Substitute teacher is our primary school principals, he is a very old man's Bugouyanxiao that he had a double eagle eye, often on the natural course of my time on the very nature, I do not like this so I stifled the atmosphere, there is a very old man in particular Habits, with his glasses, I do not know if the old flowers or short-sighted glasses, not all the glasses on the bridge of the nose through the glasses with a man he did not, his eyes with a sharp nose, the man's time Head, above the framed glasses from the preview, this action has been very much afraid of me, the more quiet at a time when I knew that he would not issue a noise, and then the eagle eyes of my immediate aim, and then we all turned to see me ...... And for a long time ago, more and more like I do not like him, and he would seem to have any grudges against me more and more quickly verify my guess.

代课老师是我们的小学校长，他是一个很不苟言笑的老头子，他有一双鹰的眼睛，每每上自然课的时候我就很不自然，我不喜欢这个让我窒息的气氛，老头子有一个很特别的习惯，他带着的眼镜，不知道是老花还是近视的眼镜，不像大家把眼镜带着鼻梁上透过眼镜看人，他不，他把眼睛带着鼻子尖上，看人的时候低着头，从眼镜框子的上面瞄，这样的动作让我一直很惧怕，越在安静的时候我会发出不自知的噪音，然后鹰的眼睛马上就瞄准了我，然后大家都会扭头看我……久而之久，我好像越来越不喜欢他，他也好像也越来越跟我有仇，很快就验证了我的猜想。

By Laurie Barclay, MDJanuary 21, 2009 — Success in the primary care setting of either step-up or step-down treatment of new-onset dyspeptic symptoms is similar, but the step-up strategy is more cost effective at 6?months for initial treatment of patients with dyspepsia in primary care, according to the results of a double-blind, randomized controlled trial reported in the January 17 issue of The Lancet .

January 21， 2009 —根据一项刊登在1月17日Lancet的双盲、随机分派研究结果，在初级照护下，以进阶或是降阶治疗新发生消化不良症状的效果是相当的，但是进阶治疗策略对消化不良病患的起始治疗而言，在治疗6个月后更符合经济效益。

This paper describes the characteristics of the construction technique of floating plate ballast bed for subway at home and abroad and sums up the experience for the reference to the similar construction technique based on the construction technique of floating plate ballast bed with continuous-casting in place-metal elastic buffer in a double-tracked horseshoe-shaped tunnel of Shengzheng subway.

本文通过对深圳地铁一期工程单洞双线马蹄形隧道内，连续-现浇-金属弹簧隔振器式浮置板道床施工工艺的阐述，同时综合国内外地铁浮置板式道床施工工艺特点，总结了一些经验和认识，以供类似工程施工借鉴。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。
