Through exploring the internal logic interconnection among various key elements embedded in Berlins body of thought, it summarizes the threshold logic underlining the following study of Berlin, i.e., the untiring efforts to defend the validity of liberalism under the superficial historic relevance. The basic structure of study based on this threshold logic is then outlined.

结果 兄语言频率气导听力提高47 dB，听阈为25 dB；妹提高52 dB，听阈为28 dB，分别随访8年及1年余，听力稳定。

Then the corrected average hearing threshold of 0.5 kHz, 1 kHz, 2 kHz, 4 kHz and the average hearing threshold of 1 kHz,2 kHz,4 kHz were compared for analyzing the impact of their differences on hearing grades.

为了达成一致，我们在实际操作中对0.5k Hz听阈值进行了修正，对0.5kHz听阈值在计算平均听阈值时的影响进行了分析，结果报告如下。1对象和方法1.1样本和对象以2001年《贵州省年鉴》人口统计数据为基准，按容量比例概率抽样法

Methods One hundred and twenty cases (165 ears) of tinnitus and/or hearing loss were differentiated into five syndrome patterns according to the theory of traditional Chinese medicine: invasion of wind-heat, liver-fire up-stirring, stagnation of phlegm-fire, kidney-essence deficiency and weakness of spleen-stomach. Hearing threshold of pure-tone, function test above hearing threshold and matching of tinnitus frequency and loudness were carried out in all cases and the data were analyzed by SPSS statistical software.

方法］选择具有典型中医证候表现的耳鸣耳聋患者120例（165耳），经传统方法辨证为风热侵袭、肝火上扰、痰火郁结、脾胃虚弱、肾精亏损5个证型，分别进行纯音听阈测试、阈上功能测试、耳鸣频率及响度匹配，数据经SPSS软件进行统计学处理。

When usingt R =0.3 as a threshold of hazard assessment, threshold value range of color line was shown in stress wave tomogram.

使用t R=0.3作为危险性评价阈值时，在应力波断层图像中以彩色线条显示阈值范围。

In this algorithm, by initially setting a larger threshold of rate-distortion slope and marking the channels that their rate-distortion slopes are larger than the thresholds in each coding block as "selected state", and then decreasing the threshold step by step until the sum of the rate of those selection exceeds the predefined rate limitation, an approximate optimal truncation point will be obtained.

本算法通过初始设置一个较大的长度－失真斜率阈值，将每个编码块中长度－失真斜率大于该阈值的通道置为"选入"状态，逐次减小该阈值并重复上述过程，直到状态为"选入"的通道的累积码流长度大于设定的码流长度，得到近似的最优截断点，再采用舍弃最小斜率的方法获得最优截断点以实现码率控制。

Firstly, the integral-differential equation described the radiation field evolution is derived, and then the instability of its solution is also investigated analytically. By using the perturbation and iteration method, the threshold detuning and threshold linear growth rate of the unstable solution are analyzed and discussed in detail.

首先，建立了一个描述辐射场演化的积分一微分方程，解析分析了系统解的不稳定性，并采用线性方程解的微扰迭代方法进一步对系统不稳定解出现的失谐量阈值和线性增长率阈值等作了详细讨论。

Coordinate sequence method is made up of the instruct information of polygon boundary x, y coordinate. It is the easiest polygon vector encoding method. The file structure of this method is easy, but because of the polygon boundary has stored two times, it will produce data redundancy, moreover, short of neighbor threshold information; Tree index encoding method make all the boundary points digitizing, store the coordinate sequence, connect the point index to boundary line, and then connect the line index to other polygons, so as to the tree index structure has came into being. It eliminates neighbor polygons boundary data redundancy problems; Topology structure encoding method is a method which by setting up a complete topology relationship structure, resolve the neighbor threshold and island information process problem. However, it makes arithmetic more complicated and makes database bigger.

坐标序列法是由多边形边界的x，y坐标对集合及说明信息组成，是最简单的一种多边形矢量编码法，文件结构简单，但多边形边界被存储两次产生数据冗余，而且缺少邻域信息；树状索引编码法是将所有边界点进行数字化，顺序存储坐标对，由点索引与边界线号相联系，以线索引与各多边形相联系，形成树状索引结构，消除了相邻多边形边界数据冗余问题；拓扑结构编码法是通过建立一个完整的拓扑关系结构，彻底解决邻域和岛状信息处理问题的方法，但增加了算法的复杂性和数据库的大小。
