不变化的

That is because the model is based on the ideal situation to presume the viewpoint as infinitely far away from the target. So it doesn't include the information of projection plane changing.

这是由于传统的模型是基于二维的平面运动模型，假设为投影点无穷远的情况，并不包含三维透视投影平面变化的信息，因此不能处理。

Soil erosion is the most serious ecological environmental problem in Loess Plateau of China. Unreasonable land use practice is identified as one of the most important reasons for triggering and aggravating soil erosion, and the driving mechanisms for land use change and the relationship between land use spatial pattern and soil erosion are the important aspects for the study about soil erosion.

And thus,the wavelet analysis has developed due to this demand, This thesis is to detect the point of signal discontinuity by wavelet transform.

小波分析正是由于这种需求而发展起来的通过小波变换来精确地检测信号发生变化的时刻，构造一个信号模型，由一个低频正弦波信号连接一个高频正弦波信号，利用小波工具可以检测出信号发生不连续的间断点的位置。

Then different runoff models and confluence processing patterns were adopted according to different characteristics of confluence inside and outside of polder s.

针对平原区下垫面多样变化和在分区内分布不均匀的特点，将平原区分解为水面、水田、旱地与城镇建设用地4种下垫面，分别采用不同的产流模型，根据圩区内外不同的汇流特性，分别采用不同的汇流处理模式。

It is shown that the porous structure of the copolymers changes as a result of the treatment with different solvents.

结果表明，在不同的状态中，高交联共聚物的孔结构是不相同的，它们的孔结构会发生变化。

But the constitution is less a prescriptive document than a constantly changing description of what has just happened.
