IR结果发现所有样品在2850.27cm〓和2917.77cm〓处均有吸收峰，这是由于B〓O中的B〓二十面体位于菱面体单胞内，对称性降低，发生简并分裂所致。

Based on the genetic distance by SSR data, the cluster analysis with unweight pair-group method using arithemetic averages produced two major clusters that closely corresponded with the genome composition of the varieties (A genome, and B genome and their hybrids between A genome and B genome).

应用非加权类平均聚类方法，在相似系数0.61处将24个品种分为两大类群，类群Ⅰ是以A基因组为主的品种群，类群Ⅱ是以B基因组和A基因组与B基因组杂交的品种群。

ResultsCompared with group A and group C, significant increase in the levels of IL 8 and MDA and decrease in the activities of SOD and GSH Px were noted in group B （F=5.86-18.41,q＝3.15-7.17, P.01）; compared with group A, the activity of SOD and GSH Px was not changed markedly, the levels of IL 8 and MDA rised slightly but with no statistically significant. Mitochondria became vacuolated and deformed in group B, slightly swollen in group C.

结果 与A组、C组相比较，B组SOD、GSH Px的活性显著下降，MDA含量、IL 8浓度显著上升(F=5.86～18.41，q＝3.15～7.17，P.01)；与A组比较，C组SOD、GSH Px活性无明显变化，MDA含量及IL 8浓度轻微上升，但无统计学差异。B组肺组织线粒体破坏，呈空泡样变，C组仅见线粒体轻微肿胀。

All illustrate that NF-κB ASODN is effect to the rat endometriosis model, further verificate there is intimate relation between NF-κB and endometriosis.

说明用NF-κB反义寡核苷酸抑制治疗内异症模型有效，进一步证实NF-κB与内异症的发病机制有密切关系。

For example, A..., however, B.... Thus, it is likely much more difficult for B to do....

例如，A。。。，然而，B。。。。因此，对于 B 来说，可能更难。。。。。。

Comparing with the severely conglomerated, larger particles of B〓C sample obtained from metallic sodium co-reduction of CCl〓 and BBr〓 at 400℃ without using solvent, the solvothermal product with well dispersed, uniform nanoparticles indicates that solvothermal synthesis is a better, practical way to nanocrystalline B〓C.

作为对比，在不使用有机溶剂的条件下，通过金属钠共还原CCl〓和BBr〓于400℃下也制备出B〓C微粉，但产物颗粒较大，团聚严重。表明溶剂热合成方法是制备B〓C纳米晶的一种更可行的途径。

OBJECTIVE: To explore the expression of NF-κB and MuRF1 in denervated skeletal muscle atrophy in rats and the effect of losartan on NF-κB / MuRF1 pathway.

目的：探讨核因子κB、MuRF1在失神经骨骼肌中的表达及氯沙坦对核因子κB/MuRF1通路的影响作用，以期寻找延缓失神经骨骼肌萎缩的新途径。

Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and,or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron,aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil.

传统上可将土壤分成A、B、C三层。A层是位於最上面的一层，含有腐殖质，许多矿物质在该层中沥滤和淋溶。B层是个沉积区，富集了大量的来自A层的粘土矿物质和铁，铝氧化物。C层是现在土壤的母质层，也可能是风化的岩石、来自冰河或冲积层的物质、或早期土壤遗留下来的。

The most important, PsaA/B apoproteins can be synthesized obviously in the dark, which is different with the early report [1] that PsaA/B apoproteins can't be synthesized in the etiolated plants such as pea, barley. This different may come from that the volume and size of the chloroplast is not markedly reduced in dark-grown Y-1 cells and many enzymes involved in photosynthesis are localized on the chloroplast envelope.

同时发现，叶绿体基因编码的PSI核心多肽PsaA/B能够在暗条件下合成，而资料报道[1]高等植物如豌豆、大麦的黄化体中不能合成PsaA/B蛋白，这可能是由于在脱绿的Y-1细胞中叶绿体的量并没有发生明显的减少，且仍具有相对完整的大小和形状，而在叶绿体的被膜上具有许多参与光合作用的酶系统。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
