a large paved double courtyard which was level, despite the steep gradient of the hill.

Gravity gradient is the second order derivative of gravitational potential, which can be observed by satellite gradiometer.

Klinotaxis refers to movement through a gradient while taking successive samples of the environment.

Conclusion ADC and signal intensity in lentiform nucleus were not affected by diffusion gradient directions.

A gradient of 1 in 4 is a rise of fall of one metre for every four metres forward.

This point out that in order to improve the LMS algorithm performance, the gradient are optimally estimated, or the error signal are nonlinearity processed,these methods are equipollent.

The influence of different diffuse gradient direction in different lesions of human brain on diffusion-weighted image has become one of the focus researches of neuroradiology.

Image reconstruction is often converted to the nonrestraint extremum of the nonlinear equations.We have deduced a conjugate gradient algorithm from the extremum of norm.

This study describes the application of the feedback linearization neural networks, known from neural network computing, to the problem of gradient preemphasis.

Methods:We separated the subfractions of LDL by precipitating method and density gradient ultracentrifugation, and identified the subfraction by electronphoresis and electron microscope.
