可以延缓的

DPU at a concentration of as low as 10^(-7)mol/L retained the chlorophyll of Spirodela half-fronds under long-day conditions. From 10^(-5)~2×10^(-4)mol/L it prompted the synthesis of chlorophlly and the serine: glyoxylate aminotransferase activity, increased dry weight, and retarded the senescence of half-fronds.

在长日照条件下，10^(-7)mol/L的二苯脲对紫萍半叶状体就有保绿的作用，10^(-5)~2×10^(-4)mol/L的二苯脲还可以明显地促进叶绿素的合成和干重的增加，提高丝氨酸：乙醛酸转氨酶的活性，延缓半叶状体的衰老。

It has shown by the studies at home and abroad that Chaga is the ideal companion which has health care, prevention function and can treated many diseases. The healthy groups can use it for fitness beauty、disease prevention and health care; sub-health groups can restore nature health; and disease groups regards its as the best natural therapeutic products without any side effects. The Chaga's own characteristics determines its using value in the health care market, which can be taken as the health products, that is, regulating immunity, anti-virus, anti-cancer, balance blood sugar, balancing blood pressure, improving cardiac function, treating various incurable diseases, removing free radicals, anti-oxidation, anti-aging, and so on.

国内外研究证明桦褐菌是21世纪人类最理想的保健、预防、治疗多种疾病的最好伴侣，健康的群体可以用之健身美容、防病保健，亚健康群体靠其还原健康的本色，疾病群体用其作为最好的天然、无任何副作用的食疗制剂，桦褐菌自身的特点决定了其在健康产品市场的应用价值，可作为调节免疫、抗病毒、抗癌、平衡血糖、平衡血压、改善心功能、治疗各种疑难杂症、清除体内自由基、抗氧化、延缓衰老等健康产品。

Lycopersicon esculentum var.cerasiforme plants were planted in garden pots and 2 000 mg·L-1 SOD were sprayed on them one,two,three times respectively,the ck was sprayed by water,the effects of extrinsic SOD on anti-oxidase activity and the contents of MDA and sugar of the tomatoes were studied.

&SOD水果&是近几年来食品消费领域的一个价格昂贵的新产品[1~5]。根据&自由基启动衰老&的理论[6]，由于SOD在清除氧自由基中的重要作用，使消费者相信富含活性SOD的食品可以清除体内的氧自由基，起到延缓衰老的作用。

The cell structure refining mechanism shows that adding Mg decreases the surface tension of the aluminum alloy melt and hence to increase the bubble stabilization. Adding nuclear forming agent increases the nuclei of heterogeneous nucleation. Adding pre-heating foaming agent postpones its decomposition, hence to increase the uniform of foaming agent dispersion. Stirring within the middle stage of foaming agent rapid decomposition breaks up big bobbles to fine bobbles, hence to reduce mean cell diameter.

孔径细化机理分析表明，Mg的作用在于降低铝熔体的表面张力，提高气泡稳定性；形核剂的作用在于增加气泡非均匀形核的核心；发泡剂氧化预处理可以推迟和延缓发泡剂的分解，提高发泡剂的分散均匀性；搅拌发泡的作用是在发泡剂剧烈分解的中段，通过搅拌搅碎气泡，减小平均孔径。

It was found that the main reason why SBS containing oil was easy to yellow was that there is plenty of polycyclic aromatic hydrocarbon in the extender oil,PAH can easily turned quinones with yellow.Antiyellowing performance of SBS can be only developed in a little extent when antioxidants were added.The anti-yellowing performanc...

研究结果表明，充油SBS产品变黄的主要原因是油品中的稠环芳烃在光氧环境中易转化为黄色的醌，添加抗氧剂对延缓产品变黄的作用不大，通过催化加氢消除填充油中的芳烃或添加适当的光稳定剂可以提高产品的耐黄变性能。

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.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
