In the first part of the second chapter,we obtain a equivalent condition of the convolution closure of the extended long-tailed distributions,generalize and improve the corresponding results of Pakes(2004),and then receive a kind of equivalent conditions of convolution-equivalence distributions.In the last part of the second chapter,we prove these results.

本文第二章的前一部分得到了有关广义长尾分布的卷积封闭性的等价条件，推广和改进了Pakes(2004)的一个相应结果，进而得到一类卷积等价分布的等价条件；第二章的后一部分证明了这些结果。

The apparent reduction in income per capita is a mirages caused by defining the migrants as part of first one nation and then another.

那种表面上的人均收入的降低，乃是由于把移民先是规定为这一国家的一部分，然后又规定为另一国家的一部分而造成的一种假象。

But its bigger intervention was to expand a safety net which allows family farmers to sell $800 worth of food to the government each year; the government uses part of the food for reserves to help stabilise prices and another portion for school meals which are part of the country's much-admired conditional-cash transfer scheme, Bolsa Familia.

然而这还不是最重要的，其更有力的措施是建立了安全保障网，保证每年每户农民家庭可以向政府出售价值800美元的粮食。政府将这些粮食中的一部分用来储藏以稳定粮价，另一部分则分给学校的食堂，这是该国备受推崇的有条件的现金转移计划中的一部分，家庭补助金。

But the shift of TEF among regions will result in ecological footprint transfer and exchange between regions, and some of ecological footprint contained in energy consume and shopping product by tourist is imported from other regions, so some of the ecological footprint of Lanzhou City is transferred to other region.

但是，旅游者的跨区域流动引起旅游生态足迹的区际转移与交换，且兰州市游客的能源消费以及购物商品中，有一部分是从区外&进口&，故兰州市游客的旅游生态足迹中有一部分转移至区外。

objective the aim of this study is to investigate the expression and the distribution of the nerve growth factor during the period of neural tube development of human embryo.method early development of neural tube was studied in human embryos about 35 gestational days by using immunocytochemical abc technique.result there were ngf immuno-positive substances in the cytoplasm and nuclei of neuroepithelial cells in the ventricular zones of neural tube.in the intermediate zone of neural tube,ngf immunoreactivity was detected in the nuclei of some neurons,or the processes of other neurons which contained no ngf-immunoreactive substances in their nuclei;the expression pattern of ngf in the marginal zone of neural tube was similar to that of the intermediate zone.the density of ngf-immunorecative particles was higher on the rostrum side of neural tube than on the caudal side.the ngf immuno-positive cells were also observed among the somites of embryo under the neural tube.conclusion these results suggest that ngf was an important signal molecule to induce neural tube differentiation,and that ngf may play a significant role in regulation of the biological function of neurons in developing neural tube.

目的 研究捷安肽素的抗真菌作用机理。方法采用形态学方法和同位素标记法。显微形态观察经捷安肽素处理后的供试真菌的形态学变化。进一步采用14c同位素标记的特异底物&尿苷二磷酸-（14c）-葡萄糖&示踪，研究捷安肽素对真菌(1，3)-β-d-葡聚糖合成酶活性反应的影响。结果研究神经生长因子在早期人胚神经管发育过程中的定位表达。方法采用免疫细胞化学 abc法染色，研究35天人胚的发育情况。结果在人胚神经管的室管带中，神经元的细胞质和细胞核ngf免疫反应阳性；在中间带，一部分神经元的细胞核ngf免疫反应阳性，另外一部分神经元的细胞核ngf免疫反应阴性，而其突起ngf免疫反应阳性；在边缘带ngf的表达与中间带相似。在神经管的头侧ngf阳性反应较强，神经管的尾侧ngf阳性反应较弱。结论 ngf在人胚神经管免疫反应阳性，表明ngf可能是诱导神经管分化发育的重要信号分子，提示ngf可能在人胚神经管的发育中具有十分重要的作用。神经生长因子；人胚；神经管；发育
