查询词典 be observed

Venus is the easiest planet to identify since it is, after the Sun and the Moon, the brightest object in the sky; it is a brilliant yellow-white in color and can be observed even in daylight.

其颜色呈鲜明的黄白色，即便是在白天也能看到。从地球上观察时，我们发现，金星像月球一样有一个新月期：距地球最远时，它看起米非常小；当它靠近地球时，它就会变大。

It should be observed that faults on the line terminals of breakers A and C can collapse the generator voltage.

应当指出，断路器A或C上的接线端子上的故障甚至能损坏发电机电压。

The results show that glass ceramics with thermal expansion coefficient of 5.11×106 ℃, major phase of α-cordierite and εr=5.5, tan σ=2.1×104 can be prepared by the addition of 3.6% alkalis(Li2O+Na2O), and Li2O occupies 1.8%. With Li2O substitution for Na2O, spontaneous crystallization is obviously enhanced, and temperature of the first crystallization peak decreases from 950 ℃ to nearly 900 ℃, but the crystallization temperature of the second peak was not varied. With the increase of Li2O content, mixed alkali effect can be observed from the thermal expansion coefficient and dielectric loss curve which decreases first and then increases. Dielectric constant decreases monotonously with the increase of Li2O content.

研究结果表明：Li2O和Na2O总含量为3.6%，其中Li2O含量为1.8%时，微晶玻璃以α-堇青石为主晶相，热膨胀系数为5.11×106 ℃，微波频率下介电常数ε r为5.5，介电损耗tan σ为2.1×104；随着Li+对Na+的取代，玻璃的析晶能力增强，初始析晶峰温度从950 ℃降至900 ℃左右，但没有降低第二析晶峰温度；随着Li2O含量增加，热膨胀系数及介电损耗都出现明显的混合碱效应，曲线呈现先降低后升高的变化趋势；样品的介电常数随Li2O含量增加单调降低。

Some of transplanted cells expressed titin and the assembled titin could be detected in the cells adjacent to host myocardium. Cx43 could be observed between these cells. But the size and structure of transplanted cells were different from normal contractile myocardium.3. Most of the grafted cells were isolated by fibrous tissue. Part of these cells differentiated into fibrocytes. The structure of host myocardium was slightly disturbed.

MSCs植入正常心肌组织后能存活至12周，部分移植细胞表达titin，且与宿主心肌细胞相邻的细胞表达titin组装程度更高，随时间延长表达逐渐明显，其后进入平台期，但细胞体积及胞浆发育均不及正常心肌细胞；在移植细胞与宿主细胞之间可检测到Cx43的表达。

RESULTS:①Amputated arm of Chinese fire-bellied newt could be fully regenerated in ten weeks, during which process great amounts of skin fibroblasts could be observed in the limb buds.

结果： ①东方蝾螈断肢后10周左右肢体成功再生。肢体再生过程中，肢芽中出现大量皮肤成纤维细胞。

Pairs of telescopic fields must be observed, alternating about every half hour, so that the positions of radiants can be defined.

对伸缩领域必须得到遵守，交替约每半小时，使的立场radiants可以被界定。

Through the analysis of De, an alternative mechanism interpreting of the"overshoot"phenomena can be obtained: when the diffusing time of small molecular penetrants is shorter than relaxation time of the involved polymer, small molecular substance penetrates into the polymer quickly and its concentration reached a maximum, then the swelling of the polymer by the small molecules makes the chain structure of the polymer relaxed, thus the free volume in polymer matrix, which is occupied by small molecule, decreased, and will squeeze part of the small molecular substance out of the polymer, and therefore overshoot behavior can be observed.

通过对De的分析，可以得出产生&超调&现象的机理的另一种解释：小分子渗透物质的扩散时间相对于聚合物的松弛时间要短（相当于有个更快的扩散速度），所以小分子迅速扩散进聚合物中达到一个极值，由于小分子物质对聚合物的溶胀，使得聚合物链结构产生松弛，由于聚合物链结构的变化，小分子物质占有的自由体积会减小，这样会挤出小分子物质，使得小分子物质在聚合物中的浓度减小，如果高聚物粘弹性明显，甚至可能出现多个浓度的衰减振荡并达到平衡值。

Each wavelength of optical radiation has an associated threshold retinal exposure level that must be exceeded in order for retinal damage to be observed - shorter wavelengths are more effective in that less energy is needed.

对应每种波长的光都有一个极限值，超过这个极限值才能使视网膜受到损害。对於较短波长的光幅射，这个极限值的能量强度较低。

With involvement of the L4 root, the patellar tendon reflex may be diminished and slight quadriceps weakness may be observed.

受累侧跟腱反射消失，病人不能反复用足尖踮立，感觉症状包括小腿后外侧和足有疼痛及麻木感。

In order to duplicate these performance tests, the following precautions should be observed:-The mixer should be presented with good return losses at all ports by using isolators or attenuators.

为了重复这些性能测试中，应遵守以下预防措施：-的搅拌机应在隔离器或衰减器使用的所有端口的损失提出良好的回报。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
