可分度

In this research a new mathematical model - cubic polynom with two given derivatives at end points - was proposed which can good match the S-shpae curve.This model has a number of analytical features:describing the geographic phinomena prosesses in three hierarchies (textural fractal,structural fractal and state fractal); the boundary values of the structural fractal can be considered as the boundary values of interval of scaleless.

在研究中提出了扩展分维表达函数：带导数三次多项式，它能很好地表达反S形分布曲线，具有一系列解析特征：可从三个层次（纹理分形、结构分形和态势分形）上描述地理现象或过程；其中结构分形的边界可近似地看作是非扩展分维无标度区的上下界。

Through the noise analysis between circular oscillators composed of general differential amplifer element and of capacitive coupling differential amplifier element, it is found that the later,due to its band-pass and dynatron characteristics,provides a better anti-noise performance,which can be used in VCO circuits having a high requirement on frequency stability.

The digestive tract reaction grades are similar when used DDP at any time, however, the persistence time and the average disgorging number is lowest when DDP is used at CHEN time (7∶00-9∶00) by the same dosage.

1、同等剂量下酉时应用顺铂，肾功能损害明显低于其他时辰；2、同等剂量下，辰时应用顺铂，患者出现消化道反应分度与其他时辰应用相似，但消化道反应持续时间较短，平均呕吐次数减少；3、临床可根据患者肾功能及消化道反应的具体情况选择顺铂应用时辰。

The most important factor influencing implant survival in sinus augmentation, besides individual surgical technique, is the preexisting bone height between the sinus floor and alveolar crest. The key factor for success is to achieve primary stability. When the available bone height is less than 5mm or the thickness of the cortical bone is inadequate, two stage protocol (elevating the sinus floor to create sufficient bone height first, and then placing the implant at the second stage) is a safe, predictable treatment modality.

上颚窦植牙手术的成功与否，除个人手术技巧外，常取决於剩余齿槽骨之高度(residual bone height， RBH)，如何得到初期稳定度是一重要之关键，当可利用之齿槽骨高度小於5mm或皮质骨宽度不足以支撑植体获得理想初期稳定度时，分二阶段先提高上颚窦高度再植牙，不失为一理想，安全且可预期性高之植牙方法。
