These indexes describe the fabric's thermal properties during the heated process. The heat insulation ratio preferably manifests fabric's insulation property; the difference of calefactive ratio describes dynamic conditions average calefactive case; effective thermal conductivity and compound thermal resistance are mainly considering the wholly testing characteristics and describing the compound thermal property; the response time expresses the time of step response during dynamic testing process. 3. Dynamic heat transmitting properties of fabrics and warmth retention testing methods have been developed; many different textile materials are used for actual test, and the data are analyzed, illustrated, and compared.

450M, 1650m, 1850m and 2050m it is 54.04mm, 42.8mm, 56.38mm and 66.22mm respectively, showed in typical this world lay aside of moisture of slope upside soil is measured the biggest, of declivous seating arrangement, the region with moisture the poorest condition gives the slope in now.

结果表明：海拔1450m、1650m、1850m和2050m的0~50cm土层的年平均贮水量分别为54.04mm、42.8mm、56.38mm和66.22mm，表明了在典型阳坡上部土壤水分贮量最大，下坡位次之，水分条件最差的地带出现在中坡。

In this research, the pubertal five-week-old SD rats were chose as experimental object to establish the animal model for simulating maxillary protraction, on which was imposed the orthopedic force of 85g with utilizing the self-devised maxillary protraction appliance. Located lateral X-ray cephalograms were taken to measure and analyze the changes of maxillary development after exerting the orthopedic force for 4 weeks. The technique of immunohistochemistry was used to investigate theexpression of TGF-, in frontomaxillary sutures and palatomaxillary sutures with identical force performing for different extent of time. The average hue was selected as indicator, which was measured by the means of the analysis system of pathological color images. The measuring data were analyzed by the one-way ANOVA in software SPSS 11.0 version.

本研究采用自行设计的上颌前牵引装置，以生长发育期5周龄SD大鼠为实验对象，施加85g的矫形力，建立了模拟上颌前牵引的动物模型，通过X线头影测量分析，观察施力4周后上颌骨的生长发育情况；应用免疫组织化学技术，检测同一力值作用不同时段下TGF-β_1在上颌骨的额颌缝、腭颌缝的表达，彩色病理图象分析系统测定每张切片中阳性染色细胞的平均灰度值，结果采用SPSS 11.0进行方差分析。

In the intersatellite coherent optical communication, the vibration of a satellite will lead to a pointing error of transmitting and receiving antennas, which will decrease the signal-to-noise ratio and increase the bit error rate. In this paper, the Rayleigh distribution is taken as the pointing error model caused by satellite vibration, and PSK homodyne communication scheme is used as an example to analyze the influence of the satellite vibration on the system instantaneous BER and average BER. The simulation calculation result of BER is given.
