It can be predicted that the development of taekwondo in China has been in a favorable circumstances. On the other hand, we should realize that there are some problems and defects in the development of taekwondo. With the method of documentary compilement, logistics, interviews and mathematical statistics, this article make a detailed analysis on the roots,statement and problems of the taekwondo rapid development in China. Form two aspects of athletics taekwondo and mass taekwondo, the author makes the deep study and search for feasible countermeasures, proposals and theory basis for the healthy, orderly, sustainable and virtuous development of taekwondo in China.

Ca is widely abundant in nature and its rodioisotope 41 Ca is a cosmogenic nuclide with a half\|life of 10 5 years. However, the 41 Ca/ 40 Ca ratio in natural samples is very low and can only be measure d by accelerator mass spectrometry. The application of 41 Ca is ve ry i mportant not only in the life science but also in geological dating, global envi ronment change studies and astrophysics.

1 引言Ca在自然界中广泛存在，它不仅是人体中含量最丰富的元素之一[1] ，也是众多其他物质的组成部分。41Ca(半衰期为 1.0 3× 10 5a)属于Ca的放射性同位素中的一种，其衰变方式为轨道电子俘获，只发射3.3keV的X射线，天然样品中41Ca 40 Ca的值很小。

Software, and simulated by Monte Carlo method. The simulation results are conducted by descriptive statistics. Two "drop-in" assembly design lens groups were studied to calculate the stack-up element tilt and decenter within a cell and the resultant deviations of the optical axes away from the mechanical datum axis. The results indicate that the opto-mechanical tolerance model can analyze the critical to quality parameters of a lens system. As a result, the performance of the lens system can be anticipated by the opto-mechanical tolerance model before mass production.

戊n体编辑，并以蒙地卡罗方法模拟，模拟结果以叙述统计呈现；最后以两个&投入式&组立设计的镜群组为案例，计算镜片在镜筒内的累积偏心角度公差、偏心距离公差及镜片光学轴的累计偏移量，其结果显示该模型可模拟一个镜头系统的关键品质参数；所以，镜头系统的性能在大量生产之前可藉本光机公差模拟模型预测其品质与良率。

So it is of much significance to study the mechanisms of ovule development and abortion of Chi- nese pine. By combining two-dimensional gel electro- phoresis (2-DE) and mass spectrometry analysis, the pat- terns of gene expression in a specific tissue at a specific stage can be displayed and characterized.

双向电泳和质谱技术结合研究基因表达的蛋白质组技术正越来越广泛地应用到植物研究中，我们将该技术应用到油松胚珠发育的研究中，比较了两种蛋白质提取的方法，发现蔗糖提取方法比传统的TCA 方法更适合于油松蛋白质的制备。

It could be that the hydrothermic properties of this region produce hurricane-force ice storms that cause the ocean to freeze and then melt and then refreeze, resulting in a semisolid migrating land mass that would land a ship right around here.

呃，虽然我不是专家不过有可能是此区的地热现象引发飓风级的冰风暴让海洋冻结、融化又冻结，结果形成一块飘移的大陆船只是有可能会撞进来的

The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.

结果表明，所合成的化合物B的结构与预期的结构一致；热性能研究表明，化合物B在242.2~750℃质量损失为54.39%，1000℃时仍有25.11%的炭残渣，显示出优异的热稳定性和成炭性；在相同反应条件下，用乙腈作为溶剂的反应产率比使用氯仿和二氯乙烷为溶剂的高，并且在合成过程中，单独使用三乙胺作为缚酸剂时产率很低，而当同时加入少量4-二甲氨基吡啶时，产率可达81%。

The dynamic variation in content of cndogenous abscisic acid,indoleacetic acid,gibberellinsand isopentenyladenodines of normal juvenilefruit and dropped fruit was measured with enzyme linked immunosorbent assayin the course of physiological fruit drop of 'Shuizhang Longan.
