma，说明相山地区的伸展、裂解作用明显早于浙、闽沿海，在K〓就开始了，但规模并不是很大；而K〓时期的拉张作用在相山及其邻区表现的更为强烈，形成了大面积的呈北东向展布的红色断陷盆地。

Still others simply lateralize the hip center without reorienting its opening face Fig.

还有一些假体仅单纯外移髋关节中心，而不改变其开口面的方向（图7－39）。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
