查询词典 sub zero

If len is non-zero then *m is filled in with what matched the regular expression, m[0] contains what matched the whole string, m[1] the first sub-expression etc, see regmatch_t in the header file declaration for more details.

如果 len 不是 0，那么*m 被填充为正则表达式匹配的结果， m[0] 包含整个字符串匹配的结果， m[1] 是第一个子表达式匹配的结果，依此类推，更多细节参见 regmatch_t 在头文件中的声明。

This paper studies the properities of weakly invertible Linear finite automata through zero state,and obtains some results of weakly invertibility of Linear finite automata and description of the minimal linear finite sub-automata.

通过零状态研究了线性有限自动机的一些性质，得到了线性有限自动机弱可逆的一些结果，并给出了最小线性子有限自动机的描述，最后给出了算法实现。

To solve the second problem, an approach of irregular QC LDFC codes is proposed. The proposed approach is to replace some sub-matrices by zero matrices and identity matrices at special positions in the given sparse parity-check matrix so as to get a nonsingular square matrix for the construction of the generator matrix.

为解决第二个问题，提出一种不规则准循环LDPC码的设计方法，该方法将校验矩阵中的特定位置的子矩阵用零矩阵和循环矩阵置换，获得一非奇异方阵，用于构造生成矩阵。

In this paper, an algorithm to achieve both two dimensional high resolution and wide swath is proposed. Every small satellite work in the active state, they transmit and receive different frequency band signal simultaneity. First, the azimuth ambiguity is eliminated in each frequency sub-band, then the signal is rectified to zero Doppler frequency, after that this algorithm does the range spectral synthesis to achieve high range resolution.

该文分析了一种沿航向排列分布式小卫星宽测绘带二维高分辨率成像技术，每颗卫星同时发射接收不同频率的线性调频信号，先分别在每个子带解方位多普勒模糊，并将方位多普勒中心频率调整至零频，然后在距离向进行子带拼接得到大带宽的线性调频信号从而得到高的距离向分辨率。

Base class sub-objects may have zero size. an object of podi type (3.9) shall occupy contiguous bytes of storage.

基类子对象可以具有零大小。podi类型（3.9）的对象总是占用连续的字节存储。

After this,it is examined whether there is zero point in each sub-interval vector.

然后， 采用区间二分法对给定的区间矢量进行二分并判断每个区间是否有解。

In order to eliminate the aliasing, at each step of decomposition or reconstruction, fast Fourier transform is performed the result obtained by convolving the input signal with filters, setting frequency spectrum of the redunctant frequency components to be zero, and inversely fast Fourier transforms the result after zeroing. The result after processing is the input signal of next step,and single sub-band reconstruction is implemented to extract the feature item of GPS data sequence.

为消除频率混淆现象，分解与重构时，每作一次信号与小波卷积后，将其结果作一次快速傅立叶变换，频谱中多余的频率成分的谱值置零，再对置零后的频谱进行傅立叶逆变换，然后继续进行小波包的分解与重构，从而实现单子带重构提取GPS数据序列特征项。

大意是：为了帮助克林贡人在长途跋涉中确保电脑的安全，杀毒软件公司 Sophos 推出了一款克林贡语版的杀毒软件，并于近日开始可供免费下载使用。

To address this situation, I believe that the operation could be improved on are: the installation and adjustment of measuring, the first sub-scale do to adjust the nominal cylinder liner size, and then dial indicator card installed and well well inserted under the initial installation of the traffic card directly into the cylinder table by measuring the smallest cylinder liner wear, the cylinder table adjust the volume of the extended length of rod inserted, so that the volume of the dial indicator cylinder table has small hands around 1.5-2.0 preloading cell volume and cylinder volume table mother under lock locking plug, the final table and then measured the volume of cylinder rod and rod card inserted at the anvil micrometer measuring bar between the seat and the large dial and adjust the dial indicator to zero.

针对这种情况，笔者认为，操作上可改进为：安装和调整量具时，先将干分尺调整到气缸套的公称尺寸，再将卡装好百分表和初步安装好插杆的量缸表直接卡入所测气缸套磨损最小处，调整量缸表插杆的伸出长度，使量缸表的百分表小表针有1.5-2.0格左右的预压量并将量缸表的插杆锁母锁紧，最后再将量缸表的测杆和插杆卡在千分尺的砧座和测杆之间并将百分表的大表盘调整到零。

Engine cylinder liner of the general process of measurement are: cylinder liner according to the nominal size measuring selection, that is, sub-thousand-foot-cylinder form and quantity (including the volume of cylinder rod inserted table); installation and adjustment of measuring, that is first to adjust micrometer cylinder liner the nominal size, and then loaded card good indicator of the volume of cylinder form measuring bar and the bar card inserted in the anvil micrometer measuring bar between the seat and adjust the volume of cylinder form of extended length of rod inserted, when the dial indicator of the 1.5-2.0 cells have small hands around the amount of pre-press under lock-lock female plug, and a large dial indicator to zero adjust

发动机气缸套测量的一般过程是：根据气缸套的公称尺寸选择量具，即千分尺和量缸表；安装和调整量具，即先将千分尺调整到气缸套的公称尺寸，再将卡装好百分表的量缸表的测杆和插杆卡在千分尺的砧座和测杆之间，调整量缸表插杆的伸出长度，当百分表的小表针有1.5-2.0格左右的预压量时锁紧插杆锁母，并将百分表的大表盘调整到零
