查询词典 envelope environment

The Hilbert amplitude envelope of the stator current includes the low frequency of fault characteristic, thus it can reduce the signal length by resample the Hilbert amplitude envelope of the stator current by downsampling, which can avoid spectrum aliasing. Then it can reduce the computation time of the MUSIC Method for the spectrum analysis to the resampled signals for the given bandwidth. Meanwhile combining continuous subdivision Fourier transform and rotor slot harmonics based slip estimation it can in advance estimate the concrete values of the fault characteristic frequency, and then inquiry purposely the fault feature component information in the stator current spectrum in order to accomplish the broken rotor bar fault with high sensitivity and h reliability, which eliminates adverse effect of issuable false peaks to the fault detection and formed a novel scheme to detect broken rotor bar fault.

定子电流Hilbert幅值包络信号包含了低频的故障特征频率调制信号，故通过对定子电流Hilbert幅值包络信号进行降采样率重采样、减少分析信号长度，可避免低频段频谱混叠，再对减少的重采样数据进行具有超分辨率的MUSIC低频段估计，可大大降低MUSIC算法频谱估计时间；运用连续细化傅里叶变换和转子齿槽谐波转差率估计技术，可预知故障特征频率精确值，从而可有目的地查询故障分量，消除MUSIC虚假波峰对故障检测混淆的影响，大大提高了故障检测的灵敏度和可靠性，以此形成异步电动机转子断条故障检测新方法。

When the embryo reached the prehatching stage, the hatching enzyme granules were secreted into the perivitelline space from the top of HGCs. Secretory granules were spherical and 0.5-1.0 μm in diameter. The hatching enzyme was dissolved in the perivitelline fluid, where it gained access to the egg envelope and digested the inner layer of the egg envelope.

至孵化前期时，孵化酶颗粒自HGCs顶部的开口分泌出来，分泌颗粒呈圆球形，直径为0.5-1.0 μm，有的以单体的形式存在，有的粘结成团。

The envelope contains a vent to permit ingress and egress of air from the pillow or cushion (3). The envelope also includes a sealable opening to permit insertion and removal of the pillow or cushion.

该封套有能让空气进出的通风装置，和一个能让枕头放入和取出的可密封的开口。

For this purpose, we have placed a Remembrance Book in the church lobby so you may write down the names of those who have gone before us on the special envelope. Put the envelope together with your offering inside the donation box.

各位主内的兄弟姊妹，让我们在主的圣殿内常表现出庄严、神圣的态度，留给自己和他人神圣、安静的祈祷空间，在圣堂内常保持宁静及个人收敛之心，特别常记著在耶稣前表达我们对祂的敬爱，好好的、礼貌地行个跪拜礼、或鞠躬礼。

Applying humidity controlling materials on the inner surface of building envelope, as a modern, energy-saving and environmental friendly method of controlling humidity, can effectively prevent building envelope from dewing. It can also control indoor humidity.

应用于建筑围护结构内表面的调湿材料作为一种新型的、节能环保的调湿手段，能有效的防止建筑围护结构结露现象，并起到调控室内湿度的作用。

There are two ways to produce nuclear vacuoles. One is that the outer membrane of the nuclear envelope distends towards the cytoplasm to form nuclear vacuoles; and the other is the double-layered nuclear envelope derives vacuoles by depressing inwards.

核膜囊泡有两种发生方式：1核膜的外膜向细胞质一侧膨胀产生囊泡，囊泡进入细胞质；2核膜向核内凹陷形成囊泡，囊泡进入细胞核。
