Take DPPH··ethanol solution as the oxidant system to research on the DPPH··scavenging capacity of the liquid fermented vinegar from north fruits like hawthorn, apple, tangerine, beach jujube, kiwi fruit, pear, mulberry, persimmon, medlar, kernel-apricot etc. and grains like corn, sorghum, millet, wheat, buckwheat, Job"s-tears, purple rice etc. it was found that the scavenging effect on DPPH··of the grain vinegar and fruit vinegar after brewing and sterilization was significantly higher than that of their corresponding vinasse, and With the increase of addition, scavenging rate is gradually increased. To most fruit vinegar and grain vinegar, the scavenging effect on DPPH··are stronger than acetate, and acetic acid has some effective but is not functional, consequently it"s other ingredients that really played scavenging effect in the fermentation of vinegar.
本实验采用DPPH··乙醇溶液为氧化体系,研究北方产山楂、苹果、蜜橘、滩枣、猕猴桃、酥梨、桑椹、水柿、枸杞、仁用杏等数十种果品,以及玉米、高粱、小米、小麦、荞麦、薏米、黑米等数十种粮食作物为原料的液态发酵醋对自由基DPPH··的清除能力,结果发现经过酿造杀菌后的成品果醋及粮食醋对DPPH··的清除作用明显高于其相对应的酒醪;并且随着加入量的增加其清除率也逐渐增高,其中大多数果醋及粮食醋对DPPH··的清除作用均强于醋酸,发现醋酸对DPPH··虽然有一定的清除率但是作用不大,因此说明真正对DPPH··起到清除作用的还是发酵醋中的其他成分。

This dissertation was focused on the research about the formation and evolution of NQB from the Late Triassic to the early middle Epoch of Jurassic Period, including integrated analyzing the characteristic of the key stratigraphic surfaces, the time of the key stratigraphy, regional rock straigraphy, biostratigraphy and chronostratigraphy, sedimentary system and depositional facies. On basis of these analysis, a tectonic evolution model have been established for NQB during from the Late Triassic to the early middle Epoch of Jurassic Period.1. After the systematic surface analysis about main stratigraphy units, we found that:(1) the bottom of Xiaochaka formation was comformity with the middle Triassic in the basin, and in the north margin it was deposited and overlapped on the different period stratigraphy before Triassic.(2) The top surface of Xiaochaka formation developed regionally karst and paleo-karst breccia, and was uncomformity with Nadigangri Formation, these things suggest that NQB in Xiaochaka depositing stage was developed from middle Triassic basin, and then an extensive regression occurred, the deposition was over and erosion come into being.(3) The lithologic assemblage, geochemistry, mixed fossils, and stratigraphy overlapping characteristic of Quemocuo Formation in early middle Jurassic indicted that the uncomformity surface was an extension-unconformity.2. Integrated analysis about stratigraphy division and correlation indicted that:(1) the paleontologic assemblage of Xiaochaka formation show its time was Carian -Norian stage of late Triassic. According to it was overlapped by late Triassic Nadigangri Formation, so Xiaochaka formation should be Carian - early Norian stage.(2) the SHRIMP Zircon U-Pb age of Nadigangri formation volcanic rocks wear vary form 216 to 205 Ma, so its time should be Norian, but maybe extended into Rhaetian Stage.(3) The age of its bottom volcanic rocks, the fossil assemblages of its middle and upper members and overlapped by lower Jurassic, indicted the age of Riganpeicuo Formation was Norian - Rhaetian stage. And the same time, the volcanic rocks geochemistry of Nadigangri and Riganpeicuo formation both reflected that they wear formed in rift tectonic settings. The lower lithologic and surface characteristic, fossil assemblages and its upper maybe was conformity with lower Jurassic, all reflected that the age of Tumengela Formation in Tumen area should be Norian - Rhaetian stage.

The effective stimulating sites were indentified by defensive cardiovascular response and other components of defence reaction evoked by 3 s trains of rectangular cathodal pulses (100Hz, 0.5ms pulse duration, 70 -150μA intensity for dPAG and 150-250μA for PF) delivered from a programmed multichannel constant current stimulator. The responses included an increase in blood pressure and heart rate, pupillodilation and an increase in the rate and depth of respiration. Currents of 1Hz, intensity of 100- 150μA for dPAG and 200-250μA for PF were used to observe the effect of the stimulation of them on RVLM neurones. The deep peroneal nerve and superfacial deep peroneal nerve were carefully separated, and put on a pair of stimulating electrode respectively, Both nerves were stimulated with constant rectangular pulses of 1Hz, 0.5ms duration and 300μA current intensity to see their effects on RVLM neurones. The baro-and chemo-receptors were activated by the intravenous injection of phenylephrine or 0.208 M NaH2PO4. The degree of convergent inputs to individual RVLM neurone was studied by the stimulation of the sites mentioned above. It was found that neurones about 61.4%(27/44) and 35.3%(6/17) received convergent inputs from three and four places respectively.
过去的研究主要集中于整体水平,利用电刺激或化学刺激RVLM神经元,观察对血压、心率及交感活动的影响,并对影响心血管交感活动的神经递质进行了广泛探讨,积累了大量资料;在神经元水平,主要研究刺激脑内核团、外周神经、化学感受器及压力感受器等对RVLM神经元放电的影响和某些神经递质影响神经元活动的机制、然而,对RVLM神经元如何整合不同信息、其可能突触机制等研究得较少,本互作拟采用在体细胞内、细胞外记录电活动与微电泳,结合中枢核团及外周神经电刺激等方法,对RVLM神经元在不同状态下的整合作用规律与可能机制进行初步探讨,为进一步了解这一复杂的整合过程提供新的理论依据。

On the other hand, through the discussion on coronal density of flares, we found that the column mass density at the top of chromospheric flare model can not be represented the total mass above the chromosphere and the coronal density can be estimated from presure balance based on semiempirical model. Through estimations, the results show that the total mass above the chromosphere is about the same as the mass between the top of chromosphere and electron source, which so give an evidence that the source of electrons is situated at the top of flare loop.
另一方面,通过对日冕物质密度的讨论发现,半经验模型中色球顶部柱数密度不能用来代表耀斑环在日冕内的总物质,日冕物质密度可用日冕气压与半经验模型中色球顶部压力近似相等来进行估计,进而发现耀斑环在日冕内的总物质与前面估计的色球顶部到非热电子源之间的总物质近似相等,结果趋向于支持非热电子源位于环的顶部。

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.
