Examples
- For the power descent mission , two guidance methods are presented based on polynomial planning and sequential quadratic programming
针对动力下降段任务,给出了基于多项式规划和二次序列规划的月球软着陆制导方法。 - In this paper , image based autonomous navigation algorithms are studied deeply for the asteroid landing phase
本论文针对小行星探测器下降段的特点,对基于图像序列的小行星软着陆自主导航方法进行了系统深入的研究。 - For the convenience of calculation , ascending branch was simplified into a direct ratio formula and descending branch was simplified into two straight lines divided by knee point
从方便计算的角度上建议上升段采用比例方程表示，下降段简化为以拐点分界的两部分直线。 - The descending part of the curves are much sharper than the ones under the normal temperature . the ductility of the concrete will also get worse and the brittleness will increase
应力?应变曲线形状随负温值的增大变得高而窄，曲线的下降段比常温陡直，混凝土的延性变差，脆性增大。 - The whole tension strength of steel fiber reinforced self - stressing concrete is a combination of tension strength of matrix and the self - stress value ; the strain of knee point is defined to 500 10 ^ ( - 6 ) , and a formula for stress of knee point is suggested
钢纤维自应力混凝土抗拉强度为混凝土基体的抗拉强度与自应力值之和；曲线下降段拐点的应变定义为500 10 ^ ( - 6 ) ，并提出拐点应力计算公式。
