Sio _ 2 nano particle concentrates in the boundary lubricant film in the process of friction can repair the wear surface , embody the fine anti - wear performance Sio _ 2纳米微粒,在摩擦过程中富集在边界润滑膜内,能够对磨损表面起到修复作用,表现出优良抗磨性能。
Direct self - repairing control is a basic method proposed by paper [ 33 ] in 1999 , which absent the time sequence of traditional repairing system , the repairing action would play its role at the moment the fault occurs without knowing failure modeling in advance 直接自修复控制是文在1999年提出的基本方法,它抛弃了传统自修复系统的固定时序,修复作用在故障发生时就立即开始,而无须先辨识故障模式。
Abstract : the study summarized the recent advances of experimental researchin the treatment of ischemic cerebral apoplexy with acupuncture ; the advances of improving the injury of ischemic cerebral apoplexy and the regulation mechanism of acupuncture 文摘:本文就针刺治疗急性缺血性中风中有关针刺对脑缺血组织损害的修复作用及其调节机制的实验研究的最新进展作一综述,并对研究结果及意义进行了一定的探讨。
Is not high . recovery of cells depends on the degree of initial damage and may be different for different individuals . understanding the effects of radiation on human bodies provide useful information for the development of radiation protection measures 不高,机体可以通过自身的代谢过程对受损伤的细胞或局部组织进行修复,这种修复作用程度的大小,既与原初损伤的程度有关,又可能因个体间的差异而有所不同。
Etc . ) by the ionization of water molecules due to radiation may lead to changes in molecules that are biologically important for the functioning of cells . although radiation can cause damage to living tissues , human cells however can repair the damage through natural metabolic processes if the 不高,机体可以通过自身的代谢过程对受损伤的细胞或局部组织进行修复,这种修复作用程度的大小,既与原初损伤的程度有关,又可能因个体间的差异而有所不同。
In the meantime , congenital amblyopia resulted from optic nerve lesion was observed in the crested ibis , with an incidence rate of 3 - 5 % . since the epilepsy and congenital amblyopia are both hereditary , it is feasible to perform genetic engineering studies on the correlative genes , which could protect neurons from the damages of excitation toxin and vision sickness , in order to cure the diseases at gene level 由于癫痫和视神经病变类疾病均属于遗传性疾病,因此,利用分子生物学技术,对因癫痫和遗传性弱视症导致的神经元损伤具有保护及再生作用,以及视神经通路的发育、分化和受损视觉通路具有修复作用的相关基因,开展克隆、表达和活性鉴定之研究,将为通过基因工程技术实现其疾病治疗之目标奠定基础。
Compared to the control , concentrations of cu and zn in e . splendens were significantly higher in the treatment of edds plus microbial product , and then markedly enhanced plant cu and zn uptake . edds application alone increased pb concentration in the above ground parts of e . splendens plants . the treatment of microbial product or chitosan alone had no significant effect on metal concentrations in e . splendens 发现3mmoll ~ ( - 1 )乙二胺二琥珀酸( edds )和微生物制剂的联合处理可以极显著地提高海州香薷地上部铜含量与积累量,同时也提高植物对铅、锌的吸收量,强化了复合污染土壤的植物修复作用。
Methods : according to the concepion meridian ' s transmission , du meridian is " the sea of yang meridians " , ren meridian is " the sea of yin meridians " and yin - yang equilibrium theory , we can guess that not only du meridian can recover the cerebral ischmia ' s harm , but also ren meridian maybe have significance 方法:根据任脉循行,从督脉为阳脉之海、任脉为阴脉之海、阴阳平衡学说等理论,推测不仅督脉对脑缺血损伤有修复作用,任脉在脑缺血损伤中可能也起着非常重要的作用。
The nano diamond particle improve friction surface lubricate condition , mainly by the nano particle repair and inlay effection nanometer particle deposition in the friction contact region , fills the friction damage spot promptly , has the repair function , simultaneously prevents the crack from further development , achieves the goal of prolong fatigue life 纳米金刚石微粒通过微粒修复作用和镶嵌作用,改善摩擦表面的润滑状态。在摩擦过程中,纳米微粒沉积在摩擦接触区域,填补摩擦损伤部位,起到修复作用,同时阻止裂纹的进一步发展,延长了陶瓷球疲劳寿命。
Experimental results revealed that the carrier mobility increased with increasing of the annealing temperature , in the range of the annealing temperature from 650 ? to 850 ? , which implied that the crystal lattice structure was damaged by ion implantation and restored after annealing . furthermore , the square carrier concentration decreased , and the square resistance of the samples implanted by mn + and c increased with the raising of annealing temperature . these results indicated that the second phase such as mnga , mnas ferromagnets was formed by more mn + ions with increasing of the ( gaas ) annealing temperature , so the mn + ions which can provide carriers decreased 由实验结果可以知道在退火温度为650 850范围内,样品的载流子迁移率随着退火温度的提高呈上升趋势,说明杂质元素的注入对样品造成晶格损伤,但退火对这些损伤具有修复作用;此外,随着退火温度的上升,样品的方块载流子浓度不断下降,加c样品的方块电阻不断上升,这都是因为随着退火温度的提高,掺入的mn ~ +离子不再提供载流子,而是形成了mnga 、 mnas等磁性第二相。
