In one embodiment, the invention is a system for initiating free radical polymerization comprising: a in one part, one or more amido-borate compounds containing one or more anionic amido-borate moieties comprising an organoborate wherein the boron atom is bonded to a nitrogen atom of ammonia or an organic compound containing one or more nitrogen atoms, such as a hydrocarbyl amine, a hydrocarbyl polyamine, or an aromatic heterocycle containing one or more nitrogen atoms and optionally containing one or more heteroatoms or heteroatom containing functional moieties, and one or more cationic counter ions and b in a second part, a liberating compound which reacts with the nitrogen atom bound to the boron atom upon contact with the amido-borate to form an organoborane radical.

在一个实施方案中，本发明是引发自由基聚合的体系，包括：a在一个部分中，一种或多种含有一个或多个包含有机硼酸根的阴离子酰氨基-硼酸盐部分和一个或多个阳离子抗衡离子的酰氨基-硼酸盐化合物，其中的硼原子键合到氨的氮原子或含一个或多个氮原子的有机化合物，例如烃基胺、烃基聚胺或含一个或多个氮原子和任选含一个或多个杂原子或含杂原子的官能部分的芳族杂环的氮原子上，和b在第二部分中，在与酰氨基-硼酸盐接触时与键合到硼原子上的氮原子反应形成有机硼烷基团的释放化合物。

The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.

结果显示，心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低，分别在播种后第40 d和60 d出现峰值，30 d时皮中POD活性高于肉，之后则相反，酶活性最高时同工酶数目也最多，不同时期，皮和肉中同工酶种类不同；皮中POD同工酶由5个单体和4个二聚体组成，而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成，均以酸性同工酶为主；组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

The water content of external layer of root xylem of Kalidium foliatum is highest. In the range of root diameter from 0.3cm to 0.5cm,the most roots diameter are between 0.3cm and 0.5cm.

盐爪爪根的皮层含水量在径级为0.3－0.5cm范围内最高，大于0.5cm含水量反呈下降，而盐节木根径级在0.5－0.6cm范围内皮层和木质部含水量均最高，这可能是盐爪爪和盐节木根系径级分别多集中在0.3－0.5cm和0.5－0.6范围内的原因之一。

With the increasing of water lever, Myriophyllum spicatum increased the plant height, allocated more biomass to their leaves and decreased the allocation to roots and stems. However, Potamogeton maackianus allocated most biomass to their stems and decreased the allocation to leaves and roots.

实验发现：随着水位上升，狐尾藻株高也增加，并且将更多的生物量分配到叶片部分，减少对根和茎的资源投入；而微齿眼子菜则将生物量大部分投入到茎杆，减少对叶片和根的资源分配。

As the forward velocity increasing, the windrowing angle would be decreased, but the effect of forward velocity on windrowing distance was not obvious. The windrowing angle and distance of multiple sugarcane stalks would be smaller than those of single sugarcane stalk, but the maximum range of windrowing angle and distance of multiple sugarcane stalks would be greater than those of single sugarcane stalk. In order to sugarcane stalks outward windrowing, holding height must be within ±100mm of height of sugarcane mass center. As holding height increasing, the windrowing distance would be decreased, but the effect of holding height on windrowing angle was not obvious.

随着夹持输送装置输送速度的增大，甘蔗铺放角和甘蔗铺放距离也随着增大，随着机车前进速度的增大，甘蔗铺放角是减小的，而前进速度对甘蔗的铺放距离影响不大；多根甘蔗的铺放角和铺放距离要比单根甘蔗小，铺放角和铺放距离最大极差要比单根甘蔗大；入口夹持点高度应在甘蔗质心高度±100mm范围内为宜，以保证甘蔗能向机车外侧铺放，随夹持高度的增加，甘蔗质心位于夹持点下方的距离增大，甘蔗铺放距离减小，而夹持高度对甘蔗铺放角影响不大。

Meter length of pipe to be connected into more than 120 different root length, tilt angle diversified steel, more than 70% are double-inclined column -- a column in the vertical plane reversed twice.

边长一米的方钢管被连接成120多根长短不同、倾斜角度多样的钢柱，70％以上都是双斜柱——一根柱子在垂直面上扭转两次。

The results indicated that root border cell number of red cowpea increased rapidly with the elongation of root.

结果表明，红豇豆的边缘细胞数目先随着根的伸长而迅速增加，到根长为10mm时达到最多，约为5300个；随后，边缘细胞数目稍有减少，且较为稳定。
