调节

In the research of prescription, through the experiments we knew the influence from the Nb_2O_5 or Y_2O_3 single donor doped on high-temperature PTC ceramic, and got the curve graph drawing the resistivity and mixing quantity. In order to restrain lead volatilize and mix the rang of donors to neutralization the harmful acceptor impurity in raw materials, adopt the prescription design of Nb_2O_5 and Y_2O_3 double donors-doped. From the result, we know that regulation proportion of Nb , Y double donors, can make high-temperature PTC ceramics semiconducting, the pottery demonstrates good electric performance.

为了能够更有效的抑制铅挥发，并且使掺杂范围能够更好的调节，以"中和"原材料中的有害受主杂质，在配方设计中采用了Nb_2O_5和Y_2O_3双施主掺杂的配方，由结果可知，适当的调节Nb、Y双施主掺杂总量及Nb、Y掺杂比例，可以使高温PTC陶瓷充分的半导化，陶瓷表现出良好的电性能。

Constant Flow Valve and the constant flow regulating valve are different: there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve, the implementation of change in valve resistance action can be "direct action type variable resistance valve "It should not regulate the flow line, so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run, and this set the flow valve as there are no imports of expensive, in the past, domestic heating systems seldom used, and only at some central air conditioning system to see.

定流量阀和恒流量调节阀不同的是：定流量阀只有一个阀瓣，由这个阀瓣直接感受阀门的前后差压，执行改变阀门阻力的动作，可成为"直动式变阻力阀"，它不能在线调节流量，因此使用定流量阀无法实施改变总流量的节能运行，而且这种定流量阀国内没有，进口的价格昂贵，以往国内的供暖系统很少采用，只有在一些中央空调系统中见到。

Constant Flow Valve and the constant flow regulating valve are different:there is only one fixed flow valve valve from the valve directly feel before and after the differential pressure valve,the implementation of change in valve resistance action can be"direct action type variable resistance valve",闸阀;It should not regulate the flow line,so the use of Constant Flow Valve can not be implemented to change the total flow of energy to run,and this set the flow valve as there are no imports of expensive,in the past,domestic heating systems seldom used,and only at some central air conditioning system to see.

订流量阀和恒流量调节阀不同的是：定流量阀只需一个阀瓣，由这个阀瓣直接感受阀门的后后佳压，执行转变阀门阻力的动做，否成为"直动式变阻力阀"，facebook外白板，它没有能在线调节流量，研建课，因己运用定淌量阀无法实施改变合流量的节能运行，而且这种定流量阀海外不，入口的价钱昂贵，以来国内的供暖体系很少采用，只需在一些中央空调系统内见到。

During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

Therefore, the robust feedback linearization control is obtained.(2) For affine nonlinear systems with parameter uncertainties, a novel nonlinear state observer is constructed. Under nonlinear feedback control based on observed state, the regulated system state is guaranteed to enter and remain in a enough small neighborhood of origin.

Deficiency of selenium in chicken decreases immunity of erythrocyte and the regulation of erythrocyte to the specific immunity, which includes the decrease of the phagocytic ability of phagocyte, the eliminating ability of circulatory immune complex, the ability of identifying organism, carrying antigen and the immune regulation effects in the activation course of T lymphocyte, B lymphocyte, NK cell alexin, which decreases immunity of organism.

雏鸡硒缺乏降低了红细胞免疫力；同时降低了红细胞对特异性免疫的调节作用，主要表现为降低了吞噬细胞的吞噬能力、清除循环免疫复合物能力、机体识别和携带抗原能力以及对T、B淋巴细胞、NK细胞补体的活化过程的免疫调节作用，结果使机体免疫力下降。

Materials and methods: The composite was respectively prepared by blending Lysine, Histidine, Arginine with PLGA, while the composite respectively prepared by blending Algin, chitosan, NaHCO3 with PLGA as the comparison and the pure PLGA as the control. All composites were degradated in tri-distilled-water at 37℃ for 7 weeks.
