Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

Through the experiments on hydration of AH in the following sulphate（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）, dissoluble sulfate hydrate origining from hydration process of AH affects it's hydrous rate, hydrous rate of AH does not connect with Z/R of cation in stimulation, theory that Z/R affect hydrous rate of AH does not exist. Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.

通过对CaSO_4在Na_2SO_4 、K_2SO_4 、Rb_2SO_4 、Cs_2SO_4 、(NH_4)_2SO_4溶液中水化过程，以及CaSO_4·2H_2O、CaSO_4与以上硫酸盐反应速度、产物的研究，说明复盐理论不正确；CaSO_4在（Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO_4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4）溶液中水化，水化过程中硫酸盐水合物的析晶影响着无水硫酸钙水化，与激发剂阳离子Z/R值大小无关，阳离子的Z/R参数影响水化率的规律并不存在； 3、无水硫酸钙在可溶性硫酸盐中的水化按照溶解-成核-生长理论进行，CaSO_4达到溶解平衡时Ca~2+的浓度大于CaSO_4·2H_2O溶解平衡的Ca~2+的浓度，CaSO_4·2H_2O获得结晶的驱动力，可溶性硫酸盐起到形成晶核的作用：水化过程与CaSO_4生成复盐或析出水合物所形成的细小物相，作为异质微粒使母相中存在不均匀性，这些不均匀性有效地降低成核时的表面能位垒，使CaSO_4·2H_2O晶核优先地在这些具不均匀性的地方形成，因此这些物质起成核催化剂作用。

The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

The main reason causing the defects and low angle boundaries in SC casting is the perturbations of heat flow and the slight misorientation at the S/L interface. An uniform and unidirectional heat flow is required to produce a single crystal casting free of low angle boundaries or splaying

单晶组织中由于晶体取向与热扩散场综合作用因素造成的亚单元生长形态的改变是造成单晶缺陷的主要原因，控制均匀、严格单向性的热场，并利用单晶生长的各向异性特性，可以避免发散型枝晶组织和小角度晶界的出现。

Use a good quality liquid or water soluble fertilizer with a formulation low in copper.(High amounts of copper are toxic to bromeliads.) We recommend 10-5-5 plant food. Normally dilute the suggested dosage to 1/4 strength. Fertilizing is not absolutely necessary to survival, but will increase the growth and vigor of your plants and their blooms.

用高质量的液态或水容性的肥料，要求使这些肥料中的铜含量必须非常的低（铜含量过高会毒害到铁兰），我们推荐10：5：5的肥料，正常的稀释浓度使1／4茶匙肥料用水一加仑，肥料并不是植株生长的唯一要素，但是却可以加速植株的生长速度和增加开花量。
