The results indicate that polyborazine precursor prepared at 150℃ for 10 h and propylamine/isopropylamine molar ratio 2:1, could possess nearly linear molecule skeleton and he prone to melt spinnability. When melt at 90℃, the precursor fibers are prepared with average diameter 10-20μm and BC1.27 N1.52 H structure. After curing process and sintered in NH3 at 1200℃, the near-stoichiometric BN fibers was obtained, which proved this precursor is apt for preparation of BN fibers.

结果表明，当正丙胺／异丙胺摩尔比为2：1，聚合温度为150℃，反应时间为10h时，合成产物具有近似线性分子结构，熔点为90℃，具有良好的成丝性，可获得平均直径10~20μm，组成为BC1.27N1.52H的先驱体纤维，先驱体纤维再经不熔化处理及1200℃氨气高温锻烧等工艺可获得近化学计量比的氮化硼纤维。

In mesothermal area where accumulated temperature is 2400～2850℃, the range of increasing production is the biggest, income increase is approximately 1700～2000y/hm2, which is the major region to popularize the technique. The range of increasing production is bigger in north of Heilongjiang Province where accumulated temperature is under 2200℃, it is comparatively suitable for popularizing the technique. Most areas of Liaoning Province where accumulated temperature is over 3000℃, the effect of production increase is not noticeable, and the technique is unsuitable.

在日平均气温≥10℃积温2400～2850℃的中温地带，即吉林省东部、黑龙江省东部和中北部，地膜增产增收幅度最大，增收额达1700～2000元/hm2左右，是主要推广区域；积温低于2200℃的黑龙江省北部地区增产幅度较大，也比较适合推广地膜覆盖；积温高于3000℃的辽宁省大部，增产增收很不明显，不宜推广该项技术。

统计检验表明，两类估算方程在不同固定相上的平均相关系数分别为0·952和0·965，均呈极显著相关(P·01)，可用于估算取代苯类化合物在草鱼体内的BCF，估算结果不受固定相极性的影响。

In this dissertation, polyethylene glycol monomethyl ether of 2000 molecular weight as soluble support, an array of soluble polymer-supported tartrate esters were designed, synthesized, and applied in asymmetric epoxidation of allylic alcohols.

本论文以平均分子量为2000的聚乙二醇单甲醚为可溶性支载体设计和合成了一系列可溶性聚合物支载的酒石酸酯配体，并将它们用于烯丙基醇的不对称环氧化反应。

Beach groundwater table fluctuates with tidal oscillations in coastal unconfined aquifer. The period-averaged water table height is higher than the steady-state water table with the neglect of tidal effects. That is, there exists an overheight between the two.

潮汐海平面上下波动带动毗邻的滨海地下水水位振动，对达到动态稳定后的地下水水位作周期平均后，其位置高出不考虑潮汐作用的稳态水位，即潮汐影响下滨海地下水水位存在超高。

While the causes of individual building failures remain unclear, such complaints underscore widespread concerns about the quality of much of China's infrastructure amid an un- paralleled but only patchily supervised national building surge.

尽管建筑物倒塌的具体原因尚不明朗，但网上的这些抱怨，突显人们对于中国许多基础设施质量的普遍担忧。近年来，中国全国投入空前规模建设高潮，但质量监督并不平均。

Methods: 48 casted Ni-Cr alloy metal specimens (12.0 mm×1.0 mm) were fabricated with ShoFu Vintage Halo porcelain and divided into six groups , eight pieces for each group. They were polished against 200-, 400-, 600-, 800-, and 1,000-grit sandpaper after body porcelain sintered, respectively. The specimens in a sixth group not polished was used as control. Surface roughness and Color parameters of the specimens were measured with a Surface Roughometer EX2154-13 and a spectrocolorimeter respectively.
