Torsional Pendulum

A computational model was developed to study the response of vestibular fluid to body motions, relating eye movement to vestibular displacement. The response in the semicircular canals (SCCs) and otolith organs were approximated as a torsional pendulum and a forced wave equation, respectively. The results of the math model were found to be consistent with results found in previous models. The results of the model will also be compared to those found experimentally using VALUS, a rotational platform updated to be used for vestibular testing.

Rotation Methods

Astronauts will suffer the orientation transformation problem without external force condition in spaceflight mission. Based on the establishment of human body system dynamics equation, the recommended control methods are put forward to guide the astronauts to make their orientation changed. The movement process is simulated through use of ADAMS to confirm the feasibility of method. Finally, simulated weightlessness environment is developed to demonstrate the advantages of the recommended control method compared with other control methods. The results show that using the control methods developed in this paper will make astronauts spend less time and smaller joint torques in performing body rotation about single axis in simulated weightlessness. There has certain reference significance for astronauts to conduct orientation transformation in spaceflight.

Synthetic Work

Hydroxyapatite bioceramics has attracted many material scientists as it is the main constituent of the bone and the teeth in human body. The synthesis of the bioceramics has been performed for years. Nowadays, the synthetic work is not only focused on the hydroapatite but also on the fluorapatite and chlorapatite bioceramics since later materials have also biological compatibility with human tissues; and they may also be very promising for clinic purpose. However, in comparison of the synthetic bioceramics with natural one on microstructure, a great differences were observed according to our previous results. We have investigated these differences further in this work since they are very important to appraise the synthetic bioceramics for their clinic application.The synthetic hydroxyapatite and chlorapatite were prepared according to A. Krajewski and A. Ravaglioli and their recent work. The briquettes from different hydroxyapatite or chlorapatite powders were fired in a laboratory furnace at the temperature of 900-1300°C. The samples of human enamel selected for the comparison with synthetic bioceramics were from Chinese adult teeth.

Important Basis

This is a combined study of two diffirent branches, photogrammetry and morphology of blood cells. The three dimensional quantitative analysis of erythrocytes using SEMP technique, electron computation technique and photogrammetry theory has made it possible to push the study of mophology of blood cells from LM, TEM, SEM to a higher stage, that of SEM P. A new path has been broken for deeply study of morphology of blood cells.In medical view, the abnormality of the quality and quantity of erythrocytes is one of the important changes of blood disease. It shows the abnormal blood—making function of the human body. Therefore, the study of the change of shape on erythrocytes is the indispensable and important basis of reference in the clinical diagnosis and research of blood disease.The erythrocytes of one normal person, three PNH Patients and one AA patient were used in this experiment. This research determines the following items: Height;Length of two axes (long and short), ratio; Crevice in depth and width of cell membrane; Circumference of erythrocytes; Isoline map of erythrocytes; Section map of erythrocytes.
