Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2)The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.
主要结论如下:1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点,性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点,Grass功能群对水分梯度的响应敏感性较低,Forb居中,Legume表现出较强的敏感性,表明Grass功能群对水分的耐受性比较强,这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状,对物种之间的替代有一定的指示性。

In wetter habitats, forbs were more abundant and accounted for the majority of aboveground biomass, whereas grasses became more important in dryer habitats. Shrubs and sub-shrubs increased with decreasing soil water availability and their relative biomass rapidly increased in degraded steppe and sand dune; perennial grasses had significantly higherδ〓C values than other PFGs; the δ〓C values of perennial grasses and forbs increased with decreasing soil water availability, while those of shrubs/sub-shrubs showed an inverse trend.
在较湿润生境,多年生杂类草更加丰富并构成了群落地上生物量的绝大部分;而在较干旱生境下,多年生禾草在群落中起更重要的作用;随着土壤含水量下降,灌木和半灌木逐渐增多,且在退化草地和沙地中其相对生物量迅速增加;多年生禾草δ〓C值显著高于其它功能群;随着土壤水分可利用性降低,多年生禾草和杂类草的δ〓C值表现出增加的趋势,而灌木/半灌木则表现出相反的趋势。

With the increase of establishment years, most of plant communities on the grasslands showed a "V" type change trend in their quantities, i.e., high-low-high, hut the forbs biomass had a "Λ" type change trend and the sedge biomass increased gradually. Soil nutrients presented a "V" type hut soil hulk density presented a "Λ" type change trend, bile soil pH presented a decreasing trend. Most of soil microbial physiological groups and microbial biomass carbon showed a "V" type change trend, phosphorus-dissolving bacteria showed a "Λ" type change trend, denitrifying bacteria decreased gradually, while cellulose-decomposing bacteria showed an increasing trend.
结果表明:随着人工草地建植年限的增加,植物群落的数量特征多呈高-低-高、杂类草生物量低-高-底、莎草生物量增加的趋势;土壤养分变化为高-低-高、容重为低-高-底、pH呈下降趋势;土壤中多数微生物的数量及微生物生物量碳含量的变化为高-低-高,纤维素分解菌数量逐渐升高,而反硝化菌数量逐年下降,溶磷菌数量呈低-高-低的动态变化。

Sativa meal and both weight gain rate and relative growth rate also increased significantly. The above indexes of fish fed 4% and 12% M. sativa meal were higher than those of fish fed 16% M. sativa meal and were lower for fish fed fresh M. sativa than that of the control group. 2 With increased levels of M. sativa meal in the diets, crude protein content in the muscle of fish fed M. sativa meal increased significantly, while EE and cholesterol were significantly decreased and moisture showed a quadric curve variation. Fish fed fresh M. sativa had no improvement in comparison to the control group. 3 Protease and amylase in foregut, midgut, hindgut and hepatopancreas of C. carpio increased with increased M. sativa meal but the variation was not linear.
试验Ⅰ、Ⅲ组的上述2项指标高于对照组,试验Ⅳ组低于对照组,苜蓿鲜草组低于对照组,但差异均不显著。2和对照组相比,添加苜蓿草粉显著或极显著提高了禾花鲤肌肉中粗蛋白质含量,随着苜蓿草粉添加水平的增加,肌肉中粗脂肪和胆固醇水平显著下降,肌肉中水分含量呈先降后升的二次变化趋势,苜蓿鲜草组的肌肉中粗蛋白质、粗脂肪含量和胆固醇水平无显著变化。3添加苜蓿草粉后对消化道各部位蛋白酶活性及淀粉酶活性有促进作用,均呈先升后降的变化趋势,其中试验Ⅱ组的酶活性最高。

