By adding some fluorescence group in the reaction,we can utilize the fluorescence signal to accumulate and monitor the whole PCR process,and finally through the standard curve,we could analysis the unknown sample.As this technology has the characteristics of strong peculiar,high sensitivity,fine repetitiveness and accurateness,fast and totally closed raction,so in diagnosing animal virosis,this technology not only can measure the power and distribution of pathogen infection in the organism,and also it still has sensitive,fast,convenient characteristics.

该技术实现了PCR从定性到定量的飞跃，同常规PCR法相比，该方法特异性和可靠性更强，能实现多重反应，且采用了完全闭管检测，不需PCR后处理，有效解决PCR污染问题以及EB对试验人员的伤害；再配以相应的荧光PCR仪，使整个PCR过程实现自动化，加之具有耗时短，操作方便等特点而备受推崇，因而广泛应用于基因表达研究、转基因产品安全检测、单核苷酸多态性研究及病原体检测等领域。

In 2003, scientists studying a volcanic vent 2 km under the sea and discovered a single-celled organism that can cope with temperatures of 121°C. They named it "Geogemma barossii".

2003年，微生物学家在海底两千公里深处、温度高达121°C的火山口发现了一种单细胞生物体—超嗜热菌。

One day he told us that his Volkswagen was a living organism.

一天，他对我们说，他的大众汽车是一种有生命的生物体。

In 1942, Conrad Waddington coined the term "epigenetics" to describe this idea that an organism's experience may cause its genes to behave (or "express themselves") differently.

在1942年 Conrad Waddington发明了表观遗传学这一术语来描述生物体所经历的后天环境能够显著影响内部基因的外在表现。

Whitehead believes that universe is a vivid, living organism, which exists in the eternal creation and process.

怀特海认为，宇宙是活生生的、有生命的机体，它处于永恒的创造过程之中。

The SOD and the LDH-1 activities and EST (R_f=0.17 and R_f=0.72) at 1℃weresignificantly higher than the values of the room temperature(P＜0.05), but the total enzymeactivities of LDH, G6PDH and EST at room temperature and 1℃were similar(P＞0.05).This showed well-developed anoxia tolerance of the Heilongjiang wood frog to maintainplasma viability when low temperature interrupts the delivery of oxygen and substrates. LDH-1rose significantly avoided the liver lactic acid accumulation that may created the liver to bewearied. EST (R_f=0.17 and R_f=0.72) rose may enhance the ester metabolism to offer muchenergy. These showed steady metabolic rate and relative stable organism environment of theHeilongjiang wood frog to survive under low temperature.Native PAGE separated proteins of liver tissue successfully on the better condition is 6％final gel concentration and there were 15～19 bands identified on this condition.

同功酶电泳图谱显示，1℃组与室温组黑龙江林蛙肝脏LDH酶活性差异不显著，均以LDH-5为主，但1℃组LDH-1显著高于室温组(P＜0.05)，推测黑龙江林蛙为适应低温低氧环境，增强LDH-1酶活性以较好的利用乳酸，避免因大量乳酸形成造成肝脏疲劳；而1℃组肝脏G6PDH酶活性无显著变化，进一步说明低温条件下葡萄糖戊糖途径和糖酵解作用的互相协调，维持机体代谢的稳定；1℃组和室温组EST总酶比活力无显著变化，但1℃组中R_f=0.17和R_f=0.72的EST同工酶显著升高(P＜0.05)，推测在低温条件下黑龙江林蛙可能通过选择性增强部分酯酶同功酶活性，增加肝脏酯类物质代谢，为机体提供维持生命必需的最低能量。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
