Taken together, compared with the susceptible strain, the resistance strai ns have no obvious changes in karyotype but have distinct difference in DNA level, which suggests that insecticide resistance is related to the changes hi gen omic DNA in diamondback moth.

从上面的结果看来，与敏感品系相比，三种抗性品系小菜蛾的核型没有发生明显的变化，但在DNA水平上存在明显的差异，说明小菜蛾的抗药性与基因组DNA的变化有关。

Discrete water drops on the surface greatly reduced the flashover voltage of test sample. The extent of decrease related to the volume, number, conductivity, distribution and location of water drop.

分离水珠的存在大大降低了试品的闪络电压，其降低的幅度与水珠的大小、数量、电导率及分布和位置有关。

"Appeared as early as in the Buddhist translation in the East Han Dynasty and replaced "食" in late Tang and Five Dynasties. The different geographical layout of the glosseme can be a presentation of ...

不同方言相对应的词位区域分布特征可以看作北方官话、近江方言、远江方言在类型特征上的表现，同时反映了源流特征和地域特征。2普通话和方言相对应的义位&吃&在组合关系上存在着差异，这与古代共同语的传承、汉民族义位&吃&义域范畴扩展、不同方言自身整合特点有关。

Parabolic diffusion could describe Cd 2+ desorption kinetics in latosols and not suitable for red soil and goethite and kaolinite.

流出液 pH值的上升反映出土壤表面存在质子的消耗，这可能与硫酸根的专性吸附释放羟基和矿物表面的质子化有关，这在砖红壤上表现得特别明显

The gene has smaller homology with these ACC synthase genes expressed by other inductions.

由于CS-ACSG基因与乙烯的形成有关，因此比较了不同性别表型黄瓜各品种内源乙烯释放和EFE活性的差异，结果表明：CS-ACSG基因与雌性系黄瓜的内源乙烯释放及EFE活性之间并不存在着直接的联系。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

At the core of the document, the need to defend Jesuit's presence at the Court of Mathematics, opens interesting new perspectives on the scientific dimension of the mission and its evaluation among both the Society of Jesus and the European learned élites.

文件的核心——捍卫耶稣会士在钦天监的存在之必要——为我们揭示了有关传教使团科学活动的有趣的新认识，以及耶稣会及欧洲学界精英对它的评价。

The carbonate reservoir is characterized by the fact that the azimuth of fractures is related with structural axis, the developmental extent of fractures and structural location are close related to dip of structure, low-dipping structural axis has not growth fractures. Otherwise, growth fractures, density of fractures are related thickness of layer, more thickness, then less density of fractures. Intra-fracture of layer is main. Some marlstone and anhydrite barriers exist in the reservoir, and become some non-connected oil-water system.

结果表明：碳酸盐岩油藏为裂缝的发育程度与构造位置及构造倾角的大小有关，构造轴部倾角小裂缝不发育，构造翼部倾角大，裂缝发育；裂缝发育密度随着单层厚度增加而逐渐减小；裂缝以层内缝为主，穿层大裂缝少；油藏中存在若干泥质灰岩和膏盐的隔夹层，形成多个连通不畅的油水分布系统。

There is still great uncertainty about the nature of ecological thresholds and how they are related in different spatial scales.

由于生态因子相互作用的复杂性，有关生态阈值的性质及其在不同空间尺度上的联系仍然存在很大的不确定性。

The authors' analysis suggests that there may be five distinct subregions within 8q24, separated by sites of frequent recombination, and each associated with different types of cancer.

作者的分析提示8q24区可能存在5个独立的亚区。这些亚区被频繁重组的位点分离。它们每一个都各自与其不同类型的癌症有关。
