值分布

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

Results Of the observed 56 parameters of rats and mice 80.4%indicated that the threshold doses for prenatal HTO exposure ranged from 0.030 Gy to 0.092 Gy,and the other 19.6%showed the threshold doses from 0.093 to 0.300 Gy.

Treatments were as follows: fertilization during leaf-expansion period, fertilization during green-leaf period, and no fertilizer. Results showed that individual leaf area, thousand-leaf weight, and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number, leaf weight per plant, and leaf area index. Fertilization during led-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy.

结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8%和13.7%，比不施肥提高27.6%和24.5%；冠层14~17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。

ND-1 scFv was labeled with 〓Tc by MTD.〓Tc-ND-1 scFv was injected into mice bearing the CCL-187 xenograft for biodistribution study, radioactivity in blood, tumor and normal tissue was determinated at various time periods following injection by a gamma scintillation counter, and the ratios of radioactivity between tumor tissue and normal tissue were evaluated. Radioactively- labled scFv displayed rapid localization in tumors. Accumulation was found in tumors in high concentrations 1 hour after injection, and scfv uptake in tumor was 2.6 times higher than in blood. The T/NT for blood, liver, spleen , hear, lung and kidney were 2.61, 1.85 1.94, 1.75, 0.83 and 0.22 respectively.

将ND-1scFv与同位素〓Tc偶联制备〓Tc-ND-1scFv，注入荷瘤裸鼠体内，观察了偶联物的体内生物学分布，结果显示，〓Tc-ND-1scFv在荷瘤裸鼠体内的生物学分布带有明显的肿瘤积聚趋向，注射1小时后即可选择性地积聚于肿瘤组织，其放射性明显高于大多数正常组织，除肾脏和肺外T/NT值均大于1.2，而完整的ND-1完成同样的积聚则需要20-24小时。

The following main results are obtained: The TiO_2 photocatalyst with small crystallite size, high surface area, narrow and uniform pore size distribution, and microporous frameworks could be prepared out by applying MW radiation in the preparation process. The microwave-induced fluorescence technique verified for the first time that microwave enhanced the formation rate of hydroxyl radical, leading to the increase in the photocatalytic efficiency. Compared with the conventional catalyst, TiO_2 prepared by MW dielectric heating owns a higher UV absorption ability, and its optical absorption edge and photovoltaic response are shifted toward the short wavelength region, resulting in increase of photooxidation efficiency. The photocatalytic conversion and the mineralization ratio of acetaldehyde are increased respectively by 30% and 40% over the TiO2 prepared by MW radiation when compared to the TiO2 prepared by the conventional heating. For the MW-assisted photocatalytic reaction over the MW-prepared TiO2, production of hydroxyl radicals is enhanced by 22.5%, and the photocatalytic conversion is accordingly increased by 20%. Similarlly, applying MW also increased the photocatalytic conversion and the mineralization ratio of acetaldehyde over TiO2/Al2O3 sample.
