Connected with cross section patterns of freeway, the design method of drainable base course system and edge drainage system which meet to request are given too. The aggregate grading and mixture ratio of porous cement-treated macadam are obtained based on accurate survey on material properties and lots of laboratory experiments. After the construction of experiment road, a summary of mixing, spreading, roller compaction and maintenance process about subsurface drainage system is made, and the analysis on the cost of construction about drainable base course is also carried. According to the test of coefficient of permeability, porosity and strength of compression about local test samples and core samples, the paper concludes that main performance index of subsurface drainage system has achieved the design anticipated effect.

The toxicity of spent potliner is discussed in this paper according to the research on main constitutes,microstructure,tiny section components,ash content and hydrating reactivity of SPL. The result indicates that the toxicity of SPL mostly rests with its leaching toxicity,contaminates in SPL are mainly dissolving fluorides and cyanides,these contaminates mostly come from electrolyze which infiltrate into the potliner and cause erosion,contents of dissolving F— and CN— in SPL are far more than the permitted discharge in national standard. SPL, which seriously does harm to eco-environment is classified as hazardous solid waste and should be detoxified as soon as possible.
本文从废槽内衬的物相组成、微观形貌、微区成分、灰分、水化反应性五方面研究了废槽内衬的危害性,结果表明,废槽内衬的危害性主要在于其浸出毒性,毒害物质主要是可溶氟化物和氰化物,毒害物质主要来自于电解质对内衬的渗透、侵蚀,废槽内衬中可溶F—和CN—的浓度远远高于国家标准规定的允许排放量,因此废槽内衬被认定为固体危险废弃物,严重危害生态环境,必须进行无害化处理。

Through comparing the opinions of different scholars it illustrates the author"s comprehension towards the concept of law explanation and focuses on the principle of it, namely the principles of law objectivity, legitimacy and rationality.The second section of this paper introduces the meaning of the explanation of administrative law and its basic category as well. Firstly, it analyzes academic area"s two riftses toward this concept: the boundary question between legislation explanative and administrative explanation; the question of which is the main principle of administrative explanation and putting forward the concept of it; the illustrations made by special state administration towards the meaning of laws, regulations and rules according to the laws.

In this paper, the biological characteristics of florescence, spikelet and inflorescences structure, morphogenesis formation of inflorescence, megasporogenesis and the development of female gametophytes were studied systematically by using anatomy structure, scanning electron microscopic and paraffin section methods. The results were as followed:(1) Phyllostachys praecox was the bamboo flowering fragmentarily; the cultivation changed the characteristic of flowering; the plantlets of flowering were complex and splitted into three kinds: the plantlet flowering before continued flowering; the plantlet flowering before stopped flowering and the plantlet changed into flowering. The inflorescence of Ph. praecox was indefinite inflorescence or called false inflorescence, and actually it was flower stress structure. Its basal unit was pseudospikelet with two kinds: apical spikelet and lateral spikelet. The floret had one lemma, one pelea, three stamens, one pistil and three lodicules.

In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.
