By torque split method and combination of a full-toroidal variator, an epicyclic gear train and a fix-ratio gear, the full-toroidal traction IVT is capable of changing the reduction gear ratio up to plus infinite or minus infinite.

摘要牵引式全环面无限变速器是采用转矩分流方法，把全环面可变耦合器与行星齿轮机构及定速比齿轮机构结合起来，其减速比可以达到正无穷和负无穷，即变速时输出轴可以由正转经零转到反转，因而命名为无限变速器(Infinitely Variable Transmission，简称IVT)。

A pair of primers were designed based on M1 gene sequence of known H5N1 Avian influenza virus.M1 gene was cloned from total RNA,extracted from tissue of H5N1 subtype virus inoculated embryo by reverse transcriptase-polymerase chain reaction using high proofreading polymerase(Pyobest~TM DNA Polymerase),and expressed using Invitrogen champion~TM pET directional TOPO expression system.Recombinant protein containing polyhistidine(6xHis) tag in N-terminal about 29.8kDa in size,wac obtained and purified.

Methylation analysis showed there were different levels of methylation in Zizania latifolia, but high level of methylation in rice

甲基化分析表明，反转座酶序列在菰中有不同程度的甲基化，但在水稻中均为高度甲基化。

In this study,one pair of specific primer for mature chicken interleukin-18(ChIL-18) cDNA was designed and synthesized according to the previously published gene sequence of ChIL-18.The full length cDNA gene of ChIL-18 encoding mature active protein was amplified from LPS–stimulated MDCC-MSB1 cells by Reverse Transcription-Polymerase Chain Reaction.Then it was cloned into pMD18-T vector. Sequencing analysis showed that the nucleotide sequence of this ChIL-18 mature protein gene was 5l0bp including the stop coden and the same as the published ChIL-18 cDNA sequence by Schneider K.

本研究根据已发表的ChIL-18成熟蛋白(mature ChIL-18，mChIL-18)的cDNA基因序列，设计一对特异性引物，应用反转录-聚合酶链式反应(reverse transcription-polymerase chain reaction，RT-PCR)技术从脂多糖刺激10小时活化的马立克氏病成淋巴细胞样细胞系MDCC-MSB1的cDNA中扩增出编码鸡IL-18成熟活性蛋白的全长基因，对扩增片段进行T-A克隆，经PCR、酶切鉴定及测序验证，成功获得ChIL-18成熟蛋白完整基因的克隆。

If we just talk about inversion of control without a real life example, things will soon get boring.

如果我们只是控制反转说，但没有一个真正的生活中的例子，事情很快就会乏味。

The essence of differential display method is to use for reverse transcription an anchored oligo-dT primer which anneals to the beginning of a subpopulation of the poly tails of mRNAs.

该差异显示方法的本质是使用为反转录一锚定寡脱氧胸苷引物的退火的一个聚尾巴 mRNA的。

There is no opportunity to reverse the field and go back to the "good old days", because the crudes from which the old asphalts were made and conditions under which they were utilized are simply gone.

这是没有机会反转到以前&好日子&的，因为原来用来制作沥青的原油及其被利用的条件已正在消失。

In the second part, the current-voltage characteristics of the sensors were measured, their charge ionic mobilities were measured with polar inversion method and their ionic numbers were computed. It has found that ionization effect of some binding ions against a critical humidity took place in switchable humidity-sensitive materials, the effect is that some binding ions in materials turn into free ions when a given ambient humidity is reached called a critical humidity, avalanching conduct electricity occurs in materials.

在第二部分中，测试了高分子电阻型湿敏元件和开关型湿敏元件的伏—安特性，并用极性反转法测试了其导电离子的迁移率以及计算了相关的导电离子数目，发现了开关型湿敏元件的束缚离子的最小湿度电离效应：当环境湿度达到或者大于一特定湿度时，这一特定湿度称之为最小湿度，材料中某些束缚离子才电离成自由的导电离子，形成雪崩式导电。
