The equipment may be temperamental; the telescope mounting must be as rigid and controllable as for long-exposure astrophotography.

而且CCD经常变化无常，望远镜的支架必需足够坚固，并且对于长时间曝光要易于操控。

It isn't easy to be inspired in that spontaneous way for long periods at a stretch.

一连很长时间以这种即兴方式获得灵感是不容易的。

For solve problem these, we basis these design one computer lab fire prevention the burglary-resisting system, computer lab fire prevention burglary-resisting system through infrared sensor , temperature sensor , gas detector has lenses, spend the system lasting 24 hours to control to the computer lab to transmit to the picture , find unusual situation autoalarm , play a firing prevention theft- proofly role really , can make computer system relatively safe in one, in the reliable environment , operate steadily for a long time , and lengthen service life as much as possible .

为了解决这些问题，我们依据这些设计了一套机房防火防盗系统，机房防火防盗系统通过红外传感器，温度传感器，气体探测器还有摄像头，利用系统对图像传输对机房实施二十四小时监控，发现异常情况自动报警，真正起到防火防盗作用，能够使计算机系统在一个相对安全，可靠的环境里，长时间稳定地运转，并尽可能延长使用寿命。

They do not like to spend too much time discussing superficial or banal topics.

他们不喜欢花很长时间来谈论一些肤浅庸俗的话题。

Our results showed that only at higher concentrations or longer incubation timesdid BaP affect cell survival.

通过以上的研究发现，BaP只有在较高剂量和长时间处理情况下对细胞活力有影响；对细胞周期影响较明显，可使细胞滞留于S期。

People should look for a baseline that can work for a longer time.

人们应该寻找一种能够更长时间起作用的基准。

"Mandatory property management must be combined with good service in order to survive a long time."

"强制性物业管理必须结合良好的服务才能生存了很长时间。"

This will help you develop a realistic timetable for how long you can afford to be out of work.

这将帮助你产生可承受多长时间失业的一份现实时刻表。

There are major principles and secondary principles, and the latter should be subjected to the former.

我说有，多长时间在很大程度上取决于我们自己的内外政策和应对能力。

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。
