The features seen were (1) small-bowel obstruction as evidenced by dilated hyperperistaltic loops,(2) a zone of transition between the dilated and nondilated bowel, and (3) a cluster of collapsed, crowded, and compressed small-bowel loops, as if enclosed in a bag.

这里我们报道了4例腹内疝的超声表现，其中3例的表现一致，这3例中包括1例十二指肠旁疝和2例盲肠旁疝，所见特征有：（1）小肠梗阻，表现为肠管扩张，蠕动增强；（2）扩张和非扩张肠管间有过渡区；（3）小肠堆积成团并受压，好像是被袋子包裹着一样。

2Compared with PN group,following microcirculatory changes were observed in EEN group in vivo status:interlobular artery and vein structures disappeared,the vessel course was distorted and deformed;intralobular vessels were twisted into nidus,there was patchy bleeding around the vessel combined with necrosis;microcirculatory structures of pancreatic island disappeared and pancreatic tissue necrotized;capillary network had bleeding and necrosis.

2活体状态下观测大鼠胰腺微循环情况显示与PN组相比，接受EEN治疗大鼠急性胰腺炎微循环小叶间动、静脉伴行结构消失，血管走行扭曲变形更加明显；小叶内血管扭曲变形成团，血管周围出现斑片状出血，并伴有坏死；胰岛微循环结构消失，组织坏死；毛细血管网大片状出血、坏死。

Results In define induction envioroment, HPMSCS can diferentiate into lipoblast、after 2 weeks, the induced cells are full of lipid droplet;HPMSCS can differentiate into osteoblasts, after 4 weeks, we can see calcified tubercle in the cells, calcium in the calcified tubercle can be dyed black by Von Kossa and ALP dying is positive reaction above 95%.

结果 HPMSCS在培养基中持续培养后，在特定诱导环境下，成功使其向成脂肪细胞转化，培养2周时，可见融合成团的脂滴充满整个细胞；成功使其向成骨细胞转化，培养4周以上可见明显钙化结节，von Kossa染色可将骨结节中沉积的钙染成黑色，碱性磷酸酶染色呈强阳性反应达到95%以上。

Endocervical cells are present, indicating that the transformation zone has been sampled (a minimum of 10 well-preserved endocervical or metaplastic cells is required; they do not have to be in groups).

颈管内膜细胞存在，提示子宫颈上皮移形带细胞已经被取样(至少有10个保存良好的颈管内膜细胞或化生细胞所必需的；但不需要成团排列)。

Sometimes the muscle is not attached directly to the bone but to a tough, nonstretchable cord, or tendon, that is attached to the bone.

肌肉在收缩的同时，也会聚成团。肌肉以条状或片状形式布满全身，存在于皮肤与骨架之间。

The ARFGAP3 is a cytosolic protein and concentrated mainly in the perinuclear region when it is overexpressed in mammalian cells.

ARFGAP1分布于细胞质中，当表达量高时在核周聚集成团块状、颗粒状，并聚集在高尔基体上发挥功能。

When the embryo reached the prehatching stage, the hatching enzyme granules were secreted into the perivitelline space from the top of HGCs. Secretory granules were spherical and 0.5-1.0 μm in diameter. The hatching enzyme was dissolved in the perivitelline fluid, where it gained access to the egg envelope and digested the inner layer of the egg envelope.

至孵化前期时，孵化酶颗粒自HGCs顶部的开口分泌出来，分泌颗粒呈圆球形，直径为0.5-1.0 μm，有的以单体的形式存在，有的粘结成团。

The nano powder was then used to prepare dense HAp body by using pressureless sintering.

本实验致力於解决奈米粉成团的问题。

Transmission electron microscope results revealed vascular endothelial cells with normal morphology in the control group and tumor cells with apparent nucleoli in the Ad-GFP group, while in the Ad-aMMP-2 group, some vascular endothelial cells exhibited chromatin pycnosis in the nucleus, forming apoptotic bodies.

透射电镜观察对组血管内皮细胞形态正常；Ad-GFP组瘤细胞大，核仁明显；Ad-aMMP-2组部分血管内皮细胞核内染色质固缩，聚积成团块状形成凋亡小体。

In this paper,mechanism and influential factors of sodium silicofluoride caking were analyzed in detail.

随着时间的推移，这些晶体之间形成晶桥，使氟硅酸钠粘结在一起，逐渐形成团块

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。
