恒定

For narrow-band signals, three uniform linear arrays, whose grating lobes are not overlapped by setting the angles between the arrays and the same pointing of main-lobes, are used and then multiplication of three patterns is operated to reduce the grating lobes of large-spaced array, which makes the array operate in broad band. For wideband or ultra-wideband signals, array pattern in the whole frequecy band is identical by designing the frequency-dependent weighting coefficients based on the Bessel function, and therefore grating lobes in high frequency parts are suppressed.

对于窄带接收信号，利用三个相交的大间距均匀线阵，通过设置它们之间的角度和主瓣指向相同使各自的栅瓣位置错开，然后把三个方向图相乘从而抑制大间距阵列栅瓣，因而适用于宽频带工作；对于宽带接收信号，利用Bessel函数设计与频率有关的加权系数，产生整个信号带宽内恒定的方向图，从而抑制了高频部分的栅瓣。

As a result of oil mixed with air, the system bulk modulus and the leakage coefficient is no longer a constant during the process of pump-control-motor running.The conventional PID controller can't meet the requirement of the dynamic characteristics of the system.

泵控马达系统在运行过程中，由于油液中混入了空气，系统体积弹性模量和泄漏系数不再是恒定的值，常规 PID 控制不能很好地满足系统动态要求。

Results:(1) The two nerves were found anatomically related at 5～10 mm and 26～30 mm respectively following hypoglossal nerve entering the muscle.(2)The diameter of the two nerves were observed to match well with each other or with the main branches at 10 mm following the branching of hypoglossal nerve.(3) At 6～10 mm prior to the branching of hypoglossal nerve there was a branch going to the lingual muscles and plexiform of lingual nerve.

结果：(1)舌下神经与舌神经之间有二个恒定的联系部位，即舌下神经分支进入舌肌后最初5～10 mm处和26～30mm处；(2)舌下神经与舌神经最佳吻接部位，我们认为应在舌下神经主干分叉后10 mm左右；神经直径测量也发现神经直径与舌神经主干和分支直径较为匹配，且此区有利解剖，便于神经吻合；(3)舌下神经分叉之前，在神经干上方距分叉约6～10 mm处有一较固定分支，参与分布舌肌并与舌神经呈丛状结构。

mams is a safe drug carrier. the preparation method and changes of dosage form exert no action on anticancer activity of 5fu. the inhibitive action is significantly enhanced after 5fumams is combined with constant external magnetic fields.

结论mams可作为安全的药物载体；5fumams制备方法和剂型的改变不影响5fu的抗癌活性；联合恒定外磁场5fumams的肿瘤细胞抑制效应显著增强。

The mature schizont contains 4-8 merozoites, with one pigment granule, they hardly be observed the cytoplasm, not tend to the pole of host cell and has no"the tie structure"in the mature schizon, the merozoite has no refractive globule.

成熟裂殖体含有4-8个裂殖子，并有一颗恒定的疟色素粒，没有&领带结&结构，裂殖子没有折光球，成熟裂殖体几乎观察不到细胞质。

Experimental results show that the proposed method is more effective than the constant velocity migration.

实测数据处理结果显示该方法性能优于恒定波速成像。

The bias drift at invariable temperature is minished througn Kalman filter which is based upon ARMA model.And the filter result is analyzed by frequency spectrum and Allan variance analyzing method,the results show that this method can effectively improve the accuracy of FOG.

基于非平稳时间序列模型的卡尔曼滤波可以减小陀螺在恒定温度下零漂，Allan方差和频谱分析法表明这是一种简单有效的提高陀螺精度的方法。

So the tension、velocity、 length and time, all these four variates are needed for description of myocardial constitutive properties. Up to now, it is not clear in the study of myocardial dynamics just mentioned above. Especially, some studies on myocardial dynamics are aimed at only two items of these fours, but others are not in a constant level. As a result, the study in different ways has poor comparibility, even contradicts each other.

故到目前为止，心肌力学的研究仍被这四个量之间的关系搞得含混不清，特别是许多研究只针对其中某两个量之间的关系进行研究，但并未将其余两个量固定在一恒定水平上，使不同研究之间的结论可比性较差，某些方面甚至互相矛盾。

They were all in SCOTT connection, and to avoid the academically foreseen instability problems ( due to decreasing melt resistance with increasing temperature ) every heating zones was equipped with power-constant regulation, as well as temperature control.

他们都是在斯科特方面，并应避免在学术上所预见的不稳定性的问题，（因降低熔体电阻随温度升高），每个采暖区配备了功率恒定的规管，以及温度控制。

Improve the accuracy of the evaluation of real experimental data from potentiometric titrations and consider samples ranging from vinegar, wine, and juices to humic acids and acid rain.
