Through establishing the functional of the source pulse which is based on the concept of "usable energy" in the received pulse and then extremizing the functional by means of the calculus of variations, the mathematical models of the optimized source pulse waveforms are shown to be associated with the eigenfunctions of a homogeneous Fredholm linear integral equation of the second kind. An efficient algorithm is developed for numerically solving the integral equation models.

论文研究了基于延迟反射脉冲序列无源标签的UWB RFID系统的基本工作原理并进行了详细的信号描述和分析，通过建立基于接收脉冲"有效能量"概念的源脉冲波形函数的泛函和使用变分计算泛函极值，得到了相关于第二类齐次Fredholm线性积分方程特征函数的源脉冲波形最优解数学公式模型，并开发了一套有效的数值求解算法。

Condusions GIP is a very rare chronic interstitial pneumonia, and has no characteristic clinical manifestations.

结论GIP是非常罕见的慢性间质性肺炎，无特异性的临床表现，影像学表现类似于特发性间质性肺炎。

There are no significant influences observed in the protein content of grain, gluten content, flour quality, and dough rheological properties among different densities of population.

种植密度对籽粒蛋白质含量、面筋含量以及面粉品质和面团流变学特性无显著影响。

I proudly explained: For her children, my mother learnt everything, including haircutting. She was really good at it. But unfortunately she hasn't seen her overseas son for a long time.

我自豪地解释道：为了儿女，我母亲什么都学过，无活不会，当然包括理发，并且技术高明。

Isolated ileitis detected in asymptomatic patients undergoing polyp screening or surveillance does not evolve into CD on follow-up, despite endoscopic and histologic overlap with findings typically seen in CD.

随访发现，无症状患者存在的孤立性回肠炎（通过结肠镜筛查或复查息肉而发现）不会进展成CD，即使其内镜下特征和组织学特点与CD特征有重叠。

The multivariate polynomial interpolation problem is a classical mathematical problem that is widely used in many fields, such as multivariate function list, surface design and finite element method. In recent years, multivariate polynomial interpolation has been focused by many people, of which the geometric topological struction of sets of interpolation nodes is also much concerned by us.

多元多项式插值问题是一个十分具有研究意义和实际应用价值的数学问题，它广泛应用于多元函数列表，以及曲面的外形设计和有限元法等诸多领域，近年来多元多项式插值越来越受到人们的广泛关注，其中有关插值结点组的几何拓扑结构问题也是人们十分关注的内容。1998年，梁学章和吕春梅在文献[2]中借助代数几何中的有关理论，进一步讨论了沿无重复分量平面代数曲线上的Lagrange插值问题，并应用Cayley ？

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein of virus, serology detects virus during peculiar immunology reaction of antibody and antigen. But it can't detect virus without CP and preparing antibody need more time. The molecular biology method is based on nucleic acid to detect virus. This technique has high sensitivity, strong veracity, wide suitability etc.

生物学方法是依据病毒侵染后在甘薯或指示植物上的外观症状进行识别，但检测速度慢，易受季节限制；血清学技术是利用病毒外壳蛋白的抗原性，据特异性的抗体抗原免疫学反应检测病毒存在，但制备抗血清需时间长，对含量少和无蛋白外壳的病毒无法检测；分子生物学方法是以核酸为基础，通过检测病毒核酸来证实病毒的存在，该技术具有灵敏度高、特异性强、适应范围广等特点。

There are several histologic definitions of basosquamous carcinoma ranging from a characteristic combination of BCC and squamous cell carcinoma with or without a transition zone, to any BCC with evidence of keratinization.

临床上存在许多组织学定义，包括基底细胞癌合并鳞状细胞癌，有或无移行带，或者是所有存在角质化的鳞状细胞癌。

It turned out to be that Ling comprehended many low class tricks in Wu-lin, including the dazing incenses and knockout drops. Tung's anesthetic is actually one kind of them, too. Therefore, when tasted something weird in the soup then, she told, on the quite, a servant to prepare the freshening mint ointment after meal and wake her with it if she falls asleep later. Once the drug effect was relieved, Ling bought a best horse and hurried to the everwinter valley. So, she arrives here not much later than Shin does.

原来金灵以前在跟父亲斗智，企图闯出无银堡时，曾学过有关迷香和蒙汗药等江湖伎俩，童氏安神茶当然也属此类，当时她发现汤的味道有异，就在饭后悄悄嘱咐了一个家仆，要他准备好提神醒脑的薄荷油膏，要是之后发现自己昏睡，就以此将自己弄醒，等解了药性之后，她便买了一匹最好的骏马，向长冬谷直赶而来，所以只比童心，晚了半个时辰左右

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。
