Petiole ca. 3 cm, base ca. 4 mm thick; leaf blade elliptic to ovate-elliptic, 25-30 × 8-10 cm, leathery, concolorous, abaxially covered with minute scalelike trichomes, base broadly cuneate and symmetric, margin entire, apex acute and oblique; secondary veins 12-16 on each side of midvein, adaxially slightly impressed, abruptly curving apically, obscure near margin; tertiary veins subparallel.

坚决，具皮孔的当年小枝，glabrcircaPetiole circcircam，繁茂的基础约4毫米；叶片椭圆形到卵状椭圆形，25-30 * 8-10厘米，两面同色，背面为小鳞片状毛覆盖，基部宽楔形，对称，全缘，先端锐尖、偏斜；次脉每边12-16，正面稍凹陷，顶部突弯，边缘不明显；支脉近平行。

And we show that if such a immersion is also semi-parallel, it must be totally geodesic. Moreover the same results hold for semi-symmetric submanifolds in a nontrivial complex-space-form.

我们证明了如果它还是半平行的，则它必是全测地浸入，而且这一结果对于复射影空间和复双曲空间中的半对称浸入也成立。

Based upon a systematic review on the study of subtropical anticyclone, in this study, the mechanism linking the formation of subtropical anticyclone in boreal summer to zonally asymmetric diabatic heating is investigated via data diagnosis, theoretical study, and numerical experiment. The complete form of the tendency equation for vertical vorticity development, the NCEP/NCAR reanalysis data, and the IAP/LASG GOALS climate model are employed for the study.

本文在回顾有关北半球副热带高压研究的基础上，基于全型垂直涡度倾向方程，利用NCEP／NCAR月平均资料和IAP／LASG GOALS气候模式，从资料诊断、理论研究及数值试验三方面研究了纬向非对称非绝热加热对北半球夏季副热带高压形态变异影响的物理机制。

But some of the familiar stuff includes boxer engines and Subaru's symmetrical AWD.

但是，一些熟悉的东西，包括拳击手发动机和斯巴鲁的对称全轮驱动系统。

Leaves apparently alternate, distichous; nanophylls present or absent, opposite to normal leaves; stipules 2; leaf blade 3-veined, one major lateral vein sometimes inserted above the base, or pinnately veined, base asymmetric, margin entire or serrate; cystoliths mostly present, linear or fusiform.

叶表面上互生，2列；微形叶宿存或无，对生于正常的叶；托叶2；叶片3脉，主要的一侧脉高于那些基部，或成羽状脉，基部不对称，边缘全缘或有锯齿；乳状体多数宿存，线或者纺锤形。

ABSTRACT This thesis focused on the studies of setereoselectively total synthesis of naturally occurring bisabolane sesquiterpenes and hydroxamic acid derivatives; it contains the following five parts: Part Ⅰ: Hydroformylation reaction have been taken an overview for past 40 years.

本论文主要对防风根烯类倍半萜天然产物和羟肟酸类化合物的全合成进行了研究，内容概要如下：一、对近年来氢甲酰化反应——特别是不对称氢甲酰化反应作了详尽的综述。

Corolla infundibuliform, rarely campanulate to salverform, slightly zygomorphic, 5--7-lobed; lobes entire, emarginate or dentate at margin.

花冠漏斗状，对左右对称高脚碟状，稍，5-7浅裂很少钟状；裂片全缘，微缺的或具牙齿在边缘。

But these experiences could be used for reference in the syntheses of flavan like compounds.

这些研究结果为黄烷类天然产物不对称全合成提供了一定的借鉴。

Two approaches for the asymmetric syntheses of naturally occuring eudesmane-type triol kudtriol and 5-epi-kudtriol as well as their C-11 epimers were achieved starting from-dihydrocarvone through six and seven steps, respectively.

以-二氢香芹酮为原料，用两条合成路线分别经六、七步反应完成了三羟基桉烷类天然产物Kudtriol、5-epi-Kudtriol及它们的C-11位差向异构体的不对称全合成。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
