An algorithm of multi direction projection pursuit is constructed to calculate multi directions of projection pursuit , the high dimensional data of hyperspectral remote sensing can be represented on a lower dimensional space more accurately 为此建立了多方向投影寻踪算法，以便求出多个投影寻踪方向，更精确地在低维空间中表现原始数据的空间分布规律。
But the irony of it is that as our world evolves , the more complex things and situations have become . it is no longer a matter of either or but somewhere in between . the grey area gives birth to flexibility , multiplicity , and fundamental changes 然而人类社会越进步，事物就越变得多样化，要定性在两极又谈何容易，灰色地带反而提供无限弹性，可作多方向的发展，甚至是带出本质的变化。
Aiming at the shortcomings of the routine inverse analysis methods which only utilize the data of single - survey - point and single - direction , a new method is brought forward in which the deformation observation data of multiple - point and multiple - direction are made use of the inverse analysis 针对利用单测点单方向位移资料进行反演的不足，提出用多测点多方向位移资料进行反演的方法。

2 reasonable inference and non - logical thinking should be attached great importance to in the course of thinking in multiple directions , students should be encouraged to think about problems in multiple directions or hypotheses as they can so that students " diverging thinking ability will be developed ( 2 )在多向思维中重视合情推理，非逻辑思维，应培养学生多方向的思考问题，尽可能的多找答案、结论或假设，培养学生的发散性思维。
During these years , gis ( geographical information system , or geo - information system ) is being on a rapid development phase not only in theory , but in application as well . it has become a research domain of multiple - subject crossing and multiple - direction discussing 近年来，地理信息系统( gis ， geographicalinformationsystem或geo - informationsystem )无论是在理论上还是应用上都处于一个飞速发展的阶段，并成为一个跨学科、多方向的研究领域。
When x direction seismic waves were input , the y direction dynamic displacements on the symmetry surface were nearly zero . but when three directions seismic waves were input , the y direction dynamic displacements on the symmetry surface increased rapidly to the same grade of x direction . so the three directions seismic waves were necessary for the dynamic analysis of the structures 输入x方向的地震波，在结构两个对称面上的节点沿y方向的动位移几乎为零，当输入三维地震波时， y方向的动位移则明显增大，达到与x方向同一量级，因此，对结构动力响应分析时，应输入多方向地震波，才能真正掌握结构的响应。
The methods of displaying slice about the three - dimensional emulation model are studied . they are follow three methods . the method to make multilayer horizontal slice ; the method to make multidirection and multiangle slice the method to make single oil layer display in three space . by above three methods the oil engineer can apprehend the underground oil reservoir structure very clearly 利用计算机图形图象处理技术，研究对地下油藏仿真模型的切片显示的方法，其中可完成多层水平片、可使人们在纵向空间对油藏有清晰的认识，完成多方向、多角度对油藏的垂直切片，使人们对油藏的整体构造有清晰的认识。
Structural internal forces and deformation caused by seismic load are bigger than that caused by automotive load . seismic load controls the designing of large span and small " width - to - span " ratio of large span cfst arch bridge . the seismic resistance is bigger than that with considering combination of various directions , so seismic load combination of various directions should been taken into account during design of large span cfst arch bridge 地震荷载所引起的内力和变形均大于车辆荷载引起的内力变形，对大跨、宽跨比小的钢管混凝土拱桥来说，应以地震荷载控制内力和变形设计，考虑多方向地震荷载的组合后，所得的地震力更大，说明在计算地震力时，应该考虑多方向地震荷载的组合。
This paper analyzed the data obtained at mcmurdo and thule neutron monitor ( nm ) stations and at guangzhou muon monitor station during the cme event in march 1991 . the results show that in this event when the cme structure passed the earth , it was shifted to the earth ' s southern hemisphere and the strongest magnetic structure associated with the cme passing the earth at about 2000ut , march 24 . 1991 我们利用mcmurdo和thule两个台站的银河宇宙线强度的观测数据和广州多方向介子探测器记录的宇宙线强度的数据分析了1991年3月cme的特征，注意到cme是一定程度地偏向地球的南半球，并给出了cme中最强的磁场结构到达磁层的时间为1991年3月24日2000ut左右，这是过去没有注意到的一个特征。
