结果表明，腔体静止时，射流速度沿腔体中心轴对称分布，腔体中心轴上的速度最大，两侧流速逐渐减小，近壁处为零；腔体转动时，在哥氏力的作用下，射流中心发生偏转，流场相对于腔体中心轴不再对称分布，腔体中各点处的流速分布随角速度而变化，压电射流角速度传感器利用这一特性敏感角速度。

METHODS: Eighteen volunteers(36 eyes) aged 21 to 28 took measurements with different angles of stare, 180°, 90°, 45° from gravity axis respectively, the accommodation was measured by pushup test, and anterior chamber depth, lens thickness, axial length were measured by Aultrasonic.

体例：对18例36眼21～28岁的自愿者，取与重力轴标的目的成180°，90°，45°夹角的3个分歧凝望角度，用移近法丈量眼的调剂幅度，用眼A超丈量前房深度、晶状体厚度、眼轴长度。

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

其中，高温糜棱岩主要矿物变形特征组合为：石英为长矩状或长条状单晶、组构为近X轴的点极密，长石为几乎完全重结晶的集合体，形成温度＞600℃，相当于高角闪岩—麻粒岩相，形成深度＞20km；中温糜棱岩主要矿物变形特征组合为：石英为多晶条带、组构为近Y轴点极密和以Y轴为旋转轴的小圆环带，长石发育核幔结构，形成温度为400～600℃，相当于高绿片岩—低角闪岩相，形成深度为15～20km；低温糜棱岩主要矿物变形特征组合为：石英发育核幔结构、组构特征为近Z轴点极密，长石以碎裂为主，形成温度＜400℃，相当于中低绿片岩相，形成深度为8～12km；碎裂岩则主要代表了地表浅层的变形。

From the base to the crown in axial, the vessel-elements proportion increases in fluctuation, contrary to the ray proportion. The fiber proportions in the regions of base and crown are less than that in the trunk of tree, and fluctuate at 65% or so. The parenchym proportion increases quickly to the 1.3m height of tree, reaching the maximum at 9.52%, and then decreases quickly to the 3.3m height of tree (8.90%); afterward it leveled off and increases slightly.

包头西6.4级地震高烈度区等震线长轴呈NE向，与乌拉山北缘断裂接近，该断裂是包头西6.4级地震的发震构造。2次地震高烈度区长轴与低烈度区长轴走向相差近90 ，这是因为除发震构造外，烈度区还受一组与之交会的共轭断裂活动的影响。1989年大同-阳高6.1级地震，发生在从六棱山腹地向大同-阳高盆地延伸的NNE向大王村-西要泉断裂上，该断裂是大同-阳高地震的发震构造。
