As far as the marginal effect is concerned, both models show that the variable " rapid expansion of universities " has the highest marginal probability among all factors which have significant impact on overeducation by both models.

在边际影响方面，相同处：「受大学快速扩张影响」、「拥有较多小孩子数」发生超额教育的机率「愈高」；「父母教育程度愈高」、「公部门就业者」、「现职年限愈长」发生超额教育的机率「愈低」。

Well, now I can answer: Although the design life of your house and land have a serviceable life of 70 years, its actual service life of only 30 years up to 50 years, so fuck you oversensitive doing?

那么，现在我可以回答：虽然设计寿命你的房子和土地的使用年限为70年来，它的实际使用寿命只有30年，直至50年，因此，他妈的你多心干什么？

With the extension of fertilization with organic , especially with the combination with organic and inorganic fertilizer,the soil readily oxidizable organic matter increased, while Kos decreased ; The soil active humus content, humus acid and E4/ E6 value were increased , while molecular weight and aromaticity of humus acid were decreased , thus progress to humus formation and quality of organic matter were enhanced.

随着有机肥特别是有机无机氮肥配施的年限延长，土壤易氧化有机质的含量逐渐增加， Kos 下降；提高了土壤松结态腐殖质含量，提高胡敏酸的比例；提高胡敏酸的E4/ E6值，降低土壤胡敏酸的分子量及芳构化程度；从而促进土壤腐殖化进程，改善有机质的品质。

Results Children looked after by grandparents, or the parents brushed their teeth once or less daily, or the parents were packman or jobless had higher dmfs scores.

结果单因素分析显示父母刷牙≤1次／天、父母是个体或无业、1～3岁时主要由祖父母照顾的儿童dmfs较高；父母的口腔健康态度、父母年龄和受教育年限及家庭收入与子女的dmfs呈负相关。

Medline, EMBASE, CBMdisc and other database of clinical trial were searched for Chinese and English language meta analysis and randomized controlled trials. Conference abstract, personal reference lists, reference lists of retrieved studies and some websites were also searched.

联机检索EMBASE、CBM光盘数据库，Medline、CCTR、SCI及相关临床试验数据库，检索年限为2000～2005年3月，手检已获文献的参考文献、会议摘要及相关网站，鉴定中、英文发表的有关随机对照试验。

A study on the anatomical structure and the barbloin's store place of Pulsatilla chinensis of different growth lengths by anatomy and barbloin histochemical localization shows that multicellular nodulos, secretory cavities and secretory ducts in phelloderm and secondary phloem are the primary place of the barbloin substances and the major structural characteristics, wide or narrow of the secretory ducts is related to the growth length, 4 to 5 years old reaches maximum.

利用解剖学和组织化学定位方法对不同生长龄白头翁根的解剖结构和皂苷的储藏场所进行了研究。结果表明：栓内层和次生韧皮部中的分泌细胞团、分泌腔和分泌道是白头翁根的主要结构特征，是皂苷类物质的主要贮存场所；而分泌腔和分泌道的数量及分泌道的宽窄与生长年限相关，4~5年生达到最大值。

On the other hand,the fatigue life increases with the decrease of the modulus of the surface layer in a power function with a negative exponent.

严重的疲劳开裂可以削弱路面的整体强度，并诱发其他类型的损坏[1]，缩短道路的使用年限，导致重大经济损失。

These cycles plus two first-order cycles in the Phanerozoic successions have disclosed that a genetic link may be postulated for individual Earth shells and galactic precessional cycles.The stratigraphic records of the above-mentioned cycles are significant especially for the division of the Precambrian strata with lower stratigraphic resolutions.

尽管对地层记录中隶属不同级别沉积层序的间断面所代表的间断时限的绝对年限还难以精确估价，而建立在岩相及相序基础之上的旋回性地层记录的研究，是从复杂而不完整的地层记录中寻找出更多规律性的有效途径，特别是对生物地层分辨率不高的前寒武纪地层，尤其显得更加重要。

There are a large number of historic heritage buildings and architecturally preservable buildings in Shanghai, some of which have been in use for around 80 years or even over 100 years.

上海市拥有大批历史保护建筑和近代优秀建筑，这些建筑物建造使用年限迄今已达七、八十年以上，有的甚至百年以上。

Friction tests in moving water and field sheer tests and seepage model tests and the effects of seepage defending and rough ratio tests and the capacity of resisting from frozen bulge and ice pressure. 2. Through the series track ageing tests of geosynthetics for 14 years, if the covering is 40cm thick and the initial strength is more than 500N/5cm, the geosynthetics can be used for at least 50 years, most to be more than 100 years. Under the same conditions, the strength and elongation of geotextile are both decrease, and for geomembrance the strength increased in early days. One important ageing index for geomembrance is embrittlement.

2通过工程现场14年的取样，进行老化试验分析，结果显示，土工合成材料在40cm厚以上岩土严密保护的条件下，初始强度大于500N/5cm，使用年限至少可达50年，多数情况可超过100年；在同等条件下，土工织物老化在力学性能上的表现是强度和延伸率都呈下降趋势，而多数土工膜在初期力学性能上表现是强度增加延伸率下降，到后期强度和延伸率才都呈下降趋势，脆化是衡量土工膜老化性能的重要指标。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
