The pin top for pre-selecting is welded on the bottom part of the bracket of core drill, the pin top is in favor of the localization of drilling hole, at the same time, it can overcome the reversal angular force acted on the core device, it enhances the rigidity of the whole mechanism.

起预定位作用的尖顶焊接于取芯钻机的机架底部，尖顶有利于钻进初始阶段时钻孔的定位，同时还能够克服作用于取芯器的反转矩，提高了整个机构的刚度。

This article mainly introduced three aspects of researches on emotion and memory: the role of emotion in memory, the way of emotion effects on memory and brain regions involved in the emotion-memory interaction. The affection of emotional arousal to amygdale, and the interaction among amygdale, medial temporal lobe and prefrontal cortex were specially emphasized

该文简要介绍了近年来国内外有关情绪和记忆的研究，着重讨论了情绪在记忆中的作用、情绪影响记忆的途径以及参与情绪和记忆交互作用的脑区；特别强调了情绪唤醒对杏仁核的影响，以及杏仁核与其它内侧颞叶结构和前额叶的相互作用。

The problem is how to consider the relativistic corrections to this potential. Adopting the assummation that the quark interaction is the sum of the usual one-gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2/c2to the Cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one-gluon direct exchange at short distances.

采纳库仑势源于单胶子直接交换，而线性禁闭源于标量和矢量的混合，同时考虑在短程区域与单胶子直接交换起同样作用的同味正反夸克的湮灭，构造了静态夸克-反夸克势到v~2／c~2级次的完全相对论修正，并拟合计算了重介子偶素的能谱，讨论了相对论修正对重介子偶素能级分裂的作用。

In recent years, much attention has been attracted to the 1D strong correlated system with two mechanisms of opening gaps. The models include:(1) the frustrated spin-Peieds system,(2) the 1D Hubbard model with a staggered potential,(3) the antiferromagnetic Heisenberg chain with Dzyaloshinskii—Moriya interaction,(4) the spontaneously dimerized s=1/2 antiferromagnetic chain in a staggered magnetic field.

特别是近年来，具有双能隙机制的一维强关联系统引起人们的关注，这些系统具体包括：（1）具有阻挫作用的Spin—Peierls系统；（2）电荷转移型Hubbard模型；（3）具有Dzyaloshinskii—Moriya作用的反铁磁海森堡链；（4）在交错势场中具有自发二聚化的S=1/2的反铁磁海森堡链。

This is a review of recent studies on the relationship between fire and invasive plant species.

在植物外来种与火生态因子的作用研究中发现，火与外来种的关系随物种生物学特性、火作用的时间、频度、强度不同而不同，火有时会有效地抑制外来种的生长和入侵，有时会促进一些外来种的生长和入侵。

To a certain extent, the oxidation of sulfide and releasing of heavy metals were controlled by the chemical characteristics of hydrological environment. This process gave rise to the formation of the metastable secondary metal-bearing minerals on the surface of sulfide in the sediment.

河流水体环境化学性质影响了沉积物中硫化物氧化作用的氧化速率，导致硫化物表面亚稳定的次生富重金属矿物相的形成，对水体质量的自净有一定的作用。

There mainly develop 5 types of pre-tertiary structural style that are extension structure, compression structure, strike-slip structure, negative inversion structure and sliding structure in the Bohai Bay region.

渤海湾地区前第三系的这种构造样式分布格局可能是印支期华北板块与北部的西伯利亚板块、南部的扬子板块先后闭合碰撞以及燕山中、晚期滨太平洋构造域影响作用不断增强和深部岩石圈的大规模减薄作用的结果。

The statistical result of the distribution of fractures and vugs indicates that high mud content is unfavorable for karstification, and the sequence boundary has an obvious controlling effect on the vertical distribution of dissolved pores, and a weak affection on the distribution of fractures.

层序分析结果和缝洞统计规律对比表明：较高的泥质含量不利于溶蚀作用的发生；层序对溶孔的纵向分布有着显著的控制作用，而对裂缝的分布影响较弱。

The OXPHOS electron transfer chain (mitochondrial respiration chain) is located on the inner membrane of mitochondrion and comprising of four large trans-membrane protein complexes (mitochondrial respiratory Complex I, II, III and IV) as well as ubiquinone between Complex I/II and III and cytochrome c between Complex III and IV.

摘 要：线粒体作为真核细胞的重要&能量工厂&，是细胞进行呼吸作用的场所，呼吸作用包括柠檬酸循环和氧化磷酸化两个过程，其中氧化磷酸化过程的电子传递链位于线粒体内膜上，由四个相对分子质量很大的跨膜蛋白复合体(I、II、III、和IV)、介于I/II 与III之间的泛醌以及介于III 与IV之间的细胞色素c共同组成。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
