较弱的

ACTH〓 at concentration of 10〓-10〓 had no significant influence on the saturation curve, Scatchard plot and Hill plot of 〓-DAGO binding to rat brain membrane.

〓在〓范围内对〓的饱和曲线，Scatchard图形及Hi11图形没有明显的影响；但在较高浓度时可以完全取代〓与其受体的结合，〓为37.1±21.8μmol/L，其抑制μ配体〓结合的强度与δ受体的配体DPDPE和κ受体的配体U50488H大致相当，只是稍弱一些，分别是它们的1／8和1／4。

Within the WBEPM theory,the transition probabilities and oscillator strengths of some heavier and light atoms and ions are investigated.We also used the conceptions of spectrum-level-like series and iso-spectrum-level series to study the energy levels of some atoms.Based on the previous work,we used double generalized Laguerre polynomial to calculate the value for the ground-state energy of He atom.

本论文在郑能武教授提出的最弱受约束电子势模型理论基础之上，对若干较重和轻原子离子的跃迁几率和振子强度作了研究；引入类光谱态能级序列的概念和等光谱态能级序列的概念研究了一些原子离子的能级性质；并在前人工作的基础上用双广义拉盖尔函数对氦原子的基态能量做了计算。

Because of the nondirectional property of ionic bond and the fully delocalized property of pi electrons on carbon layers, translation will not change the electronic structure of carbon layers, resulting in that A-GIC and AE-GIC hare quite good lubrication as well. The electrons come from metals mainly transfer to the delocalized pi orbitals of carbon layers, and the increase of delocalized electrons will make metal graphite intercalation compound more electro-conductive than graphite itself. Because ionic bond between metals and carbon layers is weaker and its lattice energy is much less than that of typical NaCl crystal, so metals could be left from interlayers. The Mulliken populations of C-C in intercalation compounds are smaller than that of graphite, and the HOMO energy level of GIC is higher than that of graphite too. These Lead to that GIC will easier be oxidized.

由于离子键没有方向性，又由于碳层中的π电子是充分离域的，所以碳层不会由于平移而改变其电子结构，金属石墨层间化合物仍具有很好的润滑性；金属失去的电子主要转移到碳层的离域π轨道中，碳层离域电子增多使金属石墨层间化合物的导电性比石墨增强；金属与碳层间的离子键强度比较弱，其晶格能远小于典型的离子晶体，因而金属易从石墨层中脱出；金属石墨层间化合物中的C-C间Mulliken布居值小于石墨中C-C间的值，且金属石墨层间化合物的HOMO能级也高于石墨的HOMO能级，所以石墨层间化合物中的碳原子较石墨更易被氧化。

BACKGROUND: Soft-start is a newly photoactivation mode, which has certain effect on composite resin. However, previous study mainly concentrated on the conventional resin-based composites, the reports regarding soft-start on packable resin-based composites is poorly understood.

背景：弱光启动是近年来应用于临床的新的固化方法，其对复合树脂的性能具有一定的影响，以往国外的研究主要是针对通用型树脂进行的，而对可压型树脂的研究报道较少。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

Firstly, we summed up the process and results of historical research. And then we classified the action morpheme and the noun morpheme. Based on the classification, we analyzed noun morphemes in order to find which kind of noun morpheme is strong to unite and which is the weak ones to centre around the action morpheme. Then we stated, analyzed and accounted for the usage of different semantic categories used in the line situation. We found that action morpheme combined into one by moving the line word was the main line and the main format, and explored and analyzed the role of analogy of noun morpheme line to other formats. Line formation of the word has its own reasons, so the article concluded by examining the formation of the line words' language, social and other reasons at last.

文章着眼于对动、名语素组合成的离合词的语义构成进行分析，探讨了动、名语素组合成离合词的语义选择规律，以动、名语素的语义分类为基点，在分类的基础上，以动语素为中心，分析围绕动语素的名语素义类，分析哪些义类名语素和动语素组合成离合词的能产性较强，即组合的周遍性和数量频度上是最高的，哪些义类组合成离合词的能产性比较弱，试图寻找动语素与名语素组合成离合词在义类上的能产性和周遍性，然后再对不同语义类组合中离合运用的情况进行统计、分析、说明。

In view of these, the second part of this paper presents two sufficient conditions and two mixed type duals for the generalized fractional programming only under-convexity assumptions. These sufficient conditions apply to a broader class of mathematical programming problems.The results about weak duality, strong duality and strictly reverse duality arealso presented under more suitable conditions.

鉴于此，本文的第二部分，我们仅在函数—凸性假设下，给出了广义分式规划的二个最优性充分条件，这些充分条件较文献中的相关的条件有更广泛的适用性；同时还给出了混合型对偶，并且在适当的条件下，给出了相应的弱对偶定理、强对偶定理，以及严格逆对偶定理。

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.

为研究湿地松半同胞家系光合色素对水分逆境的响应，采用盆栽试验和吸光度测定方法，以湿地松普通种子为对照，测定了七个湿地松优良半同胞家系在弱度水分胁迫（土壤相对含水量为55%~60%）、中度水分胁迫（土壤相对含水量为35%~40%）和强度水分胁迫（土壤相对含水量为20%~25%）条件下的光合色素，对湿地松优良半同胞家系在不同水分胁迫条件下的光合色素进行了研究，结果表明：无论是不同水分梯度还是不同家系水平，Chl、Chla、Chlb、Chla/Chlb、Caro、Caro/Chl均有极显著差异；从正常水分至水分胁迫初期Chl、Chla、Chlb、Chla/Chlb稍微下降，后随着水分胁迫程度的加深下降较快，从正常水分至水分胁迫初期Caro、Caro/Chl先稍微下降，胁迫中期上升，胁迫后期下降；所有半同胞家系的Chl、Chla、Chlb、Chla/Chlb、Caro高于普通种，在水分胁迫条件下家系464、1027的Chl、Chla、Chlb、Chla/Chlb、Caro高于家系的平均水平，家系609、46的Caro/Chl值高于家系的平均水平。

As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。
