Results showed that the CO2 absorb ability in the eight Crop systems net productivity process was 4 032 366ta^(-1); the amount of CO2 outlet in the soil was 3981753ta^(-1), less than the CO2 adsorb ability, so that the whole crop system was a weaker carbon sink process in the atmosphere. The continue planting species such as Rice, sugarcane, cassava, and melon crop or high haulm crops have the characteristics of annually crop net productivity CO2 absorb ability bigger than soil CO2 outlet and this systems had bigger carbon sink function ability; the short haulm crop systems of peanut, soybean, flowers, and vegetable annually crops net productivity CO2 absorb ability less than soil CO2 out let, but also carbon sink source. The CO2 absorb ability of fruits and economic parts above ground bigger than that which growth under ground. Except of the CO2 absorb ability less than the soil CO2 outlet in the peanut during growth in procreate period, the other seven crops CO2 absorb ability were bigger than that soil CO2 outlet during procreate period. Most of crops during growth in procreate period had carbon sink function ability, and only in barren period showed the carbon source function phenomenon.

结果表明：2005年广州市8种农作物系统作物净生产力吸收CO2 4032366ta^(-1)，其土壤CO2排放3981753ta^(-1)，吸收大于排放，对大气CO2而言，整个农作物系统是一个弱的碳汇；水稻、甘蔗、木薯和果用瓜4种连作或高杆作物系统每年作物净生产力吸收CO2量大于土壤CO2的排放量，系统具有较大的碳汇功能，花生、大豆、花卉和蔬菜4种矮杆作物系统每年作物净生产力吸收CO2量小于土壤CO2的排放量，系统起着碳源作用；果实或经济产量生长在地上部分的作物其单位面积吸收CO2能力比果实生长在地下的作物大；除花生在生育期间生物量吸收CO2量少于同期土壤排放以外，其余7种作物在生育期间生物量吸收CO2的量大于同期土壤排放，大多数农作物在生育期间具有碳汇功能，在撂荒期才体现碳源作用。

Using simulations, we found the best geometry of the collimator is the one with a rectangle aperture and all of them are placed in two groups with an orthogonal orientation, which will have good resolution and sensitivity, and also be easy to manufacture. The rectangle aperture gives good imaging accuracy along the short side, and wide viewing along the long side. The orthogonal orientation for collimators will allow us to observe the source and the background simultaneously.

通过模拟发现，综合考虑了对强源成像的分辨率以及对弱源的灵敏度，以及加工的容易程度，论文提出了最优的准直器设计方案是用长方形准直器，并且将所有准直器分成两组，垂直摆放，一方面可以约束两个方向上的成像质量，同时具有较高的成像分辨率和定位精度，并且非常利于定点观测时的源和本底同时观测。

Peripherin-kizami effect of holography: adoption of the photoetching machine computer programming walk-by-bit imaging technology and identifies the surface brightness, along with the change of the perspective that identifies the patterns occur within the rules of a beautiful animation, plus a hierarchical pattern can be a strong level of icing on the cake and more graphics and text content, the user thereby to protect their products from others phishing as well as the purpose of improving the products concerned and show their uniqueness and uniqueness, thus increasing the added value of coplasticizer products and enhancing brand image.

After orthogonal test analysis of three factors, three levels and 27 kinds of compositions,the causes of the putridity of the Rugosa rose fresh cuttings were investigated.

通过三因素三水平 2 7种组合的正交试验和分析，认为插穗腐烂病的发生是由于难生根的离体保加利亚玫瑰嫩枝插穗的抗性弱、空气和土壤的高温高湿条件所造成的；分析还表明土壤因素对保加利亚玫瑰嫩枝扦插腐烂病影响最大，其次是插穗因素和浸穗试剂，并据此提出感病率较低的 4种组合类型。

In the long run, the cumulative effect of inequality on investment is negative.（2） Inequality has moderate effect on education, and the cumulative effect is positive.（3） The effect of inequality on investment overweighs its effect on education, so inequality has a strong indirect effect on growth instantaneously. The effect turns positive and then weakly negative.

研究发现：（1）收入差距在即期对投资有非常强的负面影响，之后影响变为正，再逐渐下降至微弱的负，从长期来看，收入差距对投资的累积影响始终为负；（2）收入差距对教育的影响较弱，其累积影响始终为正；（3）由于投资对于经济增长的作用超过了教育，因此收入差距对于经济增长的间接影响主要来自于投资的渠道。

The dissipation factor tip-up D tan d , the change of capacitance D C / C 0, the maximum discharge q max and the mean discharge magnitude q mean , A compared investigation of the correlations between V min , V av and service time were compared with those between D tan d , D C / C 0, q max, q mean and respectively.

The joint toxicity was evaluated by different methods, including toxicity unit,additive index, similarity parameter and mixtures toxicity index. The results show that the binary joint effects of phenol and toluol mixed with SDS are synergistic, while the binary joint effect of SDS and nitrobenzene is antagonistic. The environment risk of some compounds will be enhanced because of the joint of SDS.

研究结果表明： 4种不同的评价方法对SDS与取代芳烃苯酚、甲苯和硝基苯的联合效应评价结果具有较好的一致性，即SDS与苯酚、甲苯的二元混合体系的毒性表现为不同程度的协同作用，而与硝基苯则表现为弱拮抗作用；对环境存在风险性的阴离子表面活性剂SDS，当与一些有毒有害物质共存时会增加该类物质的环境风险性。

利用梯度投影与罚函数相结合的技巧，将带不等式和等式约束的优化问题化成一个无约束问题，提出了初始点可任意的求解不等式、等式约束优化问题的摄动梯度投影算法；参数δk取不同的数还可以得到一类梯度投影算法，从而得出了在搜索方向和步长不精确条件下的梯度投影法，保证了在实际应用中更容易实现；在较弱条件下，证明了该算法的全局收敛性。

Then we transfected transitorily the recombinant of green fluorescent protein gene and middle molecular weight neurofilament cDNA into wide type N2a (N2a/wt) and N2a/tau40 to observe the effect of tau accumulation on GFP-NFM fusion protein transport in cellular processes in living cells. At last we used an apoptotic inducer, camptothecin (an inhibitor of topoisomerase-1) to treat N2a/wt and N2a/tau40 cell lines, and compared their apoptotic response.

主要结果如下：一、tau蛋白过度表达和聚积对细胞形态的影响：倒置显微镜下观察两种细胞的形态，发现N2a/wt细胞的突起多而长，而N2a/tau40细胞胞体变圆，突起明显缩短；免疫印迹结果显示转染了tau40的细胞内tau的免疫反应约增加14倍，免疫荧光结果显示N2a/tau40细胞胞体内呈现出较强的红色荧光，tau主要分布在核周和突起起始部分的胞质内，而N2a/wt细胞内的荧光很弱。

The smaller the financial turmoil, a weak correlation with the economic mainstay, is not in the field of high-profile, bottom-up approach to select those sub-sectors leading companies as an investment focus of attention, on the one hand, these companies may have been formed by virtue of their own Competitive advantage, other companies in the industry faced difficulties when mergers and acquisitions to expand market share, at the same time these companies have the most potential for innovation.

规模较小的金融风暴，经济主体与弱相关，是在引人注目的，自下而上的办法现场没有选择的分一方面部门领导作为投资重点关注的公司，这些公司可能是由自己的竞争优势而形成的，在该行业的其他公司合并时所面临的困难和收购，以扩大市场份额，同时这些公司最适合创新的潜力。
