The performances of two steel tube enclosed precision thermistors are tested in a well controlled air environment to determine if the thermistors have enough accuracy for 0.01C levels of air temperature gradient measurement. Three Fluke's 5641 and three 5610 thermistors were tested for 24 hours in Fluke's 7008 calibration bath in the first step. In the second step
the performances of these two thermistors in steady state and transient state air temperature environments were tested for 8 hours separately. The results illustrate that
two of the 5641s were airproofed in a temperature well controlled tube
when steel tube enclosed precision thermistors are used in air temperature measurement
there are unstable departures from each other with a maximum 8.8 mC in constant air medium and 27 mC in temperature changing air medium. The transient-time errors are too large to show the true amounts of temperature changes for air temperature measurement. 2011 IEEE.

Based on the characteristics of off-axis aspherical surface
the comparison of simulation effects under different parameters is made. In order to achieve optimal parameters
a new method used for polishing off-axis aspherical mirrors-Double-Swing Method (DSM) is proposed in this paper
a high order off-axis rectangle aspherical mirror has been polished by DSM. The final result of profile measurements of 12nm
and the polishing mechanism of DSM is introduced. The mathematical model of the DSM with steady movement state is established.The movement of this mathematical model is simulated in a programming language
RMS is achieved. The result indicates that the method is of practice and has even higher working efficiency and precision. 2009 SPIE.
