InSAR是一种极具潜力的新型空间大地测量方法，但它也有其固有的限制，特别是受到大气层延迟（对流层延迟、电离层延迟等）、卫星轨道误差、地表状况和时变去相关性等影响，很容易导致InSAR图像解释错误，而InSAR数据本身无法解决所存在的上述问题。而GPS可以精密定位，可以较为精确地确定电离层、对流层参数，是当前应用最广泛的一种空间大地测量手段。-InSAR is a potential new space geodetic methods, but it also has its inherent limitations. in particular by the delay in the atmosphere (troposphere delay, ionospheric delay, etc.), satellite orbit errors, Surface conditions and time-varying correlation to the impact of such very easily lead to wrong interpretation of InSAR image, InSAR data and by itself can not solve the above problems. GPS precision positioning can be more accurately determine the ionosphere, troposphere parameters, is the most widely used as a means of space geodesy.

加强肋
理想的设计
为了克服壁厚大可能引起的问题，使用是一种可减少壁厚并能增加刚性的有效方法。
一般来说，部件的刚性可用以下方法增强
增加壁厚；
增大弹性模量（如加大增强纤维的含量）；
设计中考虑。
如果设计用的材料不能满足所需刚性，则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是，在特定壁厚下，这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大，部件的刚性便会增大。在优化的尺寸时，不但要考虑工程设计应当考虑的问题，还应考虑与生产和外观有关的技术问题。
优化的尺寸
大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料，这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且，如果的高度过高，在负荷下结构将有可能膨胀。出于这种考虑，必须在合理比例内保持的尺寸（见图1）。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in s
