objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

According to the current high real time peculiarity and high precision demands of beacon beam processing subsystem of space optical communication and the requirements of our project, the method that uses digital signal processor to solve the image position error signal extraction of beacon beam is proposed in this dissertation. It have the following advantages: the small system volume, the slight weight, the small power, the high real time peculiarity and the high precision and so on.

根据目前空间光通信对信标光处理子系统提出的高实时性和高精度性的要求以及课题的需要，本论文提出用数字信号处理芯片DSP来解决空间光通信中信标光的像面位置误差信号提取的问题，其优点就是系统体积小、重量轻、功耗低、实时性高、精度高等。

Features: high efficiency, small amplitude and high frequency of screening; it differs from the conventional screens with breaking of the surface tension of pulp and small granularity high speed vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore.

高频筛效率高、振幅小、筛分频率高。与普通筛分设备的原理不同，由于高频筛采用了高频率，一方面破坏了矿浆表面的张力和细粒物料在筛面上的高速振荡，加速了大密度有用矿物和析离作用，增加了小于分离粒度物料与筛孔接触的概率。

The results showed that the damaged starch contents of hard wheat were 20% higher than that of soft wheat under the same processing condition, and the damaged starch contents would be increased ...

研究结果表明：硬麦加工后淀粉破损率高，而软麦则相对较低，硬麦粉的淀粉破损率较软麦粉高出 2 0 %左右；面粉越细则淀粉破损率越高；研磨道数越多，研磨强度越大，淀粉破损越严重；齿辊所造成的淀粉破损程度要比光辊为重，但差距不是很大；撞击机在正常生产时对淀粉破损影响较小，如反复撞击也会使破损淀粉增加，但其影响程度较研磨强度缓和。
