肉眼观察

The gross observation, light microscopy, electron transmission microscopy, intravital microscopy and laser Doppler flowmetry were conducted on the combs at time of 5 rain, 10 min, 20 min and d 1 ,d 3 after irradiation.

分别于照光5min后即刻、照光10min后即刻、照光20min后即刻、照光20min后第1天、照光20min后第3天分别取6只鸡冠行肉眼、活体显微镜、激光多普勒血流图、光镜和电镜检查，观察鸡冠激光照射处皮肤微循环结构和血流状态的动态变化。

Methods: twenty rabbits with fracture of the femur diaphysis were treated by intramedullary nailing of femur with composites rod of resorbable dl polylactic acid calcium metaphosphate. the animals were sacrificed at 2, 4, 8 and 12 weeks after surgery. the fracture healing, the material degradation and mechanical properties were studied with x ray films, macroscopic, microscopic and electron microscopic observations.

用生物可吸收性聚乳酸/偏磷酸钙复合物棒对20只兔股骨髁上实验性骨折行髓内固定，术后2， 4， 8和12 wk分别经x线摄片、肉眼、光镜和电镜对骨折的愈合、材料的降解性能和力学性能进行观察。

Microorganisms are single-celled organisms that are generally microscopic, and smaller than the human eye can see.

微生物是单细胞生物体，体形十分微小，人类的肉眼根本观察不到。

As a result,the time course of the antibody titers to both I and II were parallel to that of macroscoopic and microscopic observations in an experimental mouse sporotrichosis model.

结果显示抗体滴度与实验小鼠孢子丝菌病肉眼和镜下观察的变化趋势相一致。

Detection method and that is:样纸 by strickle strickle color or simulate overprinting of method, on the standard sample and test specimens, observation of hue are consistent.

检测方法为：通过刮样纸刮色或者模拟印铁的方法，用肉眼对标准样和试样进行比较，观察色相是否一致。

DP is a non-invasive imaging technique for observing and characterizing epidermal and subepidermal tissue.

DP法是一种无创性观察体表和表皮下部肉眼无法识别的形态学特征与数字图像技术。

By the way, there's a second galaxy — M33, in the constellation Triangulum – that some experienced observers have glimpsed with the unaided eye, under perfect sky conditions.

顺便说一下，还有第二个星系- M33，位于三角座-是一些有经验的观察者在完美的天空状况下用肉眼捕捉到的。

Too small to be seen by the unaided eye but large enough to be studied under a microscope .

非用显微镜不可见的；微观的用肉眼不可见的但是可以用显微镜观察的

A Too small to be seen by the unaided eye but large enough to be studied under a microscope.

非用显微镜不可见的；微观的：用肉眼不可见的但是可以用显微镜观察的

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。