Research on Keeping Quality of Different Flesh Types of Prunus persica L.Niu Liang, Wang Zhiqiang, Liu Shu'e, Song YinhuaAbstract: Effects of post-harvest cold storage and Modified Atmosphere Package on fruit hardness, weight losing and soluble solid content of different peach or nectarine varieties were investigated. The results showed that:(1) There were obviously differences of fruit hardness among varieties of different flesh types. In room temperature, FH of '24-30' and 'Zhongtao No.2' went down slower than 'Zhongyoutao No.5' and 'Zhongyoutao No.10'. In cold storage, '24-30', FH of Zongyoutao No.5' and 'Zhongyoutao No.10' descent quickly after 2 weeks of storage while that of 'Shuguang' and 'Zhongtao No.2' quickly descent just after storage.(2) MA package could effectively slow down the decreasing of FH. There were obvious differences among different varieties while 'Zhongyoutao No.10' was less sensitive than others.(3) Soluble solid content went down after harvest and the procedure was slower in lower temperature. In room, MA package seems accelerate the descendent of SSC.
采用不同肉质类型的桃、油桃果实为材料,对采后低温和自发气调包装等对果实硬度、失重和SSC含量等的变化进行了研究,结果表明:(1)不同类型桃、油桃采后果实硬度变化差异较大,常温下24-30和中桃2号果实硬度下降较慢,而中油桃5号、10号较快,在冷库低温条件下,24-30、中油桃5号和中油桃10号两周后硬度出现迅速下降,而曙光和中桃2号在贮藏后即迅速下降,带皮硬度与去皮硬度之间有一定差异,但变化趋势基本一致;(2)MA包装能有效地延缓采后桃、油桃果实硬度的降低,在常温及低温条件下均是如此,不同肉质类型间差异明显,曙光和中桃2号非常敏感,而中油桃10号则不太敏感,即MA包装对其果实硬度降低的延缓没有其它品种明显;(3)采后桃、油桃果实的SSC含量均有一定的降低,低温下该过程较慢,MA包装在常温下有加剧SSC下降的趋势,低温下则不明显,这可能与常温下采后立即进行MA包装不利于&田间热&及呼吸热的及时散发而加剧呼吸有关。

When the temperature and retention time reach 160 ℃and 80 minutes respectively , most of thesolid grease in the garbage is extracted out to become floatable oil which can be separated and recovered readily. Subsequently , the amount of floatable oil begins to decrease since chemical reactions such as the partial hydrolysis of the oil take place. Additionally , the extraction of solid grease from interior accords with first2order reaction dynamic model.
结果表明,湿热处理初期,垃圾脱水率下降,加热40min 后,脱水率开始上升,且温度越高,上升越快,180 ℃加热100min 达最高;随着温度的升高和加热时间的延长,餐厨垃圾脱油性能呈上升趋势,温度越高,上升趋势越明显;当温度达到160 ℃,加热时间达80min 时,垃圾固相油脂基本浸出完全,继续升温和加热,部分油脂发生水解等化学反应,可浮油量开始降低;垃圾固相脂质浸出符合一级反应动力学。

Specifically, the science-majored college students tender to mastery goal orientation. In the test of mastery goal, the junior students get the highest score; the senior undergraduates get the lowest score. There shows a tendency that mastery goal firstly gets strengthen and then gets weaken gradually along with the grade elevation in the college students. In avoid performance goals, the junior students get the lowest score, the senior undergraduates get the highest score. There shows a tendency that avoid performance goals firstly get weaken and then get strengthen gradually along with the grade elevation.

Results showed that the overland flow pattern has close relationship with the grass cover and water inflow rate, it changed from the laminar and tranquil flow to the transition flow and tranquil flow for the grass-covered sloping segment with increasing water inflow rate, but it was almost transition flow and tranquil or rapid flow for the sloping segment without grass cover.
结果表明,坡面流流态与放水流量和草被覆盖关系密切,随流量的增大草被覆盖断面坡面流流态由层流-缓流转变为过渡流-缓流,而无草覆盖断面的流态几乎都处于过渡流-缓流或急流状态;沟坡径流大都属于过渡流-急流状态,试验过程中,草被覆盖断面的径流雷诺数和弗汝德数变化很小,无草被覆盖断面径流的雷诺数呈逐渐增加趋势,而弗汝德数呈逐渐减小的变化趋势。
