The lifetime of M intermediate of the three mutants in PVA films were recorded by employing photomicrography. In distilled water, the visible absorption maximum of BRI119T/T121S/A126T and BRI119T/T121S/A126T/E194Q mutants were blue shifted notably by 11 and 12 nm respectively and the BRE194Q's was weakly red shifted in comparison with WT-BR.

与野生型BR相比较，在水溶液中，单突变体的可见吸收光谱的最大吸收峰发生了轻微红移，三突变体和四突变体的最大吸收峰则分别发生了11.0和12.0 nm的明显蓝移。

It indicates that the different parts of the cattle-egg stone samples in different colours all mainly compose of pyrophyllite, coexisted by two kinds of polytype of monoclinic and triclinic pyrophyllite, and the average crystal structural formula is Al4.04 Si7.89 Al0.11O204. The aggregation of pyrophyllite arranges with no direction, and the crystal size of the single pyrophyllite crystal in the weathering skin is a little bigger than that in the basal part.

结果表明，不同颜色牛蛋石样品的不同部位皆以叶腊石为主要成分，并以叶腊石的单斜和三斜两种多型共存，其平均晶体结构化学式为Al4.04[Si7.89Al0.11O20]4；其叶腊石集合体呈无定向排列，风化皮中叶腊石单晶的粒度略大于基体中的。

Methods We enrolled 551 vitiligo patients with psychological problems from total 7443 patients with vitiligo after investigating sexuality, profession, area of lesions, distribution, reactiveness and typing by filling out the epidemiological questionnaire, and then we analyzed the correlation of psychological problems and clinical manifestations. Statistical analyses were performed using SPSS-13.0 software, and the data were analyzed by Chi-square test and variance analysis.

采用统一制定的流行病学调查表，调查员对白癜风患者进行面对面同等细致询问，就其性别、职业、皮损面积、单双侧分布、皮损的活动性及分型等情况进行调查，并让患者自身评价其心理状况，从7 443例患者中筛选出551例自觉有心理问题的患者，分析上述临床资料与心理问题的相关性。

Firstly, based on the force acting on a single-particle, establish a discriminant formula of the sand threshold, and prove that the sand threshold belongs to the cusp catastrophe. Then establish the basic equation of the cusp catastrophe using coordinate transformation and catastrophe theory. Finally, while particle Reynold number and equivalend diameter are the state variables and Shields parameter is the control variables, we can obtain the model of cusp catastrophe of sand threshold, putting those variables into the basic equations of the cusp catastrophe. The model is derived from the mathematics, which has a certain mathematical theory foundation.

首先从单颗沙粒受力分析出发，建立沙床沙粒起动条件判别公式，进而证明了风沙起动属于尖点型突变；然后通过坐标变换和突变理论建立了尖点突变的基本方程；最后本文选择颗粒雷诺数和等效粒径作为控制变量，希尔兹参数作为状态变量，并把它们代入尖点突变的基本方程，经过拓扑变换得到风沙起动的尖点突变模型，并与前人的公式及实验数据进行比较。

The relationship between a typical sigmoidal curve of denaturation and the process described by twostate model is analyzed in detail. It is shown that sigmoidal behavior does not mean that the unfolding process of the single-domain protein is two-state behavior.

通过对典型的S形变性曲线与二态模型之间的关系所作的详细分析，进一步强调变性过程表现为S型曲线，并非说明单结构域蛋白质的变性过程一定是二态过程。

Specific gene expression of the pro-inflammatory cytokine IL-1β and the type II IL-1βreceptor (IL-1RII, 'decoy receptor') was studied in skin of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) fry during infection with the ectoparasitic monogenean Gyrodactylus derjaini Mikailo, 1975. Cytokine expression was studied in both primary and secondary infections using a semi-quantitatie RT–PCR technique.
