In some areas,the liquid limit and plastic limit has approximate lineal relevant formula , expressed formula as like this ω P=a+bω L.

液塑限试验是土工试验的重要项目之一，塑限试验一般用手工操作、人为因素大、效率低，但局部地区塑限与液限却有如ωP＝a＋ bωL 的近似线性相关公式。

On the base of analysis concerning Tianjing and Tanggo-Xingang soil properties and observation results of settlements, some rules of settlement of buildings in the area were obtained. Final settlements, settlements at end of construction and the time of final settlement were discussed. Tests used for determining paramcters of four models were introduced. The parameters in Duncan-Chang model are determined from isotropic consolidation test and the parameters in Gong-Xiannan model from Ko consolidation tests while the parameters in the model proposedin chapter 2 from the equal increment stress ratio test and ones in the bounding surface model developed in chapter 3 from the effective stress-path of CIU test.

根据天津市区及塘沽新港地区的地基土质情况以及沉降观测资料，分析了该地区建筑物沉降的一些规律，讨论了最终沉降量，完工时的沉降量以及沉降稳定时所需要的时间，介绍了确定各模型参数所需要的试验：Duncan—Zhang模型参数根据等向固结的三轴试验确定；龚晓南Ko固结模型根据Ko固结三轴试验确定；本文建立的非线性弹性模型根据等向增量应力比试验确定，边界面模型参数可根据固结不排水剪切试验的有效应力路径确定。

It also carries on four levels of single-factor laboratory experiments with three sample soils: clay, cohesionless soil and sandy soil, concerning three elements: cement mixture ratio, age, water content in order to find out the contractibility under different test conditions, and also the permeability of locking surface between cement soil and concrete.

试验选择粘土，粉砂土和粗砂土三种土质，采用室内试块试验的研究方法，选择水泥掺入比、龄期、含水量三种因素，分别进行了四种不同水平的单因素试验，研究水泥土在不同养护条件下的收缩性，通过水泥土和混凝土咬合面渗透试验来检验两者咬合面的抗渗性。

In order to complete the investigation, impersonality feasible experiment solutions and devices are designed independently to systemically investigate on activation and transfer characteristic of soil heavy metal under acid rain effect. Primary results are shown as followings:1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation.The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。2、酸雨对盐基离子活化迁移产生的影响勿庸置疑，但是，在盐基离子活化迁移的过程中，并没有出现预想中的重金属元素活化迁移现象，表明土壤中的重金属元素并不如理论分析的那样对酸雨沉降反应敏感。

Methods The stablishment of lymphoblast cell lines was by EBV-immortalization and subtyping of the cell lines by cell fusion, mytomycin C inhibition analysis and/or immunoprecipitation and Westemn blot.

方法将我国3例FA患者外周血细胞用EB病毒活化法建立原始B-淋巴细胞系，采用丝裂霉素生长抑制试验和细胞融合后MMC抑制试验的互补试验进行分型；利用单克隆抗体免疫沉淀法和Western blot法进行分型。
