长时间

Part Ⅱ human fibroblasts and keratinocytes were cultured on the Chitosan-BSA PEC scaffold for tissue engineered derma and epidermis.

用人的成纤维细胞和角质形成细胞在材料上做较长时间的培养，试图培养出完整的真皮与表皮。

I got to ask to go a-fishing; I got to ask to go in a-swimming -- dern'd if I hain't got to ask to do everything.

我已经很长时间没有到过别人家的地窖里，也许有许多年了。

There was no daybreak, and till long after the due hour, no light save a pale, sad glimmer at the window; now, at midday, I begin dimly to descry

没有黎明，直到在正常时刻的很长时间过后，没有光来挽救这窗户上的苍白、悲郁的迹象。

When you stare at a bright light for a long time, the photosensitive cells in your retina desensitize to the brightness and stop working as efficiently.

长时间注视发亮的光源会使视网膜上的感光细胞敏锐度减低，无法继续有效作用。

The only animal who can walk thtough the desert is the camel. He can go without food and water for a long time, and he can carry heavy loads. People call the camel "the ship of the desert".

唯一能穿越沙漠的动物是骆驼（thtough应该为through），它可以在没有食物和水的条件下坚持很长时间，而且能背得动沉重的行李，人们称骆驼为"沙漠之舟"。

Thermal oxidation treatment can increase the surface hardness and elastic modulus significantly and reduce the E /H ratio of the TC4, which indicate the treatment can enhance the wear resistance of TC4 alloy. Long time treatment can increase the thickness of the oxide layer, but the outside layer is apt to desquamate during the scratching. The oxide layer closing to substrate has better bonding properties, but microcrack forms as a result of high stress loading, which lead the layer to flake off completely.

长时间的高温氧化可以增加氧化层的厚度，但在划擦过程中氧化层发生两次脱落，表明氧化层由外表层和次外层组成，外层结合力差，易发生一次脆性剥落，内层与基体的结合强度较高，但在较大载荷作用下会产生微裂纹，导致氧化层的二次剥落。

If the temperature is allowed to get too hot for too long, the engine will self destruct.

如果温度长时间太热，发动机会自动破坏此温度。

He was determined to do it for a long time.

他决定做这件事已经很长时间了。

He works long hours to the detriment of his health.

例句1。他长时间的工作，有损健康。

He works long hours,to the detriment of his health.

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。
