导磁不锈钢毛的结构化研究

研制了一种新型的结构化钢毛——胶结钢毛。和传统的普通钢毛相比,胶结钢毛具有很强的结构刚度和很低的钢毛流失量;同时,对高岭土有较高的除铁效率。     

低乙烯含量抗冲聚丙烯的结构表征

采用二甲苯为溶剂，将不同乙烯含量（５％￣１５％质量）的抗冲聚丙烯用特定程序进行分级，将各样品分为室温下可溶于甲苯和不可溶于甲苯的两部分。使用＾１３Ｃ－ＮＭＲ方法和ＦＴ－ＩＲ方法对各组分进行表征，明确了乙烯链段在聚丙烯链上的分布，并在此基础上提出了产生这种链结构的聚合工艺的特点。     

Impact of microstructure on stability of permanent magnet biasedmagnetoresistive heads

This work pertains to output voltage stability of soft adjacent layer biased magnetoresistive heads with abutted permanent magnetic films for domain stabilization. A micromagnetic model has been developed to study the effect of the permanent magnet film microstructure and the micromagnetic properties of the abutted junction interface on head stability. The impact on head stability is analyzed with respect to interfacial ferromagnetic coupling across the junction interface and intergranular exchange coupling in the permanent magnet films among other film properties

The role of human leukocyte antigen in susceptibility and clinical manifestations of sarcoidosis

To investigate the association of human leukocyte antigen (HLA) with susceptibility and clinical manifestations of sarcoidosis. Fifty-five patients with sarcoidosis were studied by using allele group specific polymerase chain reaction technique (PCR). Our data show that: (1) the gene frequency of HLA-DR5 is significantly increased in patients with sarcoidosis, but that of HLA-DR7 decreased. (2) Gene frequencies of HLA-DR9 and HLA-DR5 are relatively increased in male patients and in patients with stage I and stage IIa, respectively. The results suggest that HLA-DR gene might contribute to the susceptibility as well as to the difference of clinical manifestations in sarcoidosis.
