A fairly good correlation was found between the Simpson′ s rule method and the biplane area-length method (56±5%) or the two single-plane area-length methods, one using apical four-chamber (55±6%) and the other using apical right cardiac two-chamber view (57±5%).

双平面面积-长度法(56±5％)和心尖四腔观(55±6％)或心尖右心两腔观(57±5％)单平面面积-长度法均与Simpson法有较好相关，其中双平面方法优于单平面法。

In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。

Thus we extend the works by Fan and Humphreys independently on polycyclicgroups.In section 3,we prove that 〓 if G is a solvable non-torsion group ofrank 3.This extends a result of McCutcheon who proved it only for polycyclicgroups.

在第3节里，我们讨论了秩3的可解群，证明了当这类群含有无限阶元时，其导出长度至多为6，但在挠群的场合，其导出长度是不能界定的，这推广了McCutcheon的一个结果。

Because wreath tablet the hair feather of the yarn appearance with spin cotton serial number, yarn Nian degree, thin spindles soon, the involution take shape all of etc.s to spin cotton craft parameter to have direct influence, in the meantime because of wreath tablet the hair feather of the yarn appearance have no rule, at yarn surface of distribute and present random, even each segment of yarn length of same yarn size reflection of the hair feather be average value, the hair feather of various length value usually difference also big.

由于环锭纱线的毛羽状态与纺纱号数、纱线捻度、细纱锭速、卷绕成形大小等纺纱工艺参数有直接影响，同时由于环锭纱线的毛羽形态无规则性，在纱线表面的分布呈随机性，即使同一纱线大小纱各段长度反映的毛羽平均值，各种长度的毛羽值往往差异也大。

The method of the invention comprises the steps as follows: step 1: each frame of image is divided into N areas according to the sequence of coding and the bit flow length of each area after coding is recorded; step 2: according to the comparison result between the bit flow length of the coded area and a prearranged gate limit, the number of non-zero DCT coefficients of non-coded areas allowed in the coding process is adjusted.

本发明提供一种码率控制方法及控制装置，方法包括：步骤一、对于每帧图象，都按照编码的先后顺序划分为N个区域，并记录每个区域编码后的码流长度；步骤二、根据已编码区域的码流长度与预定门限的比较结果，来调整未编码区域在编码过程中所允许的非零DCT系数的个数。

With extension of the stolon , changes of the internode length , branching intensity and ramet length were fit to exponential model .

分株长度、间隔物长度和分枝强度随匍匐茎延伸呈指数模型变化，其克隆构型兼有"游击"型和"密集"型的特点，能比较"灵活"的适应环境。

In this investigation, the number of maternal ramets and daughter ramets, length of stolon and spacer, distributed pattern of spacer and the relationship with community quantitative character were compared and researched between the two Potentilla. This offers basic data for more discussions to ecological and phenotypic adaptive strategy of the two population.

本文就两种委陵菜种群的母株、分株数量、匍匐茎长度以及间隔子长度及其布局及其与群落数量特征的关系进行比较研究，为进一步深入探讨这两种委陵菜种群的表型适应与生态适应策略提供基础性研究数据。

To ensure accuracy of measurement, the CSM-91 should be located at least five pipe diameters down stream from any fitting and at least ten pipe diameters downstream from a pump.

为了保证测量的准确性，系列CSM-91应该放置在距离任何连接件下游至少五倍管道直径长度的地方，和泵下游至少十倍管道直径长度的地方。

Results in those 30 samples, the styloid process showed with high quality inⅠgroup is 25,in Ⅱ group is 27,about length measurement, as a whole, the difference of the two groups is little.

结果 30例中茎突能清晰完整显示的常规茎突侧位有25例，而用口腔全景机拍摄的茎突有27例，在茎突长度测量方面，从两种摄影方法拍摄的茎突影像上测得的茎突长度无显著的统计学差异。

The results show that the MDFA results almost do not depend on length of subseries, and ApEn could identify dynamic structure to some extent but still depend on the lengths of subseries. At the same time, there exists a huge drift for the ApEn results which means the actual time-instants of abrupt change don't overlap with the detected one.

结果表明，新方法的检测结果几乎不依赖于子序列的长度，而ApEn虽然能在一定程度上识别系统的动力学结构突变区间，但其检测结果依赖于子序列长度，且不能准确地检测出突变点的位置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
