A good landing is NOT flat, it should have a downward slope.
需要注意的是我们这里说的＂好的着陆处不是说着陆的雪道是平坦的，而应该是一个下坡。
The test bed used roller conveyor belt-driven precision seamless manner, the metering device stepless speed regulation, auto-injector scratch based on the kind of image processing and analysis of the tablets from the detection system can achieve precision seeder, and the planting of cereals Drilling Monomer, seed-sowing uniformity of the testing and other operating performance tests, with testing is accurate, reliable, intuitive and tablets from the source can be measured; using seed-column connection with the take-off and landing part of the body movements and Luo Shuan Metering device to achieve 11 ° tilt adjustment and height adjustment to simulate the movements slope planting performance test; PLC by a computer system with the implementing agencies in real-time control and achieve the performance of the whole-controlled trial.

The Kuytun city is located in the economical belt center of the north slope of Tianshan, along with the region social economy's fast development, the water demand sharp increase, the groundwater is over exploited seriously, flushes the lower part of the proluvial incline region in Kuytun River, the agricultural well irrigation area is coming into being the big groundwater landing funnel. The groundwater question is in reliefs day by day.
奎屯市位于天山北坡经济带中心，随着区域社会经济的快速发展，需水量剧增，地下水超采严重，在奎屯河冲洪积倾斜平原区下部的农业井灌区形成大的地下水降落漏斗，地下水问题日益凸现。
In consideration of the uncertain initial landing attitude angle of lunar lander and the unknown slope of lunar surface, a soft landing dynamic model is built.
考虑到着陆初始姿态角的不定和月面斜角的未知，建立起着陆器软着陆动力学模型。
Furthermore, when the initial landing attitude angle and lunar slope are very large, the attitude angle of lunar lander changes little, which ensures a smooth landing of the lunar lander.
而且当着陆初始姿态角以及月面斜角很大时，月球着陆器姿态角变化少，保证月球着陆器平稳着陆。
Increasing arresting force and improving low-speed aero characteristics can increase allowable maximal landing mass with an enlarged envelope area, but changing glide slope angle makes little effect.
通过增大拦阻力、改善飞机的低速气动特性可以有效扩展适配包线范围，增加许用的最大着舰质量，但下滑角大小的改变对其影响不大。
The influence of d/D, ratio and the location of piles on the safety factor for an example of a slippery slope of landing pier are discussed, and a design procedure of reinforcing piles is also proposed.
