How could you forget that with all their simplicity, earnestness and unyieldingness, they are symbolic of our peasants in the North? How could you fail to associate them with our dauntless soldiers guarding our homeland all over the vast rear? How could you fail to see that these trees , ever striving to put out their closely knit branches and leaves in an upward direction, are symbolic of the spirit and will of our men who, fighting heroically all over the northern plains, are writing the history of New China with their own blood?

难道你就不想到它的朴质，严肃，坚强不屈，至少也象征了北方的农民；难道你竟一点也不联想到，在敌后的广大土地上，到处都有坚强不屈，就象这白杨树一样傲然挺立的守卫他们家乡的哨兵，难道你又不更远一点想到这样枝枝叶叶靠紧团结，力求上进的白杨树，宛然象征了今天在华北平原纵横激荡，用血写出新中国历史的那种精神和意志。

Growing sweet corn in summer could absorb redundant nutritional ingredients largely in the soil, but the number of fungi was high and the ratio of B/F is not obvious compared with CK. On the contrary, planting leafy vegetables had no obvious effect on the composing of soil microbe and the decruce of the number of pathogen of cucumber, although it could reduce the content of salty in the soil. The crop green manure of villose vetch could reduce the content of salty in the degree, but the sum of microbe in the soil reduced a little.

夏季休闲期间种植甜玉米可大量吸收土壤中多余的营养成分，但真菌数量偏高，B/F值与对照相比相差不大；种植速生叶菜虽然能降低土壤盐分含量，但对降低黄瓜致病菌数量和改善微生物区系组成方面无显著效果；豆科作物毛苕子在一定程度上降低了土壤盐分含量，但土壤微生物总量有所减少。

When his letter to mrs. weston arrived, emma had the perusal of it; and she read it with a degree of pleasure and admiration which made her at first shake her head over her own sensations, and think she had undervalued their strength. it was a long, well-written letter, giving the particulars of his journey and of his feelings, expressing all the affection, gratitude, and respect which was natural and honourable, and describing every thing exterior and local that could be supposed attractive, with spirit and precision. no suspicious flourishes now of apology or concern; it was the language of real feeling towards mrs. weston; and the transition from highbury to enscombe, the contrast between the places in some of the first blessings of social life was just enough touched on to shew how keenly it was felt, and how much more might have been said but for the restraints of propriety.- the charm of her own name was not wanting. miss woodhouse appeared more than once, and never without a something of pleasing connexion, either a compliment to her taste, or a remembrance of what she had said; and in the very last time of its meeting her eye, unadorned as it was by any such broad wreath of gallantry, she yet could discern the effect of her influence and acknowledge the greatest compliment perhaps of all conveyed. compressed into the very lowest vacant corner were these words - I had not a spare moment on tuesday, as you know, for miss woodhouse's beautiful little friend. pray make my excuses and adieus to her.' this, emma could not doubt, was all for herself.

他寄给威斯顿太太的那封信，爱玛也看过了，她看信时心情有些激动，因此最初她对自己的感觉有点怀疑，觉得以前没有料到那些感觉的力量如此之大，信写得很长，而且写得不错，他在信中叙述了外地和当地的一些十分有趣的事情'诉说了有关此次旅行情况和他的所感所想，他所有的爱'感激和崇高的敬意都流露于笔端，字里行间没有什么道歉和关心的话语，只有对威斯顿太太表达了真情实感的词句，他从海伯利去恩斯科姆，对两地的社会生活作了分析和比较，由此可以看出，他对这方面的感受相当强烈了，同时也透露出，出于礼貌，他只点到为止，要不然，会写得更多，信中还多次提到她本人的名字，每次谈及时，都带着一种快活的联想，要么夸奖她，要么重温她所说的话，信中最后一次出现她的名字时，尽管没有说出那么多恭维的话，但她还是可以感觉到自己的魅力所在，而且承认他给了她最高的评价，在信笺的最下面密密麻麻地写着，你知道，星期二我没能抽出时间去看望伍德豪斯小姐的那位美丽的小朋友，请代我向她道歉和告别，爱玛深信不疑，这全是冲她而写的，他没有忘记，哈

Contrasting with the control strain of Shigella sonnei, the test strain could be higher antibiotics rate, and it could not be agglutinated by several anti-sera to Shigella sonnei, which were in the period of validity, but the control strain could be well agglutinated.

