The instructive conclusion was: 1 under the vertical loading, the shear-lag effect was produced badly, more severer under concentrated loading than under uniform loading .2 the longitudinal bending deformation of the beam flange was true of the imitating plane assumption of deformation . 3 the width length ratio was confirmed as the first factor working on the shear-lag effect among all the geometric parameters;4 the shear-lag coefficient of simple-supported box-girder was severer than the continuous box-girder, the shear-lag effect in the inner supported section of continuous beam was much more severer, we need paying more attention for it in designing. 5 the non-liner characteristics of material deformation have littlie influence on shear-lag effect in BGCW. 6 the experiential calculating formulation and calculating diagram for the effective flange width was raised with the only factor of the width-span ratio., but the primary location of axis of bending moments should not be changed while calculating the inertial moment .
研究认为:1室内模型试验和空间有限元分析结果均表明波形钢腹板组合箱梁在竖向荷载作用下,翼板出现了典型的纵向应力剪滞效应。2在竖向荷载作用下,截面高度上各点纵向正应变分布认为可符合"拟平截面假定",以此作为波形钢腹板组合箱梁抗弯计算的基本假定。3箱梁宽跨比是影响波形钢腹板组合箱梁翼板剪滞效应的主要因素。4连续波形钢腹板组合箱梁的翼板剪滞系数大于简支梁,且连续箱梁内支点截面翼板剪滞效应相当严重,对此需十分重视。5当混凝土翼板受力由弹性阶段进入弹塑性阶段时,材料的非线性特性对翼板的剪滞效应影响甚微。6提出了根据组合箱梁的宽跨比参数来计算翼板有效宽度比的经验公式和计算图表,但箱梁截面抗弯惯性矩的计算不应改变原先的截面中和轴位置。

In order to reduce calculation error, the frequency distribution of average values is used to compute the mixed distribution's digital features of each component distribution, thereinto, the number of the component distribution is determined by AIC, choose the number that meets the minimum value of AIC as the component number of mixed distribution, and the other parameters are estimated by EM algorithm; Secondly, because each component distribution is corresponding to a kind of major gene genotype, according to the values of the average and variance of the each component distribution, we can use the limit error of the normal distribution to plot each individual into the correspondent component distribution, namely into correspondent major gene genotype. Then we regard each major gene genotype as a treatment level of one-way analysis of variances, and the one-way multivariate analysis of variance is carried out to calculate the covariance matrix of major gene effect, covariance matrix of polygene effect, covariance matrix of environment effect and so on; At last, combining the weights of the each component distribution of mixed distribution, we can calculate the variance of major gene effect, the variance of polygene effect, environmental variance and the genetic gain of the quantitative trait.

Based on the analysis of their stomach contents, their diet composition was assayed. The three fishes" feeding rhythm in cage and their rate of digestion indoor were looked into, and their daily ration was estimated through the method of daily average fullness index. Using the spectrophotometer, the content of chlorophyll a in the stomach was measured, and the feasibility of taking the chlorophyll a as an index of measuring the feeding of fish on phytoplankton was studied. Adopting the national standard method, the effect of the three fishes" excretion on total nitrogen, total phosphorus, CODMn, pH, turbidity and conductivity coefficient was surveyed.

The Seven Star Garden and The Elephant Hill of four star tourist areas in Guilin were chosen to conduct a questionnaire survey. What we want to explore and validate through this study is as follows:⑴How many individual and tourist area factors will influence tourists perception of crowding in tourist areas ?⑵Whether and how perception of crowding will influence the tourist emotions ?⑶Whether perception of crowding has influence on tourist area experience factors ?⑷Whether perception of crowding has influence on evaluations of tourist satisfaction, revisit desire and recommendation desire ? It is found with questionnaire-settled and data statistic analysis that:①"relaxing spirit"and"enjoying beauty"of tourist motivation factors, crowding tolerance and crowding anticipation have remarkable effect on perception of crowding;②"Tourists on the tour road","tourist behavior"and"tourist area space"have remarkable effect on perception of crowding;③The pleasure emotion and arousal emotion of tourists have remarkable effect on perception of crowding;④The perception of crowding has remarkable effect on the sight, entironment, service and establishment of the tourist area in tourist area experience.

In the experiment section, there"re three experiments investigating implicit attitude and dual-attitude model. In the first experiment, the author studies the effects of attitude strengthen on attitude"s automatic activation effect. In the second experiment , the author studies the effect of delay condition on the attitude"s automatic activation effect. Delay condition make experiment approach to mere exposure of attitude object, and two experiment demonstrate attitude"s automatic activation effect is the result of noncognitive processing.

Because of nitrogen, the value of IAA/ABA、GA3/ABA、(IAA+GA3+ZR)/ABA in grain promoted at seed filling stage and at the mature stage.6、The adjustment of nitrogen levels on carbon and nitrogen metabolism.Nitrogen reduced the C/N in leaves and stem. When the nitrogen rate was 50 kg/hm2, the effect on stem was obvious. When the nitrogen rate was 100 kg/hm2, the effect on leaves was obvious. The C/N in roots lower before seed filling stage and the effect was not obvious after seed filling stage.7、Effect of nitrogen levels on yield traitsPlant height, pods per plant and full grain number were increased and bottom-pod height and podded node were decreased by applying nitrogen.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
