Any of various parasitic and nonparasitic worms of the phylum Platyhelminthes, such as a tapeworm or a planarian, characteristically having a soft, flat, bilaterally symmetrical body and no body cavity.

扁虫扁形动物门的寄生或非寄生虫中的任一种，以具有柔软、扁平且两面对称的身体和无体腔为特征，如绦虫或涡虫

Having no evident sex or sex organs;sexless.

无性的无明显性特征或性器官的；无性的不适合

The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

绿泥阳起石片岩的原岩主要为富含玄武岩的火山－沉积岩系，绿泥阳起石片岩和蚀变枕状玄武岩具有TiO2、P2O5、MgO含量较高和LREE富集型、无Eu异常，以及"大隆起"微量元素配分模式和富集Nb、Ta、Ti元素等地球化学特征，显示为较典型的洋岛型碱性玄武岩性质。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

As a result, the statistic feature of measurement error becomes different,and the derived rheological parameter estimation tends to be no unbiasedness and with the least variance.

钻井液流变模式的参数估计问题大多使用线性回归方法求解，然而，线性回归方法改变了测量误差的统计特征，使得所得到的流变参数估计不具有无偏性和方差最小等特点。

Unlike unbiasedness―which is a feature of an estimator for a given sample size―consistency involves the behavior of the sampling distribution of the estimator as the sample size n gets large.

无偏性是，给定样本容量n下，估计量的性质；一致性则是，当样本容量n变大时，估计量的样本分布的变化特征。

Surprisingly, now the speaker has quietly explode (mainly supply of inventory and personal collection), worth surge in, 2.5-inch uvula spring actually sold more than 200 yuan a speaker (with value-free city, and that it is another matter a), that not it has a new function, but the way people see it as an era is characterized by the desire to hold.

谁知现在这种喇叭又悄悄地火爆起来（货源主要是库存及个人收藏），身价激增，2.5寸的小舌簧喇叭居然卖到二百多元一只（有价无市那又是另外一回事了），到并不是它又有了新的功用，而是人们把它看成是一个时代的特征而渴望持有。

The results suggest the expression of Nm23-〓 Protein is more often seen in the cases of adenosis with atypical hyperplasia than in the cases of carcinoma, the expression of Nm23-〓 might be a marker of adenosis with atypical hyperplasia in cases of FCD; Lower level of Nm23-〓 suggests in had a high metastatic potentiality in breast cancer.

在浸润性导管癌组中，有腋窝淋巴结转移组的Nm23-〓含量显著低于无液窝淋巴结转移组。结果提示：Nm23-〓蛋白在不典型增生上皮中的表达比癌组织更常见，Nm23-〓蛋白过度表达可能是乳腺上皮不典型增生的一个特征；在乳腺癌病例中，Nm23-〓蛋白表达与腋窝淋巴结状态有关。

The CT and MRI manifestations of pachygyria and agyria are presented with a review of the pathological features of the disorders and an evaluation of the diagnostic value of both imaging modalities.

结合巨脑回和无脑回畸形的病理特点，研究两种病变的 CT、MRI表现特征，以评价两种影像学检查方法该病变的诊断价值。

And according to the directions, the Bandelet blocks were classified into two sorts: the Bandelet blocks with geometrical directions and the Bandelet blocks without geometrical directions, and the different characteristics of the two sorts of Bandelet blocks were analyzed in order to distinguish the noise and signal, and the weak contrast features and the strong contrast features.

根据图像增强方向将Bandelet块分为两类：有几何方向的Bandelet块和无几何方向的Bandelet块，并分析了这两类Bandelet块系数的不同特征，从而区分出噪声和信号、清晰边缘和脆弱边缘。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
