According to the results of experiments, we get to know that the diameters of particles of C.I. Vat Blue 4 are about 0.5μm, which meets the requirement of spun-dyed viscose as a dyed-reagent. The choice range of color will be increased when pigmental dye is used as a dyed-reagent for spun-dyed viscose.

通过实验可知，对还原蓝RSN进行颜料化后，其粒径可以达到甚至低于0.5μm的水平，满足粘胶纺液着色加工时对着色剂的粒径要求，可以应用于粘胶的纺液着色纺丝加工，这将扩大纺液着色加工时对色彩的选择范围。

Rb-Sr isochron age of porphyroid fine granite most closely related with molybdenum mineralize is 154Ma,K-Ar isochron age is 152Ma.

研究表明，分布广泛的似斑状中粗粒花岗岩K—Ar年龄为219—188Ma，与钼矿化有密切关系的似斑状细粒花岗岩Rb—Sr等时线年龄为154Ma，K—Ar等时线年龄为152Ma。

At 8 weeks, the liver in the experimental group developed purple, seems wrapping with millets. Pathological sections showed punctiform or lamellar cellular necrosis, inflammatory cell infiltration around liver canaliculus, displaying early symptoms of liver fibrosis. At 12 weeks, the liver looks gray, seems wrapping with many types of millet.

实验组8周时，肝脏呈暗紫色，表面有轻微粟粒样改变，病理切片示：肝细胞点状及点灶状坏死，汇管区炎症细胞浸润，呈早期纤维化症状。12周时，肝脏呈灰褐色，有较明显粟粒样改变。

Experimental results indicate that for the polystyrene particle with a larger size, Umf changes with p-0.3, and for the sand particle with a smaller size, Umf changes with p-0.21. An empirical equation about Umf is proposed based on the experimental data: Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝ It is found that the bed expansion height increases with the increasing of gas velocity, and increases with pressure for fixed value of UUmf, when the pressure exceeds 0.7MPa, the influence of pressure on the bed expansion height is weakened.

研究结果表明，大粒径聚苯乙烯颗粒的Umf与p-0.3成比例，小粒径石英砂的Umf与p-0.21成比例，并根据实验值拟合出压力下最小流化速度公式为： Umf=μdp ρg｛［(34.15)2+0.05916×dp3 ρggμ2］12-34.15｝床层膨胀高度随气速的增大而不断增高，在相同UUmf下床层膨胀高度随压力的增大而增高，在大于0.7MPa时，压力对膨胀高度的影响减弱。

In order to prevent linear PCV2 cyclization, PCR mutagenesis was used to construct the first molecular clone (pSK-2PCV2) by ligating two copies of the complete PCV2 genome with the pBluescript SK vector. In addition, pSK-PCV2 and ds-PCV2 were constructed. PK-15 cells were transfected with above three infectious clones.

本研究应用PCR诱变技术解决了外源片段易于自连的难题，成功将2个PCV2 SD1株全基因组(DQ346683)头尾相接插入到真核生物表达载体pSK的多克隆位点中，构建重组质粒pSK-2PCV2；另外课题组成功构建含单个PCV2全基因组的pSK-PCV2和自身环化质粒ds-PCV2。
