查询词典 parity

Both LDPC codes and OFDM technology are studied in this paper. The working and the results obtained are summarized as follow:1. The definition of LDPC codes and its coding/decoding ideas are systematically summarized, a general algorithm of changing any parity-check matrix to lower triangular form, which is suitable for quick encoding, is given out, along with a girth checking algorithm. Absolutely random LDPC codes construction is improved, a new half random construction of LDPC codes with linear time coding and no 4-cycles is brought out.

系统地阐述了低密度校验码的定义及编译码原理，提出了一种将任何校验矩阵变换成适于快速编码的近似下三角形式的通用算法及一种围长检测算法，对完全随机的校验矩阵构造法进行了改进，提出了一类消除4环且可近似线性编码的校验矩阵半随机构造法，仿真表明，在高编码效率情况下，改进后的半随机构造法，其性能稍优于完全随机构造法，并可以线性时间编码，因此更适合实际应用。

The read and write methods make no assumption about type and format of data send or received, you must take into account if you are handling a character or binary format, if there is Unicode, mbcs, etc. The open function if defined as follows:virtual BOOL OpenLPCTSTR PortName, DWORD BaudRate, BYTE ByteSize, BYTE Parity, BYTE StopBits

读写方法，不作任何类型和对数据格式发送或接收，你必须考虑到，如果你正在处理一个字符或二进制格式的假设，如果是Unicode，的MBCS等功能的开放，如果定义如下："/页"虚拟布尔公开赛（LPCTSTR端口名，双字节值波特率，字节ByteSize，字节校验，字节停止位

We further analyzed the interaction of age, menarche age, and parity.

患者年龄及产次对罹患宫颈癌的影响？

Grid parity (where solar costs the same per kilowatt hour as conventional electricity) is a term often used in green energy circles, most often in the form of misty-eyed dreaming. Suddenly, it's just over the horizon five years in some European markets, say experts.

电网平价（在相同的太阳能电池的成本每千瓦小时常规电力）一词经常以最频繁的形式出现在绿色能源界，专家指出，突然间，它只是五年来在一些欧洲市场地平线。

Since ρ〓,ω are neutral vector mesons, the G-parity breaking is caused by the isospin symmetry breaking. We study the form factor of π, F〓, which is an important observable related to ρ〓-ω mixing problem.

在这个问题中，由于ρ〓，ω都是中性矢量介子，因此G宇称的破坏主要是由同位旋对称性破缺引起，在讨论这个问题时我们首先讨论了对ρ〓-ω问题有重要意义的π介子的电磁形状因子F〓。

Sixty multiparity(parity 2or3),healthy dairy cows,which had the adjacent milk yield and body weight,and at 40-50 mean days in preterm.

选取泌乳量、体重差异不显著，胎次2-3胎，平均在预产期前40-50天，且健康无疾病的经产奶牛60头。

An interview guide entitled,"Maternal Perception of the Onset of Lactation" was also used to obtain milk secretion data. The analytical results revealed a mean onset of lactation of 75.7±16.8 hours (range=40 to 117). The prevalence of delayed lactation onset was 50.5%(n=58); 64.3%(n=42) were primiparous, and 41.9%(n=74) were multiparous. Parity, hours of withholding oral intake post-operation, and use of formula were significant predictors of perceived lactation onset. These factors explained 22.5% of perceived lactation onset in postpartum women who planned cesarean section.

研究结果发现：(1)泌乳起始时间的平均值为757±168小时（范围40至117小时）；(2)产妇自觉延迟泌乳的发生机率为500%(n=58)，其中延迟泌乳的初产妇有27位，占所有初产妇(n=42)的64.3%，延迟泌乳的经产妇有31位，占所有经产妇(n=74)的41.9%，经产妇发生延迟泌乳的机率较低；(3)产次、术后禁食时间以及配方乳使用，是泌乳起始时间的重要预测因子，共可解释计画剖腹产妇泌乳起始时间总变异数的22.5%。

Eight healthy multiparous Chinese Holstein cows in early lactation were chosen. There were four high-yielding cows and four middle-yielding cows, separately with similar milk yield, parity and parturition date and body weight.

选择8头经产泌乳早期的中国荷斯坦奶牛，其中4头中产奶牛和4头高产奶牛(健康无病，中产奶牛和高产奶牛分别具有相近的产奶量、胎次、产犊日期和体重)，分别采用4×4拉丁方试验设计进行试验，研究日粮中补充染料木黄酮对奶牛的影响。

Eight multiparous Holstein cows in mid lactation were blocked by milk yield (24.3 ± 2.9 )kg/d, parity (3.4±1.1), days in milk (148.5±14)d, similar body weight and heredity composing into two groups of four and randomly assigned to 4 X 4 Latin Square trial with four periods.

本试验选用泌乳中期经产荷斯坦奶牛8头，平均产奶量(24.3±2.9)kg╱d，胎次(3.4±1.1)胎，泌乳天数(148.5±14.0)d，体重无显著性差异，遗传组成基本相似，健康无疾病。
