作为全球重要的碳库,湿地在缓解气候变化方面发挥了重要作用。然而在全球变暖背景下,湿地的碳排放(尤其是甲烷(CH_(4))排放)存在高度变异性和不确定性,极大地削弱了湿地碳库功能的发挥。为了探究不同水深梯度下东北盐碱湿地碳排放通量的特征,本研究以莫莫格湿地为主要研究区,选取5种代表性植被(芦苇(Phragmites australis)、扁秆藨草(bolboschoenus planiculmis)、三江藨草(Schoenoplectus nipponicus)、香蒲(Typha orientalis ***)和碱蓬(Suaeda glauca)),布设Marsh Organ中型实验生态系统模拟不同水深生境,揭示CH_(4)和二氧化碳(CO_(2))排放通量变化及其环境影响因子。结果表明,莫莫格湿地-10~50 cm水深范围内5种代表性植被生长季CH_(4)排放通量范围为0.07~86.74 mg/(m^(2)·h),平均值为8.89 mg/(m^(2)·h),其主要环境影响因素为水深、气温和表层10 cm土壤含水量;在研究水深范围内,代表性植被生长季CO_(2)排放通量范围为10.59~1891.08 mg/(m^(2)·h),平均值为450.12 mg/(m^(2)·h),其主要环境影响因素为水深、气温和表层10 cm土壤含水量。不同植被对碳排放的贡献量有所差异,具体来说,芦苇和香蒲的CH_(4)排放通量最高,而藨草的CO_(2)排放通量最高。碳排放随水深变化呈现分段规律,CH_(4)排放随水深变化呈现先增加后减少的趋势,而CO_(2)则呈现相反规律,随水深变化先减小后增加,其水深临界阈值均出现在22 cm处。在不同水深范围内,CO_(2)排放对于水深的敏感性均大于CH_(4),且当水深大于22 cm时,CH_(4)和CO_(2)均呈现出更高的水深敏感性。碳排放在不同水深范围对温度的敏感程度不同,当水深小于22 cm时,CH_(4)和CO_(2)均呈现出更高的温度敏感性,然而当水深大于22 cm时,二者对温度均不敏感。结果表明升温背景下,东北典型盐碱湿地水陆过渡区关键生态系统在不同水深范围内呈现出不对称的响应模式,频繁的水位波动会极大地改变湿地碳排放格局,从而影响到湿地碳功能的稳定发挥。

Frontiers of Information Technology & Electronic Engineering 2016年第9期17卷 946-953页

作者： jian wu Ting-ting ZHOU bo YUAN Li-qiang WANG State Key Laboratory of Modern Optical Instrumentation CNERC for Optical Instrument Zhejiang University

In this study, a displacement measurement method based on digital moiré fringe is described and experimentally demonstrated. The method is formed by only one grating with a constant pitch. First, the magnified grating image is received by an imaging array and is sent to a computer. Then, the digital moiré fringes are generated by overlaying the grating image with its mirrored one. Finally, a specifically designed algorithm is used to obtain the fringes' phase difference before and after movement and calculate the displacement. This method has the effects of amplifying displacement and averaging the grating lines error, the same as the traditional moiré technique using two pieces of gratings. At the same time, the proposed system is much easier to assemble and the measurement resolution can be set more flexibly. One displacement measuring system based on this method was built up. Experiment results show that its measurement errors are less than 0.3 μm and less than 0.12 μm at the resolutions of 0.1 μm and 0.03 μm, respectively.

目的:探索一种基于CLARITY技术的快速肝组织透明化手段,为该技术在肝脏上的应用提供研究基础。方法:水凝胶灌注大鼠,取出肝脏待水凝胶凝固后切为1mm薄片。切片随机分为两组,对照组采用常规被动脂质清除法处理,实验组置于特制电泳装置中,在外加电场条件下洗涤脂质,通过提高电泳温度并量化组织透明度,探索最优肝透明化条件。结果:实验组在12V电压下37℃电泳48h时肝切片相对透明度达到最高并保持至96h,随后相对透明度开始下降,而在48h电泳清除脂质后提高温度继续电泳48h,肝组织切片相对透明度可进一步提高且对照组脂质清除速率明显低于实验组。结论:在12V电压下肝组织切片37℃电泳48h再辅以52℃电泳48h可以实现较快速的脂质清除。

锅炉冷凝式换热器能深度回收锅炉尾部烟气的水分和热量,在燃气锅炉以及加装了湿法脱硫塔的电站锅炉中得到了一定的应用。对数平均温压法适用于传统非冷凝式换热器的热力计算,但不适用于锅炉冷凝式换热器的热力计算。在目前尚不存在通用性强的锅炉冷凝式换热器热力计算方法的情况下,提出了一种适用于锅炉冷凝式换热器的热力计算方法。采用该方法可分别求出换热器的显热换热量、潜热换热量和冷凝水流量,预测换热器内工质温度、水蒸气体积分数等参数的分布,并判断水蒸气开始发生冷凝的位置。采用文献中的实验数据对该热力计算方法的正确性进行了验证,结果表明烟温和冷凝水流量的计算值和实验值的变化趋势一致,且二者最大偏差在20%以内。该热力计算方法可为锅炉冷凝式换热器的设计和优化提供参考。

Dear Editor,This letter proposes a deep synchronization control(DSC) method to synchronize grid-forming converters with power grids. The method involves constructing a novel controller for grid-forming converters based on the stable deep dynamics model. To enhance the performance of the controller, the dynamics model is optimized within the deep reinforcement learning(DRL) framework. Simulation results verify that the proposed method can reduce frequency deviation and improve active power responses.

