The results showed that acidifier supplementation in the diet at different levels improved feed intake and daily weight gain in a quadratic manner. The supplementation of organic acid improved the availability of DM, protein, organic compound and energy in the broilers at the age of 0-21 days. Comparing with the control test, the supplementation of 0.05%, 0.3% and 0.4% organic acid improved the availability of protein p

结果表明：①饲粮添加不同剂量乐达酸化剂，使肉鸡采食量和日增重呈二次曲线变化；②饲粮添加有机酸能不同程度改善肉鸡0-21日龄饲粮干物质、蛋白质、有机物和能量的利用率，与对照组相比，0.05%、0.3%和0.4%乐达酸化剂组饲粮蛋白质利用率极显著提高p

These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

The Council's decrees record various aspects of this great aggiorniomento. One of the richest documents, Gaudium et Spes, adequately embodies the so-called spirit of Vatican Ⅱ, which emphasizes a personalist view of humanity, highlights holiness as being found in the interaction between the Church and the secular world, and underscores an attitude of openness, tolerance, plurality and catholicity in dialogue with other cultures and faiths.

会议所产生的决议「梵二文件」记载了这一重大革新的方方面面，其中的《论教会在现代世界牧职宪章》，即《喜乐与期望》更是内容最为丰富的一份，充分体现了所谓的「梵二精神」，即强调位格主义的人性、突出教会同世俗世界互动关系中的神圣性、著重同其它不同文化及信仰传统间对话的开放、宽容、多元、合一态度。

The Trojans led by him and by Iamenus, Orestes, Adamas the son of Asius, Thoon and Oenomaus, raised a loud cry of battle and made straight for the wall, holding their shields of dry ox-hide above their heads; for a while the two defenders remained inside and cheered the Achaeans on to stand firm in the defence of their ships; when, however, they saw that the Trojans were attacking the wall, while the Danaans were crying out for help and being routed, they rushed outside and fought in front of the gates like two wild boars upon the mountains that abide the attack of men and dogs, and charging on either side break down the wood all round them tearing it up by the roots, and one can hear the clattering of their tusks, till some one hits them and makes an end of them- even so did the gleaming bronze rattle about their breasts, as the weapons fell upon them; for they fought with great fury, trusting to their own prowess and to those who were on the wall above them.

就像这样，二位凭待自己的勇力和强健的臂膀，站候着高大的、正向他们迎面扑来的阿西俄斯，毫不退让。特洛伊人直冲而上，对着修筑坚固的护墙，高举着生牛皮做就的战盾，裂开嗓门呼喊，围拥在首领阿西俄斯身边，围拥在亚墨诺斯、俄瑞斯忒斯和阿西俄斯之子阿达马斯，以及俄伊诺毛斯和索昂的身旁。其时，墙内的拉丕赛人正极力催促胫甲坚固的阿开亚人保卫海船，但是，当他们看到特洛伊人正冲向护墙，而达奈人则惊叫着溃跑时，二位冲将出去，拼杀在门前，像两头野猪，在山上站等一群步步进逼的对手，骚嚷的狗和猎人，横冲直撞，连根掀倒一棵棵大树，撕甩出一块块碎片，使劲磨咬着牙齿，发出吱吱嘎嘎的声响，直到被人投枪击中，夺走它们的生命――就像这样，挡护他们胸肩的捏亮的铜甲承受着枪械的重击，发出铿锵的震响。

In the presence of catalytic rhodium acetate, ethyl 2-diazo-3-oxo-per fluoroalkanoates, reacted readily with nitriles to give a series of 5-fluoroalkyl substituted 1, 3oxazoles with high regio-selectivity through a metal carbenoid intermediate. The reactions of carbenoids with noncyclic vinyl ethers or cyclic vinyl ethers afforded dihydrofuroates in good to excellent yields. Interestingly, only vinyl C-H insertion compound was obtained concerning of the reaction of carbenoids with 2, 5dimethylfuran due to the steric hindrance of methyl group
