Then a topology control scheme based on NDPSO is put forward. Experimental results indicate that the obtained topology has low overall power consumption, is roust, controls the inter-node communication interference, and prolongs effectively the lifetime of the WSN.

无线传感器网络所具有的能耗有限性和节点资源有限性要求在任务调度过程中进行实时数据交换时要尽量减少传感器节点的功耗，而数据融合能有效减少网络内的数据传输量，减少能源的消耗，并尽可能地挖掘传感器节点的处理能力。

The article analyzes change of its ingredients including Ca(superscript 2+), Fe(superscript 2+) 42(superscript 2+) within different process using chemical analysis, iodine amount and testing chemical value ,and prove the conclusion that the method abouve is one of the best ways to process ruddle through experimental data, which may cause ruddle crispy and easy to be smashed, and get the effctive ingredients, and arsenic's amount can be limited as the value require by codex (0.01%).

利用化学分析法、碘量法以及化合价数的测定法来分析代赭石不同炮制品中的Ca(上标 2+)、Fe(上标 2+)、As(上标 3+)的含量变化，通过实验数据来证实煅醋淬法是炮制代赭石最行之有效的一种理想方法，会使代赭石质地最酥脆，易于粉碎，使有效成份最易煎出，最能使炮制品中冲的含量(0.01%)符合药典要求，建议把砷的含量作为股代赭石的一个质量指标。

According to new individual patient that add monthly from each areas, we collect the amount of 550 valid samples from ratio sampling.

并依照每月新增个数及各地区肺结核病患个案数，进行比例抽样，本研究共计回收有效样本550份。

As people have more and more years to live they have to save more and plan more and they effectively are behaving as if they were younger,''said Sanderson.

当人有越来越多的数年居住他们必须节省更多而且计划更多，而且他们有效地正在举止，好像他们是比较年轻的，''说了 Sanderson。

A few of the herbs that can be used to effectively treat acne are burdock, yellow dock, dandelion root, red clover, and sarsaparilla.

数的草药可以用来有效治疗痤疮是牛蒡，黄船坞，蒲公英根，红三叶草

Since the Schr〓dinger equation is very difficult to be solved for the moleculescontained relatively more atomes, the algebraic approach is more efficient.

由于对原子数较多的分子，其薛定谔方程的求解非常困难，因此处理这一问题的比较有效的方法是代数方法。

The second derivative spectroscopy and Gaussian fitting fluorescence spectroscopy are effective methods to monitor changes in structural characteristics of proteins.

本文研究结果表明，荧光光谱结合导数光谱分析和高斯拟合光谱方法是分析蛋白质构象及功能变化的有效方法。

Mao Wei of researcher of Chinese Academy of Sciences thinks, the strategy that our country IPv4 transfers to IPv6 still is faced with number to weigh a challenge: The sequential estimation of the pressing sex of extinct to IPv4 address problem and generation is not worth whole society badly; Compare with IPv4 network photograph, at present IPv6 network still is in inchoate phase in the development of our country, had not entered extensive deploy to carry out level; IPv6 industry catenary is not perfect still, still be in what the industry grows to form level; Did not form centralized national address management to allocate a mechanism; In national level lack answers IPv4 address extinct and transfer to IPv6 the constituent mechanism with significant aspect, relevant system and measure, also do not have clear schedule.

中科院研究员毛伟认为，我国IPv4向IPv6过渡的战略还面临数重挑战：整个社会对IPv4地址耗尽问题的迫切性和产生的后果估计严重不足；与IPv4网络相比，现在IPv6网络在我国的发展仍处于早期阶段，还没有进入到广泛部署实施阶段；IPv6产业链还不完善，还处于产业发展的形成阶段；没有形成统一的全国性地址治理分配机制；在国家层面缺乏应对IPv4地址耗尽和向IPv6过渡方面有效的组织机制、相关制度与措施，也没有清楚的时间表。

Their shock tactics usually overcame larger enemy forces, but they also had hard fighting against Simba forces trained and led by Cubans. Backed by armor and air support, regular troops of the UN forces subdued the mercenaries.

他们有效的战术常常能击败数倍于己的敌军，但他们常要和受古巴训练的Simba军队艰难地作战，由于有装甲车辆和空中支援，联合国正规部队最终击败了雇佣军。

Analogtodigital converter is very important in digital signal process board,so calculation of the effective numbers of bits is of great importance for evaluation of system performance.

将模拟信号转换为数字信号后再进行处理，是当前信号处理普遍使用的方法，模数转换器就是将模拟信号转换为数字信号的器件，所以计算其有效转换位数对系统性能评估就显得尤为重要。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
