Usingthis method, the GSH content of Rana nigromaculata tadpoles under different concentrationsof Na2SeO4 and Na2SeO3 were measured. The induce of selenate to the content of GSH intadpoles makes its variation has well time-effect and dose-effect relationship. Thesephenomena demonstrate that GSH is smart to the exposure of selenate, and therefore can beused as a sensitive index to selenate pollution.

①将126例急性创伤性血胸患者分为小量、中量、大量3组，测定患者入院当时、24 h、及72 h的血浆凝血酶原时间、活化部分凝血活酶时间、纤维蛋白原、血小板值，并与43例健康对照组比较。

Fluorescence spectra were measured at consecutive time points in an emission range of 439～550 nm for every sample when a constant 390 nm excitation wavelength was used, hence, creating a three-way response data array which was then analyzed by trilinear decomposition method.

设定激发波长为390 nm，在发射波长为439～550 nm的范围内测定一段时间内连续时间点的该动力学反应中间物的荧光光谱，构建三维响应数据阵，然后运用三线性分解算法进行解析。

In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

ABSTRACT］ Objective To study the pharmacological effects of oral medical ice and to provide for its evidence for clinical application. Methods The anti-inflammatory effect of OMI was determined on three inflammatory models: swelling of mice ear induced by dimethylbenzene, hind paw edema and back granuloma caused by hypodermic injection of agar in rats. The an- algesic action of OMI was studied by observing the mice's reaction to the heat simulation. The effect of OMI on bleeding time was tested by tail-cutting method.
