多表现

ABSTRACT: Primary carcinoma of the gallbladder is the most common malignant tumor in biliary system and its morbility has been rising year by year in our country.

由于原发性胆囊癌无特异性的临床表现，临床发现的胆囊癌多属中晚期，根治性切除率低，预后差。

Na$_{0.5}$Bi$_{0.5}$$_{1-x}$Ba$_{x}$TiO$_{3}$ ceramics with the compositions near the morphotropic phase boundary show superior piezoelectric properties due to the existence of more spontaneous polarization directions.

在准同质相界附近的组分存在较多的自发极化取向，因而表现出优良的压电性能。

Herein, we report an unusual case with profuse watery sputum and multilobar consolidation on the chest radiography.

我们在这个报告中提出一个罕见的病例是以大量水状的支气管漏及胸部X光多肺叶实质病变来表现并快速进展成严重的缺氧性呼吸衰竭。

A case of endosalpingiosis presented as a multilobular cyst on sonography.

本文报导一例在超音波下以多囊性瘤表现之子宫浆膜的endosalpingiosis。

These masses showed slight to marked lobulation(15/21), and although some are smoothly bordered, but others exhibited a spiculated margin. Less commonly, they included multilobulated masses, a thin-walled cavity, lobar atelectasis without demonstrable mass.

这些肿块可表现出浅分叶（15/21），尽管其中一些边界光滑，大多边界可呈毛刺状，还包括多室性的肿块，薄壁空洞和没有明确肿块的肺不张。

Objective:To explore the imaging features of multilocular cystic renal cell carcinoma and diagnostic value of CT.

目的：探讨多房性囊性肾细胞癌的CT表现特点及诊断价值。

Objective: To explore the dynamic SCT findings of multilocular cystic renal cell carcinoma and evaluating its clinical value.

目的：分析多房囊性肾细胞癌影像学表现，以提高其诊断准确性。

Methods The information of 4 cases of multilocular cystic nephroma were retrospectively and analyzed,Discussion the Diagnostic value and Ultrasonography of multilocular cystic nephroma.

回顾性分析4例多房性囊性肾瘤患者的超声资料，结合文献讨论本病的超声表现及诊断价值。

Results Multiple little cystic mutation area and multilocular cyst are the characteristic imageology appearance of USL.

结果多发性小囊状突变区或多房性囊性肿块为肝未分化肉瘤影像学较特征性表现。

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

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。
