单腔的

Finite-difference time-domain method was used to simulate the coupling processes of ultra-wide-band electromagnetic pulses into a cavity with a slot, and an anisotropic perfectly matched layer absorbing medium was inserted to truncate the computational lattices.

用时域有限差分法模拟超宽带脉冲入射时与目标腔体上的孔缝相耦合的过程，用单轴各向异性的完全匹配层吸收边界条件截断时域有限差分网格。

Results: In the 23 cases of disease group, 16 cases were unilateral and 7 cases were bilateral. X-ray examination showed local prominence between ischium and pubis in all cases. Lamellar changes of the bone inhomogeneous in density with round translucence were found in 8 cases accompanied with intact cortex. Mild osseous hyperplasia was found in 8 cases without changes of periosteum and soft tissues. CT examination of 8 cases presented with local prominence between iscbium and pubis, translucence, cataclasm, discontiguous osteal cortex with irregular ends, sclerotic medullary cavity of honey surroundings, but no sequestration and changes of periosteum and soft tissues. The above-mentiooed X-ray features appeared in 14 cases among normal group, bilateral in 3 cases.

结果：病变组23例中，16例为单侧，7例为双侧。X线表现为坐骨耻骨结合处局限性骨膨隆，8例有层状改变，病变区内密度不均，有类圆形低密度透光影，骨皮质完整，8例周围骨质轻度增生，未见骨膜反应和软组织改变。8例CT表现为坐骨耻骨结合处局部膨大，其内有低密度透光区，有碎裂，骨皮质连续性中断，断端边缘欠整齐，邻近的髓腔轻度硬化，无明显的死骨和骨膜反应，邻近的软组织正常；正常组中14例出现上述X线改变，其中3例为双侧性。

Through valve: A valve with a linear movement of the closure components, there is a single seat or multi-seat, and its valve seat area because there is a spherical cavity and different.

直通阀：一种阀门，带线性运动的截流元件，有单阀座或多阀座，它的阀体因为阀座区域有一个球形的内腔而与众不同。

We also calculate the spectra of the cavity field numerically via the eigenvalues and the eigenvectors of the mazer master equation for the case with the number of atoms from one to four.

通过求解主方程系数矩阵的本征值与本征矢，我们计算了入射原子团中包含一到四个原子时腔场的光谱与平均光子数，其中着重对单原子与二原子的数值结果作了讨论。

Further, the mapping function from the simply connected region of flat-plate to the unit circle is acquired, and based on this, the mathematical representation of transitional surface is established.

最终，构造壁板外形单连通域到单位圆周的映射函数，并以此建立壁板挤压模型腔曲面数学方程，利用三维造型软件完成了复杂型材挤压"流线型"过渡曲面的三维建模。

Its shunt impedance is three times higher than former single gap bunchers used by TUM and the length of the buncher system is one fifth of former one only because the use of λ/4 coaxial cavities with double gaps.

由于采用了双间隙型λ/4同轴腔结构，分路阻抗是慕尼黑以前所用的单间隙型的4倍，而聚束系统占用的束线长度缩短到20 %。

Objective: To explore the renal damage effect of flushing Sodium Chloride into pelvis unilaterally at constant intrapelvic pressure, and provide a theory basis for clinical practice for the treat of upper urinary tract diseases by endoscope.

目的：研究兔单侧输尿管逆行恒压灌注后对肾脏的影响，为临床评价内腔镜操作所致肾脏的改变提供理论依据。

Results Fibroblast ceils were divided into three groups, and cell proliferation was inhibited in the low-dose group, but promoted in the middle-dose group, while the collagen synthesis was inhibited in the middle-dose group, but pro- moted in the high-dose group.

结果激光照射剂量由低至高可分为3个剂量段，激光强度在第一剂量段时的生物调节效应主要表现为抑制细胞增殖，在第二剂黾段时则能促进细胞增殖并抑制胶原合成，在第三剂量段时间则可促进腔原合成，且每个剂量段内的激光生物调节效应与照射剂量间大致单线性相关。

Methods: An animal model of Low pressure of upper airway was proposed by use of the little type pig, and the tension-stretch ratio relationships of the pharyngeal soft tissues such as cavum nasopharyngeum, soft palate and staphylion were measured in vitro through uniaxial tensile experiments.

用小型猪建立上气道低阻力动物模型来模拟阻塞性睡眠呼吸暂停综合征症状，对动物模型的咽组织（包括鼻咽腔软组织、软腭和悬雍垂）进行单轴拉伸实验，离体检测各部分的弹性，并和正常情形进行对比。

Stems unarmed, sometimes with conspicuous lenticels, or bark sometimes shredding; branches often swollen at 3-7-lacunar nodes; pith continuous or interrupted by diaphragms at nodes; tendrils simple, bifurcate to trifurcate, or 4-12-branched, usually leaf-opposed, rarely tendrils absent.

茎无刺，有时有明显的皮孔，或者树皮有时碎片状（在大多数葡萄属的种里；分枝通常在3-7节腔隙膨胀；髓连续或在节上被膈膜间断；卷须单，二叉对三叉，或者4-12分枝(在Parthenocissus)，通常对生，很少无卷须。
