查询词典 reflection angle

It is, e.g., logically impossible that any proper fraction should exceed the ratio 1/1; and again, on a certain definition of "angle," it is logically impossible for any angle to exceed four right angles.

它是，例如，逻辑地不可能任何真分数竟然超过比率 1/1；并且再在"角度"的某个定义上，任何角度超过四个直角是逻辑地不可能的。

The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

There existed significant difference of pubescence angle on leaf blade in breeding lines of TA and NTA populations, and very significant correlation was found between pubescence angle on leaf blade and resistance to bean pyralid.

方差分析表明TA和NTA群体家系间叶片茸毛着生角度也存在极显著的差异。

The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.

研究结果表明，在膨胀锥锥角保持不变的情况下，膨胀锥定径长对膨胀后套管的残余应力没有太大影响，但对套管膨胀所需要的膨胀力有较大影响；膨胀锥锥角对套管最大残余应力没有影响，但对膨胀力的影响十分明显，当膨胀力的径向分力大于材料的抗拉强度时，材料将发生破坏。

It is found that when the angle of the mirror is 2 degree,uncertainty of angle is 2% and uncertainty of reflectance is 0.1%.

在2度时，角度的不确定度为2％，反射率的不确定度0.1％，取得了突破性的进展。

In kick hitting, the moving forward velocity of bat is the highest when the ball was hit at the right moment, which the left elbow angle is almost 180 degrees and the right elbow angle is between 100-110 degrees. In the hitting process, the displacement of body in backward/forward direction and the resultant velocity with kick hitting are larger than those with glide hitting.

一、在击中球瞬间抬腿击球法左肘关节角度接近伸直与右肘关节角度介於1 00度110度时，球棒的前移速度最大；且在整个挥棒过程中前后方向身体重心位移、合速度明平均大於滑步击球法。

The transepicondylar axis of different position has no effect on volume rendering technique measuring the humeral head retroversion angle with multi slice spiral CT.The top view at which lateral epicondyle of the humerus showing minitriangulum and the anterior surface of the distal humerus articulation with the forearm being shaded is more simple,faster and precise for the volume rendering technique measuring the humeral head retroversion angle with multi slice spiral CT.

结论］肱骨头扭转角变异较大，肩关节假体扭转角设计应个性化；肱骨远端不同位置内外上髁轴线对多层螺旋CT容积再现测量肱骨头扭转角没有影响；俯视位观察肱骨，当外上髁露出呈小三角形、肱骨远端前关节面被肱骨头遮盖重叠的位置是多层螺旋CT三维重建测量肱骨头扭转角的更简单、更快捷而且准确的测量位置。
