结果表明:采用纯接种技术,在发酵前期可有效降低亚硝酸盐的含量,其中以接种肠膜明串珠菌效果最佳;同时在发酵过程中添加适量蒜汁或姜汁,可明显地抑制甘蓝乳酸发酵中亚硝峰出现;且在发酵过程中,泡菜的pH值对亚硝酸盐含量也有较大的影响。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中,河流河口在科氏力作用下,南移东伸,下切迅速;反之,海面快速上升的过程中,河口则迅速北跳西移,逐步退缩;两者力量对比相当时,在沉降盆地沉降中心东移,并向南掀斜的背景下,在科氏力与沿岸流作用下,发育微微南偏的三角洲,河口缓慢南移,相对稳定。

Elementary education base in the process, first, ranking, memorizing, the examination system, the paper sets in various methods of students' imagination and creativity, but will do topics, students can get a high score, test and seldom someone to ask "why" in the teaching process, the teacher teach students also focus on solving method, and not to teach students to ask "why", the teacher not only, and the evaluation standard is exam, is the so-called "test, teacher, student, expressed the Minge."

在中小学基础教育过程中,分数第一、排名、死记硬背、考试制度、试卷的设置等种种做法都在抑制学生的想象力和创造力,学生只求会做题目,考试能考出高分,而很少有人去问&为什么&,教师在教学过程中也只注重传授给学生解题的方法,而不去教你&为什么&,学生不问,教师不讲,唯一的评价标准是考试,正所谓&考考考,老师的法宝,分分分,学生的命根。&

In this paper, a controlled-atmosphere cone calorimeter was used to investigate the smoking property of wood treated with fire-retardant monoammonium phosphate and the untreated for comparison.

在相同的氧浓度下,当氧浓度在16%以上时,MAP阻燃木材燃烧过程中的浓烟释放(RSR、TSR和SEA)小于素材;而当氧浓度在16%以下时,MAP阻燃木材燃烧过程中的浓烟释放(RSR、TSR和SEA)反而高于素材。

The mian works are as follows:(1)By coprecipitation technique and coprecipitation- gel technique the nano zirconia powder was produced, factors affecting the properties of nano zirconia powder such as pH and the content of stabilizator are analyzed;(2)By the new pressless sintering process, the nano zirconia ceramic was produced, factors which can affecting the properties of nano zirconia sinter body such as moulding press and the sinter temperature are analyzed;(3)By the microtherm pressless sintering process, the nano copper added functional zirconia ceramic composite was produced, microscopic dimensionality and electric properties of such sinter body and the factors affecting such sinter body are analyzed;(4)By the self-invented "external albumen coating" technique the zirconia powder was successfully coated by carbon in the corresponding sinter body, which can help solve the traditional aggregation problem to some degree;(5)Based on analyze the characteristics in the nano powder sinter process, the "three-ball sinter model" was proposed, for the relationship between the relative density and porosity of sinter body, by mathematical fitting, such model was successfully verified.

Under the condition of laboratory incubation,the C loss of organicmaterials during their mineralization was greater than their N loss,inducing ahigher residual amount of organic organic N.During the decay of maize andrice staw with a wide ratio of C/N.soil microbes could fix N,but the fixationrate was quite low,only 0.2-0.9g N/assimulated 100g organic C.

在实验室培养条件下有机物料在矿化分解过程中C的损失总是大于N的损失,因此有机N的残留率明显高于有机C的残留;且由于灰分总量不变,有机物料的残留率也略高于有机C的残留率;〓比较宽的玉米秸和稻秸在腐解过程中发生了自生固N作用,但其固N效率仅为C:N=100:0.2-0.9,即每同化100g有机C,只能固定

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.

在1000℃左右的还原过程中,在金属铁出现之前,在数分钟内Fe_2O_3和Fe_3O_4几乎都已全部还原成浮士体,但后者还原成金属铁的阶段,则须经历数十分钟之久,因此后一阶段便成为还原过程中控制的一步。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.Therefore the last stage reaction controls the whole reduction process.
