富杆拦石集合体和富黄长石包体的稀土模式大多数为平坦型，富尖晶石包体NQ-32有Ⅱ型的稀土模式，这些特征进一步证实同类球粒陨石的难熔包体特征，尤其是它们的类别是相似的。

In Late Jurassic period (159-135Ma), when the orientation of maximum principal compressive stress was NW direction, the Wuzhangshan granite intruded to upward, accompanied the formation of NW trending Sanrenchang and Huangshuian breccia pipe belts; In the Early Cretaceous period (135-120Ma), when the orientation of maximum principal compressive stress was NNW trending, the second stage of Huashan granite intruded to upward, accompanied the formation of NW trending Qiyugou breccia pipe belts; In 120-105 Ma, when the orientation of maximum principal compressive stress changed to NE direction, the gold-bearing quartz veins and gold orebodies in breccia pipes were formed along the NE trending fractures; In the Middle Cretaceous period (105-85 Ma), when the orientation of maximum principal compressive stress was NEE, the NEE trending Leimengou granite porphyry intruded to upward, accompanied the formation of NEE trending Leimengou breccia pipe belts.

在晚侏罗世(159～135Ma)，构造应力场最大压应力方向为NW向，形成了NW走向的五丈山岩体以及NW向展布三人场、黄水庵两个角砾岩带；在白垩纪早期(135～120Ma)，最大压应力为NNW向，形成了花山岩体第二期上侵，并伴有NW向的祁雨沟角砾岩带；其后(120～100Ma)，构造应力场最大压应力方向变为NE向，形成了NE向含金石英脉及角砾岩体中金矿体；最后(100～80Ma)，形成了雷门沟花岗斑岩以及NEE向展布的雷门沟-杨河沟角砾岩带(区域构造应力场的最大主压应力方向为NEE向)。

The dynamic changes of physiological and biochemical indexes of healthy spikes and inoculation ones of the resistant mutants indicated that PAL activity and content and changing tendency of total phenolate and flavoniods and MDA in the healthy spikes of the mutants were similar to that of their susceptible donors, whereas, for the inoculated spikes, content and changing range of these indexes existed significant difference between two kinds of strains, changing from high-resistant variety (Sumai3 ) to their susceptible donors.

以典型抗扩展品种和突变体供体亲本为抗、感对照，对抗赤霉突变体的健康穗及接种穗的生理生化特性研究结果显示，在健康穗中，抗性突变体的PAL活性、总酚、类黄酮及MDA含量及变化趋势与其感病亲本相一致，但在病原菌侵染后，这些生理生化物质的含量与变化程度与其亲本有了明显的差异，其变化范围介于典型高抗品种和感病亲本之间，变化趋势与亲本或抗性品种一致。

By using the laser-lift-off technique followed by plasma etching process to roughen the surface, the VLEDs with n-GaN surface roughening has been fabricated.

另一部份，则是在垂直式氮化镓发光二极体的表面制造粗化的效果，以来增进光从发光二极体中萃取出的效率，利用乾式蚀刻将表面制造出粗化的效果，再利用标准的黄光微影制成技术，因此成功的制造出n型表面粗化的垂直式氮化镓发光二极体，至於出光强度的增强量会随者表面粗化情况的不同有著30%？

It was known that ORF of SeMNPV egt was 1572bp long and encodes 523 amino acids through DNAstar software analysis. TATA boxes lies at 48~53 and 68~72bp of the 5'-nonencoding region upstream of a translational start site. Comparing with seven kinds of nuclear polyhedrosis virus and one kind of granulosis virus, it indicated that the SeMNPV egt gene is the highest match the Agrotis setegum nuclear polyhedrosis virus.It has 75% nucleotides and 79% amino acid identity.

采用DNAstar软件分析，与7种核多角体病毒及1种颗粒体病毒egt基因的同源性比较显示，SeMNPV egt基因与核多角体病毒egt序列同源性较高，其中与黄地老虎核型多角体病毒同源性最高，核苷酸和氨基酸序列同源性分别为75%和79%。

Polyhedrin and virion, which were isolated and purified from Agrotis setegum nuclear polyhedrosis virus, are administered to 3-instar Heliothis armigera larvae with Heliothis armigera nuclear polyhedrosis virus. Both polyhedrin and virion could increase mortality of H. armigera larvae, shorten half mortality time and decrease half mortality concentration.

对黄地老虎核型多角体病毒的多角体蛋白和病毒粒子组分进行分离纯化，分别与棉铃虫核型多角体病毒混合感染三龄棉铃虫幼虫，发现此二种组分均能够提高棉铃虫幼虫的死亡率，缩短半致死时间，降低半致死浓度。

Nutrient cells were obtained from these pigment mutants by enzymatic method and conchocelis were got by parthenogenesis. When the conchocelis were mature and conchospores were released, they were cultured singly and picked up as F1 gametophytic thallus.

通过酶法分离突变体的营养细胞，单性生殖获得丝状体；分别使丝状体成熟并放散壳孢子，然后单株培养和筛选获得褐黄、翠绿和褐绿色子代叶状体。

Purified GO had a molecular weight between 145, 000 and 162, 300, as determined by Sephadex G-200 filtration and SDS-PAGE of the enzyme as cross-linked with glutaraldehyde. This result showed that the holoenzyme was a tetramer, and no change occurred in molecular weight of the enzyme during the s〓orage. The active form of GO from brassica leaves showed a constant molecular weight during purification, so did that from O. sativa leaves during greening of etiolated seedlings, maybe acting as a stable tetramer.

用Sephadex G-200胶过滤和戊二醛交联后的SDS-PAGE法测得纯化的菜心叶片GO的分子量在145，000-162，300间，为四聚体；并且在放置过程中其分子量和聚合态均保持不变，为稳定的四聚体；进一步研究表明菜心叶片GO在纯化过程中和水稻叶片GO在黄化苗的转绿过程中，两种GO活性状态的分子量和聚合态也没有发生变化，均呈四聚体。
