精确地

Scientists often cannot date precisely archeological or prehistorical findings.

科学家们常常不能精确地鉴定考古或史前期发现的日期。

However, it takes too much time and space for simulating a model with a relative large scale. A pseudospectral time domain method has the advantage of saving time and computer memory for the same simulation accuracy as that of FDTD.

通常采用的时域有限差分法在网格足够细的情况下能够精确地模拟井中雷达，但对于相对较大的模型，要得到较好的精度其所需要的时间和计算机内存都非常大。

The mechanism of consumer segmentation is based on demographic, psychographic factors such as age, ethnic background, value, belief and emotional subtlety. It seems no longer apt to probe for buyer's motivation. If we understand core groups precisely better, the "New Values"-driven approach will make them buy.

消费市场区隔化，是以人口统计与心理描绘诸如年龄、种族背景、价值、信仰与细微的情感洞察等作为调查机制，然而，这样作法已经无法探测买家的购物动机，如果行销人愈能精确地理解核心族群，那麼「新价值」驱动的品牌行销法则愈能让卖家掏钱购物。

We have previously proposed a quadratical constraint based method,referred to as integrated peak sidelobe control,which can precisely control the peak sidelobes and produce stable mainlobe shapes of adaptive beampatterns.

该方法可以精确地控制峰值副瓣电平并产生具有稳定的主瓣形状的自适应方向图。

"It seems likely they will leave this up to comitology to define this exactly," said Sanjeev Kumar.

Sanjeev Kumar 说：&看起来他们可能会把这个问题留给一个委员会来精确地界定。&

How this wonderful system started and what kept it working with such wonderful accuracy is largely a mystery but astronomers tell us that it is only one of millions of similar systems in spece ,and one of the smallest.

这个奇妙的星系是怎样开始的，什么使它保持精确地运行，这是一个很大的迷。但是天文学家告诉我们太阳系只是太空里几百万个相似的星系中的一个而且是最小的一个。

Consequently,three laws are revealed: 1 There exists the possibility of significant difference among priming effects extracted from the vaseline values,the completion rates of which are different,if the number of tested people is small;2the Superconsciousness scope method not only is superior to both the sublimin...

结果发现：（1）如被试数量较少，以不同补笔率为&基线值&所求得的启动效应之间发生显著差异的可能性存在；（2）超意识广度法能克服&阈下呈现刺激法&&分散注意法&的不足，为内隐记忆提供有利的识记情境；（3）&二次比较法&能为正常人内隐记忆的存在提供更为直接、可靠的证据，并能客观、精确地计量启动效应。

Based on the characteristics of the chip we designed to control the hydraulic servo system for the core of this system, control circuit valve using digital potentiometer, through programming, automatic regulation resistance, high AD698 and accurately by an LVDT valve mechanical displacements converted single polarity dc voltage, through the simulation, the design of PID algorithm of closing valves, the degree of control system and superordination machine, realize the valve control circuit of adjustment and control.

基于上述特点我们设计了以单片机为控制核心的液压伺服阀控制电路，本系统采用数字电位器，通过编程自动调节电阻值，采用AD698 与LVDT 配合，高精确地将阀门的机械位移转换成单极性直流电压，通过模拟PID调节算法，设计实现了对阀门开合程度的控制，该系统与上位机进行通信，实现对阀门控制电路的调试及监控。

In order to identify precisely the species of parasites eggs in kimchi and other related products and distinguish from the plant-parasitizing nemotode eggs, we researched the detection technique of Ascaris egg looked as the highest polluting risk of kimchi. The specific fluorescence quantity PCR method was established by using the Ascaris suum genome DNA as positive control,and the optimum way of breaking the eggshells in liquid nitrogen and thawing at 37℃, and the detection method of single egg.

为了精确地对从泡菜及相关产品中发现的寄生虫卵进行种类鉴定，同时与植物本身的线虫卵进行区别，我们在上述研究的基础上，以污染泡菜风险最高的蛔虫卵作为检测目标，进行了模拟阳性泡菜样品中携带蛔虫卵的荧光PCR检测技术研究，即以猪蛔虫基因组DNA为模板，建立了蛔虫特异性荧光PCR检测方法。

The accurate theoretical heats of formation for 56 derivatives are obtained through designing the isodemic and isogyric reactions with the tetrazole parents as the reference compounds.

通过设计等键和等电子对反应，以四唑母体为参考物，首次精确地报导了系列56个四唑衍生物的理论生成热。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
