The simulated results were preparatorily validated by using two-point nonuniformity correction method which was based on the linear response model of infrared focal plane arrays.

用以线性响应模型为基础的非均匀性两点校正法对仿真结果进行了初步验证，仿真结果表明：校正以后非均匀性明显下降，但仍剩余的非均匀性与红外焦平面阵列的理想化响应模型以及基于各探测元间是互相独立不相关假设下的非线性响应模型相比，基于空间相关性的红外焦平面阵列非线性响应模型更为科学、客观，也更接近真实的红外焦平面探测器成像。

Few scientists are willing to bestow credibility on theories which purport to explain how extraterrestrials could visit us, and the branch of investigation known as Ufology is branded as pseudoscientific nonsense.

几乎没有科学家愿意相信那些用以解释外星人如何造访地球的理论。研究不明飞行物的这一学说被称为荒谬的伪科学。

The records for the lives of the Pharaohs and Mahavishnu incarnate during the reign of Ancient Egypt are not complete yet; along with them were vast machinery used to psychically destroy the Mahavishnu that rebelled so very long ago.

不过，法老和 Mahavishnu 投生在古埃及统治年代的生命记录还并不完全。伴随其中的还有数目庞大的机械装置，那就是如此久远之前用以精神性摧毁 Mahavishnu 反叛者的事物。

Ideally, these factors should comprise three types of data: what the company does to attract and retain customers, the demographic and psychographic descriptors of the company's customer pool, and the actual buying behavior of those potential customers (how much they buy, how often, what share of wallet, and so on).

这些因子应该由三种类型的数据组成，即：公司用以吸引和留住客户的措施，公司客户资源库的人员统计和心理变数的描述符，这些潜在客户的现实购买行为（他们的购买量、购买频次、购买所花费的钱占整个收入的比例，等等）。

Risk and maneuverability analysis on engineering design is widely used to conduct security appraisal abroad. The potential risks might be caused by technical parameter deviation, failure and faulty operation of facilities and pipelines in the system were normally analyzed along with the reason why deviation and faulty operation occurred. The acceptable risk was then appraised according to the results, reasons and designed protective facilities. Later, the security countermeasures and solutions were brought forward purposively to further modify and refurbish the security design and operation management.

国外广泛应用危险与可操作性分析对工程设计进行安全评价，分析系统中装置、设备、管道的个别部分工艺参数偏离、故障或误操作引起的潜在危险，分析偏离、故障出现的原因，根据后果、原因和已设计的保护装置，评估可接受的风险，并有针对性地提出安全对策和措施，用以指导修改、完善工程的安全设计和操作管理。

If you are unable to control the bleeding in any other way,+ and professional help is many hours away, apply a tourni-+ quet to the affected extremity.

如果无法用以上的几种方式止血，并且可能在几小时后才能得到专业的帮助，那么可以用止血带包扎出血的肢体。

Rajiv Gandhi famously remarked that only 15% of government money intended for India's poor ever reached them.

拉杰夫·甘地曾说过一句著名的话：原本用以发放给印度穷人的政府款项中，只有15%最终能到达他们手中。

In the design of the road test, a reflectional infrared sensors is used to detect the black line on the road to judge the trolley's position; on trolley's speed controlling, the control system uses PWM technology to control the rotational speed of electric motors, and complete the speed real-time control to electric cars in d

在路面检测设计中，小车采用反射式红外传感器来检测其行驶路面上的黑线，以判断小车行驶的位置；在控制小车行驶速度上，系统利用PWM技术控制电动机的转速，通过程序完成对电动小汽车在不同路段的行驶速度实时控制；最后采用双电源供电，用以保证系统的运行更加稳定，可靠。

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。
