在常温条件下，多效唑具有延缓早稻秧苗的伸长生长，促进分蘖，提高叶片含氮量和叶鞘淀粉含量，提高叶片组织电阻和叶绿素含量，提高游离脯氨酸含量等方面的生理效应；在低温胁迫条件下，多效唑能够减小秧苗叶片细胞膜透性，维持叶片组织电阻以及延缓叶绿素含量和净光合速度的下降趋势，提高脯氨酸含量，减轻回暖后秧苗的外部伤害程度。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

Climbing non-ornamental orchid bearing a podlike fruit yielding vanilla beans; widely cultivated from Florida southward throughout tropical America.

The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

After analysis and measure the microscopic morphology and mechanical properties of mulberry and tussan silks which are being treated with stanniferous salts respectively, it is found that the erosion resistance of silk fibers after the weighting treatment has changed.

对经锡盐处理过的桑蚕丝和柞蚕丝进行了微观形态分析和力学性能测试，发现增重处理后真丝纤维的抗侵蚀性被改变，桑蚕丝的内应力减小，蠕变伸长变大。

Thanks to our technology, highly tested in a great variety of applications, the extrusion line supplies a finished product which, through fully computerized process control, reaches levels of complete uniformity and quality as regards to width, thickness, weight, camber, breaking loads, elongations under load, weld ability and resistance to abrasion.

经过我们技术、高度考验繁多申请挤出了成品供应线，通过全面电脑过程控制、游完全一致的水平和质量至于宽度，厚度，重量，拱破负荷下伸长负荷焊接能力和耐磨性。

Therefore, for improving the accuracy of exceed slender axle on turning,must need to do with the lathe fixture and cutting tool for further improvement. In order to reached the requirements of precision machining,in machining process must use follower rest、flexible active thimble、space block and bracket etc fixture and assistive device.

超细长轴在车削加工中承受自身重力、切削力、高速旋转产生的离心力的作用，极容易出现振动与弯曲变形现象，增大轴的几何形状误差，而超细长轴的轴向尺寸较大，直径较小，热扩散性及刚性差，受切削热作用会在轴向发生线性膨胀，若在轴向的伸长量无法得到消除，轴将受迫弯曲，从而影响轴的精度。
