The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

Five novel torsion-mirror optical actuators including double-beam thickness differential structure with single torsional axis, double flexible folded-beam structure with single torsional axis, double-beam vertical torsion comb structure with single torsion axis, four-beam differential compound-micromirror structure with double torsional axis and the combined structure of the four basis forms above, are brought forward. All of these devices could be fabricated by the same silicon micromachining process we have developed. The deformation compensation design with local enhancement for the thin torsional beam which is the key structure of these devices is also put forward to improve the reliability. The three-dimension solid model and two-dimension reduced order model of the torsion-mirror optical actuator are established and then the numerical simulations for evaluating the device characteristics of the statics, dynamics, electrostatic field, mechanical and electrostatic coupling, fluid and solid coupling are carried out to optimize the structure design. Furthermore, three optical fibre clamping structures which could be integrated monolithicly are designed and analyzed to improve the optical coupling capability. 4. Three flexible process flows combined with bulk silicon micromachining and surface silicon micromachining are brought forward to fabricate these novel single-crystal silicon or polysilicon torsion-mirror optical actuators by using the same lithography masks for both SOI wafer and regular silicon wafer. A series of important process experiments are carried out to optimize the process parameters and the process flows. Some novel and typical process phenomena which occurred during the microfabrication are analyzed and then the corresponding solutions are put forward. 5.

The results revealed that nine of the fourteen Y-specific markers cannot be used for investigating the swamp buffalo Y chromosome genetic diversity because of the reasons specified below: three microsatellites markers (INRA008, UMN0103 and UMN0504) were single allele and monomorphism, three (UMN1113, UMN0304 and BC1.2) indicated three alleles respectively but mornomorphism, and the other three (UMN0920, UMN0307 and UMN3008) showed irregular ladder-like bands. Only the remaining five microsatellites (INRA124, INRA189, BM861, PBR1F1 and UMN2001) indicated polymorphisms, and thus can be applied to study the swamp buffalo Y chromosome genetic diversity.

结果表明，3个标记（INRA008，UMN0103和UMN0504）只有1个等位基因，表现为单态；3个标记（UMN1113，UMN0304和BC1.2）均为3个等位基因，但呈单态；3个标记（UMN0920，UMN0307和UMN3008）呈现无规律的梯状条带，所以这9个标记都不适用于水牛的Y染色体遗传多样性研究；只有5个标记（INRA124，INRA189，BM861，PBR1F1和UMN2001）具有多态性，表明适用于水牛的Y染色体遗传多样性研究。
