Finally, the relationship between the performance of doped a-Si: H and process conditions is discussed, which includes the deposition of n〓-a-Si: H and p〓-a-Si: H, the relationship between dark conductivity, photoconductivity of boron light-doped a-Si: H and process conditions, and the relationship between the stability of LCLV and S-W effect of a-Si: H.

最后讨论了掺杂a-Si：H的性能与工艺条件的关系，包括重掺杂n〓、p〓非晶硅的制备，硼轻掺杂a-Si：H的暗态电导率与工艺条件的关系，硼轻掺杂a-Si：H的光电导与工艺条件的关系，以及液晶光阀的稳定性与a-Si：H的S-W效应。

If A is a symmetric positive definite matrix, then the quadratic form x~ TAx can be written as a sum of squares. Equivalently, A is a sum of rank one matrices VV~T.

若A是对称正定矩阵，则二次型x~ TAx 能写成平方项的和，即A是秩为1的矩阵VV~T的和。

The three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.

结果：(1)从牙本质的应力大小来看，A组中牙本质最大应力值比B组中牙本质最大应力值增大了1倍以上（最大主应力、最小主应力和最大剪切应力A组分别是B组的236.35%、228.83%和218.05%），而B组与C组的牙本质最大应力值相差极小；(2)从牙本质的应力分布位置来看，A组与B组的牙本质最大应力分布位置相差甚远（A组主要集中在牙颈部唇舌侧肩台部的牙本质上，B组主要集中于牙槽嵴顶附近及铸造桩核尾端相对应的唇舌侧的牙本质上），而B组与C组的牙本质最大应力分布几乎在同一位置。

While early studies focused on the potential roles in health and disease of provitamin A carotenoids, such as b-carotene, research over the past decade has provided a framework for our understanding of the functions of non-provitamin A carotenoids such as lycopene, especially in regards to its association with a reduced risk of a number of chronic diseases, including cancer.

人们早期的研究多关注于如β胡萝卜素等维生素A前体类胡萝卜素对于健康和疾病的潜在作用，而近几十年的研究为对于如番茄红素等非维生素A前体类胡萝卜素的功能认知提供了参考，特别是关于它与降低包括癌症在内等慢性病的患病风险的联系。

Results The personal doses range of radiotherapentic operaturs is 0.26-6.54 mSv/a, average 2.27 mSv/a. The personal doses range of radiodiagnosis operators is 0.12-3.24 mSv/a, average is 1.35mSv/a.

结果 放射线治疗工作人员个人剂量范围为0.26～6.54mSv/a，平均为2.27mSv/a；放射诊断工作人员个人剂量范围为0.12～3.24mSv/a，平均为1.35mSv/a。

The measured data were fitted with the modified rectangular hyperbola models of the photosynthetic responses to flag leaf intercellular CO2 concentration A/C(subscript i and air CO2 concentration A/C(subscript a aimed to approach the reasonability of the fitted results obtained from the models.

结果表明：由A/C和A/C修正模型所给的光合能力和CO2补偿点几乎相同，但得到的光呼吸速率和初始羧化效率则完全不等；产生这种差异的原因是利用叶片气体交换测定的数据所计算的胞间CO2浓度并不是植物叶片本身的胞间CO2浓度；A/C修正模型比A/C修正模型更为合理是因为A/C所估算的光呼吸速率接近测量值。

In the fist part, considering the game theoretical aspect of generalized Cohen's forcing C in dependence of ideal / on ω, Generalized a result of Sharp in Combinatorics on Ideals and Axiom A(The Journal of Symbolic Logic,1994), we argue that if J is a regular p*-ideal then C do not satisfy Axiom A.

第一部分通过讨论ω上的理想J的广义Cohen's力迫C的博弈论性质，我们推广了Sharp在论文Combinatorics on Ideals and Axiom A(The Journal of Symbolic Logic，1994)中的一个主要结果——如果U是一个超滤，则其对偶理想J=U~*所作成的广义Cohen's力迫C不满足力迫公理A，我们进一步证明了如果J是一个正则的p~*-ideal则C不满足力迫公理A。

Aureus secretor strain in a media containing vegetarian amino acids or peptides instead of animal peptides, harvesting the Protein A-containing media and purifying the Protein A by applying it to a synthetic resin that lacks animal peptides and filtering the elutant from the resin.

本发明涉及制备没有动物源产物污染的蛋白A的方法，其包括通过在含有植物氨基酸或肽代替动物肽的培养基中发酵金黄色葡萄球菌分泌菌株，收集含有蛋白A的培养基和纯化蛋白A，并且将其施加到没有动物肽的合成树脂上和过滤来自树脂的洗脱液。

Selaginella extract was given for 26 weeks,ALP,TRAP,BGP,TNF-αlevel of drug group A were significantly lower than the model(P.01);E_2,CT level in drug groups increased significantly(P.01),group A and group D were the most obviously.Dosage in group D was only 1/4 of the dosage level in group A.
