自制和进口试剂盒在犬细小病毒检测中的应用

用本研究室研制的犬细小病毒单克隆抗体和多克隆抗体，采用夹心ＥＬＩＳＡ原理，研制成功犬细小病毒快速诊断试剂盒。对８７份犬粪便样品进行检测，并与ＨＡ法和美国ＩＤＥＸＸ公司研制的ＥＬＩＳＡ试剂盒进行比较。结果表明，与ＨＡ法相比，自制试剂盒的敏感性为９３．３％，特异性为１００％，总符合率为９５．４％；与美国试剂盒相比，自制试剂盒的敏感性为１００％，特异性为８４．６％，总符合率为９５．０％，达到国外同类产品     

拟似然非线性模型中最大拟似然估计的强相合性

This paper proposes some regularity conditions. On the basis of the proposed regularity conditions, we show the strong consistency of maximum quasi-likelihood estimation （MQLE） in quasi-likelihood nonlinear models （QLNM）. Our results may be regarded as a further generalization of the relevant results in Ref. [4].     

负二项分布类的条件概率封闭性

在研究只允许部分服务台进入休假状态的多服务台M／M／c排队系统时，我们发现了条件Erlang分布的一些有趣的性质，进一步研究我们发现相对应离散随机状态的负二项分布也具有很好的性质（概率封闭性．本文证明了一类负二项分布的概率封闭性．它们对导出复杂排队系统中离散状态下顾客等待时问分布及保险公司中破产概率上界的计算起着重要作用．     

金属薄膜短脉冲激光冲击热机耦合问题

从电子-声子相互作用的双曲型两步热传导模型出发,考虑到金属体内晶格对热传导的影响,采用有限元法,直接在时间域中求解了金属薄膜内受短脉冲激光加热的二维热机耦合问题,避免了以往因电子-声子能量方程之间的耦合关系给二维热响应问题解析求解带来的困难,提高了用数值反变换工作时计算的精度,减少了工作量,得到了金属薄膜内二维热机耦合问题的温度、位移和应力的变化规律.     

Ferric chloride-catalyzed decarboxylative alkylation of β-keto acids with benzylic alcohols

β-Keto acids are unstable to heat,acids,and bases,and have rarely been employed as carbon nucleophiles for the formation of carbon-carbon bonds.In this context,an efficient decarboxylative alkylation reaction of β-keto acids with benzylic alcohols has been developed,for the first time,through sequential cleavage of carbon-oxygen and carbon-carbon bonds.In the presence of 10 mol% of ferric chloride,a range of β-keto acids smoothly undergo decarboxylative alkylation with benzylic alcohols to give structurally diverse unsymmetric ketones in moderate to excellent yields and with extremely high regioselectivity.Preliminary mechanistic studies indicate that the reaction proceeds through an SN1 alkylation followed by decarboxylation.     

Orthorhombic B2CN crystal synthesized by high pressure and temperature

B_0.54C_0.28N_0.18 precursor powder with turbostratic structure was prepared by using melamine and boric acid. The precursor was transformed into orthorhombic B₂CN under definite high pressure and temperature conditions. The composition of the orthorhombic B₂CN powder is B_0.47C_0.23N_0.30. Its lattice parameters are a=0.4776 nm, b=0.4585 nm and c=0.3629 nm. A strong absorption band from 1088 to 1385 cm⁻¹ of orthorhombic B₂CN was observed by infrared measurement. In the photoluminescence (PL) spectrum of orthorhombic B₂CN powder measured at room temperature, a broad peak corresponding to its band-edge emission centers at 374 nm.     

中国蜜环菌生物种E与其它种的相互关系

中国蜜环菌生物种Ｅ（ＣＢＳ Ｅ）建立时仅包括２个菌株，尚未建立起完整的交配型交配菌株体系，与其它中国蜜环菌生物种的相互关系也不清晰。依据交配试验结果，将原ＣＢＳ Ｅ中的９２０１８归属ＣＢＳ Ｃ，将９２０１１归属于ＣＢＳ Ｄ，即把ＣＢＳ Ｅ合并为奥氏蜜环菌ＣＢＳ Ｄ，Ａｒｍｉｌｌａｒｉａ ｏｓｔｏｙａｅ（Ｒｏｍａｇｎ．）Ｈｅｒｉｎｋ。
