Shenyang Research Institute of Chemical Industry, Shenyang 110021, China Abstract: Spectrophotometric analysis showed that the peak absorbance for food dye of Allura Red and biological dye of Ponceau-G occurred at 501 and 510 nm. In sunlight after 2, 4, 6, 8, 10 hours, the decomposition rates of Allura Red and Ponceau G were between 2.4 to 5.8% and 3.4 to 10.8%, so they are stable in sunlight. The recovery rates on cottons and glasses were very high, so they are easily recoveried from targets. Further studies showed that the recovery rates of two dyes on the leaves of wheat, cabbage, cucumber and tomato were different, so it need previously determine the recovery rate of tracer on the target crop to adjust the result. Field experiment showed it was easy to measure the pesticide spray distribution of high volume spay and low volume spray to use Allura Red and Ponceau-G as tracers.

沈阳化工研究院，沈阳 110021 摘要：光谱分析表明，食品染色剂诱惑红和生物染色剂丽春红-G的最大吸收波长分别为501 nm和510 nm ；在连续2、4、6、8、10 h阳光照射下，分解率分别在2.4%~5.8%和3.4%~10.8%之间，见光稳定性良好；两种染色剂在棉花叶片和玻璃片上的洗脱回收率都很高，说明易于从靶标上洗脱下来；进一步测定表明，两种染色剂在小麦、甘蓝、黄瓜、番茄叶片上的洗脱回收率各不相同，所以对准备进行测试的作物应先做一次洗脱回收率试验，用以校正测试结果；田间应用表明，用两种染色剂做示踪剂，可以方便地测定常量喷雾和低容量喷雾过程中农药在麦田的沉积分布情况。

The effects of temperature on the mycelial growth of Rhizoctonia solani AG-l-IA and on its infection in maize were also studied.

本文从四个方面进行了研究：(1)研究了苯丙氨酸解氨酶生理病理变化及其与抗病性的关系；(2)在人工控温条件下，研究温度对玉米纹枯病菌菌丝生长、菌核萌发和侵染的影响；(3)建立人工病圃，系统监测玉米纹枯病的田间发生动态；(4)采用人工接种方法对一批玉米材料进行抗纹枯病的鉴定和评价，继续寻找新的抗源和抗性评价指标。

Through selection we obtained transgenic restorer line T773-1 with good agronomic traits and obvious resistance to striped stem borer and herbicide.

3转cry1Ab和bar基因的水稻恢复系T773-1和转Xa21基因的恢复系T773-2进行杂交、自交，对自交世代单株进行cry1Ab、bar和Xa21基因的分子标记辅助选择，获得了带有三基因的恢复系T773，田间种植对水稻白叶枯病、鳞翅目害虫、除草剂具有很好的抗性。

It was the first time to classify the 12 tested stylo genotypes into four different groups based on P efficiency and P acquisition efficiency according to Lynch's way as indicated by shoot dry weight and P content in two different sample time.

在划分的四种类型中，不同基因型柱花草总磷效率在分类图中的分布规律与磷吸收效率分类图中的分布规律非常相似，表明了田间条件下柱花草的磷效率是由磷吸收效率所决定的。

Combined with the characteristics of mobile network such as high covering rate, and simpleness of sending short message, GSM (global systems for mobile communication) is prevalent. With the support of hardware and software, the data investigated artificially from the field are sent to the GSM modem of the teledata server by normal format of short message.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
