Calculations indicate that Ni-Ni interaction in Ni81B19 alloy is stronger than metallic bond in pure Ni. However, the Ni-Ni interaction in pure Ni is stronger than that in Ni80P20 alloy. Direct B-B contact in Ni81B19 alloys appears in our simulation, however no direct P-P contact in Ni80P20 alloys is found.

其次，在Ni的d电子和B的p电子之间存在着强烈的相互作用，形成Ni原子和B原子间的强共价作用。B和P的加入后使催化反应中的活性位Ni的活性d电子数增加，在合金中起修饰作用。

For fixed generalized reflection matrix P, i.e., P^T=P, P^2=I, then matrix X is said to be generalized bisymmetric, if $X=PXP$ and $X=X^T$.

对于某个广义反射阵P，满足P^T=P， P^2=I，那么称矩阵X是广义双对称的，如果满足X=PXP及X=X^T。

This method can be used to detect 16 pesticides in 30 minutes, including organophosphorus (parathion-methyl, phorate, isofenphos-methyl, malathion, chlorpyrifos, fenthion), organochlorine (dichlororos, heptachlor, chlorothalonil,α-hexachlorocyclohexane,γ-hexachlorocyclohexane,δ-hexachlorocyclohexane, p, p'-DDE, p, p'-DDD), pyrethroids and triadimefon in vegetables.

采用选择离子－气相色谱－质谱联用方式，依据保留时间和特征离子丰度比，可以在30 min之内检测有机磷（甲基对硫磷、甲拌磷、甲基异柳磷、马拉硫磷、毒死蜱、倍硫磷）、有机氯（敌敌畏、七氯、百菌清、α-六六六、γ-六六六、δ-六六六、p， p'-DDE、p， p'-DDD）、除虫菊酯、三唑酮等16种农药。

Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively. Butyl acrylate and 2-ethylhexy! acrylate were used as comonomers of ACR core, styrene and methyl methacrylate were employed as comonomers of ACR shell, and 1,4-butanediol diacrylate was used as cross-linking agent.

采用丙烯酸丁酯和丙烯酸2-乙基己酯(2-EHA)为核层单体、苯乙烯和甲基丙烯酸甲酯为壳层单体、1，4-丁二醇二丙烯酸酯为交联剂，通过多步种子乳液聚合方法合成了P、P／P两种具有窄粒径分布的共聚丙烯酸酯胶乳。

P'. "Patch" in isolation tested medium pressure P under the deformation, compression internal working fluid filling the formation of a pressure equivalent to the P P '.

隔离膜片在被测介质压力P的作用下产生变形，压缩内部充填的工作液形成一个相当于P的压力

This kind of gratings can be kept in the material for a long time. A mode of molecular reorientation was used to explain the formation mechanism of these gratings and it is well consistent with our experimental results. 3. Three kinds of azobenzene polymers P , P (MMA-co-GY7) and P (MMA-co-GO13) were synthesized by radical polymerization. High-density optical storage and the three-dimension (3D) microstructures in the azobenzene polymer films were presented. Twenty gratings have been stored on the same spot in our material. It is twice as many as the best recording that has been reported. It is the first time, a rectangular microstructure and a complicated double layers nesting six-pointed star microstructure are inscribed in it by using a simple two-wave couple setup.

采用共聚反应设计合成了单偶氮苯聚合物P、双偶氮苯聚合物P（MMA-co-GY7）和P（MMA-co-GO13）三种聚合物，研究了偶氮苯聚合物薄膜中的高密度光学存储和3维微结构，成功的将20套光栅储存在样品中同一个点上，是已有报道的两倍；并首次用简单的2波混频光路在该材料中刻写出长方格子和六角星型的微结构，在制作多重不同周期不同角度的高密度光栅结构实验过程中，发现不同周期光栅的刻写顺序对整个微结构形成的最终结果具有决定性的影响，并用相衬显微镜观察了这些微结构图像。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
