对重

I choose to relieve myself and disburden myself.

我愿意以轻对重，以轻对累。

This apparatus was designed based on summarizing the most synthetic processes of lactide presently.

本文在总结了目前众多聚乳酸单体——丙交酯的合成技术的基础上，选用减压蒸馏工艺并加以改进，设计出最佳的实验装置，使丙交酯的产率从30％提高到45％，并对重结晶后的母液进行有效的回收，回收率也能达到40％，对回收后的丙交酯进行了测试分析，证明了回收过程的可行性。

The improvement can maintain the speed of the original convergence and is still effective when there are multiple root s.

对牛顿求根公式作了改进，使其对重根情况仍有效，并保持原有的收敛性

The data has been compare for test data and the soft can be used to the study of H.M.Cyclones by the RSM model Of Onflow , the predicted results fit well with test data and the new method has been found out which the study of H.M. Cyclones is used by.

试验结果证明，选用RSM湍流模型可以对旋流器流场进行较全面准确的数值模拟，为从理论上对重介旋流器进行深入研究提供了一条新的途径。

Analysis of resample techniques reduces the sensitivity of the algorithm to noises.

对重采样的分析减少了算法对噪声的敏感。

Some conclusions were drawn: Oenanthe javanica grew normally when TN and TP concentrations in raw water were 7.05-9.99 mg/L and 0.29-0.73 mg/L respectively; with the hydraulic load being 0.5 m^3/(m^2d), the removal rates of NH3-N, TP, and TN from heavily polluted river water by Oenanthe javanica floating bed were positively related to water temperature, and it inhibited the growth of algae stably; the mean removal rate of nutritive salt increased with the concentration of raw water.

研究结果表明，进水ρ和ρ分别为7.05~9.99mg/L和0.29~0.73mg/L，水芹菜能正常生长，在水力负荷为0.5立方公尺/的条件下，水芹菜浮床对重污染河水中的NH3-N，TP，TN的去除率与水温正相关，对藻类的抑制作用稳定；营养盐的去除负荷随原水质量浓度的增加而增大。

The chemical adsorption model of titanite on the surface of finely calcium carbonate was established according to the properties of finely calcium carbonate and titanite and the mutual action mechanism.

硬脂酸钠、钛酸酯和铝酸酯对重质碳酸钙的改性与钛酸酯对硅灰石的改性导致改性剂在矿物表面的反应吸附，吸附以化学吸附为主，物理吸附为辅。

When hemoglobin was ≤8 g/L, the vanadic acid oxidation assay had no interference and the diazo method bad significant interference.

血红蛋白浓度≤8 g/L时对钒酸氧化法无干扰，对重氮法有较大干扰。

Chiral ligands mentioned above and their complexes with acetate copper were used as enantio-selective catalysts in asymmetric cyclopropanation reactions of diazoacetate and 1,1-diphenyl ethylene. Investigations indicate that all of them reveal certain optical-selective capability, but chiral C2-symmetric 2,6-bispyridine ligands show better catalytic capability than chiral asymmetric schifF-base ligands.

选择了2个手性2，6-吡啶双噁唑啉配体和6个手性不对称席夫碱配体与醋酸铜形成的配合物作为催化剂，对重氮乙酸乙酯与1，1-二苯乙烯不对称环加成进行催化反应，发现这8个催化剂对1，1-二苯乙烯的不对称环丙烷化反应都表现出了一定的光学活性诱导能力，手性2，6-吡啶双噁唑啉-铜类具有比手性Schiff碱-铜类更好的催化性能。

"Edelweiss" is a show tune from the 1959 Rodgers and Hammerstein musical The Sound of Music. It is named after the edelweiss, a white flower found high in the Alpine hills. The song is sung by Captain Georg Ritter von Trapp as he rediscovers music and a love for his children. Later on in the show it is sung as a defiant statement of Austrian patriotism by the Von Trapp family in the face of the pressure put upon CaptainVon Trapp to join the navy of Nazi Germany.

雪绒花」是剧作家Rodgers以及Hammerstein於1959年所改编的音乐剧《真善美》中的一首曲目，该曲以一种生於阿尔卑斯山上的白花命名；剧中，Georg Ritter Von Trapp上校不但以「雪绒花」一曲表露他对重拾音乐的感动，以及对子女们的爱；Von Trapp上校一家更在他面临被迫加入德国纳粹海军之际，用「雪绒花」这首歌来捍卫他们的爱国之心。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
