Last results showed that desiccation and priming could make the membrane structure to be preserved and restored. Many kinds of substances protect the membrane structure, such as soluble sugars, proteins, amphiphilic molecules, calcium ion, polyamine and other radical cleared system of nonenzyme katalyst, etc. These protective substances cooperate together to stabilize the structure of membrane lipids and proteins, and to keep the integrality of membrane structure, so the membrane function can exert normally and seed vigor can be improved.

研究表明，超干和引发处理可使膜结构得到保持与修复，很多种类的物质参与了膜结构的保护，例如可溶性糖、蛋白质、两性分子、Ca2+、多胺及其他非酶促自由基清除系统等，保护物质协同作用，稳定膜脂及膜蛋白的结构，保持膜系统的完整性，使膜功能得以正常发挥，强化了种子活力。

Methods The flavones were extracted by using ethanol as the solvent from Leonurus with ultrasonic wave and extraction method.A spectrophotometry was used to extract and check the flavones of Leonurus.The effect of Leonurus on scavenging of hydroxyl radicals was studied.

采用超声波乙醇浸提法从益母草中提取黄酮类物质，对所提取的黄酮类物质进行验证，并用分光光度法测定含量，用益母草总黄酮对羟自由基清除作用进行试验。

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

Based on their distinctive optical properties, a method of determining the specific rotation was set up to distinguish these two kinds of chemical materials in the standard for detection of levogyrate preparati.

二者的差别在于盐酸噻咪唑为外消旋体，盐酸左旋咪唑为左旋体，通过利用两种物质的光学特性，在盐酸左旋咪唑制剂的检测标准中设立比旋度测定方法，从而将两种不同的物质加以区

Kefir grains are Sticky granularmatters, consisting of protein, lipin and sticky polysaccharide.

开菲尔粒是一种黏性粒状的物质，由蛋白质、脂质和黏性多聚糖等物质组成。

The total flavone in antioxidant substance extracted from leaves of tartary buckwheat and its scaveninging function to OH and O(superscript - subscript 2) were determined by photometry and the inhibitory action to Lipin peroxidation and its synergy with other substances were studied by iodimetry in the experiment.

从苦荞叶中提取抗氧化性物质，用光度法测定提取物中总黄酮的含量及对羟自由基和超氧阴离子O(上标-下标 2的清除作用，并采用碘量法研究了苦荞叶提取物对脂质过氧化的抑制作用及与其他物质的协同作用。

Only in lower β situation (For example: the value of β at the equator of the sun's surface is 0.25 or less), can we reappear the typical shape of looplike CMEs: the legs of the looplike CMEs at the surface appear between the open and closed magnetic field, show little movement in the latitudinal direction; the initial change of the top material appears on both sides of the current sheet during its outward propagation, the relative variation of density at the top becomes less than both sides.

只有在β较小(如太阳表面赤道处β〓等于0.25)的冕旒背景下，才可重现典型类环状CMEs观测形态：足部出现在开场与闭场的交界面上，在纬向基本不动；CMEs顶部物质密度变化在传播过程中比两侧物质密度变化小。