检测试验菌株的生化特性和对抗生素的敏感性，以及用多种批号的诊断血清进行凝集试验。结果：具有典型的宋内氏志贺菌的生化特性；与对照菌相比，有较高抗生素耐药性，对复方新诺明等多种抗生素耐药。

Results: 1. The value of all experimental indexes decreased significantly after heat stress, and reached the lowest at the time 2-8 hours after heat stress. This indicates that the immunity of the mice is damaged to the largest extent at 2-8 hours after heat stress. 2. L-arginine supplementation with appropriate dose could remit the acute atrophying of thymus and spleen tissue caused by heat stress. 3. After L-arginine supplementation with appropriate dose, the lymphocyte proliferation, the level of concentration of IL-2 and * expression of IL-2R raised in the group with room temperature; in the heat stress group the level of three indexs decrease significantly. Furthermore, the decrease of the group given 1 .Smglg.bw L-arginine is the smallest. This result indicates that the concentration of 1 .Smglg.bw L-arginine supplementation could remit the depressment of the immunity caused by heat stress. 4. The [Ca2~] in activated thymocytes of the group with L-arginine -2- supplementation is significantly higher than that of the group with water supplementation. This indicates that L-arginine supplementation could protect thymoeytes of mouse under heat stress. We also found that the fluorescence intensity of [Ca2~] in activated thymocytes of the group given 1 .Smglg.bw L-arginine is the highest.

结果：1、热应激后小鼠的各项免疫指标均有显著性下降，其中在2.8小时降到最低，提示在这个时间段小鼠的免疫功能受到最大损害；2、适量补充精氨酸有助于缓解热应激导致小鼠胸腺和脾脏的急性萎缩；3、常温组，补充适量精氨酸后小鼠淋巴细胞增殖活性、IL-2的浓度及IL-2R的表达均有显著性上升，而热应激后三指标均显著降低，其中在精氨酸给予浓度为1.5mg/g.bw时三指标的降低程度最少，提示该浓度可最大程度缓解热应激对小鼠免疫功能的抑制；4、补充精氨酸组的活化胸腺细胞［Ca~(2+)］较给水组有显著性上升，说明精氨酸对热应激小鼠胸腺细胞具有保护作用，并发现在精氨酸给予浓度为1.5mg/g.bw时活化胸腺细胞的胞浆钙离子荧光强度达到最大；5、热应激后小鼠血清NO的浓度均有不同程度的上升，补充精氨酸后血清NO上升更加明显，但并非随精氨酸给予浓度的增加而增加。

Numerical simulation results showed that the unstable periodic orbits of the system could be ballasted,the chaos could be eliminated via choosing proper delayed time and gain coefficient,and the system could be changed from unstable to s.

The Fe^0 concentration and pH had optimal values during the decolorization of X-BR in Fe^0-anaerobic biological system. When Fe0 dose, initial pH value and X-BR concentration were 400 mg/L, 7 and 100 mg/L respectively, the decolorization rate of X-BR in the integrated system could reach up to 90% after 68 h reaction. Compared with pure Fe^0 and pure microorganism treatment systems, it could be improved about 40% under the same experimental conditions. In addition, the analysis result of UV-vis spectrogram indicated that Fe^0 could promote effectively biodegrading of anthraquinone dye X-BR and its intermediate products.

结果表明，在Fe^0-厌氧微生物体系中，Fe^0投加量和pH值均存在最适宜值，当两者分别控制在400mg/L和7，染料初始浓度和反应时间分别为100mg/L和68h时，该体系脱色率可达到90%以上；与相同反应条件下的纯Fe^0、纯厌氧微生物体系相比，该体系的脱色率提高近40%根据紫外可见光谱分析，Fe^0可有效促进厌氧微生物对X-BR及其中间产物的降解，实现完全脱色。
