Convergence of semi-iterative method was discussed by Varga, Young and HU Jia-gan when iterative matrix is symmetric. In this paper, using Chebyshev polynomial and its properties, we obtain the convergence of semi-iterative method for a class of antisymmetric iterative matrix.

本文依据Varga， Young，胡家赣书中介绍的迭代矩阵为对称阵时，半迭代法的收敛性的理论，以Chebyshev多项式及其基本性质作为基本工具，对一类反对称迭代矩阵，研究其半迭代法的收敛情况。

Here's how to calculate your basic half turn. Let's say that you stand with your leading toe nine feet from the target when throwing a half turn. Now subtract the length of your arm at full stretch during the throwing motion, that is, at the point where the knife is released.

下面是测量半周投掷距离的方法：假定你在前脚脚尖距离靶子9英尺远的距离上成功地进行半周投掷，那么减去手臂在投掷动作中完全伸展时的长度，在此点上飞刀被释放。

It was illuminated that the width of the centre bright fringe decreased along with the increasing width of the rectangular aperture when the effect of the aperture on the beam couldn't be ignored,however,the width of centre bright fringe step changed with increase of the size of the aperture when the effect could be ignorable,the width of the half maximum intensity of the centre bright fringe decreased along with the accretion of the width of the aperture and then it tends to a constant.

结果表明，当光阑对光束的衍射影响明显时，光束衍射场的中央亮条纹的宽度随着光阑边长的增大而减小；当光阑对光束的衍射影响极小时，中央亮条纹的宽度随着光阑边长的增加而阶跃变化，中央亮条纹强度的半最大值宽度随着光阑边长的增大而减小；当光阑对光束衍射影响极小时，中央亮条纹半最大值宽度趋近于一定值。

In the high-frequency full-power, long tube output should pay special attention to the cooling system is normal, because the full power output of the tube heating than half-power when the high heat four times, when the cooling system abnormalities and easily damaged when the tube

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先，我们通过对20个科，38属，47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现，当水分胁迫强烈时，分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落，相反，湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势，也就是说，生境恶劣的植物种子在较强的干旱胁迫下，仍然保持了较高较快的萌发率及吸水率，水分充足与水分缺乏时无显著差异，而生境相对较好的植物种子在水分充足情况下萌发与吸水良好，但在干旱胁迫时则受到明显抑制，水分充足与水分缺乏时差异显著。

My baby was 2 weeks premature Caesarean section birth, insufficient breast milk, a month-An artificial feeding infant formula, has been eating better, although not a lot of food, but feed feeding table on the small standard deviation. 3 months have been all-you-can-per-150ML (a daily 5 times), but from 100 days to go to work I started on the point of death, my mother fed her the first time when the spit after eating 160ml, From then on, she ate 1 milk cried, but also fewer, and sometimes even a day 600ml are not, I work to feed her a little better, so that lasted about 10 days, my mother fed her不哭, and a 150ML, half an hour or so, I and she was dying husband to feed, each drink 60ml always to哭一场, tired of crying sleep eat eat 100ML, before and after one hour, the key is always eaten吐奶, four hours after the infants When she was always not interested, do not care to eat do not eat at all, thought it was tired of the beginning of milk, or poor appetite, but now has lasted more than a month, or about 700ml a day, nothing else very good, playing love laugh, urine are normal, sleep, or how to do?

我的孩子是早产2周剖腹出生，母乳不足，1个月开始人工喂养安婴儿奶粉，一直吃的还好，虽然吃的不是很多，但和喂哺表上的标准差的不多。3个月时已经吃到每次150ML(每日5次)，可是从100天后我上班开始就不行了，我母亲给她喂第一次时160ML吃完后吐了，从此以后，她一吃奶就哭，而且量也少多了，有时一天连600ML都没有，我下班喂她稍微能好些，这样持续了十天左右，我母亲喂她不哭了，一次150ML，半小时左右，我和老公喂她却不行了，每次喝到60ML时总要哭一场，哭累了睡着吃再吃100ML，前后要一小时，关键是这样吃完总是吐奶，四小时后该吃奶时她总是没兴趣，一点都不在意吃不吃，开始以为是厌奶，或是胃口不好，可现在已经持续一个多月了，还是一天700ML左右，其他什么都很好，爱玩爱笑，大小便都正常，睡觉也好，怎么办？

Here the proper occasions are these: the last month and a half of the hot season, the first month of the rains, these two and a half months being a time of heat, a time of fever; a time of illness; a time of work; a time of going on a journey; a time of wind or rain.

The results showed: the content of dissoluble substance, pectin, hemicellulose, lignin and cellulose in straw is 16.57%, 7.82%, 19.4%, 18.4% and 21.01%, respectively; the decrease rates of pectin, hemicellulose and lignin in retied stems are 82.10%, 17.01% and 11.40%, respectively; the content of dissoluble substance in flax stems has dropped rapidly from 16.57% to 7.93% in the first two hours of fermentation; the increase rates of bacteria number in the second two hours is 588%, which is the biggest in this process; the content of pectin, hemicellulose and lignin in flax stems will be declining with the retting going on.

结果表明，亚麻原茎中水溶物、果胶、半纤维素、木质素和纤维素含量分别为：16.57%、7.82%、19.4%、18.4%和21.01%；脱胶完成时，果胶、半纤维素和木质素脱除率分别为82.1%、17.0%和11.4%；在接种后发酵2h内，亚麻麻茎中的水溶物由16.57%迅速降至7.93%；接种后发酵2h- 4h，脱胶菌活菌量的增加幅度最大，为5.88倍；麻茎中果胶、半纤维素和木质素的含量均随着时间的延长而降低。

The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。
