大破坏

As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

Ironically, although this war had caused tremendous damages, the modern medicine developed leapingly during the World War I.

具有讽刺意味的是，虽然这场战争造成了很大的破坏，但现代医学却在&一战&期间有了飞跃发展。

It was analyzed by means of metallographical examination, chemical composition analysis and inclusion testing, the results show that the fracture was mainly caused by no-metallic inclusion.

通过对层裂坯料进行宏、微观检验、化学成分和夹杂物分析，认为大颗粒硫化物夹杂及其富集破坏了基体的连续性，是镦制过程中产生裂纹的主要原因。

Methods The damaged second metacarpophalangeal joint,distal part of the second metacarpal and proximal part of the proximal phalanx were dissected.The metatarsophalangeal joint was transferred to the region of metacarpophalangeal joint of hand.The dorsal pedis artery Was anastomosed to the radial artery ,and the great saphenous vein Was anastomosed to the cephalic vein at anatomical snuf-box. The dissected bones of the hand removed of the cartilage of joint and soft tissue were grafted back to the donor site of the foot.

手术切除破坏的第二掌指关节及部分第二掌骨和近节指骨，将第二跖趾关节转移至手部第二掌指关节处，在鼻烟窝处将足背动脉与桡动脉吻合、大隐静脉与头静脉吻合，将切除的第二掌指关节的软骨关节面和骨骼的软组织剔除后回植到足部第二跖趾关节供区。

During the chemical prevention and cure of Mikania micrantha, the number of protozoan taxa and the population dynamics of soil protozoan community were investigated, before and after the soil was exposed to various concentrations of the herbicide sulfometuron for two months.

结果表明：除莠剂森草净对土壤原生动物群落有较大的影响，在两个月后依然有可能破坏土壤生态环境进而影响土壤肥力及动植物的生长。

In the early Paleozoic and Indosinian cycle, the tectonic movement is weak, and the rock has acoustic emission once, whose maximum paleo-stress is 13.3MPa and 24MPa, moreover the Majiang ancient reservoir is in the mainly accumulation period; the high frequency and intensity paleo-stress correspond to the Majiang ancient reservoir's reservoir comes into being or destruction. The single Neopaleozoic acoustic emission whose maximum paleo-stress is 92.6MPa means the reservoir comes into being.

在早古生代末期和印支期构造运动较弱，测试岩石的发声一次，古应力值分别为13.3MPa和24MPa，是麻江古油藏的主要成藏期；声发射次数较多或者古应力值较大时的时期，主要对应于麻江古油藏储层的发育期和油藏大规模破坏期。

During rat's intracerebral hemorrhage processes, Glu is over released and accumulated in hypothalamus and brain tissues surrounding hematoma, which could induce the opening of 〓 and 〓 ion channels, and evoke cellular-toxic edema. Meanwhile it may also evoke 〓 influx into neurons. It is this 〓 influx that may activate phosphase and proteinase, disrupt protein and cellular skeletons, and further aggravate neuronic damage.

大鼠脑出血过程中Glu在下丘脑及血肿周边脑组织的大量释放和积聚，通过其开放〓离子通道，造成细胞毒性水肿，使〓内流激活磷酸酶和蛋白酶，破坏蛋白质和细胞骨架，加重NC的损伤过程。

The nanoplex were smaller than the unmodified nHAP; thelipiodol/nanoplex emulsion, with the mean diameter at 75±11.8nm can disperse moreuniformly and be more soluble and stable, contrary to the unmodified nHAP and nanoplex Conclusion: Nanoplex/pDNA mass ratios greater than 15 had exhibited completepDNA absorption onto positive charged polyplex and pDNA protection from thedestruction of nucleinase in rabbit serum. Unmodified nHAP may can\'t induce effectivegene delivery.PartⅡThe construction of the recombint eukaryotic expressive vector ofwild-type human p53 and RbObjective: To construct the recombint eukaryotic expressive vector of wild-type humanp53 and Rb by utilizing the theory of molecular medicine.

结果nHAP颗粒本身大小小于100nm，但由于颗粒表面本身带负电，不能包括有效地结合及保护DNA；经Ca~(2+)修饰后，颗粒可带正电，可一定程度地结合和保护DNA，但聚合物本身的中性电与带负电的细胞膜结合，而且本身的颗粒则变地容易聚集而成为很大的颗粒，也不利于细胞的吞噬；经PLL修饰后，颗粒溶解性提高，直径变小，表面带正电，电泳结果显示PLL-nHAP颗粒可包括有效地结合和保护DNA免受兔血清的破坏，而且复合物表面的正电也包括有利于与细胞膜的结合与吞噬。

Furthermore, the intensive uplift and erosion (up to 3000 m in thickness) at the end of the Palaeogene had severe negative effects on hydrocarbon ace umulation. On one hand, it caused decline of temperature and pressure, and resulted in slowdown of hydrocarbon gene ration and expulsion from source rocks; on the other hand, it destroyed the earlly formed oil-gas pools.

另外，本区地层在老、新第三纪之间遭受的强烈抬升剥蚀（最大剥蚀厚度达3000m ，对本区的油气生成和聚集更是产生了严重的负面影响：一方面导致源岩层的温度、压力下降，油气生成、排出作用大大减弱；另一方面，使得已排出并聚集成藏的油气遭到破坏。
