Triplets are seldom and monozygotic triplets are scarcely seen in humanity. There are few reports on triplets at home and abroad and diagnosis of zygosity is rarely made. We did the analysis of clinical material on two sets of triplets. Diagnosis and analysis of zygosity were made in eleven ways about 57 items including blood type and RBC enzyme type, etc.

鉴于光纤传感器具有体积小、结构简单、灵敏度高、抗电磁干扰且光纤本身的低损耗、耐腐蚀和安全可靠等优良特性,将光纤传感器应用到麦克风中可使麦克风的体积显著降低而灵敏度和抗电磁干扰性显著提高。提出一种新型反射式光纤麦克风的设计方法,采用Y形单根多模反射式光纤传感探头结构形式,给出了光纤麦克风的系统框图。由光纤出射光场分布理论出发,给出弹性膜片在声场作用下,中心形变大小h与出射光光强调制函数I(Z″)的关系。根据实际应用中有关参数的取值,用Matlab软件模拟出膜片形变后变形量h与光强调制函数I(Z″)的关系曲线。

The density functional theory at the B3LYP/6-311G（d, p） level was applied to exploring the inhibition mechanism of cholinesterases by carbamate. The results indicate that the inhibition reactions with or without the catalytic effect of the catalytic triad in eholinesterases underwent a two-step addition-elimination mechanism, which is in good agreement with the proposed mechanism. The solvent has a strong effect on the inhibition reactions and the reaction with the catalytic triad in the solvent phase is close to the real reaction under biological condition.
