乌桕

Results The results showed that the material with the antibacterial activity in sapium root bark primarily was in the part of large polarity, but there was antibacterial activity in the material of the methanol elution with larger polarity; and the inhibitory components of the soluble material of ethyl acetate was complex and the different parts had the variable inhibition to different bacteria and in general these materials had a certain inhibition to Staphylococcus aureus and Escherichia coli.

结果］乌桕根抑菌活性物质主要存在极性较大的部分，但极性很大的甲醇洗脱部分也没有抑菌活性；乙酸乙酯可溶部抑菌成分较复杂，不同部分时不同细菌的抑制作用不同，总体来说对金黄色葡萄球菌和大肠杆菌有一定的抑制作用。

Manshan of Sapium, Maple, like drinking wine harvest in autumn, drunk the whole Gang Luan red, colorful, magnificent, so that visitors to the passion burning, high-spirited Endeavor.

漫山的乌桕、枫树，象喝了秋的丰收美酒，醉红了整个冈峦，色彩斑斓，富丽堂皇，使游人激情燃烧，昂扬奋进。

In order to better understand the determinants of tree height limit,32 tall tree species such as Parashorea chinensis,Sapium baccatum,Garcinia cowa,Eucalyptus citriodora,E.grandis×E.urophylla,Albizia falcataria,Populus tomentosa,Platanus hispanica,Ginkgo biloba,Pinus tabulaeformis,Ulmus pumia,Salix gordeivii,and Elaeagnus angustifolia from typical environments such as Xishuangbanna rainforest,Guangzhou subtropical area,Zhengzhou,Beijing,Helanshan mountain and Maowusu sandland in China were studied.

为了更好地了解树高极限的限制因素，本文对全国典型水分分布区域西双版纳、广州、郑州、北京、贺兰山和毛乌素沙地等地区生长的望天树、浆果乌桕、小叶藤黄、柠檬桉、巨尾桉、南洋楹、毛白杨、悬铃木、银杏、油松、榆树、沙枣、小黄柳等32种较高的木本植物进行了研究。

It showed that, compared with other catalysts, SO(superscript 2- subscript 4)/TiO2-ZrO2 was more active to bring about more than 95% conversion rate of stillingia oil under the transesterification conditions of 150℃, molar ratio of methanol to oil 12:1, catalyst amount 5% and reaction time 6h.

结果表明，催化剂SO(上标 2-下标 4)/TiO2-ZrO2表现出了较高的催化活性，SO(上标 2-下标 4)/TiO2-ZrO2催化的最佳酯交换反应条件为：反应温度150℃，醇油摩尔比12：1，催化剂用量5%，反应时间6h，此时乌桕籽油的醋化率超过95%，且催化剂重复和再生使用效果良好。

Solid acid catalysts such as S2O(superscript 2- subscript 8)/TiO2, S2O(superscript 2- subscript 8)/TiO2-ZrO2, SO(superscript 2- subscript 4)/TiO2-ZrO2, SO(superscript 2- subscript 4)/A12O3-ZrO2 were prepared and their catalyst activities for biodiesel production from stillingia oil were evaluated with the same condition.

通过对S2O(上标 2-下标 8)/TiO2、S2O(上标 2-下标 8)/TiO2-ZrO2、SO(上标 2-下标 4)/TiO2-ZrO2、SO(上标 2-下标 4)/A12O3-ZrO2 4种固体酸催化剂的制备，并在同一条件下比较了它们在乌桕籽油制备生物柴油反应中的催化活性。

In this paper the preparation of biodiesel from Stillingia oil by transesterification is investigated using KF/γ-Al2O3 as solid nanocatalyst.

以γ-Al2O3为载体负载KF，制备纳米KF/γ-Al2O3酯交换催化剂，用于催化乌桕籽油制备生物柴油，研究了不同制备条件下纳米催化剂KF/γ-Al2O3的催化性能。

With the tension of fossil resources, energy diversification and the search for renewable sources of clean energy has become the development direction Chinese tallow oil and processed through a series after extraction of bio-diesel will create huge reserves of renewable energy.

随着石化能源的紧张，能源的多元化和寻求可再生清洁能源已成为当今发展方向，而乌桕籽油经一系列加工处理后可提炼为生物柴油，能形成巨大的可再生能源储备。

The quality values including melting point, iodine value (36.46g/100g, saponification value (197.10mg/g), etc were almost the same as that of CB iodine value (37.05g/100g), saponification value (195.30mg/g).

乌桕类可可脂的特征值(碘价36.46g/100g，皂化价197.10mg/g等)均与天然可可脂(碘价37.05g/100g，皂化价195.30mg/g)的相似。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
