查询词典 Np

The control chart based on the geometric distribution(g-type chart) has shown to be competitive with p or np chart for monitoring the proportion especially for application in high quality manufacturing environments. However when the cases with LCL=0 occur, plotting values beneath the LCL is impossible given the non-negative nature of units, such type of lower control limits no ability to detect rate increase.

但是由于几何控制图的自然下限的问题，在其使用过程中若控制下限LCL＜0，则取其自然下限为0，这使得几何控制图在此情况下对于检测不合格品率p的增加是几乎不起任何作用，而此问题也是实际中我们最需要检测并作判断的问题。

A two-year field experiment was conducted to investigate ammonia volatilization from Gleyed paddy soil in the Taihu Lake region. The experiment was designed to have four N levels 0, 180, 255, 330 kg hm^(-2 and four P205 levels 0, 30, 90, 180 kg hm^(-2, forming six NP combinations (CK-N0P0, LN-N180P90, OPT-N255P90, LP-N255P30, HP-N255P180 and HN-N330P90). Ammonia volatilization was measured with the enclosure method.

在太湖地区乌栅土上，采用田间小区试验连续两年研究了施氮量为0、180、255、330 kg hm^(-2)，施磷(P2O5)量为0、30、90、180 kg hm^(-2)的6个组合（对照N0P0低氮N180P90、优化N255P90、低磷从N255P90、高磷N255P90、高氮N330P90）以及三个施肥时期对稻田氨挥发损失的影响，氨挥发采用密闭室间歇通气法测定。

In the study, two genetically distinct kinds of rat – one an innately heavy-drinking strain bred to prefer alcohol, the other strain bred to not prefer alcohol -- learned to give themselves nicotine injections by pressing a lever.

在这个研究里，有两类遗传不同的老鼠被构建：一类被培育成天生地喜欢喝酒的酒鬼，称为 P 型老鼠，而另一类被培育成不喜欢饮酒的老鼠，称为 NP 型老鼠。

Among the present methods for protein detection using aptamers, some of them are with high sensitivity, some with high sensitivity but require expensive instrument. This study takes use of aptamer modified by Au naloparticle to construct a new method for protein detection. This methos can fastly detect proteins with high sensitivity compairing to other methods, and requires no expensive instruments. It has wide application prospect and large market value.

当前利用Aptamer的蛋白质检测方法，有的灵敏度不是很高，有的虽有较高灵敏度，但需要昂贵的仪器，本研究利用金纳米颗粒(Au nanoparticle，Au NP)修饰的Aptamer来建立一个蛋白质检测的新方法，与其他方法相比，本方法有较高灵敏度、不需昂贵仪器，简单快捷，具有广泛的应用前景和巨大的市场价值。

The gene typings of the bacterial from lower respiratory tract secretion and gastric aspirates were taken by plasmial profile analysis,restriction andonuclease fingerprint analysis and Genome Macrorestriction Pulsed Field Gel Electrophoresis in the same phenotype bacteria.

以气管切开或插管患者为研究对象，用防污染标本刷采集标本，由细菌表型分型，直至质粒DNA图谱、酶切图谱、全基因组DNA稀有位点酶切脉冲电场电泳（genome macrorestriction pulsed field gel electrophosresis， GM PFGE）等基因分型方法，前瞻性观察NP的发生情况。

PATIENTS AND METHODS: The study was a controlled clinical trial at two tertiary care centres of patients with SLE according to the ACR criteria, with incident (no more than 15 days) onset of severe NP manifestations such as seizures, optic neuritis, peripheral or cranial neuropathy, coma, brainstem disease, or transverse myelitis.

患者和方法：2个研究中心进行了临床对照试验，系统性红斑狼疮根据ACR标准进行诊断。
