The contents of crude protein and 18 kinds of amino acids in the powder of tetraploidy black locust for fodder leaves at four stages,from which Langfang,Hebei Province,were determined.Their value for feeding were evaluated by means of amino acid scores and essential amino acid index.

测定了廊坊地区饲料型四倍体刺槐叶粉4个不同时期的粗蛋白质含量及18种氨基酸组分，用氨基酸分和必需氨基酸指数对其氨基酸营养进行评价，并结合其生物量对最佳刈割时期进行了分析。

Result shows that the Apriona germari adult insect prefer to eat Broussonetia papyrfera and reject to eat other tree species which result in difference in natural life and fecundity. Total sugar and dissolvable protein content in the bark is not the cause of rejection. Difference of dissolvable sugar and amino acid may be the reason of preference while difference of dissolvable phenolics and tannin content may explain the rejection.

取食构树的桑天牛成虫取食量大，存活时间长，产卵量大，遗卵量少，其他3个树种则相反。4树种树皮内总糖和可溶性蛋白含量与桑天牛抗性无关，树皮内可溶性糖含量、总氨基酸和必需氨基酸含量对抗性有一定影响。4树种树皮内水溶性总酚含量和单宁含量差异对成虫取食有较大影响，酚类和单宁等次生物质对桑天牛成虫的忌避作用是导致抗性的主要原因。

Recently,the control of power supply of high frequency switch has been developed towards the "high refined and cuspidate" direction.Although the parts of apparatus have small volume and refined precision,the Electro Magnetic Interference and radiation are much stronger than before.

现在的高频开关电源控制已向&高、精、尖&方向发展，这些器件体积小、精度高，但电源内部的电磁干扰、辐射比原来更强了，为了使高频开关电源在预期的电磁环境下能正常工作、无性能降低及故障，并对电磁环境中的任何事物不构成电磁干扰，必需对其进行电磁兼容。

Moreover, because the decompounding to the basement membrane and intramatrical is extremely important to the move of endothelium cell which is essential to the blood vessel forming.

另外，因为对基底膜和基质组织的降解对血管生成所必需的内皮细胞迁移极为重要，所以，认为MMPs是肿瘤血管生成的关键之一。

In the second trial, five groups of diets with isonitrigenous (40% protein) and isoenergetic 20 MIJg^(-1 gross energy and different relativity of essential amino acid balance with soybean protein replacing 0.0%, 13.5%, 27.0%, 40.5% and 54% of fish meal protein, were formulated to determine optimal replacement level of soybean protein to fish meal protein.

实验Ⅰ以褐鱼粉为蛋白源，配制5个蛋白水平(31.04%、35.51%、40.89%、46.62%、50.33%)的等能、等必需氨基酸平衡关联度的半精制饲料，探讨翘嘴红鲌对饲料蛋白的需求；经过8周饲养，实验Ⅰ的结果表明，饲料蛋白含量对翘嘴红鲌的增重率、饲料效率和蛋白效率具有显著影响。

Methods:clinical data of all the 1199 patients undergoing intravenous pyelograph examination in our hospital from april 2004 to may 2006 were collected, and the nurse means adopted were surveyed.results: supported by right nursing, intravenous pyelograph examination were successfully performed on 1198 patients except one which was sensitive to iodine.conclusions: right nursing is necessary and effective to special patients undergoing intravenous pyelograph examination.

收集2004年4月至2006年5月在本院施行排泄性尿路造影检查共1 199例患者的临床资料，对所采取的护理措施进行汇总分析。结果：在正确的护理措施的支持下，1 199例患者除1例对碘剂严重过敏外，其余均顺利完成排泄性尿路造影检查。结论：正确的护理措施对于施行排泄性尿路造影检查的特殊患者，既是必需的，也是有效的。
