We discuss a class of second order self-adjoint matrix differential systems with damping term and self-adjoint Hamiltonian matrix differential systems, etc.

在第五、六章中，考虑一类线性泛函g和一类对s偏导数不一定非正的Hk型函数，分别研究了自伴的带有阻尼项的二阶矩阵微分系统和自共轭的Hamilton矩阵微分系统。

The seed purity of more than one hundred and thirty samples of six maizevarieties was assayed by using the three testing methods: storage proteins electrophoresis,isozyme isoelectric focusing in acrylamide and examination at field plots. Some importantpoints can be concluded from analyses as spearman order rank correlation on the seedpurity data as follows:First, there were deviations of the real performances to those purities obtained from out or in laboratory testing, even from the examination at field plot that is a routine way. Second, the seed globulin and isozyme electrophoresis, both with characteristics of rapid, cost-effective, devoid of environmental effect and speed, showed consistent purity; while the field-testing gave a higher degree of purity on the high side of cost than that in-lab approaches. Third, a good consistent purity was observed in the field plot and seed globulin testing, whereas inconsistency between field-testing and isozyme process. The last point is that seed globulin electrophoresis be a practical method apt to seed purity testing for maize.

并对130多份样品用三种检验方法(盐溶蛋白电泳、同功酶等电聚焦电泳和田间小区)检测的种子纯度数据作排序相关等统计分析，得到如下结果：室内外检测方法都会与种子真实状况有一定差异，田间种植鉴定与真实情况符合性并不一定最好；盐溶蛋白与同功酶等电聚焦这两种方法检测种子纯度所需时间短，成本低，不受外界环境限制，出结果快，二者的结果没有太大差异；田间种植鉴定成本较高，检测的结果普遍偏高；等电聚焦电泳与田间鉴定的一致性年度间存在差异，而盐溶蛋白凝胶电泳法与田间鉴定的一致性较高；种子盐溶蛋白凝胶电泳法较适于鉴定玉米种子纯度。

I chose science because I wanted to break my uncle's opinion in high school, but due to bad vision, I was not the first place and still top students.

Cold places like cold stone substrate, transparency, quality nourish, low hardness, gloss strong line better varieties; soft ground nearly frozen to substrate, but the lack of transparency; just manner, then the hardness high, often with quartz quality of sand screw; hard the worst quality, hardness, opacity, gloss weak, often more impurities, and rock in the gravel. 3, defects, including impurities and cracks in the stone.

冻地的底质似冻石、透明度高、质细润、硬度低、光泽强，系较佳品种；软地的底质接近冻地，但透明度不足；刚地，则硬度偏高，常含石英质砂钉；硬地的品质最差、硬度大、不透明、光泽弱，常有较多杂质和围岩中的砂砾。3、瑕疵，包括石中的杂质和裂纹。

Results: Reliability coefficient of the four courses was above 0.6, and moreover 91.7% was above 0.7, but the difficulty and discrimination coefficient were not satisfied.

结果：各年级四门课程信度系数都达到了0.6分以上，且91.7%在0.7分以上，显示了较高的信度，但是难度普遍中等偏低，区分度不高。

That translated into off-kilter, asymmetrically draped pieces that seemed just right for the season: bias-cut skirts, slouchy pajama suits, scarf dresses, and unstructured cocktail numbers worn with scads of necklaces and embellished with a scattering of beads or sequin polka dots.

While not shown in CIRA-86, there is a clear easterly band extending from the equator to high latitudes at the altitude of lower thermosphere in autumn.

在冬季，东亚区域中间层西风急流中心位于25°N-35°N之间的75km高度，与CIRA-86相比，该中心纬度偏南5°，高度偏高10km；在秋季，东亚区域低热层高度存在一个显著的从赤道到高纬度的东风带，而CIRA-86不存在。

In the region, the winter mesospheric westerly jet lies at 75km altitude and in between 25°-35°N, which is 10km higher and 5°farther south in latitude that of the CIRA-86.

Speaking at Metal Bulletin's 13th bauxite and alumina conference in Athens, Shah said curtailments at refineries may follow, particularly at non-government-owned operations in China, because the lower prices will make plants uneconomical.

在雅典举行的金属导报第13届铝土矿和氧化铝会议上，Shah表示精炼厂仍将继续减少，特别是在中国非政府控股的工厂内，因为价格偏低将使工厂不太经济。

If a friend to see him, he would tell friends in the west gate, etc., in fact, from a sense of direction of view, that the so-called "Simon" is not the position of the root to the west, and in the northerly direction, but the residents live here have said the door for Simon, he has also called Simon.
