It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.

本实验以菊花的茎尖为外植体，研究了不同灭菌方法，光照强度，全光照、半光照和弱光处理以及不同6-BA和NAA浓度及配比对于试管苗增殖的影响，并研究了珍珠岩、蛭石和河砂等琼脂替代物对于菊花生根的影响，结果表明：在初代培养物建立的过程中采用0.1％升汞进行表面灭菌的效果好于饱和漂白粉的灭菌效果；在全光照条件下外植体的增殖倍数最高；在试管苗增殖培养的过程中，以MS为基本培养基，并在培养基中添加0.2～5mg·L~(-1)6-BA和0.05～2mg·L~(-1)NAA，其中0.2mg·L~(-1)6-BA和0.05mg·L~(-1)NAA最适于外植体的分化和增殖，其分化率为100％，增殖倍数为12。

Finally, aggregation-decomposition-coordination interactive approach is given to solve the multistage linear programming.

在消费经济活动研究方面，首先根据一般效用理论和模糊数学思想提出了能够较好地刻画消费者主观价值概念和消费品偏好的FU消费效用函数。

Although Nahum hopes that earlier intervention brought about by earlier screening will lead to better outcomes for mother and baby, additional confirmatory studies are needed:"We don't know how earlier diagnosis of gestational diabetes will impact maternal-fetal outcomes because we didn't examine that in this study, but that is certainly something to focus on in future research."

尽管Dr。 Nahum希望，除了必要的确诊性研究外，藉由早期筛检进行早期介入治疗，将可使得母亲和孩子的结果更好。我们不知道对妊娠糖尿病的早期诊断会如何影响母亲与婴儿的结果，因为在这项研究中并未加以分析，但肯定的是这将是未来研究所关注的地方。

It seemed to be a very narrow field of study.

这好象是一个非常狭窄的研究范围。

Wavelet multi-scale analysis is applied to the research on lunar gravity field and the explanation of lunar inner structure. In this paper, the nearside of the Moon with higher quality data is chosen as the test area, and free air gravity data from "Clementine" mission are used as original data to decompose gravity of some specific mare basins. With the results of numerical test, we also explain the hierarchical structure of the Moon, analyze the thickness of mare fillings and the Moho topography under mare basins, and verify the results by comparisons.

本文将小波多尺度分析引入月球重力场的研究，选取测量数据质量较好的月球近区作为实验区域，以"Clementine"探测器获得的自由空气重力异常作为原始数据对主要月海盆地进行了局部的重力异常分解，解释了月球内部基本分层结构，并利用主要月海盆地的实验结果分析了月海下部质量异常以及莫霍面的起伏形态，与已有研究成果进行比较证明了方法的适用性及结果的合理性。
