However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...

Besides, the detection of a number of target navigation parameters can be estimated. The goal of this paper is to present a PCA electric field algorithm for calculating the target headings, size/velocity rate and port/starboard location in relation to the electric sensor axis. This PCA algorithm is based on the simultaneous analysis of the three components （longitudinal, athwartship and vertical） of the electric signature in order to compare the time evolution of their waveforms as a way to determine the target parameters.

此外，还可估算探测大量的目标航行参数：目的是提供一种主分量分析电场算法，以计算相对电场传感器轴线的目标航向、尺寸／速率、左右舷位置：此种PCA算法基于同时分析电场特性的3个分量，以便比较这些波形随时间的变化，作为确定目标参数的方法。

While statistical techniques have been optimized to improve model accuracy, less focus has been given to the question: How does the autecology of a single species affect model quality We compare a direct modelling approach versus a cumulative modelling approach for predicting plant species richness, where the latter gives more weight to the ecology of functional species groups.

当统计技术有效改善模式的正确性时，较少注意已存在的问题：个体生物学中，单一物种是否会影响模式特性我们比较直接模式与渐增模式在植物物种丰富度的准确性，后者的权重以生态功能物种分群。

In this study, real-time PCR technology was used to dectect the expression of PRL mRNA and its receptor in the reproductive tissues,which is hypothalamus-pituitary-ovary-oviduct four important tissues. The aim was to compare the difference of PRL mRNA expression in the different state of ovulatory, broody and after broody, and to analyse the relation between expression and reproduction.

本试验利用real-time PCR技术检测雪山草鸡下丘脑、垂体、卵巢、输卵管四个繁殖轴组织中PRL基因及其受体的表达量，以确定处在生产、抱窝、醒抱三个不同状态母鸡PRL基因表达的差异，并分析基因表达量的差异与生产性能的相关性。

It was emphasized that GB3838-2002 not only need to pay attention to the full treatment of wastewater and rainwater but also the proper disposal of treated wastewater which meet the national discharge standard GB18918-2002 but still contain significant amount of pollutants if compare with the national surface water quality standard GB3838-2002. To the brooky region of Jiang-Zhe Plain, the discharged pollutant loads still significantly exceed the environmental capacity of the receiving waters even if all treated wastewater meet the first grade B limits of GB18918-2002, and the water pollution problem still cannot be really eliminated.

通过比较分析，我国现行的城镇污水处理厂污染物排放标准GB18918-2002和地面水水质标准GB3838-2002，明确提出，相对于这一区域的地面水环境质量而言，不但雨污水必须得到充分有效的净化处理，达标排放的污水中也仍然含有总量不容忽视的污染物质；对于江浙平原河网地区，即使全部城市污水都达到GB18918-2002中一级B的要求，排放的污染物负荷仍然会明显超过受纳水体的环境容量，水污染问题仍然难以真正消除；达标处理水的处置与利用问题值得特别的关注与探讨。
