The introduction of one way to solve the problem of definite integral by means of double integral.

介绍利用二重积分解决有关定积分问题的一种方法。

The virgin thermoplastic polyurethane and the thermoplastic polyurethane of the scrap material are polymerized using at least about 60 percent by weight, based on the weight of the polyurethane produced, of a polyester diol having a weight average molecular weight of at least about 500 and having from four to five carbon atoms between substantially all of the ester groups.

未使用过的热塑性聚氨酯和废料的热塑性聚氨酯是使用至少约60wt％的聚酯二醇聚合而成的，基于产生的聚氨酯重量。其中该聚酯二醇的重均分子量为至少约500，并基本所有的酯基团之间均有4～5个碳原子。

The paper introduces the method of calculating double integral with symmetry,and then puts forward a calculating method by rebuilding integrand and domain of integration reasonably.

本文还介绍了如何利用对称性来计算二重积分，并提出了通过适当改造被积函数和积分区域以利用对称性来简化计算的方法。

By using the limits of functions and the exchange limit theorem,we considered the relationship between the double limit of function with two variables and its repeated limit s.

应用函数列的极限与函数的极限交换次序定理，研究了二元函数的二重极限与它的两个累次极限的关系定理，研究了二元函数的两个二阶混合偏导数可交换次序定理。

The specialties of time in modernity and the time-hating, the modern theme of leaving home and going home, taking Ba Jing as a case study; 5. The research on the space of modernity and the space-hating, taking Yu Dafu's dual spaces, that is, the space of degenerating and the space of reclusion as the subjects to analyze.

这一问题域的展开遵循如下次序：一，现代精神中的怨恨之发生；二，启蒙伦理的怨恨背景以及现代性怨恨对古典价值秩序的颠覆；三，父与子的主题，统治与解放的辩证法；四，现代性时间的特点与时间怨恨，离家与回家的现代主题，以巴金为个案；五，对现代性空间以及空间怨恨的分析，以郁达夫的二重空间，沉沦与隐逸的空间为分析模型。

DPU at a concentration of as low as 10^(-7)mol/L retained the chlorophyll of Spirodela half-fronds under long-day conditions. From 10^(-5)~2×10^(-4)mol/L it prompted the synthesis of chlorophlly and the serine: glyoxylate aminotransferase activity, increased dry weight, and retarded the senescence of half-fronds.

在长日照条件下，10^(-7)mol/L的二苯脲对紫萍半叶状体就有保绿的作用，10^(-5)~2×10^(-4)mol/L的二苯脲还可以明显地促进叶绿素的合成和干重的增加，提高丝氨酸：乙醛酸转氨酶的活性，延缓半叶状体的衰老。

Methods seventy-two 15-week-old sd rats were divided into six groups,included control group and five ovariectomized model groups.the model groups were fed with different-dose lycopene［10,15,20 mg/］ for 12weeks.then related indexes including length bone mineral density,bone mineral,serum estradiol,sertum alp and uterus index were analyzed.results compared with model group,three different dose groups and nilestriol［1.05mg/］ group showed increased bone mineral density,bone mineral,serum estradiol and uterus index,but decreased serum alp (p.05).conclusion as a female sex hormone-like component,lycopene may ameliorate the bone quality and inhibit osteoporosis in ovariectomized rat.

将72只15周龄sd大鼠随机分为6组，空白组做假手术，其余5组做卵巢切除术，术后用药12周后处死，测定右侧股骨骨密度、骨矿含量、血清雌二醇、碱性磷酸酶含量及子宫湿重。结果番茄红素高［20mg/］、中［15mg/］、低剂量组［10mg/］、尼尔雌醇组［1.05mg/kg·bw］能对抗骨密度、骨矿含量、血清雌二醇的下降、血清碱性磷酸酶的升高，与模型组比较，p.05；番茄红素各剂量组、尼尔雌醇组能对抗子宫指数的减轻，与模型组比较，p.05。结论番茄红素可以改善骨质量，抑制大鼠去卵巢骨质疏松的发生。具有类似雌激素的效应。

By using the way of double proof, we will do our best to combine the unearthed literature with literature handed down from ancient tunes. Quotative poems and materials of the above, confirmed that the two are dubbed "a poem that goes" or "Confucius" in quotation style, but to the Mencius and Xunzi were replaced by "Confucius said", the usual writing habits and the evolution path, as evidenced by a blood relationship between them.

采取&二重证据法&的研究方法，即通过详细地辑录二书文本引诗用诗的&文本材料&，并与郭店楚简和上博简文等新出土的&地下材料&相互释证，证实二者均惯用&诗云&或&子曰&的引语样式，而到了孟、荀则改用&孔子曰&的通常写法，文字习惯的演变轨迹，可证学庸有血脉关系。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
