There are two categories to structure the robot model, One is describing the robot as a multilink model system which uses the detail parameters of the robot, such as the size, mass and CoM of each robot link, Its advantage is the model is much precise, but its computational hardness increase the difficulty to realize on-line planning.
Then we establish the general structure for slope walking.

Abstract.
The signal is rather strong, allowing the observation of the additional structures due to the hf interaction with two of the three nearest neighbour 29Si nuclei (I=1/2, 4.7% natural abundance) (HFa), as shown in Fig. 1.
The hf structure due to the interaction with two 29Si neighbours (HFa) is clearly seen (a slight splitting is due to a small misorientation caused by off-axis sample).

Valuable information about the chemistry of the phosphate synthetic oil after
high pressure using conventional and surface analytical techniques is available in the literature.
Internal structure and the distributions of some typical elements of the phosphate synthetic oil were analyzed with infrared spectroscopy.
It is seen that internal structure has no obvious changes besides one more peak.

Abstract.
Variations of surface structure and charge of sintered hydroxyapatite (HA) in simulated body fluid (SBF) were investigated during forming bonelike apatite on its surface using transmission electron microscopy accompanied with energy-dispersive X-ray spectrometry (TEM-EDX) and laser electrophoresis spectroscopy.
After some given periods, the surface composition and structure of the HA particles was analyzed using transmission electron microscopy (TEM: JEM-2000FXIII, Jeol Co., Tokyo, Japan) accompanied with energy-dispersive X-ray spectrometry (EDX: Voyager III, Noran Instruments, Inc., Middleton, USA).

In connection with this, specific phenomena associated with the size quantization of the energy spectrum of electrons can manifest in relatively large size structures [1, 2].
Model representations of electron tunneling through discrete levels of a quantum-size object in a structure typical for scanning tunneling microscopy (STM) measurements are shown in [3].

Efficient pretreatment was able to break the complex structure of lignocellulosic materials, separate or remove hemicellulose and lignin content from tightly interwoven cellulose content in the raw materials.
The reason of this phenomenon might be the inability of sulfite treatment to remove hemicellulose component, which counts for 25% in bagasse structure.
