Results indicated that introducing some ring-structure into UF molecule during the synthesis could efficiently improve the water resistance of UF resin. The Uron ring would form if reaction temperature was more than 75 degrees C, and the higher Uron content was obtained at pH 8 and 85 degrees C in the absence of catalyst when the reaction time was long enough.

结果表明：通过在脲醛树脂合成中引入Uron环等环状结构物质能够有效提高脲醛树脂胶黏剂的耐水性；当反应温度高于75℃时，反应产物都生成了一定量的Uron环物质；在pH值为8左右、温度控制在85℃、不使用催化剂、尽可能延长反应时间的条件下，尿素与甲醛成环化反应生成的Uron相对值最多。

The results showed that:(1) low N stress significantly decreased the leaf SPAD value, leaf nitrogen content, nitrate reductase activity and reduced distance between leaf-umbrella, leaf area. And these impact aggrandized as the stress intensity increased.(2) Responses to low-N stress were in different degrees between different varieties of rubber tree seedlings. On the whole, GT1 was most sensitive to stress, PR107 next, and RRIM600 was the least sensitive.(3) The SPAD value, DBL, LA were significantly positive correlated with LNC, NRA in the seedling leaves.

结果表明：（1）缺N胁迫明显降低了叶片SPAD值、叶片N含量和硝酸还原酶活性，缩小了叶蓬距、叶面积，且影响幅度随胁迫强度的加大而增大；（2）不同品种橡胶树实生苗对缺N胁迫的响应程度不同，总体上GT1较为敏感，PR107次之，RRIM600较不敏感；（3）橡胶树实生苗叶片SPAD值、叶蓬距、叶面积与叶片N含量、硝酸还原酶活性之间均呈显著或极显著正相关。

For fiatΛCDM cosmogonies withσ8 normalized by recent weak gravitational lens-ing observations, the best results are obtained forΩ0～0.3;Ω0≤0.2 leads to too large galaxy correlation lengths, whileΩ0≥0.4 gives too high mass-to-light ratios to match the observed TF relation.

对于平直ACDM宇宙学模型，根据最近的弱引力透镜给出的σ8值，条件光度函数模型给出了最佳值为Ω0～0.3；当Ω0≤0.2时，星系相关长度过大；而Ω0≥0.4则给出了太高的质光比，和观测的TF关系不符合。

Six types of sunscreen cosmetics are measured, and the product properties are evaluated by absorbance A. Sunscreen effects tested on three types of cosmetics are disaccorded with SPF values labeled on the products, and the light transmittance in the UV part is high.

Next, regarding question two, because present uses the injection contraceptive the method to maintain this population the stability, moreover already did not have the individual to move away or the situation which poaches, for this reason we transform this populations stability to ask this population every years newborn baby quantity to subtract this year death individual the quantity differential value; Moreover from this population year quantity with this year the end of the years quantity differential value, when tends 0, namely thought that this community individual quantity is stable, thus the question stability problem transforms to ask simple targets optimization problems model building; Carries on using MATLAB to the model obtains, obtains, when did not consider when uncertainty factor influence must inject the medicine female animal quantity is 276 heads, but when had considered after twin and by duplicate injection these two uncertainty factor influence, obtains must inject the medicine female animal quantity is 352 heads, including 110 are by the duplicate injection.

其次，对于问题二由于现在采用注射避孕药的方法来维持该种群的稳定，而且已经没有个体被运走或被偷猎的情况，为此我们把该种群的稳定性转化为求该种群每年的新生幼仔的数量减去该年死亡个体的数量的差值；另外从该种群年头的数量与该年年底的数量的差值，当趋于0时，即认为该群落的个体数量是稳定的，从而把问题的稳定性问题转化为求单目标的最优化问题建立模型；利用MATLAB对模型进行求得，得出当不考虑不确定性因素影响时要注射药物的雌性动物数量为276头，而当考虑了双胞胎和被重复注射这两个不确定性因素影响后，得到要注射药物的雌性动物数量为352头，其中有110头是被重复注射的。

This allows me to modify the object but does not take into account the reassigning of the parameter.

从本质上讲，对象的引用是按值传递的，这样我可以修改对象而不需要考虑给对象重新赋值。

BIAN Zhi-hua,ZHANG Li-jie,JING Feng,YU Mei-wanAbstract: The fissure of soft rock of Mesozoic era and Cenozoic era isn't developmental normally. But there exist many pores in this rock and the cementation intensity of this rock is very low. Easy disturbance is notable. Mechanics parameters are valued after rebating test result of rock block. It makes mechanics index of weak foundation to be greatly lower than actual value.

中-新生代软岩一般裂隙不发育，但孔隙多且胶结强度低，易扰动性显著，其岩块试验成果折减后进行岩体力学参数取值，普遍造成软弱地基力学指标远低于实际值，是目前工程界面临的一大困惑。
