The effect of the natural enemies were assessed according to the analysis, which revealed that the parasitoids played more significant role than the predators, and that Citrostichus phyllocnistoides which had the closest synchrony and sympatry with citrus leafminer P.citrella, should be considered as dominant natural enemy, and be protected and utilized to control the citrus leafminer. Wide niche and distribution as Orius sauteri has, its narrow overlap showed the less close sympatry and synchrony as well as impossibility to control the prey.

寄生性天敌群子强于捕食性天敌群子，表明在自然环境中寄生性天敌群子对桔潜蛾的控制作用强；捕食性天敌小花蝽Orius sauteri虽然食谱生态位宽，但生态位重叠却小，说明这种天敌尽管分布广泛，可在时间和空间上没能有效"跟随"害虫的发生，对害虫控制作用不大；寄生性天敌短腹桔啮小蜂Citrostichus phyllocnistoides与桔潜蛾在时间上的同步性和空间上的同域性均优于其它天敌，为优势天敌，应加以保护和利用。

The normal water level of a reservoir is a key parameter for hydropower station operation. A multi-objective decision-making model is developed by grey correlation analysis, which can effectively treat unquantifiable grey evaluating indicators.

水库正常蓄水位是水电站的主要参数之一，用灰色关联分析建立起多目标决策模型，有效处理了不可量化的灰色评价指标，对三峡水库正常蓄水位方案进行了选择。

Additive effects were predominant, totally explained 75% of the phenotypic variation and often combined with digenic epistasis. Of 12 main QTLs,9 showed Gaoyou alleles decreasing plant height. Most QTLs with QE effects showed ecologically favourable alleles in diverse regions.

株高受多个QTL影响（12个位点具有加性或兼有环境互作效应，5个位点具有互作效应），以加性效应为主，加性效应总和可解释定位群体表型变异的75%左右，并多兼有上位性效应。12个主效QTL中，9个是&高油&等位基因相对&Sollux&有降低株高的作用，大多数加性×环境互作QTL的有效等位基因具有环境选择特异性。

Dissections both posterior and anterior to the mesosigmoid are effective methods to identify and divide the IMV at high level.

结肠系膜后位和前位解剖法相结合，是识别和定位IMV的有效手段。

MRI,being noninvasive,nonionizing,and with multi－ planar capability,proves to be a very useful imaging modality for locating cryptorchism.MRI can provide both anatomic information and tissue characteristics.The optimal imaging planes are the transverse and coronal views.

本组病例证实MRI对隐睾定位是一种非常有效的影像学检查手段，MRI能揭示隐睾的解剖及组织学特征，最佳的成像平面为轴位及冠状位。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
