段长度

The relation of controlling air and solid flow rate in the pneumatic valve with an extended plane segment was also given. Influence of the height of the inlet tube on the control characteristics was discussed as well.

结果表明，隔板高度增加使控制特性由调节特性向开关特性转变，水平通道长度增加使物料流动阻力增加，需与足够高的进料管直段高度相匹配，才能获得良好的控制特性。

The theoretic transfer function of the filter made of N-stage HBFs, and the expression are obtained when N is 1, 2 or 3; the polarization independence of the filter is analyzed, and the relation between the frequency response and the parameter of filter such as the length, beat length of HBFs and the angles between HBFs is studied; finally, some experiments are performed to check the theory, and the result shows to have good agreement with the theoretic result.

从理论上得到了N段双折射光纤构成环镜滤波器滤波特性的结果；具体给出了N为1、2和3时的具体表达式；分析了所构成的环镜滤波器的偏振无关特性；讨论了双折射光纤的长度、拍长、双折射光纤之间夹角等因素对滤波器滤波特性的影响；最后，做了相关的实验验证，所得到的实验结果和理论模拟结果非常吻合，证实了理论的正确性。

According to the biaxial reciprocating gear-driven principle that presents by professor He guo jin in this thesis, the biaxial reciprocating cylinder gear reducer has been designed and interiorinput power of this reducer is forty watt.

本文根据何国金教授提出的两平行轴间多级圆柱齿轮来复传动原理，设计了一台两平行轴大速比来复传动圆柱齿轮减速器，其输入功率为40w，这种减速器中的双联齿轮与轴之间为空套联接，双联齿轮所在的轴段只受弯矩，不受扭矩；也就是说，输入轴只有靠近电动机一端的20mm长度上受扭矩，输出轴只是在靠近外伸输出端与其键联接的齿轮和外伸端部之间承受扭矩，因此轴的扭转刚度高。

Predictions for the Indian side are gloomier still. In April a leading Indian glaciologist, Professor Syed Iqbal Hasnain, measured the East Rathong glacier in lofty Sikkim state. It appeared to have shrunk by 2.5km, or half its length, in a decade.

对于印度境内喜马拉雅冰川的预测则更令人悲观。4月，一位资深的印度冰川地质学家， Syed Iqbal Hasnain 教授测量了 Sikkim 省的东 Rathong 冰川，发现在10年的时间内，这段冰川已经萎缩了2500公里，可以说是其长度的一半。

在巴西橡胶同一茎段一定长度范围内，不同的采胶位置IAA，、ABA含量的差异不显著，表明它们量的分布没有位置效应。

This reporter immediately rushed to the scene, dozens of workers are still busy scene shipment off of trees, These trees higgledy-piggledy heap to a dozen dumplings, a big tree diameter of about 30 cm above were split into about a meter long wooden, Small trees more than 10 cm in diameter was also split into three meters in length.

记者立即赶往现场，十几名工人还在现场忙着装运砍下的树木，这些树木横七竖八地堆了十几堆，大的树直径约30厘米以上的都被截成约1米长的木段，小的树木直径约十几厘米的也被截成3米左右的长度。

The heavy use of abbreviations is a holdover from the days of dBase and other systems where there was a stringent limit on table and field name lengths.

在大量使用的缩写，是从dBase和其他系统的天，那里有一个对表和字段名长度的限制严格缓缴。

Due to the impossibility to compute the exact length of NURBS curve through integration in a short time, it is very difficult to get the deceleration distance and to forecast the point to begin the deceleration stage in real time.

由于不能通过积分方法在短时间内精确计算NURBS曲线的长度，使得在数控加工过程中实时计算减速距离、判断最终减速段开始点变得非常困难。

One is the error on the direction in the length of the loxodrome,and the other is the error on the height direction. Both of them are analyzed in this paper.

当用片铣刀进行铣槽加工时，由于是用直线段包络斜航线，存在刀具干涉问题；刀具干涉会引起螺旋槽长度方向和高度方向上的两种误差。

To indicate nonexistent data in a Microsoft Access database, you can enter a zero-length string into a Text or Memo field.

若要在 Microsoft Access 数据库中指示不存在数据，可以在"文本"或"备注"字段输入零长度字符串。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
