The only difference is that it is for those people who have a bad credit, or in simpler terms, people with a credit history.

唯一不同的是：它是为那些人有不良信贷，或简单地说，人的信用历史。

It is to insist that across Illinois, and across America, a constant cross-pollination is occurring, a not entirely orderly but generally peaceful collision among people and cultures.

这就更加地说明了，在全伊州，乃至全美，一场持续的不同文化之间的互相传播正在进行。在民众和文化方面，这是一场并不太平和的冲突，但一般来说算是平静的。

To investigate whether the expression of cdc2 and cyclin B1 in spermatogenic cells during spermatogenesis is actually a temperature dependent event, in situ hybridization, Western blotting and immunohistochemistry analysis were used to study the expression of cdc2 and cyclin B1 in normal and cryptorchid testis. Results showed that heat would differentially hurt male germ cells in different developmental stages during spermatogenesis, especially the pachytene primary spermatocytes. Most of spermatogonia in contralateral cryptorchid testis were not harmed fatally by heat as yet, indicating that spermatogonia could resist to beat to a certain extent. In this case spermatogonia could develop to pachytene/diplotene primary spermatocytes, but they could not acquire the ability to complete the transition from mitosis to meiosis, and then appeared to go through apoptosis. Therefore, we could not find the descendants of meiosis: secondary spermatocytes and round spermatids, elongated spermatids and spermatozoon. The abdominal temperature had no significant influence on the transcription of cdc2 and cyclin B1 in the spermatogonia and pachytene/diplotene primary spermatocytes. In normal rabbit testis, cyclin B1 increased in the pachytene/diplotene primary spermatocytes before meiosis and reached its peak in the spermatids.

为了解精子正常发生过程中cdc2和cyclin B1表达的低温依赖性，我们利用原位杂交和免疫组化等方法，研究了正常和隐睾精子发生过程中cdc2和cyclin B1的转录和翻译调控活动，结果表明：（1）热对各阶段的雄性生殖细胞都有损害，粗线期的初级精母细胞尤为敏感，实验性隐睾内的精原细胞尚未完全受到"致命"影响，说明精原细胞对热有一定的耐受性，但即使成为粗线期／双线期初级精母细胞，却未能获得由有丝分裂过渡到减数分裂的能力，呈现不同程度的凋亡，所以在整个切片中找不到源自减数分裂的产物----次级精母细胞、圆形精子细胞，更谈不上长形精子细胞和精子的形成；（2）腹腔高温未明显地影响隐睾精原细胞和粗线期/双线期初级精母细胞中cyclinB1和cdc2的转录，说明高温并不是通过影响cyclin B1和cdc2的转录活动而导致生精过程阻断的；（3）正常兔睾丸组织中，〓在精原细胞和粗线期／双线期精母细胞中均有表达：cyclin B1蛋白在减数分裂前期的粗线期／双线期初级精母细胞中的表达量增加，于变态末期的精子细胞中达高峰。

The domain structure of TbFe〓Ti〓 single crystals in different crystal planes with the increasing of Ti content was first investigated.

本论文首次揭示了1∶12型TbFe〓Ti〓单晶不同晶面的磁畴结构，直观地反映了材料的各向异性从x=0.85的易面到x=1.0，1.3的易轴的转变，以及面内各向异性的变化对单晶磁畴结构的影响。

But systematic research concerning continuous mono-cropping grafted cucumber obstacle isn't reported. This paper systematically studied the effect of continuous cropping soil on grafted cucumber in aspect of its growth, yield and edaphon in pot experiments. Further more, root exudates of squash and grafted cucumber were collected by solution cultivate and adsorption of XAD-4 resins, and bioassay of the root exudates was did with cucumber and squash as receptors, studied allelopathy of grafted cucumber and squash root exudates on cucumber and squash , physiobiochemistry as well as.

本项研究采用盆栽试验以不同连作年限的土壤为基质比较系统地研究了连作年限对嫁接黄瓜的生长、产量和土壤微生物的影响；采用水培和XAD-4树脂吸附法分别收集嫁接黄瓜和砧木南瓜的根系分泌物并以黄瓜、南瓜为受体进行生物活性测定，并对嫁接黄瓜及其砧木南瓜根系分泌物化感作用的生理机制进行了初步探索。
