查询词典 nested

A new trick using Trichogramma brassicae asvectors to transmit Dendrolimus punctatus cypovirus was developed (called"Biological missiles Dp-Ⅰ") to control the Dendrolimus punctatus in the field. Sincethen, we collect the single caterpillar from both areas used Dp-Ⅰand controlled areasevery year, and A nested-PCR-based assay for the detection of those samples wasdeveloped, The results showed that the positive reaction rate of the first year is 40～70％; and second year is 30～80％, on the other hand, the positive reaction rate of thecontrolled areas are 10～40％and 10～20％.

第二章对马尾松毛虫质型多角体病毒的流行病做了初步的调查，应用巢式RT-PCR方法检测从野外释放&生物导弹Dp-Ⅰ&的林区采集马尾松毛虫单虫样本，结果发现：2006年释放&生物导弹Dp-Ⅰ&的王福店林区的松毛虫体内DpCPV阳性率为40～70％，平均阳性率为58％，相应对照区的阳性率为10～40％，平均阳性率为24％；2005年释放&生物导弹Dp-Ⅰ&的丁家畈林区松毛虫体内DpCPV阳性率为30～80％，平均值也为58％，相应对照区的阳性率为10～20％，平均值为16％。

Result The nested PCR assay was specific and there is no cross-reaction with other parasites, such as Eimeria spp., Cryptosporidium spp., Giardia sp., Toxoplasma sp., Trichuris sp. and cattle ciliate. The assay was able to detect as low as 2.85 × 10^(-2) fg of control positive DNA. The results of detection of clinical samples revealed that the assay was coinciding with microscopic examination.

该套式PCR能特异性地扩增出牛源环孢子虫基因组DNA中相应片段，与艾美耳球虫、隐孢子虫、贾第虫等10种相关原虫基因组DNA无交叉反应；最低能检测到2.85×10^(-2)fg的阳性参照DNA；对临床样品检测结果表明PCR技术检查阳性者显微镜检查都为阳性。

The torrential rain is simulated in this paper by using a nonhydrostatic mesoscale model ARPS(V5.2, and by employing the triply single-way nested-grids.

Numerical simulation for this event is performed using the non-hydrostatic, two-way interactive, triply nested grid mesoscale model MM5 and the structure of the inverted typhoon trough is studied. Furthermore, the formation and development mechanism of the inverted typhoon trough as well as the meso-scale vortex are discussed through the budget of vorticity equation.

采用双向三重嵌套网格非静力模式MM5对这一过程进行了数值模拟，研究了台风倒槽的中尺度结构特征，并通过涡度收支探讨了台风倒槽及中尺度低涡发生发展的物理过程。

Lists can be nested (i.e., items of lists can, in turn, be lists), but it takes some care to unnest them when we need to reach for an item

List能够被嵌套（也就是说，list的条目能一次被列出），但是当我们需要伸手获得一个条目的时候，它需要关注解开嵌套。

A nested-RT-PCR technique was established for SCYLV detection from individual viruliferous aphids and plant in early stage of infection, about 80% adult aphids feeding on sugarcane plants with yellow leaf symptom for over 2 weeks showed SCYLV positive by this technique.

但广州甘蔗研究所品种基地源自美国运河点育种场的CP93-1319病株上的病毒与已报道的三个基因型存在较大差异，可能代表了SCYLV的一个新的基因型。本文首次证实华南地区甘蔗上普遍发生的甘蔗绵蚜为SCYLV传毒媒介。

Objective To establish a sensitive, simple to use and low noise nested/multiplex PCR for simultaneously detection of Plasmodium falciparum and Plasmodium vivax.

摘要目的建立简便、灵敏、低本底、可同时检测恶性疟原虫和间日疟原虫的套式/多重聚合酶链反应系统。

In the early days of astronomy before the advent of Newton's f=ma, planetary events were predicted on Ptolemy's model of nested circular orbits -- wheels within wheels.

在天文学的早期，也就是在牛顿的f=ma出现之前，星事都是通过托勒密的嵌套圆形轨道模型，就是那种一个圈套着一个圈的模型来进行预测的。

In the early days of astronomy before the advent of Newton's f=ma, planetary events were predicted on Ptolemy's model of nested circular orbits -- wheels within wheels.

在天文学的早期，也就是在牛顿的f=ma出现之前，对天体事件的预测都是通过托勒密的嵌套圆形轨道模型——一环套一环的复杂模型——进行的。
