Through S-wave polarization scanning mode of ultrasonic impulse testing, rock samples with three different properties are measured to evaluate the variation of S-wave velocity in three perpendicular coordinates. By analyzing S-wave splitting of three directions and polarization of the maximum or minimum speed S-wave amplitudes, we think that the velocity orthotropy and fracture orientation observed in the grain sandstones and crack marble samples can be estimated in terms of the polarization and velocity of S-wave. Also, perpendicularity characteristics on the two types of rocks can attribute to the bedding and structure of rocks (directional grains or crystallize).

在实验室通过选择了三种不同岩性的岩石，采用超声脉冲测试方法中的横波偏振扫描方式，观测了岩石样品三个坐标方向上的横波速度变化，通过分析三个传播方向上出现横波分裂的差异，以及出现最大或最小快慢横波振幅的偏振方向发现，可从横波偏振方向和速度值判断出纹理砂岩和裂隙大理岩样品存在不同程度的速度正交各向异性和裂隙方向等特征，认为这两种岩石的正交特性的原因是岩石的层理或裂隙与岩石本身的结构构成的。

There are two uses of"you……you……"pattern in contemporary Chinese--- one is parataxis ,another is non-parataxis .

该格式可分为并列式和非并列式两类，本文从形式特征及语义等方面对这两种句式尤其是并列式"又……又……"进行了考察、分析，同时通过对这两种句式的对比，归纳出两者之间的差异及使用条件。

The paper presented a method of detecting long-range correlation in a signal--detrended fluctuation analysis and applied it to diagnose gear faults. Two key problems, i.e. scaling range and polynomial order of fitted trend, were discussed. Scaling exponent was extracted to be as a detector for diagnosing five types of gear faults, their were normal, spalling, tooth broken, wearing and cracking.

探讨了一种检测非平稳信号中长程相关信息的方法--利用去趋势波动分析（detrended fluctuation analysis，DFA）方法来诊断机械故障，着重研究DFA的尺度范围选择、趋势拟合阶数选择等关键问题，提取尺度指数作为诊断的特征参数，应用于齿轮的正常、剥落、断齿、磨损、裂纹等五种状态诊断，正确率达96％以上。

At last,Humecompared these two and made a conclusion that polytheism is morebetter than theism.

最后，他将多神教和一神教这两种形式的宗教特征和后果加以比较，而在每一种情况中，比较的结果都是对多神教有利。

Characters used for segregation of some species and infraspecific entities are very unreliable and variable (e.g., plant size, branching habit, degree of pubescence, color, shape of inflorescence etc.).

用于分离一些种和种下实体的特征是非常不可靠和易变的(例如，植株尺寸，分枝类型，短柔毛程度，颜色，花序的形式等等的)。

A hybrid preventive maintenance model for equipment maintenance features was established based on two maintenance strategies of equipment failure rate decay and age decrease.

结合故障率衰减和年龄减小两种典型预防性维修策略，建立了一种适合设备维修现场特征的混合预防性维修模型。

A general idea is that larger letters and smaller letters of justice are only a reflection of a kind of abstract social order, which is far away from actual social lives. Hence essentially it only can imply a peaceful state of soul, which just is the so-called Platonic Justice. No doubt, it is of distinct character of religionism.

总的观点是，大字的正义和小字的正义只是一种抽象的社会秩序的反映，它是远离社会现实生活的，从而在根本上，它只能体现为一种内心的平和的心境，这也就是所谓的"柏拉图式的正义"，它具有浓厚的宗教主义特征。

The gemmological characteristics and spectra of a type of rock crystal containing tube like inclusion s appearing in market in recent years are studied.

对近年来在国内市场出现的一种含管状包裹体的水晶制品进行了详细的宝石学特征及谱学研究，获得的主要结论有：该类型水晶是以 Z( 0 0 0 1 )为种晶板、在 2 80～ 3 3 8°C的条件下合成的；富含包裹体的部分可能是合成过程早阶段的产品。

Methods8 species of its fruit were observed under light microscope and scanning electron microscope, and most of them were examined for the first time.resultsthe shapes of fruit are usually different from each other;there are obvious differences in color;the types of ornamentation of fruit coat are mainly similar to ruga and washboard.

方法对菊属8种植物的果实进行了光学显微镜与扫描电子显微镜下的形态特征观察研究，其电镜资料为首次报道。结果果实形态多为椭圆形、卵形和矩圆形；颜色为灰褐色至黑色；表面纹饰以皱褶状和搓板状为主。在大小、表面纹饰等方面表现出明显的种间差异。

The invention relates to a code device, which is characterized in that: the device safety storage section has a blank mark which comprises at least two conditions as effective and ineffective; when the blank mark is effective, the code device only can be logged in by the device initial user; and when it is ineffective, the code device can be logged in by other user without the initial user.

本发明提供一种密码设备，其特征在于：在设备安全存储区内设置一空白标志，该空白标志至少具有有效及无效两种状态，当空白标志有效时，密码设备只接受设备初始用户的登录，当空白标志无效时，密码设备不接受设备初始用户的登录，其它用户可以正常登录。
