还原的

So the classroom has to revivify and transcend to the life world so as to give the classroom vitality and energy.

当前课堂的问题在于悖离了生活世界，所以课堂必须还原与超越，才能焕发出生气和活力。

Particles may be seen to be of different sizes and shapes (oval, triangular, oblong, rhomboid, etc.).

当还原过程中结晶和聚集速度不能控制时，形状不规则的颗粒将会产生（见图4）。

It could use Vat Blue RSN as a nitrogen source, but not as a carbon source. The medium composing of saccharose and ammonium nitrate as carbon and nitrogen sources was decolorizing potential markedly during different combinations of carbon and nitrogen sources.

此外， 菌株Asaw117能利用还原蓝RSN作为氮源，但不能利用其为碳源；几种碳氮源组合实验中，菌株在蔗糖、硝酸铵组合的査氏培养基脱色效果为好。

Five kinds of bacteria were isolated from disease Meretrix meretrix and culture water (two isolated from the M. meretrix, three from the culture water) in Lvsi harbor, Jiangsu province. The results of infection showed that strain WG1702 can cause disease with the mortality rate 100 percent and the same symptoms as original. It was cued that strain WG1702 was the pathogenic bacteria and caused the death in large scare, a preliminary research was done on the bacteria including morphological, physiological, biochemical characteristics, phylogenetic position and pathogenic. Strain WG1702 was a straight-rod gram negative bacterium, the physiological and biochemical indicators were lysine decarboxylase, ornithine decarboxylase, reduction of NO3- to NO2-, mannitose, oxidase and methylred reaction positive, arginine decarboxylase, arginine dihydrolase, salicin and voges-proskauer negative.

本文从江苏吕泗文蛤养殖区发病文蛤和养殖水体中分离到5株优势菌(病蛤中分离到3株优势菌，养殖水体中分离到2株优势菌)，人工感染实验结果显示，菌株WG1702能引起供试文蛤发病，死亡率为100%，且发病症状与原发病症状相同，提示该菌是引起文蛤大面积死亡的主要致病菌，对其形态、生理生化特征、分类地位及致病性进行了初步研究，菌株WG1702为革兰氏阴性菌，直杆状，生理生化指标为：赖氨酸脱羧酶、鸟氨酸脱羧酶、硝酸盐还原、甘露糖、氧化酶、甲基红阳性，精氨酸脱羧酶、精氨酸双水解酶、水杨素、V.P阴性。

New metalized films were obtained by the reduction of PAN/metal salt chelate films with NaBH4 aqueous solution.

以硼氢化钠（NaBH4）水溶液还原聚丙烯腈／金属盐络合膜后，就可得到一种新的高分子表面金属化材料。

The organic geochemistry characteristics of source rocks and oil sands in Well Hu 41,Well Hu 83 in Huzhuangji area are studied,by which a preliminary judgement is made that the type of kerogen of Es_3 source rock is a mixed type with high maturity,and its depositional environment is saltness reduction one.

通过对胡状集地区胡41井、胡83井等烃源岩和油砂进行有机地球化学特征研究，可以初步判定胡状集地区沙三段烃源岩干酪根类型为混合型，成熟度较高，沉积环境为咸化的还原环境；沙三段原油属于成熟原油，沙二段原油属于低熟原油；沙三段原油为自生自储原油，沙二段原油与沙三段原油不同源。

6β-santonin could be selectively reduced and hydroxylated by the cell suspension cultures of P.acinosa, which would provide valuable intermediates for its further structural modification.

结论利用商陆培养细胞可对6β-santonin进行选择性还原及羟基化反应，可为其进一步化学结构改造提供有价值的中间体。

Several parameters of the voltammetric determination, such as the kind of electrolytes scan rate, pH value, were investigated.

利用伏安法、计时电量法及旋转圆盘电极法对其氧化还原过程进行研究，得出其的电子转移数均为2。

Upon binding Scap and reductase,Insigs exert actions that limit cholesterol synthesis.

Scap和HMG-CoA还原酶结合在Insig上使其构象发生变化，发挥作用限制胆固醇的合成。

SCEat mercury eleetrode and the two are irreversible.

SCE产生两个不可逆的还原峰。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
