The effect of nitrogen and potassium fertilizers on nutrient quality of two lettuees were different, increasing potassium or nitrogenous fertilizer was more effective in acid soil than in alkali one.

不同施肥处理对两种土壤上科兴3号和双尖莴笋营养品质的作用不一致。在酸性土壤上增施K肥或提高N肥的用量对莴笋营养品质的改善更有效果。

And I was so pleasantly musing over the two men mowing: the young one, with long legs in bright blue cotton trousers, and with bare black head, swinging so lightly downhill, and the other, in black trousers, rather stout in front , and wearing a new straw hat of the boater variety, coming rather stiffly after, crunching the end of his stroke with a certain violent effort.

Characteristics of these two kinds of spinels not only indicate that the whole terrain underwent granulite facies metamorphism but also provide direct mineralogical evidence for the argument that Yushugou ophiolite suite of granulite facies lies in an environment of oceanic basin.

这两类尖晶石的特征一方面说明该地体遭受了麻粒岩相的变质作用改造，另一方面也提供了榆树沟麻粒岩相蛇绿岩套属洋盆构造环境的直接矿物学证据。

The world's most famous two spinels are part of the British Crown Jewels, but these beautiful red gems are traveling under an assumed name.

When pulp chamber access were achieved, the working length of each canal was measured using ROOT ZX apex locator with root canals in dry or moisture conditions.

常规根管清理后，采用ROOT ZX根管长度电测仪在干、湿两种根管状态下进行根尖位置的探测，根管充填后，根据X线片影像确定根管长度电测法的准确性。

Methods 96teeth with pulpitis or periapical periodontitis were instrumented by handling ProTaper rotary instruments using step-down technique,and by K files using step-back technique for control.All teeth were obturated with lateral condensation methods.The efficiency of preparation was analyzed with ra-diographs before and after operation.

选取患有牙髓炎和根尖周炎的后牙96例，随机分成试验组和对照组各48例，试验组用手用ProTaper多锥度镍钛旋转器械逐步伸入法预备根管，对照组用K锉，逐步后退法预备根管，两组均用侧向加压充填法充填根管，根据治疗前后的X线片，评价后牙根管预备效果。

结果：两组自体牙-下颌骨复合组织块移植后愈合过程相似；再生的牙周膜将牙根维持在原来的位置上，牙根尖发生轻微吸收。
