The methods to reduce the ethanal content in chips were expounded, such as reducing the reaction temperature, decreasing the final poly-condensation liquid level properly, stopping using the recovery EG and adding stabilizer.

介绍了低醛超有光聚酯切片的开发，阐述了降低切片中乙醛的质量分数的方法，即：降低反应温度，适当减少终缩聚反应的液位、停用回收EG、加稳定剂等。

In the thesis, we wish to report the synthesis and structures of a series of new type rigid conjugated nanometer-sized fulvene ligands, and coordination polymeric compounds based on both metal-carbon and metal-heteroatom interactions and also H-bonded supramolecular architectures generated from this new type of fulvene ligands.

基于此，我们合成了一系列刚性共轭的纳米级富烯类配体，并以之与过渡金属离子反应合成了同时基于金属-碳和金属-杂原子两种键合作用的有机-无机配位高聚物及以氢键作用为驱动力的超分子聚集体。

Three new fulvene polymeric compounds, namely 1[Ag (L3]CH2C12 , 2[Ag2(L25(H2O)(S03CF3)2]0.5C6H6 and 3 Mn(L42(C2H5OH)2 , were synthesized, respectively. Compounds 1 and 2 reported herein represent the organometallic polymers based on both Ag-N and Ag-C coordination interactions. In the solid state, compound 3 are bound together by strong intermolecular N H-O hydrogen bonding system into a supramolecular one-dimensional H-bonded chain.B.

一、富烯有机配体的合成及与金属离子的反应化学利用富烯负离子的芳酰化反应和Heck-偶联反应合成了富烯配体L1-L18，并合成了三个基于富烯配体的金属有机配位聚合物1[Ag(L3]·CH_2Cl_2、2[Ag_2(L25(H_2O)(SO_3CF_3)_2]·0.5C_6H_6和氢键驱动的超分子聚集体3Mn(L4_2(C_2H_5OH)_2。

For thecrystal in MeOH, X-ray single-crystal analysis reveals that each Schiff base provideone iminic N, one phenolic O and one hydroxylic O to chelate the four Cu andthus resulted in a pseudo-cubane structure. Different from the crystal obtained inMeOH, each Cu are tetra-coordinated not penta-coordinated.

充分证明了所设计的Schiff碱配体是一种桥联配体，不仅在配位形式上有多样性，而且在晶体排列方面也应具有多样性，是构建具有新颖物化性质及结构的超分子聚集体的良好前体。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
