This article have analyzed the major problems basing on functionalized management in Longquan glasswork company ,and it also points out that the original functionalized management pattern is no longer answer to the market changes and development. So to promote a new management pattern----project management will be a better option to the company.
本文针对龙泉玻璃公司职能化管理模式存在的主要问题进行分析,指出原有的职能化管理模式已不能适应市场的发展变化,而在公司中推行一种新的管理模式——项目管理是个更好的选择。

Intravitreous injection of rhCTGF alone did not produce PVR, whereas such injections into rabbits with mild, nonfibrotic PVR promoted the development of dense, fibrotic epiretinal membranes.
玻璃体内单独注射rhCTGF不能诱发PVR,然而,在兔眼内这样的注射伴随和缓、非纤维化的PVR可以促进视网膜外层膜的浓密发展。

At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.
结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力,这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径;在PAN- Fe_3O_4超滤膜中,四氧化三铁与PAN在室温下没有形成化学键,也不存在官能团之间的相互作用;添加Fe_3O_4对膜的玻璃化温度没有影响,但能提高PAN环化脱氢反应的温度和分解温度;PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性,在pH值为10以上的溶液中由于水解作用而溶解,使得膜失去使用价值,膜的耐酸性与酸的种类、浓度和氧化性有关。

Two series of polyurethane acrylate grafted acrylic resins (Acr-g-TPU-PETA and Acr-gPPU-PETA) self-emulsifying systems are obtained by grafting -NCO group modified polyurethane acrylates with acrylic copolymer prepared from n-butyl acrylate, styrene,βhydroxyethyl methacrylate and acrylic acid The self-emulsifying systems showed Newtonian fluidity with viscosity closed to that of water, the solid contents were around 30% The T〓 of 15~4℃ for dried film before photocuring favored film formation at room temperature DSC and DMA results showed that PU-PETA is compatible with acrylic resin in the grafted resin The TG and dTG curves for Acr-g-PU-PETA samples were substantially different from the corresponding blends, and the brodened dTG peaks for photocured grafted resin suggest that there might be multiple interactions among chain segments The photocued film of the grafted resins self-emulsifying system exhibited good overall properties with polyurethane acrylate grafts ranging from 30% to 50%, and Acr-g-TPU-PETA series showed better properties than Acr-gPPU-PETA series The adhesion of the photocured film was 1~2 grade, impact strength was 50kg-cm and flexibility was 1mm The Shore hardness and the adhesion of the film decreased markedly if PETA was replaced by HEMA as photoactive group due to the lower C=C double bond content in the grafted resin The polyhydroxy amine-linked thioxanthones photoinitiators can be evenly dispersed in self-emulsifying system without color spot appearing in the dried film The films photocured with IV〓~IV〓 generally exhibited higher Shore hardness, gloss and solventresistance than that cured with Irgacure 2959 and did not induce the rusting of the iron substrate Pigmenting with titanium oxide had no effect on the photocuring The polyhydroxy amine-linked thioxanthone IV〓 and IV〓 can be new candidates for the formulation of titanium oxide pigmented photocurable water-borne coatings for their pale-yellow appearance and slight interference with the color of the coatings WB 4759 with high water-solubility coalesced and separated from the dried resin film, and even induced the rusting of iron substrate.
以丙烯酸丁酯,甲基丙烯酸-β-羟乙酯,丙烯酸及苯乙烯合成厂丙烯酸共聚树脂,并与含-NCO端基的聚氨酯丙烯酸酯接枝反应,经水性化后,得到两个系列(Acr-g-TPU-PETA和Acr-g-PPU-PETA)各5个不同配比的丙烯酸树脂接枝聚氨酯丙烯酸酯自乳化体系,粘度与水相近,为牛顿流体,固含量30%左右。光固化前干燥涂膜的玻璃化转变温度在-15℃~4℃之间,有利于室温下成膜。DSC及DMA谱表明两种树脂基本相容。Acr-g-PU-PETA的热失重行为明显不同于共混材料,接枝样dTG峰明显宽化,表明接枝样中链段之间的相互作刚有多重性,丙烯酸树脂与聚氨酯之间有一定的相容性。接枝树脂自乳化体系光固化涂层的综合性能以聚氨酯丙烯酸酯成分为50%~30%者相对较好,且以Acr-g-TPU-PETA系列更理想。光固化膜的附着力为1~2级,冲击强度为50kg·cm,柔软性多为1mm。以HEMA代替PETA作为接枝树脂的活性基团,碳—碳双键密度太低,光固化膜交联点太少,硬度和附着力均较差。多羟基胺连硫杂蒽酮光引发剂能均匀分散于树脂自乳化体系和接枝树脂干膜中,不出现色斑,光固化膜肖氏硬度一般高于以Irgacure 2959为光引发剂的光固化膜,光泽度及耐丁酮溶剂性能均有所提高,不会诱导铁基生锈,钛白着色对光固化结果几乎没有影响。本论文所合成的多羟基胺连硫杂蒽酮光引发剂IV〓与IV〓为浅黄色,对光固化涂层的颜色干扰较小,为配制钛白着色光固化水性涂料提供了新的光引发剂。水溶性太强的WB 4759在干膜中易聚结析出,且对所附着的铁基有诱导锈蚀作用。

After crystallization silicide is finished, the density of the silicified wood is very high, the hardness can also reach 6.5-7.0 grades, like glass, much harder, similar to the gem (more than 7 grades) than the marble (4 grades), the timber of so high hardness, it can not moved that the wood is sawn, can't saw to cut open with the general stone material either.
在硅化结晶完成之后,硅化木的密度是很高的,硬度也可达到6.5-7.0级,与玻璃一样,比大理石(4级)要硬得多,与宝石7级以上)相似,如此高硬度的木材,木锯是啃不动的,也不能以一般石材来锯剖。

The storage modulus is increased with the increase of Cf, while the peak temperature of loss factor and the temperature of loss modulus are not changed with the variation of Cf, which means that the reinforcement of chitin fiber has no effect on the motion of molecular segment for PCL.
动态热机械分析表明,复合材料的储能模量随纤维含量的增加而增加,表征玻璃化转变温度的损耗因子松弛峰的峰值温度和损耗模量的温度都不随纤维含量的改变而变化。
