As the graph of Bayesian network is required to be a directed acyclic graph, which was changed during the constructing process, checking for cycle is need in the interaction.

由于贝叶斯网的网络结构要求为一有向无环图，并且此图在交互建网过程中时刻变化，所以要在交互过程中反复检测环路是否存在。

Results: The most common locations of PIP were at the margin of both lower lobes and associated with local pleural thickening and adhesion. The density of nodule in which CT attenuation value was 15~60 HU (26.9±13.5HU) was lower than that of PLC. Most of them were round/round-like and irregular in shape. The interior density of lesion was inhomogeneous. The presence of calcification or multiple cavitations, straight margin sign, hole sign and without hilar and mediastinal adenopathy were of great significance in the diagnosis of such kind of disease.

结果：炎性假瘤多位于两肺下叶，邻近胸膜增厚、粘连，病灶密度偏低（平扫CT值15~60HU，平均26.9±13.5HU），与周围型肺癌比较有统计学差异，其形态以圆形／类圆形和不规则形多见，病灶内密度多不均匀，可见钙化及多发空洞，边缘呈平直状、周围见毛玻璃样改变及肺门纵隔无淋巴结肿大等征象对本病的CT诊断有意义。

The cones are globose to ovoid, 1.5-2.5 cm in diameter with 16-28 scales, arranged in opposite pairs in four rows, each pair at right angles to the adjacent pair; they mature in about 8-9 months after pollination.

叶交互对生，在绿色脱落的侧生小枝上排成羽状二列，线形，柔软，几无柄，通常长1.3一2厘米，宽1.5一2毫米，上面中脉凹下，下面沿中脉两侧有4－8条气孔线，雌雄同株。

These all show pronounced stratification. There are three kinds of neurons related to the optic lobes: amacrine cells, columnar neurons and tangential neurons, only a few of which are stained.

视叶包含三种神经元：无长突神经元、柱状神经元和切向神经元，其中只有少数被标记，与前脑间的神经通路呈弱阳性反应。

We administered a novel action comprehension test--with almost no linguistic requirements--on selected frontal aphasic patients lacking apraxic symptoms.

我们对无使用症状的选择性额叶失语症患者进行一项新型行为理解能力测试。

The average molecular mass of polysaccharide is 8.6×10^4 u. Polysaccharide is composed of glucose, arabinose and uronic acid. There is no absorption peak of protein and nucleic acid at 280 and 260 nm.

大叶金花草多糖平均分子质量为8.6×10^4 u，由阿拉伯糖、葡萄糖和糖醛酸组成，在260和280nm处有多糖无核酸和蛋白质的吸收峰。

Objective To Study of Air-disinfecting effects of eucalyptus disinfector for asepsis room.

Deciduous leaf is arboreal, can amount to 40 meters high, pectoral diameter can amount to 1 meter, plant is departmental without wool; Bark ecru or auburn, smooth; Long branch is long and thin, short branch is apart from shape, fold give birth to bulbiform bud scale fine and cicatricle.

落叶乔木，高可达40米，胸径可达1米，植株各部无毛；树皮淡褐色或赤褐色，光滑；长枝细长，短枝距状，具叠生球状的芽鳞良及叶痕。

Leaves 5 or 6 together; rachis, pedicel, and calyx tube glabrous.

一同的叶5或6；轴，花梗和萼筒无毛。

Ginsenoside R〓 was synthesised only in the root parts. Therefor, it is the characteristic component of ginseng root.

人参皂甙R〓仅能在地下部根中合成，茎叶均无合成能力，因此R〓是人参根的特征性成分。

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。
