探测器

On the basis of summarizing scientific goals of lunar exploration and analyzing distribution characteristics of landing sites, the authors chose three craters of Copernicus, Kepler, and Aristarchus in KREEP rock distribution area as candidate landing sites.

克里普岩对于研究月球的起源和演化有重要意义，但由于该岩石被玄武岩所覆盖，难以利用轨道探测器开展全面深入的研究。撞击坑是研究月表以下物质成分的窗口，在克里普岩区选择条件合适的撞击坑开展软着陆探测有助于对克里普岩的深入研究。

NASA says fresh images from the Phoenix Mars Lander show most of its science instruments are in good shape.

美国宇航局表示从凤凰号探测器发回的图片上显示，它的大部分的科学仪器运转都很正常。

Power for the lander had been getting short, and it was taking longer to recharge its batteries

探测器的能量变得短，它花长时间再充电它的电池

The two-dimensional physical model that chemical oxygen-iodine laser irradiates a disk target of InSb is established.

在激光对抗中，探测器容易受到激光损伤，为此研究了连续强激光对半导体材料的损伤机理，建立了氧碘化学激光器辐照InSb圆板型靶材的二维物理模型。

Methods The absorbed doses of patients in coronary artery angiography by INNOVA 2000 total digital flat-panel detector were compared with those by routine Advantx LCV.

方法应用INNOVA 2000全数字平板探测器心血管造影机，和常规机器比较冠脉造影患者吸收剂量。

It is being studied in the world how to reduce leakage current and to obtain the best detector.

如何把漏电流减少到最低限度，从而获得高质量的探测器，是目前国内外正在研究的重要课题。

We've put people on the moon, sent probes to Mars and Venus, lofted satelites near the sun (within a few tens of millions of miles), and one satellite even left the solar system a few years ago.

我们已经把人送上了月球，向火星和金星发射了探测器，把卫星发射到了太阳附近，甚至一个卫星已在几年前离开了太阳系。

To fly to the solar system space probes to other planets whose flight can be roughly divided into three stages, namely, from launch to the Earth's scope is not out of phase, out of the scope of the Earth's role in the transition phase, when mainly affected by solar gravity and scope to the target planet is the first three-phase, after which the planet could be captured by the target satellite, or left the target planet became the man-made asteroid.

飞往太阳系其他行星的空间探测器其飞行大致可分为三个阶段，即从发射到未脱离地球作用范围阶段，脱离地球作用范围的过渡阶段，这时主要受太阳引力作用，进入目标行星作用范围是第三阶段，此后可能成为被目标行星俘获的卫星，或者飞离目标行星后成为人造小行星。

In deep-space exploration, for some purpose, the probe is required to be at the libration points of the corresponding restrict three-body problem.

在深空探测中，出于某种探测目的，需将探测器定位在相应的限制性三体问题的秤动点上。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
