In this work  micelles are formed by gradient copolymer of styrene and methyl methacrylate in acetone-water mixture and their temperature responsiveness is investigated in a narrow range near room temperature. Three different kinds of structural transitions could be induced by temperature: unimers to micelle transition  shrinkage/stretching of micelles  and morphological transition from spherical micelles to vesicles. In addition  a model analysis on the interface of gradient copolymer micelle is made to better understand these phenomena. It is found that both position and composition of the interface could alter in response to the change in temperature. According to the experiments and model analysis  it is proposed that temperature responsiveness might be an intrinsic and universal property of gradient copolymer micelles  which only originates from the gradient structure.

The position of focal plane will be changed because of temperature fluctuation and vacuum environment. In order to make the telescope work well  positioning accuracy of the mechanism is 0.008mm. The performance satisfies the need of precision  a focusing mechanism is needed. To majority of large space-based telescopes  and the scheme design is reasonable and practicable. 2012 IEEE.  the general way to do this would be to use a reflector  which was located in the backfocal distance. One of typical schemes of this mechanism was introduced  however  because of the big axial size  the mechanism can't be used when the size of the enclosure was limited. A new type of focusing mechanism was introduced  which has such advantages of small size  high accuracy and low mass. The design and test methods had been discussed. According to the results  the repeatability positioning accuracy is 0.0025mm

The thermal control indicators CAE methods of Space optical remote sensor are analyzed in the presented work. We sat up a thermal optical analysis model for space optical remote sensor. By assuming fully covered by in-orbit temperature load  and using the finite element method for thermal deformation analysis  we obtained the optical remote sensor surface deformation and displacement under various thermal loading. Using ZERNIKE polynomial  wave was fitted to obtain ZERNIKE polynomial coefficients which were incorporated into the optical system design. Using CODE V optical calculation software  heat-ray machines under elastic deformation of the system point spread function  transfer function (MTF)  wave front differential (WFE) etc. were calculated. Image quality changes of remote sensors are discussed in variety assumed cases such as temperature loads of quality change. By repeated iteration  critical value of temperature fields meeting the design requirements are obtained for the optical system. Optical indicators were converged to the temperature field indicator  then reasonable indicators of thermal control for remote sensors were obtained. For the thermal control design  this method provided a reliable basis for design. (2011) Trans Tech Publications  Switzerland.
