介绍了木瓜的营养价值与保健功能，对木瓜果酒、木瓜保健果醋、低糖木瓜果脯、木瓜果酱、低糖木瓜罐头、木瓜果肉饮料、木瓜保健软糖等产品的开发研究进行了概述。

The dry substance in grape branny oar is to do not have partly character sweet spent dextrin, beyond person mix for dextrose a few maltose, low get together candy low spend carbohydrate, so of fruit juice panocha sweet degree not tall, but nutrition is very rich.

葡萄糠浆中的干固物质一部分是没有甜度的糊精，余者为葡萄糖和少量的麦芽糖。低聚糖等低度糖类，所以果汁软糖的甜度不高，但营养十分丰富。

This paper introduces a frequency source with low phase-noise and low spurs and the performance of the system.

本文介绍了一种低相噪低杂散频率源的设计方法，并给出了最终测试所得的系统性能指标。

Presently, the nucleation and growth mechanism of diamond hasnt been known completely. Thermodynamically, the nucleation and growth of diamond at low temperature and low pressure is still considered as a paralogism.

目前金刚石的热力学成核及生长机理尚不完全清楚，金刚石在低温低压下的成核和生长，仍被认为是一种热力学的"悖论"。

As pairs of connected ramets were subjected to reciprocal patchiness of light and nutrients, stolon connection between the two ramets significantly enhanced biomass of both ramet growing in low light intensity but high soil nutrient condition and ramet growing in high light intensity but low soil nutrient condition as well as whole ramet pairs (consisting of LH ramets and HL ramets).

当生长于高光照低养分条件下分株与生长于低光照高养分条件下分株之间的匍匐茎连接时， 3种克隆植物HL分株、LH分株以及整个分株对系统(HL分株+ LH分株)的生物量均得到显著提高。同时， LH分株根冠比显著增加，而HL分株根冠比显著下降。

Using p-T pseudosections with contours of H20-contents, the medium-low pressure metamorphism for pelite from the Altai orogen was documented. We proposed that the andalusite-type metamorphic zones in Altai were related to the uplifting of kyanite-type zones and are characteristic of isomorphic transformation between aluminosilicates. Generally, it is difficult for the low-pressure metamorphic assemblages to reach an equilibrium state.

利用p-T视剖面图和饱和水含量等值线的行为研究阿尔泰造山带泥质岩石的中低压变质作用发现，阿尔泰地区红柱石型变质带的发生与蓝晶石型变质带的抬升有关，主要发生铝硅酸盐矿物之间的同质多相转变，低压变质矿物组合未能达到热力学平衡状态。
