The study indicates that the frost heaving character of the meal sand is decimus of silt clays. And its frost heaving quotiety is seldom influenced by the different freezing end temperature and water content. Thus the surroundings influence is in the small area when the artificial freezing method is used in sand and no-stickiness soil.

研究结果表明粉砂冻胀率是淤泥质粘土冻胀率的十分之一，冷端温度、含水量两个因素变化对其冻胀率几乎不产生影响，因此在砂性等无粘性土中应用冻结法对周围环境危害较小。

This paper analyzes the causations of frost heaving of road and conformation building in cold area.

对寒冷地区出现的道路、构造物冻胀现象进行了分析，阐述了冻胀产生的原因，并提出了几项防止冻胀的措施。

This paper expounds the basic principles and basic features of the frost heaving of lined canal, and introduces the calculating method for the frost heaving resistant and the selection of the measures for frost heaving resistant .

阐述了衬砌渠道冻胀的基本原理及基本特征，介绍了衬砌渠道抗冻胀计算方法及防冻胀措施的选择。

When outside stresses counteract the momentum that is necessary to transfer the unfrozen water, frost heaving will no longer produce, and frost-heaving forces will no longer develop.

冻胀力的发展同时也取决于水分向冻结锋面的迁移量，当外压力抵消水分迁移所需要的动力时，此时冻胀不再产生，冻胀力也将不再发展。

Moreover, frozen restraint between the slate and the underneath frozen soil is an important condition for frost heaving of the slate.

另外 ，渠道边坡衬砌层和其下冻土层之间冻结约束的存在与否是边坡衬砌层会不会受冻胀力的必要条件，若此约束存在，则可能受冻胀力，若此约束不存在，则其不可能受冻胀力。

The hydraulic loading system is developed and used to study the frost heaving characteristics of the subgrade soils under dynamic loading in closed system and open system . On the base of these work, the conclusions are as follows:1. Because of the the fine-grained fill, the frost deformations of Beijing-Baotou railway subgrade and Baotou-Lanzhou railway subgrade are holistically irregular, and great discrepancies exist among the frost heavings of subgrade at different sections.

本文根据冻害较严重的京包铁路、包兰铁路的气候、地质条件的调查和路基冻胀变形监测，结合路基土的性质对京包铁路、包兰铁路的冻害给出了评价；为了模拟振动荷载作用下土的冻胀，研制了液压动力加载系统；在室内采用实验方法对列车动荷载作用下包兰线路基粉质土在开敞、封闭系统下的冻胀特性进行模拟。

Some expanding structures of tube to tube -sheet used in HP heater have been described in the article.

文章介绍了高压加热器几种管子管板胀接结构，对不同胀接手段进行了比较，分析其优缺点；对液压胀接的原理和计算公式以及管子管板液压胀接试验过程进行了表述。

The reverse force self-expansion rivet as one fastener part has one small head and one small-diameter neck in the root part as well as one integral expansion sheet with the same diameter as the shaft in between.

目前国内外所使用的《胀钉》是螺杆式的《他胀钉》，它构件多，成本高。因此，本人发明了简易的《反力自胀铆钉》来满足各种材料的铆制紧固上。其结构特点是在钉杆根部有直径偏小的颈部和小头，还在其间有与杆同径连体的胀片。

Installation of two outer openings each staggered 180b, the inner and outer openings staggered opening 90b, and pin the three rings with a fixed, outer and inner expansion force in self-expansion force of working together, close to the surface of the pump cylinder run, inflation is not only the axial ring sealed, and the radial seal Ye Hao, it prevents micro-fine sand and into the axial friction pair, can also prevent the micro-fine sand and into the internal voids in the inner ring 3, the operation will not impede expansion ring breathing.

安装时2个外环开口互错开180b，内环开口与外环开口错开90b，并用销钉将3个环固定，外环在自身胀力和内环胀力共同作用下，紧贴泵筒内表面运行，胀圈不但轴向密封好，而且径向密封也好，故阻止微细砂进入轴向摩擦副，也可阻止微细砂进入内环3的内部空隙中，不会阻碍胀圈运行中呼吸。

This paper analyzes on the reasons of the seamless line track buckling and the premonitions before buckling, and advances some measures for preventing the track buckling and the treating methods adopted after the track buckling appears.
