Theorem of mean significance: The application derivative research function's nature wants directly or indirectly with the aid of Yu Zhongzhi,Specially Lagrange theorem of mean,Here is mainly from the equality proof, the inequality proof, existence asks some limits, the determination equation root and so on five aspects to carry on the discussion,so, The theorem of mean is transforms as the function in the sector research important tool, Must bring to the enough attention in the middle of ours study and the teaching.

中值定理意义:应用导数研究函数的性质都要直接或间接地借助于中值,特别是拉格朗日中值定理,这里主要是从等式的证明、不等式的证明、求一些极限、判定方程根的存在性等五个方面来进行讨论,因此,中值定理是转化为函数在区间上的研究的重要工具。在我们的学习与教学当中要引起足够的注意。

In§5.4,we discuss the hypothesis test problemwhen the location and scale parameter may all change.

5.3讨论尺度参数变点的假设检验问题,引述Wangand Bhatti(1998a)的结果,利用Csorgo and Horváth(1997)的定理,对于Wang andBhatti(1998a)提出的检验统计量〓,其中〓,我们获得了〓的大样本性质,即对于一切实数x〓11进一步地,给出变点〓的估计〓,利用Csorgo and Horváth(1997)的推论1.6.2,我们讨论了变点估计〓的渐近性质,由此,可以给出变点〓的区间估计,〓12其中〓,〓满足〓和〓,这里〓为〓的分布函数。

Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

结果表明:(1)在调查的8个急尖长苞冷杉林样地内共有植物58种,分属于36科53属,其中植物较多的科有蔷薇科8种、百合科5种、杜鹃花科5种、毛茛科3种、菊科3种、柏科2种、忍冬科2种、伞形科2种,其余的28科各只有1个种;(2)物种科、属、种数、Margalef指数D(下标 M与海拔存在显著的负相关性(P.05),在分布急尖长苞冷杉最低海拔3600m处出现物种丰富度的最大值;(3)多样性指数与海拔之间有极显著的负相关性(P.01),并且在3700~4100m之间多样性指数保持稳定;均匀度指数与海拔梯度之间存在负相关性,但不显著;(4)Jaccard指数C(下标 j在海拔3600~4100m随海拔的升高而升高,在生境过渡带的4100~4200m之间Jaccard指数C(下标 j较低;Cody指数β(下标 c随海拔的升高呈下降的趋势,但在4000~4100m和4200~4300m 海拔区间出现2个低谷;(5)最大树高H(下标 max和最大胸径DBH(下标 max与海拔之间存在显著负相关性(P.05);胸高断面积之和和立木密度与海拔之间存在负相关性,但不显著。

It is found that: the standard Model can be used to predict flows at the station and resultant velocity and temperature field under some reasonable presumptions; the impact brought by stopcock wind is variable according to the different tunnel structures; the temperature of is related with the distribution of heat load; the VAV system has advantage in energy saving, but when the air volume reduced to a certain degree, we should consider the alteration of rising the temperature of supply air, and increasing the quantity of it.

研究表明:采用合理的假设,标准的湍流模型能够较为准确地模拟和预测地铁站台的温度场与速度场;活塞风对站台的影响随区间形式的不同而不同;空调送风温度的设定与负荷的分布情况有密切的关系;针对站台空调季全天的负荷变化,VAV环控方案可以达到节能的目的,但在风量过小时,适当考虑采用提高送风温度,加大送风量的方法进行局部的调整。

Pit corrosion is a main kind of localized corrosion. The process of forming pit corrosion includes three stages-formation of pit source, development of pit cave and forming occluded corrosion cell. Molybdate series inhibitors can be inhibitive, for it can control three stages of pit development. First, there is apparent synergistic effect between molybdate and phosphate, which can suppress formation of pit source. Second, there is apparent passivation of molybdate inhibitor according to electrochemistry analysis, which let oxidation film in unoccluded cave repassivate.

首先,钼酸盐与磷酸盐或硅酸盐复配的缓蚀剂具有较理想的缓蚀性能,并且有明显的协同作用,从而能抑制部分点蚀核的产生;其次,钼酸盐复配缓蚀剂的使用,从电化学的角度分析,具有明显的钝化性能,且钝化区间较宽、维钝电流密度较小,从而能使未封闭的蚀孔或点蚀核附近的氧化膜再钝化,得到有效的修复;最后,对于还有部分蚀孔发展成为闭塞腐蚀电池的情况,钼酸盐、磷酸盐能进入蚀孔内部并且在酸性条件下生成铁钼磷酸盐,从而有效地减缓了点蚀的恶化,抑制了腐蚀的发展。

Based on the deep foundation pit project of tunnel in Nanjing metro west extending line, the supporting methods of the bored pile biting into deep mixing pile in soft soil are discussed. The key construction techniques and monitoring results for the supporting form in watered and soft soil bed are expounded. The ability of resisting seepage must be considered when insertion depth of supporting structure is designed, which may also prevent the skirting from losing its stability.

以南京地铁西延线区间隧道的深基坑工程为背景,对软土层条件下的钻孔桩咬合深搅桩的支护方法展开探讨和研究,著重阐述含水软土层中该围护型式的关键施工技术和监测结果,指出在设计围护结构插入深度时必须考虑抵抗渗流破坏的能力,同时安全的插入深度也是防止维护结构&踢脚&失稳的保证。
