The behavior of passing solitary waves through the region of grain boundary has been investigated on the basis of the molecular dynamics method. It has been shown that solitary waves initiated by compression and shear loading have a different interaction with the grain boundary region. The possibilities of using solitary waves for nondestructive testing of materials, in particular, for testing the quality of coatings, for testing of accumulation of microdamages, etc. have been noted.

通过对过去40年收集的西伯利亚北极地区水文地球化学数据进行分析及综合解释,对数据进行了分类、评价和统计分析,评估区域背景值和异常值,估算水源之间接近程度的各种相关系数。西伯利亚沉积盆地的古水文地质重建表明,油气藏的水体有3种成因类型:(1)海相沉积过程中形成的水体;(2)渗入盆地内并经历了各个地质时期表生作用的大气降水成因的水体;(3)烃类混合物冷凝形成的水体。油气藏的水文地球化学模式受控于水-岩-气-有机质体系漫长的地质演化过程。西伯利亚北极地区沉积盆地内分布总矿化度为0.2~350.0 g/L的含氯化钠-碳酸氢盐、氯化钠、氯化钙地下水和其他类型的地下水。通过对西伯利亚北极地区地下水的对比分析,发现含有氯化钠组分的样品总矿化度超过250 g/L,表明卤水的形成与蒸发岩的浸出有关。水文地球化学数据分析显示,地下水的成分随其演化而发生非常大的变化,阿纳巴尔—拉普帖夫、西西伯利亚等盆地中生界的地下水处于其化学演化的初始阶段。

以往瞬变电磁法在探测金伯利岩简中得到广泛应用，尽管在这方面做了大量的实践工作．但其效率不高，效果不令人满意。与围岩相比．金伯利岩筒表现为低阻，而其上覆地层表现为各向异性．因此出现了由金伯利岩筒引起的低阻异常。目标体的这些特征要求所用的电法勘探的资料解释要可靠，并且所用方法的张量修正优于它的标量修正。

The response of three-dimensional sample of Al, containing vacancy complex, under shear loading was simulated. The molecular dynamics method was used and interaction between atoms was described on the base of pseudopotential theory Solitary waves were generated in the sample under mechanical loading. Their interaction with the vacancy complexes was shown to be able to initiate hot spot in that local region of the complexes. Some parameters of the hot spot as well as solitary waves were calculated. The initiation of the hot spot is accompanied with sufficient local structural relaxation.

本文介绍了AMT(音频大地电磁测深)法在雅库特和俄罗斯的Archangelsk金刚石矿区勘探中的应用.文章描述了金伯利岩岩脉的位置和形状、电性参数、围岩和上覆岩层特性.金伯利岩矿区位于易于被AMT方法确定的参考导电层之上,或者在高阻层之上.金伯利岩岩脉发育在金伯利岩矿区良导的局部边缘地区.这些良导区与地堑构造有关,其边界与基底和厚层沉积覆盖的弯曲褶皱相一致,并具有强破裂和利于金伯利岩岩浆渗透的特点.依据AMT数据,可很好地确定局部良导区,并作为最有远景的矿脉发育区.利用AMT数据可确定断裂带和区分矿区的构造断层.金伯利岩控制的断层一般被圈闭的岩墙充填,易于被磁法资料确定,而金伯利岩的围岩断层不包含圈闭的岩墙,由磁法难以测量,因此就可较好地确定金伯利岩.本文给出了由沉积层覆盖的简单地质条件下发现岩脉的例子,也介绍了包含几种不同类型金伯利岩如导电的斑状金伯利岩、并被圈闭和厚层沉积覆盖的复杂地质条件下确定岩脉的实例.

＜正＞One of the important problems of modem manufacture is improvement of technical and economic parameters of welded designs on the basis of reduction in their specific metal consumption, increase in operational reliability and durability. High-strength alloyed steels with a liquid limit 550…950 MPa （30XΓCA, 12X2HhA. etc.） possess a high complex of operational properties and are used for manufacture of crucial welded products. They provide high durability of design at simultaneous reduction in its metal *** main difficulty at welding these steels is prevention of formation of cold cracks in metal of a seam and zone of thermal influence. Solving this problem becomes complicated because welded connections should possess required operational properties in after welding condition without more heat *** resource-saving technology of welding of multilayered connections with slot-hole cutting from steel 30XΓCA by a stationary arch in conditions of two-jet gas protection in CO2, without preheating and subsequent heat treatment is developed. The multilayered welded connections received by developed technology possess high enough and stable operational *** carried out microstructural analysis of samples has shown presence of fine-dyspersated structures of metal in seams with implicitly expressed welded zone, i.e. there is a smooth transition from metal of a seam to the basic metal that provides high serviceability of welded connection. It is proved by a high value of impact strength of samples with a cut in zone of thermal *** preheating and subsequent heat treatment from technological process of welding of multilayered welded connections of steel 30XΓCA allows to save 3-4 m3/h of combustible gas （acetylene, natural gas） and 3-4,5 m3/h of oxygen necessary at local heating of welded products. The economy of gas and oxygen at welding one running metre of multilayered welded connection makes 14,58 roubles in the prices of 2002. Du
