The results were summarized as follows:(1) the 4-week interval retest reliability for the Decidedness, Comfort, and Reasons scales were .69,.80, and .89, respectively, and for the subscales of the Reasons scale ranged between .78 and .85;(2) the alpha coefficients for the three scales were .85,.91,.97, and for the subscales of the Reasons scale ranged between .78 and .93;(3) there was a positive correlation between the Decidedness scale and the Comfort scale, and both scales were negatively correlated with the Reasons scale;(4) career indecision was found to be correlated as expected with state-trait anxiety, career beliefs, and perceived career barriers;(5) there were no significant differences between social science group and natural science group;(6) the only significant gender difference was found on the Career Choice Importance scale of the Reasons scale; and (7) there were significant grade differences on all the CCFI scale scores, with higher school grade level students showing greater decidedness.

本量表共分三部分：定向量表，安适量表及原因量表。其中，原因量表尚包含「环境资讯」、「抉择时机」、「双趋冲突」、「焦虑犹豫」、「科系因素」、「外在阻力」及「自我认识」七个分量表。做答方式采六点计分，从「非常不符合」到「非常符合」。信度方面，间隔四周的再测信度，定向量表为。69，安适量表为。80，原因量表为。89（分量表介於。78至。85间）。Cronbach alpha系数，定向量表为。85，安适量表为。91，原因量表为。97（分量表介於。78至。93间）。在效度方面，定向量表与安适量表呈显著正相关(r=。67)；两量表与原因量表呈显著负相关(r=-。77及-。75)；原因量表各分量表的内部相关低於各分量表与总分的相关。大学生的生涯定向程度、对生涯定向状态的安适程度及生涯未定向原因的类型三者与特质焦虑、情境焦虑、生涯信念及职业抉择阻力有关。

The ADWM filter has the features of directional filter, which is especially effective at preserving edges, and the features of center weighted median filter, which can reduce random noise, and moderate amounts of impulsive noise also, to some extent, as well as preserve the details via adaptively determining the weight of the center pixel according to the lowest variance of pixels within all the sub-windows.

ADWM滤波器既有定向滤波器的特征，也有中心加权中值滤波器的特征。定向滤波器可以有效保持边缘，而中心加权中值滤波器对减少随机噪声尤其有效，同时也能在一定程度上减少冲击噪声的数量，并根据子窗口内像素的最低方差自适应地调整中心像素的权值以保持图像的细节。

The local Directional drilling is just staring in terrane, the equipments and the technologies cant satisfy far and far the spot construction needs, according to current circumstance and considing the existed equipments, the author put forward drilling by air hammer in terrane , having designed compounded-drilling tools,and recommended technology parameters.producing experiments have obtained good achievements in economic and in techniques.

国内定向钻进铺管技术在岩层只是刚刚起步，设备、工艺远远不能满足现场施工需要，本文针对国内、外岩层定向钻进非开挖设备及工艺现状，结合国内大多施工单位的已有设备，提出岩层空气潜孔锤导向钻进工法，设计了适合岩层钻进的实用钻具，并提出具有针对性的工艺参数，生产性试验取得了良好的经济技术指标。

Around the age of eighteen, I realized that orienteering wasn't that difficult after all, and as my older siblings had already chosen to become orienteers, it was easy for me as a little sister to follow their footsteps.

大约在我十八岁的时候，我逐渐体会到定向越野其实没有那麼难，而且我的大哥大姐们，也都决定成为定向越野选手了，对我来说，身为一位小妹，能跟随著他们的脚步是比较容易的。

In this paper, the flux oriented angle of stator flux oriented vector control is deduced by the voltage vector space angle of the direct torque control, and mathematical model is set up based on the direct and quadrature axis component of the stator current.

将直接转矩控制与定子磁链定向矢量控制相结合，利用DTC中电压矢量的空间位置角，推导出SFOVC中的磁链定向角，然后根据旋转坐标系中的d轴和q轴电流分量，建立定子磁链估计的数学模型。

In the new models, there is no need to level and orientate theodolites for self--locating of GeoIMS. Comparing with the common model, the new models can eliminate the errors of levelling and orientating in self-locating of GeoIMS. So it is pos sible to improve greatly the precision of GeoIMS in the new models.

与传统模型相比，这几种新的自定位模型或者不要求仪器严格整平，或者不要求仪器进行相对定向，因此不再受仪器的整平、定向等误差的影响，从而使得系统的整体测量精度大幅度提高成为可能。
