查询词典 efficiency engineer

The existing stone cutting tool, the tool bit is constituted by the sole grade's grinding material, when cutting the rough stone, the cutting speed is quick, the cutting efficiency is high, but the cutting surface fluctuates in a big way, becomes rough, after the cutting, grind and polishing take long time to do, if use the fine grinding compound, the cutting face is smooth, but the cutting speed is slow, the cutting efficiency is low, therefore the existing stone material cutting tool cannot have the high efficiency to cut the stone which have the smooth cutting surface, in view of this, how to keep the high working efficiency and get smooth cutting surface?

现有石材切具刀头由单一粒级的磨料构成，使用粗料时，切割速度快，切割效率高，但切割面起伏大，变得粗糙，切割后研磨抛光耗费时间长，使用细磨料，切割面较平整，但切割速度慢，切割效率低，因此现有石材切具不能高效率地切割出平整的石材，针对这一现状，如何既能高效率切割，又能使切割面保持平整呢？

The teaching efficiency is divided into two aspects,namely common teachintg efficiency and individual teaching efficiency according to Bandura's self efficiency theory.

根据班杜拉的自我效能理论，教师的教学效能感可以分为一般教学效能感和个人教学效能感两个方面。

The radiation by non-thermal plasma can accelerate formaldehyde thansform and make an increase of 29.61% in depurated efficiency. The surface modification makes no obvious difference in depurated efficiency. The chemical modification avails formaldehyde reduction and ACF coated with nano- TiO2 is the best of all that can enhand the depurated efficiency to 94%. The great influence of parameters on depurated efficiency , such as applied voltage and reaction time , shows that an increase in either applied voltage or reaction time enhance formaldehyde conversion.

研究结果表明：低温等离子体辐射能促进甲醛净化，可使其净化效率提高29.61%；表面改性对净化效率没有明显影响；化学改性有利于甲醛净化，其中负载纳米TiO2改性方案最佳，其净化效率高达94%；电源电压和反应时间等参数对净化效率也有较大影响，电压越大，时间越长就越有利于甲醛的去除。

Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.

在磷胁迫[0mmol/L，砂培]条件下，对不同基因型大豆苗期在根系形态、生物量等方面的差异进行了研究，结果表明：磷高效基因型在两叶期并未发挥出其基因型潜力的优势；四叶期，磷高效基因型的侧根数、侧根长、根系吸收面积、茎叶干重等性状的受抑制程度均显著低于磷中、低效基因型，而地下干重、根冠比却受到了较中、低效基因型更强的诱导作用。

Considering the characteristics of university sports,the article re-edited the questionnaire of self-efficiency,teaching efficiency of physical education teacher,in order to study the relationship between self-efficiency and teaching efficiency of physical education teacher in university.

教师教学效能感在理论上来源于班杜拉的自我效能感理论。

The transient transfection efficiency was measured by flow cytometry. The stable transfected cells were screened by G418. Results Electrotransfection had the highest transient transfection efficiency (56.8%), with the most masc clones of stably transfection and the least time taken to form big masc clones (20 days). Cationic polymer mediated transient transfection had the lowest efficiency (1.7%), with the least masc clones and the longest time taken to form the big masc clones (30 days). Cationic liposome transfection had a transient transfection efficiency of 39.9% and took 25 days to form the big masc clones.

结果 电转染有最高的瞬时转染效率(56.8%)，稳定转染得到的阳性克隆最多，且从细胞筛选到扩增至得到阳性大克隆所用的时间也最少（约20d）；用阳离子聚合物瞬时转染率低(1.7%)，稳定筛选同样可以得到阳性大克隆，但是数量很少且从细胞筛选到扩增至阳性大克隆所用的时间也最多（约30d）；阳离子脂质体转染效果居中，瞬时转染率为39.9%，从细胞筛选到扩增至得到阳性大克隆所用的时间约25d。

The goals (Satter and Thakur, 1994) of modern system-engineer's approach to hydrocarbon reservoir management are: managing efficiency; adequate time decision making; increasing oil and gas reserves and recovery; production increment; risk reduction; investment efficiency; minimizing costs and environmental protection.

现代系统-工程师的目标(1994Satter和Thakur接近向烃水库管理公亩：管理效率；适当时间决策；增加石油和气体预备队和恢复；生产增加；风险减少；投资效率；把成本和环境保护减到最低限度。
