We establish a microtechnique developed from cytochrome C spreading methods allowing the detection of minimal amounts of DNA through a calibrated composition of buffer、denaturing agents and cytochrome C in an extremely small volume of spreading mixture.

将变性剂脲、乙二醛、甲酰胺引入展开过程，我们在国内首次建立了可检测1×10〓--2×10〓ug以下量DNA样本的微量展层技术，能较好地展开dsDNA及ssDNA分子，DNA形态及长度与经典技术所制样本相似。

The high-efficiency compound flocculant-producing bacteria was acquired through separation and purification of flocculant-producing bacteria in soil, and they were authenticated systematically by using electronic microscope and DNA technology. The study shows that two are actinomycete and one is microzyme among three kinds of bacteria which have same characteristics of physiology and biochemistry.

安全、无毒、无二次污染的绿色水体净化剂———微生物絮凝剂，是环保界关注的焦点，但目前国内研制的微生物絮凝剂多由单一菌种产生，且基本上停留在小试阶段，并未取得突破性的进展，主要原因是产量较低和制取成本较高，同时也缺乏系统的鉴定(特别是从分子水平上给以说明)。

The two-dimensional effect is an important topic for the studies of the directed motion of molecular motors.

要更深入地研究分子马达的定向输运现象，考虑二维效应是一种可能的选择。

In the present paper, from the non-U(1) invariance of the atom-dimer conversion system, we generalize the definition of fidelity to this nonlinear system.

本文，从原子-二聚物分子转化系统的非U(1)对称性出发，将保真度的定义推广到了非线性系统。

Comparing with the structure of heme group that covalently linked to the polypeptide chain in natural heme proteins, we simulated the covalent modification of artificial Fe-salophen complex with amino acid histidine or dipeptide cysteinyl-histidine, with the intention of providing useful information for design of metalloproteins containing nonnatural prosthetic group.

通过比较天然血红素蛋白中血红素与多肽链进行共价连接的结构，我们对组氨酸或二肽半胱氨酰-组氨酸共价修饰人工配合物Fe-salophen进行了计算机模拟，旨在为设计包含非天然辅基的金属蛋白分子提供有用的信息。

The nonlinear least squares cost function was adopted and the numerator and denominator coefficients were estimated in a separated manner.
