The contents of valine and leucine of the nematode are obvious higher than that of others in different kinds of amino acid of the nematode. The analysis of irritant factors playing a important role on the production of predacious organs showed that live nematode larva or its lytic solution can cause the production of predacious organs of the strain A1, but the latter produced less than the former .The live larva of the third stage produced more predacious organs than one of the first and the second stage , so the number of predacious organs that are produced by the live larva of first and the second the stage are less than the live larva of the third stage .

刺激捕食器产生的因素在线虫体来说：活的线虫幼虫和其裂解液可以刺激捕食线虫性真菌—少孢节丛孢菌菌株产生捕食线虫性结构——捕食器；但后者刺激产生的捕食器数量较少；有活力的第三期幼虫与第一、二期幼虫相比较，可以刺激菌株产生较多的捕食器；但少孢节丛孢菌对第一、二期幼虫作用速度快；与第三期幼虫相比，第一、二期幼虫易被捕获致死。

These results demonstrated that estrogen deficiency after ovariectomy increased in bone resorbing activity present in bon marrow supernatants and it were mediated partially by endogeneous IL6, Suppression for IL-6 production were involvement in the mechanism of estrogen replacement therapy inhibiting bone loss in estrogen deficiency.

这些结果提示，卵巢切除导致内源性骨吸收因子IL-6产生增加，并且IL-6在骨吸收增加中起着关键作用，雌激素抗骨吸收作用部分是通过降低IL-6产生而介导的。

Rabbits were equipped with intracerebral cannulae directing to two of the four nuclei.

我们在研究吗啡的中枢作用部位时发现，注射微量吗啡到家兔或大鼠的PAG、伏核、杏仁核或缰核内，可产生明显的镇痛作用；而将阿片受体阻断剂纳洛酮注入上述任一核团内，则能大部取消静脉注射吗啡产生的镇痛或电针引起的镇痛。

The experiment results show that the vibration may accelerate abrasion and aggravate the localized corrosion due to the fact of non-homogeneous distribution of corrosives and debris created in above process.

结果显示，单纯的压力作用不会对碳钢产生严重腐蚀，但振动作用能加速磨损腐蚀，磨屑及腐蚀产物的堆集，造成这一区域的不均匀分布，从而产生严重的局部腐蚀。

The theory is that electron launched by electron gun is inducted into discharge chamber with screen voltage attracting, gas will be charged by inputting RF power. Ion can be attracted by screen and accerlate voltage.

射频宽束离子源工作原理是利用电子发生器产生电子，在屏极电压作用下把电子引入离化室，利用射频感应原理将能量耦合到离化室，再利用气体放电原理产生等离子体，在屏极和加速极的作用下引出离子束。

Two outstanding fusants SR-7 and SR-T19 were chose out in the fusion group 90-11×FR-008, the former produces not only antibiotics the parents produced but also a new antibiotic effective gainst a wide range of both gram positive and negative bacteria, which the parents could not produce, and its product of the 37℃ fermentation was very effective against the cotton seedling damping off caused by Rhizoctonia sonali while product of the 26℃ was effective agaist the bacterial rots of turnip and Chinese cabbage; the latter have a much stronger activity against a wide range of fungi and yeasts than the parents.

在90-11×FR-008融合组合中，筛选获得2个优良融合子SR-7和SR-T19，前者除产生亲本产生的抗生素外，还产生亲本不产生的一种新的具有广谱抗细菌活性的碱性水溶性抗生素，防病试验表明，其37℃发酵产物对棉花苗期立枯病具有良好的防治效果，28℃发酵产物对萝卜和大白菜具有明显的防腐作用；后者与亲本FR-008的抗菌谱完全一致，但其活性强度都超过了FR-008；采用RAPD分子标记技术检测了SR-7和SR-T19与亲本的同源性及彼此间的差异，从而首次直接从DNA分子水平上验证了链霉菌的原生质体融合子及其遗传重组的多样性。

了解乙酰胆碱直接产生的M、N样作用、抗胆碱酯酶药间接产生M、N样作用方式。

The results show that the growth rate of tetrapod ZnO is controlled by spiral growth and its crystallization is via VLS model. The condensation of tiny zinc droplets in zinc vapor is the key factor of the formation of tetrapod ZnO. The growth steps are formed on the terminated faces as zinc diffuses outwards and the elongation of whiskers continues until zinc inside the droplets is depleted. VS crystallization, which has little effect on the elongation growth, takes place on side faces of the whiskers and consequently makes the whiskers radius increase.

结果表明： T-ZnO晶须的结晶作用是气-液-固方式，晶须生长受螺旋生长机理控制；锌蒸气中产生凝聚生长的锌液滴是制备T-ZnO晶须的关键，锌从液滴内向外扩散在晶须的端面产生生长台阶，随着液滴内的原子向外不断扩散，针体部分就不断地伸长生长，当液滴内的原子全部消耗尽时，晶须便不再发生轴向生长；气-固方式的作用主要是促进晶须棱面生长而使晶须变粗，对轴向生长几乎没有影响。