Objective： To investigate the possible correlation between osteoglycin expression and gelatinases activity of tumor cells. Methods： Eukaryotic expression plasmid and antisense expression plasmid of osteoglycin were constructed, and transfected into mouse hepatocarcinoma Hca-F cells and Hca-P cells, respectively. RT-PCR and Western blot were employed to analyze osteoglycin expression in tumor cells. Zymographic analysis was used to observe the possible correlation between osteoglycin expression and gelatinases activity of tumor cells cultured under different conditions. Results： High expression of osteoglycin after transfection of osteoglycin gene attenuated secretion of gelatinases in Hca-F cells cultured with extract of lymph node （P〈0.05）. However, transfection of osteoglycin gene into Hca-F cells failed to influence gelatinases activity of tumor cells cultured with extracts of liver and spleen or in DMEM medium. Effective suppression of osteoglycin expression in Hca-P cells by osteoglycin shRNA resulted in enhanced activity of gelatinases in Hca-P cells cultured with extract of lymph node （P〈0.05）. However, inhibition of osteoglycin expression in Hca-P cells failed to influence gelatinases activity of tumor cells cultured with extracts of liver and spleen or in DMEM medium. Conclusion： Osteoglycin expression influences gelatinases activity of murine hepatocarcinoma cells cultured with extract of lymph node. Regulation of gelatinases activity might be one of the mechanisms by which osteoglycin contribute to lymphatic metastasis suppression.

Precipitation is a potential factor that significantly affects plant nutrient pools by influencing biomass sizes and nutrient concentrations. However, few studies have explicitly dissected carbon(C), nitrogen(N) and phosphorus(P) pools between above- and belowground biomass at the community level along a precipitation gradient. We conducted a transect(approx. 1300 km long) study of Stipa purpurea community in alpine steppe on the Tibet Plateau of China to test the variation of N pool of aboveground biomass/N pool of belowground biomass(AB/BB N) and P pool of aboveground biomass/P pool of belowground biomass(AB/BB P) along a precipitation gradient. The proportion of aboveground biomass decreased significantly from mesic to drier sites. Along the belt transect, the plant N concentration was relatively stable; thus, AB/BB N increased with moisture due to the major influences by above- and belowground biomass allocation. However, P concentration of aboveground biomass decreased significantly with increasing precipitation and AB/BB P did not vary with aridity because of the offset effect of the P concentration and biomass allocation. Precipitation gradients do decouple the N and P pool of a S. purpurea community along a precipitation gradient in alpine steppe. The decreasing of N:P in aboveground biomass in drier regions may indicate much stronger N limitation in more arid area.

First principles plane wave pseudopotential method was executed to calculate the mechanical properties with respect to the uranium-0.95 mass fraction of titanium （U-0.95 mass fraction of Ti） alloy for quenching and aging, including the elastic modulus, the value of shear modulus to bulk modulus （G/B） and the ideal tensile strength. The further research has also been done about the crack mechanism through Griffith rupture energy. These results show that the elastic moduli are 195.1 GPa for quenching orthorhombic ~ phase and 201.8 GPa for aging formed Guinier-Preston （G.P） zones, while G/B values are 0.67 and 0.56, respectively. With the phase change of uranium-titanium （U-Ti） alloy via the quenching treatment, the ideal tensile strength is diverse and distinct with dif- ferent crystal orientations of the anisotropic ~ phase. Comparison of quenching and short time aging treatment, both of the strength and toughness trend to improve slightly. Further analysis about electronic density of states （DOS） in the electronic scale indicates that the strength increases continuously while toughness decreases with the aging proceeding. The equilibrium structure appears in overaging process, as a result of decomposition of metastable quenching 7 phase. Thereby the strength and toughness trend to decrease slightly. Finally, the ideal fracture energies of G.P zones and overaging structure are obtained within the framework of Griffith fracture theory, which are 4.67 J/m2 and 3.83 J/m2, respectively. These results theoretically demonstrate strengthening effect of quenching and aging heat treatment on U-Ti alloy.

A quantum mechanical calculation was performed to study the Translation Vibration( T V ) energy transfer of a colinear OH+O/OD+O system, for which Delves coordinates and R matrix propagatation methods were applied to a Mulius Blint potential energy surface. The calculated result of the T V energy transfer probability shows strong oscillation phenomena and the collision delay time of the title system was in the 10 -15 -10 -12 s time scale. The kinetic isotope effect was discussed in this work too.
