In 1970s, boundary value problems with equivalued surface are put forward. Andit is important to study them to solve practical problems. Li Ta-tsien and his partnersdo systematic research on them, especially study certain kind of elliptic boundary valueproblem with equivalued surface on the domain with thin layer.

Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.

试验分析表明,大锥段和小锥段切向速度分布规律基本相同,均由准自由涡和准强制涡构成,分界面半径rm没有变化;随着小锥角θ的增加,准自由涡区缩小,准强制涡区扩大,速度梯度增加会加大液滴的乳化程度;随入口流量增加,切向速度增大,经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍;分流比加大,分界面半径基本不变,最大切向速度增加。

考虑实用性和合理性,将线元看成离散点的集合,将线的不确定性看成点的不确定性的聚合体,将线元的位置不确定性模型看成以各点误差椭圆的长半轴E为半径的误差圆的聚合体,建立了以线元上任意点处的误差椭圆的长半轴E为带宽的线元不确定性ε模型。

In this thesis, we propose a self-detecting algorithm for the nodes of a wireless sensor network to determine the event boundary in the presence of faulty nodes. The nodes exchange messages and execute the algorithm in parallel to determine whether they are located on the boundary of an event.

在这篇论文中,主要的目的是在一个无线感测网路环境下,如果当事件发生时,每一个感测节点如何透过单纯的资料交换和平行演算法来达到自我侦测并且判断出本身是否位於事件的边缘。

On the basis of the above references, this paper attempts to make use of cone compression and expansion fixed point theorem, Mnch fixed point theorem and fixed point index theorem to discuss a special kind of singular boundary value problem-Lidstone boundary value problem.

Primary atrial tumor has obvious characteristic on RT-3DE: All the atrial tumor display the same size of stereoimages as the tumor themselves. There is a clear boundary between the stereoimage of the myxoma and the atrial wall and there exists a short pedicle connecting the atrial myxoma to the atrial wall or the interatrial septum. The body of the atrial myxoma moves to and fro through the atrium and the atrioventricular valve with the contraction and relaxation of the heart with a fixative pedicle. Atrial myxoma leads to relative atrioventricular valve incompetence during systolic phase and relative atrioventricular valve stenosis during diastolic phase, but doesn't result in pathological changes of atrioventricular valve which restore to normal after exsection of the atrial myxoma. Malignant atrial tumor closely and extensively contact with atrial wall without obvious boundary, pedicle and movement with the contraction and relaxation of the heart.

所有心房肿瘤RT-3DE均实时显示与肿瘤大小相同的立体形态图像;心房黏液瘤立体形态图像与心房壁界限明显,都通过一短蒂与房间隔或心房壁相连,瘤体以蒂为固定点随心脏收缩、舒张在心房与房室瓣口之间往返运动;心房黏液瘤收缩期瘤体导致房室瓣相对关闭不全,舒张期瘤体导致房室瓣相对狭窄,但瘤体不引起房室瓣器质性病变,瘤体摘除后房室瓣功能即恢复正常;恶性心房肺瘤立体形态图像与心房壁关系密切,界限不明显,接触范围广泛,无蒂,瘤体不随心脏收缩、舒张运动。
