Between 1930 and 1950, Louis de Broglie's work has been chiefly devoted to the study of the various extensions of wave mechanics: Dirac's electron theory, the new theory of light, the general theory of spin particles, applications of wave mechanics to nuclear physics, etc.

Results: The evaluation at the middle of period of treatment: the variations of pulmonary rales, perpheral bloody white blood cells and the X-ray examination an chest of the two groups' patients wren similar, but the symptom of fever and character of respiratory tract's secretion of the patients in experiment group took turns for better obviously than the control group's, the rate of elimination for ineffective on 3 day of the experiment group was obviously lower than the matched control. The evaluation at the end of period of treatment: the total effectualness and elimination of bacterium of the experiment group were notably higher than the matched control, There were not any obvious untoward reaction.

结果 疗程中期，两组肺部啰音、外周血白细胞及胸部X线检查变化相近，试验组发热、呼吸道分泌物性状较对照组明显减轻，3d无效淘汰率低于对照组；疗程结束，试验组有效率和细菌消除率均高于对照组，且未见明显不良反应。

To all fertilization treatments, the accumulation process of dry matter could be well fitted in the exponential equation y=aeb/x. Moreover, with fertilization amount rising, the a's value raised and b's remained stable.

In other Now the galax y ies is full of gas and dust, which could hide a distant supernova optically, but the remnant which would still produce s detectable radio wave s and X-rays.

如今的星系充满了气体和粉尘，这会从视觉上掩盖遥远的超新星，但超新星残骸仍会产生可检测到的射电电波和 X 射线。

The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。
