用广角X射线衍射法对晶型结构进行研究，表明碳纤维使原生态的样品中α晶型的含量降低，结晶度下降，其中接枝聚己内酰胺链段的碳纤维／MC尼龙6原位复合材料中α晶型的含量比未接枝的碳纤维／Me尼龙6原位复合材料的多，结晶度也较大：样品淬火时，碳纤维有利于基体尼龙6结晶时形成γ型晶体，接枝聚己内酰胺链段的碳纤维更有利于基体尼龙6结晶时形成γ型晶体；淬火后的样品在200℃下退火2个小时后γ晶型完全转变为α晶型。

Some key algorithms were researched here: a "cut-and-sew" algorithm was presented here to resolve the reconstruction problem of adjacent section contour lines which different from shape and polygon vertex count; a random polygon triangulation algorithm based on CDT was studied to resolve the modeling problem of complex geological model with stones and holes inside; a grid-constraining algorithm of judging whether a point is in a polyhedron was studied here to construct the corresponding geological block model which constrained to wire frame model.

Four testing methods to detect the pollen viability of cucumber were being compared. The results indicated that I-KI staining method and acetic red dyeing were not suitable to judge the pollen viability of cucumber. Tetrazolium method can be used but the error is oversize. By and large, the Germination in vitro method was an efficient, stable and simple way to judge the pollen viability of cucumber. The component of culture medium is 10% sucrose+ 100mg/L H_3BO_3. If inoculated intraday, collect pollen of fresh abloom flower at 6:00 and if inoculated at the second day, collect before dark.

比较了4种常用的花粉活力测定方法——I-KI染色法、醋酸洋红染色法、TTC染色法和离体萌发法，认为I-KI染色法和醋酸洋红染色法不适于测定黄瓜花粉生活力，TTC染色法虽适用但误差较大，综合考虑各项因素，确定离体萌发法是最准确、简便、稳定的测定黄瓜花粉活力的方法。

The study on acetoin crystallization dimer showed that the yield of acetoin-dimer was affected by the optical rotation of acetoin.

对乙偶姻二聚体结晶的研究表明，乙偶姻的旋光值对二聚体的结晶得率影响很大，旋光值越接近于零，结晶得率越高。

The results indicated that a high volumetric ratio of acicular ferrite in the simulated weld metal can be obtained in case the ratio of manganese and silicon is in a certain range.

结果表明，当Si、Mn比在一定的范围时，焊缝中将出现高比例的针状铁素体；且在大尺寸奥氏体晶粒中的非金属夹杂物上形核，高密度微小的夹杂物(1μm以下)的弥散分布对其形核更为有利。

When the pouring temperature is close to the liquidus temperature of AlSi7Mgalloy, the primary α-Alin the billets of AlSi7Mg alloy solidifies into spherical or nodular grainswhich are small and distributed homogeneously. In order to obtain non-dendritic semi-solidbillets,the appropriate pouring temperature is 615℃. The faster cooling rate,the melt flowing and largersolidification region induced by the near liquidus pouring temperature promotes theformation of spherical or nodular primary α-Al.

实验表明：当浇注温度接近液相线温度时，AlSi7Mg合金中的初生α-Al凝固成球状或粒状，晶粒细小，分布均匀；获得球状或粒状AlSi7Mg合金半固态坯料的最佳浇注温度为615℃；在接近液相线温度下浇注，较快的合金熔体冷却速度、浇注引起的合金熔体活动和大范围的同时凝固促使AlSi7Mg合金形成球状或粒状的初生α-Al组织。
