比较星

Introducing the user algorithm of the broadcast ephemeris, the algorithms are explained on principle, which are Lagrange Interplation and Chebyshev polynomial simulation. Then comparisons of calculating of satellite coordinate with broadcast ephemeris and with precise ephemeris are made.

推导了广播星历用户算法，对GPS数据处理中常用的拉格朗日内插和切比雪夫多项式拟合从原理上进行了阐述，并对广播星历卫星坐标计算和精密星历卫星坐标计算进行了分析比较。

The result shows: at different temperatures the outcomings obtained in determining dissociation constants with such two theories can be seen effective, but the doubly reciprocal curves of quenching equation are not conformed to quenching curves based on dynamic and static quenching mechanism as those of fluorescence enhancement.

通过荧光和紫外方法研究盐酸左氧氟沙星、氟罗沙星、加替沙星和沃氟沙星四种喹诺酮类药物与人血清白蛋白的作用，在不同温度下对荧光加强和猝灭理论公式的等价性和精细差异进行了比较，结果表明：在不同温度下两种理论公式尽管在求取解离常数上所得结果都可视为有效，但猝灭方程的双倒数图反而不及荧光加强方程的双倒数图与体现动态、静态猝灭机理的猝灭曲线一致。

But that's not a totally fair comparison, because Spica is not just one star, but a spectroscopic binary.

但那并不是非常公正的比较，因为天门星不只是一颗星，而是可用分光镜看见的双体星。

This paper compares the position and clock offset of the satellites insight obtained from the broadcast ephemerides file five days prior and posterior to the cancel of SA policy on WUHN station with that provided by final IGS precise ephemerides.

利用全球GPS永久性跟踪站WUHN站在SA取消前后五天的广播星历文件计算得到在视卫星的位置和钟差，与事后IGS精密星历提供的卫星位置和钟差进行比较分析，说明SA取消对广播星历的影响。

The elimination half-life t(subscript β1/2 was 161.10h, 333.21 h and 611.26h, respectively, and the total body clearance was 27.4mL/, 16.8g/ and 18.0g/, respectively. The metabolite ciprofloxacin concentration-time profiles of the plasma, muscle and liver presented similar trend. The multi- peak phenomenon were observed in the plasma, muscle and liver, but the first peak time was 24h, 24h and 12h, respectively. The peak residue of metabolite ciprofloxacin was in liver, muscle and plasma, ordinally. The eliminating rate of ciprofloxacin from muscle and liver was very low.

代谢物环丙沙星在鳗鲡血浆、肌肉和肝脏中药物水平的变化趋势与恩诺沙星基本相似，呈现出多峰现象，但3种组织中环丙沙星出现第一个药峰时间分别为给药后第24小时、24小时和12小时，3种组织中环丙沙星峰值水平肝脏中最高、肌肉中次之、血浆中最低，环丙沙星在肌肉和肝脏中的消除速率比较缓慢。

The changes of muscle protein content and pH values were observed. Results Thymus and spleen coefficients in high and low dosage group were 9.1±2.3, 6.3±1.1, respectively, and those of in the controll were 6.5±1.6, 3.4±0.5.The contents of muscle protein (g/100 g) in high, medium, and low dose groups were 24.68±0.55, 22.48±0.54, 21.22±1.25, respectively, lower than that of the control (31.83±2.36, P.05). Paramorphia of lymphocyte in high dose ciprofloxacin treated group was observed.

结果 对照组胸腺和脾脏系数分别为(9.1±2.3)，(6.3±1.1)mg/g，高剂量组胸腺和脾脏系数分别为(6.5±1.6)，(3.4±0.5)mg/g，与对照组比较，差异均有统计学意义（P.05或P.01）；而中、低剂量组的脾脏指数与对照组比较，差异均有统计学意义(P.05)；环丙沙星各剂量组与对照组比较，肌肉pH值变化不明显；环丙沙星高、中、低剂量肌肉蛋白质含量分别为(24.68±0.55)，(22.48±0.54)，(21.22±1.25)g/100 g，与对照组(31.83±2.36)g/100 g比较明显下降(P.05)；与对照组比较，高剂量组脾淋巴细胞形态异常。

Where should I obtain my comparison star coordinates?

我该从哪里获得匹配的比较星坐标？

Using these x,y measurements (determined to a fraction of a pixel) and the comparison star coordinates (taken from a suitable reference catalogue ), the program should then do a least-squares plate-constants solution to derive the unknown coordinates of the minor bodies.

利用这些像素坐标以及比较星的坐标（从一些合适的比较星星表获得），软件将进行一个LSPC操作来计算小行星的坐标，很多软件做不到这一点。

When using a star catalogue that is complete down to a certain limiting magnitude (i.e., the USNO-A2.0 or the UCAC ), a small number of stars (10 to 30) is usually sufficient.

当使用的星表是那种完全限定在某极限星等之下的数据的（比如：USNO-A2.0或UCAC星表），一个比较小的匹配星数目就一般足够了。

METHODS: An open, randomized, twoperiod crossover study was conducted in 18 healthy volunteers. Concentrations of gatifloxacin in plasma were assayed by HPLC after a single oral dose of 400 mg of the tested capsules or the referenced tablets. The main pharmacokinetic parameters ［AUC（0-24h）, Cmax and Tmax］ were analyzed by two onesided t test. RESULTS: The concentrationtime curve after medication conformed to onecompartment open model with a first order absorption.

采用双周期随机交叉、自身对照试验设计法，将18例男性健康志愿者随机分为两组，分别单剂量口服甲磺酸加替沙星胶囊400 mg和甲磺酸加替沙星片400 mg，经1 w清洗期后交叉换药，以高效液相色谱法测定受试者服药后血浆中加替沙星的经时浓度，计算加替沙星药动学参数，以双单侧t检验统计法比较两种甲磺酸加替沙星制剂是否具有生物等效性。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
