The "unsampled pig herd" theory was suggested by Smith and his colleagues who concluded that "the progenitor of the S-OIV epidemic originated in pigs" and the "long unsampled history observed for every segment" of the S-OIV genome "suggests that the reassortment of Eurasian and North American swine lineages may not have occurred recently and it is possible that this single reassortant lineage has been cryptically circulating rather than two distinct lineages of swine flu" and that "Movement of live pigs between Eurasia and North America seems to have facilitated the mixing of diverse swine influenzas leading to the multiple reassortment events associated with the genesis of the S-OIV strain."

After verification of the program, the mathematical models of the suspension bridges were studied by means of the program, as well as the determination of the main cable's shapes and its internal forces at different stages, the calculation of the cable's unstrained length and the analysis of the construction processes, of which some new approaches were presented in the mean time. Thus makes the structural analysis results of suspension bridges more reliable and in accordance with reality.

在用算例验证了程序分析结果正确性的基础上，应用该程序对悬索桥的数学模型、各阶段缆索几何形状及内力状态的确定以及缆索无应力长度的计算和施工过程分析进行了研究，提出了确定缆索在成桥状态下的几何形状及其内力状态以及缆索无应力长度计算的新方法，使悬索桥的结构分析结果更加符合实际情况。

Based on a real event, this film artistically reproduces such a story: a certain prison in Chinese mainland dislocates over ten thousand prisoners serving sentences under an extreme situation of being threatened by a catastrophic flood without any case of escape or death and thus this event has caused a tremendous stirring influence globely.

根据获鲁迅文学奖的报告文学《生死壹线》改编，以真实的事件为背景，艺术地再现了中国内地某监狱在被特大洪水淹没的极其困难情况下转移壹万多名服刑人犯，无壹逃跑无壹死亡，在国际上产生轰动影响的故事。

Aimed at the difficulty to extract the fault information of a low speed shaft in a large gearbox, wavelet analysis was used to realize the local analysis of signals in a time and frequency domain simultaneously. The signals were dissembled to a sieres of compactly supported wavelet bases non-redundantly and without leaking.

针对大型齿轮箱低速轴故障信息难以提取的问题，采用小波分析方法对故障数据进行处理以实现信号在时/频域的局域性分析，将其无冗余、无泄漏地分解到一组具有紧支撑性的小波基上。

And try to find out the effect of TSA on the proliferation and differentiation of rat tracheal stem cell. Methods 1.Preparation of 5-Fu Model and TSA treatment Two weeks" Wistar rats provided by the animal center of the China Medical University. The animals were sacrificed by 10% Chloral Hydrate 0.4ml/100g. Then the tracheas were excised aseptically. Then they were douched with PBS and cultured in 1:1 mix of Dulbecco"s modified Eagle"s medium and Ham"s F-12 medium (DMEM/F12) containing 120 mg/ml 5-Fu and 10% fetal bovine serum for 12h at 37°C. The tissues were then refreshed by culturing in DMEM/F12 containing 10% FBS and 200nM TSA.

1、制备气管损伤模型及剥离上皮取约200克左右的Wistar大鼠，雌雄不限(中国医科大学实验动物中心提供)，腹腔注射10%水合氯醛0.4ml/100g，无菌条件下取出气管，无菌PBS反复冲洗，洗净血液和粘液，置于DMEM/F12培养液中(含10%胎牛血清)，于培养液中加入终浓度为100mg/ml的5-Fu，37℃，5%CO2孵育12小时，弃去上述培养液，换成新鲜DMEM/F12液(含10%胎牛血清)，同时加入终浓度为200nM的TSA继续培养，于换液后3、6、12、24、48小时分别10%中性福尔马林固定，石蜡包埋，制成4μm厚的组织切片。
