Results The primary ultrasound findings of cyst of the round ligament of the uterus were a regularshaped, smoothly thin-walled, and acoustic well-transmitted, nonechoic lesion, which did not diminish when probe press or in supi...

结果腹股沟区显示形态规则、壁薄光滑、透声良好的无回声包块，探头加压或平卧位后病灶不能回纳或缩小者为子宫圆韧带囊肿的主要声像图表现特征。

Based on the finite element method, a fresh and unique type of footbridge, a papilionaceous partial tied arch footbridge, was analyzed. The influences to the whole structure's stress behavior, displacements, vibration periods and mode shapes under parabola and arc arch axis were discussed. Different selections of support forms, such as longitudinal slide or longitudinal hinge, led to different behaviors on structure.

针对一种新型而特殊的蝶式部分系杆拱步行桥，基于有限元数值分析比较抛物线形拱轴线和圆弧形拱轴线对整个结构受力、变形、周期和振型的影响，揭示选用纵向滑动支座与纵向不动铰支座时给结构性能带来的不同结果，对结构拉索张拉力的控制给出建议。

On the other hand, there is Goriborg, a robot built by Dr. Penk and invades the earth under Dr. Penk's command. Goriborg should have been a Super Robot, but it does not function as properly as expected.

口诉。。。要折的漂亮还真是难阿~教学步骤非常一目了然，哪一个部份该压扁跟圆滚都说的很清楚，哈哈~可是做出来的时候，完全不是那回事阿！

A: A single negative stool examination does not exclude a parasitic infection, since the sample may have been collected during the prepatent period (i.e., the time between infection and the production of detectable ova or larvae) or because the target organism may have been shed inconsistently or in low numbers, as is frequently the case with strongyloides larvae.

一次大便虫卵和寄生虫检查的阴性结果不能排除寄生虫感染，因为样本可能在潜伏期还暂时没有异常（如在感染和产生可以检测到的虫卵或幼体前）或者所关注的微生物已经排出，或者数量太少，如类圆线虫属。

With rotational invariance of circle, image was divided into different sectorial sub blocks in polar coordinates, and the sum of regional pixels was taken as sector eigenvalue. Then a normalized feature space by norming sector feature set was got.

以圆的旋转不变特性为基础，在极坐标下将图像分割为不同的扇形子块，并将各子块区域灰度和作为表示扇形子块的特征，然后对子块特征集进行归一化，所得的归一化扇形特征集作为特征选取的空间。

The margin of the white matter tract become more clearly with the increasing of the number of gradient encoding directions, especially the detail of the brain stem. But the measured FA of the centrum semiovale, genu and splenium of corpous callosum, the internal capsule, thalamus and the pons with 6, 13 and 21 diffusion gradient encoding directions showed no statically difference.

随着弥散梯度编码方向的增加，FA图质量提高，对白质纤维束细节的显示也更清楚，尤其是对脑干结构的分辨，但成像时间延长；3种不同弥散梯度编码方向的DTI扫描方案所观察到的半卵圆中心、胼胝体膝部、胼胝体压部、内囊、丘脑及桥脑的FA值不存在统计学显著性差异。

Tapping screws may be tested using pre-threaded holes in test plates to achieve screw failures instead of thread strippage.

自攻螺钉应装入带有螺纹孔的试验圆板上拧至螺钉损坏，而不是在螺纹测试条上进行。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
